A broken bridge type fireproof window

Abstract

The invention discloses a broken-bridge-type fireproof window. The broken-bridge-type fireproof window comprises a bottom rod, window beams are installed at the two sides at the upper portion of the bottom rod, two side rubber strips are installed on the inner walls of the window beams and made of fireproof and ageing-resistant materials, two broken-bridge aluminum window frames are installed at the inner sides of the window beams, a square broken-bridge aluminum frame is installed above the broken-bridge aluminum window frames, and fireproof glass is installed at the inner sides of the squarebroken-bridge aluminum frame and the broken-bridge aluminum window frames; a motor switch is installed on the front end faces of the window beams, the broken-bridge aluminum window frames comprise first window frame aluminum section bars, two window frame heat insulation cold bridges and second window frame aluminum section bars, the first window frame aluminum section bars are connected with thesecond window frame aluminum section bars through the window frame heat insulation cold bridges, and catching grooves are formed above the second window frame aluminum section bars, and connected with aluminum section bar stopping bars through limiting blocks. According to the broken-bridge-type fireproof window, the temperature conduction is reduced through the broken-bridge-type structure, thefireproof performance is improved, the sealing performance is high, and the heat preservation performance for external walls is good.

Description

technical field [0001] The invention relates to the technical field of fireproof windows, in particular to a bridge-broken fireproof window. Background technique [0002] With the rapid development of social economy, the progress that people have made in construction has become more and more obvious. During the use of houses, some buildings need to install fire protection facilities. Among them, fire windows are widely used. Fire windows refer to Windows within, together with the frame meeting the fire stability and fire integrity requirements. On the outer walls of two buildings with insufficient fire separation distance, or between spaces separated by firewalls, when lighting and ventilation are required, fire windows should be used. There are two types of fire windows: one is not only within the specified time Fire windows that maintain integrity and have heat insulation functions; the other is fire windows that maintain integrity within a specified period of time but do...

Problems solved by technology

[0004] The purpose of the present invention is to provide a broken bridge type fireproof window to solve the problem that the existing broken bridge type fireproof window proposed in the above-mentioned background technology is not strong because the sealing performance of the broken bridge aluminum is not strong, resulting in poor sealing performance of the fireproof window. Occasionally, problems such as water seepage may occur
