Indoor-outdoor universal expansion joint system for curtain wall

Abstract

The application relates to an indoor-outdoor universal expansion joint system for a curtain wall, and belongs to the technical field of construction of architectural structures. The indoor-outdoor universal expansion joint system comprises an inner cover plate, an inner fastening seat, an inner supporting seat, an outer cover plate, an outer fastening seat, and outer supporting seat, hidden frame trims, a left pillar and a right pillar; the inner cover plate and the outer cover plate are of equal structure. When applied to a curtain wall, the indoor-outdoor universal expansion joint system has the advantages of simple structure, ease of construction, thermal insulation, good energy efficiency, good decorating effect and the like.

Description

technical field [0001] The application relates to a curtain wall indoor and outdoor universal expansion joint system, which belongs to the technical field of building structure construction. Background technique [0002] Expansion joint refers to a structural joint artificially set up to prevent stress damage caused by thermal expansion and contraction of buildings. Buildings with slightly larger engineering volumes are generally equipped with expansion joints. As a modern decorative enclosure structure, glass curtain wall has been widely used in building exterior decoration. Following the setting of expansion joints in the main structure, the glass curtain wall also needs to consider the expansion structure at the expansion joint position. However, the treatment of the expansion joints of the glass curtain wall is often a difficult point. It must not only be able to block wind and rain, but also move with the expansion and settlement of the main structure. Energy saving and...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned defects existing in the existing expansion joints, this application provides a universal indoor and outdoor expansion joint system for curtain walls, which changes the complex structure, high cost, insufficient thermal insulation effect, and ill-considered interior decoration of the previous expansion joints. and other problems, and can be used indoors and outdoors, with simple structure and convenient construction, especially to solve the decoration problem of the interior of the curtain wall, and heat insulation between the inside and outside, to solve the problem of thermal insulation of the curtain wall, so that the glass curtain wall can be placed at the expansion joint position Economical decorative treatment, simple structure, easy construction, heat preservation, energy saving and good decorative effect
