Description

Technical Field

[0001] This utility model belongs to the technical field of door and window profiles, and specifically relates to a fireproof, soundproof and heat-insulating door and window profile. Background Technology

[0002] Thermally broken aluminum profiles, also known as insulated aluminum alloy profiles, offer superior performance compared to ordinary aluminum alloy profiles. The "bridge" in "thermally broken aluminum" refers to a thermal bridge in materials science, while "broken" signifies breaking the thermal bridge. Specifically, because aluminum alloy is a metal with relatively high thermal conductivity, it can act as a heat transfer bridge when there's a significant temperature difference between indoors and outdoors. Using such a material for doors and windows reduces their thermal insulation performance. Thermally broken aluminum, however, breaks the aluminum alloy in the middle. Current technology uses rigid plastic or PA66 nylon insulation material to connect the broken sections. Since plastic and nylon conduct heat much slower than metal, heat doesn't easily pass through the entire material. However, existing thermally broken aluminum profiles have poor fire resistance, inadequate sound insulation and heat preservation, and are prone to aging.

[0003] Therefore, in response to the above-mentioned technical problems, the design of fireproof, soundproof, and heat-insulating door and window profiles involves placing an aerogel felt layer in the middle of the aluminum alloy profile. The aerogel separates the aluminum alloy profile, achieving the purpose of fireproofing, soundproofing, heat insulation, and preventing aging and cracking. These are technical problems that need to be solved by those skilled in the art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this utility model is to provide a fireproof, soundproof, and heat-insulating door and window profile, which places an aerogel felt layer in the middle of an aluminum alloy profile and separates the aluminum alloy profile with aerogel, thereby achieving the purpose of fireproofing, soundproofing, heat insulation, and preventing aging and cracking.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figure 1 The fireproof, soundproof, and heat-insulating door and window profile disclosed in this embodiment of the present invention includes at least an indoor profile 3 and an outdoor profile 1. An aerogel felt layer 2 is provided between the indoor profile 3 and the outdoor profile 1. The indoor profile 3, the outdoor profile 1, and the aerogel felt layer 2 are fixed together by fasteners. By providing the aerogel felt layer 2 between the indoor profile 3 and the outdoor profile 1, the indoor profile 3 and the outdoor profile 1 can be separated to avoid heat transfer between metals. The aerogel felt layer 2 can effectively improve the fireproof, heat-insulating, and soundproof effects of the door and window profile.

[0025] It should be noted that the interior profile 3 and the exterior profile 1 can be further expanded into specific components of doors and windows such as frames, atriums, and sashes.

[0026] The thermal conductivity of the aerogel felt layer 2 at room temperature is only 1 / 3 to 1 / 5 of that of traditional insulation material layers. Under the same thermal resistance requirements, the thickness can be reduced by 50% to 80%, which significantly saves building space. It still maintains excellent thermal insulation performance in high-temperature environments. It is a flexible material that is easy to cut, and its three-dimensional nanoporous structure can effectively absorb mid-to-high frequency sound waves, resulting in good sound insulation.

[0027] refer to Figure 1 In one embodiment, the fastener includes a screw 5 that passes through the outdoor profile 1, the aerogel felt layer 2 and the outdoor profile 1 in sequence. The screw 5 is threadedly connected to the indoor profile 3 and the outdoor profile 1. The screw 5 can lock the indoor profile 3, the outdoor profile 1 and the aerogel felt layer 2.

[0028] refer to Figure 1 and Figure 2 In one implementation, a heat-insulating sleeve 4 is provided between the outer wall of the screw 5 and the outdoor profile 1, and a heat-insulating pad 6 is provided between the outdoor profile 1 and the aerogel felt layer 2, which is snapped into the heat-insulating sleeve 4. By providing the heat-insulating sleeve 4, the problem of heat transfer due to direct contact between the screw 5 and the outdoor profile 1 can be avoided, further ensuring the heat insulation effect of the door and window profiles. By setting the heat-insulating pad 6 and the heat-insulating sleeve 4, the outdoor profile 1 can be locked, providing support for the aerogel felt layer 2, and avoiding the problem of excessive extrusion pressure between the outdoor profile 1 and the indoor profile 3, which would cause the aerogel felt layer 2 to deform.

[0029] It should be noted that the materials of the heat insulation sleeve 4 and the heat insulation pad 6 can be silicone, polyurethane or rubber, as long as the heat insulation between the screw 5 and the indoor profile 3 or the outdoor profile 1 is achieved.

[0030] refer to Figure 1 After the heat insulation pad 6 is attached to the aerogel felt layer 2, the heat insulation pad 6 will be pressed into the aerogel felt layer 2 due to compression.

[0031] refer to Figure 1 As one implementation method, the diameter of the heat insulation pad 6 is equal to the distance between two adjacent support ribs 8 of the outdoor profile. That is, the size of the heat insulation pad 6 is made large enough to support the aerogel felt layer 2 on the entire surface and avoid deformation of the aerogel felt layer 2.

[0032] It should be noted that the thickness of the heat insulation pad 6 is the same as the thickness of the aerogel felt layer 2, thereby preventing the aerogel felt layer 2 from deforming due to excessive compression.

[0033] refer to Figure 1 In one embodiment, an aluminum strip 9 is provided on the outside of the groove of the outdoor profile 1 away from the aerogel felt layer 2. The aluminum strip 9 is provided with a hook-shaped structure, and a protruding post is provided on the side wall of the outdoor profile 1 for cooperating with the hook-shaped structure. The aluminum strip can be snapped together by providing the hook-shaped structure and the protruding post. The aluminum strip 9 is flush with the outside of the outdoor profile 1. After installation, the aluminum strip is fixed to the side wall of the outdoor profile 1 by cooperating with the hook-shaped structure and the protruding post. The aluminum strip 9 is also made to fit the material of the outdoor profile 1 to ensure aesthetics.

[0034] refer to Figure 1 In one embodiment, the outdoor profile 1 has a through hole for the heat insulation sleeve 4 to pass through. The through hole and the heat insulation sleeve 4 are interference fit, which can ensure that the heat insulation sleeve 4 is not loose after being embedded in the outdoor profile 1 and avoid stress concentration.

[0035] refer to Figure 1 and Figure 2In one embodiment, the outdoor profile 1 has a groove for the screw 5 to pass through on the side away from the aerogel felt layer 2. The inner diameter of the groove is larger than the inner diameter of the through hole. The thermal insulation pad 6 has an abutment ring 7 on the side away from the aerogel felt layer 2, which abuts against the groove. The outer diameter of the abutment ring 7 is larger than the outer diameter of the sleeve at the end of the thermal insulation sleeve 4 that mates with the through hole. The inner diameter of the groove is larger than the inner diameter of the through hole, which provides installation space for the abutment ring 7 of the thermal insulation sleeve 4. The tight fit between the abutment ring 7 and the side wall of the groove forms a double sealing barrier, which effectively prevents moisture or dust from seeping into the interior of the profile from the screw 5 hole. In addition, the outer diameter of the abutment ring 7 is larger than the outer diameter of the thermal insulation sleeve 4, which can cover the edge of the through hole, preventing the edge of the sleeve from lifting due to thermal expansion and contraction, and reducing the risk of sealing failure.

[0036] It should be noted that the heat insulation sleeve 4 and the abutment ring 7 are integrally formed.

[0037] refer to Figure 1 In one embodiment, an adhesive layer is provided between the interior profile 3 and the aerogel felt layer 2. By providing the adhesive layer, the aerogel felt layer 2 can be adhered to the interior profile 3, which facilitates the positioning of the aerogel felt layer 2 and facilitates subsequent assembly.

[0038] refer to Figure 1 In one embodiment, the end of the screw 5 away from the aerogel felt layer 2 is coated with a heat-insulating and waterproof adhesive 10. The heat-insulating and waterproof adhesive 10 is one of silicone adhesive, polyurethane adhesive, acrylic adhesive and modified asphalt-based adhesive. By setting the heat-insulating and waterproof adhesive 10, the screw can be heat-insulated and rust-proofed, further ensuring the heat insulation effect.

[0039] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0040] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
