Elastic structure formed by insertion-type connection and used for external corner bead as well as protective structure for external corner of parapet wall

Abstract

The invention discloses an elastic structure formed by insertion-type connection and used for an external corner bead. The elastic structure comprises an external-corner-bead fastener and an external-corner fastener which can be connected together in a face-to-face manner by insertion, wherein the external-corner fastener is provided with two wall fixing plates which are fixed to the two side walls of the external corner of a wall respectively; a connecting part of the two wall fixing plates extends out in the direction opposite to the direction of the diagonal line of the included angle between the two wall fixing plates to form a clamping plate; a clamping structure is arranged at one end of the clamping plate; correspondingly, the inner side of the external-corner-bead fastener extendsout in the direction of the diagonal line of the included angle between the two wall fixing plates to form a clamped structure; and the clamped structure on the external-corner-bead fastener and the clamping structure on the external-corner fastener can be connected together in a clamped manner and separated from each other in the direction of the diagonal line of the included angle between the two wall fixing plates. On the basis of the elastic structure, the invention also discloses a protective structure for the external corner of a parapet wall. The elastic structure has the beneficial effects of being capable of well adapting to the uneven state of the external corner of the face of the wall and ensuring that two wings of the external corner bead cover a parapet wall board neatly without leaving gaps.

Description

technical field [0001] The invention belongs to the field of architectural decoration, in particular to an elastic plug-in structure for external corner strips, and on the basis of this, develops and forms a protective structure for external corners of parapet walls using the elastic plug-in structure. Background technique [0002] In interior decoration, external corner strips can be used to protect the external corners of the wall. The cross-section of the traditional external corner strip is L-shaped, and the two right-angled sides are directly fixed to the two right-angled sides of the external corner of the wall by expansion bolts, bonding, etc. After using wall surface covering materials such as wall panels, the method of directly fixing the external corner strips on the external corners of the wall will cause the external corner strips and the wall surface covering materials to be unable to be in the same plane, so it cannot continue to be used.

AI Technical Summary

Problems solved by technology

In reality, the two sides of the external corner of the wall cannot be as straight as a geometric drawing, even if it can be corrected by covering the surface of the wall with covering materials, after the installation of the external corner guard plate of this scheme, the two wings of the external corner guard plate and the The planes where the wall surface covering materials are located still cannot be highly consistent, and there are often gaps, and the gaps cannot be eliminated through installation adjustments, resulting in regrettable decorative effects
