Internal corner connecting structure and mounting method

Abstract

The invention provides an internal corner connecting structure. The internal corner connecting structure comprises an edge closing fixing piece, wherein the edge closing fixing piece is used for closing the edge of the end of a first wallboard and fixing the end of the first wallboard, meanwhile, the edge closing fixing piece is positioned on the wall surface in a screw joint mode, and the edge closing fixing piece further comprises a first mounting buckle groove; the internal corner connecting structure further comprises a buckle connecting piece, the buckle connecting piece is used for being connected with a second wallboard, the buckle connecting piece is provided with a first buckle part inserted into the first mounting buckle groove, the first buckle part is inserted into the first mounting buckle groove to fix the buckle connecting piece to the edge closing fixing piece, and meanwhile, the second wallboard and the first wallboard are vertically spliced; and the first wallboard and the second wallboard at the internal corner are fixed to the edge closing fixing piece and the buckle connecting piece correspondingly, then the edge closing fixing piece and the buckle connecting piece are connected through a clamping groove, finally, the first wallboard and the second wallboard are spliced together in order, fixing is firm, and a proper splicing gap is formed.

Description

technical field [0001] The invention relates to the technical field of indoor wall decoration, in particular to a connection structure and an installation method of an internal corner. Background technique [0002] Yin corner refers to the recessed corner on the wall, also called inner corner, such as the four corners of the house in the room, and the corresponding one is the Yang corner, which refers to the corner protruding from the wall. In the field of prefabricated decoration, the internal corners formed by the connection between wall panels and wall panels will have problems such as splicing irregularly or difficult to splice and fix the internal corners. The role of the corner is only decoration and anti-collision, and has no other functions. At the same time, it protrudes more, and the effect is not ideal in terms of certain aesthetics and vision. [0003] The patent application publication number is CN 207672900 U discloses a clamping type wall internal corner inst...
