Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile heat insulation structure, and particularly to a water seepage prevention heat insulation profile structure. BACKGROUND

[0002] In the field of construction, heat insulation profiles are widely used in components such as doors, windows and curtain walls because they can effectively block heat transfer and improve building energy efficiency. The existing heat insulation profiles are usually assembled by aluminum alloy profiles (first profile, second profile) and heat insulation strips. The connection method is usually as follows: a clamping groove is provided on the profile, the end of the heat insulation strip is inserted, and then the "hammer head" of the profile is plastically bent by mechanical external force, and the "supporting part" is clamped to tightly hold the heat insulation strip, forming an overall structure.

[0003] However, the traditional structure has the following defects: Insufficient sealing performance: after the hammer head is bent, a small gap is easily formed between the hammer head and the outer peripheral surface of the heat insulation strip due to processing errors or assembly gaps, which causes rainwater to seep or air convection, reducing the waterproof and heat insulation effects; Poor heat insulation reliability: a "thermal bridge" is easily formed at the gap, and heat is transferred through the gap, weakening the blocking effect of the heat insulation strip; Low structural stability: after long-term use, the clamping force of the hammer head and the heat insulation strip may be relaxed due to material fatigue, further expanding the gap.

[0004] Therefore, there is an urgent need for an improved heat insulation profile structure that can effectively fill the assembly gap and improve the sealing and heat insulation performance. SUMMARY

[0005] The present application aims to overcome the shortcomings of the prior art and provide a water seepage prevention heat insulation profile structure that optimizes the sealing design and improves the waterproof, heat insulation performance and structural durability.

[0006] In order to achieve the above-mentioned purpose, the present application provides a water seepage prevention heat insulation profile structure, which comprises a heat insulation strip between a first profile and a second profile, the first profile and the second profile each having a hammer head and a supporting part, the hammer head and the supporting part forming a clamping groove for connecting the end of the heat insulation strip; after the end of the heat insulation strip is placed in the clamping groove, the hammer head is plastically bent inward by applying external force, and the supporting part clamps the end of the heat insulation strip; at least one sealing part with elastic deformation characteristics is provided on the heat insulation strip, the sealing part protrudes from the outer peripheral surface of the heat insulation strip; each hammer head is pressed against the sealing part after being bent, so that the hammer head and the outer peripheral surface of the heat insulation strip clamp the sealing part, and the sealing part deforms elastically to fill the gap between the hammer head and the heat insulation strip.

[0007] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0008] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0009] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0010] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0011] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0012] Further, the outer peripheral surface of the heat insulation strip is provided with a sealing portion on both sides, wherein the two sealing portions are respectively used for the hammer head of the first profile and the hammer head of the second profile to be pressed and contacted.

[0013] The application has the advantages that: 1) efficient water seepage prevention: the sealing portion is elastically deformed under the pressing of the hammer head and the heat insulation strip, effectively filling the assembly gap and blocking the rainwater seepage path; 2) strengthening the heat insulation performance: the sealing portion avoids air convection after filling the gap, reduces the "thermal bridge" effect, and improves the overall heat insulation coefficient; 3) improving the structural stability: the elastic sealing portion can compensate for the material fatigue gap during long-term use, maintaining the stability of the clamping force; 4) convenient assembly: the sealing portion is pre-assembled with the heat insulation strip through the penetrating groove or the fixing groove, and no additional assembly process is required subsequently, simplifying the production process.

[0019] In order to more fully set forth the present application, the following will be described in detail in conjunction with the drawings. The drawings show the preferred embodiments of the present application. However, it is worth noting that the present application is not limited to these specific forms, it can be implemented in various ways. The purpose of providing these embodiments is to enable the reader to have a more in-depth understanding of the present application.

[0020] Referring to the drawings Figures 1-4 As shown in the drawings, in the present embodiment, a water seepage prevention and heat insulation profile structure comprises a heat insulation strip 1 interposed between a first profile and a second profile, wherein the cross-sectional shape of the heat insulation strip 1 is in a rectangular structure, and the two side ends thereof correspondingly have a wedge structure, and is generally made of PA66 material. The first profile and the second profile both have a hammer head 2 and a supporting part 3, and the hammer head 2 and the supporting part 3 are configured to form a clamping slot for the end part of the heat insulation strip 1 to be connected, wherein after the end part of the heat insulation strip 1 is placed in the clamping slot, the hammer head 2 is plastically bent to the inside of the clamping slot by applying an external force, and the supporting part 3 clamps the end part of the heat insulation strip 1.

[0021] In the present embodiment, the heat insulation strip 1 is provided with at least one sealing part 4 having elastic deformation characteristics, and the mechanical pressure after the hammer head 2 is bent causes the sealing part 4 to have controllable elastic deformation, thereby achieving "self-adaptive filling" of the gap. Specifically, the sealing part 4 of the present embodiment protrudes from the outer circumferential surface of the heat insulation strip 1, ensuring that the hammer head 2 can contact the sealing part 4 after being bent; each of the hammer heads 2 is pressed against the sealing part 4 after being bent, so that the hammer head 2 and the outer circumferential surface of the heat insulation strip 1 clamp the sealing part 4, and the sealing part 4 is elastically deformed to fill the gap between the hammer head 2 and the heat insulation strip 1, that is, the plastic deformation of the hammer head 2 provides a lasting clamping force, and the elastic deformation of the sealing part 4 compensates for the assembly error and the gap, so that the sealing part 4 forms a "line-surface" contact with the hammer head 2 and the outer circumferential surface of the heat insulation strip 1, thereby blocking the water seepage and air flow path, and achieving the effects of water seepage prevention and heat insulation.

[0022] In the present embodiment, the outer circumferential surface of the heat insulation strip 1 is provided with one sealing part 4 on each side, wherein the two sealing parts 4 are respectively pressed against the hammer head 2 of the first profile and the hammer head 2 of the second profile. In order to facilitate understanding, the following will be further explained and described in conjunction with specific implementation cases one and two.

[0023] Implementation case one: referring to the drawings Figure 1As shown, the heat insulation strip 1 is provided with an arc-shaped through slot 11 on both sides of the outer circumferential surface along the length direction, and the sealing part 47 is a columnar structure made of EPDM rubber material, and the cross section is matched with the through slot 118. During assembly, the sealing part 47 is inserted into the through slot 118, so that the sealing part 47 partially protrudes from the outer circumferential surface of the heat insulation strip 13; then the end part of the heat insulation strip 13 is inserted into the clamping groove 6 (formed by the hammer head part 24 and the supporting part 35) of the first profile 1 and the second profile 2, and the hammer head part 24 is plastically bent inward by the rolling equipment until the hammer head part 24 is in extrusion contact with the sealing part 47. At this time, the sealing part 47 is elastically deformed under the clamping of the hammer head part 24 and the heat insulation strip 13, and is filled into the gap between the two, thereby forming a waterproof and heat insulation sealing structure.

[0024] Case two: refer to the attached Figure 2 As shown, the heat insulation strip 1 is provided with a "C"-shaped through slot 11 on both sides of the outer circumferential surface along the length direction. The sealing part 47 is made of EPDM rubber material and has an "L"-shaped cross section, and the horizontal end part is a wedge-shaped structure. During assembly, the horizontal end parts of the two sealing parts 4 are respectively inserted into the two through slots 11 and are clamped with the "C"-shaped through slot 11 by the wedge-shaped horizontal end part, so that the sealing part 4 is fixed to the heat insulation strip 1, and the vertical end part protrudes from both sides of the outer circumferential surface of the heat insulation strip 13. After the hammer head part 2 is bent, the vertical end part of the sealing part 4 is extruded and deformed to fill the gap between the hammer head part 2 and the heat insulation strip 1, thereby forming a waterproof and heat insulation sealing structure. The wedge-shaped structure design can enhance the connection strength of the sealing part 4 and the through slot 11, and avoid falling off.

[0025] In this embodiment, other structure forms can also be used between the heat insulation strip 1 and the sealing part 4. In order to facilitate understanding, the following will be further explained in combination with specific case three. Case three: refer to the attached Figure 3 As shown, the outer circumferential surface of the heat insulation strip 1 is provided with a fixed slot 12 with an upper opening in the middle, and the sealing part 4 is formed with a connecting clamping block 41 which is inserted and clamped with the fixed slot 12, and the sealing part 4 is integrally extended to both sides of the heat insulation strip 1 to form a part for extrusion contact of the hammer head part 2 of the first profile and the hammer head part 2 of the second profile. During assembly, the connecting clamping block 41 is inserted into the fixed slot 12 to realize the pre-fixing of the sealing part 4, and the two side contact parts correspond to the hammer head parts 2 of the first profile and the second profile respectively. After the hammer head part 2 is bent, the two side contact parts are simultaneously extruded and deformed, thereby realizing bidirectional sealing.

[0026] In this embodiment, other structure forms can also be used between the heat insulation strip 1 and the sealing part 4. In order to facilitate understanding, the following will be further explained in combination with specific case four. Case four: refer to the attached Figure 4As shown, the outer peripheral surface of the heat insulation strip 1 is protruded in the middle to form a fixing block 13, and the bottom of the sealing part 4 is formed with a connecting groove 42 which is connected with the fixing block 13. The sealing part 4 is extended to the two sides of the heat insulation strip 1 to form a contact part for the hammer head 2 of the first profile and the hammer head 2 of the second profile. During assembly, the connecting groove 42 and the fixing block 13 are connected to realize the pre-fixing of the sealing part 4, and the two contact parts are respectively corresponding to the hammer head 2 of the first profile and the hammer head 2 of the second profile. After the bending of the hammer head 2, the two contact parts are simultaneously extruded and deformed to realize the bidirectional sealing. In addition, the cross-sectional shape of the fixing block 13 can be a "T" structure or other derived shapes, which are not limited here, as long as the stable connection between the connecting groove 42 and the fixing block 13 can be realized.

[0027] In summary, the differences and technical effects compared with the prior art are as follows: By changing "passive dependence on machining precision" to "active use of elastic deformation", the "dynamic self-maintenance" of the sealing performance is realized through structural design, which solves the technical bottleneck of "rigid connection cannot adapt to error and relaxation" in traditional structure. In addition, by pre-assembling the sealing part 4 on the heat insulation strip 1, the difficulty of subsequent assembly of the heat insulation strip 1 can be avoided, the production process is simplified, and the assembly efficiency is improved.

Any skilled person in the art can make more possible changes and decorations to the technical solution of the present application by using the disclosed technical content, or make modifications without departing from the scope of the technical solution of the present application, which are equivalent embodiments of the present application. Therefore, any equivalent changes within the scope of the technical solution of the present application, according to the idea of the present application, should be covered by the protection scope of the present application.
