Description

[Technical field]

[0001] The invention relates to the technical field of wall panel mounting pieces, in particular to the technical field of a wall panel mounting connector. [Background technology]

[0002] In recent years, prefabricated buildings have become a hot topic of research and exploration in China due to their advantages such as high efficiency, high quality and low cost. Building walls are an important part of buildings, so the industrialization of walls is the first choice for achieving building industrialization. In the field of prefabricated buildings, my country has conducted in-depth research and discussion on key technical issues in the design, production and construction of prefabricated exterior wall panels, and has applied and demonstrated them in actual projects.

[0003] At present, prefabricated exterior walls such as gypsum board facing panels are widely used due to their light texture, high strength, fire resistance, moth resistance, and easy processing. They are usually connected to the main structure of the building by self-tapping screws or glue. However, self-tapping screws are prone to cracking around the substrate, are easy to loosen, and the nuts are exposed to the outside, which is not beautiful. Glue has insufficient bonding strength and is not environmentally friendly. These two assembly methods are basically fixed and cannot be disassembled. After assembly, it is inconvenient to disassemble and replace. Therefore, in the construction of indoor building decoration projects, simple, durable, and easy to repair and replace wall hanging systems are widely used.

[0004] The existing wall hanging system generally uses hardware hangers to hang the decorative panels on the wall, which is relatively complicated to install and requires drilling holes in the decorative panels to embed the hangers. Some wall hanging connectors also have complex structures, and the wall panels are easy to loosen after installation. They have high requirements for the flatness of the wall surface and are not suitable for gypsum board wall panels. [Summary of the invention]

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose a wall panel installation connector that can facilitate the disassembly, replacement and adjustment of the wall panel. It does not require drilling, screws and adhesives during installation. It has a simple structure and has low requirements for the flatness of the wall surface.

[0006] To achieve the above-mentioned purpose, the present invention proposes a wall panel installation connector, including a plug-in and a grabbing piece, wherein a plurality of spikes for connecting the wall panel are provided on the back of the grabbing piece, a plug-in connecting portion is provided on the front of the grabbing piece, and an insertion interface is formed between the inner wall of the plug-in connecting portion and the front of the grabbing piece, a bending portion bent away from the front of the plug-in is provided at the bottom of the plug-in, and a locking portion is provided on the front of the plug-in, and a keel hanging area is formed between the bending portion and the front of the grabbing piece after the plug-in and the grabbing piece are connected together.

[0007] Preferably, a plurality of rows of spikes are provided on the back of the gripping piece and the connecting lines of the spikes in each row are serrated, forming a point-formal nail-gripping structure, which increases the nail-gripping force and the bearing capacity, and ensures the firmness of the connection between the gripping piece and the wall panel.

[0008] Preferably, four rows of spikes are provided on the back of the gripping piece, and the four rows of spikes are symmetrically distributed in pairs above and below the plug-in connecting portion, so that the overall force distribution of the gripping piece and the wall panel is relatively uniform after installation and connection.

[0009] Preferably, the gripping piece is provided with at least one hollow groove to reduce the weight of the gripping piece and save materials.

[0010] Preferably, the number of the hollow grooves is 4, which are two transverse hollow grooves and two longitudinal hollow grooves respectively.

[0011] Preferably, the two transverse hollow grooves are respectively located above and below the plug-in connecting portion, and the two longitudinal hollow grooves are respectively located on the left and right sides of the plug-in connecting portion.

[0012] Preferably, a reinforcing rib is provided on the back of the plug-in to increase the bearing capacity of the plug-in.

[0013] Preferably, the thorn spikes are formed by punching with a mold suitable for the thorn spikes and then flipping to a side away from the back of the gripper, and a thorn spike hollow groove suitable for the thorn spikes is formed on the gripper.

[0014] Preferably, the spike is in the shape of a right-angled trapezoid, the right-angled end of the spike is connected to the back of the gripping piece, and the oblique tip of the spike is away from the back of the gripping piece.

[0015] Preferably, the plug-in connection portion is an arch formed on the front side of the gripper after being stamped by a mold adapted to the plug-in connection portion.

[0016] Beneficial effects of the present invention: The present invention forms a keel hanging area between the bending part and the grabbing piece by plugging the plug-in piece and the grabbing piece together, and the back side of the grabbing piece is connected to the wall panel by a plurality of staggered spikes, so that the wall panel is easy to disassemble, replace and adjust, and the wall panel hanging installation does not require drilling, screws and adhesives. The overall structure of the wall panel installation connector is simple, and the requirement for the flatness of the wall surface is low. The wall panel is not easy to loosen after hanging installation.
