Technical Field

[0001] The utility model relates to the technical field of wall panel installation structures, in particular to an installation structure of a putty-free assembled wall panel. Background Art

[0002] Wall panels are decorative materials used to decorate wall surfaces. Users can customize wall panels with different colors and patterns to suit different architectural styles or the building's interior and exterior environments. Existing wall panel installation methods typically involve applying putty to a flat wall surface and then securing the panel to the surface using the putty's adhesive properties.

[0003] When applying putty, not only must it be applied evenly, but it must also be placed parallel to the wall surface during installation, and then evenly hammered until the wall surface is flush with the adjacent wall. While this wall panel installation structure uses simple materials, it is difficult to install and requires high technical skills from the construction personnel. Utility Model Content

[0032] The two sides of the wall panel 3 are positioned by the wall panel connectors 6 on both sides, and the wall panel connectors 6 can connect two adjacent wall panels 3 into one.

[0033] In this structure, the wall panels 3 are fixed to the structural wall 2 by means of the keel 1, the expansion bolts 4, the self-tapping screws 5 and the wall panel connectors 6, which reduces the installation difficulty and the technical requirements for the construction workers.

[0034] As a preferred embodiment of the present invention, a groove 301 is provided on the outer surface of one end of the wall panel 3 connected to the wall panel connector 6; one end of the groove 301 extends to the side surface of the wall panel 3;

[0035] The head of the self-tapping screw 5 is arranged in the groove 301 ; the groove 301 is provided with a sealant 7 ; the sealant 7 in the groove 301 and the sealant 7 in the gap between two adjacent wall panels 3 are formed in one piece.

[0036] A groove 301 is provided on the wall panel 3 at the position for connecting the self-tapping screw 5; the caulking agent 7 in the groove 301 covers the head of the self-tapping screw 5, and the caulking agent 7 in the groove 301 and the caulking agent 7 in the gap between adjacent wall panels 3 are integrally formed into a whole, which can enhance the strength of the caulking agent 7, and the caulking agent 7 covering the head of the self-tapping screw 5 is not easy to fall off.

[0037] As a preferred embodiment of the present invention, the wall panel connector 6 connecting two adjacent wall panels 3 on the same plane is a planar connector; two mutually parallel first positioning strips 6a are provided on the planar connector; the side surfaces of the two wall panels 3 are respectively tightly pressed against the outer surfaces of the two first positioning strips 6a; and the inner surface of the first positioning strip 6a is provided with a first hook 6a1.

[0038] The first positioning strip 6a is used for unilateral positioning of the wall panel 3, so that the wall panels 3 on both sides of the wall panel connector 6 are aligned; and the first hooks 6a1 on both sides make the space between the two first positioning strips 6a form a structure that is narrow outside and wide inside, reducing the risk of the sealant 7 loosening.

[0039] As a preferred embodiment of the present invention, the two wall panels 3 respectively installed on both sides of the outer top corners of the structural wall 2 are external corner wall panels; the wall panel connector 6 used to connect the two external corner wall panels is a external corner connector.

[0040] The external corner connector is in a right-angle shape; two third positioning strips 6c arranged perpendicular to each other are provided at the top corners of the external corner connector; a reinforcement strip 6d is provided between the two third positioning strips 6c; the wall panel 3 is tightly against the side surface of the third positioning strip 6c away from the reinforcement strip 6d; the side surface of the third positioning strip 6c close to the reinforcement strip 6d is provided with a third hook 6c1; the surface of the reinforcement strip 6d is in a continuous concave-convex shape.

[0041] The third positioning strip 6c is used to limit the unilateral position of the wall panel 3 so that the two external corner wall panels can be perpendicular to each other; a reinforcement strip 6d is provided between the two third positioning strips 6c, which can enhance the impact resistance of the caulking agent 7 between the two third positioning strips 6c; the gap between the two third positioning strips 6c is used for applying the caulking agent 7 to fill the transition position between the two wall panels 3.

[0042] The continuous concavo-convex shape of the surface of the reinforcing strip 6d and the provision of the third hook portion 6c1 can make the connection between the caulking agent 7 and the external corner connector more stable.
