Description

Technical Field

[0001] The utility model relates to the field of prefabricated houses, in particular to a prefabricated house assembly joint structure. Background Art

[0002] A prefabricated house refers to a building that is produced in an industrialized manner and integrates systems such as structures, components, and equipment under the principles of standardization, modularization, and serialization, and can be assembled and constructed on-site. Coupled with the increasing number of traditional buildings, the gradual scarcity of land resources, the growing urban pollution, the intensification of problems such as climate warming and the difficult treatment of construction waste, prefabricated houses are gradually being recognized. Many development zones, real estate developers, tourist attractions, new rural construction projects, individuals, etc. have taken a fancy to this very advantageous product. Rapidly promoting prefabricated houses has become a major highlight in the new materials and construction fields this century.

[0003] A prefabricated modular house disclosed in a Chinese utility model (publication number: CN215802229U) includes a foundation module, a ceiling module, a wall module, and a load-bearing module. One end of the load-bearing module is connected to the foundation module, the other end of the load-bearing module is connected to the ceiling module, the wall module is connected to the load-bearing module, and the wall module is arranged above the foundation module and below the ceiling module; splitting the house structure into a foundation module, a ceiling module, a wall module, and a load-bearing module can avoid in-situ concrete pouring, make on-site wall construction fast and simple, save the construction period, and the wall has high strength. At the same time, it is convenient for transportation and can be better industrialized and popularized; only by using connecting pieces can the foundation module, the ceiling module, the wall module, and the load-bearing module be connected into a whole. The connection nodes are safe and reliable, the structure has good durability, and the on-site assembly process is simple; a number of lifting rings are arranged on the ceiling module for convenient lifting.

[0004] In the prior art, prefabricated houses are assembled by splicing modules such as a foundation module, a ceiling module, a wall module, and a load-bearing module. However, a large number of assembly joint structures are required in the splicing process. There are already various assembly joint structures for prefabricated components on the market, but they all have more or less complex installations. Therefore, a prefabricated house assembly joint structure is now proposed. Summary of the Utility Model

[0023] 1. After the connector passes through the reserved positioning holes of the two connecting plates, the two ends of the utility model are threadedly connected to the fasteners so that the two groups of prefabricated walls are fixed, and the prefabricated walls can be quickly assembled and installed. At the same time, the fasteners and the sleeves are threadedly connected, so that the sealing gaskets are in contact with the outer wall of the connecting plates, thereby sealing the connection position of the connector and the fasteners to avoid corrosion caused by rain or oxidation, which may lead to looseness and danger.

[0024] 2. The utility model rotates the penetration rod to slide along the placement tube, thereby abutting against one side of the sleeve, thereby preventing the sleeve from loosening, further maintaining the stability of the connection between the connecting piece and the fastener, and allowing the staff to turn the penetration rod for rotation through the anti-slip sleeve.

[0025] 3. The utility model uses a metal folding piece fixed on the connecting plate to conveniently shield the connecting gap between the two connecting plates, and cooperates with the metal plate to further shield the gap to prevent moisture from entering and causing corrosion to the connecting piece. The angle steel inside the metal folding piece improves the rigidity and bearing capacity, and the waterproof membrane is bonded to the top of the metal folding piece by structural adhesive to avoid water seepage.
