At present, shear wall reinforcing members in most buildings are still realized by adopting traditional technologies such as screw rods, nuts and the like, when the reinforcing members are used for reinforcing, the screw rods are firstly inserted into frames prefabricated by the shear walls, two ends of the screw rods are respectively positioned at two sides of the frames prefabricated by the shear walls, then fasteners are respectively penetrated into two ends of the screw rods, finally bolts are installed at two ends of the screw rods, the bolts at two ends are inwards screwed in and tightly attached to the fasteners, the fasteners are tightly attached to the frames prefabricated by the shear walls, and therefore the reinforcing members of the frames prefabricated by the shear walls are realized. However, the whole installation and disassembly of the shear wall reinforcing member are slow due to the adoption of a bolt and nut reinforcing mode, and the construction progress is influenced; in addition, the nut is easy to slip under the condition of compression, so that in the process of filling concrete into the prefabricated frame of the shear wall, the nut is separated from the original fixed position, accidents such as mold explosion, concrete over-square and the like occur, and the construction difficulty is increased.
In the prior art, shear wall reinforcing members for reinforcing a shear wall prefabricated frame have appeared, which include one tie rod, two fasteners and two bolts. When the clamping device is used, the pull rod is inserted into the shear wall prefabricated frame firstly, then the fasteners are installed at the two ends of the pull rod respectively, the two fasteners are buckled on the frames on the two sides of the shear wall respectively, finally the bolts are clamped on the outer sides of the two fasteners at the two ends of the pull rod respectively, the two bolts enable the pull rod fasteners to be attached to the shear wall prefabricated frame tightly, and the pull rod fasteners at the two ends of the pull rod form clamping spaces for the shear wall relatively.
However, in the prior art, the column-shaped rod of the shear wall reinforcement penetrating into the shear wall prefabricated frame through the pull rod is set to be cylindrical, and in the using process, if the column-shaped rod is directly penetrated into the shear wall prefabricated frame, the column-shaped rod is not easy to take out after the concrete is solidified, or the risk of breakage of the pull rod is very easy to occur in the taking-out process. In order to avoid the problem that the pull rod is difficult to take out, a wall bushing is sleeved on the outer side of the columnar rod in a movable mode, then the wall bushing and the columnar rod are arranged in the prefabricated frame of the shear wall in a penetrating mode, after concrete pouring is completed, the concrete is solidified, the wall bushing is fixed in the concrete, and finally the end portion of the columnar rod is hammered through a hammer, so that the pull rod is integrally hammered out from the concrete. In the process, the wall bushing for installation is difficult to take out and is inevitably arranged in the concrete for a long time, so that a plurality of wall bushings are required to be utilized in the construction process, and the construction cost is high.
