Description

Technical Field

[0001] This invention relates to the field of seismic-resistant space frame structures, specifically a universal seismic-resistant sliding support device for steel space frames. Background Technology

[0002] Spherical supports for steel space frames are widely used in steel space frame structures, primarily to bear vertical loads. Steel space frame structures are frequently used in large-span spatial structures such as stadiums and exhibition halls. The supporting columns and connecting columns of a space frame structure are typically connected by welding. The supporting columns provide support force, while the connecting columns distribute the load. These columns are usually connected using a high-strength rigid connection method. While this method offers high strength, its seismic resistance is limited. During strong vibrations (such as earthquakes), the connection structure between the supporting and connecting columns is prone to fracture under high impact loads, leading to significant economic losses and casualties. Therefore, in modern steel space frame construction, seismic factors must be fully considered. It is necessary to add seismically resistant connecting components between the supporting and connecting columns to reduce the impact load and recovery capacity under vibration, thereby improving the connection toughness of the steel space frame structure. Summary of the Invention

[0003] In view of this, in order to reduce the impact load on the supporting columns and connecting columns of the steel space frame structure under vibration and improve the seismic resistance and connection toughness of the steel space frame structure, the present invention provides a universal seismic sliding support device for steel space frame, including supporting columns, fixed seats, sliding blocks, circular buckles, and connecting columns.

[0004] The fixing base includes a fixing buckle and a base plate. The fixing buckle is fixed to the top of the support column, and the base plate is located inside the fixing buckle. The fixing buckle is provided with a mounting hole, and the upper surface of the base plate is provided with a sliding groove. The edge of the mounting hole presses against and fixes the edge of the base plate.

[0005] The lower part of the slider is slidably disposed within the sliding groove.

[0006] The slider component is fitted with an upper ring sleeve, and the circular buckle plate is fastened to the outside of the upper ring sleeve. Multiple hydraulic damping cylinders are provided between the inner wall of the circular buckle plate and the outer wall of the upper ring sleeve.

[0007] All connecting posts are connected to the circular buckle plate.

[0008] Furthermore, the bottom of the slider is an arc-shaped surface, the sliding groove is an arc-shaped groove, and the bottom of the slider is slidably supported in the sliding groove.

[0009] Furthermore, the top of the support column is provided with at least three limiting columns, and the slider is located between the three limiting columns.

[0010] Furthermore, the circular buckle plate is also provided with a hemispherical shell, the bottom of which is fixed to the upper surface of the circular buckle plate, and the ends of all connecting posts are vertically fixed to the hemispherical shell.

[0011] Furthermore, the hemispherical shell is provided with a reinforcing support member, which includes a connecting base plate and two semi-circular support plates. The connecting base plate is fixed to the circular buckle plate, and the two semi-circular support plates are perpendicularly connected to the connecting base plate and support the inner surface of the hemispherical shell.

[0012] Furthermore, the hydraulic damping cylinder includes a cylinder body, a piston plate, and a piston rod. The piston plate is slidably disposed in the cylinder body, and the end of the piston rod is connected to the piston plate. Both the cylinder body and the piston rod have connecting ends, and the two connecting ends are respectively connected to the outer wall of the upper ring sleeve and the inner wall of the circular buckle plate. At least two one-way pressure reducing valves are provided on the piston plate.

[0013] Furthermore, hydraulic oil is injected into the cylinder body, and the piston plate divides the two cylinder body cavities into two hydraulic chambers. Both one-way pressure reducing valves are connected to the two hydraulic chambers, and the two one-way pressure reducing valves allow hydraulic oil to flow in opposite directions.

[0014] Furthermore, both the outer side of the upper ring sleeve and the inner wall of the circular buckle plate are provided with limiting holes, and the two connecting ends on the cylinder body and piston rod are respectively limited within the two limiting holes.

[0015] Furthermore, the top of the circular buckle plate is located on the top plate, and the top of the slider is provided with a first elastic element, which is an elastic pad made of rubber.

[0016] Furthermore, a second elastic element, which is a helical spring, is also fitted over the first elastic element.

[0017] The beneficial effects of the steel space frame universal seismic sliding bearing device of the present invention are as follows: The seismic sliding bearing device includes a support column, a fixed seat, a slider, a circular buckle plate, and a connecting column; the fixed seat is fixed to the top of the support column, and a bottom support plate is fixed inside the fixed seat. The bottom support plate is provided with a sliding groove. The slider is slidably supported in the sliding groove through the arc surface. The slider is covered with an upper ring sleeve, and the circular buckle plate is fastened to the outside of the upper ring sleeve. Multiple hydraulic damping cylinders are provided between the inner wall of the circular buckle plate and the outer wall of the upper ring sleeve. The hydraulic damping cylinders surround and are perpendicular to the upper ring sleeve. All hydraulic damping cylinders can provide centripetal support force to the slider through its axis. When the connecting column and the support column vibrate and displace relative to each other, all hydraulic damping cylinders generate resistance to the eccentric movement of the slider, thereby reducing the vibration damping of the connection structure between the connecting column and the support column and preventing the vibration impact force between the connecting column and the support column from damaging the connection structure. The sliding cooperation between the slider and the sliding groove can ensure that the connecting column and the support column automatically reset after vibration, thereby improving the stability of the seismic sliding bearing device. In addition, the seismic sliding bearing device has the advantages of high integrity and easy installation. It can greatly shorten the overall construction cycle of the steel space frame of large-span stadiums, and its installation does not affect the use of space. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 5 The present invention provides a steel space frame universal seismic sliding support device, including a support column 1, a fixed seat, a slider 4, a circular buckle plate 51 and a connecting column 8.

[0026] The support column 1 is vertically arranged, and a fixed base plate 12 is provided on the top of the support column 1. The two are welded together. The fixed base includes a fixed buckle 3 and a base plate 2. The base plate 2 is fixed to the top of the support column 1 by the fixed buckle 3. The fixed buckle 3 is fixed to the base plate 2 by the fixing bolt, thereby fixing the fixed buckle 3 to the top of the support column 1. The fixed buckle 3 is provided with a mounting hole. The edge of the mounting hole presses against and fixes the edge of the base plate 2. The upper surface of the base plate 2 is provided with a sliding groove. The sliding groove on the upper surface of the base plate 2 protrudes from the mounting hole, so that the slider 4 can be supported in the sliding groove.

[0027] The lower arc-shaped surface of the slider 4 has a flat top structure, and the sliding groove is an arc-shaped groove. In this embodiment, the sliding groove and the lower arc-shaped surface of the slider 4 cooperate with each other, so that the slider 4 and the sliding groove form a sliding connection mechanism. The bottom support plate is used to support the slider 4 and ensure that the bottom support plate and the slider 4 can rotate coaxially. The sliding groove and the lower arc-shaped surface of the slider 4 are both concentric spherical structures.

[0028] The slider 4 is fitted with an upper ring sleeve 5 of a circular structure, and the two are rigidly connected. The circular buckle plate is fastened to the outside of the upper ring sleeve 5. Multiple hydraulic damping cylinders 6 are provided between the inner wall of the circular buckle plate 51 and the outer wall of the upper ring sleeve 5. The hydraulic damping cylinders 6 are arranged around the upper ring sleeve 5 and the slider 4. All hydraulic damping cylinders 6 are perpendicular to the axis of the slider 4, and all hydraulic damping cylinders 6 are on the same plane. The connecting post 8 is connected to the circular buckle plate 51.

[0029] Since all the hydraulic damping cylinders 6 are located in the gap between the circular buckle plate 51 and the upper ring sleeve 5, when the connecting column 8 and the support column 1 vibrate and displace relative to each other, the slider 4 slides relative to the bottom plate in the sliding groove. At this time, the upper ring sleeve 5 fixed to the slider 4 and the circular buckle plate 51 move eccentrically. All the hydraulic damping cylinders 6 generate resistance to this eccentric movement, thereby reducing the vibration and displacement between the connecting column 8 and the support column 1 and generating resistance, thereby damping the connection structure between the connecting column 8 and the support column 1. The sliding cooperation between the slider 4 and the sliding groove can ensure that the connecting column 8 and the support column 1 automatically reset after vibration.

[0030] Preferably, the top of the support column 1 is also provided with at least three limiting columns. In this embodiment, the number of limiting columns is three. All limiting columns are vertically arranged on the top of the support column 1. The three limiting columns are arranged around the slider 4. The slider 4 and the round buckle plate 5 are located between the three limiting columns. The limiting columns can limit the slider 4 and the round buckle plate 5 to prevent the connecting column 8 and the support column 1 from vibrating too much, which would cause the slider 4 to detach from the bottom plate.

[0031] Preferably, the circular buckle plate 51 is further provided with a hemispherical shell 7. The bottom of the hemispherical shell 7 is fixed to the upper surface of the circular buckle plate 51, and the ends of all connecting posts 8 are vertically fixed to the hemispherical shell 7. A reinforcing support member 71 is provided inside the hemispherical shell 7. The reinforcing support member 71 includes a connecting base plate and two semi-circular support plates. The connecting base plate is fixed to the circular buckle plate 51, and the two semi-circular support plates are perpendicularly connected to the connecting base plate and support the inner surface of the hemispherical shell 7. The reinforcing support member 71 is used to improve the connection strength between the hemispherical shell 7 and the circular buckle plate 51 and prevent the hemispherical shell 7 from denting due to excessive force.

[0032] Preferably, the hydraulic damping cylinder 6 includes a cylinder body 61, a piston plate 62, and a piston rod 64. The piston plate 62 is slidably disposed within the cylinder body 61, and the end of the piston rod 64 is connected to the piston plate 62. Both the cylinder body 61 and the piston rod 64 have connecting ends, which are respectively connected to the outer wall of the upper ring sleeve 5 and the inner wall of the circular buckle plate 51. The piston plate 62 is provided with at least two one-way pressure reducing valves 63. Hydraulic oil is injected into the cylinder body 61. The piston plate 62 and the cavity of the two cylinder bodies 61 are separated into two hydraulic chambers. The two one-way pressure reducing valves 63 are connected to the two hydraulic chambers, and the directions of hydraulic oil flow allowed by the two one-way pressure reducing valves 63 are opposite, so that the hydraulic oil in the two hydraulic chambers can flow to each other through the corresponding one-way pressure reducing valves 63. Initially, the piston plate 62 is located in the middle of the cylinder body 61, and the volumes of the two hydraulic chambers are equal. When the connecting column 8 and the support column vibrate and shift relative to each other, the piston rod 64 and the cylinder body 61 shift, causing the piston plate 62 to move within the cylinder body 61. At this time, the volumes and oil pressures of the two hydraulic chambers change, and hydraulic oil flows from one hydraulic chamber to the other. During the flow of hydraulic oil, the one-way pressure reducing valve 63 can generate resistance to the flowing hydraulic oil, thereby slowing down the movement speed of the piston plate 62 and reducing the horizontal impact force when the connecting column 8 and the support column 1 vibrate.

[0033] Preferably, the outer side of the upper ring sleeve 5 and the inner wall of the circular buckle plate 51 are provided with limiting holes. The two connecting ends on the cylinder body 61 and the piston rod 64 are respectively limited in the two limiting holes. The limiting holes are used to ensure that the hydraulic damping cylinder 6 can be accurately installed between the inner wall of the circular buckle plate 51 and the outer wall of the upper ring sleeve 5, so as to ensure that the direction of displacement of the piston rod 64 and the cylinder body 61 of the hydraulic damping cylinder 6 is perpendicular to the axis of the slider 4.

[0034] Preferably, the top of the circular buckle plate 51 is located on the top plate, thus making all the circular buckle plates 51 bottomless cylindrical sleeve structures. The hemispherical shell 7 and the reinforcing support member 71 are both fixed to the top plate. The top of the slider member 4 is provided with a first elastic member, which is a rubber elastic pad 52. A second elastic member, which is a coil spring 53, is also sleeved on the outside of the first elastic member. The first and second elastic members abut against the top plate and the slider member 4 respectively. The first and second elastic members can reduce, and thus reduce, the vertical impact force when the connecting column 8 and the supporting column 1 vibrate.
