A steel door and window made of heat-insulating broken bridge and a curtain wall with the door and window

Abstract

The invention discloses a heat insulation bridge-cutoff steel door window and a curtain wall provided with the same. The door window comprises a steel frame body with a heat insulation bridge-cutoff structure and a steel fan body with the heat insulation bridge-cutoff structure. The steel frame body is hinged with the steel fan body. A first sealing strip is arranged on an opening side of the fan body between the steel frame body and the steel fan body. A second sealing strip is arranged on a closing side of the fan body between the steel frame body and the steel fan body. The heat insulation bridge-cutoff steel door window is simple and firm in structure, low in cost, heat-insulating and environment-friendly. According to the curtain wall, the heat insulation bridge-cutoff steel door window is arranged on a curtain wall body.

Description

technical field [0001] The invention relates to a steel door and window and a curtain wall, in particular to a steel door and window with a heat-insulating broken bridge and a curtain wall with the door and window. Background technique [0002] Steel door and window technology develops rapidly in economically developed countries and is widely used, but it is neglected in our country. The key problem is that the old inferior steel doors and windows have deep-rooted adverse effects on people. Before the 1980s, steel doors and windows occupied a dominant position in my country's metal doors and windows. After the 1980s, with the gradual deepening of reform and opening up, my country's national economy has developed rapidly, and the level of science and technology has continued to improve. People began to think that steel Doors and windows are not suitable for use in high-rise buildings due to their simple cross-sectional structure, low strength, no sealing measures, air leakage,...

AI Technical Summary

Problems solved by technology

It is relatively easy to obtain a precise cross-sectional shape of aluminum profiles through hot melting and extrusion processes, and the elastic deformation of aluminum materials is small, and it is easy to realize the aluminum alloy broken bridge occlusal process, so it is easier to form a composite structure of thermal insulation and broken bridges; while the thermal insulation of steel The cost of melting and extrusion is too high, it is not suitable to use the same forming process as aluminum profiles, and it is impossible to form a precise seal installation structure, and the elastic deformation of steel is large, it is difficult to achieve the occlusal process like aluminum alloy broken bridges. Therefore, steel It is difficult to form a thermal insulation bridge for doors and windows, which cannot meet the high-end environmental protection requirements of thermal insulation
