Dry type curtain wall structure based on equal-pressure cavity design

Abstract

The invention provides a dry type curtain wall structure based on equal-pressure cavity design. The dry type curtain wall structure is characterized in that an equal-pressure cavity and a drainage channel are formed through combination of curtain wall structures, wherein a groove is formed in a curtain wall stand column cross beam and connected with heat insulation strips; glass is installed on the two sides of the heat insulation strips; the heat insulation strips comprise the vertical heat insulation strips and the transverse heat insulation strips; the vertical heat insulation strips are connected with vertical outdoor side waterproof rubber strips; the vertical outdoor side waterproof rubber strips are connected to the surface of the glass through double-sided adhesive tape and are fixed and pressed by aluminum alloy pressing plates through screws; transverse full-length sealing drainage rubber strips transversely cross a stand column and are arranged in a full-length mode; the transverse full-length sealing drainage rubber strips cover the surface of the curtain wall stand column and the surface of the glass on the lower side to form a water spreading layer; the transverse full-length sealing drainage rubber strips and vertical indoor side sealing rubber strip profiles of a vertical curtain wall are in lap joint and spliced to be tightly combined to form an airtight layer;the water spreading layer and the airtight layer jointly form a transverse full-length waterproof face; and the aluminum alloy pressing plates are provided with vent holes and drainage holes.

Description

technical field [0001] The invention relates to the technical field of curtain wall structures, in particular to a dry curtain wall structure based on an isobaric chamber design. Background technique [0002] Curtain walls are widely used as exterior walls of buildings, especially exterior glass walls, metal walls, plate walls, etc. of modern buildings. A curtain wall includes glass panels that form a major part of the exterior surface of a building, and curtain wall support structural members. Structural elements typically include columns (ie, vertical members) and beams (ie, horizontal members) between which glass panels are hermetically mounted and supported to form the exterior walls of the building. The structure also includes aluminum alloy press plates attached to the columns and beams to form the sashes in which the glass panels are held. In the original technology, silica gel is usually used to seal between the aluminum alloy platen and the glass panel, which cann...

AI Technical Summary

Problems solved by technology

In the original technology, silica gel is usually used to seal between the aluminum alloy platen and the glass panel, which cannot form an isobaric cavity structure and cannot form effective drainage measures. However, the use of silica gel is prone to secondary pollution, and the curtain wall silica gel seal that completely relies on silica gel sealing The layer is always under the pressure difference between indoor and outdoor, and the curtain wall has to bear the deformation caused by the wind load. The thin glue joint is very easy to break under the influence of these various factors, causing leakage in rainy days, which has a great impact on the airtightness and watertightness of the curtain wall. Performance, energy saving, etc. and interior decoration cause damage that is difficult to assess
