Description

Building construction method using lattice typed cable structure in the plane}

The present invention relates to a structure construction method using a flat grid cable structure. More specifically, the present invention relates to a method of constructing a structure by using a cable structure used in a long span bridge, a steel framed multi-storey building, a membrane structure, and a large power transmission tower. In the case of a long span bridge (a suspension bridge or a cable-stayed bridge), a cable is formed in a horizontal plane lattice shape. By installing both sides in the cable yard of the alternating or pier, and by mounting a plurality of bridge top plate on the top surface of the cable to be fixed to build a long span (span) bridge without the installation of the main tower, in the case of multi-storey multi-storey building After completing the pillars and the bottom frame, the floor structure is installed without additional installation of the inner pillar by fixing the flat grid-shaped cable to the outer pillar on the bottom surface of the bottom frame, and in the case of the membrane structure, the plane connecting the roof frame pillar and the pillar After installing the grid cable of the horizontal, the horizontal beams, hinge beams and stringers, And by installing a membrane structure such as a roof on the upper side of the cable on the top of the beam, construct a large membrane structure without additional installation of intermediate reinforcement beams such as horizontal beams or longitudinal beams, and in the case of power transmission towers, install minimal transmission columns instead of large transmission towers. After installing the flat grid type cable in the transmission pillar, the transmission wires are connected to the cables with insulators to distribute the load by the wires, eliminating the need for the installation of large transmission towers. It relates to a structure construction method using a flat grid cable structure that can be constructed in a form supported by.

In the case of constructing a long span bridge using a conventional cable, as shown in FIG. 1, after installing a plurality of pylons and bridge decks on a bridge or bridge, the cables connecting the pylons and the bridge decks are radial, half, and fan. The type of cable-stayed bridge or suspension bridge is used. This type of bridge construction has a structural feature that enables bridge construction of long spans by connecting bridge tops to cables and transferring external loads to bridge tops to the main tower through the connecting cables.

However, in the case of the bridge type, in order to build a pylon, which is a fixed or hinged part of a cable, a massive temporary facility (for a bridge across a wide river, a pylon foundation must be installed in the middle of the river to install a pylon. The installation cost of the pylons is very high in the construction cost of the undercarriage of the bridge. Since the pylon supports most of the loads on the bridge, the longer the span of the bridge, the higher the height of the bridge is. In particular, in the case of the suspension bridge type, the longer the span, the weaker the torsional rigidity caused by the wind load, so that the thickness of the bridge deck must be increased to solve this problem. There is a structural disadvantage.

In addition, in the case of a conventional steel frame multi-storey construction, after installing a plurality of external steel pillars, the horizontal beams and vertical beams are installed on the steel pillars, and deck plates are usually installed thereon to construct the floor plate. However, as the building becomes taller and larger, the fixed load will inevitably increase, which inevitably increases the number of internal steel pillars to support the load of the bottom plate, which in turn increases the cost of construction costs. There is also a method of reducing the number of steel pillars by increasing the material strength of the steel frame, but this has the disadvantage that there is a limit.

In addition, when constructing a conventional membrane structure, after installing the roof frame pillar, a plurality of cross beams and stringers are installed on the roof frame pillars, and the roof is placed on the cross beams and stringers to complete the roof, and in the case of a large membrane structure such as a hangar. After installing the three-dimensional truss on the frame of the roof, the roof is installed. However, when the horizontal beams and vertical beams are installed, the construction cost is increased according to the beam installation, and even when installing the truss structure, the truss installation cost is quite expensive.

In addition, in the case of a conventional transmission tower construction, a large transmission tower is installed at regular intervals to support a load by a large-capacity transmission wire. In general, transmission towers are mostly installed in Korea via mountainous areas, and thus, the construction cost thereof is quite expensive.

Therefore, the present inventors do not need the installation of the main tower for the cable connection in the case of long span bridge construction, devised a cable structure to install the cable in a grid to the plane to solve the problem of the lack of twist stiffness the flat cable upper surface It solves the problem of long span bridge construction by connecting bridge top plate on top of it.In case of steel frame multi-storey construction, flat grid type cable is installed at the bottom of steel bottom plate, so the steel bottom plate compresses and the cable bears tension. It is possible to support the external load applied to the sole plate only by framing, eliminating the need for many internal framework pillars and solving the problems caused by the increase in the size of steel structures, and in the case of membrane structure construction, the present invention is applied to roof pillars and beams. Install the flat cable of the cable to load the roof load It is possible to construct a membrane structure such as a large roof by constructing a large roof, and without installing a large transmission tower, by installing a minimum transmission pole, fixing a flat cable to the pillar, and installing a transmission wire using insulators on the cable There is no need to install the transmission tower, and furthermore, the flat grid type cable structure and structure construction method using the same have been developed to support the loading structure using the flat grid type structure, eliminating the additional installation of intermediate reinforcement, and to be used for the construction of the structure.

The present invention minimizes the structure of the intermediate support structure by using a flat grid cable structure in various structures, such as in the construction of construction structures using cables, that is, long span bridges, multi-layered steel structures, large membrane structures and large transmission towers, etc. As for the construction method to complete

An object of the present invention, in the case of a long span bridge, can be omitted the construction of the main tower for the installation of the cable, by installing the cable in a grid form in order to ensure the torsional rigidity by installing the bridge top plate on it It is possible to reduce the cost of construction work and the risk of height work due to the construction of the main tower, and to install a wide cable in the plane, and then put the bridge deck on top to provide a means of increasing the torsional rigidity of the bridge deck. It is to provide a structure construction method used.

Another object of the present invention is a crossbeam and vertical beam installed in the inner steel pillars by installing a flat grid cable of the present invention in the bottom plate steel frame, without the installation of a separate inner steel pillars between the outer steel pillars in the case of a steel frame multi-storey building By providing a role of to provide a structure construction method using a flat grid-type cable structure that provides a steel frame base plate construction means that almost no internal pillar even in the case of large steel structures.

It is still another object of the present invention to provide a support structure for placing a roof between roof frame pillars in the case of large membrane structures such as roofs, and to plan cables on roof posts and at least installed beams without installing vertical beams, cross beams and three-dimensional trusses. It is to provide a structure construction method using a flat grid cable structure that can be installed in a lattice form, a roof on it, and economically install a membrane structure such as a large roof.

Another object of the present invention is to provide a structure construction method using a flat grid cable structure that can be installed economically by applying the flat cable structure of the present invention to a large transmission tower, by increasing the distance between the transmission tower as possible. .

Another object of the present invention is to compensate for the expansion and contraction caused by the external environment caused by the material of the cable when the flat grid cable structure of the present invention is fixed to the fixed support of the end and the like in the case of bridges, etc. Means to provide a, that is to provide a saddle-type compensation device or a spring-loaded compensation device.

It will be described in detail with reference to Figures 2 to 8 which is an embodiment according to the type of the structure to be applied to the flat grid cable structure of the present invention.

The flat cable structure of the present invention basically forms a cable, that is, a steel wire, a steel bar, or a strand, which is alternately formed in a lattice shape and manufactured as a wire mesh type as a whole. Hereinafter will be described based on the embodiment according to the type of structure (for long span bridge, steel frame multi-storey building, large membrane structure and large transmission tower).

Example 1 (for long span bridge)

2A is a conceptual diagram when the flat grid cable of the present invention is applied to a long span bridge. Among the cables of the present invention, the main cable 101 is fixed to be installed across the river in the cable fixing device 103 installed at regular intervals on both sides of the river, and the bending moment due to the sag of the main cable of the long span in the middle of the river. Pier 104 is installed to offset. The number of piers and cable anchors can be adjusted according to the width of the steel, and the piers may not be installed depending on the material rigidity of the main cable, the basic type of cable anchors, and the width of the steel (W).

In addition, the plurality of hanger cables 102, which prevent the longitudinal displacement of the main cable and serve as a support for the bridge deck, are installed at right angles to the main cable at regular intervals on the main cable, so that the main cable and the hanger cable are generally lattice type. Installed in a wire mesh shape of the flat grid cable 100 structure of the present invention is completed.

In FIG. 2A, the hanger cables 102 are installed at equal intervals at right angles along the entire length of the main cable, but as shown in FIG. 2C, a plurality of hanger cables are installed at regular intervals from both ends and hangers at both ends. Auxiliary hanger cable 109 may be additionally installed at regular intervals in the direction in which the main cable is installed between the cables. Since the main cable is installed without intermediate support, there is a risk of shaking due to wind, etc. As shown in FIG. 2C, a structure for distributing the tension of the main cable by the damper pillar 106, that is, the load of the bridge deck installed on the cable, is shown. Instead, a pillar with a damper can be installed to offset the shaking caused by external loads (wind, etc.) for the intermediate support of the main cable.

The width D of the flat cable by lattice mounting of the main cable and the hanger cable is adjusted according to the size and length of the bridge deck 105 to be installed. As shown in Fig. 2A, the width should be at least larger than the width of the bridge deck. Therefore, unlike the construction method of the cable-stayed bridge or suspension bridge that connects the cables to the main tower, it is not necessary to install the main tower, and if the width (D) of the cable that can support the minimum bridge deck is secured, it is not only aesthetically beautiful but also the construction of the main tower. The construction cost can be reduced, and the obstacles to the visibility by the pylon can be solved, and the safety accidents caused by the aerial work can be prevented.

The bridge deck 105 crosses the river at approximately an intermediate position of the hanger cable, as shown in FIGS. 2B and 2A showing the elevation of the bridge with the bridge deck mounted on a flat grid cable. Install on top of right angle to installation direction.

3 illustrates a connection type of the bridge deck 105. In the case where a plurality of bridge top plates are installed as shown in FIG. 3A, the connecting portions of the bridge top plates are coupled so that the toothed ends are engaged with each other, and then the connecting rod 107 is inserted through the toothed connection portions and simply installed. Can be. The bridge deck is installed in the field after the manufacture of I-shaped girders or box-shaped girders. Unlike the bridge deck of general cable-stayed bridges or suspension bridges, the bridge deck is not suspended from the pylon, but the bridge deck is placed on the top of the flat cable, so the bottom of the bridge deck is supported by the cable and the torsional rigidity does not have to be large. In the case of box girders used as bridge decks, the thickness can be significantly reduced. In addition, as the connecting rod is connected to the bridge top plate by the hinged state, the generation of the parent moment is significantly reduced. Since it is free to rotate, no bending moment is generated so that the bridge top plate can be installed continuously. There is a structural advantage.

3B is a diagram illustrating the connection of the bridge deck and the flat grid type cable using the cable fixing tool 108. That is, a square cable fixing tool capable of supporting the connecting portion on the lower surface of the connecting portion of the bridge top plate connected by the connecting rod may be formed in the direction of the hanger cable installation to support the connecting portion.

Figure 4 is a modification of the first embodiment of the present invention, Figure 4a is a horizontal main cable 110 is installed two horizontally across the river, a plurality of parts in approximately three equal parts of the two main cables It is installed inclined to both sides of the inclined column cable (111) with the cable fixing device as a point, and the horizontally formed flat grid structure that installs the hanger cable (102) at right angles to the three divided parts. The cable is installed right after the hanger cable at right angles. When the cable fixing device is easy to install and the base support capacity can be expected to support the tension of a large number of main cables, the inclination angle between the cable fixing device and the bridge deck can be secured to the maximum. The dead and live loads can be minimized and the axial force of the bridge deck can be minimized, thereby minimizing the thickness of the bridge deck. There is a disadvantage that it is necessary to reinforce the connection between the main cables because the load transmitted from the bridge deck is concentrated on the third part of the two main cables. In order to overcome these disadvantages, a plurality of types of connecting portions between the main cables can be installed in a half type as shown in FIG. 4B. Furthermore, as shown in FIG. 4C, a fan type (connecting portion between the main cables rather than a half type) can be installed. Installation interval of the narrow), and as shown in Fig. 4d, a plurality of connecting portions between the main cables, and the main cable that is inclined to the two horizontal main cables are collected in one place on both sides Can be installed as

In addition, Fig. 4E, which is another modification of the first embodiment, is a structure (multi-span composite structure) in which two or more of the methods shown in Figs. 4A to 4B are combined, and both sides of the steel are radially installed with the main cable 101. , Middle part is the way to support by connecting the main cable to the piers (104).

Figure 4f is another modification of the first embodiment in the form that can be used when the bridge can not be installed in the middle of the steel radially installed the inclined main cable 111 on both sides of the river, but the main cable of both sides crossed It is a bidirectional radial type that is installed up to the bridge deck. FIG. 4e and FIG. 4f in the bridge deck is installed as in Fig. 4a-4d.

4a to 4f, the main cable is radially installed, and the hanger cable is installed at right angles to the main cable between the two main cables. After the surface is installed, or without installing the two horizontal main cables, a normal bridge deck is installed across the river, and the main cable is directly inclined to the bridge deck as shown in FIGS. 4A to 4F. 4G, which is another modified example of the first embodiment, uses a main cable and a hanger cable, but the main cable between the ends of the auxiliary pillars 112 installed at both shifts. 101, respectively, and hanger cables 102 are installed between the main cables at regular intervals perpendicular to the direction in which the main cables are installed, so that the hanger cables are inclined downward. It is characterized in that the fork is formed, the installation of the bridge deck 105 in the middle portion of the hanger cable is the same as the first embodiment and its modifications described above. This method adds an additional type of construction of a separate auxiliary pillar to the shift, but it is a useful method when it is not possible to secure enough site for the required main cable to be installed. In addition, the size and height of auxiliary pillars are changed according to the installation interval of the main cable and the size of the bridge deck. That is, by installing the auxiliary pillar 112, the main cable is not fixed to the alternating side by the cable fixing device, but the auxiliary pillar serves as the main cable fixing device, and a plurality of hanger cables are perpendicular to the main cable installed between the auxiliary pillars. After installing inclined downward, the bridge top plate is installed on the center of the hanger cable, and the use of the auxiliary hanger cable 109 in the direction of the main cable installation between the hanger cables is the same as that of the first embodiment and the modified examples thereof.

In addition, the flat grid cable of the first embodiment is installed in the form of a bridge, as well as a bridge over the long span, that is, rail installation, overpass installation, overpass installation, monorail installation, bridge over the valley, oil and gas pipe installation facilities In the case of structures that require the installation of structures such as pylons of long-span bridges, such as bridges for bridges and intermediate support structures, they can be used in the form of not installing pylons and intermediate support structures. Of course, it is also possible to use it in the case of installing a slope with a cable type structure and installing a staircase, a beam, a roadway between the hanger cables among the cables.

In the case of the installation of the overpass, the overpass is usually used in the case where it is not possible to widen the width of the existing road despite the high traffic volume. It is necessary to minimize the piers. However, if the high-rise bridge deck is constructed with a long span, the pier must be enlarged in order to secure the maximum supporting capacity of the bridge, which increases the installation cost. Therefore, the long span overpass should be installed to the minimum size, the main cable should be installed on the flange of the pier using the cable fixing device, then the hanger cable should be installed at right angles to the main cable, and the overpass at the top of the main cable and the hanger cable. If the bridge decks are installed on top of each other, long span overpasses can be constructed without the need for oversized bridges and bridge decks. The main cable and the hanger cable can be installed in the same manner as the long span bridge.

<Example 2 (for steel frame multi-story building)>

5a is a conceptual diagram of an embodiment in which the flat cable structure of the present invention is applied to the bottom frame of a multi-story building by steel frame. That is, a plurality of floor steel frame 203 is provided between the outer pillar 204 and the outer pillar, and the flat grid type cable of the present invention is installed on the bottom surface of the bottom steel frame as shown in FIG. The cable connects the main cable 201 to the outer pillar and installs the hanger cable 202 at regular intervals between the main cables so that the hanger cable prevents the positional change of the main cable. 200 is completed.

The bottom plate steel frame bears the compressive force due to the external load applied to the bottom plate and the cable installed under the bottom plate bears the tensile force to complete the bottom plate without the inner pillar installed on the bottom plate. That is, when the bottom plate is widened, it is necessary to establish a plurality of inner pillars inside the outer column to reduce the 퓜 moment caused by the deflection due to the self-weight and the live load of the bottom plate, and secure the flexural rigidity capable of supporting the bending moment with only the cable of the present invention. (A cable is a combination of a main cable and a hanger cable that distributes the tensile force applied to the floor frame to the floor plate frame through the cable.) It has a structural advantage of eliminating the process of installing an inner column. .

Although not shown in the drawings, the flat grid type cable of the second embodiment may be used not only in the case of a steel framed multi-story building, but also in underground facilities such as an underground walkway, a ceiling of an underground roadway, or a ceiling of a stream covering structure.

Example 3 (for membrane structure)

6 is a conceptual diagram of an embodiment in which the flat grid cable structure of the present invention is applied to a roof frame of a large shell structure. That is, as shown in FIG . 6 between the roof frame pillar 303 and the roof frame pillar, a plurality of main cables 301 are connected to the roof frame pillar, and then the middle portions of the plurality of hinge beams 306 are connected. Fixed and installed in the cable, and connected to a plurality of hanger cables 302 at the inner end of the hinge beam 306 to secure to the opposite hinge beam to form a flat grid net and then the horizontal beam 304 at the outer end of the hinge beam 306 The stringer 305 is fixed and connected to form a rectangular flat grid.

That is, since the hanger cable is connected to the hinge beam and is formed in a lattice shape, the overall shape of the main cable and the hanger cable is formed in a flat lattice type cable 300 structure.

When the flat grid cable structure is completed, a large membrane structure (dome-shaped roof structure or plate-shaped roof structure) is installed on the cable upper surface. In the case of the membrane structure, all external loads are transferred to the membrane and the structure supporting the membrane, and in general, a considerable tensile force is applied to the supporting structure. To support the tensile force, the supporting structure must have a very large thickness and flexural rigidity. In the present invention, there is a structural advantage that the membrane structure can be constructed by minimizing the thickness for securing the length and strength of the cross beam and string beam to be installed on the roof pillar by using the main cable and the hanger cable which are advantageous for the support of the tensile force.

Although not shown in the drawings, the third embodiment can be used not only for membrane structures such as dome stadiums, greenhouses, plastic houses, but also for windmill structures for wind power generation by gathering the winds in one place. Can be.

Example 4 (for transmission tower)

7 is a conceptual diagram of an embodiment using the flat cable structure of the present invention in a large transmission tower. In order to supply a plant or a house that requires electricity generated from a power plant, a high-voltage cable for transporting electricity in a wired form and a transmission tower supporting the high-voltage cable in the middle are required. When connecting a plurality of high-voltage wires to the transmission tower, the transmission tower is often manufactured in a large three-dimensional truss structure, but the transmission tower is usually installed via a river or a mountain, the installation cost is quite expensive. Therefore, if there is no big obstacle in terms of appearance, it is necessary to connect as many high-voltage cables to the transmission tower as the distance between the transmission towers supporting the high-voltage cables increases, so that the compression force and bending moment applied to the transmission tower become large, thus making the transmission tower large. Therefore, as shown in Figure 7a, without installing a large transmission tower to install a minimum transmission pole 403 and the main cable 401 in the flat type of the present invention between the pillars, and at a certain interval on the main cable To install the hanger cable 402 or the angle alternately, install the insulator 404 that can connect the transmission wire to the upper or lower part of the approximately middle portion of the hanger cable or angle, and to the plurality of insulators When the wire 405 is connected, the load transmitted through the insulator is distributed to the poles by the cable, so even if a plurality of wires are installed, the number of the poles is reduced, and the construction cost can be saved because it is not necessary to install the wire in large size.

In addition, Figure 7b is another modification of the flat cable structure used for the transmission tower, Figure 7a is formed in a horizontal plane of the cable but the cable is configured in a vertical plane. Similarly for vertically formed cables, the load from the wires can be distributed to the columns at each connection, minimizing the size and dimensions of the columns.

Although not shown in the drawings, the flat grid type cable of the fourth embodiment may be used for supporting the orchards of orchards or for installing a net for preventing tidal damage, installing a cable car, and ski resort lifts. In other words, in the case of the net for preventing damage to the tide, install a plurality of pillars for supporting the net around the fruit tree, install the main cable horizontally between the pillars, and install the hanger cable with the main cable, and then install the net thereon. The load of can be sufficiently supported by the main cable and the hanger cable so that a large area of the net can be easily installed even with a minimum number of pillars. In addition, when installing a ski lift or cable car, a large support tower or column is erected to install a cable for the lift or cable car. If the length is long, a large number of support towers and columns can be installed to the target point, and the number can be increased to reduce the number. There is only a lot of difficulties due to the limitation of the installation place. Therefore, install a minimum support tower or pillar, connect the main cable and the hanger cable, and install the cable connector (connector for cable car cable and lift cable to the hanger cable) to the hanger cable, and then If the lift is installed, the support tower and the pillars can be minimized and optimized in the long distance. Installation of the main cable and the hanger cable for the mesh, cable car and lift is the same as that of the large transmission tower.

In the case of construction of long span bridge construction, steel framed multi-storey building, large membrane structure and large transmission tower using the flat cable (100, 200, 300, 400) structure of the present invention, when installing the main cable and hanger cable by the external environment (temperature or humidity) Shrinkage and expansion occur due to the material properties of. Therefore, there is room for stress such as unexpected tensile force in the design stage of the main cable. Therefore, the apparatus 500 and 600 used to compensate for deformation due to contraction and expansion of the cable will be described with reference to FIG.

8A is a conceptual diagram of a thermal expansion and contraction compensation device 500 (saddle type) of a cable installed at a point 503 at which the cable is fixed, wherein the device is a thermal expansion spring 501 installed at a point, and the upper portion of the thermal expansion spring. It is configured to include a roller 502 is installed at the end of. That is, to compensate for the expansion and contraction of the cable according to the external environment is to use a spring that expands and contracts according to the external environment. Therefore, when the cable expands due to high outside temperature, the cable will loosen, reducing the tension of the cable.As the spring expands upward (expand to a length sufficient to compensate for the reduced tension), the cable will stretch again. It can compensate for the reduced tension. In addition, when the external temperature is lowered and the tension of the cable is increased, the thermal expansion spring is also reduced, so that the increased tension can be compensated as much as the reduced length.

8B is a conceptual diagram of a thermal expansion and contraction compensation device 600 ( anchor connection type ) of a cable installed at a place where a cable is connected, to install an anchor 601 at a portion where the cable is connected to each other, and to have a thermal expansion spring 602 connected thereto. Thus, when the cable contracts due to an increase in the external temperature, a compressive force is generated in the cable according to the shrinkage amount, and the compressive force is compensated by the elastic force of the spring, so that deformation of the cable can be compensated according to the external environment. When the external temperature decreases, the action is reversed to the case where the external temperature increases.

The cable formed by the planar structure of the present invention connects the main cable and the hanger cable to the grid to distribute the load by various structures transmitted from the top of the cable to a plurality of points to which the cable is fixed. In order to secure the size and rigidity, when it is applied to the bridge of long span, it is possible to omit the large pylon installation work by placing the bridge top plate on the flat cable, and thus reduce the construction cost and safety by height work The risk of accidents can be reduced, and in case of steel framed multi-storey building, the floor slab of a large area can be constructed without the installation of the internal pillar for supporting the floor plate, so that the internal space of the building can be efficiently used, and the internal steel pillar installation work The construction cost can be reduced by omitting the Even when installing on the installation, the membrane structure is placed on the cable formed on the beam installed on the roof pillar, so that no large support beams are needed.In the case of the installation on the large transmission tower, the installation of the large transmission tower by distributing the load by multiple wires to the multiple columns It provides a means to install power lines without transmission. Furthermore, it provides the means to build the minimum pier and pillars for economical construction of overpass in the construction of long span overpass, cable car installation and lift installation.

It also provides a thermal expansion compensation device (saddle and anchor connection type ) for connecting the cable of the flat grid type to the point, or to prevent deformation of the cable tension by thermal expansion or contraction of the connection portion of the cable.
