[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a precast wall panel for building construction, comprising: a first precast panel 1, a second precast panel 2, and a mesh steel reinforcement frame; the first precast panel 1 and the second precast panel 2 are respectively provided with mesh steel reinforcement grooves on their opposite sides, the mesh steel reinforcement grooves including multiple horizontal grooves 101 and multiple vertical grooves 103, and the mesh steel reinforcement grooves in the first precast panel 1 and the second precast panel 2 are joined to form an installation groove adapted to the mesh steel reinforcement frame, the mesh steel reinforcement frame is engaged between the first precast panel 1 and the second precast panel 2 through the installation groove, the mesh steel reinforcement frame is composed of multiple first reinforcing bars 102 (horizontal bars) and multiple second reinforcing bars 103. The reinforcing ribs 104 (longitudinal reinforcing bars) are welded together in a mesh structure. The first reinforcing rib 102 is correspondingly set in the transverse groove 101, and the second reinforcing rib 104 is correspondingly set in the vertical groove 103. The four corners of the first precast slab 1 and the second precast slab 2 are respectively provided with slots. The slots 3 of the first precast slab and the slots 4 of the second precast slab are joined to form a cavity. The first L-shaped locking block 302 is rotatably connected in the slot 3 of the first precast slab, and the second L-shaped locking block 401 is fixedly set in the slot 4 of the second precast slab. The first L-shaped locking block 302 and the second L-shaped locking block 401 are snapped together and detachably fixed together.

[0024] Specifically, both the first precast slab 1 and the second precast slab 2 are reinforced with steel bars. Figure 2 The figure of the second precast slab 2 is a sectional view, showing the reinforcement in the second precast slab 2.

[0025] Specifically, both the first L-shaped locking block 302 and the second L-shaped locking block 401 include a first side rod and a second side rod perpendicularly connected to the first side rod. The first side rod of the second L-shaped locking block is fixedly installed along the inner wall of the notch in the second precast plate 2. The first side rod of the first L-shaped locking block 302 is rotatably connected to the slot 3 in the first precast plate. The second side rods of the first L-shaped locking block 302 and the second side rods of the second L-shaped locking block 401 are interlocked and connected together by two sets of upper and lower bolts 402. This utility model locks the second side rods of the first L-shaped locking block 302 and the second side rods of the second L-shaped locking block 401 by two sets of upper and lower bolts 402, which can ensure the uniform distribution of locking force, thereby improving the locking effect and the stability of the overall structure.

[0026] In a specific embodiment of this utility model, a locking block 5 is provided on the inner side of the second side rod of the first L-shaped locking block 302, and a locking groove 6 adapted to the locking block 5 is provided on the inner side of the second side rod of the second L-shaped locking block, and the locking block 5 is disposed in the locking groove 6; by engaging the locking block 5 on the inner wall of the first L-shaped locking block 302 with the locking groove 6 on the inner wall of the second locking block, the separation or displacement of the two precast slabs when subjected to external force is effectively prevented, thereby improving the stability and safety of the entire structure.

[0027] In a specific embodiment of this utility model, positioning blocks 7 are fixedly connected to the two sides of the above-mentioned mesh steel reinforcement skeleton at the four corners respectively (that is, four positioning blocks 7 are fixedly connected to the front and back of the mesh steel reinforcement skeleton respectively), and positioning grooves 8 adapted to the positioning blocks 7 are respectively provided on the inner side of the first precast slab 1 and the second precast slab 2. The positioning blocks 7 and the positioning grooves 8 are engaged to facilitate alignment and effectively prevent the wall panels from shifting or misaligning during assembly.

[0028] In a specific embodiment of this utility model, the slot 3 of the first precast slab is rotatably connected to a first L-shaped locking block 302 via a support shaft 301; that is, the first L-shaped locking block 302 rotates within the slot 3 of the first precast slab via the support shaft 301, thereby facilitating the first L-shaped locking block 302 to engage with or separate from the second L-shaped locking block 401, and to be locked by bolts 402, thereby making the connection between the two precast slabs more stable and less prone to loosening or deformation.

[0029] This invention first divides the precast wall panel into two precast panels, and then connects the first precast panel 1 and the second precast panel 2 with a mesh steel reinforcement skeleton. This strengthens the structural stability of the wall panel and improves the connection strength between the precast panels, effectively resisting external forces and preventing displacement or deformation of the wall panel during use. It also enhances the overall rigidity and stability of the wall panel. The mesh steel reinforcement skeleton further enhances the deformation resistance of the wall panel. The mesh structure can effectively disperse and bear forces from all directions, improving the overall rigidity and stability of the wall panel.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
