Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a quick-assembly and reusable prefabricated modular housing structure and its construction method. Background Technology

[0002] Currently, there are four types of modular housing: prefabricated houses, packaged houses, solid PC module houses, simple PC module houses, and light steel module houses.

[0025] Compared with the prior art, the present invention has the following features and beneficial effects.

[0026] 1. This invention relates to a prefabricated modular housing structure that can be quickly installed and reused repeatedly. This prefabricated modular housing structure enables the house to be manufactured in a factory using standardized, modular, and universal production. The house can be assembled on-site anytime and anywhere, and the entire process can be completed in just a few hours. The modular integrated building is easy to transport, install, dismantle, and reuse.

[0027] 1. The quick-assembly and reusable prefabricated modular housing structure of the present invention has the characteristics of being lightweight and high-strength, having good thermal insulation, long service life, high turnover rate, good thermal insulation and energy-saving effect, and excellent living experience. It can solve the technical defects related to current modular housing. Furthermore, the invention can achieve standardization and realize efficient and rapid on-site installation.

[0028] 2. The wall panel of the present invention is provided with ribs, which can increase the bending load capacity and overall strength of the panel; in addition, the presence of ribs can distribute the load force acting on the wall panel, thereby improving the overall stress performance of the wall panel by increasing the stiffness and stability of the wall panel.

[0029] 3. The present invention embeds strip-shaped timber in the ribs, which can increase the overall strength of the concrete slab; by tightly integrating the timber with the concrete slab, it provides additional support and reinforcement in the transverse and longitudinal directions, thereby increasing the load-bearing capacity of the concrete slab and making it more robust and durable; in addition, the setting of the strip-shaped timber avoids direct drilling into the concrete slab, which would cause damage such as concrete cracking, and facilitates the connection between adjacent slabs.

[0030] 4. This invention changes the traditional box-type bolt connection to a rib-type bolt connection, eliminating the need for setting up and pre-embedding the connection box, which is more economical.

[0031] 5. In this invention, the vertical and horizontal ribs on the wall panel together form a concave cavity, and no formwork is needed for later filling with concrete; and when pouring concrete, the cavities of the two walls can be temporarily fixed with bolts, which can reduce the need for support.

[0032] 6. This invention installs wire ropes and anchor rings on the sides of the wall panel units on both sides of the splicing joint. Both the wire ropes and horizontal sleeves are pre-embedded in the wall panels. Because the wire ropes are relatively soft and the anchor rings are relatively hard, the combination of these two materials fully utilizes their advantages. If ropes are used at both ends, their softness can cause them to sag if the pre-existing length is too long, hindering the connection between the two walls. If rings are used on both sides, their hardness can lead to misalignment and a loose connection during installation, requiring high precision and hindering construction. Furthermore, the rings cannot deform during the hoisting of the last wall panel unit, as this would impede its descent. This invention, using ropes and anchor rings, reduces the number of bolt connections. Simultaneously, the constraint effect of the anchor rings and rope openings ensures the effectiveness of the vertical wall connection. Additionally, during anchor ring production, only a horizontal sleeve needs to be pre-embedded in the wall for direct connection, facilitating factory production.

[0033] 7. The waterproof structure of the present invention has a two-layer waterproof system: First, PE polyethylene rods are used to seal the top of the splicing joint, and structural adhesive is applied to the top to form the first layer of material waterproof system; Second, a strip groove is reserved on the side of the precast concrete roof slab, and a PVC drip strip is embedded in the top of the strip groove. After the modular house is spliced, a PC polycarbonate roll of appropriate size is inserted into the strip groove. The PC polycarbonate roll is pre-adheded into a cylinder with tape. After being placed in the strip groove, the tape is cut open at the top of the splicing joint with a tool, so that the PC polycarbonate roll spreads out and is squeezed onto the side wall of the groove to form the second layer of structural waterproof system. The present invention employs two waterproofing measures. The first, material waterproofing, is completed on-site, making construction simple and convenient, largely unaffected by the substrate environment. Upon completion, it prevents most roof water from entering the interior through the joints of the modular houses. The second, structural waterproofing, is primarily manufactured in a factory, directly assembled on-site, and then filled using a pre-finished PC roll material layer. This construction is convenient and unaffected by minor structural deformations. The present invention features simple and fast construction, unaffected by the substrate, excellent waterproofing effect, low cost, and the ability to be reused for construction, thus solving current defects in waterproofing at the joints of modular houses.
