Abstract

The utility model discloses a stretch-proof anti-shearing heat insulation door and window section bar which comprises an inner window section bar, an outer window section bar, heat insulation strips, a heat insulation cavity, heat insulation glue, heat insulation strip clamping grooves and sawtooth joint faces, the inner window section bar and the outer window section bar are connected in a clamping mode through at least one pair of heat insulation strips, and the heat insulation cavity is formed between the heat insulation strips in a surrounding mode. The heat insulation cavity is filled with heat insulation glue, and at least one pair of parallel heat insulation strip clamping grooves are formed in the positions, clamped with the heat insulation strips, of the inner window profile and the outer window profile respectively.

Description

Technical Field

[0001] The utility model relates to the field of door and window profiles, in particular to a tensile and shear-resistant heat-insulating door and window profile. Background Art

[0002] The inner and outer profiles of thermal insulation doors and windows are usually connected by thermal insulation strips. Filling the gaps between the thermal insulation strips with thermal insulation glue can enhance the sealing performance between the thermal insulation strips and the profiles, while also enhancing the tensile and shear resistance. However, since the sealant is easily loosened by external forces, this leads to the recurrence of water seepage and distortion problems. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a tensile and shear-resistant thermal insulation door and window profile. Due to the addition of a serrated joint surface, the thermal insulation glue in the thermal insulation cavity is shaped into a tooth surface, thereby establishing a bite force between the thermal insulation glue and the inner and outer profiles, thereby effectively suppressing the problem of the thermal insulation glue loosening, maintaining the sealing and shear resistance performance for a long time, and effectively improving the service life of the product.

[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a tensile and shear-resistant thermal insulation door and window profile, including an inner window profile, an outer window profile, an insulation strip, an insulation cavity, insulation glue, an insulation strip slot, and a serrated joint surface. The inner window profile and the outer window profile are connected by at least one pair of insulation strips, and an insulation cavity is formed between the insulation strips. The insulation cavity is filled with insulation glue. The inner window profile and the outer window profile are respectively provided with at least one pair of insulation strip slots parallel to each other at the connection with the insulation strips. The inner window profile and the outer window profile are each provided with a serrated joint surface between the insulation strip slots. The insulation glue covers the serrated joint surface and forms interlocking serrations after curing.

[0005] In a preferred embodiment of the present invention, the serration engagement surface is concave.

[0006] In a preferred embodiment of the present invention, the serrated engagement surface is convex.

[0007] The beneficial effect of the utility model is that the utility model provides a tensile and shear-resistant heat-insulating door and window profile, which has a serrated joint surface, so that the heat-insulating glue in the heat-insulating cavity is shaped into a tooth surface, thereby establishing a bite force between the heat-insulating glue and the inner and outer profiles, thereby effectively suppressing the problem of the heat-insulating glue loosening, maintaining the sealing and shear resistance for a long time, and effectively improving the service life of the product.

[0011] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] like Figure 1 , 2 As shown, the embodiment of the utility model includes:

[0013] A tensile and shear-resistant heat-insulating door and window profile, comprising an inner window profile 1, an outer window profile 2, an insulation strip 3, an insulation cavity 4, insulation glue 5, an insulation strip slot 6, and a serrated joint surface 7. The inner window profile 1 and the outer window profile 2 are connected by at least one pair of insulation strips 3, the insulation strips 3 surround an insulation cavity 4, the insulation cavity 4 is filled with insulation glue 5, the inner window profile 1 and the outer window profile 2 are respectively provided with at least one pair of insulation strip slots 6 parallel to each other at the connection with the insulation strips 3, the inner window profile 1 and the outer window profile 2 are each provided with a serrated joint surface 7 between the insulation strip slots 6, the insulation glue 5 covers the serrated joint surface 7 and forms interlocking serrations after curing.

[0014] The serrated joint surface 7 is concave.

[0015] Furthermore, the serrated joint surface 7 is convex.

[0016] In order to effectively solve the problem of the thermal insulation glue 5 being loose, this product adds a serrated joint surface 7 at the bridge of the inner window profile 1 and the outer window profile 2. During the production process of doors and windows, the thermal insulation glue 5 injected into the thermal insulation cavity 4 fully covers the serrated joint surface 7 and can solidify to form an engaging serration, which can be engaged with the serrated joint surface 7, thus solving the problem of the thermal insulation glue 5 being loose. This ensures that the door and window system can be waterproof, tensile and shear resistant for a long time.

[0017] This product has the following beneficial effects:

[0018] 1. The heat insulation cavity adopts internal serration or external serration design.

[0019] 2. When the PU heat insulating adhesive 5 is poured in, the heat insulating adhesive 5 can be well connected with the inner serrations and the outer serrations, thereby improving the transverse tensile strength and longitudinal shear strength of the heat insulating profile.

[0020] 3. Improved production efficiency.

[0021] In summary, the utility model provides a tensile and shear-resistant heat-insulating door and window profile. Due to the addition of the serrated joint surface 7, the heat-insulating glue 5 in the heat-insulating cavity 4 is shaped into a tooth surface, thereby establishing a bite force between the heat-insulating glue 5 and the inner and outer profiles, thereby effectively suppressing the problem of the heat-insulating glue 5 loosening, maintaining the sealing and shear resistance for a long time, and effectively improving the service life of the product.
