Broken bridge type steel and aluminium alloy fire-resistant window

Abstract

A broken bridge type steel and aluminium alloy fire-resistant window is characterized by comprising a window frame, window sashes, fire-resistant composite glass, a handle lock and a hinge; the bulk sample of the window has various forms; the window can be divided according to requirements of users at wills; the number and positions of the window sashes can be distributed according to the requirements of the users; and the forms of the window sashes are internal flat-opening forms. The broken bridge type steel and aluminium alloy fire-resistant window has the advantages that the broken bridgetype steel and aluminium alloy fire-resistant window is a novel window, is mounted on an external wall of a building and has a building energy saving function and a building fire-resistant function; the structure is simple and practical; the appearance of the broken bridge type steel and aluminium alloy fire-resistant window has no difference with the appearance of a common window structure; the broken bridge type steel and aluminium alloy fire-resistant window is energy-saving and fire-resistant on the internal side of the structure; the application is wide; the use is simple and convenient;the broken bridge type steel and aluminium alloy fire-resistant window is easy to master; multiple performances can be integrated; and performances such as the energy-saving property, the heat insulation property, weather resistance, beauty, the firefighting property and fire resistance are all taken into consideration.

Description

[0001] (1) Technical field: [0002] The invention relates to a bridge-broken steel-aluminum alloy fire-resistant window, which is a new type of window, which is installed on the outer wall of a building and has the functions of building energy saving and building fire prevention. It can meet the requirements of building energy saving. , and at the same time, when a fire occurs outside the building or in a building other than the fire-resistant window, it can play the role of isolating smoke and fire within a certain period of time. [0003] (two) background technology: [0004] At present, regardless of the height of domestic buildings, broken bridge aluminum windows or plastic-steel windows with energy-saving and thermal insulation functions are commonly used on the exterior walls of buildings. The composition is aluminum or plastic, and the refractory temperature is not high. As far as aluminum with good refractory is concerned, when the temperature reaches 660°C (in the eve...

Problems solved by technology

[0004] At present, regardless of the height of domestic buildings, broken bridge aluminum windows or plastic-steel windows with energy-saving and thermal insulation functions are commonly used on the exterior walls of buildings. The composition is aluminum or plastic, and the refractory temperature is not high. As far as aluminum with good refractory is concerned, when the temperature reaches 660°C (in the event of a fire, it usually takes 8 to 9 minutes to reach this temperature), the aluminum will melt.
