Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a connection structure for assembled buildings. Background Art

[0002] With the advancement of construction industrialization and the rise in labor costs, modular buildings in prefabricated buildings are becoming more and more widely used due to their efficient construction and high degree of assembly.

[0003] Modular buildings can be divided into concrete modules, steel structure modules and wooden structure modules according to their materials. Among them, steel structure module buildings are widely used in temporary epidemic treatment isolation points, cultural tourism, rental housing and other scenarios. The steel structure modules basically complete the layout of interior and equipment in the factory, and then are directly transported to the site for assembly, thereby achieving the goals of high efficiency, environmental protection and manpower saving. When building the frame of existing prefabricated buildings, the connections between the installation rods are generally fastened with bolts. Since some buildings are temporary, this requires multiple disassembly and installation for repeated use. The bolt fixing method makes disassembly and installation more cumbersome and complicated, and inconvenient to operate. For this reason, we propose a connection structure for prefabricated buildings.

[0014] Beneficial Effects

[0015] The utility model provides a connection structure for prefabricated buildings, having the following beneficial effects:

[0016] (1). For the connection structure for prefabricated buildings, by setting a clamping component, the first mounting rod and the second mounting rod are clamped and fixed through a structure similar to the mortise - and - tenon structure. Subsequently, the connection position is initially positioned and finely adjusted by the positioning rod. The movable plate is installed at the position of the fixing groove to play a role in limiting and fixing the connection of the first mounting rod and the second mounting rod, thus ensuring the stability and firmness of the connection between the first mounting rod and the second mounting rod, and enabling the rapid construction of the framework. Secondly, after the framework is installed, the partition plate is installed inside the first mounting groove and the second mounting groove, and the limiting rod plays a role in limiting it and finally strengthens the stable support among the first mounting rod, the second mounting rod, and the support rod.

[0017] (2) The connecting structure for the prefabricated building is provided with an auxiliary component. The limiting block is clamped inside the limiting groove, so that the movable plate is restricted by the sliding plate in the movable groove, thus avoiding interference during the preliminary positioning of the positioning rod. After the first installation rod and the second installation rod are clamped in place, they are fixed. By pulling the connecting plate, the movable plate slides out of the movable groove to the position inside the fixing groove, completing the installation between the first installation rod, the second installation rod and the support rod. Conversely, first slide the movable plate into the movable groove and fix it, which is convenient for the quick disassembly of the support rod. Subsequently, the first installation rod and the second installation rod can also be directly pulled out to complete the disassembly, and the structure is not easily damaged during disassembly.
