Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more particularly, relates to a concrete module integrated with a prefabricated shear wall and an assembly method thereof. Background Art

[0002] With the rapid development of the construction industry and the rapid advancement of urban modernization, traditional construction methods can no longer meet the demands of modern construction speeds. Consequently, prefabricated building methods have emerged. These methods divide buildings into multiple independent wall panels, which are prefabricated in factories and then transported to the construction site for assembly to form a complete building. When prefabricated buildings are used on-site, the joints between the wall panels are often unstable, prone to deformation and cracking, resulting in unsightly walls and even potential dangers.

[0003] Existing prefabricated buildings include prefabricated wall panels, and the steel bars in the prefabricated wall panels are installed with connecting sleeves. When two adjacent prefabricated wall panels are assembled, the multiple sleeves in the upper prefabricated wall panel cannot be completely aligned with the multiple steel bars in the lower prefabricated wall panel due to slight deviation of the steel bars in the prefabricated wall panel or the sleeve. As a result, the steel bars in the lower prefabricated wall panel cannot enter the sleeves of the upper prefabricated wall panel for connection and fixation. Therefore, the construction of the prefabricated wall panels is difficult and inefficient. In addition, after the steel bars in the lower prefabricated wall panel are inserted into the sleeves, slurry needs to be poured into the sleeves. Misalignment between the sleeves and the steel bars will result in the slurry not being fully filled in the sleeves. In addition, the raw materials of the slurry have high requirements, the cost is expensive, the ratio is difficult to control, and the grouting is difficult to fully fill. Space is often left, which makes the slurry easy to age and crush, causing the steel bars to loosen and the structural strength to decrease, thereby affecting the quality of the building.

[0004] Therefore, a concrete module with integrated prefabricated shear walls is needed to further subdivide the building assembly process into modules. After ensuring the assembly quality of each subdivided module, the overall building can be assembled to enhance the building's molding effect and reduce the probability of building problems. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a concrete module and assembly method for integrated prefabricated shear walls, which further subdivides the assembly process of the building into modules, ensures the assembly quality of each subdivided module, and then assembles the entire building. The concrete pouring and prefabrication of part of the wall of each component of the concrete MiC module is completed in the factory, and after prefabrication, it is transported to the site, and the cast-in-place concrete is used to fix it with the structure on the construction site, reducing the use of on-site formwork and the workload of on-site steel bar binding, greatly improving on-site construction efficiency.

It is manufactured in a factory by pouring concrete on the ALC board. The light steel frame partition wall 501 is arranged inside the concrete MiC module to divide the space inside the concrete MiC module.

A post-cast plate is also provided above the top plate 3. This post-cast plate further reinforces the cast-in-place concrete 6 and the top plate 3, strengthening the connection and fixation of the cast-in-place concrete 6 to the upper and lower concrete MiC modules.
