[0002] ALC is the abbreviation of autoclaved lightweight concrete, which is a kind of high-performance autoclaved aerated concrete. ALC board is a multi-porous concrete formed board (containing treated steel reinforcement) made of fly ash (or silica sand), cement, lime and other main raw materials, and cured by high-pressure steam. ALC board can be used as wall material and roof board, and is a new type of building material with superior performance. When installing ALC board, the method of transverse splicing is usually used, and pipe clamps and nail guns are used to fix the ALC board on the cross beam and the ground. However, the above installation and positioning process is prone to deviation, and the ALC board is prone to move under external force, making the installation of ALC board installation node very inconvenient and low in efficiency.

[0003] At present, the patent application file with the application publication number CN113323195A discloses a connecting piece, an ALC installation node structure and a construction method. The connecting piece is used for connecting ALC boards, and includes a fixed part, a first clamping part and a second clamping part.

The second clamping part is connected with the first clamping part, and includes a second U-shaped groove, and the groove opening of the second U-shaped groove faces a second direction. The first U-shaped groove and the second U-shaped groove are suitable for embedding the ALC board. Therefore, according to the connecting piece of the embodiment of the present application, two ALC boards can be nested and connected through the first U-shaped groove facing the first direction and the second U-shaped groove facing the second direction.
