Description

Technical Field

[0001] The 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 buildings and large industrial facilities, large-span steel grid structures have been widely used in large-span buildings such as stadiums, exhibition halls, airport terminals, etc. due to their beautiful appearance and efficient structural characteristics. Large-span space grid structures are usually composed of grid balls, bearings, steel pipes and other components. The bearings are the connecting parts between the grid structure and the lower concrete structure. Their stability and accuracy have an important impact on the safety and seismic performance of the overall structure.

[0003] However, in the construction process of large-span grids, vertical and horizontal errors often occur due to the accuracy of concrete foundation and support installation. These errors often affect the stress state of the grid structure and even cause the grid to become unstable or deformed. In addition, most of the existing support designs are rigid supports. Once there is a construction error, the support cannot be effectively adjusted, making it difficult to ensure the installation accuracy of the support, affecting the overall stability of the grid.

[0004] In order to solve this problem, the existing technology usually adjusts the installation position of the support by increasing the size of the embedded parts, using steel plates or steel bars, etc., but these methods cannot effectively solve the angle error of the support, and there is still great difficulty in adjustment during the construction process, and the improvement of seismic performance is limited. Therefore, how to achieve precise adjustment of the support while ensuring the strength and stability of the support, especially how to maintain the stability and seismic performance of the structure in the face of construction errors, has become a technical problem that needs to be solved urgently. Summary of the invention

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

[0006] An adjustable large-span space grid seismic rotation bearing device comprises 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; 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, and the first support vertical plate and the second support vertical plate cooperate with the second positioning plate through connection, and the support ball is placed between the first support vertical plate and the second support vertical plate.

[0007] Through the above technical solution: four stiffening steel plates are arranged on the embedded steel plate and can be relatively adjusted to solve the horizontal error. This means that the horizontal position of the support can be fine-tuned during the installation process, thereby effectively compensating for the horizontal error caused by construction errors or inaccurate installation of embedded parts; through the fixed position of the steel round tube, the vertical position can be adjusted to solve the vertical difference caused by construction errors. This adjustment function helps to reduce the height error during the installation of the support and ensure the accurate installation of the grid structure; the rubber pad, as part of the support, can buffer vibrations and absorb seismic energy, thereby improving the seismic performance of the grid structure; the support ball is located between the support plate and the support plate, which can provide the support rotation function to adapt to the angular error of the grid structure or slight deviation caused by improper construction. This makes the support have a certain flexibility and can adapt to the angular error during the installation process; the adjustability of the grid support is realized, which can solve the common horizontal error, vertical error and angular error during the construction process, while improving the seismic performance of the support and ensuring the stability and safety of the large-span space grid structure.

[0008] Furthermore, the rubber pad is made of one or more flexible materials that can provide shock-resistant effects, and the flexible materials include but are not limited to rubber, elastic plastic, and polyurethane materials.

[0009] Through the above technical solution: by clearly pointing out 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, and improve 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 some special environments, it may be more appropriate to use a certain material to improve durability or elasticity; by expanding the range of seismic material selection, the applicability and flexibility of the bearing are improved, and at the same time, the adaptability of the invention is enhanced. Suitable flexible materials can be selected according to different construction needs to further improve the overall performance.

[0010] Furthermore, four stiffening steel plates are connected to the embedded steel plate, and the horizontal error is accommodated by adjusting the position of the stiffening steel plates.

[0011] Through the above technical solution: by adjusting the position of the four stiffening steel plates relative to the embedded steel plates, the horizontal error problem caused by inaccurate positioning during construction can be effectively solved. This design can accurately adjust the position of the support to ensure the correctness of the horizontal state of the support and avoid uneven support or structural instability caused by errors; by adjusting the stiffening steel plates, the horizontal error is compensated, thereby ensuring the horizontality of the grid structure and improving the accuracy of the structure and the convenience of installation.

[0012] Furthermore, the height of the steel round tube is adjustable, and the vertical error can be adjusted by adjusting the height.

[0013] Through the above technical solution: the height adjustable function of the steel round tube enables the support device to compensate for the vertical difference caused by construction errors. By adjusting the height of the steel round tube, the vertical position of the support can be accurately controlled to ensure the verticality of the grid structure and avoid structural instability or uneven force caused by vertical errors. The height adjustment function solves the problem of vertical errors, ensures the vertical position accuracy of the support, and improves the construction accuracy of large-span structures.

[0014] Furthermore, the support ball can rotate freely between the first support stand plate and the second support stand plate.

[0015] Through the above technical solution: the support ball can rotate freely between the support plate and the support plate, which means that the support can adapt to the angle deviation caused by construction errors. The rotating support can flexibly adjust the angle within a certain range to ensure that the spherical support of the grid structure can accurately dock with the grid assembly to avoid the adverse effects of angle errors; by allowing the support ball to rotate, a flexible solution is provided to deal with angle errors during construction, so that the grid support can adapt to slight angle changes and ensure structural stability.

[0016] Furthermore, the rubber pad between the first positioning plate and the support rib plate can absorb or mitigate vibration.

[0017] Through the above technical solution: the rubber pad is set between the support rib plate and the positioning plate, which can effectively reduce and absorb vibration, especially under the action of external forces such as earthquakes. Through the elastic characteristics of the rubber pad, the support can effectively reduce the transmission of vibration to the grid structure, thereby improving the overall seismic performance; through the application of rubber pads, the seismic resistance of the grid support is enhanced, which helps to improve the performance of large-span space grid structures in natural disasters such as earthquakes and enhance the safety of the structure.

[0018] Furthermore, the support structure design can accommodate horizontal, vertical and angular errors generated during the construction process.

[0019] Through the above technical solution: through the adjustable design, the support can adjust the horizontal, vertical and angular errors according to the actual situation. Especially during the construction process, since different parts may have different errors, through this adjustable design, the entire support system can adapt to the specific conditions on site, thereby improving the installation accuracy and installation convenience of the support; the flexibility and adaptability of the support design enable the support to effectively compensate for various errors during the construction process, ensuring the accuracy and stability of the grid structure.

[0020] Furthermore, the device is suitable for the installation of support nodes of large-span space grid structures.

[0021] Through the above technical solution: the support device is suitable for the installation of support nodes of large-span space grid structures, indicating that the device can be widely used in large-span construction projects, especially structures with high requirements for construction accuracy and earthquake resistance. The device provides a reliable support installation solution for large-scale construction projects, with strong applicability; wide applicability, especially for occasions with high requirements for construction accuracy and earthquake resistance, increases its market application potential.

[0022] Beneficial effects of the present invention: The adjustable large-span space grid seismic rotating bearing device of the present invention realizes precise adjustment of the bearing in the horizontal, vertical and angular directions through innovative design, can effectively compensate for the errors generated during the construction process, and ensure the precise 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 absorb and mitigate the impact of external vibrations such as earthquakes on the grid structure, and improve the seismic resistance of the overall structure. In addition, the present invention shortens the construction time, reduces labor costs, improves construction efficiency, and prolongs the service life of the grid structure by simplifying the installation process. The 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.

Example

[0029] See also Figures 1 to 3 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 plate 6, a second positioning plate 7, a first bearing upright plate 8, a second bearing upright plate 9 and a bearing ball 10; Among them, four stiffening steel plates 2 are arranged on the embedded steel plate 1, and their positions 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 plate 6 and the first positioning plate 5; the second positioning plate 7 is connected to the first positioning plate 5, and the first support vertical plate 8 and the second support vertical plate 9 are coordinated with the second positioning plate 7 through connection, and the support ball 10 is placed between the first support vertical plate 8 and the second support vertical plate 9.

[0030] 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 bearing ball 10 can rotate freely between the first bearing upright plate 8 and the second bearing upright plate 9. The rubber pad 4 between the first positioning plate 5 and the bearing rib plate 6 can absorb or reduce vibrations. The bearing 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.

[0031] The adjustable large-span space grid seismic rotating support device of the present invention solves the horizontal, vertical and angular error problems caused by construction errors in large-span grid structures through innovative structural design, and at the same time enhances the seismic performance of the support. Its working principle is as follows: Four stiffening steel plates 2 are evenly arranged on the embedded steel plate 1, and the positions of these stiffening steel plates 2 can be adjusted relative to the embedded steel plate 1. By adjusting the positions of the stiffening steel plates, the horizontal position deviation of the support caused by construction errors can be effectively solved. This design enables the support to translate on the embedded steel plate 1, ensuring the accurate position of the support on the horizontal plane and avoiding horizontal errors caused by inaccurate positions of embedded parts or uneven concrete foundations.

[0032] The steel round tube 3 is fixed between the four stiffening steel plates 2. The height of the steel round tube 3 can be adjusted to solve the vertical error generated during the construction process. By adjusting the height of the steel round tube, the vertical position of the support can be accurately controlled to ensure the accuracy of the support in the vertical direction. This function enables the support to adapt to the vertical error caused by improper construction, improve the installation accuracy, and ensure the stability of the grid structure.

[0033] The rubber pad 4 is arranged between the first positioning plate 5 and the support rib 6. The elastic properties of the rubber pad can effectively absorb and mitigate the impact caused by earthquakes or other external vibrations. This buffering effect can reduce the impact of vibration on the grid structure, thereby enhancing the seismic performance of the grid. As a flexible seismic material, the rubber pad 4 plays an effective role in vibration isolation and energy dissipation, ensuring the safety and stability of the grid structure.

[0034] The support ball 10 is placed between the first support plate 8 and the second support plate 9, and the support ball 10 can rotate freely between the support plates. This design can effectively compensate for the angle error caused by construction error, ensuring that the spherical support of the grid structure can be accurately docked with the upper structure. The function of rotating the support ball allows the support to flexibly adapt to the deviation caused by the angle error, reduce the problem of angle mismatch during installation, and ensure the accurate docking of the support system.

[0035] The second positioning plate 7 can further accurately adjust the position of the support by cooperating with the first positioning plate 5. During the installation of the support, the combination of the second positioning plate 7 and the support uprights 8 and 9 allows for more accurate adjustment of the horizontal and vertical positions of the support. This adjustment function enables the support to adapt to various errors that may occur during the construction process, thereby ensuring the stability of the grid structure during the installation process.

[0036] Through the above design, the support system can be adjusted in three dimensions: horizontal, vertical and angle, ensuring the accuracy and stability of the grid structure during the entire installation process. Whether it is due to the positioning error of the embedded parts, the uneven concrete foundation, or the angle error, it can be compensated by adjusting the various parts of the support, thereby achieving the purpose of precise installation.

[0037] The present invention provides a support device with an adjustable function by combining four stiffening steel plates, steel round tubes, rubber pads, support uprights, support balls and other components. It can effectively compensate for the horizontal, vertical and angular deviations caused by errors during the construction process, while improving the seismic performance of the support. The rotating design of the support ball makes it flexible, and the rubber pad enhances the seismic performance. Overall, the present invention improves the installation accuracy of large-span space grid supports, ensures the stability and seismic resistance of the grid structure, and has broad engineering application prospects.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] 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 principle of the present invention.
