Fire resisting window with stepless speed-regulating window closer

Abstract

The invention discloses a fire resisting window with a stepless speed-regulating window closer. The fire resisting window comprises a window frame and a window sash matched with the window frame, andthe window sash is installed on the window frame through spring hinges. The window closer is further installed between the window sash and the window frame. In a non-fire state, a temperature controldevice stops a sliding block from sliding in sliding rails, and a second connection rod slides in an oblong hole so that the fire resisting window can be closed; and when a fire disaster occurs, the temperature control device loses the limiting function for the sliding block, the resilience force of a second spring in the spring hinges is transferred to the second connection rod through the windowsash, the second connection rod and a first connection rod drive the sliding block to slide in the sliding rails, and thus the window closing action is completed. According to the fire resisting window, the window closer is matched with the spring hinges, and the function of automatically closing the window in case of a fire can be achieved.

Description

technical field [0001] The invention relates to the field of fireproof windows, in particular to a fireproof window with a stepless speed regulation shutter. Background technique [0002] 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. [0003] The closing of the existing traditional window closer requires the cooperation of hydraulic cylinders, the mechanical structure is relatively complicated, and the cost is high. On the other hand, the openable angle of the automatic window closers in the prior art is fixed at an angle, cannot be adjusted, has a single for...

[0003] The closing of the existing traditional window closer requires the cooperation of the hydraulic cylinder, the mechanical structure is relatively complicated, and the cost is high

On the other hand, the opening angle of the automatic window closers in the prior art is a fixed angle, which is not adjustable and has a single form, which cannot meet the demand for unlimited opening angles.
