Description

Technical Field

[0001] This invention belongs to the field of building curtain wall connection technology, specifically relating to a structure for connecting a high-rise building curtain wall system with an all-steel main structure. Background Technology

[0002] A curtain wall is the exterior cladding of a building, primarily composed of panels and a supporting structural system for installing the panels. It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. Glass curtain walls are a major form of expression in modern architecture, and they constitute a significant proportion of all curtain walls, especially in buildings under 200 meters in height, where framed glass curtain walls are still the primary type. A curtain wall includes columns and beams, arranged in a grid pattern. Common structural forms of glass curtain walls include exposed frame, concealed frame, semi-concealed frame, and point-supported systems.

[0003] The curtain wall panels and supporting structure system require a certain displacement capacity relative to the main structure or a certain deformation capacity, and are building envelope or decorative structures that do not bear the load of the main structure. During installation, to achieve a flat and aesthetically pleasing appearance, the inter-floor structure and curtain wall panel connecting components need to be concealed. This is typically achieved by installing a curtain wall back panel, located within the grid formed by the curtain wall mullions and beams. The back panel has folded edges around its perimeter, leaving gaps between these edges and the mullions and beams. The folded edges of the back panel are connected to the base brackets using angle brackets, and foam rods are used to seal the perimeter. Existing glass curtain walls lack automatic wind pressure relief or have weak wind pressure relief capabilities. The wind pressure acts uniformly on each glass panel, causing excessive pressure on the glass panels and the all-steel main structure. When localized stress concentrations or pressure concentrations exceed the load-bearing limit, accidents are highly likely to occur.

[0004] The existing all-glass curtain wall and all-steel structure have problems with poor connection strength and lack of flexible support connection, and usually do not have earthquake resistance and wind pressure resistance. Summary of the Invention

[0005] To address the issues of poor connection strength and lack of flexible support in existing all-glass curtain walls and all-steel main structures, this invention provides a structure that connects a high-rise building curtain wall system to an all-steel main structure. Through the interconnected buffering relationship of the four top corners on the inner side of the all-glass curtain wall, the curtain wall has deformation adaptability and strong resistance to wind pressure and earthquakes.

[0006] The solution adopted by this invention to solve its technical problem is: a structure connecting a high-rise building curtain wall system to an all-steel main structure, including a glass curtain wall, a steel main structure and flexible connectors. A fixed bushing is fixed to the rear wall of the glass curtain wall, and flexible connectors are respectively connected at the four apex positions corresponding to the fixed bushing and the steel main structure. The flexible connectors include a rear support and a front support. A balance air rod assembly is connected between the rear support and the front support. The rear end of the balance air rod assembly is fixed to the rear support, and the front end is hinged to the front support through a ball joint.

[0007] When any vertex on the upper side of the fixed support frame is subjected to pressure, the other vertex on the upper side also retracts in the same direction, thereby relieving the pressure on the upper corner and ensuring that the left and right vertices on the upper side are subjected to pressure synchronously. When any vertex on the upper side of the fixed support frame is subjected to pressure, the two lower vertices move in opposite directions, that is, the two lower vertices move outward, resulting in an overall pattern of the upper part moving inward and the lower part moving outward, and vice versa. This characteristic of asymmetrical vertical movement and symmetrical horizontal synchronous movement allows it to both distribute the pressure of a single vertices and create airflow channels when a single glass wall tilts vertically, thereby achieving the effect of relieving wind pressure. By achieving localized pressure relief of the glass curtain wall in the above manner, the impact of hurricane pressure can be effectively reduced, ensuring the overall structural stability.

[0008] The balance rod assembly includes a cylinder, a free piston, and a piston rod. The free piston is fitted into the middle of the cylinder body, dividing the cylinder body into a front chamber and a rear chamber. A front balance spring is fitted in the front chamber, and a rear balance spring is fitted in the rear chamber. A front chamber air pipe is led out from the front chamber, and a rear chamber air pipe is led out from the rear chamber. The piston rod, which is integrated with the free piston, is led out from the end positioning hole of the cylinder body, and its outer end is connected to the front support by a ball joint.

[0009] A ball is fixed to the outer end of the piston rod, and a ball seat is set in the center of the front support. The ball is fitted into the ball seat. The opening diameter of the ball seat is smaller than the diameter of the ball but larger than the diameter of the piston rod, so that the ball can rotate freely in the ball seat.

[0010] The flexible connectors located at the four apex positions of the fixed bushing are connector A, connector B, connector C, and connector D. Connectors A and D correspond to the two upper apex positions of the fixed bushing, while connectors B and C correspond to the two lower apex positions of the fixed bushing. The front chamber air pipe of connector A is connected to the front chamber air pipe of connector B, and the rear chamber air pipe of connector A is connected to the rear chamber air pipe of connector B. The front chamber air pipe of connector D is connected to the front chamber air pipe of connector C, and the rear chamber air pipe of connector D is connected to the rear chamber air pipe of connector C. The front chamber air pipe of connector A is connected to the rear chamber air pipe of connector D, and the rear chamber air pipe of connector A is connected to the front chamber air pipe of connector D. The front chamber air pipe of connector B is connected to the rear chamber air pipe of connector C, and the rear chamber air pipe of connector B is connected to the front chamber air pipe of connector C.

[0011] Furthermore, the air pipes of connectors A, B, C, and D can be sequentially connected to the same balance assist cylinder. The balance assist cylinder includes a closed cylinder body with a compound piston installed in the middle of its inner side. The compound piston divides the cylinder body into a front chamber and a rear chamber. The compound piston contains an inner cylinder, in which an inner piston is installed. The inner piston is connected to the ground of the inner cylinder by a support spring. A piston tube is connected to the center of the inner piston. One end of the piston tube communicates with the outside, and the other end communicates with the inner cylinder.

[0012] The connection relationships between the air pipes of connectors A, B, C, and D and the balance assist cylinder are as follows: the front chamber air pipe of connector A is connected to the rear chamber air pipe of the balance assist cylinder, and the rear chamber air pipe of connector A is connected to the front chamber air pipe of the balance assist cylinder; the front chamber air pipe of connector D is connected to the front chamber air pipe of the balance assist cylinder, and the rear chamber air pipe of connector D is connected to the rear chamber air pipe of the balance assist cylinder; the front chamber air pipe of connector B is connected to the rear chamber air pipe of the balance assist cylinder, and the rear chamber air pipe of connector B is connected to the front chamber air pipe of the balance assist cylinder; the front chamber air pipe of connector C is connected to the front chamber air pipe of the balance assist cylinder, and the rear chamber air pipe of connector C is connected to the rear chamber air pipe of the balance assist cylinder.

[0013] Connecting gaskets are fixed at the fixing holes at the four apex corners of the fixed bushing. The front supports of each flexible connector are fixed to the corresponding apex corner of the fixed bushing via the connecting gaskets.

[0014] The beneficial effects of the present invention are: the connection between the all-glass curtain wall and the all-steel structure is strong and has a flexible support connection, which has a multi-directional free swing function and a strong earthquake resistance and wind pressure resistance function.

[0015] When any vertex on the upper side of the fixed support frame is subjected to pressure, the other vertex on the upper side also retracts in the same direction, thereby relieving the pressure on the upper corner and ensuring that the left and right vertices on the upper side are subjected to pressure synchronously. When any vertex on the upper side of the fixed support frame is subjected to pressure, the two lower vertices move in opposite directions, that is, the two lower vertices move outward, resulting in an overall pattern of the upper part moving inward and the lower part moving outward, and vice versa. This characteristic of asymmetrical vertical movement and symmetrical horizontal synchronous movement allows it to both distribute the pressure of a single vertices and create airflow channels when a single glass wall tilts vertically, thereby achieving the effect of relieving wind pressure. By achieving localized pressure relief of the glass curtain wall in the above manner, the impact of hurricane pressure can be effectively reduced, ensuring the overall structural stability.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1: A kind of Figure 1The high-rise building curtain wall system shown is connected to the all-steel main structure. This structure is an improvement on the existing connection between all-glass curtain walls and all-steel main structures, which suffers from poor connection strength and lack of flexible support. The connection structure between the all-glass curtain wall and the all-steel main structure is designed to solve this problem. It mainly includes glass curtain wall 1, steel main structure 2, and flexible connectors 3. Through the interconnected buffering relationship of the four top corners on the inner side of the all-glass curtain wall, the curtain wall has deformation adaptability and strong resistance to wind pressure and earthquakes.

[0020] Specifically, in such Figures 1-3 The glass curtain wall 1 shown has a fixed support frame 17 fixed to its rear wall. Based on the fixed support frame 17, flexible component fixing holes are provided at the four top corners of the fixed support frame 17. Flexible component fixing holes 21 are also provided at corresponding positions on the steel main structure 2. Flexible connectors 3 are connected at the four top corners between the fixed support frame 17 and the steel main structure 2.

[0021] like Figure 4 The flexible connector 3 shown includes a rear support 4 and a front support 5. The rear support is installed with the fixing hole of the steel main structure 2 through a fixing screw 16, and the front support is installed with the fixing hole of the fixing bushing 17 through a fixing screw 16. A balance rod assembly is connected between the rear support 4 and the front support 5. The rear end of the balance rod assembly is fixed to the rear support 4, and the front end is hinged to the front support 5 through a ball joint.

[0022] Figure 4 As can be seen, the balance rod assembly includes a cylinder 6, a free piston 7, and a piston rod 8. The free piston 7 is fitted into the middle of the cylinder 6, dividing the cylinder into a front chamber and a rear chamber. A front balance spring 9 is fitted into the front chamber, and a rear balance spring 10 is fitted into the rear chamber. A front chamber air pipe 11 leads out from the front chamber, and a rear chamber air pipe 12 leads out from the rear chamber. The piston rod, which is integrally connected to the free piston 7, extends from the end positioning hole of the cylinder 6, and its outer end is connected to the front support 5 via a ball joint. Specifically, a ball 14 is fixed to the outer end of the piston rod 7, and a ball seat 13 is provided at the center of the front support 5. The ball 14 is fitted into the ball seat 13. The opening diameter of the ball seat is smaller than the diameter of the ball but larger than the diameter of the piston rod, allowing the ball to rotate freely within the ball seat.

[0023] like Figure 3 As shown, after the flexible connectors 3 are installed at the four corners of the fixed bushing 17, the flexible connectors 3 remain parallel to the surface of the cylinder body structure 2 in the initial state.

[0024] like Figure 5As shown, the flexible connectors 3 located at the four apex positions of the fixed bushing 17 are connector A, connector B, connector C, and connector D, respectively. Connectors A and D correspond to the two upper apex positions of the fixed bushing 17, while connectors B and C correspond to the two lower apex positions of the fixed bushing 17. Figure 5 The connection relationships between each flexible connection 3 are shown as follows: the anterior chamber air pipe of connector A is connected to the anterior chamber air pipe of connector B, and the rear chamber air pipe of connector A is connected to the rear chamber air pipe of connector B; the anterior chamber air pipe of connector D is connected to the anterior chamber air pipe of connector C, and the rear chamber air pipe of connector D is connected to the rear chamber air pipe of connector C; the anterior chamber air pipe of connector A is connected to the rear chamber air pipe of connector D, and the rear chamber air pipe of connector A is connected to the anterior chamber air pipe of connector D; the anterior chamber air pipe of connector B is connected to the rear chamber air pipe of connector C, and the rear chamber air pipe of connector B is connected to the anterior chamber air pipe of connector C.

[0025] Based on the above connection, when any vertex on the upper side of the fixed bushing 17 is subjected to pressure, the other vertex on the upper side also retracts in the same direction, thereby relieving the pressure on the upper corner and maintaining synchronous pressure on the left and right vertices on the upper side. When any vertex on the upper side of the fixed bushing 17 is subjected to pressure, the two vertices on the lower side move in opposite directions, that is, the two vertices on the lower side move outward, and the whole structure presents an upper part moving inward and a lower part moving outward, and vice versa. This characteristic of asymmetrical vertical movement and symmetrical synchronous horizontal movement allows it to both share the pressure of a single vertices and allow individual glass walls to tilt vertically and vertically, forming air passages, thereby achieving the effect of relieving wind pressure. Existing all-glass curtain walls do not have an automatic wind pressure relief function. The wind pressure acts on each glass wall as a whole, causing the glass walls and the all-steel main structure to bear excessive pressure. When the stress concentration or pressure concentration area exceeds the load-bearing limit, accidents are very likely to occur. This embodiment achieves local glass curtain wall pressure relief through the above method, which can effectively reduce the impact of hurricane pressure and ensure the stability of the overall structure.

[0026] Because each flexible connection has a left rear balance spring on the inside of the cylinder, each independent plastering unit can quickly recover after deformation. This structure also gives the curtain wall seismic resistance.

[0027] Example 2: Based on Example 1, as a further supplementary consideration, the air pipes of connectors A, B, C, and D can be sequentially connected to the same balance assist cylinder 23. For example... Figure 6 As shown, the balance assist cylinder 23 includes a closed cylinder body, in which a compound piston 24 is fitted in the middle of its inner side. The compound piston divides the cylinder body into a front chamber and a rear chamber. The compound piston contains an inner cylinder, in which an inner piston is fitted. The inner piston is connected to the ground of the inner cylinder by a support spring. A piston tube 25 is connected to the center of the inner piston. One end of the piston tube communicates with the outside, and the other end communicates with the inner cylinder.

[0028] The connection relationships between the air pipes of connectors A, B, C, and D and the balance assist cylinder 23 are as follows: the front chamber air pipe of connector A is connected to the rear chamber air pipe of balance assist cylinder 23, and the rear chamber air pipe of connector A is connected to the front chamber air pipe of balance assist cylinder 23; the front chamber air pipe of connector D is connected to the front chamber air pipe of balance assist cylinder 23, and the rear chamber air pipe of connector D is connected to the rear chamber air pipe of balance assist cylinder 23; the front chamber air pipe of connector B is connected to the rear chamber air pipe of balance assist cylinder 23, and the rear chamber air pipe of connector B is connected to the front chamber air pipe of balance assist cylinder 23; the front chamber air pipe of connector C is connected to the front chamber air pipe of balance assist cylinder 23, and the rear chamber air pipe of connector C is connected to the rear chamber air pipe of balance assist cylinder 23.

[0029] This embodiment, while having the same functions as Embodiment 1, also utilizes the balancing assist cylinder 23 to balance and adjust the air pressure of each cylinder, and can achieve overall buffer adjustment, which is beneficial for the simultaneous compression deformation of each top corner of the entire curtain wall, thereby improving the overall elastic compression degree.

[0030] Example 3: Based on the above examples, connecting gaskets 18 are fixed at the fixing holes at the four corners of the fixed bushing 17. The front supports 5 of each flexible connector are fixed to the corresponding corners of the fixed bushing 17 by the connecting gaskets 18.

[0031] Example 4: An inner hole 20 is provided at the center of the fixing holes at the four corners of the fixed bushing 17, and an outer hole 19 is provided at the center of the connecting gasket 18. The diameter of the outer hole 19 is smaller than the diameter of the inner hole 20. The outer hole of the integrated gasket and the inner control form a semi-closed inner cavity. A safety post 27 is fitted into this semi-closed inner cavity. The diameter of the safety post is larger than the diameter of the outer hole 19. The safety post 27 is fixed to the sphere 14 as a whole by a rope end 26. This example provides protection to prevent excessive internal pressure in the curtain wall from exceeding the strength of the joint.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
