Description

Technical Field

[0001] This application relates to the field of curtain wall structures, and particularly to a high-displacement seismic curtain wall. Background Art

[0002] A curtain wall structure generally includes curtain wall panels and connectors. The curtain wall panels are installed on a building through the connectors. Common buildings include office buildings, automobile 4S stores, etc. Among them, in order to enhance the display effect of automobiles in the exhibition hall of an automobile 4S store, a larger area of glass curtain wall is adopted.

[0003] When an earthquake occurs, the vibration on the building is transmitted to the connectors and the curtain wall panels. In areas with frequent earthquakes, it is easy to cause displacement collisions between the curtain wall panels, resulting in structural damage to the curtain wall panels. Summary of the Invention

[0004] In order to improve the seismic effect, this application provides a high-displacement seismic curtain wall.

[0005] A high-displacement seismic curtain wall provided by this application adopts the following technical solutions:

[0006] A high-displacement seismic curtain wall includes curtain wall panels, a mounting frame fixed to a building, and an elastic connection assembly for connecting the curtain wall panels and the mounting frame. There is an activity gap between two adjacent curtain wall panels, and an elastic waterproof structure is provided between two adjacent curtain wall panels; the elastic connection assembly includes a connecting rod, a sleeve, and a first ball head seat. The first ball head seat is fixedly connected to the mounting frame relatively. The sleeve is fixedly connected to the first ball head seat. The axis of the sleeve is horizontally perpendicular to the surface of the mounting frame. A second ball head seat is installed on the back of the curtain wall panel. A second ball head is fixed at one end of the connecting rod, and a first ball head is fixed in the middle of the connecting rod. The connecting rod passes through the sleeve. The first ball head and the first ball head seat are connected by a first damping pad in a mating manner, and the second ball head and the second ball head seat are connected by a second damping pad in a mating manner; a conical inner cavity is provided in the sleeve, and the inner diameter of the conical inner cavity gradually increases in the direction away from the first ball head seat. A plurality of circumferentially spaced limiting springs are provided in the conical inner cavity, and the limiting springs are used to force the connecting rod and the sleeve to maintain a coaxial state.

[0007] By adopting the above technical solutions, when the curtain wall panel is displaced due to the vibration force from wind pressure or an earthquake, through the connecting rod with double ball head connections provided, the vibration force will be converted into a swing of the connecting rod around the center of the ball formed by the cooperation of the first ball head and the first ball head seat, that is, the original vibrating displacement is amplified into a high displacement through the swing of the connecting rod. The high displacement of the connecting rod will compress the limiting springs to convert the vibration force into the elastic potential energy of the limiting springs and the frictional heat energy of the first damping pad and the second damping pad, thereby extremely effectively reducing the vibration force and greatly improving the seismic effect.

[0008] Moreover, the provision of the movement gap and the elastic waterproof structure can reduce the displacement collision between adjacent curtain wall panels, thereby reducing the structural damage to the curtain wall panels.

[0009] Optionally, two sleeves are provided, and the two sleeves are symmetrically arranged with the first ball head seat as the center.

[0010] By adopting the above technical solution, by providing two sleeves to respectively correspond to the two swinging positions of the connecting rod, the elastic limiting effect on the connecting rod can be improved, so that the seismic force can be more completely and quickly converted into the elastic potential energy of the limiting spring, further improving the buffering effect.

[0011] Optionally, a mounting seat is installed on the back surface of the curtain wall panel. The second ball head seat is a split structure, and the second ball head seat is bolted to the mounting seat; a connecting ring is fixed at the opening of the sleeve away from the curtain wall panel, and the connecting ring is bolted to the mounting frame.

[0012] By adopting the above technical solution, by providing the split structure of the second ball head seat, the installation between the second ball head and the second ball head seat can be simplified, and by providing the connecting ring, the installation strength of the sleeve can be further improved.

[0013] Optionally, a damping arc piece is fixed at the end of the connecting rod away from the second ball head. A spherical groove is formed on the surface of the mounting frame corresponding to the damping arc piece. The center of curvature of the spherical groove is located at the center of the circle of the first ball head, and the groove surface of the spherical groove is covered with a third damping pad, and the damping arc piece abuts against the third damping pad.

[0014] By adopting the above technical solution, when the curtain wall panel vibrates, the curtain wall panel forces the connecting rod to swing around the center of the ball formed by the cooperation of the first ball head and the first ball head seat. By using the swing of the connecting rod to amplify the relative displacement stroke between the damping arc piece and the third damping pad, and generating heat through the friction between the damping arc piece and the third damping pad, the seismic force received by the curtain wall panel can be greatly dissipated, thereby further improving the seismic resistance effect.

[0015] Optionally, the sleeve is threadedly connected with a preloading bolt corresponding to the limiting spring. The preloading bolt is coaxially arranged with the limiting spring, and the end of the preloading bolt abuts against the end of the limiting spring away from the connecting rod.

[0016] By adopting the above technical solution and setting a pre-stressing bolt, the pre-elastic force of the limit spring can be adjusted to adapt to different building environments. For example, the elastic potential energy of the limit spring can be increased to increase the rigidity of the limit spring to increase its buffering capacity for high-frequency vibrations; the elastic potential energy of the limit spring can be reduced to increase the buffering effect of the limit spring to increase its buffering capacity for low-frequency vibrations.

[0017] Optionally, the edge of the curtain wall panel is set to be an arc edge, and the elastic waterproof structure includes two first rubber strips, which are arranged in a one-to-one correspondence with the curtain wall panels, and a cavity is provided in the first rubber strip, and a plurality of elastic supporting ribs are integrally formed in the inner cavity of the first rubber strip; an arc-shaped edging is integrally formed on one side of the first rubber strip, and the edging wraps the arc edge of the curtain wall panel, and the adjacent sides of the two first rubber strips are connected.

[0018] By adopting the above technical solution, by setting the first rubber strip and the edging, firstly, the movable gap can be waterproofed; secondly, when the curtain wall panel vibrates and has a high displacement, the edging can cover the arc edge as much as possible to improve the waterproof performance; thirdly, when the curtain wall panel vibrates and has a high displacement, the movable gap is reduced, the first rubber strip is squeezed, and the deformation force of the first rubber strip is converted by the vibration force of the curtain wall panel, that is, it plays a role in buffering the vibration force to improve the seismic effect; fourthly, the elastic support ribs can increase the elastic force of the first rubber strip to improve the buffering effect.

[0019] Optionally, the elastic waterproof structure also includes a second rubber strip, which is horizontally perpendicular to the surface of the mounting frame, and there is an angle of 120° between the first rubber strip and the second rubber strip; one side of the second rubber strip is connected to the side edges of the two first rubber strips, and the other side of the second rubber strip is connected to the mounting frame via a first support rod.

[0020] By adopting the above technical solution, when the curtain wall panel vibrates and has a high displacement, resulting in a reduction in the active gap, that is, when the curtain wall panel has a vertical reciprocating displacement, the vibration force will be transmitted to the second rubber strip through the inclined first rubber strip, and then act vertically on the mounting frame through the second rubber strip and the first support rod, that is, the second rubber strip, the first support rod and the inclined first rubber strip are used to change the vibration force transmission direction and transmission position of the curtain wall panel, and a relatively stable mounting frame is used to effectively resist the vibration force, thereby greatly improving the earthquake resistance effect.

[0021] Optionally, a strip-shaped cavity is provided in the second rubber strip along a horizontal direction perpendicular to a surface of the mounting frame, a prestressed spring is provided in the strip-shaped cavity, and the prestressed spring is arranged along a horizontal direction perpendicular to the surface of the mounting frame.

[0022] By adopting the above technical solution, firstly, when the curtain wall panel has a vertical reciprocating displacement, the seismic force will be transmitted to the second rubber strip through the inclined first rubber strip, and the prestressed spring is compressed to buffer the seismic force; secondly, the prestressed spring is in a state of being compressed in real time, and the elastic force of the prestressed spring will be transmitted to the first rubber strip through the second rubber strip to buffer the seismic force in time and force the edge wrapping to fit with the arc edge, thereby improving the sealing effect.

[0023] Optionally, a shielding glass strip is provided at the movable gap. The shielding glass strip is arranged relative to the curtain wall panel away from the mounting frame. The width of the shielding glass strip is greater than the width of the movable gap, and the elastic waterproof structure is arranged between the shielding glass strip and the curtain wall panel.

[0024] By adopting the above technical solution, by providing the shielding glass strip to shield the movable gap, the widthability of the movable gap can be improved indirectly, that is, the distance between two adjacent curtain wall panels up and down can be increased, so as to meet the high displacement during the vibration of the curtain wall panel.

[0025] Optionally, the elastic waterproof structure includes a rubber water stop strip. The cross-section of the rubber water stop strip is U-shaped. The two sides of the rubber water stop strip are respectively bonded to the opposite surfaces of the shielding glass strip and the curtain wall panel through an adhesive.

[0026] By adopting the above technical solution, firstly, the rubber water stop strip can achieve the waterproof effect; secondly, the U-shaped setting can greatly improve the deformable range of the rubber water stop strip, so as to cope with the high displacement during the vibration of the curtain wall panel.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By providing a connecting rod connected by double ball heads, the seismic force received by the curtain wall panel will be converted into forcing the connecting rod to swing around the center of the ball formed by the cooperation of the first ball head and the first ball head seat, that is, the original vibrating displacement is amplified into a high displacement through the swing of the connecting rod, and the high displacement of the connecting rod will compress the limit spring to convert the seismic force into the elastic potential energy of the limit spring and the frictional heat energy of the first damping pad and the second damping pad, thereby extremely effectively reducing the seismic force and greatly improving the seismic resistance effect;

[0029] 2.

Detailed implementation manners

[0037] The following will further elaborate on this application in conjunction with the attached Figures 1-5 for a more detailed description of the present application.

[0038] Embodiment 1 of the present application discloses a high-displacement seismic curtain wall.

[0039] Referring to Figure 1 , the high-displacement seismic curtain wall includes a curtain wall panel 10, a mounting frame 20 fixed to a building, and a plurality of elastic connection assemblies 30 for connecting between the curtain wall panel 10 and the mounting frame 20. Among them, the mounting frame 20 can be a pre-embedded part or a post-installed skeleton structure, and the curtain wall panel 10 can be made of glass.

[0040] The edge of the curtain wall panel 10 is set as an arc edge, there is a movable gap between adjacent curtain wall panels 10, and an elastic waterproof structure 40 is provided between adjacent curtain wall panels 10. The elastic waterproof structure 40 is used to buffer the seismic force between adjacent curtain wall panels 10 to reduce the damage caused by the mutual collision of the curtain wall panels 10 due to vibration.

[0041] The elastic waterproof structure 40 includes two first rubber strips 61 arranged one above the other. The first rubber strips 61 are arranged in one-to-one correspondence with the curtain wall panels 10. A cavity is provided inside the first rubber strip 61. A plurality of elastic support ribs 63 are integrally formed in the inner cavity of the first rubber strip 61, and the elastic support ribs 63 are arranged in an inclined and cross-connected manner.

[0042] An arc-shaped edge wrapping 62 is integrally formed on one side of the first rubber strip 61. The edge wrapping 62 wraps the arc edge of the curtain wall panel 10 to achieve a waterproof effect. In order to increase the waterproof property, the edge wrapping 62 and the arc edge can also be bonded through waterproof glue; the adjacent sides of the two first rubber strips 61 are connected, and this connection form can be bonding or pure abutting.

[0043] When the curtain wall panel 10 vibrates and has a high displacement, the movement gap decreases, and the first rubber strip 61 is squeezed. The deformation force of the first rubber strip 61 is converted from the vibration force of the curtain wall panel 10, that is, it plays a role in buffering the vibration force to improve the seismic resistance effect.

[0044] As Figure 2 shown, the elastic connection assembly 30 includes a connecting rod 1, a sleeve 2, a first ball head seat 3, and a second ball head seat 5. There are two sleeves 2, and the two sleeves 2 are symmetrically arranged with the first ball head seat 3 as the center. One end of the two sleeves 2 is fixedly connected to the first ball head seat 3. And, for the convenience of installation, in this embodiment, the first ball head seat 3 is a split structure, that is, the first ball head seat 3 is composed of two hemispherical head seats, and the two hemispherical head seats are fixedly connected by flange bolts. The two sleeves 2 are respectively fixedly connected to one hemispherical head seat; the sleeve 2 has a conical inner cavity, and the inner diameter of the conical inner cavity gradually increases along the direction away from the first ball head seat 3. The axis of the conical inner cavity is horizontally perpendicular to the surface of the mounting frame 20; a connecting ring 21 is fixed at the mouth of the sleeve 2 far from the curtain wall panel 10, and the connecting ring 21 is bolted to the mounting frame 20.

[0045] The connecting rod 1 passes through the two sleeves 2. Under normal conditions, the connecting rod 1 is coaxially arranged with the conical inner cavity. A second ball head 12 is fixed at the end of the connecting rod 1 far from the mounting frame 20, and a first ball head 11 is fixed in the middle of the connecting rod 1. The first ball head 11 and the first ball head seat 3 are connected by a first damping pad 31, so that the connecting rod 1 can swing around the center of the ball of the first ball head 11. A plurality of limiting springs 4 are arranged in the conical inner cavity at intervals circumferentially around the axis of the conical inner cavity. The limiting springs 4 are used to force the connecting rod 1 and the sleeve 2 to maintain a coaxial state. The specific installation method is that the end of the limiting spring 4 can be abutted or welded to the inner wall of the sleeve 2 or the outer wall of the connecting rod 1. If it is abutted, in order to increase the stability of the force application point position of the limiting spring 4, abutting grooves can be provided on the inner wall of the sleeve 2 or the outer wall of the connecting rod 1.

[0046] A damping arc plate 13 is fixed to the end of the connecting rod 1 away from the second ball head 12. A spherical surface groove 201 is formed on the surface of the mounting bracket 20 corresponding to the damping arc plate 13. The center of curvature of the spherical surface groove 201 is located at the center of the circle of the first ball head 11. A third damping pad 202 is covered on the groove surface of the spherical surface groove 201. The damping arc plate 13 and the third damping pad 202 are always in a butting state.

[0047] A mounting seat 101 is installed on the back surface of the curtain wall panel 10. The specific installation method can be that the mounting seat 101 is fixedly connected through bolts passing through the curtain wall panel 10. The second ball head seat 5 is a split structure, that is, the second ball head seat 5 is also composed of two hemispherical head seats. The second ball head seat 5 is bolted to the mounting seat 101. The second ball head 12 and the second ball head seat 5 are connected in cooperation through a second damping pad 51.

[0048] The implementation principle of Embodiment 1 is as follows: When the curtain wall panel 10 is displaced due to wind pressure or seismic vibration force, the displacement of the curtain wall panel 10 forces the connecting rod 1 to swing around the center of the ball formed by the cooperation of the first ball head 11 and the first ball head seat 3. The connecting column mainly plays a role in amplifying the displacement, so as to amplify the displacement of the vibration of the curtain wall panel 10 into a high displacement through the swing of the connecting rod 1. And the high displacement of the connecting rod 1 will compress the limiting spring 4, so as to convert the vibration force into the elastic potential energy of the limiting spring 4, that is, the limiting spring 4 plays a role in buffering the vibration force. When the first ball head 11 and the second ball head 12 rotate, it causes the first damping pad 31 and the second damping pad 51 to generate heat due to friction, so as to convert the vibration force into frictional heat energy for consumption, thereby extremely effectively reducing the vibration force and greatly improving the seismic resistance effect.

[0049] At the same time, the swing of the connecting rod 1 also amplifies the relative displacement stroke of the damping arc plate 13 and the third damping pad 202, and generates heat due to friction between the damping arc plate 13 and the third damping pad 202, so as to greatly reduce the vibration force received by the curtain wall panel 10, thereby further improving the seismic resistance effect.

[0050] Embodiment 2

[0051] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 3 shown, a plurality of preloading bolts 22 are passed through the sleeve 2. The preloading bolts 22 are arranged in one-to-one correspondence with the limiting springs 4. The specific connection form is that the preloading bolts 22 pass through the sleeve 2, the preloading bolts 22 are threadedly connected with the sleeve 2, the preloading bolts 22 are coaxially arranged with the limiting springs 4, one end of the preloading bolts 22 is located outside the sleeve 2, and the other end of the preloading bolts 22 is located in the conical inner cavity and abuts against the end of the limiting spring 4 away from the connecting rod 1.

[0052] By providing the preloading bolts 22, the pre-tension force of the limiting spring 4 can be adjusted to adapt to different building environments.

[0053] Example 3

[0054] The difference between Example 3 and Example 1 is that, as Figure 4 shown, the elastic waterproof structure 40 further includes a second rubber strip 64. The second rubber strip 64 is horizontally perpendicular to the surface of the mounting frame 20. A strip-shaped cavity is provided in the second rubber strip 64. The strip-shaped cavity is arranged horizontally perpendicular to the surface of the mounting frame 20. A prestressed spring 65 is provided in the strip-shaped cavity. The prestressed spring 65 is arranged horizontally perpendicular to the surface of the mounting frame 20. The prestressed spring 65 is in a compressed state, and both ends of the prestressed spring 65 press against the inner wall of the strip-shaped inner cavity respectively.

[0055] The first rubber strip 61 is inclined, and there is an included angle of 120° between the first rubber strip 61 and the second rubber strip 64.

[0056] One side of the second rubber strip 64 is connected to the side edges of the two first rubber strips 61 together. This connection form can be integrally formed connection. A snap-in sleeve 68 is integrally formed on the other side of the second rubber strip 64. A first support rod 66 is vertically fixed on the surface of the mounting frame 20. A snap-in head 67 is provided at the end of the first support rod 66. The snap-in sleeve 68 and the snap-in head 67 are elastically snap-fitted.

[0057] First, when the curtain wall panel 10 vibrates and has a large displacement, resulting in a reduction in the movable gap, that is, when the curtain wall panel 10 has a vertical reciprocating displacement, the vibration force will be transmitted to the second rubber strip 64 through the inclined first rubber strip 61. Then, the vibration force acts vertically on the mounting frame 20 through the second rubber strip 64 and the first support rod 66, so as to utilize the relatively stable mounting frame 20 to effectively resist the vibration force, thereby greatly improving the seismic resistance effect.

[0058] At the same time, the prestressed spring 65 is compressed to buffer the vibration force.

[0059] Secondly, since the prestressed spring 65 is in a state of being compressed in real time, therefore, under normal conditions (when there is no vibration), the elastic force of the prestressed spring 65 will be transmitted to the first rubber strip 61 through the second rubber strip 64, forcing the edge wrapping 62 to fit with the arc edge, thereby improving the sealing effect.

[0060] Example 4

[0061] The difference between Example 4 and Example 1 is that, as Figure 5As shown, a second support rod 71 is vertically fixed to the surface of the mounting bracket 20. The second support rod 71 passes through the movable gap. A shielding glass strip 7 is fixed to the end of the second support rod 71. The shielding glass strip 7 is arranged relative to the curtain wall panel 10 away from the mounting bracket 20, so that there is a horizontal gap between the surface of the shielding glass strip 7 and the curtain wall panel 10. At the same time, the width of the shielding glass strip 7 is greater than the width of the movable gap, so that the shielding glass strip 7 blocks the movable gap.

[0062] The elastic waterproof structure 40 includes a rubber water stop strip 69. The cross-section of the rubber water stop strip 69 is U-shaped. The two sides of the rubber water stop strip 69 are respectively bonded to the opposite surfaces of the shielding glass strip 7 and the curtain wall panel 10 through an adhesive. This adhesive can be selected as silicone weather-resistant adhesive.

[0063] By providing the shielding glass strip 7, a relatively wide movable gap can be blocked, increasing the aesthetic degree. At the same time, it means that the movable gap can be set larger, and a larger movable gap means that a larger high displacement range of the curtain wall panel 10 can be satisfied, thereby indirectly improving the seismic resistance effect.

[0064] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
