Aluminum-clad wood fire-resistant window

Abstract

The invention discloses an aluminum-clad wood refractory window. The key points of the technical scheme are that it comprises a window frame, a window sash and a window glass, an aluminum alloy outer frame near the window glass, an aluminum alloy outer mullion near the window glass, and an aluminum alloy outer frame. The side of the window sash close to the window glass is formed with ribs, the side of the wood inner frame close to the window glass, the side of the wood inner mullion close to the window glass and the side of the wood inner sash are all provided with buckles, and the edge of the window glass is clamped on the side of the rib There are steel glass clips between the inner frame of the wood and the outer frame of the aluminum alloy, between the inner frame of the wood and the outer frame of the aluminum alloy, and between the inner sash of the wood and the outer sash of the aluminum alloy. One end of the glass clip is respectively fixed to the wood inner frame, the wood mullion and the wood inner sash, and the other end is pressed to the edge of the window glass, so that the window glass is not easy to shake or fall when exposed to fire.

Description

technical field [0001] The invention relates to a door and window, in particular to an aluminum-clad wood fire-resistant window. Background technique [0002] Under the standard fire resistance test conditions, when one side of the building doors and windows is subjected to fire, it is the ability to prevent the penetration of flames and hot gas within a certain period of time, or the ability of flames to appear on the back side of the fire. According to the requirements of the code, the fire integrity of windows with fire integrity requirements shall be measured according to the test method for non-insulated glass-mounted components in GB / T12513 "Fire Resistance Test Method for Glass Hooks". [0003] The windows of glass curtain walls are mostly made of aluminum alloy window frames. The melting point of aluminum alloy profiles is about 650 degrees Celsius. It is difficult to meet the fire protection standards for external doors and windows composed of commonly used broken b...

Problems solved by technology

[0003] The windows of the glass curtain wall are mostly made of aluminum alloy window frames. The melting point of the aluminum alloy profiles is about 650 degrees Celsius. It is difficult to meet the fire protection standards for the outer doors and windows composed of the commonly used broken bridge aluminum alloy profiles.

When exposed to fire, the aluminum alloy softens, making the window glass prone to shaking or falling outwards
