BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a shear wall structure. More specifically, the present invention relates to a quake-resistant wall structure using fastening hardware with good workability as a means for fixing wall reinforcing bars.

[Conventional technology and its issues] Along with trends such as the rise in the height of buildings and the increasing social demand for earthquake countermeasures, various ideas and improvements have been made to earthquake-resistant structures. There is a strong need to realize architectural structures with improved safety and safety. For example, previous earthquake disaster research has reported that reinforced concrete buildings with shear walls have superior seismic performance and are less susceptible to damage from earthquakes than structures consisting only of columns and beams.

[0003] From this point of view as well, studies have been made on the structure of buildings having earthquake-resistant walls, and various ideas and improvements have been made. Normally, when constructing such a seismic wall, reinforcing bars made of steel are provided in the wall plate. Although this shear wall has the above-mentioned structural advantages, conventional construction methods require carrying long reinforcing bars into the site and placing them one layer at a time, which is a very labor-intensive process. This has become an issue that needs to be improved, especially in light of the recent shortage of reinforcing bar workers.

[0004] Therefore, in order to save labor in reinforcing steel work, it has been seen as promising to use a welded wire mesh, which is welded in a lattice shape in advance, as reinforcing bars for wall plates. However, when using this welded wire mesh as reinforcing bars for shear walls, a major issue is how to fix it to the side columns and side beams, and until now, there has been no effective method for fixing it. The reality is that it has not been discovered.

The present invention was made in view of the above circumstances, and provides a new welded wire mesh that can save labor in installing wall reinforcing bars and also has excellent reinforcing performance. The aim is to provide an improved shear wall structure with an anchoring method.

[0006]

[Means for Solving the Problems] The present invention solves the above-mentioned problems by using a deformed bar steel as a fixing bar for fixing the welded wire mesh wall reinforcing bar of a seismic wall and a side column/side beam.
To provide a shear wall structure in which a fixing method with good workability is realized by an indirect fixing method in which connecting bars are welded in a comb shape made of round steel or deformed steel bars and overlapped with the periphery of a welded wire mesh.

[0007] In this structure, since comb-shaped welded reinforcing bars are used as fixing hardware to the side columns and side beams, welded wire mesh can be overlapped with each other at the overlap length of the overlap joint of the welded wire mesh, as stipulated by the Society's RC standards. , the welded wire mesh as wall reinforcement can be sufficiently fixed. As a result, a new earthquake-resistant wall can be realized that not only has earthquake-resistant performance but also has excellent anchorage reinforcement workability.

The present invention will now be described in more detail with reference to FIG. 1 of the attached drawings. This FIG. An example of fixation using . This makes it easy to fix to the side pillars (3) and side beams (4), and to provide the required seismic resistance. Furthermore, since this anchoring method is an indirect anchoring method, even if the concrete for the shear wall and the side beams are poured separately, the workability of beam reinforcement will not be deteriorated by the anchoring hardware. That is, after pouring concrete for the wall up to the pouring surface (A) in FIG. 1, the anchoring hardware can be placed together with the beam reinforcement.

As shown in FIG. 2, the anchorage bars (5) are made of deformed steel bars, and the connecting bars (6) are made of round steel or deformed steel bars, welded in a comb shape. . In addition, although the 45 degree diagonal welded wire mesh (1) is illustrated as a wall reinforcement in the above example, it is not limited to this. It may be vertically and horizontally welded wire mesh, or diagonally welded wire mesh at various angles.
