Decorative door-window side line

Abstract

The invention discloses a decorative door-window side line. The decorative door-window side line comprises a pressing cover plate and a bottom plate; the pressing cover plate is provided with an uppergroove which is sunken towards the upper surface of the pressing cover plate and penetrates through the pressing cover plate in the length direction; the upper surface of the pressing cover plate iscorrugated; tenons are arranged on the two outer side faces of the pressing cover plate correspondingly; the bottom plate is provided with a lower groove which is sunken towards the lower surface of the bottom plate and penetrates trough the bottom plate in the length direction; the width of the lower groove corresponds to the width of the pressing cover plate, and the depth of the lower groove corresponds to the height of the pressing cover plate; and mortises matched with the tenons on the pressing cover plate are formed in the two side faces of the lower groove correspondingly so that the pressing cover plate can be mounted in the lower groove in clamped and embedded mode. Compared with the prior art, on one hand, the pressing cover plate and the bottom plate are of a clamping-embeddingstructure, therefore, mounting and demounting are convenient, the time and labor are saved, and construction is easy; and on the other hand, the upper surface of the pressing cover plate is designedto be of a corrugated curved surface structure, so that stress generated after the pressing cover plate is cooled or heated is symmetric and balanced , the shrinking percentage is small, and the defects of warping and the like are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a door and window border for decoration. Background technique [0002] With the improvement of people's living standards, the requirements for beautification of the living environment have been further improved.
