Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, specifically relating to a clamp for cable net curtain walls with high deformation and displacement adaptability. Background Technology

[0002] Cable-net curtain walls are widely used in large public buildings, commercial complexes, and other venues due to their advantages such as lightness, aesthetics, large span, and good spatial transparency. However, during use, cable-net curtain walls are subject to deformation and displacement due to factors such as wind vibration, temperature changes, and structural settlement. Meanwhile, as the core enclosure component of the curtain wall, the stability, sealing, and shock absorption of the glass during installation directly affect the safety and durability of the curtain wall.

[0003] Problems with existing technology: Traditional clamps mostly use rigid connection structures, which can only withstand limited linear deformation. They cannot effectively absorb the non-uniform deformation caused by the multi-angle rotational displacement of the cable net and dynamic wind vibration, resulting in significant stress concentration at the connection between the clamp and the glass. Under long-term action, this can easily lead to cracking of the glass edge, loosening of clamp bolts, or even fatigue damage at the connection point of the cable net.

[0004] Furthermore, the existing clamps' buffer structures are mostly single rubber pads, which have poor elastic modulus and simple structural design. They cannot effectively buffer the impact of external forces such as wind vibration and construction collisions on the glass, resulting in a high risk of glass breakage. At the same time, they lack a dedicated damping energy dissipation mechanism, so the kinetic energy generated by wind vibration cannot be effectively consumed and is prone to accumulate inside the structure, accelerating the fatigue and aging of the clamps. Utility Model Content

[0005] The purpose of this invention is to provide a clamp for cable mesh curtain walls with high adaptability to deformation and displacement, which can simultaneously absorb the linear deformation and rotational displacement of the cable mesh curtain wall to avoid stress concentration; improve the positioning accuracy and fixing stability of glass installation to prevent horizontal displacement and sliding of the glass; and enhance the shock absorption and buffering performance of the clamp to reduce the impact damage of external forces on the glass.

[0006] The specific technical solution adopted by this utility model is as follows: A clamp for a cable net curtain wall with high deformation and displacement adaptability includes a cable net adapter, a first buffer rod is fixed on one side of the cable net adapter, a first glass clamp is provided at the other end of the first buffer rod, and a second glass clamp is provided on the outside of one side of the first glass clamp by bolts. The first glass clamp and the second glass clamp each have four square-shaped limiting pads on opposite sides; Each side of the limiting pad is provided with at least four arc-shaped pads, each arc-shaped pad having a hollow annular structure, and a suction cup is provided on the hollow inner side of each arc-shaped pad.

[0007] Among the four limiting pads, the adjacent surfaces of two adjacent limiting pads are tightly fitted together, and each of the adjacent edges where the two adjacent limiting pads are fitted together is provided with a limiting protrusion.

[0008] The arc-shaped pad has multiple anti-slip grooves equidistantly spaced along its circumference on one side.

[0009] A sealing strip is provided on one side of the limiting pad along its circumference edge.

[0010] One side of the cable net adapter is provided with a detachable second buffer rod, and the other end of the second buffer rod is provided with a universal ball joint. One end of the universal ball joint is provided with a connecting plate, and the four corners of one side of the connecting plate are provided with fixing holes.

[0011] The first and second buffer rods each include a sleeve, and a plug rod is slidably mounted inside the sleeve. A disc spring connected to the plug rod is provided inside the sleeve.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a sleeve-insertion rod-disc spring structure for the first and second buffer rods to achieve the buffering and absorption of linear deformation displacement. Simultaneously, the damping friction between the insertion rod and the sleeve dissipates wind vibration energy. The universal ball joint can rotate flexibly, effectively absorbing the rotational displacement of the cable net curtain wall and effectively solving the problem of stress concentration in traditional clamps.

[0013] This utility model uses four square limiting pads to form a precise positioning space. With the limiting protrusions of the adjacent pads, it effectively limits the horizontal displacement of the glass and improves the installation positioning accuracy. The anti-slip groove of the arc pad enhances the friction with the glass, and the suction cup forms a secondary fixation through adsorption, providing double protection to prevent the glass from sliding or loosening.

[0014] This invention utilizes a rubber arc-shaped gasket with excellent elasticity to buffer against external impacts such as wind vibration and collisions. The hollow ring structure ensures uniform stress distribution on the glass, preventing localized stress concentration. The elastic deformation of the suction cup works in conjunction with the arc-shaped gasket to further reduce damage to the glass from external forces and lower the probability of glass breakage.

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figures 1-3 As shown, a clamp for a cable net curtain wall with high deformation and displacement adaptability includes a cable net adapter 1. A first buffer rod 2 is fixed on one side of the cable net adapter 1, and a first glass clamp 3 is provided at the other end of the first buffer rod 2. A second glass clamp 4 is provided on the outside of one side of the first glass clamp 3 by bolts. Four square-shaped limiting pads 5 are provided on opposite sides of the first glass clamp 3 and the second glass clamp 4. Each side of the limiting pad 5 is provided with at least four arc-shaped pads 6. The arc-shaped pads 6 are made of rubber and have a hollow ring structure. The hollow inner side of the arc-shaped pads 6 is provided with a suction cup 8. Among the four limiting pads 5, the adjacent surfaces of two adjacent limiting pads 5 are tightly fitted together, and the adjacent edges of two adjacent limiting pads 5 that are fitted together are provided with limiting protrusions. The arc-shaped gasket 6 has multiple anti-slip grooves 7 evenly spaced along the circumference on one side; the limiting pad 5 has a sealing strip 9 along its circumferential edge on one side.

[0019] Based on the above structure, the combination of the limiting pad 5 and the limiting protrusion improves the stability and accuracy of glass installation and enhances the practicality of the equipment. The four square limiting pads 5 form a precise positioning space, which, together with the limiting protrusions on the adjacent surfaces, can effectively limit the horizontal displacement of the glass and significantly improve the positioning accuracy of glass installation. The limiting protrusions enhance the connection stability between the limiting pads 5, preventing the pads from shifting due to external forces and further improving the overall stability of the glass fixing. The first glass clamp 3 and the second glass clamp 4 are brought close to each other with bolts to stabilize and fix the glass; the arc-shaped gasket 6 and the suction cup 8 work together. The arc-shaped gasket 6 is made of rubber and has excellent elasticity and shock absorption performance. It can buffer the impact of external forces such as wind vibration and collision on the glass and effectively protect the glass from breakage. The hollow ring structure has a uniform contact area with the glass surface, which disperses the force and reduces the local stress concentration of the glass. The suction cup 8 is located on the hollow inner side of the arc pad 6. It forms a secondary fixation with the glass through adsorption, which not only enhances the connection between the glass and the clamp, but also helps to reduce shock and buffer through the elastic deformation of the suction cup 8. The sealing strip 9 fits against the perimeter edge of the limiting pad 5, filling the gap between the clamp and the glass, significantly improving the sealing of the connection, effectively preventing moisture, dust and other impurities from entering, protecting the glass edge and the internal components of the clamp, and extending the service life.

[0020] like Figures 1-2 As shown, a detachable second buffer rod 10 is provided on one side of the cable net adapter 1, and a universal ball joint 11 is provided at the other end of the second buffer rod 10. A connecting plate 12 is provided at one end of the universal ball joint 11, and fixing holes are provided at the four corners of one side of the connecting plate 12.

[0021] Based on the above structure, the universal ball joint 11 is designed to absorb the overall displacement of the rotating cable net, thereby improving the stability of the equipment.

[0022] like Figures 1-2 As shown, the first buffer rod 2 and the second buffer rod 10 include a sleeve, and a plug rod is installed inside the sleeve with damping sliding. A disc spring connected to the plug rod is provided inside the sleeve.

[0023] According to the above structure, during operation, the insert rod and the sleeve undergo overall damped sliding. When the insert rod compresses the disc spring inside the sleeve, the contact surfaces of the insert rod and the sleeve rub against each other, which consumes energy under wind vibration to a certain extent.

[0024] The working principle of this utility model is as follows: when the cable net curtain wall generates linear deformation displacement, the insert rods of the first buffer rod 2 and the second buffer rod 10 slide along the sleeve damping, compressing the disc spring, buffering the displacement through the elastic deformation of the disc spring, and at the same time, the friction between the insert rod and the sleeve consumes wind vibration energy. When the cable net curtain wall undergoes rotational displacement, the universal ball joint 11 rotates flexibly to absorb the rotational displacement and avoid stress concentration; When subjected to external forces such as wind vibration, the elastic deformation of the arc-shaped pad 6 and the adsorption and buffering effect of the suction cup 8 work together to reduce the impact of external forces on the glass, and the anti-slip groove 7 enhances friction and prevents the glass from sliding. The sealing strip 9 always maintains a tight fit with the glass, preventing moisture and dust from entering.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
