[0002] At present, ALC strips (lightweight concrete panels) are widely used in the field of office buildings. They have the advantages of light weight, low rigidity, less impact on structural stress, and unified modulus. It saves a lot of wet plastering work on site for subsequent decoration projects, and at the same time improves construction accuracy. ALC strips are currently mainly used in office buildings, and are widely used in prefabricated structures. In the prior art, the hook bolts reserved on the ALC strips are often used to connect with the angle steel welded on the reserved metal embedded parts of the structural column. This connection method mainly has the following disadvantages:

[0003] 1. Concrete structural columns generally need to be cast later, and the conditions for reserving metal embedded parts are limited. The construction is cumbersome and the formwork is difficult, which greatly limits the construction efficiency of prefabricated buildings;

[0004] 2. Large amount of steel is used and the cost is high;

[0005] 3. The wall reserved bolts have high precision requirements, which makes construction and installation difficult;

[0006] 4. The construction controllability is poor, which can easily cause problems such as loose pouring and misalignment of metal embedded parts, resulting in low quality of the finished product and even affecting the quality and safety of the project.

[0007] 5. Angle steel and hook bolts are exposed on both sides of the interior and exterior, and require a thick surface layer to cover them, which goes against the original intention of ALC strips to avoid plastering.

[0008] Therefore, the existing conventional connection form between ALC strips and concrete structural columns has many disadvantages, and it is urgent to construct a connection form that can effectively enhance the stability of the ALC strips, reduce the amount of steel used and reduce the project cost.
