Fireproof window with stopping arm device

Abstract

The invention discloses a fireproof window with a stopping arm device. According to the technical scheme, the fireproof window comprises a frame body and two window bodies arranged in the frame body and hinged to the frame body, and fireproof glass is arranged in the window bodies; the frame body comprises an outer frame and a support beam fixedly connected between the opposite inner walls of theouter frame, and the stopping arm device used for stopping the window bodies from being opened and closed are arranged at the position, on one of the opening and closing sides of the window bodies, inthe frame body; the stopping arm device comprises two driving blocks arranged at the positions, facing one side of the opening and closing sides of the window bodies, of the supporting beam, and thetwo driving blocks are located at the two ends of the supporting beam; the two sides of each driving block are each provided with a telescopic arm, one end of each telescopic arm is hinged to the corresponding driving block, and the other end of each telescopic arm is hinged to the inner wall of the adjacent frame end corner; and a driving mechanism for driving the two driving blocks to move to the middle portion of the supporting beam to enable the telescopic arms to extend to be attached to the outer side walls of the window bodies is arranged in the supporting beam. The fireproof window hasthe advantages that the frame body and the window bodies are closed more tightly, and the fireproofing effect of the fireproof window is prolonged.

Description

technical field [0001] The invention relates to the field of building protective windows, in particular to a fireproof window with a retaining arm device. Background technique [0002] A fire-resistant window refers to a window that, together with the frame, can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. Fire windows should be used when lighting and ventilation are required on the outer walls of two buildings with insufficient fire separation distance, or between spaces separated by firewalls. [0003] The existing fireproof window comprises a frame body, and several windows arranged in the frame body and hinged with the frame body, and fireproof glass is arranged in the window body. [0004] If a fire breaks out indoors, personnel will close the window, thereby reducing the gap between the frame and the window, reducing the flow of air, and making it difficult for the fire to spread indoors. However, alt...

Problems solved by technology

However, although it is a fire-resistant window, it still has a certain fire-resistant limit. The long-term high-temperature environment will deform the frame or form of the fire-resistant window, resulting in a gap between the frame and the form, which is easy to introduce heat. to an area that is not on fire, thereby threatening the lives of those trapped in the fire
