Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a combined prefabricated installation wall. Background Art
[0002] Precast concrete wall is a kind of concrete wall component produced by factory prefabrication. This kind of wall component is made in the factory through a precisely controlled production process, and has the characteristics of standardization, high precision and high quality. Precast concrete wall is mainly composed of concrete, steel bars and other auxiliary materials. After mold forming, curing and other processes, it is transported to the construction site for assembly.
[0003] The utility model with the authorization publication number CN217896994U provides a precast concrete wall, which belongs to the technical field of "construction engineering" and the protected claim: "including a first concrete layer, a through-type steel bar is arranged inside the first concrete layer, the first concrete layer is fixedly connected to an insulation layer on the side, a cement foam insulation board is arranged inside the insulation layer, the insulation layer is fixedly connected to a second concrete layer away from the first concrete layer, a groove is arranged inside the second concrete layer, a connecting block is fixedly arranged on the upper surface of the second concrete layer, a through hole is arranged inside the connecting block, the second concrete layer is fixedly connected to a third concrete layer on the side away from the insulation layer, and the surface of the third concrete layer is fixedly connected to a waterproof layer on the side".
[0004] In this device, although the connection and fixing effect is achieved by adding steel bars on the upper and lower parts, and triangular reinforcement bars are also installed, the triangular reinforcement bars of this device only act on the second concrete layer, not on the whole. The steel bars added on the upper and lower parts also only act on the first and third concrete layers, not on the whole. Moreover, there is no transverse fixed connection between the layer plates, especially there is no effective connection between the internal insulation layer and the concrete layers on both sides. Because there is no overall reinforcement, the shear resistance of the wall will be significantly reduced. In short, since there is no effective reinforcement measure for the whole device, when subjected to shear force, the wall is prone to stratification damage. For this reason, we propose a combined prefabricated installation wall. Utility Model Content

[0028] During specific implementation, the steel cables 34 in the two groups of traction assemblies 3 are stretched and passed through the corresponding first traction plates 5 and second traction plates 6, and then the fastening bolts 8 are tightened. In this process, the steel cables 34 are tightened, and the connecting rod 33 is pulled. The pulling of the connecting rod 33 will drive the first rotating rod 32 and the second rotating rod 35 to rotate, and then drive the first slider 31 and the second slider 36 to slide in the sliding groove 4. The first slider 31 and the second slider 36 slide in the sliding groove 4, which will drive the first plate body 1 and the second plate body 2 to move toward the middle. After the steel cables 34 in the two groups of multiple traction assemblies 3 are tightened by the fastening bolts 8, the first plate body 1 and the second plate body 2 can be tightened by pulling to make them a whole and not easy to separate.
[0029] like Figure 2 As shown, further, the number of traction components 3 is set to two groups, the number of traction components 3 in each group is set to multiple, and the two groups of traction components 3 are arranged opposite to each other.
[0030] In specific implementation, the stretching and tensioning effect can be improved by providing two sets of opposite traction components 3 .
[0031] like Figure 2-3 As shown, further, the inner ends of the two groups of first sliders 31 and the second sliders 36 are respectively fixedly connected with rod bodies 37, and springs 38 are sleeved on the outside of the two groups of rod bodies 37; multiple slide grooves 4 are opened on the inner sides of the first plate body 1 and the second plate body 2, and the two groups of slide grooves 4 are arranged opposite to each other, and one end of the two groups of rod bodies 37 is telescopically connected in the slide groove 4.
[0032] In a specific implementation, the first slider 31 and the second slider 36 are driven to move in the slide groove 4, and the rod body 37 is subsequently extended and retracted in the slide groove 4.
