It will be appreciated that in use the connector 2 is inserted into a hole 11 in a wall panel. The connecting members are usually connected to the main structure, which is usually a concrete floor or a beam, using anchor bolts, and therefore corresponding anchor bolt holes 5 are required in the connecting plates 1.
As a specific embodiment of the connecting piece, the connecting part 2 is positioned in the middle of the surface of the connecting plate 1. It should be understood that the connecting plate 1 is provided with anchor holes 5 at both ends, and the connecting part 2 is located between the two anchor holes 5 to ensure the connecting strength of the wall panel and the main structure, which is suitable for the installation of the wall panel in the high-intensity area.
Optionally, the connecting portion 2 is formed by two rectangular steel plates 3 fixed on the surface of the connecting plate 1, and the two rectangular steel plates 3 are arranged in parallel, so that the manufacturing of the connecting piece is simplified, and the production and manufacturing efficiency of the connecting piece is improved.
Optionally, the connecting portion 2 is a hollow cylindrical steel plate fixed on the surface of the connecting plate 1, so that the wallboard is ensured to be firmly installed and fixed.
The connecting method for connecting the hollow prefabricated wall panel and the main body structure by adopting the connecting piece in the embodiment comprises the following steps:
Filling holes 11 which need to be inserted into the connecting parts 2 with C15 fine stone concrete, wherein the filling length is more than or equal to 100 mm; specifically, holes 11 at about one third of the left and right positions of the upper and lower ends of the wallboard are filled and compacted. Wherein to filling real control of length, can set up the support component that both ends have the baffle in hole 11, the cross sectional area and the hole cross sectional area adaptation of baffle, two baffles pass through the bracing piece and connect, and the length of hole minus the length of bracing piece is the total that fills real length at both ends promptly. Or a foam plate is inserted into the hole 11 to control the concrete filling length and prevent the concrete mortar from flowing into the middle of the hole.
Then inserting the connecting part 2 into the filled hole 11 to primarily connect the connecting part with the wallboard and prevent the connecting part from falling off the wallboard; it should be ensured that the anchor openings 5 of the connecting plates 1 are located on the outside of the wall panels to facilitate the fixing of the connecting plates 1.
And then the lower connecting piece of the wallboard is tightly pushed, so that the lower end of the wallboard abuts against the connecting plate 1 of the lower connecting piece of the wallboard, and a gap of 5-10 mm is reserved between the connecting plate of the upper connecting piece of the wallboard and the upper end of the wallboard.
Cleaning the ground of the main structure, scribing and positioning according to the position of the partition wall, smearing micro-expansion concrete with the thickness of 20-30 mm at the mounting position of the lower end of the wallboard, smearing micro-expansion concrete with the thickness of 8-12 mm at the top surface of the wallboard, horizontally pushing the wallboard into the mounting position, and enabling the connecting piece at the upper end of the wallboard to be tightly propped against the main structure at the upper part.
After the wallboard is positioned, the connecting plate 1 of each connecting piece is fixed with the main structure, if the connecting plate is fixed through the anchor bolt 4, the wallboard is connected with the main structure.
Meanwhile, the wall boards are connected by adopting a mortise and tenon structure and/or bonded by mortar, so that the connection strength of the wall body and the main structure is further improved.
And circulating in this way, completing the installation of the wall body so as to treat further decoration and beautification treatment.
