An adjustable large-span space grid seismic rotation support device

Abstract

The present invention relates to an adjustable, seismic-resistant rotating bearing device for a large-span space truss, which solves the problems of bearing installation accuracy and seismic resistance in the prior art. The device comprises embedded steel plates, stiffening steel plates, steel round tubes, rubber pads, positioning plates, bearing uprights, and bearing balls. Horizontal errors are resolved by adjusting the position of the stiffening steel plates on the embedded steel plates, vertical errors are compensated by adjusting the height of the steel round tubes, and angular errors are accommodated by rotating the bearing balls. The rubber pads are arranged between the bearing ribs and the positioning plates, and absorb vibrations by elasticity, thereby enhancing seismic resistance.

Furthermore, the bearing fine-tuning design facilitates fine-tuning during installation. The present invention has strong adaptability and high precision, and is widely applicable to the installation of support nodes for large-span space trusses, improving structural stability and safety, and having outstanding seismic resistance advantages.

Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant building structures, and in particular to an adjustable large-span space grid earthquake-resistant rotating support device. Background Art

[0002] With the continuous development of modern architecture and large-scale industrial facilities, long-span steel grid structures have been widely used in large-span buildings such as stadiums, exhibition halls, and airport terminals due to their elegant appearance and efficient structural characteristics. Large-span spatial grid structures typically consist of grid balls, bearings, steel pipes, and other components. The bearings serve as the connection between the grid structure and the underlying concrete structure, and their stability and accuracy have a significant impact on the safety and seismic performance of the entire structure.

[0003] However, during the construction of long-span trusses, vertical and horizontal errors often occur due to issues with the precision of the concrete foundation and support installation. These errors often affect the stress state of the truss structure and may even cause instability or deformation. Furthermore, most existing support designs are rigid. Once construction errors occur, the supports cannot be effectively adjusted, making it difficult to ensure support installation accuracy and affecting the overall stability of the truss.

[0004] To address this issue, existing technologies typically adjust the support installation position by increasing the size of embedded components or using steel plates or rebar pads. However, these methods cannot effectively address support angle errors, are still difficult to adjust during construction, and offer limited improvements in seismic performance. Therefore, how to precisely adjust the supports while ensuring their strength and stability, and especially how to maintain structural stability and seismic performance despite construction errors, has become a pressing technical challenge. Summary of the Invention

[0005] Based on the above objectives, the present invention provides an adjustable large-span space grid anti-seismic rotation support device.

[0006] An adjustable large-span space grid seismic rotation bearing device includes a pre-buried steel plate, four stiffening steel plates, a steel round tube, a rubber pad, a first positioning plate, a bearing rib plate, a second positioning plate, a first bearing upright plate, a second bearing upright plate, and a bearing ball;

[0007] Among them, four stiffening steel plates are arranged on the embedded steel plates, and their positions can be adjusted relative to the embedded steel plates to solve horizontal errors; the steel circular tube is fixed in the middle of the four stiffening steel plates, and the steel circular tube cooperates with other components to adjust the vertical position; the first positioning plate is fixed on the steel circular tube, and a rubber pad is arranged between the support rib plate and the first positioning plate; the second positioning plate is connected to the first positioning plate, the first support vertical plate and the second support vertical plate are fixedly connected to the second positioning plate, and the support ball is placed between the first support vertical plate and the second support vertical plate.

[0008] Through this technical solution, four stiffening steel plates are placed on the pre-embedded steel plates and can be adjusted relative to each other to account for horizontal errors. This means the horizontal position of the bearing can be fine-tuned during installation, effectively compensating for horizontal errors caused by construction errors or inaccurate installation of pre-embedded components. The fixed position of the steel tube allows for vertical adjustment, addressing vertical variations caused by construction errors. This adjustment feature helps minimize height errors during bearing installation, ensuring precise installation of the grid structure. The rubber pads, as part of the bearing, cushion vibrations and absorb seismic energy, thereby enhancing the seismic performance of the grid structure. The bearing ball, located between the bearing plate and the support plate, allows for rotation to accommodate angular errors in the grid structure or slight deviations caused by improper construction. This provides flexibility, allowing the bearing to accommodate angular errors during installation. This adjustable grid support can address common horizontal, vertical, and angular errors during construction, while also improving the bearing's seismic performance and ensuring the stability and safety of large-span grid structures.

[0009] Furthermore, the rubber pad is made of one or more flexible materials that can provide shock-resistant effects, and the flexible materials include rubber, elastic plastic, and polyurethane materials.

[0010] Through the above technical solution: by clearly stating that the rubber pad can be made of other flexible materials, such as rubber, elastic plastic, polyurethane, etc., the seismic function of the bearing can be made more flexible and adaptable to different construction environments and engineering needs. This design can adapt to seismic materials of different materials to meet different strength, elasticity and durability requirements, thereby improving the applicability of the bearing; it provides a variety of seismic material options, so that the bearing can be customized according to actual engineering needs, optimizing the balance between cost and performance. For example, for certain special environments, it may be more appropriate to use a certain material to improve durability or elasticity; by expanding the range of seismic material options, the applicability and flexibility of the bearing are improved, and at the same time, the adaptability of the invention is enhanced, and suitable flexible materials can be selected according to different construction needs to further improve the overall performance.

[0011] Furthermore, four stiffening steel plates are connected to the embedded steel plates, and the horizontal error is accommodated by adjusting the position of the stiffening steel plates.

[0012] The above technical solution effectively addresses horizontal errors caused by inaccurate positioning during construction by adjusting the position of the four reinforcing steel plates relative to the pre-embedded steel plates. This design allows for precise adjustment of the support positions, ensuring their correct horizontality and avoiding uneven support or structural instability caused by errors. Adjusting the reinforcing steel plates compensates for horizontal errors, ensuring the horizontality of the grid structure and improving structural accuracy and ease of installation.

[0013] Furthermore, the height of the steel round tube is adjustable, and the vertical error can be adjusted by adjusting the height.

[0014] The aforementioned technical solution, with its height-adjustable steel tubes, allows the support device to compensate for vertical variations caused by construction errors. By adjusting the height of the steel tubes, the vertical position of the supports can be precisely controlled, ensuring the verticality of the grid structure and avoiding structural instability or uneven stress caused by vertical errors. This height adjustment function overcomes vertical errors, ensures the vertical position accuracy of the supports, and improves the construction accuracy of long-span structures.

[0015] Furthermore, the support ball can rotate freely between the first support plate and the second support plate.

[0016] This technical solution allows the bearing ball to rotate freely between the bearing plate and the bearing upright, meaning the bearing can adapt to angular deviations caused by construction errors. The rotating bearing allows for flexible angle adjustment within a certain range, ensuring that the spherical bearing of the grid structure precisely mates with the grid assembly, avoiding the adverse effects of angular errors. By allowing the bearing ball to rotate, a flexible solution is provided to address angular errors during construction, allowing the grid support to adapt to slight angle changes and ensure structural stability.

[0017] Furthermore, the rubber pad between the first positioning plate and the support rib can absorb or mitigate vibration.

[0018] Through this technical solution, rubber pads placed between the support ribs and the positioning plates effectively mitigate and absorb vibration, especially under external forces such as earthquakes. The elastic properties of the rubber pads effectively reduce the transmission of vibration to the grid structure, thereby improving overall seismic performance. The use of rubber pads enhances the seismic resistance of the grid supports, helping to improve the performance of large-span grid structures in natural disasters such as earthquakes and enhancing the safety of the structure.

[0019] Furthermore, the support structure design can adapt to horizontal, vertical and angular errors generated during the construction process.

[0020] The above technical solution utilizes an adjustable design that allows the supports to adjust horizontal, vertical, and angular errors based on actual conditions. This is particularly true during construction, where different components may experience varying errors. This adjustable design allows the entire support system to adapt to specific on-site conditions, improving installation accuracy and ease of installation. The flexibility and adaptability of the support design allows it to effectively compensate for various errors during construction, ensuring the accuracy and stability of the grid structure.

[0021] Furthermore, the device is suitable for installing support nodes of large-span space grid structures.

[0022] The above technical solution demonstrates that the support device is suitable for installing support nodes in large-span spatial grid structures, demonstrating its wide application in large-span construction projects, particularly those requiring high construction precision and seismic resistance. This device provides a reliable support installation solution for large-scale construction projects, demonstrating its wide applicability, particularly in applications requiring high construction precision and seismic resistance, and thus increasing its market potential.

[0023] Beneficial effects of the present invention: The adjustable large-span space grid seismic rotatable bearing device of the present invention achieves precise adjustment of the bearing in the horizontal, vertical and angular directions through an innovative design, can effectively compensate for errors generated during the construction process, and ensure accurate installation of the bearing. This adjustment function solves the problem that traditional bearings cannot be flexibly adjusted during construction, and avoids structural instability caused by errors. The rubber pads (or other flexible materials) used in the bearing design enhance the seismic resistance of the bearing, effectively absorbing and mitigating the impact of external vibrations such as earthquakes on the grid structure, and improving the seismic resistance of the overall structure. In addition, by simplifying the installation process, the present invention shortens construction time, reduces labor costs, improves construction efficiency, and extends the service life of the grid structure. This technology has broad application prospects and is suitable for various spatial structures such as large-span steel grids and membrane structures, and has significant engineering application value.

[0033] Example 1

[0034] See Figures 1 to 3

[0035] An adjustable large-span space grid seismic rotation bearing device, comprising a pre-buried steel plate 1, four stiffening steel plates 2, a steel round tube 3, a rubber pad 4, a first positioning plate 5, a bearing rib 6, a second positioning plate 7, a first bearing upright plate 8, a second bearing upright plate 9, and a bearing ball 10;

[0036] Among them, four stiffening steel plates 2 are arranged on the embedded steel plate 1, and can be adjusted relative to the embedded steel plate 1 to solve horizontal errors; the steel circular tube 3 is fixed in the middle of the four stiffening steel plates 2, and the steel circular tube 3 cooperates with other components to adjust the vertical position; the first positioning plate 5 is fixed on the steel circular tube 3, and a rubber pad 4 is arranged between the support rib 6 and the first positioning plate 5; the second positioning plate 7 is connected to the first positioning plate 5, the first support vertical plate 8 and the second support vertical plate 9 are fixedly connected to the second positioning plate 7, and the support ball 10 is placed between the first support vertical plate 8 and the second support vertical plate 9.

[0037] Specifically, the rubber pad 4 is made of one or more flexible materials that can provide anti-seismic effects, and the flexible materials include but are not limited to rubber, elastic plastic, and polyurethane materials. Four stiffening steel plates 2 are connected to the embedded steel plate 1, and the horizontal error is adapted by adjusting the position of the stiffening steel plate. The height of the steel round tube 3 is adjustable, and the vertical error is adjusted by adjusting the height. The support ball 10 can rotate freely between the first support upright plate 8 and the second support upright plate 9. The rubber pad 4 between the first positioning plate 5 and the support rib plate 6 can absorb or slow down vibrations. The support structure design can adapt to the horizontal, vertical and angular errors generated during the construction process. The device is suitable for the support node installation of large-span space grid structures.

[0038] The adjustable, large-span space grid seismic-resistant rotating bearing device of this invention solves the horizontal, vertical, and angular errors caused by construction errors in large-span grid structures through its innovative structural design, while also enhancing the bearing's seismic performance. Its working principle is as follows:

[0039] Four stiffening steel plates 2 are evenly arranged on the embedded steel plate 1, and their position relative to the embedded steel plate 1 is adjustable. Adjusting the position of the stiffening steel plates effectively addresses horizontal position deviations of the supports caused by construction errors. This design allows the supports to translate horizontally on the embedded steel plate 1, ensuring accurate horizontal positioning and avoiding horizontal errors caused by inaccurate embedded component placement or uneven concrete foundations.

[0040] The steel tube 3 is fixed between the four reinforcing steel plates 2. The height of the steel tube 3 is adjustable, thus addressing vertical errors that may occur during construction. By adjusting the height of the steel tube, the vertical position of the support can be precisely controlled, ensuring the vertical accuracy of the support. This feature allows the support to adapt to vertical errors caused by improper construction, improves installation accuracy, and ensures the stability of the grid structure.

[0041] The rubber pads 4 are positioned between the first positioning plate 5 and the support ribs 6. Leveraging their elastic properties, they effectively absorb and mitigate shocks caused by earthquakes or other external vibrations. This cushioning effect mitigates the impact of vibrations on the grid structure, thereby enhancing the grid's seismic resistance. As flexible, seismic-resistant materials, the rubber pads 4 provide effective vibration isolation and energy dissipation, ensuring the safety and stability of the grid structure.

[0042] The bearing ball 10 is positioned between the first and second support plates 8 and 9, allowing it to rotate freely between the plates. This design effectively compensates for angular errors caused by construction errors, ensuring that the spherical bearings of the grid structure precisely mate with the superstructure. The ability to rotate the bearing ball allows the bearing to flexibly adapt to deviations caused by angular errors, reducing angular mismatches during installation and ensuring precise docking of the bearing system.

[0043] The second positioning plate 7, in conjunction with the first positioning plate 5, allows for further precise adjustment of the support's position. During support installation, the combination of the second positioning plate 7 with the first and second support uprights 8 and 9 allows for more precise adjustment of the support's horizontal and vertical position. This adjustment capability allows the support to adapt to various errors that may occur during construction, thereby ensuring the stability of the grid structure during installation.

[0044] This design allows the support system to be adjusted horizontally, vertically, and angularly, ensuring the accuracy and stability of the grid structure throughout the installation process. Whether due to positioning errors in embedded components, uneven concrete foundations, or angular errors, these can be compensated by adjusting various parts of the support, achieving precise installation.

[0045] The present invention provides an adjustable support device by combining four stiffening steel plates, steel circular tubes, rubber pads, support uprights, and support balls. This device can effectively compensate for horizontal, vertical, and angular deviations caused by errors during construction, while also improving the seismic performance of the support. The rotating design of the support ball provides flexibility, while the rubber pads enhance seismic performance. Overall, the present invention improves the installation accuracy of large-span space truss supports, ensures the stability and seismic resistance of the truss structure, and has broad engineering application prospects.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
