Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a sealing strip for curtain walls. Background Technology

[0002] As an important component of the exterior envelope of modern buildings, the sealing performance of curtain walls directly affects the airtightness, watertightness, and sound and heat insulation of buildings. Traditional curtain wall sealing strips mostly use single-structure rubber or elastomer materials, which achieve contact sealing with the profiles or glass through extrusion deformation. However, such sealing strips have the following shortcomings: (1) the single-cavity structure is prone to plastic deformation after long-term pressure, resulting in sealing failure; (2) it has poor adaptability to profile dimensional tolerances and installation deviations, and is prone to local sealing failure. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a sealing strip for curtain walls.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sealing strip for curtain walls includes a strip body, a connecting part for inserting into a profile is provided on one side of the upper end of the strip body, and a sealing part is provided on the lower end of the strip body opposite to the connecting part. The sealing part includes an outwardly protruding protrusion, a plurality of cavities are provided in the protrusion, and a first sealing arc strip extending outward is provided on the protrusion.

[0006] In some embodiments, the first sealing arc-shaped strip is provided in multiple intervals.

[0007] In some embodiments, a second sealing arc-shaped strip is further provided on the main body of the adhesive strip and on the upper side of the sealing portion.

[0008] In some embodiments, the connecting portion includes a plug-in portion, and hook portions are provided on both sides of the plug-in portion.

[0009] In some embodiments, the insertion portion is provided with a cavity.

[0010] In some embodiments, a support portion is provided on the adhesive strip body and on the side opposite to the sealing portion.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The protrusions on the sealing part have multiple independent cavities that form an elastic support. The stress is effectively dispersed through the coordinated deformation between the cavities. While ensuring compression rebound, the sealing contact pressure is evenly distributed. At the same time, the cavity structure can absorb vibration energy and reduce noise transmission. The first sealing arc strip provides a contact seal to prevent water and air penetration.

[0014] Figure 2 This is a schematic diagram of the structure of this utility model after installation. Detailed Implementation

[0015] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0016] like Figures 1-2 The sealing strip for curtain walls shown includes a strip body 1. A connecting part 2 for inserting into a profile 10 is provided on one side of the upper end of the strip body 1. A sealing part 3 is provided on the lower end of the strip body 1 opposite to the connecting part 2. The sealing part 3 includes an outwardly protruding protrusion 4. A plurality of cavities 5 are provided in the protrusion 4. A first sealing arc strip 6 extending outward is also provided on the protrusion 4.

[0017] According to the above structure, the multiple independent cavities 5 provided in the protrusion 4 on the sealing part 3 form an elastic support. The stress is effectively dispersed through the coordinated deformation between the cavities 5. While ensuring compression rebound, the sealing contact pressure distribution is made uniform. At the same time, the structure of the cavity 5 can absorb vibration energy and reduce noise transmission. The first sealing arc strip 6 provides a contact seal to prevent water and air penetration.

[0018] Furthermore, multiple first sealing arc-shaped strips 6 are spaced apart, and multiple first sealing arc-shaped strips 6 form a gradient seal to prevent leakage caused by the failure of a single seal. The spacing design allows each first sealing arc-shaped strip 6 to deform independently, compensating for the displacement deviation of the curtain wall.

[0019] In this invention, a second sealing arc-shaped strip 31 is also provided on the main body 1 of the adhesive strip and on the upper side of the sealing part 3 to further improve the sealing performance.

[0020] In this utility model, the connecting part 2 includes a plug-in part 41, and hook parts 42 are provided on both sides of the plug-in part 41; the plug-in part 41 is guided into the insertion, and the hooks are elastically deformed and then reset and locked; the hook parts 42 engage with the inner wall of the profile groove to prevent the rubber strip from coming out.

[0021] Furthermore, a cavity 51 is provided inside the plug-in part 41. The cavity 51 allows the plug-in part 41 to be deformed under pressure, adapting to the dimensional tolerances of the profile. At the same time, the cavity 51 reduces the amount of material used and lowers the cost.

[0022] In this utility model, a support part 61 is provided on the main body 1 of the adhesive strip and on the side opposite to the sealing part 3. The support part 61 abuts against the curtain wall frame to prevent the adhesive strip from twisting and deforming, thereby the support part 61 bears the external load and reduces the pressure fatigue of the sealing part.

[0023] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
