Description

Prefabricated wallboard lateral connecting structure and installation method Technical Field The invention relates to the technical field of assembled building structures, in particular to a prefabricated wallboard lateral connecting structure and an installation method. Background In the assembled concrete structure engineering, the horizontal connection of adjacent precast shear walls is a key for ensuring the structural integrity and the earthquake resistance. At present, common connection modes comprise traditional cast-in-situ integral connection, concave-convex tongue-and-groove post-pouring concrete connection, bolt connection, flexible steel wire rope loop lap joint connection and the like. However, the above-described technique has the following general problems: the traditional cast-in-situ integral connection needs to reserve a gap with a certain width between two prefabricated wallboards, binding reinforcing steel bars, supporting a mould and carrying out a large amount of wet operation on site, and the reserved horizontal rib-out on the side edge of the wall body is easy to collide and deform in the transportation and hoisting processes, needs to be corrected on site and has low installation efficiency. When the concave-convex tongue-and-groove and post-pouring concrete are connected, tenons and grooves are needed to be made on the side edges of each prefabricated wall, two-gun assembled mortises are meshed, a small cavity is reserved in the mortises, fine stone concrete is finally poured in the mortises to be sealed, but the method has extremely high requirements on the production and hoisting positioning precision of the components, installation errors are not easy to adjust, and post-pouring equal wetting operation is still needed. The bolt connection is mostly embedded with metal connection boxes at the edges of the walls, after the adjacent walls are hoisted, the connection boxes at one side are connected with the embedded sleeves at the other side through high-strength bolts in the horizontal direction, and rigid or semi-rigid connection is formed between the walls. The flexible steel wire rope loop lap joint connection is mostly to pre-embed high-strength steel wire rope loops at the edges of the walls, the butt joint steel wire rope loops of two walls are mutually overlapped to form a lap joint area after hoisting, steel bars penetrate from the top end along the center of the rope loops, and finally fine stone concrete or grouting materials are poured in the middle to form an integral shear force transmission area. But the structure has low lateral rigidity, forms limitation on the whole anti-seismic performance, and has strict requirements on the lifting sequence of the wall body and inconvenient construction organization in order to ensure that the steel wire rope rings can be overlapped up and down and have different embedded elevations. Therefore, development of a novel lateral connecting structure and a novel mounting process which are convenient to mount, high in fault tolerance, capable of achieving an anti-collision function, capable of being locked rapidly and high in structural rigidity are needed. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a prefabricated wallboard lateral connecting structure and an installation method, which are convenient to install, high in fault tolerance, high in structural rigidity, capable of being locked quickly and provided with an anti-collision function. The technical scheme adopted for solving the technical problems is as follows: A prefabricated wallboard lateral connection structure is characterized by comprising prefabricated wallboards and vertical dowel bars, wherein L-shaped connection plates are respectively arranged on two sides of the prefabricated wallboards, the L-shaped connection plates on the two sides of the prefabricated wallboards are arranged in a front-back staggered mode in the horizontal direction, semicircular holes are respectively formed in each L-shaped connection plate, and holes formed in horizontal projection surfaces of the semicircular holes in two adjacent L-shaped connection plates on two adjacent prefabricated wallboards are used as dowel bar channels for the vertical dowel bars to penetrate. Compared with the prior art, the invention has the beneficial effects that: The L-shaped connecting plates between the adjacent prefabricated wallboards are arranged in a front-back staggered mode on the horizontal projection surface, are naturally avoided during hoisting, avoid collision, allow arbitrary sequential installation, greatly facilitate construction organization, mechanically lock the two adjacent prefabricated wallboards in a bolt mode, have higher tensile, shearing and pulling rigidity, do not need precise alignment and complex bolt fastening operation, and can be directly inserted into a vertical dowel bar for locking after the wall body is in place, so that th
