Abstract
Description
Technical Field
[0001] This invention relates to the technical field of grid curtain walls, specifically to a large-angle universal ball hinge grid curtain wall and its construction method. Background Technology
[0002] As modern architectural designs become increasingly complex and artistic, cable-stayed grid curtain walls, with their lightweight, transparent, and flexible design, have been widely adopted in large public buildings, commercial complexes, and sports stadiums. These curtain walls typically combine a prestressed cable system with decorative grid panels, requiring both structural safety and stability while achieving precise aesthetic control and visual continuity. Particularly in areas with large angles or curved surfaces, the positioning and angle adjustment of the grid panels become critical challenges in design and construction. Traditional cable-stayed grid curtain walls often use fixed clamps or simple hinges for connection nodes, making it difficult to fine-tune the grid in multiple directions. This can easily lead to accumulated installation errors, uneven facades, and poor adaptability to dynamic loads and temperature deformation, affecting the overall performance and service life of the curtain wall. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, a large-angle universal ball hinge grille curtain wall is provided to solve the problem that the connection nodes of traditional cable-stayed grille curtain walls are difficult to fine-tune the grille in multiple directions.
[0004] To achieve the above objectives, a large-angle universal ball-hinge grille curtain wall is provided, comprising: Multiple cables are provided, with their upper and lower ends respectively installed on the steeply inclined exterior facade of the building structure. The multiple cables are spaced apart along the circumferential direction of the building structure, and multiple spherical cable clamps are spaced apart on the cables. A ball joint clamp includes two clamping plates, each clamping plate having a through hole. The two clamping plates are disposed on opposite sides of a spherical cable clamp, and the opposite sides of the spherical cable clamp are rotatably inserted into the through hole. A tie member is connected between the two clamping plates. The grid is mounted on ball joint clamps corresponding to the positions of the multiple cables.
[0005] Furthermore, a crossbar is installed on the upper part of the steeply inclined facade, and multiple through holes are opened in the crossbar. The through holes are arranged along the inclination direction of the steeply inclined facade. An upper cable sleeve is connected to the upper end of the cable, and the upper cable sleeve is installed in the through holes in an adjustable position.
[0006] Furthermore, a partition is formed in the through hole, and the partition has a guide hole. The upper cable sleeve is connected to a first screw, which is movably inserted into the guide hole. The first screw is screwed with a threaded engagement member, which abuts against the partition.
[0007] Furthermore, a base plate is installed on the lower part of the steeply inclined facade, and two opposing ear plates are formed on the outer side of the base plate. The lower end of the cable is rotatably mounted on the two ear plates via a hinge shaft.
[0008] Furthermore, the lower end of the cable is connected to a lower cable sleeve, and the lower cable sleeve is connected to a telescopic component with adjustable length. The end of the telescopic component away from the telescopic cable is connected to the hinge shaft.
[0009] Furthermore, the telescopic component includes: Two second screws are coaxially arranged, one second screw is connected to the lower cable sleeve, and the other second screw is connected to the hinge shaft; A threaded sleeve, the two ends of which are respectively screwed into two second screws.
[0010] Furthermore, the two clamping plates extend towards each other at opposite ends to form abutment plates, and the abutment plates at one end of the two clamping plates abut against each other.
[0011] Furthermore, the grid includes two grid strips, which are respectively disposed on opposite sides of the ball joint clamp. The upper and lower sides of the opposite surfaces of the two grid strips are respectively extended to form flanges. The flanges are formed with notches, and the cable is movably disposed in the notches. The flanges on one side of the two grid strips overlap and are connected to the ball joint clamp.
[0012] Furthermore, the top and bottom of the two clamping plates extend in opposite directions to form support plates, and the flange plate is detachably mounted on the support plates.
[0013] This invention provides a construction method for a large-angle universal ball-hinge grille curtain wall, comprising the following steps: Multiple spherical cable clips are installed at intervals on the cable, such that the spacing between two adjacent spherical cable clips is adapted to the spacing of the grid. The two clamping plates of the ball hinge clamp are set on opposite sides of the spherical cable clamp, and the opposite sides of the spherical cable clamp are rotatably inserted into the through hole and connected to the two clamping plates by a tie member; The upper and lower ends of multiple cables are respectively installed on the steeply inclined exterior facade of the building structure, so that the multiple cables are spaced apart along the circumferential direction of the building structure; Adjust the pitch and deflection angles of the ball joint clamps corresponding to the positions on the multiple cables, and install the grid onto the ball joint clamps corresponding to the positions on the multiple cables.
[0014] The beneficial effect of the present invention is that the large-angle universal ball-hinged grid curtain wall of the present invention uses a "ball-hinged clamp" as the connection hub between the grid and the cable, realizing independent and stepless precise adjustment of the grid bars in the up and down and left and right (i.e. pitch and deflection) directions, which is the core to meet the precise positioning of complex facade shapes.
[0015] The node design of the large-angle universal spherical hinge grid curtain wall of the present invention comprehensively considers dynamic load adaptability. The spherical hinge clamp itself provides rotational buffer, and together with the clamping of the "spherical cable clamp" and the flexible contact with the cable, it forms a flexible connection system that can effectively release local bending moment, reduce stress concentration, and improve the fatigue life of the node.

Each spherical cable clamp includes a pair of clamping blocks. The clamping blocks are hemispherical. Through grooves are formed on the opposite sides of the pair of clamping blocks. The through grooves of the pair of clamping blocks enclose a channel. The cable passes through the channel. (See reference...) Figure 5 As shown, the two clamping blocks are detachably connected together by bolts to form a complete sphere.
[0029] The ball joint clamp 2 includes a clamping plate 21 and a connecting member 22. (Continue reading...) Figure 5 As shown, there are two clamping plates. The two clamping plates are arranged opposite each other. Each clamping plate 21 has a through hole 210. The diameter of the through hole is smaller than the diameter of the spherical cable clamp. The two clamping plates 21 are located on opposite sides of the spherical cable clamp 11. The opposite sides of the spherical cable clamp 11 are rotatably inserted into the through hole 210. One side of the spherical cable clamp extends into the through hole, and can even extend to the outside of the clamping plate. A tie member 22 connects the two clamping plates 21. The spherical cable clamp and the clamping plates can rotate relative to each other, that is, when the spherical cable clamp and the cable are fixed, the spherical hinge clamp can rotate in the up-down direction (pitch) and the left-right direction (yaw).
[0030] The grille 3 is installed along the circumferential direction of the building structure. There are multiple grilles. The multiple grilles are spaced apart along the inclination direction of the steeply inclined facade. The grilles 3 are installed on the ball joints 2 corresponding to the positions of the multiple cables 1. Each grille is installed on multiple ball joints in the horizontal direction.
[0031] Combination Figure 2 and Figure 3 As shown, a crossbar 41 is installed on the upper part of the steeply inclined facade. In this embodiment, an upper ring beam is formed on the upper part of the building structure. A crossbar 41 is installed on the outer side of the upper ring beam. Multiple through holes are provided in the crossbar 41. The through holes are arranged along the inclination direction of the steeply inclined facade. An upper cable sleeve 12 is connected to the upper end of the cable 1. The upper cable sleeve 12 is installed in the through holes in an adjustable position.
[0032] Preferably, the lower end of the cable is connected to a lower cable sleeve. One end of the upper cable sleeve is fitted onto the upper end of the cable. The upper end of the cable is embedded in the upper cable sleeve. The lower end of the cable is embedded in one end of the lower cable sleeve.
[0033] A partition 42 is formed in the through hole. The partition is arranged radially along the through hole. The partition 42 has a guide hole. A first screw 13 is connected to the upper cable sleeve. The first screw is coaxially connected to the other end of the upper cable sleeve. The first screw 13 is movably inserted into the guide hole. A threaded engagement member 14 is screwed onto the first screw 13. The threaded engagement member 14 abuts against the partition 42.
[0034] When adjusting the tension of the cable, the position of the screw assembly on the first screw can be adjusted.
[0035] Combination Figure 2 and Figure 4 As shown, a base plate 15 is mounted on the lower part of the steeply angled facade. Two opposing lug plates 16 are formed on the outer side of the base plate 15. The lower end of the cable 1 is rotatably mounted to the two lug plates 16 via a hinge shaft 17.
[0036] In this embodiment, a lower ring beam is formed at the bottom of the building structure. An embedded plate is embedded in the lower ring beam. A base plate is welded to the outside of the embedded plate. Ear plates are vertically arranged. A hinge shaft is connected to the lower end of the cable. Axle holes are formed in the ear plates. Both ends of the hinge shaft are rotatably inserted into the axle holes of the two ear plates.
[0037] The lower end of the cable 1 is connected to one end of the lower cable sleeve 20. The lower cable sleeve 20 is connected to a length-adjustable telescopic component. The lower cable sleeve is connected to the hinge shaft via the telescopic component. Specifically, the end of the telescopic component furthest from the telescopic cable 1 is connected to the hinge shaft 17.
[0038] The telescopic assembly includes two second screws 18 and a threaded sleeve 19. The two second screws 18 are coaxially arranged. One second screw 18 is connected to the lower cable sleeve 20. The other second screw 18 is connected to the hinge shaft 17. Both ends of the threaded sleeve 19 are screwed onto the two second screws 18 respectively.
[0039] When adjusting the tension of the cable for tension control and shape finding, the tension of the cable can also be adjusted by adjusting the depth of the two second screws inserted into the threaded sleeve.
[0040] Combination Figure 5 and Figure 6 As shown, each clamp is elongated. Support plates 211 extend from opposite ends of the two clamps 21. The support plates 211 at one end of the two clamps 21 abut against each other. The two clamps and the support plates together form a bottomless and lidless box structure. The spherical cable can rotate within this box structure.
[0041] See Figure 6 and Figure 7 As shown, the grille 3 includes two grille bars 31. The two grille bars 31 are respectively disposed on opposite sides of the ball joint clamp 2. Flange plates 32 extend from the upper and lower sides of the opposite surfaces of the two grille bars 31, respectively. The flange plates 32 have notches. The cable 1 is movably disposed in the notches. The flange plates 32 on one side of the two grille bars 31 overlap and are connected to the ball joint clamp 2.
[0042] Continue reading Figure 5 , Figure 6 and Figure 7 The top and bottom of the two clamping plates 21 extend in opposite directions to form support plates 212. The flange plate 32 is detachably mounted on the support plate 212.
[0043] In this embodiment, a light groove is formed on the outer side of the grille strip that is furthest from the building structure. A light strip is installed in the light groove.
[0044] This invention provides a construction method for a large-angle universal ball-hinge grille curtain wall, comprising the following steps: S1. Multiple spherical cable clips 11 are installed at intervals on the cable 1, so that the spacing between two adjacent spherical cable clips 11 is adapted to the spacing of the grid.
[0045] S2. The two clamping plates 21 of the ball hinge clamp 2 are set on opposite sides of the spherical cable clamp 11. The opposite sides of the spherical cable clamp 11 are rotatably inserted into the through hole 210 and connected to the tie member 22 between the two clamping plates 21.
[0046] S3. Install the upper and lower ends of the multiple cables 1 onto the steeply inclined exterior facade of the building structure 4 respectively, so that the multiple cables 1 are spaced apart along the circumferential direction of the building structure 4.
[0047] First, the upper and lower ring beams are precisely measured and laid out according to the design drawings. The lower embedded plate, base plate and ear plate are installed. At the same time, the upper cable fixing device is installed in the corresponding position inside the crossbar on the upper ring beam.
[0048] The cables were erected, and the initial tension and length adjustment were carried out using the adjustment components at both ends. A cable force gauge and a total station were used for dual-control measurement to ensure that the shape of the cable net was consistent with the design.
[0049] S4. Adjust the pitch and deflection angles of the ball joint clamps 2 corresponding to the positions on the multiple cables 1, and install the grid onto the ball joint clamps 2 corresponding to the positions on the multiple cables 1.
[0050] The ball joint clamps are used to make fine adjustments to the three-dimensional angles (pitch angle and deflection angle) of each grid unit, and three-dimensional laser scanning technology is used to verify the overall curtain wall surface to ensure accurate shape and no visual abrupt changes.
[0051] Finally, tighten all the connecting bolts of the ball joint clamps to the specified torque, and take anti-loosening measures if necessary to complete the final fixing and form a curtain wall system with stable structure, reliable force transmission and precise shape.
[0052] The large-angle universal spherical hinge grille curtain wall of this invention uses a pre-embedded plate at the lower ring beam of the building structure. A base plate is welded to the pre-embedded plate, and ear plates are welded to the base plate to fix the ends of the cables. A cable fixing device is installed inside the crossbars of the upper ring beam. Adjustable components are provided at both ends of the cables, allowing for fine-tuning of the cable length, facilitating tensioning and shape matching. Spherical cable clamps are installed on the cables, and the grille strips are connected to the cable structure via spherical hinge clamps, forming a stable and reliable support system. The spherical hinge clamps have multi-directional rotation adjustment capabilities, allowing for precise adjustment of the grille strips' vertical and horizontal angles, thereby effectively controlling the styling effect and visual continuity of the curtain wall facade and significantly improving its aesthetic appeal.
[0053] The large-angle universal ball-hinged grille curtain wall of this invention achieves precise and independent adjustment of the spatial angle of the grille strips by setting a ball-hinged clamp with multi-directional rotation adjustment function; combined with the hinge design, it improves the adaptability and long-term stability of the nodes under dynamic loads; and relying on the adjustment components at the ends of the cables and the standardized connection system, it significantly improves construction efficiency, control accuracy and overall visual effect of the curtain wall, thereby systematically solving the comprehensive problems of complex-shaped curtain walls in terms of structural reliability, installation accuracy and aesthetic performance.
[0054] The large-angle universal ball hinge grid curtain wall of the present invention aims to solve problems such as reliable connection, multi-directional angle adjustment and visual continuity at the junction of the cable and the grid strip under large-angle or complex curved surface conditions.
[0055] The large-angle universal ball-hinge grille curtain wall of the present invention is mainly composed of the following core components: (1) Anchoring components.
[0056] An embedded plate is installed at the lower ring beam as the main load-bearing foundation. The base plate is welded and fixed to the embedded plate, and ear plates are welded to form the anchor points at the lower end of the cable. In the upper ring beam area, a cable fixing device is integrated inside the crossbar to form a complete closed-loop force transmission path, ensuring the stability of the cable system boundary and clear force transmission.
[0057] (2) Cable and length adjustment component.
[0058] The cables are made of high-strength stainless steel or galvanized steel, and are equipped with special adjustment components at both ends, which can realize on-site fine adjustment of the cable length, facilitate tension control and shape finding, and ensure that the prestress distribution of the cable net is uniform and the overall line shape meets the design intention.
[0059] (3) Spherical cable clamp and spherical hinge clamp A spherical cable clamp is installed on the cable, with the inner arc surface of the through groove fitting against the cable, and is tightened by bolts to achieve a secure grip. The grid strip is connected to the spherical cable clamp via a ball joint clamp, which has a multi-directional rotation adjustment function, allowing for independent and continuous fine-tuning in multiple directions such as up and down, left and right, thereby achieving precise control of the spatial posture of the grid strip.
[0060] (4) Grille strip connection and finishing system The grille strips are fixed to the support plate of the ball joint clamp using bolts or special clips, and the angle can be corrected using the ball joint clamp after installation. This design ensures that the grille strips maintain a flat and continuous visual appearance at any tilt angle, effectively improving the overall integrity and aesthetics of the curtain wall facade.
[0061] The large-angle universal ball-hinged grille curtain wall of this invention uses a "ball-hinged clamp" as the connection hub between the grille and the cable, realizing independent and stepless precise adjustment of the grille bars in the up and down and left and right (i.e. pitch and deflection) directions. This is the core of meeting the precise positioning of complex facade shapes.
[0062] The node design of the large-angle universal spherical hinge grid curtain wall of the present invention comprehensively considers dynamic load adaptability. The spherical hinge clamp itself provides rotational buffer, and together with the clamping of the "spherical cable clamp" and the flexible contact with the cable, it forms a flexible connection system that can effectively release local bending moment, reduce stress concentration, and improve the fatigue life of the node.
[0063] The large-angle universal ball hinge grid curtain wall of the present invention has a dual guarantee of construction controllability. On the one hand, by setting "adjustment components" at both ends of the cable, the length and tension of the cable body can be conveniently fine-tuned on site, ensuring the precise control of the overall shape of the cable net and the prestress. On the other hand, the standardized "embedded plate-base plate-ear plate" anchoring system and modular clamp connection make the installation process efficient and controllable, greatly improving the construction quality and consistency.
[0064] Compared to the traditional construction methods of large-angle curtain wall nodes, which involve on-site cutting, point-by-point welding, and repeated manual adjustments, the large-angle universal ball-hinge grille curtain wall of this invention utilizes modular and standardized node construction and prefabricated construction methods. Through prefabricated substrates, cable-stayed structural components, and universal ball-hinge clamping systems, it significantly reduces on-site welding, positioning, and debugging workload, shortening the construction cycle. Batch processing of standardized components improves material utilization, while precise angle adjustment greatly enhances the first-time installation pass rate, effectively reducing material waste and rework costs. Based on a typical large-scale project, this technology can shorten the critical path duration by approximately 15-20 days, save approximately 250,000 RMB in labor and management costs, and reduce material waste by approximately 100,000 RMB. Its lightweight design and convenient installation method reduce reliance on long-term occupation of large hoisting equipment, and are expected to save approximately 150,000 RMB in machinery operating costs. In summary, this technology can save a single large-scale project approximately 500,000 RMB in total costs, significantly improving the project's economic efficiency and return on investment.
[0065] The large-angle universal ball hinge grille curtain wall of the present invention creates extensive social value by providing a reliable and efficient large-angle curtain wall solution.
[0066] First, its efficient installation process can shorten the construction cycle of public buildings such as stadiums and transportation hubs, enabling projects to be put into operation more quickly, serve the public in advance, and generate social benefits.
[0067] Secondly, this technology reduces high-risk operations such as high-altitude welding on site, thereby lowering construction safety risks. Its prefabricated dry construction also reduces noise and dust pollution, meeting the requirements of green construction and safe production.
[0068] More importantly, the large-angle universal spherical hinge grille curtain wall system of this invention systematically solves the industry pain points of difficulty in controlling the precision of complex curtain wall shapes and poor visual effects, thus improving the aesthetic quality of urban buildings and the visual experience of public spaces. The widespread application of the large-angle universal spherical hinge grille curtain wall of this invention not only enhances the technological competitiveness and brand influence of enterprises in the high-end curtain wall field, but also provides a practical and feasible technical path for promoting the upgrading of the construction industry towards industrialization, refinement, and high performance, playing a positive demonstrative and leading role in the industry.
[0069] In the construction of the large-angle universal ball hinge grille curtain wall of this invention, in order to ensure that the system performance is consistent with the design goals, the following key aspects must be strictly controlled: The first step is the positioning and welding of the pre-embedded and transition systems. This requires precise layout using a total station and welding and testing according to the secondary weld standard to ensure reliable anchoring.
[0070] Secondly, the coordinated control of cable tension and shape should be adopted. A graded synchronous tensioning process should be used, and dual control monitoring should be carried out using a cable force gauge and a total station to ensure uniform cable force and smooth alignment.
[0071] The most critical aspect is the spatial adjustment and final locking of the ball joint clamp. After finely adjusting the posture of each grid unit using its multi-directional function, all locking bolts must be tightened with a uniform torque to prevent loosening later.
[0072] In addition, attention must be paid to the dynamic compatibility and fatigue details of the joints to ensure that the ball joints have adequate rotational capacity under design loads. Anti-loosening measures should be implemented at bolted connections, and contact surfaces should be smoothed to improve fatigue resistance under long-term dynamic loads. Through these refined control measures, installation efficiency and styling accuracy are improved while comprehensively ensuring the structural safety, dynamic adaptability, and durability of the joints.
[0073] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
