A steel door and window and a curtain wall with the door and window

Abstract

The invention discloses a steel door window and a curtain wall provided with the same. The steel door window comprises a steel frame body and a steel fan body hinged with the steel frame body. The steel frame body comprises a main frame and an auxiliary frame capable of being assembled and disassembled in the main frame. A main stopping edge is arranged on the main frame. An auxiliary stopping edge is arranged on the auxiliary frame. When the main frame is not provided with the auxiliary frame, the steel fan body is buckled in the main body and is pressed on the main stopping edge in a closed condition. When the main frame is provided with the auxiliary frame, the auxiliary stopping edge is placed on a side opposite to the main stopping edge. The steel fan body is buckled in the auxiliary frame and is pressed on the auxiliary stopping edge in the closed condition. The steel door window has the advantages of being simple and flexible in structure, low in cost and high in adaptability. According the curtain wall, the steel door window is arranged on a curtain wall body.

Description

technical field [0001] The invention relates to a door and window and a curtain wall, in particular to a steel door and window 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, large heat transfer coefficient, no heat p...

AI Technical Summary

Problems solved by technology

[0005] At present, the technical problem of high-grade steel doors and windows is limited by the sealing requirements. At each door and window installation position, the opening direction of the fan body is fixed and cannot be selected due to the limitation of the installation structure. The combined installation structure of the frame body and the fan body is too fixed. Single, poor flexibility, can not meet customer needs well
