Description

Technical Field

[0001] The utility model relates to the technical field of wall panel sealing, in particular to a sealing structure for curtain wall panel joints. Background Art

[0002] At present, curtain wall panels are widely used in the field of building decoration due to their advantages such as convenient installation, energy conservation, environmental protection, and good appearance. However, when curtain wall panels are installed, there are certain gaps in the butt-jointed connection parts, and they cannot be tightly connected. There are gaps between adjacent curtain wall panels, which easily lead to problems such as water leakage and poor sound insulation of curtain wall panels.

[0003] At present stage, whether it is a glass curtain wall, a metal curtain wall or a stone curtain wall, they are all installed on the main keel or secondary keel, and the gap treatment method between adjacent curtain wall panels is to fill a foam rubber strip and then apply weather-resistant glue. This treatment method is not only time-consuming and laborious, but also limited by the operation level of workers, and the construction quality has a large discreteness. In addition, during the use of the glue joint, due to reasons such as the deformation of the curtain wall panel, the glue may break away from the gap between the curtain wall panels, making it difficult to ensure the waterproof, heat insulation and sealing effects. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a sealing structure for curtain wall panel joints, which realizes the waterproof, heat insulation and sealing effects of curtain wall panels through an elastic seal, and is convenient for disassembling and replacing the elastic seal, which is beneficial to ensuring the sealing effect of the elastic seal on the gap between curtain wall panels.

[0005] The technical solution for the utility model to solve the above technical problems is as follows:

[0006] A sealing structure for curtain wall panel joints includes an elastic seal, the elastic seal is detachably connected to the gap between two adjacent curtain wall panels, the elastic seal includes a connected connecting part and a sealing part, both the connecting part and the sealing part are in contact with the curtain wall panel, and the sealing part is used for sealing the gap between two adjacent curtain wall panels.

[0007] The beneficial effect of adopting the above technical solution is that the operator presses the connecting part of the elastic seal and inserts the elastic seal into the gap between two adjacent curtain wall panels, so that both the connecting part and the sealing part are in contact with the curtain wall panel, realizing the stable connection between the elastic seal and the curtain wall panel. At the same time, the sealing part can seal the gap between two adjacent curtain wall panels, realizing the waterproof, heat insulation and sealing effects of curtain wall panels; when the elastic seal ages during long-term use, the operator pulls the elastic seal to deform it, and then the elastic seal can be separated from the curtain wall panel, and further the elastic seal can be disassembled and replaced, which is beneficial to ensuring the sealing effect of the elastic seal on the gap between curtain wall panels.

[0008] Further, the connecting portion includes a support bar and a plurality of limiting bars. The limiting bars are connected to both sides of the support bar, and the support bar is connected to the sealing portion.

[0009] The beneficial effect of adopting the above technical solution is that when connecting the elastic seal to the curtain wall panel, the operator presses the plurality of limiting bars on the connecting portion of the elastic seal, so that the connecting portion gradually enters from the gap between two adjacent curtain wall panels. During this process, the degree of elastic deformation of the support bar is relatively small, and the degree of elastic deformation of the limiting bar is relatively large because there is a certain gap between the limiting bars, making it easier to undergo elastic deformation, which is beneficial to improving the smoothness of the connection between the elastic seal and the curtain wall panel.

[0010] Further, the limiting bars are inclined towards the sealing portion.

[0011] The beneficial effect of adopting the above technical solution is that the connection process between the elastic seal and the curtain wall panel is relatively smooth, and the separation process between the elastic seal and the curtain wall panel is relatively difficult, which is beneficial to improving the smoothness of the connection between the elastic seal and the curtain wall panel, and at the same time makes the elastic seal not easily fall off from the gap between two adjacent curtain wall panels.

[0012] Further, a plurality of the limiting bars are all in contact with the curtain wall panel.

[0013] The beneficial effect of adopting the above technical solution is that it increases the contact area between the connecting portion and the curtain wall panel, thereby improving the stability of the connection between the elastic seal and the curtain wall panel, and making the elastic seal not easily fall off from the gap between two adjacent curtain wall panels.

[0014] Further, the end of the support bar away from the sealing portion is in contact with the main keel.

[0015] The beneficial effect of adopting the above technical solution is that the connecting portion is in contact with both the curtain wall panel and the main keel at the same time, improving the stability of the connection between the elastic seal and the curtain wall panel.

[0016] Further, the limiting bar close to the sealing portion abuts against the side of the curtain wall panel facing the main keel.

[0017] The beneficial effect of adopting the above technical solution is that while the limiting bar is in contact with the curtain wall panel, the elastic seal is not easily fall off from the gap between two adjacent curtain wall panels.

[0018] Further, the cross-section of the sealing portion is arranged in an arc structure.

[0019] The beneficial effect of adopting the above technical solution is that the arc-shaped sealing portion fits more closely with the gap of the curtain wall panel, which is beneficial to improving the waterproof, heat insulation and sealing effects on the curtain wall panel.

[0020] Further, the limiting strip is integrally connected to the supporting strip, and the supporting strip is integrally connected to the sealing portion.

[0021] The beneficial effect of adopting the above technical solution is that the elastic seal is a whole structure, which can reduce the damage of the elastic seal and is beneficial to improving the service life of the elastic seal. Description of the Drawings

[0025] The following combines the attached Figure 1-2 The principles and features of the present invention are described. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Embodiment 1 of the present invention discloses a sealing structure for curtain wall panel joints.

[0027] Embodiment 1

[0028] Referring to Figure 1 , a sealing structure for curtain wall panel joints includes an elastic seal 4. The elastic seal 4 is detachably connected to the gap between two adjacent curtain wall panels 3 and is used to seal the gap between two adjacent curtain wall panels 3, so as to achieve the waterproof, heat insulation and sealing effects of the curtain wall panel 3.

[0029] The curtain wall panel 3 is installed on the secondary keel 2. Specifically, curtain wall hanging parts can be used to connect the curtain wall panel 3 and the secondary keel 2. The connection method between the curtain wall panel 3 and the secondary keel 2 is the prior art and will not be elaborated here. The main keel 1 is connected between two adjacent secondary keels 2 to fix the secondary keel 2 and the curtain wall panel 3.

[0030] The elastic seal 4 includes a connected connecting portion 41 and a sealing portion 42. Both the connecting portion 41 and the sealing portion 42 are in contact with the curtain wall panel 3, and the sealing portion 42 is used to seal the gap between two adjacent curtain wall panels 3.

[0031] During the installation process, the operator presses the connecting part 41 of the elastic seal 4 to insert the elastic seal 4 into the gap between two adjacent curtain wall panels 3, so that both the connecting part 41 and the sealing part 42 are in contact with the curtain wall panel 3, realizing the stable connection between the elastic seal 4 and the curtain wall panel 3. At the same time, the sealing part 42 can seal the gap between two adjacent curtain wall panels 3, achieving the waterproof, heat insulation and sealing effects of the curtain wall panel 3.

[0032] When the elastic seal 4 ages during long-term use, the operator pulls the elastic seal 4 to deform the elastic seal 4, and then the elastic seal 4 can be separated from the curtain wall panel 3, and further the elastic seal 4 can be disassembled and replaced, which is beneficial to ensuring the sealing effect of the elastic seal 4 on the gap of the curtain wall panel 3.

[0033] The connecting part 41 includes a support strip 411 and a plurality of limiting strips 412. The limiting strips 412 are connected to both sides of the support strip 411, and the support strip 411 is connected to the sealing part 42. Specifically, there are four limiting strips 412, and they are symmetrically distributed in pairs on both sides of the support strip 411. When connecting the elastic seal 4 with the curtain wall panel 3, the operator presses the plurality of limiting strips 412 of the connecting part 41 on the elastic seal 4 to gradually insert the connecting part 41 into the gap between two adjacent curtain wall panels 3. During this process, the degree of elastic deformation of the support strip 411 is smaller, and the degree of elastic deformation of the limiting strips 412 is larger because there is a certain gap between the limiting strips 412, making it easier to undergo elastic deformation, which is beneficial to improving the smoothness of the connection between the elastic seal 4 and the curtain wall panel 3.

[0034] The limiting strip 412 is integrally connected to the support strip 411, and the support strip 411 is integrally connected to the sealing part 42, making the elastic seal 4 a whole structure, which can reduce the damage of the elastic seal 4 and is beneficial to improving the service life of the elastic seal 4.

[0035] The width of the limiting strip 412 gradually becomes thinner in the direction away from the support strip 411, making the movement margin of the outer end of the limiting strip 412 larger, and making it easier for the limiting strip 412 to deform when passing through the gap between two adjacent curtain wall panels 3.

[0036] The limiting strip 412 is inclined towards the sealing part 42, making the connection process between the elastic seal 4 and the curtain wall panel 3 smoother and the separation process between the elastic seal 4 and the curtain wall panel 3 more difficult, which is beneficial to improving the smoothness of the connection between the elastic seal 4 and the curtain wall panel 3 and making the elastic seal 4 not easily fall off from the gap between two adjacent curtain wall panels 3.

[0037] Multiple said limiting strips 412 are all in contact with the curtain wall panel 3, increasing the contact area between the connecting part 41 and the curtain wall panel 3, thereby improving the connection stability between the elastic seal 4 and the curtain wall panel 3, and making it difficult for the elastic seal 4 to fall off from the gap between two adjacent curtain wall panels 3. Specifically, the support strip 411 and the limiting strip 412 of the elastic seal 4 only extend out of the gap between two adjacent curtain wall panels 3 by a part, so that most of the structure of the elastic seal 4 is located in the gap between two adjacent curtain wall panels 3, further improving the connection stability between the elastic seal 4 and the curtain wall panel 3.

[0038] The cross-section of the sealing part 42 is arranged in an arc structure. When connecting the elastic seal 4 with the curtain wall panel 3, the sealing part 42 contacts the side of the curtain wall panel 3. During the installation process, under the action of two adjacent curtain wall panels 3, the sealing part 42 is extruded and elastically deformed, making the fitting degree between the arc-structured sealing part 42 and the gap of the curtain wall panel 3 closer, which is beneficial to improving the waterproof, heat insulation and sealing effects of the curtain wall panel 3.

[0039] The thickness of the sealing part 42 gradually becomes thinner from the middle to both sides, making the supporting ability of the middle part of the sealing part 42 stronger. The two sides of the sealing part 42 can be more easily deformed under the action of the curtain wall panel 3 and closely fit with the side of the curtain wall panel 3, which is beneficial to improving the sealing ability of the sealing part 42.

[0040] Embodiment 2

[0041] Refer to Figure 2 , the difference between this embodiment and Embodiment 1 is that the support strip 411 of the elastic seal 4 extends out of the gap between two adjacent curtain wall panels 3 by a part, and the end of the support strip 411 far from the sealing part 42 is in contact with the main keel 1, so that the connecting part 41 is in contact with both the curtain wall panel 3 and the main keel 1 at the same time, improving the connection stability between the elastic seal 4 and the curtain wall panel 3.

[0042] All the limiting strips 412 extend out of the gap between two adjacent curtain wall panels 3, and the two limiting strips 412 close to the sealing part 42 are in contact with the side of the curtain wall panel 3 facing the main keel 1, so that while the limiting strips 412 are in contact with the curtain wall panel 3, it is difficult for the elastic seal 4 to fall off from the gap between two adjacent curtain wall panels 3.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
