AI Technical Summary
The thermal break strips in existing thermal break structures are prone to deformation, leading to thermal insulation failure, and current technologies cannot effectively solve this problem.
A filler strip made of EPDM rubber with low thermal conductivity is filled between the insulation strips. The filler strip is supported by the compression of the inner wall of the insulation strip through the support arm of the filler strip, forming an independent sealed cavity to compensate for the slight deformation of the insulation strip. Stable fixation is achieved by using arc-shaped protrusions and grooves.
It effectively reduces heat convection and heat radiation, ensures the thermal break effect, compensates for the deformation of the thermal break strip, improves sealing, and reduces the heat radiation from the outdoor profile to the indoor profile.

Abstract
Description
Technical Field
[0001] This utility model relates to a thermal insulation profile with thermal insulation filling, belonging to the technical field of building doors and windows. Background Technology
[0002] With the continuous development of technology, more and more building door and window profiles are using thermal break structures, which are widely recognized by consumers for their excellent thermal insulation performance. Existing thermal break structures typically use two parallel thermal break strips inserted between the interior and exterior profiles to block heat transfer. However, since the thermal break strips are non-metallic, they are prone to deformation over time, leading to thermal break failure. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a thermal insulation profile with thermal insulation filling, wherein the thermal insulation profile with thermal insulation filling has deformable filling strips in two parallel thermal insulation strips, thereby supplementing the deformation of the thermal insulation strips and ensuring the overall thermal break insulation effect.
[0004] To solve the above problems, the specific technical solution of this utility model is as follows: a thermal insulation profile with insulation filling, wherein two trapezoidal grooves are respectively provided on the corresponding end faces of the indoor profile and the outdoor profile, and a thermal insulation strip is connected to each pair of corresponding trapezoidal grooves; a filling rubber strip is provided in the thermal insulation cavity formed by the two thermal insulation strips, and at least one rubber strip support arm is provided on both sides, and the rubber strip support arm is squeezed and supported on the inner wall of the thermal insulation strip.
[0005] The filling strip has a U-shaped opening at one end; a positioning strip is provided on the inner surface of the interior profile, and the positioning strip is located between two trapezoidal grooves; the U-shaped opening of the filling strip is inserted into the positioning strip.
[0006] The contact end between the rubber strip support arm and the filling rubber strip has a rounded chamfer.
[0007] The rubber strip support arm is tilted towards the outdoor profile.
[0008] The inner walls of the U-shaped opening of the filling strip are symmetrically provided with arc-shaped protrusions, and arc-shaped grooves are provided at corresponding positions on both sides of the positioning strip. The arc-shaped protrusions are engaged in the arc-shaped grooves of the positioning strip.
[0009] The filler strip is made of EPDM rubber, which has low thermal conductivity.
[0010] The thermal insulation profile with insulation filling in this application adopts the above-described structure and has the following advantages:
[0011] 1. The filling strip is equipped with a strip support arm, which is squeezed with the heat insulation strip to form several independent sealed cavities, thereby further reducing heat convection and heat radiation inside the cavity;
[0012] 2. Because the rubber strip support arm is an inclined structure and is squeezed and supported on the inner wall of the heat insulation strip, it can effectively compensate for the slight deformation of the heat insulation strip and ensure the sealing effect.
[0013] 3. The filling strip is filled into the insulation cavity between the two insulation strips and completely wraps the positioning strip to reduce the heat radiation from the outdoor profile to the indoor profile. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of this application.
[0015] Figure 2 This is a schematic diagram of the filling adhesive strip. Detailed Implementation
[0016] like Figure 1 As shown, a thermal insulation profile with insulation filling has two trapezoidal grooves 3 on the corresponding end faces of the indoor profile 1 and the outdoor profile 2, and each pair of trapezoidal grooves 3 are connected to a thermal insulation strip 4. A filling adhesive strip 6 is provided within the thermal insulation cavity formed by the two thermal insulation strips 4, and at least one adhesive strip support arm 7 is provided on each side. In this embodiment, two adhesive strip support arms 7 are used, which are pressed and supported against the inner wall of the thermal insulation strip 4. An independent cavity is formed between each pair of adjacent adhesive strip support arms 7 and the thermal insulation strip 4, reducing heat radiation between the thermal insulation strips 4.
[0017] The filling strip 6 has a U-shaped opening at one end; a positioning strip 5 is provided on the inner surface of the indoor profile 1, and the positioning strip 5 is located between two trapezoidal grooves 3; the U-shaped opening of the filling strip 6 is inserted and matched with the positioning strip 5, thereby ensuring that the filling strip 6 is fixed in the center position.
[0018] The contact end between the adhesive strip support arm 7 and the filling adhesive strip 6 has a rounded chamfer, which not only ensures repeated contact with the filling adhesive strip 6, but also makes the contact area smooth and will not damage the filling adhesive strip 6.
[0019] like Figure 2 As shown, the inner walls of the U-shaped opening of the filling strip 6 are symmetrically provided with arc-shaped protrusions 8, and arc-shaped grooves are provided at corresponding positions on both sides of the positioning strip 5. The arc-shaped protrusions 8 are engaged in the arc-shaped grooves of the positioning strip 5.
[0020] To facilitate the movement of the filling strip 6 into the cavity between the two insulation strips 4 and its insertion into the positioning strip 5, the strip support arm 7 is inclined towards the outdoor profile 2.
[0021] To reduce thermal conductivity, the filler strip 6 is made of EPDM rubber, a material with low thermal conductivity.
