Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a hinged joint device. Background Technology

[0002] Currently, in the field of steel structure construction, there are various types of building joints, each with its own characteristics. However, in practical applications, rigid joints and hinged joints are the most widely used. They are typically installed in multiple connection areas between the superstructure and substructure of a steel structure. In contemporary steel structure construction practice, the design and application of hinged joints have certain limitations. When the structure is subjected to external loads, such as complex forces like earthquakes and wind, they typically cannot achieve mutual rotation and torsion in space. Under this design mode, the deformation capacity of hinged joints is significantly limited. Because they cannot fully adapt to various complex stress conditions and deformation requirements, the load-bearing capacity of the joint itself cannot be fully utilized. Consequently, the entire structure cannot fully mobilize the potential of the joints during stress, and the overall load-bearing capacity of the structure cannot be fully realized. Therefore, we propose a hinged joint device to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a hinged node device that solves the problem that hinged nodes cannot achieve mutual rotation and torsion in space, thus limiting their load-bearing capacity.

[0004] This utility model is achieved through the following solution: a hinged joint device, comprising multiple hinged supports for being respectively disposed in multiple connection areas of the upper and lower structures of a steel structure, wherein the hinged supports include:

[0005] Connector, used to fix it to the top of the lower structure;

[0006] The base is mounted on the connector;

[0007] A pin is rotatably connected to the base;

[0008] A radial spherical bearing, wherein the inner ring of the radial spherical bearing is fixedly sleeved on the outside of the pin; and

[0009] A top seat is used for fixed connection to the bottom of the upper structure, and the top seat is fixedly connected to the outer ring of the radial spherical bearing.

[0010] A further improvement of the hinged joint device of this utility model is that the connecting seat includes a protective frame, the protective frame is fixed to the top of the lower structure, and the top of the protective frame is provided with a groove for placing the base.

[0011] A further improvement of the hinge node device of this utility model is that the base includes a base plate and a load-bearing plate, the base plate is placed in a groove, the size of the groove is larger than the size of the base plate, so that the base plate can move within the groove, the load-bearing plate is vertically fixed to the top of the base plate, and the pin is rotatably connected through the load-bearing plate.

[0012] A further improvement of the hinged joint device of this utility model is that the number of the load-bearing plates is at least two, and the at least two load-bearing plates are arranged at intervals, and the pin shaft is rotatably connected through all the load-bearing plates.

[0013] A further improvement of the hinge node device of this utility model is that the number of the radial joint bearings is at least two, and the at least two radial joint bearings and the at least two load-bearing plates are arranged alternately at intervals.

[0014] A further improvement of the hinge node device of this utility model is that the top seat includes a top plate and a connecting plate. The top plate is fixedly connected to the bottom of the upper structure. The number of connecting plates is the same as the number of radial joint bearings and their positions correspond one-to-one. All the connecting plates are vertically fixedly connected to the bottom of the top plate. Each connecting plate is provided with a shaft hole for the outer ring of the corresponding radial joint bearing to be fixedly fitted.

[0015] A further improvement of the hinge node device of this utility model is that a low friction coefficient plate is provided at the bottom of the groove, and the base is placed on the low friction coefficient plate.

[0016] A further improvement of the hinged joint device of this utility model is that the connecting seat further includes multiple stiffening plates, all of which are fixedly connected to the outside of the protective frame, and the multiple stiffening plates are arranged in a ring around the outer perimeter of the protective frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting a pin, allows the node to rotate smoothly in one direction under load, while the central radial joint bearing ensures small-amplitude rotation in the other direction. This greatly enhances the deformation capacity of the structure. When the structure is subjected to external loads, rotation can be achieved through the pin when the turning angle is small, and large-angle rotation can be achieved through the combined action of the pin and the radial joint bearing when the turning angle is large, thus realizing the function of free rotation in both directions. The hinged node device can adapt to the deformation requirements of the structure through its own translation and rotation, effectively dispersing and transferring loads, avoiding local stress concentration, and thus protecting the overall stability of the structure.

[0025] To address the problem that hinged joints cannot achieve mutual rotation and torsion in space, thus limiting their load-bearing capacity, this invention provides a hinged joint device. The following detailed description, in conjunction with the accompanying drawings, illustrates this hinged joint device with specific embodiments.

[0026] See Figures 1-5 As shown, a hinged joint device includes multiple hinged supports for being respectively disposed in multiple connection areas of the upper structure 6 and the lower structure 7 of a steel structure. The hinged supports include:

[0027] A connecting seat is used to fix it to the top of the lower structure 7;

[0028] The base is mounted on the connector;

[0029] Pin 8 is rotatably connected to the base;

[0030] A radial spherical bearing 11, the inner ring of which is fixedly sleeved on the outside of the pin 8; and

[0031] The top seat is used for fixed connection to the bottom of the upper structure 6, and the top seat is fixedly connected to the outer ring of the radial spherical bearing 11.

[0032] This application utilizes a pin 8 to allow the node to rotate smoothly in one direction under load, while the central radial joint bearing 11 ensures a small-amplitude rotation in the other direction. This gives the hinged node a unique performance advantage, enabling rotation in both horizontal directions. This characteristic greatly enhances the structure's deformation capacity. When the structure is subjected to external loads, such as earthquakes or wind forces, small rotation angles can be achieved through the pin 8, while large rotation angles can be achieved through the combined action of the pin 8 and the radial joint bearing 11, thus enabling free rotation in both directions. This hinged node can adapt to the deformation requirements of the structure through its translation and rotation, effectively distributing and transferring loads, avoiding local stress concentration, and protecting the overall stability of the structure. Simultaneously, this excellent deformation capacity further enhances the structure's load-bearing capacity, allowing the structure to fully utilize the load-bearing potential of each component through reasonable deformation coordination when subjected to large loads, thereby improving the overall load-bearing efficiency of the structure. In practical engineering applications, these advantages can provide more reliable mechanical performance guarantees for steel structure buildings, meet the requirements of different building structures for deformation and load-bearing capacity, and promote the development of steel structure building technology to a higher level.

[0033] Among them, see Figure 1-2 As shown, the connecting seat includes a protective frame 3, which is fixed to the top of the lower structure 7, and the top of the protective frame 3 is provided with a groove 4 for the base to be placed.

[0034] The base includes a base plate 2 and a load-bearing plate 10. The base plate 2 is placed in a groove 4, and the size of the groove 4 is larger than the size of the base plate 2 so that the base plate 2 can move within the groove 4. The load-bearing plate 10 is vertically fixed to the top of the base plate 2, and a pin 8 is rotatably connected to the load-bearing plate 10.

[0035] By adopting the above design, when the structure is subjected to external loads, the base plate 2 on the multiple hinged supports can slide laterally along the corresponding groove 4, which can well adapt to the deformation requirements of the steel structure and effectively disperse and transfer the load.

[0036] Among them, see Figure 2 , 4 As shown in Figure 5, in this embodiment, there are three load-bearing plates 10, and the three load-bearing plates 10 are arranged at intervals, with the pin shaft 8 rotatably connected through all the load-bearing plates 10.

[0037] By adopting the above design, the overall strength of the hinged joint device of this application can be improved by using three load-bearing plates 10, thereby improving the load-bearing capacity.

[0038] Among them, see Figure 4 and 5As shown, in this embodiment, there are two radial joint bearings 11, and the two radial joint bearings 11 and the three load-bearing plates 10 are arranged alternately at intervals.

[0039] The top plate includes a top plate 1 and a connecting plate 9. The top plate 1 is fixedly connected to the bottom of the upper structure 6. The number of connecting plates 9 is the same as the number of radial spherical bearings 11 and their positions correspond one-to-one. All connecting plates 9 are vertically fixedly connected to the bottom of the top plate 1. Each connecting plate 9 has a shaft hole for the outer ring of the corresponding radial spherical bearing 11 to be fixedly fitted.

[0040] By adopting the above design, using two connecting plates 9 to connect to two radial spherical bearings 11 respectively, and two sets of torsion nodes, the torsional stability of the articulated node device of this application can be improved during use, and the load-bearing efficiency can be increased.

[0041] Among them, see Figure 1 and 3 As shown, a low-friction coefficient plate 5 is provided at the bottom of the groove 4, and the base is placed on the low-friction coefficient plate 5.

[0042] Furthermore, the low-friction coefficient plate 5 can be a plate made of polytetrafluoroethylene, which has good wear resistance, corrosion resistance and self-lubricating properties, and can ensure the horizontal bidirectional translation of the node; during the horizontal movement of the node, it can effectively reduce frictional resistance, ensure the flexible movement of the node, and also improve the service life of the node.

[0043] Among them, see Figure 1 As shown, the connecting seat also includes multiple stiffening plates 301, which are all fixedly connected to the outside of the protective frame 3, and the multiple stiffening plates 301 are arranged in a ring around the outer perimeter of the protective frame 3.

[0044] By adopting the above design, the protective frame 3 can prevent the node device from deforming too much horizontally and detaching from the top of the lower steel structure. By setting stiffening plate 301, the horizontal bearing capacity of the protective frame 3 is improved, and the excessive horizontal force on the node is prevented from damaging the node.
