部分を打ち増すのに労力を要し、材料費も嵩む。When the seismic wall is eccentrically joined, the yield strength is expected to be lower than when the seismic wall is not eccentric. In the case of the former, it takes a labor to add the reinforced concrete portion to the steel frame beam, and the material cost also increases.

The present invention has been proposed in view of the problems of the above-mentioned prior art, and the object thereof is to shorten the construction period, improve the reliability of the joint portion, and increase the horizontal width without increasing the beam width. The purpose of the present invention is to provide a horizontal joining method for precast concrete earthquake-resistant walls with steel beams that facilitates joining of joints.

リートの充填性がよくなる。According to the present invention, as described above, the beam steel frame of the precast concrete earthquake-resistant wall with steel beam is divided into two,
Since each of the divided beam steel frames is preliminarily joined to the PCa earthquake-resistant wall, and horizontal joining at the site is performed only by the beam steel frame, stress from the upper and lower wall reinforcements can be transmitted through the beam. Thus, since the beam steel frames are joined together, no curing is required after the joining, and according to the present invention, the concrete portion and the beam reinforcing bar portions are pre-joined to the beam steel frames at the factory, so that the filling property of concrete is improved. .

FIG. 1 and FIG. 2 show a first embodiment of the present invention, in which a joining steel plate 1b projecting from a base end flange 1a of a beam steel frame 1 having an H-shaped cross section obtained by horizontally dividing the beam steel frame into two parts is used. After welding the large-diameter wall rebars 2 and integrally manufacturing the PCa earthquake-resistant wall 4 with a beam including the large-diameter wall rebars 2 and the small-diameter wall rebars 3 with the flange 1a, after erection of the column, ) As shown in (b), the PCa earthquake resistant wall with beams 4 is erected, and the tip flanges 1c, 1c of the split beam steel frames 1 are struck at the joints 5 in the opposing PCa earthquake resistant walls with beams 4. As shown in FIG. 5C, the bolts 6, rivets, etc. are passed through the flanges 1c, 1c, and the nut 7 is screwed and tightened to join the both PCa earthquake-resistant walls 4.

よって壁のすべりが抑制される。According to the present invention, as described above, the beam steel frame is divided into two in the horizontal direction, and each of the divided beam steel beams is divided into PCa.
Since it is joined to the earthquake-resistant wall and horizontal joining at the site is performed only by the beam steel frame, curing after joining is unnecessary, workability is improved, construction period is shortened, and joint reliability is improved. However, the joining work of the horizontal joining portion is easy. Further, since the concrete portion and the beam reinforcing bar portion are pre-joined to the beam steel frame at the factory, the concrete filling property is improved. Furthermore, the beam rebar joined to the beam steel frame by welding or the like restrains the expansion of the frame, and the wall slip is suppressed by the dowel action of the wall rebar.
