Description

A steel-aluminum combination fireproof window with a spring-pushed heat-sensitive latch

technical field

The utility model relates to the field of fireproof doors and windows, in particular to a steel-aluminum combination fireproof window with a spring-propelled heat-sensitive latch.

Background technique

The national standard GB50016-2014 "Code for Fire Protection Design of Buildings" stipulates that for residential buildings with a building height greater than 54 meters, each household should have a room with an openable external window, and the fire-resistant integrity of the external window should not be less than 1 hour. The national standard GB16809-2008 "Fireproof Windows" also stipulates that fireproof windows must be equipped with automatic window closers.

At present, the mainstream aluminum alloy door and window profiles are made into door and window products. In addition to the good fire resistance and energy saving performance of the glass, the profiles must also have good fire protection and heat insulation functions. However, if the aluminum alloy door and window profile structure commonly used now encounters a fire, as the heating time increases and the temperature rises, the high temperature resistance is limited, and the final profile is damaged, unable to support the glass, and the glass collapse will cause serious damage. Casualties and property losses, and the collapse of glass can make the fire spread rapidly, with serious consequences.

In order to solve the above problems, an automatic window closer is used on the fireproof window. When a fire occurs, the automatic window closer will automatically close the window, and the fire prevention function is better. In the case of high temperature and continuous fire, although the separate automatic window closer can ensure the airtightness of the window sash, there may be cracks on the edge of the window far away from the window closer, which is not good for the airtightness of the fire prevention. The sealing and fireproof function of the fireproof window needs to be improved.
