Description

Seismic reinforcement device of brick walls using omega horizontal rebar and jointing locking member and construction method using of the same}

The present invention relates to a brick wall seismic reinforcing device and a construction method of a brick wall using the same, in particular, by allowing the brick wall to behave integrally with a support structure, preventing cracks of the brick wall in advance, and applying a horizontal level to the brick wall It relates to a seismic strengthening device for a brick wall through omega horizontal roots and joint locking materials that can effectively prevent seismic forces from being distributed to a support structure and to prevent the collapse and collapse of a brick wall during an earthquake, and a method for constructing a brick wall using the same.

Examples of masonry structures include schools, religious facilities, and government offices. Since these masonry structures are used as non-structural elements, it is necessary to prepare concrete measures for horizontal forces such as earthquakes and to develop earthquake-proof reinforcement methods, as economic damages as well as human damage can occur due to major damage in the event of an earthquake. As a typical reinforcing method example of a masonry structure, it is a method of drilling holes in a masonry wall and fixing it with bolts and iron plate nuts, a construction method of adding steel frames, and vibrating the wall by cutting the joints of the masonry wall at the location of concrete beams. However, a concrete cantilever-type reinforcement bracket construction method (impossible to have beams) and a method using a stainless screw-type reinforcement pin are known.

In the case of a masonry wall, when vibration or earthquake occurs, cracking, sliding, and dropping may occur due to loss of bonding strength with a supporting structure such as a connected reinforced concrete bearing wall, which can cause serious human and property damage. Solutions are required.

As a background technology of the present invention, Korean Patent Registration No. 10-1544153 discloses a system for fixing the outer wall of a building. This is to prevent the occurrence of cracks in the outer brick wall due to the load distribution by the expansion joint, and to ensure that the outer brick wall is stably fixed to the bearing wall, and is installed horizontally between masonry bricks to crack the outer brick wall. Expansion joints to prevent this from occurring; It is installed on the bearing wall so as to be located on the upper portion of the expansion joint, and is attached to the bearing wall fixed to the bearing wall, and vertically protrudes in the direction of the outer brick wall from both ends of the mounting plate, sandwiched between the sides of the masonry bricks and installed in the horizontal A plurality of brick support brackets configured to include the formed base plate and installed to have mutually spaced structures on the bearing wall; It is configured to include; it is installed so that both ends fit into the installation hole of the adjacent brick support bracket to support the masonry brick placed on the top of the expansion joint to prevent the transfer of load to the expansion joint.

However, in the former background technology, the wing pin included in the anchor member for fixing the brick is installed to be rotatable on the fixture, so that the horizontal construction of the connecting tie is easy, whereas when the horizontal earthquake occurs, the anchor member for fixing the brick cannot do torsion resistance. A stable structure of brick walls cannot be secured.

As another background technology of the present invention, Korean Patent Registration No. 10-1641015, a 'brick support structure device and construction method thereof' has been proposed. This includes an angle including a vertical plate in which bricks are masonry and supports a load of the masonry bricks and a plurality of first catching slots bent in a direction perpendicular to the horizontal plate and formed in a vertical direction; And a bracket having a coupling plate detachably coupled to the bearing wall and a vertical support plate that is bent at a right angle from the side of the coupling plate and is formed to be coupled to the first locking slot at an end thereof. It is not necessary to use a release brick for brick masonry at all, and it is commonly used regardless of the size of all bricks, and it can be configured to be freely adjustable to install an adjacent brick. However, in the latter background technology, when a horizontal seismic force occurs, there is no means to share the force transmitted to the bracket, and the anchor member is deformed, which may cause cracking, sliding and dropping of the masonry wall.

The brick wall seismic reinforcement device according to the present embodiment is provided with a fixed angle hardware 14 fixed to the support structure 100 with anchor bolts 13 as shown in FIGS. 1 to 3. The fixed angle hardware 14 has an L-shaped anchor bolt insertion hole 141 at one end, and a titanium steel insertion hole 142 or 142 for connecting a U-ring tie hardware 18 to be described later to the other end. It is preferable that the inserting holes 142 and 142 are formed into long holes in consideration of the installation movement of the U-ring tie-irons 18.

The omega horizontal muscle 16 has a structure in which the S-shape is repeated over a certain length. Omega horizontal muscle 16 is made of steel wire in this embodiment, but is not limited to such a steel wire material. The omega horizontal muscle 16 is disposed on the horizontal joint of the brick wall 1 corresponding to the height at which the fixed angle hardware 14 is located as shown in FIG. 5A and is synthesized in mortar. Therefore, the omega horizontal root 16 transmits the horizontal seismic force of the brick wall 1 upon the arrival of the earthquake to the fixed angle hardware 14 via the U-ring tie hardware 18. In addition, the omega horizontal muscle 16 prevents the collapse of the brick wall 1 while performing an integral behavior according to the in-plane deformation (lateral deformation) of the brick wall 1 when the earthquake arrives while connected to the U-ring tie-iron 18 do.

The U-ring tie steel 18 has a vertical bridge 182 and 182 with an intersecting bridge 181 and an end.

The U-ring tie hardware 18 generates rotational resistance to the brick wall 1 upon the arrival of an earthquake and at the same time transmits the horizontal seismic force to the fixed angle hardware 14. In addition, the U-ring tie hardware 18, when the brick wall 1 is subjected to wind load, resists through the fixed-angle hardware 14 to prevent the brick wall 1 from falling off and collapsing.

A Z-shaped joint locking material 22 disposed on the bottom surface of the omega horizontal muscle 16 is provided. The Z-shaped joint locking material 22 is connected to the U-ring tie iron 18 with a hole 22a and is installed in the vertical joint and horizontal joint of the brick wall 1. The Z-shaped joint locking material 22 may be made of iron plate or steel plate. The Z-shaped joint locking material 22 is a vertical plate 221, an upper horizontal plate 222 bent in a direction perpendicular to the upper end of the vertical plate 221, and a lower end of the vertical plate 221 bent in the other right angle direction. It may be composed of a lower horizontal plate (223). At this time, the vertical plate 221, the upper horizontal plate 222 and the lower horizontal plate 223 are formed with a plurality of holes 22a penetrated in the thickness direction, respectively.

On the other hand, the present invention may be further provided with a reverse omega horizontal muscle (16a) is installed on the horizontal joint of the brick wall (1), the omega horizontal muscle 16 is disposed as shown in Figures 3 and 4. The reverse omega horizontal muscle 16a intersects the omega horizontal muscle 16 so that a ring-shaped closed structure that captures both ends of the U-ring tie-iron 18 appears. The reverse omega horizontal muscle 16a has a relatively small length and a repetitive S-shape structure than the omega horizontal muscle 16.

In addition, a U-shaped coupling locking bar 24 inserted into the omega horizontal muscle 16 and the Z-shaped joint locking material 22 may be further provided.
