The glass assembly is clamped on the inner side of the aluminum alloy window frame, and sealing strip assemblies are tightly attached to both sides of the edge of the glass assembly. By arranging the sealing strip assemblies on both sides of the glass assembly, the connection can be sealed. At the same time, the internal gap of the sealing strip assembly is filled with sealant.

[0004] The above solution solves the technical problems raised in its background technology, but in actual application, the above solution still has certain defects. For example, the above device installs the fireproof glass between two sealing strip assemblies. First, the sealing strip assembly is an elastic part, which leads to low stability of the fireproof glass after installation. Secondly, when a fire occurs, the high temperature will destroy the integrity of the elastic part, which may cause the fireproof glass to fall off. Therefore, how to improve the fire resistance integrity while ensuring thermal insulation performance is a technical problem that needs to be solved at present. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a low-energy aluminum alloy combined fire-resistant door and window, comprising an aluminum alloy window frame and fire-resistant glass, wherein the aluminum alloy window frame comprises a base and two support frames located within the base, a flame-retardant elastic block is connected between the two support frames, a cavity is defined in the middle of the flame-retardant elastic block, and the cavity is filled with a heat-insulating filler;

[0017] The low-energy consumption aluminum alloy combined fire-resistant doors and windows effectively reduce the influence of metal connectors on the overall heat conduction performance of fire-resistant doors and windows by rationally designing the processing and installation structure of U-shaped support steel, thereby achieving low energy consumption of fire-resistant doors and windows; through the inclined cavity, heat-expanding material, inclined plate and support member, when a fire occurs outside, the high temperature causes the heat-expanding material to expand due to heat, and the heat-expanding material generates an oblique upward extrusion force on the top of the support frame, and the top frame of the support frame deforms inward, driving the oblique support plate and the extrusion plate to generate an extrusion force on the fire-resistant glass, thereby clamping the fire-resistant glass between the two extrusion plates, improving the stability of the fire-resistant glass, and effectively preventing the aluminum alloy window frame from falling off due to heat deformation.

[0018] At the same time, an open plate and an open contraction plate are provided, and adhesive is filled into the first filling cavity, and the adhesive enters the second filling cavity through the glue injection hole.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 2 As shown, the utility model provides a technical solution: a low-energy aluminum alloy combined fire-resistant door and window, comprising an aluminum alloy window frame 1 and fire-resistant glass 2. The outer surface of the aluminum alloy window frame 1 is coated with heat-insulating paint and flame-retardant material to improve the fire resistance of the aluminum alloy window frame 1 body.

[0024] like Figure 2 As shown, the aluminum alloy window frame 1 includes a base 101 made of aluminum alloy material and two support frames 102 located in the base 101. The bottom of the support frame 102 is connected to the base 101 by a special-shaped groove, and the middle part of the support frame 102 is fixed to the base 101 by end welding points. A flame retardant elastic block 3 is connected between the two support frames 102, and a cavity is opened in the middle of the flame retardant elastic block 3, and the cavity is filled with thermal insulation filler 301. The setting of the flame retardant elastic block 3 improves the fire resistance of the combined fire-resistant doors and windows. The thermal insulation filler 301 can better block heat transfer and reduce indoor heat loss, so that the doors and windows have the effect of energy saving and low energy consumption.

[0025] An upwardly inclined cavity is provided at the top of the support frame 102, and the cavity is filled with a heat-expandable material 104. In order to reduce the weight of the combined fire-resistant door and window, thereby facilitating installation and transportation, the heat-expandable material 104 in this solution is preferably a lightweight expanded rubber. The heat-expandable material 104 can be expanded rubber particles or expanded rubber customized according to the shape of the inclined cavity.

[0026] An inclined plate 105 is formed at the top of the support frame 102, and the angle between the inclined plate 105 and the fireproof glass 2 is 30-60 degrees. A support member for supporting the side of the fireproof glass 2 is provided on the side of the inclined plate 105, wherein the support member includes an inclined support plate 6 and an extrusion plate 7 fixed at the end of the inclined support plate 6, and the angle between the inclined support plate 6 and the fireproof glass 2 is 30-60 degrees, and after installation, the side of the extrusion plate 7 contacts the side of the fireproof glass 2.

[0027] In order to prevent water or dust from entering the gap between the base 101 and the support frame 102, a gap is formed between the top plate of the support frame 102 and the base 101, and a sealing strip 103 made of rubber material is installed in the gap. Since the sealing strip 103 has a certain elasticity and there is an interference fit between the sealing strip 103 and the gap, this not only achieves the above-mentioned sealing effect, but also increases the friction between the support frame 102 and the sealing strip 103, thereby increasing the stability of the support frame 102 after installation.

[0028] In order to prevent the fire-resistant glass 2 from being damaged due to the deformation of the flame-retardant elastic block, a U-shaped support steel 4 is set on the top of the two support frames 102. The fire-resistant glass 2 is placed on the top of the U-shaped support steel 4, and flame-retardant paint is applied on the surface of the U-shaped support steel to effectively reduce the influence of metal connectors on the overall thermal conductivity performance of fire-resistant doors and windows, thereby achieving low energy consumption of fire-resistant doors and windows.

[0029] Since the installation groove formed by the fireproof glass 2 and the two extrusion plates 7 is a clearance fit, in order to prevent the fireproof glass 2 from shaking after installation, an open plate 801 is fixed at the top of the extrusion plate 7, and a first filling cavity is formed between the open plate 801 and the fireproof glass 2, and the first filling cavity is filled with adhesive. In order to increase the bonding surface and improve the stability of the fireproof glass 2, an open contraction plate 802 is fixed at the bottom end of the extrusion plate 7, and a second filling cavity is formed between the open contraction plate 802 and the fireproof glass 2. In addition, a number of glue injection holes 803 are opened on the plate body of the extrusion plate 7.

[0030] Specifically, the fireproof glass 2 and related components are Figure 2 Perform modular installation by filling the first filling cavity with adhesive, which then flows into the second filling cavity through the adhesive injection hole 803. After a period of time, both the first filling cavity and the second filling cavity are filled with adhesive. After the adhesive solidifies, the modular door and window is placed in the door frame and fixed.

[0031] When a fire occurs outside, due to the high external ambient temperature, the thermal expansion material 104 expands due to the heat, and the thermal expansion material 104 generates an oblique upward extrusion force on the top of the support frame 102. The top frame of the support frame 102 deforms inward, driving the oblique support plate 6 and the extrusion plate 7 to form an extrusion force on the fireproof glass 2, thereby clamping the fireproof glass 2 between the two extrusion plates 7, improving the stability of the fireproof glass 2, and effectively preventing the aluminum alloy window frame 1 from falling off due to heat deformation.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
