Furthermore, for example, in the case of strong winds, displacement may occur between the column and the beam. The sleeve core and the column are hard-connected, and there will be movement friction between the sleeve core and the beam. The friction between the aluminum materials will produce sound, that is, noise. Especially for the curtain wall of a high-rise building, the wind pressure is generally large, and the whole building will swing. This swing is transmitted to the connection between each column and the beam, and the noise generated will be much louder. Summary of the invention

[0017] The present invention provides a novel curtain wall shock-absorbing sleeve core, more specifically a novel structure of a beam / column assembly sleeve core, which is mainly intended to solve the problem that the existing structure easily causes high noise, effectively avoid noise generated by friction between aluminum materials, and at the same time play a role of shock absorption and buffering.

[0018] See also Figure 1 , Figure 2The present invention discloses a novel curtain wall shock absorbing sleeve core, wherein the sleeve core 1 is located in a rectangular cavity 4 of a beam 2 or a column 3 of the curtain wall, and is used to connect with other components. The following is a specific description of the case where the sleeve core 1 is located in the beam 2 of the curtain wall as shown in the figure, and more specifically, the beam 2 is vertically connected to the column 3 through the sleeve core 1.

[0019] The outer side dimension of the sleeve core 1 of the present invention is smaller than the inner side dimension of the rectangular cavity 4, and a plurality of elastic strips 5 are distributed on the outer side of the sleeve core 1. The outer side of the sleeve core 1 and the four inner sides of the rectangular cavity 4 are in contact with each other through the elastic strips 5, and there are buffer gaps 6 between the outer side of the sleeve core 1 and the four inner sides of the rectangular cavity 4; in other words, the sleeve core 1 is suspended in the middle of the rectangular cavity 4 through the elastic strips 5 on all sides, does not directly contact the inner wall of the rectangular cavity of the beam 2 (or column 3), and does not adopt the hard connection between the beam and the sleeve core in the existing solution. Therefore, due to the presence of the elastic strip 5 and the buffer gap 6, in windy weather or when there are other external disturbances, there will be no collision or friction between the crossbeam 2 (or column 3) and the sleeve core 1 therein (or at least no violent / high-frequency collision or friction), and when the sleeve core 1 and the rectangular cavity of the crossbeam 2 (or column 3) undergo a certain relative displacement, there is no direct friction between the aluminum materials. Therefore, compared with the prior art, the noise problem can be effectively avoided (or alleviated); at the same time, the presence of the buffer gap 6 also makes it easier for the sleeve core 1 to be installed into the rectangular cavity 4.

[0020] More specifically, the sleeve core 1 is a profile (aluminum alloy profile), and two C-shaped elastic strip mounting grooves are provided at each of the four corners of the profile cross-section. The C-shaped opening of the elastic strip mounting groove faces the inner wall of the rectangular cavity 4, and the C-shaped opening directions of the two elastic strip mounting grooves are perpendicular to each other; the elastic strip 5 is embedded in the elastic strip mounting groove, and a part of the elastic strip 5 on the outer side is exposed outside the elastic strip mounting groove; thus, at each corner, the sleeve core 1 contacts two adjacent inner walls of the rectangular cavity 4 through the two elastic strips 5, and, in this way, a buffer gap 6 is formed between the sleeve core 1 profile and the inner wall of the rectangular cavity 4 through the support of the elastic strip 5.

[0021] Preferably, the elastic strip 5 is a cylindrical rubber strip having strong elasticity in the radial direction, especially when embedded in a C-shaped elastic strip installation groove with matching size. The elasticity, size and size of the elastic strip 5 and 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 with 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 be completely separated from the rectangular cavity 4; in particular, when the curtain wall structure is in natural service, it is almost impossible for external force to cause the core 1 to be displaced only in the orthogonal front-back or up-down directions relative to the rectangular cavity 4. Therefore, in the case of two elastic strips 5 at both ends of each side of the present solution, 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 in a state of being constrained on all four sides in the rectangular cavity 4; in addition, the surface of the elastic strip 5 (rubber strip) will have a larger friction coefficient than that of aluminum, so it can effectively ensure the shock absorption and buffering effect between the core 1 profile and the rectangular cavity 4; and in addition to avoiding direct friction between aluminum materials, small displacements in the left and right directions (such as the length direction of the beam) can also be buffered by the elastic strip 5.

[0022] Furthermore, there are notches 7 at the four corners of the cross-sectional shape of the sleeve core 1 profile, and the notches 7 are located between two adjacent elastic strip mounting grooves. The positions of the notches 7 correspond to the four edges at the four corners of the rectangular cavity 4; the notches 7 are equivalent to forming a larger buffer space, so friction is less likely to occur.

[0023] The core 1 is preferably a profile with a cavity. Specifically, the middle part of the profile cross-section of the core 1 is the core cavity 8, which helps to make the core 1 lighter. At least two C-shaped latch grooves are formed at the edge of the core cavity 8, and latches 9 are matched and installed in the latch grooves, so that the core 1 can be connected and positioned with other components of the curtain wall (such as columns) through the latches 9. It can be imagined that too few latch grooves will lead to unstable positioning, and too many will lead to redundancy and complex structure and installation; the latch grooves can be optionally located at the edges or corners of the core 1. Preferably, there are four latch grooves, which are located near the four corners of the cross-section of the core 1 profile and close to 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 uniform. Furthermore, in the cross-sectional shape of the sleeve core 1 profile, the four edges except the four corners are all groove side walls 10 that are recessed from the outside to the inside, and the end contours of the two adjacent groove side walls 10 jointly form a pin groove, and the C-shaped elastic strip installation groove is located outside the two ends of the groove side wall 10, so that the structure is simpler and more resilient.

[0024] When this solution is applied, the core 1 is located in the rectangular cavity 4 of the beam 2 of the curtain wall, the latch 9 extends out of the end of the beam 2, and the side of the column 3 of the curtain wall is provided with a latch hole 11, and the latch 9 is connected to the latch hole 11 in a one-to-one correspondence, so as to realize the vertical connection between the beam 2 and the column 3. And, if Figure 1 As shown, a connecting beam is provided outside the rectangular cavity 4 on the cross beam 2 (and the column 3 ), an outer profile is installed at the end of the connecting beam by, for example, screws, and curtain wall glass is arranged between the outer profile and the cross beam 2 (and the column 3 ).

[0025] See also Figure 3 , or the prior art patents such as the Chinese utility model patent with the authorization announcement number CN208633338U, wherein the existing sleeve core 1' is directly inserted into the rectangular cavity 4. Ideally, the two have the same size, but it is difficult to achieve in practice, because if the size is the same, the existing sleeve core 1' will not be able to / difficult to install into the rectangular cavity 4, and if the existing sleeve core 1' and the rectangular cavity 4 are fixedly connected, it will also cause the two to be unable to produce a certain amount of displacement under external force or thermal deformation, which will be detrimental to the stability of the overall structure; therefore, in fact, there will be a small gap between the existing sleeve core 1' and the rectangular cavity 4, and this gap will cause the aforementioned noise problem; or it may be possible to avoid noise by using a more sophisticated size processing method or a more complex structure / installation method, but if the curtain wall adopts a complex process as a whole, it will lead to a significant increase in time and economic costs, making it difficult to apply in practice. The solution of the present invention can solve the aforementioned noise problem at a relatively lower cost and with a relatively more convenient installation operation.

[0026] In summary, the novel curtain wall shock-absorbing sleeve core of the present invention can effectively avoid the noise generated by friction between aluminum materials by adding elastic strips between the sleeve core and the rectangular cavity of the installed beam or column, and at the same time play a role of shock absorption and buffering; elastic strips are installed on the four sides of the sleeve core, so the gap between the sleeve core and the rectangular cavity can be increased, making the installation process easier and more convenient.
