Description

Technical Field

[0001] This utility model relates to the field of hollow sandwich panel technology, and in particular to a hollow sandwich panel that is easy to assemble. Background Technology

[0002] Hollow sandwich panels are a type of structure consisting of two thin slabs on the top and bottom and a hollow section in the middle. This type of structure is widely used in construction engineering, mainly due to its lightweight and high strength characteristics. The design of hollow sandwich panels allows for the reduction of material usage while ensuring sufficient strength, thereby achieving a dual improvement in economic and environmental benefits.

[0003] In use, hollow sandwich panels are connected by steel wires or bolts, which is a cumbersome and time-consuming process. When the hollow sandwich panels are subjected to pressure, the shear keys are easily stressed, which can easily cause the shear keys to break, thus affecting the service life of the hollow sandwich panels. Therefore, we propose a hollow sandwich panel that is easy to assemble. Utility Model Content

[0004] The main objective of this invention is to provide a hollow sandwich panel that is easy to assemble, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hollow sandwich panel that is easy to assemble includes an upper top plate. An upper rib is fixedly installed on the lower surface of the upper top plate. Shear keys are fixedly installed at the four corners of the lower surface of the upper rib. There are four sets of shear keys. The lower surface of the shear keys is fixedly connected to the lower ribs.

[0007] Furthermore, the upper rib includes a connecting plate, a first limiting hole, a first rib plate, a limiting rod, and a limiting groove. The connecting plate is fixedly installed at each of the four corners of the upper surface of the first rib plate. The surface of the first rib plate has multiple limiting grooves. The surface of the first rib plate has eight first limiting holes. The first limiting holes communicate with the limiting grooves. The limiting rod is embedded in the inside of the first limiting hole. There are eight limiting rods in total.

[0008] Furthermore, the shear key includes a lower shell, an upper shell, fixing bolts, a mounting plate, a limiting plate, an embedding groove, and a cross plate. Mounting plates are fitted onto the surfaces of both the lower shell and the upper shell. The mounting plates are fixedly connected by four sets of fixing bolts. Four sets of limiting plates are embedded in the inner surface of the lower shell. Four sets of embedding grooves are formed on the surface of the cross plate. The cross plate is embedded inside the lower shell, and the limiting plate is embedded inside the embedding groove.

[0009] Furthermore, the upper shell is fixedly installed on the lower surface of the first rib at the four corners, and the connecting plates are fixedly installed on the lower surface of the upper top plate at the four corners.

[0010] Furthermore, the lower rib includes a limiting block, a second rib plate, and a second limiting hole. The limiting block is fixedly installed on the surface of the second rib plate. There are multiple sets of limiting blocks, and the surface of each limiting block is provided with a second limiting hole.

[0011] Furthermore, the lower housing is fixedly installed on the upper surface of the second rib at the four corners.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. By using the set limiting rod, first limiting hole, limiting groove, second limiting hole, and limiting block, two sets of hollow sandwich panels can be quickly spliced ​​and assembled, and the assembly is rapid;

[0014] 2. By setting the limiting plate, embedding groove, and cross plate, the strength of the shear key can be effectively improved, thereby further improving the stability of the hollow sandwich panel. Attached Figure Description
