Plastic external corner angle bead for inner wall of building and construction method for internal and external corners of inner wall of building

Abstract

The invention discloses a plastic external corner angle bead for an inner wall of a building and a construction method for internal and external corners of the inner wall of the building. The plastic external corner angle bead comprises a surface type veneer external corner angle bead or coating type veneer external corner angle bead for protecting the external corner of the inner wall in construction, wherein the surface type veneer external corner angle bead and the coating type veneer external corner angle bead are both arranged from front to back along the length direction of the protected external corner; the cross section of the coating type veneer external corner protector is Y-shaped and the external corner angle bead comprises a corner protector lath arranged on the protected external corner as well as a first pressure strip and a second pressure strip which are respectively connected with the inner end of the corner angle bead lath; the surface type veneer external corner angle bead comprises a corner angle bead strip and a third pressure strip arranged on the corner angle bead strip; the cross section of the corner angle bead strip is of a sector shape. The construction method for the internal and external corners comprises the following steps of: (I) base layer cleanup; (II) construction on the internal and external corners. The internal and external corner angle bead disclosed by the invention is simple in structure and reasonable in design; the construction method for the internal and external corners has simple steps and reasonable design, is convenient to realize and easy in control over the construction quality, and can be used for solving multiple problems of an existing construction method for the internal and external corners of the inner wall of the building.

Description

technical field [0001] The invention belongs to the technical field of construction of internal and external corners of building inner walls, and in particular relates to a plastic external corner protector for internal walls of buildings and a construction method for internal and external corners of internal walls of buildings. Background technique [0002] Walls are divided into exterior walls and interior walls according to their position and direction in the building. The walls arranged along the perimeter of the building are called exterior walls, and the walls surrounded by exterior walls are called interior walls. The outer wall is an outdoor air partition wall, and it is a wall that is in direct contact with the outdoor air, mostly a "cold wall". The inner wall plays the role of separating the space indoors, and it is a wall that is not in direct contact with the outdoor air, and is mostly a "warm wall". According to different materials and construction methods, com...

Problems solved by technology

Nowadays, in the construction process of paint-based wall finishes and veneer-based wall finishes, especially when constructing wall finishes at the yin and yang corners of interior walls, there is no unified, standardized and specific construction method to follow. Therefore, in the actual construction, there are inevitably many problems such as relatively random construction operations, irregularities, low construction workers, and poor construction quality of the internal and external corners. Defects and deficiencies such as unsightly appearance, easily damaged male corners, and difficult repair of damaged male corners
