One end of the first leaf plate precast beam longitudinal reinforcement 112 and the first leaf plate horizontal stirrup 111 extends into the first leaf plate edge member notch 114.

[0049] See Figure 8 The first leaf plate shell mold 120 includes a first leaf plate edge component shell mold 122, a first leaf plate wall shell mold 123, a first leaf plate beam shell mold 124, and a first leaf plate structural column 125. The first leaf plate edge component shell mold 122, the first leaf plate wall shell mold 123, and the first leaf plate beam shell mold 124 are all embedded with first leaf plate precast wall horizontal reinforcement 126 and first leaf plate precast wall longitudinal reinforcement 127.

[0051] See Figure 11 The second leaf plate shell mold 220 includes a second leaf plate edge component shell mold 222, a second leaf plate wall shell mold 223, a second leaf plate beam shell mold 224, and a second leaf plate structural column 225.

By installing back ribs on the inner side of the module, the rigidity of the shell membrane can be increased, ensuring that the shell membrane will not crack or deform during the transportation of the module. At the same time, it can also prevent the shell membrane from bursting when pouring concrete on the construction site. The back ribs can be removed and recycled after the concrete has been poured and solidified.

[0059] In other embodiments, steel reinforcement connecting rings in other directions can also be provided, such as steel reinforcement connecting rings in both horizontal and vertical directions simultaneously. This application does not limit the scope of these embodiments. Those skilled in the art can determine the direction of the wall steel reinforcement connecting rings according to actual needs. In practical engineering, the second embodiment is... Figure 12 The vertical wall reinforcement connecting ring shown is relative to the first embodiment, i.e. Figure 1 The horizontal wall reinforcement connecting rings shown are easier to install and have stronger shear resistance.

[0060] See Figure 23This application also provides a building in which the interior partition walls are composite shear walls as described in any of the above embodiments.

[0061] In one embodiment, the building includes at least two room modules, and the internal partition wall between the left and right adjacent first room modules and second room modules is set as the composite shear wall.

[0062] In one embodiment, the building includes at least two floors. The top of the composite shear wall of the lower floor is provided with reinforcing bars, and the bottom of the composite shear wall of the upper floor has a groove extending along the length of the wall, into which the reinforcing bars are inserted. The composite shear walls of the upper and lower floors are joined together by pouring concrete into the cavity.

[0063] In conjunction with the aforementioned buildings, this application also proposes an adapted construction method for buildings, comprising the following steps:

[0064] During the prefabrication of the first leaf slab, concrete is poured in the factory to form the first room module with the surrounding walls; during the prefabrication of the second leaf slab, concrete is poured in the factory to form the second room module with the surrounding walls.

[0065] A first back rib 12c is installed on the inner side of the first leaf plate of the first room module. The first back rib 12c is connected to the first pre-embedded bolt sleeve 12a on the first module through the first connecting bolt 12b. A second back rib 22c is installed on the inner side of the second leaf plate of the second room module. The second back rib 22c is connected to the second pre-embedded bolt sleeve 22a on the second module through the second connecting bolt 22b.

[0066] Transport the required room modules to the construction site;

[0067] First, the first room module is hoisted and lowered from top to bottom until it is in place; then the second room module is hoisted and lowered from top to bottom until it is in place.

[0068] At the construction site, connecting stirrups 300 are used to connect the horizontal stirrups 111 of the first leaf plate and the horizontal stirrups 211 of the second leaf plate, and the first wall steel reinforcement connecting ring 121 and the second wall steel reinforcement connecting ring 221 are anchored to each other; and longitudinal steel bars 400 are set in the cavity.

[0069] Templates are installed on the outer sides of the first blade edge member 110 and the second blade edge member 210 to seal the open parts of the cavity;

[0070] At the construction site, concrete is poured into the cavity;

[0071] After the concrete has hardened, remove all back bracing and formwork.

[0072] In summary, the composite shear wall of this embodiment allows the first and second leaf plates to be separated into two adjacent room modules. After the two modules are poured with concrete on site, they form a complete T-shaped edge member. This method does not increase the thickness of the wall edge member, facilitates on-site reinforcement placement, and effectively connects the precast and cast-in-place parts through pre-reserved horizontal stirrups in the precast part, making the composite shear wall a complete whole. Compared with cast-in-place components, it does not affect its load-bearing performance.

[0073] This embodiment proposes a prefabricated shear wall assembly form, which splits the wall components into two shell-like leaf-shaped components. Both components have horizontal stirrups and steel reinforcement connecting rings for the shear wall. The truss reinforcement or connectors of the double-sided composite shear wall are replaced by horizontal stirrups and steel reinforcement connecting rings. After the two components are assembled, a cavity for post-cast concrete is formed in the middle. After the concrete is poured into the cavity, the horizontal stirrups of the two components form effective tensile force after the concrete sets, so that the two components can be effectively combined into a complete shear wall body.

[0074] Reinforcing bars can be pre-installed at the top of the lower precast shear wall, and grooves extending along the length of the wall are opened at the bottom of the upper shear wall. After the reinforcing bars are inserted into the grooves, the two floors can be combined by pouring concrete into the cavity of the wall. This method does not increase the thickness of the shear wall, eliminates the need for longitudinal connecting bars and formwork on the construction site, and results in high wall installation efficiency, reliable quality, and improved on-site assembly efficiency.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
