Decorative joint structure of curtain wall sandwich panel

Abstract

The invention provides a decorative joint structure of a curtain wall sandwich panel. The decorative joint structure comprises a heat preservation structure, two first clamping pieces, second clamping pieces and a vertical metal buckling groove, wherein the heat preservation structure is arranged in a vertical gap; the two first clamping pieces are located on the two sides of the vertical gap; each first clamping piece is provided with a mounting part and a first clamping part, and the first clamping part extends outwards from the end, close to the vertical gap, of the mounting part; the second clamping pieces are mounted on the first clamping part of the first clamping piece on the left side and the first clamping part of the first clamping piece on the right side in a clamped mode and located on the outer side of the heat preservation structure; and the vertical metal buckling groove is provided with a first plate part extending vertically and a first connecting part located on the inner side of the first plate part, and the first connecting part is connected with the second clamping pieces in a clamped mode. Due to the fact that the first clamping pieces, the second clamping pieces and the vertical metal buckling groove are arranged, the vertical metal buckling groove is arranged, so that weather-proof sealant of a vertical decorative joint is protected against damage of wind and sun, and the overall metal texture of the metal curtain wall sandwich panel is better reflected.

Description

technical field [0001] The invention relates to the field of roof and wall surfaces of prefabricated buildings, in particular to a decorative seam structure of a curtain wall sandwich panel. Background technique [0002] With the application of metal face sandwich panels more and more widely. In particular, prefabricated buildings are vigorously promoted in my country, and metal sandwich panels used for roofs and walls are indispensable components of prefabricated buildings. As a kind of metal sandwich panel, the curtain wall sandwich panel has more characteristics of metal curtain wall; although it is also prefabricated in the factory, its flatness and waterproof performance after installation are much better than ordinary metal sandwich panels. [0003] Currently, if figure 1 with figure 2 As shown, the curtain wall sandwich panel 10 is generally also composed of three parts: an outer panel 101 , a thermal insulation core material 103 , and an inner panel 102 . The in...
