Description

TECHNICAL FIELD The present invention relates to a construction method for use in forming a concrete structure such as a wall around a building, an outer wall of a building, an inner wall or a partition wall, a retaining wall, and a civil structure, and a connection method that does not use a temporary material. .

Conventionally, when constructing walls around buildings, outer walls of buildings, inner walls or partition walls, retaining walls, and civil engineering structures, formwork such as veneer formwork, steel formwork, and resin formwork is used as foam ties and steel pipes. A large number of temporary materials such as butters and auxiliary bars are used to assemble the formwork, and the concrete is placed in it. It is constructed by a stacking method for each floor, and after the concrete is hardened, the formwork is dismantled, and finishing such as applying tiles or other decorative materials as necessary is performed. The dismantled formwork and temporary materials are stored for reuse. In addition, for the fence around the building, concrete blocks and precast concrete are used, and the reinforcement is inserted through the hollow part.

On the other hand, there is also a heat insulation wall construction method in which a heat insulating material is fixed to a driving form for constructing a frame of a concrete structure. Moreover, what utilized the heat insulating material as a formwork is generally known. However, even if it is a driving | running mold form or a heat insulating material form, the connection method and shaping | molding of a mold form are complicated, and cost becomes high.

The above-mentioned formwork for dismantling is inaccurate and has hindered the widespread use of reinforced concrete houses due to many occupations, complicated work, long construction period, and high costs due to measures against condensation. However, disaster-resistant houses that can withstand all kinds of disasters, such as reinforced concrete houses, are strongly desired nowadays with many disasters.

In addition, the following patent document can be mentioned as a well-known technique relevant to this invention.

JP-A-8-120802, JP-A-10-317556, JP-A-9-4098, JP-A-9-4098, JP-A-11-81333-81335, JP-A-2004-324369, Japanese Patent Application No. 2007-31513,

However, there have been the following problems in the formwork and driving formwork for the purpose of dismantling, which constructs a conventional concrete structure frame.

The conventional formwork for dismantling is ordinary concrete with a period of retention of 3 days or more at 15 degrees Celsius or more after the curing period or after the concrete is hardened. In the case of a small-scale structure, it is difficult to continue the work because of the temporary support of the slab and the dismantling of the formwork.

Conventional formwork for dismantling requires formwork assembly and formwork dismantling, transportation of formwork and temporary materials, storage of them, etc. Disassembly of formwork and formwork takes a lot of time. Since it requires labor and skill in the work itself, the problem of increasing construction costs including transportation costs and storage costs due to soaring gasoline due to a rise in construction costs and a delay in the construction period in combination with a shortage of craftsmen in recent years. have.

The formwork for the purpose of dismantling is a stacked construction method for each floor regardless of the scale of the structure.

Formwork intended for dismantling requires a large amount of formwork and nails, storage of temporary materials, etc., and costs such as organization.

The formwork for dismantling has a lot of on-site processing, so the accuracy is poor, and concrete suspension work occurs. In addition, the concrete leakage discharges concrete waste and dust by drying, industrial waste such as waste material generated at the time of dismantling and concrete fragments by suspension, and the treatment cost is great.

The formwork for dismantling is inaccurate, so in parallel with the formwork, empty pipes for electrical wiring, pipe sleeves for water supply and drainage equipment, placing concrete, and drawing the main pipe and wiring . As a result, each facility construction requires a lot of labor and cost, such as concrete suspension work due to large loss and inaccuracy.

On the other hand, various types of molded plates in which connecting members and the like are embedded are proposed and used for the driving form, but all of them have a complicated structure and a high manufacturing cost.

In concrete buildings, the construction of external insulation is important. For the construction of the outer heat insulation, there is a method of casting into the concrete using a molding material such as foamed synthetic resin as a mold, but the thickness for giving the strength of the foamed synthetic resin and the foundation for complex molding / finishing The wall thickness including the finishing material, such as the configuration, becomes very thick, resulting in wasted area.

The present invention has been made in view of the above-described problems, and the object of the present invention is that it does not require a skilled worker having technology, can be easily constructed by a multi-skilled worker, has a short delivery time, low cost, and high cost. An object of the present invention is to provide a connection method that can construct a quality concrete structure and does not use a driving mold and a temporary material.

In addition, the present inventor of the present application has already made a solid wood decorative placement form that does not use a temporary material, and connects a solid wood makeup placement form fitted with a connecting member with a cane with a hook-shaped separator. And Japanese Patent Application No. 2007-62733.

However, the proposed one is a solid wood decorative placement form that makes the most of the characteristics of solid wood, but it requires multiple dovetail processing on the placement formwork, and its enormous amount of ant Breaking the cones used for grooving, and preventing the drop-off of the bowl-shaped separator are very expensive, and the cost increases. An object of the present invention is to provide a connection method that can be quickly connected without requiring a high level of technology, and is connected by a connecting member in which a connecting portion and a separator are integrated, and does not use a driving mold and a temporary material. .

4. A driving mechanism characterized in that it is possible to construct a multi-story driving form by connecting and fixing the driving form according to any one of claims 1 and 3 on the basis of a fixed fixed pulling. A formwork construction method (claim 10) is provided.

Since the present invention is configured as described above, the following effects can be obtained.
By connecting the inner and outer driving molds, the connecting member and the lattice member to each other, the connected driving molds become strong driving molds. There is no need for on-site processing for connection, and there is no need to use temporary materials that have been used in large quantities in the past. Can be built.

By connecting and fixing, the plurality of driving molds become a single plate, and a strong driving mold can be constructed. Therefore, if it is a small building of about three floors, all the formwork can be completed and concrete can be placed simultaneously.

By placing concrete at the same time, it is possible to construct a concrete frame that does not require waterproofing work such as balconies and rooftops. In addition, since no concrete is spliced, water leakage from the splicing can be prevented, and the caulking process for splicing is unnecessary. Furthermore, since the slab driving form is not dismantled, it is possible to cope with waterproofing by placing a sheet on the slab driving form.

The solid wood decorative casting form is superior in heat retention and heat insulation, and therefore becomes an indoor and outdoor heat insulating material, and indoor and outdoor heat insulating walls are formed that do not cause indoor condensation. In addition, by increasing the thickness of the solid wood casting formwork, it becomes an outer heat insulating wall suitable for cold regions. The main feature of the solid wood driving form is that it is easy and quick to construct an outer heat insulating wall, which has been considered difficult with conventional construction methods.

Covering concrete with a solid wood casting formwork makes it easier to construct than wooden structures and uses and installs ready-made sashes as easily as conventional wooden houses.

By driving a solid wood veneer formwork into concrete, the solid wood cast formwork prevents deterioration of the concrete surface and protects the concrete, thus extending the useful life of the building.

By making it into a casting formwork, all of the formwork dismantling, keren, nailing, transportation, storage, etc. are unnecessary, and construction costs and industrial waste can be greatly reduced.

By using the cast formwork, it is possible to shorten the concrete curing period and to achieve a short delivery time, low cost, and high quality construction that does not require complicated processes or special engineers.

Solid wood casting formwork is made difficult to burn by integrating with concrete, wood ignited at 420 ° C (ignition risk temperature 250 ° C) (burning speed is 18mm in 30 minutes), and then carbonized on the surface The layer plays the role of a heat insulating material, suppresses the temperature rise inside the wood and prevents the generation of combustible gas generated by thermal decomposition, so it becomes harder to burn. In addition, incombustible treatment of solid wood is also possible.

Solid wood driven formwork is not dismantled, so the precision of the formwork is high and strong, so electrical wiring and equipment can be installed in parallel with the formwork, and piping sleeves for water supply and drainage equipment need to be inserted This pipe can be made without any problems. For this reason, useless materials and construction costs are unnecessary, and each equipment cost can be greatly reduced.

As described above, the driving form of the present invention can be used for a driving form even if it is made of various materials and shapes. In addition, the connection of the driving molds can be performed in a staggered manner in which the connection joints are not linearly connected, or in the above-described method by connecting the connection joints vertically. In that case, there is no problem in workability even if the driving mold 1 is short.

The driving form of the present invention is a flooring shape with an appropriate width, so that it is easy to process and construct, and is easy to organize and transport.

Today, where global warming is a concern, making the outer wall of the structure into a solid wood-working formwork will contribute to the prevention of global warming by creating a structure that is friendly to the global environment that does not reflect solar heat. In addition, by using domestic timber as the placement formwork, it can contribute to the activation of forest depopulated areas and the conservation of forests.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view for explaining a state in which the driving mold 1 and the connecting member 6 and the lattice member 10 are connected to each other according to the present invention. FIG. 2 is a detailed rectangular cross-sectional view of a structure for explaining an embodiment of the case, and FIGS. 3 to 17 are detailed views of vertical and horizontal cross-sections of the case, the driving form and the connecting member, and the shape of each connecting member. Is.

Since the outer wall of the building is required to be insulated, it is necessary to select a placement form that has heat insulation performance or a placement form that is equipped with a heat insulating material. FIGS. 1 to 3 and FIG. The solid wood placement form that I had was selected. The solid wood driving form 1 has an appropriate floor width in the form of a flooring, is provided with a hiring actual insertion groove 3 and a plurality of connecting member insertion holes 2 on the side of the connecting portion, and inserts the hiring actual member 4 and the connecting member 6. Connect and fix with screws 8.

By inserting and connecting the hiring member 4 into the hiring actual insertion groove 3 on the side of the connecting portion of the driving form 1, leakage due to the placement of the concrete 15 can be prevented and the strength of the connecting portion is increased. The material of the employed actual member 4 can be appropriately selected and used, such as iron, non-ferrous metal, resin, and wood.

Since the solid wood casting form 1 is expanded by placing concrete 15, the decorative surface is spaced apart from the expected expansion interval as shown in FIG. 14, and the back surface is generated by the thickness of the connecting member 6. The cushion material 5 shown in FIG. 1 is attached to the gap. The connecting member 6 is ignored because it does not affect the expansion.

For connecting and fixing the driving form 1 inside and outside the wall, the cylindrical protrusion 6a of the connecting member 6 having a screw hole 7 formed in the notched cylindrical protrusion 6a at which both ends of the fixing part can be inserted is inserted into the mold form. 1 is inserted into a connecting member insertion hole 2 provided on the side surface of the connecting portion, and is fixedly connected to the adjacent driving form 1 with screws 8.

By connecting and fixing, the plurality of driving molds 1 become a single plate, and a strong driving mold can be constructed. As shown in FIGS. 1 and 2, by attaching a hook-shaped lattice member 9 to the connecting member 6 having the lattice holes 10 formed at both ends in order to make the strong driving form body stronger. The driving mold 1 and the connecting member 6 and the lattice member 9 are integrated, so that the entire driving mold has a truss shape and becomes strong. As for both end flanges of the lattice member 9, those obtained by processing the drop-off preventing ribs 9 a shown in FIG. 13 are used. In addition, the lattice member 9 is attached at a place necessary for strength.

The connecting member 6 having the lattice holes 10 at both ends can be used for various types of connections. For example, when one of the driving molds 1 is a mold 24 to be dismantled, a mold for disassembling by a conventional method by attaching a round separator 25 to the lattice hole 10 on the driving mold 1 side of the connecting member 6. The frame 24 can also be connected. See FIGS.

Since the connecting member 6 and the lattice member 9 for connecting and fixing the driving form 1 are required to be a material having a strong tension capable of withstanding the concrete placement side pressure, a resin with good workability is desirable. Can also be used.

The plate thickness of the driving mold 1 is set to a thickness that can withstand the concrete pouring side pressure. However, since the screw 8 penetrates the cross section of the connecting portion of the driving mold 1, the driving mold 1 is stronger due to the tension of the screw 8. Increase. Therefore, the lateral strength of the driving mold 1 can be increased by screwing the screws 8 at appropriate intervals other than the connecting portion of the driving mold 1.

In the present invention, the placement mold 1 is selected from materials satisfying many conditions such as strength capable of withstanding concrete placing side pressure, durability, workability, and clothes, but it is particularly important to have heat insulation performance. And wood is the best material. However, there are structures that are not suitable for wood, and when it is necessary to cope with a fire, there is a case where a driving form 1 fitted with a heat insulating material using an inorganic material having fire resistance and fire prevention performance such as ceramic materials is sometimes used. . Further, there is a case where a fireproof material is attached to the decorative surface of the solid wood placing mold 1 or the solid wood placing mold 1 which has been subjected to non-combustion treatment is used.

In addition, as for the placement mold 1 in a region such as a cold region, when using a solid wood placement mold 1 with a heat insulating material, or increasing the thickness of the solid wood placement form 1 Can also respond.

As described above, the types of driving molds 1 that can be used in the present invention are solid wood driving molds 1 described in FIGS. 3 and 5, solid wooden driving molds 1 with insulating materials described in FIGS. Inorganic material casting mold 1 described in FIGS. 3 and 5; Inorganic molding material in which a heat insulating material is attached 1 FIG. 6 and 8; those having a decorative material attached to the casting mold 1; A wide variety of driving molds 1 such as engraved ones and colored ones can be used.

The connection method of the driving mold 1 according to the present invention does not use a temporary material for constructing a wall of a structure, and therefore can be easily connected regardless of any irregularities or patterns on the surface of the driving mold 1. Also, it will not break during construction.

In all the drawings, the driving form 1 is connected in the vertical direction, but the present invention can also be used in the horizontal direction. For example, a staggered connection in which the connection joints are not linearly connected, or the connection by the above-described construction method can be made by connecting the connection joints vertically. In that case, there is no problem in workability even if the driving mold 1 is short.

The above is suitable for construction of civil engineering retaining walls and handrails. In addition, covering the concrete frame of the structure with the driving mold 1 increases the useful life of the concrete.

The construction form and connection method of the structure of the present invention have been described above. Next, the construction form and connection method related to the scissors will be described.

Explaining the embodiment of the board fence based on FIGS. 9 to 11, many board fences have been conventionally produced, but there are many problems such as high cost and corrosion, and today, decorative block fences and fence fences are used for tributaries. Has been. However, there are many people who are eager for earthen wood or solid wood boards. In view of that, the present invention is provided. As shown in FIG. 11, the casting mold 1 with the lower part scraped off on the fabric foundation 23 is widened to expand the surface of the fabric foundation 23 as shown in FIG. 9. As for the connection of the frame 1, the above-mentioned hired actual member 4 and the connection member 6 are used to connect and fix with the screws 8 as described above to form a driving-type frame body, and concrete 15 is placed to construct a plate cage.

The soot constructed in this way is finished with metal heads, non-ferrous metal heads, wood heads, tile heads, etc. Moreover, since the board fence of the present invention is strong, a conventional heavy tile roof can be constructed. In this way, it is possible to construct a wide variety of board and earthenware.

Referring to FIG. 2, an embodiment of a small-scale building of about three floors will be described. The driving form 1 on the inner wall is screwed to the solid foundation 13 and the fixed large pull 12 fixed to the second and third floor slab forms 17. 8 is fixed by the above-mentioned connecting method, and the temporary beam receiver 19 is temporarily fixed to the upper portion of the built-in mold 1 on the inner wall, the temporary beam 18 is placed, and the slab form 17 is firmly fixed. Fix it. The temporary construction of the slab formwork 17 support may be supported by a conventional steel post, but the former is desirable in order to allow continued work in small buildings.

After fixing the above-described inner form 1 and the slab form 17, the rebar 14 is assembled and the external form 1 is built and connected. Repeating this work completes the formwork and rebar assembly on all three floors, and completes the placement of concrete on all three floors in one day. The driving form 1 of the present invention can be connected in a single plate shape, and the driving form 1 inside and outside the wall can be constituted by a connecting member 6 and a lattice member 9 to form a truss in the wall. Become a body. This truss can be configured at a position necessary for strength.

In this embodiment, solid wood is used as the material of the driving form 1, so that the driving form 1 inside and outside the wall becomes a heat insulating material inside and outside the wall, and it is not necessary to install a heat insulating material in a warm region. In addition, since the solid wood driving form 1 can be used as a finishing material inside and outside the wall, neither a finishing material nor finishing work is required. When finishing other than that of solid wood is required, a wide variety of finishes can be easily made using the solid wood driving form 1 as the base body edge.

The structure constructed with the driving form 1 of the present invention is to cover the concrete frame with the driving form 1, and the solid wood driving form 1 becomes a concrete curing material, and the structure has a surprisingly long service life. Become. A long service life is accompanied by repairs, but a wide variety of repairs are easy with the solid wood driving form 1 as the base barrel edge.

There are various conditions in the formwork of the structure. As an example, there is a case where one side needs to be decorated and the other side must be disassembled like a retaining wall. 15 and 17, one side is used as the driving form 1 of the present invention, and the other side is disassembled with a temporary form material 24 (such as a veneer formwork). With a connecting member (see FIG. 16) in which the round separator 25 is fixed to the member 6, the concrete 15 is placed by being connected, and after drying, the veneer formwork is disassembled to construct a retaining wall. The connecting member described here indicates that the connecting member 6 of the present invention can be used, and workability is better if the connecting member conforms to this construction method.
