Description

Insulated Aluminum Alloy Fire Resistant Windows

technical field

The utility model relates to the technical field of doors and windows, in particular to a heat-insulating aluminum alloy fire-resistant window.

Background technique

Heat-insulated aluminum alloy doors and windows refer to mechanically connecting the aluminum alloy profiles on both sides of the indoor and outdoor sides with low heat transfer coefficient reinforced nylon heat-insulating strips to obtain frame profiles with excellent thermal insulation performance, and then equipped with insulating glass And the optimized design of the sealing treatment measures, so as to make the aluminum alloy doors and windows with thermal insulation performance.

Heat-insulated aluminum alloy doors and windows, taking into account the advantages of both plastic and aluminum alloy materials, have the advantages of environmental protection and energy saving, beautiful appearance, high wind pressure resistance, good water and air tightness, and strong corrosion resistance.

According to the statistics of relevant departments, in terms of my country's architectural door and window product market, aluminum door and window products account for 55%, the largest proportion. It can be proved that it has been fully recognized by the market.

However, with the successive implementation of the national standard "Code for Fire Protection of Buildings" GB50016-2014 and "General Technical Conditions for Building Curtain Walls, Doors and Windows" GB/T 31433-2015, the state has put forward higher requirements for the fire integrity of doors and windows on the exterior walls of buildings. requirements. Due to the relatively weak ability of aluminum alloy doors and windows to resist thermal deformation, in a fire environment, the temperature is as high as 600-800°C. In a short period of time, the surface close to the fire will burn and fall off quickly, which will cause the failure of the fire resistance function of doors and windows, and aggravate the fire trend. Indoor spread cannot meet the requirements of national standards for fire resistance.

The market demand urgently needs a building door and window product or technology that not only guarantees the basic physical properties and energy-saving performance requirements of doors and windows, but also meets the fire resistance integrity of doors and windows not less than 0.5 hours.

detailed description

In order to enable those skilled in the art to better understand the solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1, a heat-insulating aluminum alloy fire-resistant window provided by the utility model includes an aluminum alloy window frame 1, an aluminum alloy window sash 2 and a fireproof hollow glass 3 arranged on the top of the aluminum alloy window sash 2, the aluminum alloy window frame 1 and the aluminum alloy window sash 2 The aluminum alloy window sash 2 is connected through hardware connectors; an inner lining 5 is arranged inside the aluminum alloy window sash 2 .

In Fig. 1, the left side is the indoor side, and the right side is the outdoor side, the chamber of the aluminum alloy sash 2 and the aluminum alloy window frame 1 close to the outdoor side is filled with heat absorbing material 6, preferably in the chamber located in the middle Heat-absorbing material 6 is also filled; in the notch between the aluminum alloy window frame 1 and the aluminum alloy window sash 2, the first heat-expandable seals 7 (including four in Fig. 1 ), when a fire occurs and heat, the first The heated expansion seal 7 expands to block the entry of smoke and heat flow. The first heated expansion seal 7 can also be used in combination with the fireproof rubber strip in the notch, for example, it is arranged on the surface of the fireproof rubber strip 4 in the notch; the edge of the fireproof insulating glass 3 The gap with the aluminum alloy window sash 2 is provided with a fireproof structure.
