[0002] Curtain wall refers to a non-load-bearing exterior wall system installed on the exterior structure of a building. Curtain wall usually consists of multiple profiles and a supporting structure that firmly supports the profiles on the exterior wall of the building. Waterproofing is a crucial design in curtain wall design, which needs to effectively prevent moisture from penetrating into the building to protect the integrity and stability of the wall structure.

[0003] In traditional curtain wall, profiles are usually installed on the exterior wall of the building by gluing, and there are usually gaps between multiple profiles. To prevent rainwater from seeping in, the gaps need to be filled with glue, which results in a lot of gluing work and a long construction period. Therefore, it is necessary to develop a profile that has waterproof properties and can greatly reduce the amount of on-site gluing work, which is conducive to shortening the construction period. Utility Model Content

[0004] One purpose of the utility model is to solve the deficiencies in the prior art and to provide a profile having waterproof properties and capable of greatly reducing the amount of on-site gluing work, thereby facilitating shortening the construction period.

[0011] In an exemplary embodiment, a guide groove is provided on the connecting portion, and a sealing strip is mounted on the guide groove; the sealing strip abuts against the inner wall of the receiving groove on the adjacent profile.

[0012] In an exemplary embodiment, a bending portion is protruded from the installation step in a direction away from the building exterior wall, and the bending portion is close to the extension portion and extends in the same direction as the extension portion.

[0013] In an exemplary embodiment, a cavity for filling with sealant is provided on the installation step, and the fastener passes through the cavity and is connected to the exterior wall of the building.

[0014] In an exemplary embodiment, a transition surface is provided between the installation step and the front surface of the plate body, and the transition surface is inclined downward from the installation step and extends to the front surface of the plate body.

[0015] In an exemplary embodiment, the side wall of the extension portion facing away from the building exterior wall is in the same plane as the front surface of the plate body.

[0030] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0031] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] The present invention provides a curtain wall profile and curtain wall, which has waterproof performance and can greatly reduce the amount of on-site glue application work, which is conducive to shortening the construction period. The specific scheme is described through the following embodiments.

[0034] See also Figure 1 and Figure 2 The curtain wall of this embodiment includes a plurality of profiles arranged in parallel. The plurality of profiles are spliced ​​and installed on the building exterior wall 5 to form the curtain wall.

[0035] It should be noted that the building exterior wall 5 can be the exterior wall of a traditional immovable building or the exterior wall of a movable building. For example, the profile can be used on the exterior wall of a modular building. The specific configuration can be based on actual needs. This embodiment takes the profile installed on the exterior wall of a modular building as an example.

[0036] It should be noted that in actual use, a connection structure (not shown) is also provided to firmly support the profile on the building outer wall 5. The connection structure is provided between the profile and the building outer wall 5, which means that there is a gap 7 between the profile and the building outer wall 5.

[0037] In addition, the profiles can be spliced ​​up and down, or left and right, and the specific configuration can be made according to actual needs, and no limitation is made here. This embodiment is described by taking the splicing of multiple profiles up and down as an example.

[0038] See also Figure 4 Combined with Figure 3 ,in Figure 4 It is a cross-sectional view of a profile along a direction perpendicular to the extension direction of the profile.

[0039] The profile of this embodiment includes a plate body 1 , a mounting step 2 and a connecting end 3 .

[0040] The board body 1 includes a front side 11 and a back side 12. The front side 11 is opposite to the back side 12. The front side 11 is the side of the board body 1 away from the building outer wall 5. That is, the back side 12 is the side of the board body 1 close to the building outer wall 5.

[0041] The mounting step 2 is provided at one end of the plate body 1, and the fastener 4 passes through the mounting step 2 and is connected to the building exterior wall 5, so as to fasten and install the profile on the building exterior wall 5. Compared with the traditional profile that is bonded to the building exterior wall 5 by bonding, the profile in the utility model greatly reduces the amount of gluing work, improves the work efficiency of profile installation, and is conducive to shortening the construction period.

[0042] Further, see Figure 5 A positioning groove 21 is recessed on the outer side wall of the installation step 2 to facilitate the installation of the fastener 4 and prevent the fastener 4 from slipping during installation.

[0043] In some examples, a cavity 22 is provided on the installation step 2, and the fastener 4 passes through the cavity 22 and is connected to the building exterior wall 5. The cavity 22 can prevent rainwater from entering the gap 7 between the profile and the building exterior wall 5 through the fastener 4 to damage the connection structure, thereby affecting the stability of the entire curtain wall; and can prevent rainwater from entering the building exterior wall 5 and causing damage to the building exterior wall 5. Specifically, even if rainwater flows along the fastener 4, when it flows to the cavity 22, under the action of gravity, the rainwater drips into the cavity 22 and no longer flows along the extension direction of the fastener 4.

[0044] The cavity 22 may be filled with sealant (not shown) to further prevent rainwater from entering the building exterior wall 5 or the gap 7 between the profile and the building exterior wall 5 along the fastener 4 .

[0045] In some embodiments of the present application, a sealing layer (not shown) is provided at the connection between the installation step 2 and the fastener 4 to prevent rainwater from entering the interior of the curtain wall through the connection between the installation step 2 and the fastener 4.

[0046] Continue to see Figure 3 The curtain wall also includes a pad 6, which is arranged between the profile and the building exterior wall 5. The pad 6 has the function of buffering and waterproofing. Specifically, the pad 6 is arranged between the installation step 2 and the building exterior wall 5. That is, after the fastener 4 is passed through the installation step 2, the pad 6 needs to be passed through and then connected to the building exterior wall 5. The material of the pad 6 can be substantially soft, which is conducive to reducing the damage to the building exterior wall 5 after the external force impacts the curtain wall, and can also improve the wind pressure resistance and overall stability of the curtain wall; in addition, the pad 6 fits tightly with the installation step 2, which can also effectively prevent water from flowing along the extension direction of the fastener 4 to the connecting structure, or flowing to the building exterior wall 5.

[0047] See also Figure 3 and Figure 4, the connecting end 3 is provided at the other end of the plate body 1, and the connecting end 3 can fix the adjacent profiles. Specifically, the mounting step 2 is provided with a convex connecting portion 23. The connecting end 3 is provided with a concave receiving groove 31. The receiving groove 31 is used to receive the connecting portion 23 of the adjacent profile. That is, when two adjacent profiles are spliced ​​up and down, the receiving groove 31 of the upper profile receives the connecting portion 23 of the lower profile. It can be understood that the receiving groove 31 cooperates with the connecting portion 23, so that the connecting portion 23 of the mounting step 2 on the lower profile is inserted into the receiving groove 31 on the connecting end 3 on the upper profile, and this installation method is simple and quick.

[0048] For the convenience of description, the upper profile is referred to as the first profile, and the lower profile is referred to as the second profile. Figure 6 The receiving groove 31 of the first profile includes a first wall 311 close to the building outer wall 5, a second wall 312 away from the building outer wall 5, and a bottom wall 313 located between the first wall 311 and the second wall 312. The first wall 311, the second wall 312 and the bottom wall 313 are surrounded to form the receiving groove 31.

[0049] Combination Figure 3 When the first profile is spliced ​​with the second profile, the connection portion 23 of the second profile is located between the first wall 311 and the second wall 312 of the first profile. The end surface of the first wall 311 abuts against the end surface of the installation step 2. In the direction perpendicular to the building exterior wall 5, the connection portion 23 on the second profile can resist the first wall 311 on the first profile from moving in a direction away from the building exterior wall 5. In other words, the connection portion 23 on the second profile can fix the connection end 3 on the first profile, further improving the stability of the profile, which is beneficial to enhancing the structural strength of the curtain wall formed by splicing multiple profiles.

[0050] In some embodiments, a guide groove 231 is provided on the connecting portion 23, and a sealing strip 232 is installed on the guide groove 231. When the first profile is spliced ​​with the second profile, the sealing strip 232 on the second profile is tightly against the inner wall of the receiving groove 31 on the first profile. This is equivalent to the inner wall of the receiving groove 31 on the first profile squeezing the sealing strip 232 on the second profile protruding from one side of the guide groove 231, thereby blocking the splicing seam generated when the upper and lower profiles are spliced, and further preventing water or water vapor from penetrating into the interior of the curtain wall from the splicing of adjacent profiles. Here, the interior of the curtain wall is from the building exterior wall 5 to the back side 12 of the plate body 1.

[0051] See Figure 5, the notch of the guide groove 231 can be oriented toward the front side 11 of the plate body 1, that is, away from the exterior wall 5 of the building, and at this time, the sealing strip 232 on the second profile is tightly against the second wall 312 of the receiving groove 31 on the first profile. In other embodiments, the notch of the guide groove 231 can be oriented toward the back side 12 of the plate body 1, and at this time, the sealing strip 232 on the second profile is tightly against the first wall 311 of the receiving groove 31 on the first profile. Alternatively, the notch of the guide groove 231 can be oriented toward the bottom of the receiving groove 31, and at this time, the sealing strip 232 on the second profile is tightly against the bottom wall 313 of the receiving groove 31 on the first profile. The specific configuration can be based on actual needs and is not limited here.

[0052] Continue reading Figure 3 and Figure 6 , an extension portion 32 is provided on the side of the connection end 3 away from the building exterior wall 5, and the extension portion 32 at least partially covers the installation step 2 of the adjacent profile. That is, the extension portion 32 of the connection end 3 on the first profile at least partially covers the installation step 2 on the second profile. It can be understood that the extension portion 32 covers the joint seam when the first profile and the second profile are spliced, so that rainwater can smoothly slide down to the second profile along the extension direction of the extension portion 32, effectively preventing rainwater from penetrating from the joint seam where the adjacent first profile and the second profile are spliced.

[0053] Furthermore, the extension portion 32 at least partially covers the fastener 4 , thereby preventing the fastener 4 from directly contacting rainwater, thereby effectively preventing the fastener 4 from being corroded by rainwater.

[0054] In some embodiments, the side wall of the extension portion 32 facing away from the building exterior wall 5 is in the same plane as the front surface 11 of the panel body 1, so as to help maintain the overall flatness of the curtain wall.

[0055] See also Figure 5 A transition surface 13 is provided between the mounting step 2 and the front surface 11 of the plate body 1. The transition surface 13 is inclined downward from the mounting step 2 and extends to the front surface 1 of the plate body 1. Therefore, even if water accidentally enters from the gap between the extension portion 32 on the first profile and the plate body 1 of the second profile, it will be guided to flow out to the front surface 11 of the plate body 1 under the action of the transition surface 13.

[0056] The installation step 2 is provided with a bent portion 24 protruding in the direction away from the building exterior wall 5. The bent portion 24 is close to the extension portion 32 and extends in the same direction as the extension portion 32. The bent portion 24 can also block a portion of water vapor. In addition, the bent portion 24 also has a supporting function. Specifically, when the upper and lower profiles are spliced, the extension portion 32 covers the bent portion 24, and the bent portion 24 has a supporting function for the extension portion 32, which can prevent the extension portion 32 from breaking and enhance the structural strength of the curtain wall.

[0057] See also Figure 6, the ends on both sides of the connection end 3 are each provided with a convex rib 33 facing the inside of the profile to further block the entry of rainwater. Specifically, the protrusion 33 includes a first convex rib 331 and a second convex rib 332, and the first convex rib 331 and the second convex rib are respectively provided on both sides of the connection end 3. The first convex rib 331 is provided on the side wall of the connection end 3 located on the back side 12, that is, the first convex rib 331 is provided on the first wall 311 of the receiving groove 31, and the first convex rib 331 faces the front side 11 of the plate body 1. The second convex rib 332 is provided at the end of the extension portion 32, and the second convex rib 332 faces the back side 12 of the plate body 1.

[0058] In this embodiment, the profile is in the shape of a strip, that is, a rectangular shape. In some other embodiments, the profile may also be in the shape of a square, a triangle, etc. Taking the profile as a square as an example, the upper end of the square profile is provided with a mounting step, and the lower end is a connecting end, so that multiple square profiles can be spliced. The left and right ends of the square profile may also be provided with a mounting step at one end, and the other end is a connecting end.

[0059] In some examples of the present application, the profile is an aluminum profile, which has the characteristics of light weight, high strength, strong corrosion resistance, and convenient maintenance.

[0060] It can be seen from the above technical solution that the profile provided in this embodiment has the following advantages and beneficial implementation effects.

[0061] Multiple profiles can be spliced ​​together in a plug-in manner, so that they can be quickly installed, improve work efficiency, and shorten the construction period. The profile has good waterproof ability and is provided with multiple structures to prevent rainwater penetration, including but not limited to the bending part and cavity 22 on the installation step 2, the sealing strip 232 on the connection part 23, the convex rib 33 on the connection end 3, the transition surface 13, etc. The profile of this embodiment does not need to fill the gap between adjacent profiles with glue like in traditional profiles, thereby greatly reducing the amount of glue application work, which is further conducive to shortening the construction period.

[0062] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0063] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
