Description

Technical Field

[0001] This utility model belongs to the field of curtain wall structure technology, and specifically relates to a novel curtain wall vibration damping core. Background Technology

[0002] Currently, on curtain walls, the horizontal beams are fixed to the columns via sleeve connections. In existing technologies, for example... Figure 3 As shown, the existing core sleeve 2' size is generally matched with the cavity of the crossbeam and directly inserted into the crossbeam, but there will be a certain gap between the two to ensure assembly. Furthermore, for example, in strong winds, displacement may occur between the columns and the crossbeams. Since the core sleeve is rigidly connected to the column, friction will occur between the core sleeve and the crossbeam, and friction will also occur between the aluminum materials, producing sound, i.e., noise. Especially for the curtain walls of high-rise buildings, the wind pressure is generally high, and the entire building will sway. This swaying is transmitted to the connection between each column and the crossbeam, generating a significant amount of noise. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of curtain wall shock-absorbing sleeve core, which solves the problem that the existing structure is prone to causing large noise, effectively avoids noise generated by friction between aluminum materials, and at the same time plays the role of shock absorption and buffering.

[0004] According to the technical solution of this utility model, this utility model provides a novel curtain wall vibration damping core. The core is located in the rectangular cavity of the horizontal beam or vertical column of the curtain wall. The outer side dimension of the core is smaller than the inner side dimension of the rectangular cavity. Several elastic strips are distributed on the outer side of the core. The outer side of the core and the four inner sides of the rectangular cavity are all in contact with each other through the elastic strips. Furthermore, there is a buffer gap between the outer side of the core and the four inner sides of the rectangular cavity.

[0005] Furthermore, the core is a profile, and at each of the four corners of the profile's cross-sectional shape, there are two C-shaped elastic strip mounting grooves. The openings of the C-shapes of the elastic strip mounting grooves face the inner wall of the rectangular cavity, and the openings of the two elastic strip mounting grooves are perpendicular to each other. The elastic strips are embedded in the elastic strip mounting grooves. At each corner, the core contacts two adjacent inner walls of the rectangular cavity through the two elastic strips.

[0006] Furthermore, there are notches at the four corners of the cross-sectional shape of the core profile. The notches are located between two adjacent elastic strip mounting grooves, and the positions of the notches correspond to the four edges at the four corners of the rectangular cavity.

[0007] Furthermore, the middle part of the profile cross-section of the sleeve is a sleeve cavity, and at least two C-shaped pin slots are formed at the edge of the sleeve cavity, with matching pins installed in the pin slots.

[0008] Furthermore, there are four pin slots, located at the four corners of the cross-sectional shape of the core profile.

[0009] Furthermore, in the cross-sectional shape of the core profile, at the four edges other than the four corners, there are recessed sidewalls that are concave from the outside to the inside, and the end contours of two adjacent recessed sidewalls together form the pin groove.

[0010] Furthermore, the elastic strip is a cylindrical rubber strip.

[0011] Furthermore, the core is located within the rectangular cavity of the horizontal beam of the curtain wall, and the pin extends out from the end of the horizontal beam; the side of the curtain wall column is provided with a pin hole, and the pin is connected to the pin hole.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This novel curtain wall vibration damping sleeve is suitable for use as a sleeve for horizontal beams, and can also be used as a sleeve for vertical columns. By adding an elastic strip between the sleeve and the rectangular cavity of the installed horizontal beam or vertical column, noise generated by friction between aluminum materials can be effectively avoided, while also playing a role in vibration damping and buffering. The sleeve is equipped with elastic strips on all four sides, so the gap between the sleeve and the rectangular cavity can be increased, making the installation process easier and more convenient. Further preferred design is that one sleeve has four pins to make the force distribution more even. Attached Figure Description

[0019] This utility model provides a novel curtain wall vibration damping core, more specifically a novel structural form for installing a core on a beam / column, mainly aimed at solving the problem that existing structures are prone to causing large noise, effectively avoiding noise generated by friction between aluminum materials, and at the same time playing a role in vibration damping and buffering.

[0020] Please see Figure 1 , Figure 2 This utility model discloses a novel curtain wall vibration damping sleeve core. The sleeve core 1 is located within the rectangular cavity 4 of the curtain wall's horizontal beam 2 or vertical column 3, and is used for connection with other components. The following description uses the case shown in the figure, where the sleeve core 1 is located in the curtain wall's horizontal beam 2, as an example. More specifically, the horizontal beam 2 and vertical column 3 are vertically connected by the sleeve core 1.

[0021] The outer side dimension of the sleeve 1 of this utility model is smaller than the inner side dimension of the rectangular cavity 4. Several elastic strips 5 are distributed on the outer side of the sleeve 1. The outer side of the sleeve 1 and the four inner sides of the rectangular cavity 4 are all in contact with each other through the elastic strips 5, and there is a buffer gap 6 between the outer side of the sleeve 1 and the four inner sides of the rectangular cavity 4. In other words, the sleeve 1 is suspended in the middle of the rectangular cavity 4 by the elastic strips 5 around it, and does not directly contact the inner wall of the rectangular cavity of the beam 2 (or column 3) where it is located, and does not adopt the rigid connection between the beam and the sleeve in the existing solution. Therefore, due to the presence of the elastic strip 5 and the buffer gap 6, the crossbeam 2 (or column 3) and the sleeve 1 will not collide or rub against each other (or at least will not collide or rub against each other violently / frequently). Furthermore, when the sleeve 1 and the rectangular cavity of the crossbeam 2 (or column 3) undergo a certain relative displacement, it is not a direct friction between the aluminum materials. Therefore, compared with the prior art, noise problems can be effectively avoided (or reduced). At the same time, the presence of the buffer gap 6 also makes it easier for the sleeve 1 to be installed into the rectangular cavity 4.

[0022] More specifically, the core 1 is a profile (aluminum alloy profile). At each of the four corners of the profile's cross-sectional shape, there are two C-shaped elastic strip mounting grooves. The openings of the C-shapes of the elastic strip mounting grooves face the inner wall of the rectangular cavity 4, and the openings of the two elastic strip mounting grooves are perpendicular to each other. The elastic strips 5 are embedded in the elastic strip mounting grooves, with a portion of the outer side of the elastic strips 5 protruding outside the elastic strip mounting grooves. Thus, at each corner, the core 1 contacts two adjacent inner walls of the rectangular cavity 4 through the two elastic strips 5, thereby forming a buffer gap 6 between the core 1 profile and the inner wall of the rectangular cavity 4 through the support of the elastic strips 5.

[0023] Preferably, the elastic strip 5 is a cylindrical rubber strip with strong radial elasticity, especially when it is embedded in a C-shaped elastic strip mounting groove of a suitable size. The elasticity and size of the elastic strip 5, as well as the size design of the buffer gap 6, are preferably such that even when a relatively large external force is applied to one side, the core 1 profile cannot be tightly fitted to the rectangular cavity 4; and after the core 1 moves to one side relative to the rectangular cavity 4, the elastic strip 5 on the other side will not completely separate from the rectangular cavity 4; especially, under the natural service of the curtain wall structure, it is almost impossible for external force to cause the core 1 to displace relative to the rectangular cavity 4 only in the orthogonal front-back or up-down direction. Therefore, with two elastic strips 5 at both ends on each side of this scheme, it can be ensured that at least one elastic strip 5 is in contact with the rectangular cavity 4, that is, the core 1 is always constrained on all four sides inside the rectangular cavity 4; in addition, the surface of the elastic strip 5 (rubber strip) has a larger coefficient of friction than aluminum, thus effectively ensuring the shock absorption and buffering effect between the core 1 profile and the rectangular cavity 4; and the smaller displacement in the left-right direction (such as the direction of the beam length) can also be buffered by the elastic strip 5 in addition to avoiding direct friction between aluminum materials.

[0024] Furthermore, there are notches 7 at the four corners of the cross-sectional shape of the core 1 profile. The notches 7 are located between two adjacent elastic strip mounting grooves. The position of the notches 7 corresponds to the four edges of the four corners of the rectangular cavity 4. The notches 7 form a larger buffer space, making it less prone to friction.

[0025] The core 1 is preferably a profile with a cavity, specifically, the central part of the cross-sectional shape of the core 1 profile is the core cavity 8, which helps to make the core 1 lighter. At least two C-shaped pin slots are formed at the edge of the core cavity 8, and pins 9 are installed in matching pin slots, so that they can be connected and positioned with other components of the curtain wall (such as columns) through the pins 9. It is conceivable that too few pin slots will result in unstable positioning, while too many will lead to redundancy and complex structure and installation; the pin slots can be located at the edge or corner of the core 1. Preferably, there are four pin slots, located near the four corners of the cross-sectional shape of the core 1 profile and near the elastic strip 5, so that the connection and positioning effect of the core 1 on other components of the curtain wall (such as columns) is better and the force is more even. Furthermore, in the cross-sectional shape of the core 1 profile, there are recessed sidewalls 10 at the four edges except for the four corners, which are recessed from the outside to the inside. The end contours of two adjacent sidewalls 10 together form a pin groove. The C-shaped elastic strip mounting groove is located outside the two ends of the sidewalls 10. This structure is simpler and more resilient.

[0026] In application, the core 1 is located within the rectangular cavity 4 of the horizontal beam 2 of the curtain wall. The pin 9 extends from the end of the horizontal beam 2. Pin holes 11 are provided on the side of the curtain wall's columns 3. The pins 9 and pin holes 11 are connected one-to-one, thus achieving a vertical connection between the horizontal beam 2 and the columns 3. And, as... Figure 1 As shown, there is a connecting beam outside the rectangular cavity 4 on the beam 2 (and the column 3), and an outer profile is installed at the end of the connecting beam by means of, for example, screws. Curtain wall glass is installed between the outer profile and the beam 2 (and the column 3).

[0027] Please see Figure 3 Alternatively, existing technology patents, such as the Chinese utility model patent with authorization announcement number CN208633338U, involve the existing core sleeve 1' being directly inserted into the rectangular cavity 4. Ideally, the two should be the same size, but this is difficult to achieve in practice. If the sizes are the same, the existing core sleeve 1' will be unable or difficult to install into the rectangular cavity 4. Furthermore, if the existing core sleeve 1' is fixedly connected to the rectangular cavity 4, it will prevent them from generating a certain amount of displacement under external force or thermal deformation, which will be detrimental to the stability of the overall structure. Therefore, in reality, there will be a small gap between the existing core sleeve 1' and the rectangular cavity 4, and this gap will lead to the aforementioned noise problem. Alternatively, more precise dimensional processing methods or more complex structures / installation methods may be used to avoid noise, but if the entire curtain wall adopts complex processes, it will lead to a significant increase in time and economic costs, making it difficult to apply in practice. The solution of this utility model can solve the aforementioned noise problem with relatively lower cost and relatively more convenient installation operation.

[0028] In summary, the novel curtain wall vibration damping sleeve of this utility model can effectively avoid noise generated by friction between aluminum materials by adding elastic strips between the sleeve and the rectangular cavity of the installed beam or column, and at the same time play a role in vibration damping and buffering. Since elastic strips are installed on all four sides of the sleeve, the gap between the sleeve and the rectangular cavity can be increased, making the installation process easier and more convenient.
