Description

Technical Field

[0001] This invention relates to the field of seismic resistance devices for building spatial structures, specifically to a modular high-damping rubber bearing node. Background Technology

[0002] In related technologies, with the rapid development of infrastructure construction in my country, large-span spatial structures have been widely used in major projects such as stadiums and transportation hubs. Against this backdrop, facing increasingly complex structural systems and diverse construction conditions, the structural selection of supports and their stress performance, especially their seismic performance, have attracted much attention.

[0003] Regarding support selection, traditional joint types that combine sliding and rotational properties mainly include steel spherical bearings and rubber plate bearings. Steel spherical bearings are made of high-strength cast steel, possessing excellent load-bearing capacity, mechanical stability, and durability. However, their manufacturing cost is significantly higher than rubber plate bearings, and damaged components must be replaced entirely, resulting in higher maintenance costs. Therefore, the application of this type of bearing is somewhat limited in small-to-medium span spatial structures where the bearing load is relatively low and project cost control is strict. Traditional rubber plate bearing joints transfer force to the rubber plate through cross-shaped ribs, with bolts positioned in the core load-bearing area of ​​the joint, resulting in uniform stress on the rubber plate. However, when the joint is a short column connection, the cross-shaped ribs are replaced with box-section or cylindrical sections, forcing the bolts to be moved outside the core load-bearing area. This arrangement not only requires a corresponding increase in the geometric dimensions of the rubber plate but also leads to uneven stress on the rubber plate under load, thus affecting the translational and rotational performance of the support. Meanwhile, the bolts of traditional plate rubber bearings penetrate the rubber pad. During the service life of the structure, if the rubber material corrodes and ages, affecting the normal use of the bearing, the replacement of the rubber pad will face great construction difficulties, and may even be impossible due to limited operating space. In addition, the application of existing bearings is also limited for small-to-medium span spatial structures located in high-intensity seismic zones or subjected to dynamic loads.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the invention will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0022] To address the shortcomings and deficiencies of existing technologies, this exemplary embodiment provides a modular high-damping rubber support node. The modular high-damping rubber support node of this exemplary embodiment will now be described in more detail with reference to the accompanying drawings and embodiments.

[0023] For example, refer to Figure 1 As shown, the modular high-damping rubber bearing node includes: a steel structure column top plate 1, a high-damping rubber bearing assembly 2, a spatial structure bearing bottom plate 3, a channel steel plate 5, and a hydraulic rotation assembly 6.

[0024] Specifically, a high-damping rubber bearing assembly 2 is installed at the center of the steel structure column top plate 1; multiple channel-shaped steel plates 5 are symmetrically arranged on the outer side of the high-damping rubber bearing assembly 2; a spatial structure support base plate 3 is installed on the top of the high-damping rubber bearing assembly 2 and is movably connected to the channel-shaped steel plates 5 through a hydraulic rotating assembly 6; multiple limiting devices 7 are symmetrically distributed at the corners of the steel structure column top plate 1 on the outer side of the high-damping rubber bearing assembly 2; a sliding gap is left between the limiting devices 7 and each high-damping rubber bearing assembly 2. The high-damping rubber bearing assembly is placed in the core area of ​​the node, the hydraulic rotating assembly is placed outside the core area of ​​the node, and the limiting devices are placed at the corners of the node, with a certain sliding gap between the limiting devices and the core area of ​​the node.

[0025] For example, refer to Figure 8As shown, the high-damping rubber bearing assembly 2 includes: a damping rubber bearing body 21; sealing steel plates 22 are respectively provided on the upper and lower sides of the damping rubber bearing body 21; a high-damping rubber bearing steel plate 23 is provided on the outer layer of each sealing steel plate 22; wherein, the high-damping rubber bearing steel plate 23 located at the bottom layer is fixed on the top plate 1 of the steel structure column; the sealing steel plate 22 has the same size as the damping rubber bearing body 21; and the size of the sealing steel plate 22 is smaller than the size of the high-damping rubber bearing steel plate 23.

[0026] Specifically, the high-damping rubber bearing assembly 2 mainly consists of a damping rubber bearing body 21, a sealing steel plate 22, and a bearing steel plate 23. A sealing steel plate 22 is installed on both the upper and lower sides of the damping rubber bearing body 21; the damping rubber bearing body 21 and the sealing steel plate 22 can be integrally bonded through a high-temperature vulcanization process. A high-damping rubber bearing steel plate 23 can be installed on the outer layer of the top and bottom sealing steel plates 22; and high-strength bolts can be used to mechanically connect the high-damping rubber bearing steel plate 23 to the sealing steel plate 22, ultimately forming the complete high-damping rubber bearing assembly 2.

[0027] Among them, the high-damping rubber bearing steel plate 23 at the top layer can have inwardly recessed arc-shaped notches at the four top corners; the notches can match the structure of the space structure bearing base plate 3.

[0028] refer to Figure 9 As shown, the top plate 1 of the steel structure column can be pre-drilled with connection holes for assembling the channel steel plate 5, the high damping rubber bearing assembly 2, and the limiting device 7.

[0029] The high-damping rubber bearing assembly 2 has a bottom high-damping rubber bearing steel plate 23 that can be bolted to the upper surface of the steel structure column top plate 1. Additionally, the space structure bearing base plate 3 can be fixed to the top high-damping rubber bearing steel plate 23 using high-strength bolts. Fixing holes can be pre-drilled on each high-damping rubber bearing steel plate 23.

[0030] For example, each side of the high-damping rubber bearing assembly 2 is provided with a dustproof plate 4; each dustproof plate 4 cooperates with the high-damping rubber bearing steel plate 23 at the top and bottom layers of the high-damping rubber bearing assembly 2 to enclose the damping rubber bearing body 21; wherein, the bottom of the dustproof plate 4 is fixed on the high-damping rubber bearing steel plate 23 at the bottom layer of the high-damping rubber bearing assembly 2.

[0031] For details, please refer to Figure 11 , Figure 12As shown, a vertically placed dustproof plate 4 can be provided on each of the four side walls of the damping rubber bearing body 21. Each dustproof plate 4 is connected end to end and fixed to the high-damping rubber bearing steel plate 23 on the upper and lower sides, forming a closed enclosure of the high-damping rubber bearing assembly 2.

[0032] Alternatively, the dustproof plate 4 can be fixed between the base plate 3 of the spatial structure support and the top plate 1 of the steel structure column to achieve a reliable connection.

[0033] For example, the space structure support base plate 3 has a cross-shaped structure; the center of the space structure support base plate 3 is provided with a fixing hole for fixing to the high damping rubber support assembly 2; the cross extension portion of the space structure support base plate 3 is provided with a connection hole for assembling the hydraulic rotating assembly 6.

[0034] For details, please refer to Figure 1 , Figure 10 , Figure 11 As shown, the space structure support base plate 3 has a cross-shaped structure, including a main body located at the center and extensions extending outward in four directions. The main body at the center has fixing holes and is fixed to the top surface of the high-damping rubber support assembly 2 with bolts. Each extension has a connection hole.

[0035] For example, the channel steel plate 5 has a gate-shaped structure; the top of the channel steel plate 5 is provided with a connection hole for assembling the pressure rotating assembly 6.

[0036] For details, please refer to Figure 1 , Figure 5 , Figure 12 As shown, the channel steel plate 5 has a U-shaped structure. A channel steel plate 5 is provided on each of the four sides of the high-damping rubber bearing assembly 2, and is inverted and fixed to the top plate 1 of the steel structure column. For example, the channel steel plate can be reliably connected to the top plate 1 of the steel structure column by welding.

[0037] For example, the hydraulic rotating assembly 6 includes: a hydraulic rod 61; a small spherical cast steel part 62 for cooperating with the space structure support base plate 3 on the upper part of the hydraulic rod 61; a large spherical cast steel part 63 for cooperating with the channel steel plate 5 on the lower part of the hydraulic rod 61; and a nut 65 for fastening the hydraulic rotating assembly 6 at the lower end of the large spherical cast steel part 63.

[0038] For example, pads 64 are respectively provided in close contact with the underside of the small spherical cast steel part 62 and the large spherical cast steel part 63.

[0039] Specifically, refer to Figures 1-3 , Figure 13 , Figure 14As shown, the hydraulic rotation assembly 66 mainly consists of a hydraulic rod 61, a small spherical cast steel part 62, and a large spherical cast steel part 63. Each component is connected through a channel steel plate 5 and a spatial structure support base plate 3, and secured by gaskets 64 and nuts 65, forming a complete translational and rotational system. To achieve effective translation and rotation of the support nodes, the large spherical cast steel part, the channel steel plate, and the spatial structure support all require corresponding connection holes, the diameter of which is determined by calculation. Specifically, the large spherical cast steel part adopts a hemispherical design with a conical hole at its geometric center; the small spherical cast steel part also adopts a hemispherical design with a hole at its geometric center, the diameter of which should be 2mm larger than the diameter of the hydraulic rod. (Reference) Figure 14 As shown, the small spherical cast steel part 62 is fixed to the upper surface of the space structure support base plate 3 by the pad 64; the hemispherical structure of the large spherical cast steel part 63 is upside down on the inner side of the top of the channel steel plate, and the pad 64 is placed on the top of the arc of the hemispherical structure of the large spherical cast steel part 63 and fastened by the nut 65.

[0040] For example, the limiting device 7 includes a connecting plate 72 and a box-shaped column 71 vertically arranged on the connecting plate 72; wherein, the inner cavity of the box-shaped column 71 is provided with a cross stiffening rib 74; and the side wall of the box-shaped column 71 is provided with a diamond-shaped hole 73.

[0041] For details, please refer to Figure 15 As shown, a box-section column 71 with a cubic structure is vertically placed at the center of the bottom connecting plate 72; fixing holes are also provided on the edge of the connecting plate 72. Diamond-shaped holes 73 can also be provided at the lower part of each side wall of the box-section column 71. (Reference) Figure 16 As shown, a cross-shaped stiffening rib 74 may be provided in the upper part of the inner cavity of the box-section column 71, that is, above the rhomboid hole 73. (Reference) Figure 1 As shown, a limiting device 7 can be fixed at each of the four corners of the top plate 1 of the steel structure column, and fixed to the upper surface of the top plate 1 of the steel structure column with high-strength bolts.

[0042] By setting a cross-shaped stiffening rib plate in the upper part of the inner cavity of the box-section column 71, when an earthquake occurs, when the horizontal displacement exceeds the blocking gap of the limiting device, the limiting device starts to work, and the diamond-shaped hole begins to yield, thereby enhancing the energy dissipation capacity of the structure.

[0043] For example, the construction and installation process is as follows: Install the reinforced concrete column top embedded plate 1 (steel structure column top plate) at the construction site, with pre-drilled threaded holes for the high-damping rubber components. Assemble the high-damping rubber bearing body 21, sealing steel plate (22), and high-damping rubber bearing steel plate 23 in the factory beforehand, and pre-drill threaded holes for the high-damping rubber bearing steel plate 23. Then, fix the high-damping rubber component 2 to the reinforced concrete column top embedded plate 1 (steel structure column top plate) at the construction site using high-strength bolts. Pre-fabricate the spatial structure base plate 3 in the factory beforehand, and then install the spatial structure base plate 3 to the high-damping rubber component 2 at the construction site using high-strength bolts. Finally, fix the dustproof plate 4 to the high-damping rubber bearing steel plate 23. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) The channel steel plate 5 is welded and then welded onto the pre-embedded plate 1 at the top of the reinforced concrete column on site. The large spherical cast steel component 32, the small spherical welded component 62, the hydraulic rod 61, the pad 64, and the nut 65, after being custom-made in the factory, are assembled on site to form the hydraulic rotating assembly 6. The hydraulic rotating assembly 6 is put into operation by adjusting the nut. The box-section column 71, connecting plate 72, and cross stiffening rib 74 are custom-made in the factory, and diamond-shaped holes 73 are drilled on the box-section column 71. These components are then assembled to form the limiting device 7, which is fixed to the pre-embedded plate (steel structure column top plate) at the top of the reinforced concrete column on site using high-strength bolts.

[0044] The modular high-damping rubber bearing node provided by this invention adopts a functional zoning and modular design concept. The high-damping rubber bearing components are arranged in the core area of ​​the node, primarily bearing vertical pressure and dissipating horizontal energy. The hydraulic rotation components are arranged around the core area, mainly coordinating horizontal deformation, bearing tensile and compressive forces, and controlling rotation. All functional components adopt a standardized modular design, forming a reliable connection with the bearing body using high-strength bolts. This construction method has the following advantages: ① It can be applied to various node connection forms, with a clear force transmission path; ② It can achieve vibration reduction and energy dissipation, improving the seismic resistance of the structure; ③ The modular design has a high degree of assembly, facilitating node maintenance and rapid installation and replacement.
