The wall panel 1 includes, but is not limited to, a reinforced concrete slab, for example, a composite material slab for construction work, etc.

In one embodiment, as shown in fig. 2 and 3, the bolt assembly includes an assembling bolt 212 and a plurality of limiting sleeves 211, each limiting sleeve 211 is sequentially sleeved on the assembling bolt 212 along the axial direction of the assembling bolt 212, a part of the limiting sleeves 211 is embedded in the joint end of one wall panel 1, and the rest of the limiting sleeves 211 are embedded in the joint end of the other wall panel 1.

Preferably, the retaining sleeve 211 is pre-embedded in the wall panel 1 when the wall panel 1 is prefabricated. Since each stop collar 211 needs to be sleeved on the assembling bolt 212, that is, each stop collar 211 is coaxial when two wall panels 1 are spliced, the joint end of each wall panel 1 is further provided with a recess 11 for allowing the stop collar 211 on the other wall panel 1 to be embedded, the recess 11 is preferably an arc-shaped recess, and the axis of the arc-shaped recess is coincident with the axis of the stop collar 211 on the corresponding wall panel 1. In one embodiment, as shown in fig. 3, the joint ends of two wall panels 1 are provided with a plurality of semicircular grooves, and the number of the semicircular grooves of each joint end is the same as that of the bolt assemblies and the semicircular grooves are arranged in a one-to-one correspondence manner; each half of the sleeve body of the limiting sleeve 211 is pre-embedded in the corresponding half-round groove and the other half of the sleeve body is embedded in the adjacent other half-round groove.

The semicircular groove preferably penetrates through the two side plate surfaces of the corresponding wall plate 1, and the limiting sleeve 211 on the wall plate 1 is also fixed in the semicircular groove.
