Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated buildings, and particularly relates to a connection structure for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building assembled at the construction site by transferring a large amount of on-site operation work in the traditional construction method to the factory, fabricating building components and fittings in the factory, transporting them to the building construction site, and assembling them at the site through reliable connection methods.

[0003] For the prefabricated building structure, in the prior art, after retrieval, the utility model patent with the Chinese patent publication number CN213115031U discloses a connection structure for prefabricated buildings, as Figure 1 shown. It mainly includes a precast slab a. A clamping plate b is arranged on one side of the precast slab a, and a clamping groove c is arranged on the other side. The front and rear sides of the clamping plate b are connected with a telescopic positioning rod e through a spring d. At the position where the clamping groove c is arranged on the precast slab a, a positioning hole is provided. During assembly, the clamping plate b and the clamping groove c of adjacent precast slabs a are buckled together, and are clamped and fixed through the telescopic positioning rod e.

[0004] In the prior art, for the prefabricated building structure similar to the above technical solution, it is found that there are areas to be improved during the actual implementation process: for the above prefabricated building structure, the adjacent precast slabs are buckled together, and the connection is fixed by the positioning rod controlled by the spring. This makes the connection between adjacent precast slabs only limited by the positioning rod controlled by the spring, without rigid connection. Moreover, after connection, the adjacent precast slabs are still independent individuals, resulting in poor stability of the assembly structure. Summary of the Invention

[0005] In view of the deficiencies and defects existing in the prior art, the purpose of the present utility model is to provide a connection structure for prefabricated buildings, which solves the problem that in the prefabricated building structure in the prior art, the precast wall panels are only limited and connected by positioning rods, and after connection, the adjacent precast slabs are still independent individuals, resulting in poor stability of the assembly structure.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions: An assembled building connection structure includes precast wall panels. Adjacent precast wall panels are connected by connecting wall panels. On the left and right sides of the precast wall panels, a plurality of n-shaped protruding steel bars are provided from top to bottom, and the corresponding protruding steel bars on the left and right sides are staggered up and down. A connecting wall panel is provided between the left and right adjacent precast wall panels. The protruding steel bars of the left and right adjacent precast wall panels are stacked in contact up and down, and avoiding holes are provided on the connecting wall panel at positions corresponding to the protruding steel bars. The left and right sides of the avoiding holes penetrate through the connecting wall panel. Two through holes penetrating the connecting wall panel are vertically provided on the connecting wall panel. Each avoiding hole is communicated with the through hole. The precast wall panel and the connecting wall panel are connected by the concrete poured in the through hole and the avoiding hole.

[0007] As a further improvement of the present utility model, small grooves are provided between the upper and lower two protruding steel bars on the left and right sides of the precast wall panel. After the left and right adjacent precast wall panels are connected by the connecting wall panel, the small grooves are communicated with the avoiding holes.

[0008] As a further improvement of the present utility model, two lifting plates are provided on the front and rear sides of the precast wall panel, and lifting hanging rings are provided on the lifting plates.

[0009] As a further improvement of the present utility model, a window opening is provided on the precast wall panel.

[0011] 1. By providing protruding steel bars on both the left and right sides of the precast wall panel, and providing a connecting wall panel between the left and right adjacent precast wall panels, and providing avoiding holes on the connecting wall panel at positions corresponding to the protruding steel bars, and two through holes penetrating the connecting wall panel are vertically provided on the connecting wall panel. During connection, the protruding steel bars on the left and right adjacent precast wall panels are inserted into the avoiding holes on the connecting wall panel, and the contact surfaces of the left and right adjacent precast wall panels and the connecting wall panel are aligned. At this time, the protruding steel bars on the left and right adjacent precast wall panels are in contact with each other up and down. Then, concrete is poured from the upper end of the through hole downward. At this time, the concrete flows from the through hole into each avoiding hole, and flows into the contact gap between the precast wall panel and the connecting wall panel from the left and right ends of the avoiding hole. After the concrete solidifies, it will firmly rigidly connect the contact surfaces of the precast wall panel and the connecting wall panel together, and the concrete in the avoiding hole firmly connects the protruding steel bars on the left and right sides of the precast wall panel together. Then, after the final connection, the precast wall panel and the connecting wall panel can firmly form a whole, and the connection stability is relatively strong.

[0012] 2. By providing small grooves between the upper and lower protruding steel bars on both the left and right sides of the precast wall panel, after the adjacent left and right precast wall panels are connected by the connecting wall panel, the small grooves communicate with the avoidance holes, and the concrete will flow into the small grooves from the avoidance holes, thereby improving the connection firmness between the precast wall panel and the connecting wall panel.

[0013] 3. By providing two lifting plates on both the front and back sides of the precast wall panel, and lifting hanging rings are provided on the lifting plates, it is convenient to lift the precast wall panel. BRIEF DESCRIPTION OF THE DRAWINGS
