[0002] In prefabricated buildings, it is usually necessary to horizontally join precast wall panels (hereinafter referred to as wall panels) on the foundation. The existing connection method is as follows: The wall panels are embedded with protruding steel bars in the horizontal direction (length direction X). When two wall panels are butted, the protruding steel bars are connected and then grouted to seal. The wall panels and the foundation are fixed by connectors and bolts. The connector is L-shaped, with one side lapped on the outer surface of the wall panel and the other side lapped on the foundation, and then the connector is fixed to the wall panel and the foundation by bolts. This connection method has the following problems:

[0003] (1) The protruding steel bars need to be set in the height direction Y of the wall panel, resulting in more steel consumption and a more complex prefabrication process;

[0004] (2) Bolt connection makes the operation steps cumbersome and increases the workload;

[0005] (3) Bolt connection forms connection points at the joint of the wall panels. After connection, a covering box needs to be covered, affecting the indoor roughcast effect. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a horizontal connection structure for precast wall panels, which simplifies the operation and reduces the steel consumption.

[0007] The technical solution of the utility model is: A horizontal connection structure for precast wall panels is used for connecting two horizontally butted wall panels and the foundation. The foundation is placed at the lower end of the wall panel. The horizontal connection structure for precast wall panels includes a first steel bar, a second steel bar, and a third steel bar. A groove is provided in the wall panel, and the groove penetrates one side in the length direction X of the wall panel. The grooves in two butted wall panels are connected. The first steel bar is embedded in the foundation and extends into the groove. The second steel bar is embedded in the wall panel and extends into the groove. The third steel bar encloses the first steel bar and the second steel bar in the two grooves at the same time. A slurry layer for fixing the first steel bar, the second steel bar, and the third steel bar is filled in the groove.

[0008] Preferably, a grouting hole is provided in the wall panel. One end of the grouting hole penetrates the outer surface of the wall panel, and the other end of the grouting hole is communicated with the groove.

[0009] Preferably, the first steel bar is arranged close to the edge of the wall panel, the second steel bar is arranged close to the inside of the wall panel, and there are two second steel bars in the thickness direction Z of the wall panel. The first steel bar and the two second steel bars form a triangle.

[0010] Preferably, each groove in the wall panel is provided with at least one first steel bar and a second steel bar, and the first steel bar and the second steel bar extend along the height direction Y of the wall panel.

[0011] Preferably, at least two of the third steel bars are arranged at intervals in the height direction Y.

[0012] Preferably, a grouting layer is provided between the foundation and the wall panel.

[0013] Preferably, a joint is formed between two butt-jointed wall panels, and a sealing layer is provided in the joint.

[0014] Compared with the related art, the beneficial effects of the present utility model are as follows:

[0015] First, the L-shaped connecting piece is cancelled, and the foundation and the wall panel are directly connected by steel bars, so that there is no connection point at the joint of the wall panel, and there is no need to construct the on-site plugging box anymore, which improves the indoor roughcast effect and reduces the factory production process steps, realizing quality control.

[0016] Second, the protruding steel bars extending in the X direction are no longer provided in the height direction Y of the precast wall panel, and only the first steel bar and the second steel bar need to be connected by the third steel bar, reducing the steel consumption.

[0017] Third, the construction difficulty is reduced, the operation steps are simplified, the construction period is shortened, the structural integrity is enhanced, the bearing force performance of the connecting piece is increased, and full-assembly installation is realized.
