Description

Technical Field

[0001] This application relates to the field of curtain wall technology, specifically to a flexible adaptive clamp for carbon fiber curtain wall cables and a carbon fiber cable mesh. Background Technology

[0002] Carbon fiber cable-stayed facades are a new type of lightweight, high-strength building envelope system, primarily composed of carbon fiber cable nets and glass panels. Leveraging the excellent lightweight, high strength, and high tensile strength of carbon fiber, it offers significant structural performance advantages compared to traditional steel cable-stayed facades, making it suitable for the construction needs of modern building curtain walls that require large spans, lightweight construction, and high transparency. While carbon fiber cables, as the core load-bearing component of this facade system, possess excellent tensile strength, the material itself has inherent defects. Its shear strength is extremely low, and it is highly sensitive to localized stress concentration, making it prone to structural damage due to shear stress and localized stress concentration. This dictates that the design logic of the connectors for carbon fiber cable-stayed facades cannot be followed for traditional steel cable-stayed facades.

[0003] The cross-node clamps (cable clamps) of horizontal and vertical cables are the core force-transmitting connection components of carbon fiber cable curtain walls. They play a crucial role in fixing glass panels, positioning horizontal and vertical cables, and transferring loads. The overall structural stiffness of the cable clamps and the geometric characteristics of the interface with the cables directly determine the shear stress distribution on the surface of the carbon fiber cables, which are the core factors affecting the overall structural stability and service life of the curtain wall.

[0004] Currently, traditional cable clamps for cable-stayed curtain walls are designed for steel cables. The shear strength of steel cables is only slightly lower than their tensile strength, resulting in balanced mechanical properties. Therefore, existing cable clamps generally adopt a rigid extrusion structure, often a straight cylindrical duct structure. When this type of rigid cable clamp is applied to carbon fiber cable-stayed curtain walls, it suffers from many unavoidable technical defects and cannot adapt to the mechanical properties and construction process requirements of carbon fiber cables.

[0005] First, the existing rigid cable clamps, with their straight cylindrical design, cannot match the low shear stiffness and nonlinear interface response of carbon fiber cables. This leads to significant stress concentration in the contact area between the clamp and the cable, exceeding the shear capacity of the carbon fiber cable and causing localized shear failure. Second, the integrally cast alloy steel rigid clamps lack radial elastic deformation capability. During the curtain wall's service life, when the carbon fiber cable undergoes axial micro-deformation due to temperature changes and wind vibration, the clamps cannot provide an effective stress release path for the cable. Shear damage continues to accumulate at the carbon fiber bundle interface, gradually exacerbating cable structure damage and significantly shortening the curtain wall's service life.

[0006] Meanwhile, traditional cable clamps are unsuitable for the unique construction process of carbon fiber cable-stayed curtain walls. Conventional steel cable curtain walls allow for preliminary installation of cable clamps after vertical cable tensioning, followed by final tightening after horizontal cable tensioning, providing ample installation space and convenient construction. However, the construction process for carbon fiber cable-stayed curtain walls differs significantly. To avoid compression damage and stress concentration issues caused by the cable clamps to the carbon fiber cables during tensioning, cable clamp installation can only commence after all horizontal and vertical cables have been tensioned. However, once the horizontal and vertical cables are tensioned and set, the working space at the intersections is severely limited, making it difficult to assemble the compact, traditional, integral rigid cable clamps, resulting in extremely poor construction feasibility.

[0007] Therefore, there is an urgent need to develop a flexible adaptive clamp that can adapt to the specific mechanical properties of carbon fiber cables and the curtain wall construction process, buffer stress concentration, and adapt to narrow construction spaces.

[0008] In view of the above, this application is hereby submitted. Summary of the Invention

[0009] This application provides a flexible adaptive clamp for carbon fiber curtain wall cables and a carbon fiber cable mesh to solve the technical problem that existing clamps are not suitable for carbon fiber curtain wall cables.

[0010] The primary objective of this application is to provide a flexible adaptive clamp for carbon fiber curtain wall cables, the technical solution of which is as follows: A flexible adaptive clamp for carbon fiber curtain wall cables includes multiple clamping blocks, each of which is detachably connected. The clamping blocks enclose a transverse groove and a longitudinal groove. Both the transverse groove and the longitudinal groove include a spherical groove and two gradually expanding channels. The two gradually expanding channels are located on opposite sides of the spherical groove and are connected to the spherical groove. In the direction from the spherical groove to the gradually expanding channels, the cross-section of the gradually expanding channels gradually increases.

[0011] Optionally, each of the clamping blocks includes a first clamping block, a second clamping block, a third clamping block, and a fourth clamping block; The second clamping block and the third clamping block are located between the first clamping block and the fourth clamping block, and the second clamping block and the third clamping block are arranged sequentially along the length direction of the first clamping block; A transverse groove is formed between the first clamping block, the second clamping block, and the third clamping block; The longitudinal groove is formed between the second clamping block, the third clamping block, and the fourth clamping block.

[0012] Optionally, a circumferential semi-transverse groove is provided on the first clamping block. The circumferential semi-transverse groove is a semi-groove formed by cutting the transverse groove through the plane containing its axis. The second clamping block and the third clamping block are respectively provided with transverse side grooves. The transverse side grooves on the second clamping block and the third clamping block are spliced ​​together to form another circumferential semi-transverse groove. This circumferential semi-transverse groove and the circumferential semi-transverse groove on the first clamping block are spliced ​​together to form a complete transverse groove.

[0013] Optionally, the fourth clamping block has a circumferential semi-longitudinal groove, which is a semi-groove formed by cutting the longitudinal groove through the plane containing its axis. Both the second and third clamping blocks are provided with longitudinal side grooves. The longitudinal side grooves on the second and third clamping blocks are spliced ​​together to form another circumferential semi-longitudinal groove. This axial semi-longitudinal groove and the circumferential semi-longitudinal groove on the fourth clamping block are spliced ​​together to form a complete longitudinal groove.

[0014] Optionally, the flexible adaptive clamps for carbon fiber curtain wall cables include rubber pads; A glass support plate is provided on the side of the fourth clamping block opposite to the first clamping block; The rubber pad is fitted onto the glass support plate.

[0015] Optionally, the flexible adaptive clamp for carbon fiber curtain wall cables includes connectors, rubber rings, and glass clamps; The fourth clamping block is provided with connecting claws; The connector has a screw and an end set at the end of the screw. The screw passes through the glass clamp and is connected to the connecting claw. The end is located on the side of the glass clamp away from the connecting claw. A clamping space is formed between the glass clamp and the connecting claw.

[0016] Optionally, the flexible adaptive clamps for carbon fiber curtain wall cables include rubber sheets; The rubber sheet is attached to the side of the fourth clamping block opposite to the first clamping block.

[0017] Optionally, the gradually expanding channel is a tapered hole with a cone angle of 10° to 12°.

[0018] The second objective of this application is to provide a carbon fiber cable mesh, the technical solution of which is as follows: A carbon fiber cable mesh, comprising: A plurality of transverse cables and a plurality of longitudinal cables are arranged in an alternating grid structure. Each of the transverse cables and longitudinal cables is provided with a plurality of elastic balls, and each elastic ball on the transverse cables and the plurality of longitudinal cables is opposite to the other. As described above, the flexible adaptive clamp for carbon fiber curtain wall cables has each clamping block fitted at the intersection of the transverse and longitudinal cables. The transverse groove is fitted onto one of the transverse cables, and the longitudinal groove is fitted onto one of the longitudinal cables. One of the two opposing elastic balls is embedded in the ball groove of the transverse groove, and the other is embedded in the ball groove of the vertical groove.

[0019] Optionally, the elastic ball comprises two hemispheres connected by a colloid, and the two hemispheres are fitted onto the transverse or longitudinal tension cable.

[0020] By adopting the above technical solution, this application has the following beneficial effects: The flexible adaptive clamp for carbon fiber curtain wall cables provided in this application forms transverse and longitudinal slots to accommodate horizontal and vertical cables through the splicing of multiple detachable clamp blocks. This detachable clamp block assembly structure overcomes the limitation of traditional integral cable clamps that cannot be assembled piece by piece. It allows for piece-by-piece assembly and forming even when all horizontal and vertical cables are tensioned and shaped, and the working space at intersections is limited. This perfectly adapts to the special construction sequence of carbon fiber cable curtain walls, where cable clamps must be installed after tensioning. It effectively solves the industry problem of traditional rigid cable clamps being unable to be assembled in confined spaces and having poor construction feasibility, significantly reducing construction difficulty and improving the efficiency and adaptability of curtain wall installation.

[0021] Abandoning the traditional straight-cylinder, single-cone-angle single-channel structure, this design employs a composite channel structure with a spherical groove and double-sided gradually expanding channels. The cross-section of the gradually expanding channels, extending from the spherical groove to both sides, gradually increases smoothly, enabling a continuous transition and fit between the clamps and the carbon fiber cable contact interface. Compared to the rigid compression contact of traditional rigid channels, this composite structure optimizes the stress distribution at the contact interface, avoids localized load concentration, effectively matches the low shear stiffness and nonlinear interface response characteristics of carbon fiber cables, and eliminates shear failure caused by localized stress exceeding the shear limit of carbon fiber. Furthermore, when the cables experience micro-deformation or angular deflection due to temperature changes, wind vibration disturbances, or other disturbances, the elastic spheres on the cables can adaptively adjust their position within the spherical groove. The gradually expanding channels prevent sharp stress concentrations at the cable openings, effectively dispersing shear stress, buffering localized stress concentrations, and preventing shear damage to the carbon fiber cables. This significantly improves the structural stability and service life of the carbon fiber cable-stayed wall.

[0022] Furthermore, the carbon fiber cable mesh provided in this application, through the cooperation of elastic balls and ball grooves with gradually expanding channels, can adapt to the slight deformation of the cables and buffer stress concentration. At the same time, it adopts a detachable splicing clamp structure, which can be assembled after the horizontal and vertical cables are tensioned. It not only adapts to the mechanical properties of carbon fiber cables, but also meets the construction requirements of carbon fiber cable curtain walls, and the overall structure is safe and reliable.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example 1 See Figures 1-5 As shown, this disclosure provides a flexible adaptive clamp for carbon fiber curtain wall cables, including multiple clamping blocks, each of which is detachably connected. The clamping blocks enclose a transverse groove 13 and a longitudinal groove 14. Both the transverse groove 13 and the longitudinal groove 14 include a spherical groove and two gradually expanding channels. The two gradually expanding channels are respectively disposed on opposite sides of the spherical groove, and the gradually expanding channels are connected to the spherical groove. In the direction from the spherical groove to the gradually expanding channels, the cross-section of the gradually expanding channels gradually increases.

[0030] The flexible adaptive clamp for carbon fiber curtain wall cables provided in this application forms a transverse groove 13 and a longitudinal groove 14 to accommodate the transverse cable 4 and the longitudinal cable 5 through the splicing of multiple detachable clamp blocks. This detachable clamp block assembly structure overcomes the limitation of traditional integral cable clamps that cannot be assembled piece by piece. It allows for piece-by-piece assembly and forming even when all horizontal and vertical cables are tensioned and shaped, and the working space at intersections is limited. This perfectly adapts to the special construction sequence of carbon fiber cable curtain walls, where cable clamps must be installed after tensioning. It effectively solves the industry problem of traditional rigid cable clamps being unable to be assembled in confined spaces and having poor construction feasibility, significantly reducing construction difficulty and improving the efficiency and adaptability of curtain wall installation.

[0031] Abandoning the traditional straight-cylinder, single-cone-angle single-channel structure, this design employs a composite channel structure with a spherical groove and double-sided gradually expanding channels. The cross-section of the gradually expanding channels extending from the spherical groove to both sides gradually increases smoothly, enabling a continuous transition and fit between the clamps and the carbon fiber cable contact interface. Compared to the rigid compression contact of traditional rigid channels, this composite structure optimizes the stress distribution at the contact interface, avoids localized load concentration, effectively matches the low shear stiffness and nonlinear interface response characteristics of carbon fiber cables, and eliminates shear failure caused by localized stress exceeding the shear limit of carbon fiber. Furthermore, when the cable undergoes micro-deformation or angular deflection due to temperature changes, wind vibration disturbances, or other disturbances, the elastic ball 15 on the cable can adaptively adjust its position within the spherical groove. The gradually expanding channels prevent sharp stress concentrations at the cable openings, effectively dispersing shear stress, buffering localized stress concentrations, and preventing shear damage to the carbon fiber cable, significantly improving the structural stability and service life of the carbon fiber cable curtain wall.

[0032] Furthermore, the carbon fiber cable mesh provided in this application, through the cooperation of the elastic ball 15 and the ball groove with the gradually expanding channel, can adapt to the slight deformation of the cable and buffer the stress concentration. At the same time, it adopts a detachable splicing clamp structure, which can be assembled after the horizontal and vertical cables are tensioned. It not only adapts to the mechanical properties of carbon fiber cables, but also meets the construction requirements of carbon fiber cable curtain walls, and the overall structure is safe and reliable.

[0033] In some possible implementations, each of the clamping blocks includes a first clamping block 2, a second clamping block 3, a third clamping block 6, and a fourth clamping block 7. The second clamping block 3 and the third clamping block 6 are located between the first clamping block 2 and the fourth clamping block 7, and are arranged sequentially along the length of the first clamping block 2. A transverse groove 13 is formed between the first clamping block 2, the second clamping block 3, and the third clamping block 6, and a longitudinal groove 14 is formed between the second clamping block 3, the third clamping block 6, and the fourth clamping block 7. By defining the clamping blocks as a four-piece combination structure of the first clamping block 2, the second clamping block 3, the third clamping block 6, and the fourth clamping block 7, firstly, through the structural design of the four independent clamping blocks being assembled separately, each clamping block is small in size. Even if the space at the intersection node is narrow after the horizontal and vertical cables are tensioned and shaped, it is easy to complete the assembly and fixing of each block. There is no need to reserve space for the overall cable clamping operation, which completely solves the assembly problem in narrow spaces and has extremely strong adaptability. Furthermore, the second clamping block 3 and the third clamping block 6 are arranged between the first clamping block 2 and the fourth clamping block 7, and are sequentially arranged along the length direction. Through the partitioning and coordination of each clamping block, the transverse groove 13 and the longitudinal groove 14 are precisely partitioned and formed. This modular partitioning structure enables the clamping grooves of the transverse cable 4 and the longitudinal cable 5 to be formed independently without interference. The force partitioning of the cross clamping nodes of the transverse and longitudinal cables is clear, which can effectively avoid mutual compression and interference between the transverse and longitudinal cables when under force, and ensure that the bidirectional cables can independently adapt to deformation. At the same time, the combination and assembly method of the four clamping blocks has a regular structure and high positioning accuracy, which can effectively improve the coaxiality and fit of the transverse and longitudinal grooves, ensure the centering of the cable clamping, and improve the overall clamping accuracy and structural stability of the fixture from the assembly structure.

[0034] In some possible implementations, the first clamping block 2 is provided with a circumferential semi-transverse groove 21, which is a half-groove formed by cutting the transverse groove 13 through the plane containing its axis. The second clamping block 3 and the third clamping block 6 are respectively provided with transverse side grooves 32. The transverse side grooves 32 on the second clamping block 3 and the third clamping block 6 are spliced ​​to form another circumferential semi-transverse groove 21. This circumferential semi-transverse groove 21 and the circumferential semi-transverse groove 21 on the first clamping block 2 are spliced ​​to form a complete transverse groove 13. Through the semi-groove splicing forming process of multi-clamping blocks, a complete transverse groove 13 can be gradually spliced ​​from the side of the cable without inserting the cable. This perfectly adapts to the lateral assembly requirements of the cable node after tensioning, eliminates the need to insert the cable clamps onto the cable in advance, and fully conforms to the construction sequence of tensioning first and then clamping, further improving construction adaptability. Meanwhile, the horizontal groove 13, which is formed by splitting and splicing, can ensure the complete fit between the groove and the cable and the elastic ball 15 on the cable, avoiding the problem of the integrally formed groove not being able to be assembled, and ensuring clamping accuracy.

[0035] In some possible implementations, a semi-transverse ball groove 22 is provided in the middle section of the circumferential semi-transverse groove 21, and a transverse ball groove 31 is provided at the opposite ends of the transverse side grooves 32 on the second clamping block 3 and the third clamping block 6. The transverse ball grooves 31 on the second clamping block 3 and the third clamping block 6 are spliced ​​together to form another semi-transverse ball groove 22. This semi-transverse ball groove 22 is spliced ​​together with the semi-transverse ball groove 22 on the first clamping block 2 to form a complete transverse ball groove.

[0036] After the two semi-transverse ball grooves 22 are spliced ​​together to form a complete transverse ball groove, a transverse conical groove is formed on the side of the transverse side groove 32 away from the transverse ball groove. The two transverse conical grooves are respectively connected to the two ends of the transverse ball groove, together forming the gradually expanding channel of the transverse groove 13. The structural design of the transverse groove 13, "ball groove + double-sided gradually expanding channel", is precisely matched, with high forming accuracy, good structural fit, and ensures stress dispersion effect.

[0037] In some possible implementations, the fourth clamping block 7 has a circumferential semi-longitudinal groove 73, which is a half-groove formed by cutting the longitudinal groove 14 through the plane containing its axis. Both the second clamping block 3 and the third clamping block 6 are provided with longitudinal side grooves 61. The longitudinal side grooves 61 on the second clamping block 3 and the third clamping block 6 are joined together to form another circumferential semi-longitudinal groove 73. This axial semi-longitudinal groove 14 and the circumferential semi-longitudinal groove 73 on the fourth clamping block 7 are joined together to form a complete longitudinal groove 14. The longitudinal groove 14 is formed by splicing the split half-grooves, which is consistent with the forming logic of the transverse groove 13. It also adapts to the construction requirements of lateral assembly and meets the construction sequence of tensioning first and then clamping. Each clamping block cooperates to form the groove, which not only ensures the processing accuracy of the longitudinal groove 14, but also ensures the fit with the longitudinal cable 5 and elastic ball 15 after assembly, ensuring uniform clamping force. At the same time, no installation work is required, and assembly can be completed by lateral splicing only. This further adapts to the assembly work requirements of narrow node space after tensioning and improves the convenience of construction.

[0038] In some possible implementations, a semi-vertical ball groove 74 is provided in the middle section of the circumferential semi-vertical groove, and a vertical side ball groove 62 is provided in the middle of the vertical side grooves on the second clamping block 3 and the third clamping block 6. The vertical side ball grooves 62 on the second clamping block 3 and the third clamping block 6 are spliced ​​together to form another semi-vertical ball groove 74. This semi-vertical ball groove 74 is spliced ​​together with the semi-vertical ball groove 74 on the fourth clamping block 7 to form a complete vertical ball groove. After the two semi-vertical ball grooves 74 are spliced ​​together to form a complete vertical ball groove, a vertical conical groove is formed on the side of the longitudinal side groove 61 away from the vertical ball groove. The two vertical conical grooves are respectively connected to the two ends of the vertical ball groove, which together form the gradually expanding channel of the longitudinal groove 14. The structural design of "ball groove + double-sided gradually expanding channel" of the longitudinal groove 14 is accurately realized, which ensures the forming accuracy of the groove structure, allows the longitudinal cable 5 and the elastic ball 15 to fit evenly with the groove wall, ensures the stress dispersion effect when the longitudinal cable 5 is under force, and avoids shear damage to the cable caused by local stress concentration.

[0039] In some possible implementations, the flexible adaptive clamp for carbon fiber curtain wall cables also includes a rubber pad 12. A glass support plate 72 is provided on the side of the fourth clamping block 7 facing away from the first clamping block 2, and the rubber pad 12 is fitted onto the glass support plate 72. The glass support plate 72 can provide stable load-bearing support for the curtain wall glass, improve the positioning firmness of the glass installation, and prevent the glass from shaking due to being suspended in the air. The rubber pad 12 can play a good role in buffering, shock absorption, and anti-slip protection. On the one hand, it can isolate the rigid metal clamping block from the hard contact with the glass, avoid direct rigid compression between the curtain wall glass and the support plate and clamping block, and effectively prevent the glass from chipping, cracking, and wearing under pressure. On the other hand, it can also buffer the impact load of wind vibration and micro-vibration on the curtain wall, reduce the transmission of structural vibration, and improve the overall seismic performance and service durability of the glass curtain wall.

[0040] In some possible implementations, the flexible adaptive clamp for carbon fiber curtain wall cables further includes a connector, a rubber ring 10, and a glass clamp 11. A connecting claw 71 is provided on the fourth clamping block 7. The connector has a screw and an end cap located at the end of the screw. The screw passes through the glass clamp 11 and connects to the connecting claw 71. The end cap is positioned on the side of the glass clamp 11 opposite to the connecting claw, forming a clamping space between the glass clamp 11 and the connecting claw. The rubber ring 10 is located between the glass clamp 11 and the glass. A rubber sleeve 9 is also fitted onto the connector. Through the interaction of the connecting claw 71 of the fourth clamping block 7, the connector with the end cap, and the glass clamp 11, an assembly structure capable of stably clamping the curtain wall glass is formed. The screw-through connection and end cap positioning assembly ensure reliable structural positioning and convenient assembly and disassembly. The end-limiting structure of the connector effectively prevents the glass clamp 11 from loosening or shifting. Under the long-term wind load and temperature deformation of the curtain wall, it maintains a stable clamping space between the glass clamp 11 and the connecting claw 71, ensuring uniform force and reliable limiting of the glass clamping. This structure achieves integrated operation of the cable clamping structure and the glass connecting fixing structure, eliminating the need for additional fixing accessories, simplifying the curtain wall node construction, and ensuring the flatness and structural stability of the glass installation.

[0041] The rubber ring 10 buffers the rigid contact between the glass and the glass clamp 11, preventing damage to the glass clamping area due to rigid compression. The elasticity of the rubber ring 10 also accommodates minor dimensional errors and installation position deviations in the glass, improving the tolerance of glass installation and further ensuring clamping stability. The rubber sleeve 9 buffers stress at the screw position, preventing stress fatigue of the connector under long-term force, while also isolating the connector from external moisture, reducing the risk of corrosion and improving the overall durability of the structure. Through the cooperation of the connecting claw 71 and the glass clamp 11, the curtain wall glass can be stably clamped and fixed, adapting to the installation needs of glass of different thicknesses. The clamping space can be flexibly adjusted by the screw-in depth of the connector, making it more adaptable.

[0042] Furthermore, the clamp, connecting claw 71 and glass support plate 72 are integrated into one structure. The two claws of the connecting claw 71 are symmetrically distributed and form a 180° angle. The stainless steel glass clamp 11 is connected to the connecting claw 71 by an M16 stainless steel hexagonal screw 1 for fixing the glass panel. The clamping surface is provided with an annular rubber ring 10, and the M16 stainless steel hexagonal screw 1 is fitted with a rubber sleeve 9 hole.

[0043] In some possible implementations, the flexible adaptive clamp for carbon fiber curtain wall cables also includes a rubber sheet 8, which is attached to the side of the fourth clamp 7 opposite to the first clamp 2.

[0044] A rubber sheet 8 is attached to the side of the fourth clamping block 7 opposite to the first clamping block 2, forming a flexible buffer layer between the clamping block, the glass clamp 11, and the curtain wall glass structure. The rubber sheet 8 effectively compensates for processing errors on the contact surface of the metal clamping block, eliminates assembly gaps, and avoids local stress concentration and friction noise caused by loose contact surfaces of hard metals. At the same time, the rubber sheet 8 has excellent vibration damping, noise reduction, and anti-slip properties, which can further weaken the transmission of curtain wall vibration, reduce structural friction and wear, prevent long-term friction of the metal clamping block from causing glass damage, further improve the protective effect and operational stability of the curtain wall nodes, and extend the overall service life of the curtain wall.

[0045] In some possible implementations, the gradually expanding channel is a conical hole with a cone angle of 10° to 12°. Limiting the gradually expanding channel to a conical hole structure with a cone angle of 10° to 12° represents the optimal cone angle range for adapting to the deformation and stress dispersion of the carbon fiber cable. A cone angle that is too small will result in a weak gradual transition effect of the channel, failing to effectively release shear stress and making it difficult to avoid stress concentration damage to the carbon fiber cable; a cone angle that is too large will reduce the clamping coverage area of ​​the cable by the groove, weakening clamping stability and making the cable prone to loosening and displacement. This invention limits the cone angle to 10° to 12°, which, while ensuring sufficient clamping coverage force and stable clamping of the carbon fiber cable, maximizes the stress dispersion effect of the gradual transition of the conical hole, perfectly adapting to the shear-weak material characteristics of the carbon fiber cable, balancing clamping reliability and flexible adaptive protection performance, and significantly improving the adaptability and practicality of the clamp.

[0046] Example 2 See Figures 1-5 As shown, this disclosure provides a carbon fiber cable mesh, including a plurality of transverse cables 4, a plurality of longitudinal cables 5, and a flexible adaptive clamp for carbon fiber curtain wall cables as described in Embodiment 1. The transverse cables 4 and longitudinal cables 5 are staggered to form a mesh structure. Multiple elastic balls 15 are provided on each of the transverse cables 4 and longitudinal cables 5, with each elastic ball 15 on the transverse cables 4 and longitudinal cables 5 facing each other. Each clamp is fitted onto the intersection of the transverse cables 4 and longitudinal cables 5. A transverse groove 13 is fitted onto one of the transverse cables 4, and a longitudinal groove 14 is fitted onto one of the longitudinal cables 5. Of the two opposing elastic balls 15, one is embedded in the groove of the transverse groove 13, and the other is embedded in the groove of the vertical groove.

[0047] The carbon fiber cable net provided in this embodiment, based on the aforementioned flexible adaptive clamp and matching assembly structure of carbon fiber cables and elastic spheres 15, breaks through the traditional rigid cable clamp's forced constraint clamping paradigm through the synergistic effect of the elastic sphere 15-shaped nodes and the gradually expanding channels of the clamp. It optimizes the traditional single rigid constraint structure into a flexible force-bearing system of "energy dissipation + adaptive guidance", effectively solving the technical defects of traditional carbon fiber cable net nodes such as stress concentration, poor micro-motion adaptability, severe shear damage accumulation, and weak structural energy dissipation and vibration reduction capabilities. It has the following significant beneficial effects.

[0048] This cable mesh features a pair of matching elastic spheres 15 on the transverse cables 4 and longitudinal cables 5. These elastic spheres 15 are embedded within the spherical grooves of the transverse groove 13 and longitudinal groove 14 of the clamp, forming a linkage with the grooves and the double-sided gradually expanding channels. When the carbon fiber cable mesh undergoes axial micro-deformation under temperature changes and wind-induced vibration loads, the radial elastic deformation of the elastic sphere 15 nodes is automatically triggered. Simultaneously, the spherical nodes can achieve slight adaptive rotation around their center using the groove structure. Combined with the smooth, gradual structure of the gradually expanding channels, this causes the cables to undergo controllable and moderate radial displacement along the inner wall of the channels. This linkage mechanism completely overcomes the shortcomings of traditional rigid clamps that lock cable displacement and prevent stress release, achieving radial flexible release of clamping force and adaptive compensation for axial cable deformation.

[0049] On the one hand, this structure gradually dissipates the excess load generated by axial micro-motion and vibration displacement during the service of the cable through the deformation of the elastic ball 15, the micro-rotation of the ball center, and the controllable radial displacement. This avoids the continuous accumulation of vibration load and deformation stress at the cable intersection, significantly reducing the shear stress and compressive stress at the node. It fundamentally avoids the problems of fiber slippage, interlayer peeling, and local shear failure in carbon fiber cables due to stress concentration and cyclic shear action. It precisely adapts to the low shear strength and stress sensitivity of carbon fiber cables, greatly improving the overall damage resistance and service life of the carbon fiber cable net.

[0050] On the other hand, the synergistic adaptation structure of the elastic sphere 15 and the gradually expanding channel enables flexible adaptation and adjustment of the multi-dimensional deformation of the cables. Compared with the shortcomings of traditional rigid nodes, which can only achieve fixed clamping and cannot adapt to minute deformations, this cable mesh can adaptively offset the internal stress caused by temperature difference deformation and wind vibration reciprocating displacement, ensuring that the horizontal and vertical cable mesh is always in a uniform stress state. This avoids problems such as local cable overload, uneven stress leading to mesh deformation, and failure of curtain wall flatness, effectively ensuring the accuracy, stability and overall stiffness uniformity of the carbon fiber cable mesh structure.

[0051] Meanwhile, relying on the combination of split clamps and 15 elastic ball nodes, this carbon fiber cable net can perfectly adapt to the special construction process of carbon fiber curtain walls, which involves tensioning first and then clamping. Each clamp block can be assembled separately and precisely aligned with the 15 elastic ball positioning assembly. Efficient installation can be completed within the narrow node space after tensioning, making construction highly convenient. Moreover, the formed cable net nodes have both clamping stability and flexible self-adaptive capabilities, ensuring the positioning accuracy of the cable intersection nodes while retaining the stress release and energy dissipation buffer performance of the structure. This significantly improves the overall structure of the carbon fiber curtain wall's resistance to wind vibration and temperature difference deformation, and significantly enhances the safety, stability, and environmental adaptability of the building curtain wall.

[0052] In summary, this carbon fiber cable mesh innovatively achieves flexible clamping, adaptive compensation, and dynamic energy dissipation of carbon fiber cable mesh nodes through the collaborative construction of 15 elastic ball nodes and flexible clamps with ball grooves and gradually expanding channels. It solves the pain points of traditional rigid nodes, such as poor adaptability, severe stress concentration, and easy damage to carbon fiber cables. It fully leverages the structural advantages of lightweight and high strength of carbon fiber materials and has excellent engineering application value and promotion prospects.

[0053] In some possible implementations, the elastic ball 15 includes two hemispheres 151 connected by a glue, and the two hemispheres 151 are fitted onto the transverse cable 4 or the longitudinal cable 5.

[0054] An elastic spherical 15-shaped node is installed at the connection between the cable and the clamp. The spherical node bears the radial compressive stress caused by the clamp fastening, avoiding rigid contact between the cable and the metal surface of the clamp and preventing stress concentration on the cable. The spherical node consists of two hemispherical nodes, which are bonded to the cable surface with structural adhesive and form a continuous elastic interface layer after curing. The diameter of the spherical node is determined according to the engineering requirements.

[0055] The elastic ball 15 is optimized into a split-type assembly structure consisting of two hemispheres 151 bonded together with adhesive. The two hemispheres can be directly fitted onto the outside of the transverse cable 4 and the longitudinal cable 5, eliminating the need for the end-entry and forced-fit assembly method required for the integral elastic ball 15. This design is specifically adapted to the material characteristics of carbon fiber cables, which are susceptible to bending, abrasion, and surface damage. The split-type hemispherical assembly structure eliminates the need to disassemble the cable net or thread it through the cable ends. It allows for direct on-site alignment and enclosing at any node of the transverse and longitudinal cables, significantly reducing the installation difficulty of the elastic ball 15. It is compatible with on-site assembly of pre-formed cable meshes, effectively improving the assembly efficiency and construction error tolerance of the overall cable net. Simultaneously, it completely avoids the problems of scratching, squeezing, and abrasion of the carbon fiber cable surface fibers during the traditional integral ball fitting process, comprehensively protecting the structural integrity of the carbon fiber cable. Meanwhile, the connection method of fixing the two hemispheres 151 with adhesive ensures that the two hemispheres are tightly joined and have strong integrity after being enclosed. The formed complete elastic sphere 15 has a regular surface and uniform roundness, which can achieve full-circumferential precise fitting and embedding with the ball groove inside the clamp, ensuring the node limiting accuracy and uniform force distribution. The adhesive connection has excellent flexible bonding and micro-deformation adaptation characteristics. Compared with rigid buckle and bolt fastening structures, it can adapt to the micro-adaptive fitting of the hemispheres 151, make up for the small gaps in the assembly, and prevent the two hemispheres from loosening, misaligning, or cracking under stress. At the same time, the adhesive can also play the role of internal buffer, shock absorption, and anti-seepage. Under the long-term reciprocating deformation of the cable and the vibration of the node, it can continuously maintain the overall structural stability of the elastic sphere 15, ensuring that the elastic sphere 15 always has stable elastic energy storage, vibration absorption, and stress release capabilities. In addition, the split structure facilitates the partial replacement and maintenance of individual elastic spheres 15 in the later stage. When individual node elastic components age or fail, the corresponding hemisphere 151 and colloid can be disassembled and replaced separately without replacing the entire cable or disassembling a large number of clamps. This greatly reduces the later operation and maintenance costs and inspection difficulty of the curtain wall, and effectively ensures the node buffering performance and structural stability of the carbon fiber cable net throughout its entire life cycle.

[0056] In some possible implementations, the elastic ball 15 is a rubber elastic ball 15. Rubber material has excellent elasticity, low cost, and is easy to mold. It also has good weather resistance and fatigue resistance, and can withstand reciprocating deformation for a long time without aging and cracking. It is suitable for the service requirements of long-term micro-deformation of curtain wall nodes, ensuring the long-term stability of the elastic ball 15.

[0057] Example 3 Based on Examples 1 and 2, the installation steps of the carbon fiber cable net include: S1: Erection of horizontal and vertical cables and overall tensioning and shaping Before construction, the appearance and performance of the transverse and longitudinal carbon fiber cables used in the construction are inspected, and cable components with damage, fiber peeling, or deformation defects are removed. Several transverse cables 4 and longitudinal cables 5 are staggered and erected to initially form the curtain wall grid. Unlike the traditional steel cable curtain wall construction process, this structure requires the completion of the graded tensioning of all longitudinal cables 5 and transverse cables 4 first. The tensioning and shaping are carried out strictly according to the design tension stress to ensure that the transverse and longitudinal cables reach the preset stress state and grid size accuracy. Only after all cables are tensioned and the structural shape is stable can the clamp installation process begin, avoiding compression and shear damage to the carbon fiber cables during the tensioning process.

[0058] S2: 15 elastic balls are deployed. According to the grid size of the curtain wall design, elastic balls 15 are fixedly installed at the preset intersection positions of each horizontal cable 4 and vertical cable 5 to ensure that the positions of the elastic balls 15 on the horizontal cable 4 and the vertical cable 5 correspond one-to-one and are accurately aligned, thus ensuring the accuracy of subsequent node assembly.

[0059] S3: Pre-assembly check and fitting inspection of fixture components Organize the matching detachable clamping block assembly, check the structural integrity of the transverse groove 13 and longitudinal groove 14 of each clamping block, confirm that the ball groove inside the groove and the gradually expanding channels on both sides are smooth and without defects, ensure that the gradual structure of the channel and the size of the ball groove are precisely matched with the specifications of the carbon fiber cable and the elastic ball 15, clean the impurities on the contact surface of the clamping block, and prepare for separate assembly.

[0060] S4: Cross-node split-type clamping block assembly and positioning For the cross-nodes of horizontal and vertical cables where the working space is limited after tensioning and shaping, a modular assembly method using clamp blocks is adopted for construction. Each clamp block is sequentially fitted and fitted onto the intersection of the horizontal cable 4 and the vertical cable 5, so that the horizontal groove 13 of the clamp block is aligned with the horizontal cable 4 and the vertical groove 14 is aligned with the vertical cable 5. The position of the clamp block is precisely adjusted so that the corresponding elastic balls 15 on the horizontal cable 4 and the vertical cable 5 are embedded into the ball grooves of the horizontal groove 13 and the vertical groove 14, respectively, achieving a precise fit and match between the elastic balls 15 and the ball grooves.

[0061] S5: Clamping block locking and fixing, forming node structure After all clamping blocks are aligned, the elastic ball 15 is fully embedded in the ball groove, and the cable is attached to the inner wall of the gradually expanding channel, all the separate clamping blocks are detachably locked together to ensure that the connection of each clamping block is firm and without loose gaps. After assembly, the transverse groove 13 and the longitudinal groove 14 completely cover the transverse cable 4 and the longitudinal cable 5 at the corresponding positions, forming a flexible clamping node based on the ball groove and the gradually expanding channel structure, thus completing the assembly operation of a single intersection node.

[0062] S6: Full network point-of-sale cyclic assembly molding Following the above node assembly process, all horizontal and vertical cable intersection nodes of the carbon fiber cable net are sequentially assembled, positioned, fitted, and locked to complete the node assembly of the entire carbon fiber cable net, forming a complete carbon fiber flexible adaptive cable net structure.

[0063] S7: Overall Verification and Acceptance Testing After all nodes are assembled, a comprehensive inspection and verification is conducted on the flatness of the overall cable mesh, the cable tension, and the clamping and securing status of each fixture node. It is checked that the elastic ball 15 of each node is properly fitted into the groove, and that the cables and gradually expanding channels are evenly aligned, with no local compression, misalignment, or other issues. This ensures that the cable mesh possesses axial micro-motion adaptive compensation and radial stress release capabilities, meeting the stress and deformation adaptation requirements of the curtain wall during service. After acceptance, the overall installation is completed.

[0064] In some possible implementations, step S6 further includes the step: S6.1: Install and tighten the lateral clamps first. First, assemble the second clamping block 3 and the third clamping block 6, and precisely fit the two sets of clamping blocks into the preset assembly position of the intersection node of the horizontal and vertical cables. Then, use M16 stainless steel internal hexagonal screws 1 to fasten the second clamping block 3 and the third clamping block 6 to complete the fixed positioning of the lateral base clamping block, and provide a reference structure for subsequent hole forming.

[0065] S6.2: Assemble the top side clamp and pre-tighten it. After the second clamping block 3 and the third clamping block 6 are installed in place, the first clamping block 2 and the fourth clamping block 7 are assembled in sequence to ensure that each clamping block fits and is aligned without offset or misalignment. After alignment, the first clamping block 2 and the fourth clamping block 7 are pre-tightened with M16 stainless steel internal hex screws to ensure that each set of clamping blocks fits tightly and the assembly gap is uniform.

[0066] S6.3: Forming a composite channel structure with horizontal and vertical pores After assembly, the first clamping block 2, the second clamping block 3, and the third clamping block 6 together form a transversely expanding channel and matching ball groove structure adapted to the transverse cable 4, completely covering the transverse carbon fiber cable; at the same time, the second clamping block 3, the third clamping block 6, and the fourth clamping block 7 together form a vertically expanding channel and matching ball groove structure adapted to the longitudinal cable 5, completely covering the longitudinal carbon fiber cable, ensuring that the transverse and vertical cables are precisely fitted with the corresponding channels and ball grooves respectively, and the elastic ball 15 is completely embedded in the corresponding ball groove, forming a flexible adaptive clamping node.

[0067] S6.4: Full-mesh node cyclic assembly molding Following the unified process of the above sub-steps, the clamping block assembly, screw fastening, and hole forming operations are completed one by one for all horizontal and vertical cable intersection nodes of the cable net to ensure that the assembly process and forming structure of all nodes are consistent, and finally a complete carbon fiber flexible adaptive cable net structure with uniform overall stress and adaptive deformation and stress release functions is formed.

[0068] Following the above node assembly process, all horizontal and vertical cable intersection nodes of the carbon fiber cable net are sequentially assembled, positioned, fitted, and locked to complete the node assembly of the entire carbon fiber cable net, forming a complete carbon fiber flexible adaptive cable net structure.
