Description

Technical Field

[0001] This utility model relates to the field of steel structure support technology, and in particular to a steel structure sliding support. Background Technology

[0002] Nowadays, small and medium-sized steel structure buildings are increasingly pursuing architectural innovation and have complex shapes. Seismic joints cannot be broken between the small units to meet the needs of building function and facade. The best solution is to set sliding bearings, which not only meet the building requirements, but also allow each small unit to bear the force independently under seismic action, without the seismic force acting on each other.

[0003] Although an existing type of steel structure sliding bearing has the safety feature of preventing steel beams from slipping.

[0004] However, this type of steel structure sliding bearing has the following disadvantages: traditional bearings mostly use a single spring or rubber pad, which has limited shock absorption effect and is difficult to cope with the multi-directional impact of complex loads, which can easily lead to structural resonance or local damage. In addition, although some bearings allow a certain amount of sliding, they lack effective guiding constraints and are prone to bearing jamming or steel structure instability due to displacement, especially under cyclic loads where the risk is even higher. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a steel structure sliding bearing that is highly practical and has a simple structure that can be operated easily. It solves the problems mentioned in the background art, where traditional bearings mostly use a single spring or rubber pad, which have limited shock absorption effect, are difficult to cope with multi-directional impacts of complex loads, and are prone to structural resonance or local damage. In addition, although some bearings allow a certain amount of sliding, they lack effective guiding constraints and are prone to jamming of the bearing or instability of the steel structure due to displacement, especially under cyclic loads where the risk is even higher.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure sliding support, comprising a fixed plate, a cavity plate fixedly installed in the middle of the top surface of the fixed plate, a polystyrene filler inside the cavity plate, a cavity rod fixedly installed in the middle of the top surface of the polystyrene filler, a sliding groove on both sides of the cavity rod, a buffer rod slidably connected inside the sliding groove, a square block fixedly installed on both sides of the buffer rod, a buffer assembly fixedly installed at the bottom of the square block, a crossbar fixedly installed in the middle of the top surface of the buffer rod, guide rods fixedly installed on both sides of the bottom of the crossbar, and one side of the guide rod surface slidably connected to both sides of the outer surface of the cavity rod.

[0007] Optionally, a slot frame is fixedly installed at the bottom of the fixing plate, and connecting bolts are threaded through both sides of the slot frame.

[0008] Optionally, the surface of the connecting bolt is threaded with a shock-absorbing pad, which is rectangular in shape.

[0009] Optionally, a protective cover is fixedly installed at the edge of the chute, and an anti-oxidation film is attached to the outer surface of the protective cover.

[0010] Optionally, the outer surface of the fixing plate is coated with an anti-oxidation coating, and both sides of the outer surface of the cavity rod are provided with sliding grooves, the inside of which is slidably connected to one side of the guide rod.

[0011] Optionally, the buffer assembly includes a shock-absorbing spring fixedly connected to the center of the bottom surface of the square block, and a damping telescopic rod is sleeved inside the shock-absorbing spring.

[0012] This utility model provides a steel structure sliding support, which has the following beneficial effects: 1. This steel structure sliding support, through the setting of cavity plate, polystyrene filler and buffer rod, during the use of steel structure, its cavity rod transmits the pressure downward, so that the pressure is transmitted to the interior of polystyrene filler, and then the polystyrene filler can improve the stability and isolation and shock absorption of cavity rod and buffer rod.

[0013] 2. This steel structure sliding support, through the setting of buffer components, buffer rods and cavity rods, when the buffer rod is under pressure, its buffer rod moves downward along the cavity rod, causing the square block to drive the shock-absorbing spring to contract. Subsequently, the damping telescopic rod can absorb the shock of the buffer rod. Then, the guide rod moves downward with the buffer rod to assist in the movement, thereby improving the shock absorption of the buffer rod and reducing the occurrence of accidental displacement of the buffer rod.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution for a steel structure sliding support: a steel structure sliding support includes a fixed plate 1, a cavity plate 2 is fixedly installed in the middle of the top surface of the fixed plate 1, a polystyrene filler 3 is provided inside the cavity plate 2, and a cavity rod 4 is fixedly installed in the middle of the top surface of the polystyrene filler 3. When installing the sliding support, align the slot frame 10 with the center of the installation foundation, and initially connect the fixing plate 1 to the foundation using the connecting bolt 11. Insert the shock-absorbing pad 12 at the contact point between the connecting bolt 11 and the fixing plate 1, adjust the level of the fixing plate 1, and tighten the connecting bolt 11 to ensure that the fixing plate 1 is tightly fitted to the foundation and has the foundation's shock-absorbing capacity. Then, place the cavity plate 2 horizontally in the center of the top surface of the fixing plate 1, so that the bottom of the cavity plate 2 is in complete contact with the top surface of the fixing plate 1. Subsequently, when the steel structure transmits vertical loads to the crossbar 8, the pressure is transmitted to the buffer through the crossbar 8. Rod 5 and buffer rod 5 move downward along the groove of the cavity rod 4; at this time, the square block 6 compresses the shock-absorbing spring 71 at the bottom, and the damping telescopic rod 72 extends and retracts synchronously. The shock energy is absorbed by the elastic deformation of the shock-absorbing spring 71, and the damping effect suppresses the high-frequency vibration of the shock-absorbing spring 71, thus reducing the vibration transmission together; at the same time, the guide rod 9 slides along the sliding groove, constraining the buffer rod 5 to move only in the vertical direction, avoiding structural instability caused by displacement; the polystyrene filler 3 in the cavity plate 2 undergoes slight elastic deformation under pressure, further dispersing the load and buffering local impacts, thus improving the overall stability; Please see Figures 1 to 4 Both sides of the hollow rod 4 are provided with sliding grooves, and a buffer rod 5 is slidably connected inside the sliding groove. Both sides of the buffer rod 5 are fixedly installed with square blocks 6. A buffer assembly 7 is fixedly installed at the bottom of the square blocks 6. A protective cover 13 is fixedly installed at the edge of the sliding groove. An anti-oxidation film is attached to the outer surface of the protective cover 13. The buffer assembly 7 includes a shock-absorbing spring 71 fixedly connected to the middle of the bottom surface of the square block 6. A damping telescopic rod 72 is sleeved inside the shock-absorbing spring 71. With the arrangement of buffer assembly 7, buffer rod 5 and cavity rod 4, when the buffer rod 5 is subjected to pressure, the buffer rod 5 moves downward along the cavity rod 4, causing the square block 6 to drive the shock-absorbing spring 71 to contract. Subsequently, the damping telescopic rod 72 can dampen the buffer rod 5. Then, the guide rod 9 moves downward with the buffer rod 5 to assist in the movement, thereby improving the shock absorption of the buffer rod 5 and reducing the occurrence of accidental displacement of the buffer rod 5.

[0018] Please see Figures 1 to 4A crossbar 8 is fixedly installed in the middle of the top surface of the buffer rod 5. Guide rods 9 are fixedly installed on both sides of the bottom of the crossbar 8. One side of the surface of the guide rod 9 is slidably connected to both sides of the outer surface of the cavity rod 4. An anti-oxidation coating is applied to the outer surface of the fixing plate 1. A sliding groove is opened on both sides of the outer surface of the cavity rod 4. The inside of the sliding groove is slidably connected to one side of the guide rod 9. With the guide rod 9 and the crossbar 8 in place, when the buffer rod 5 is subjected to pressure and moves downward, the guide rod 9 can assist the buffer rod 5 to slide downward along the cavity rod 4, thereby reducing the left and right swaying of the buffer rod 5.

[0019] Please see Figures 1 to 4 A slot frame 10 is fixedly installed at the bottom of the fixing plate 1. Connecting bolts 11 are threaded through both sides of the slot frame 10. Shock-absorbing pads 12 are threadedly connected to the surface of the connecting bolts 11. The shock-absorbing pads 12 are rectangular. With the installation of the slot frame 10 and the shock-absorbing pad 12, when personnel need to install the fixing plate 1, they can place the slot frame 10 at the bottom of the designated equipment, so that the slot frame 10 is snapped onto the outer surface of the designated foundation. Then, the shock-absorbing pad 12 is used to reduce the pressure on the fixing plate 1, thereby improving the stability and shock absorption of the slot frame 10.

[0020] In this invention, the working steps of the device are as follows: When installing the sliding support, align the slot frame 10 with the center of the installation foundation, and initially connect the fixing plate 1 to the foundation using the connecting bolt 11. Insert the shock-absorbing pad 12 at the contact point between the connecting bolt 11 and the fixing plate 1, adjust the level of the fixing plate 1, and tighten the connecting bolt 11 to ensure that the fixing plate 1 is tightly fitted to the foundation and has the foundation's shock-absorbing capacity. Then, place the cavity plate 2 horizontally in the center of the top surface of the fixing plate 1, so that the bottom of the cavity plate 2 is in complete contact with the top surface of the fixing plate 1. Subsequently, when the steel structure transmits vertical loads to the crossbar 8, the pressure is transmitted to the buffer through the crossbar 8. Rod 5 and buffer rod 5 move downward along the groove of the cavity rod 4; at this time, the square block 6 compresses the bottom shock-absorbing spring 71, and the damping telescopic rod 72 extends and retracts synchronously. The shock-absorbing spring 71 absorbs the impact energy through elastic deformation, and the damping effect suppresses the high-frequency vibration of the shock-absorbing spring 71, thus reducing the vibration transmission together; at the same time, the guide rod 9 slides along the auxiliary sliding groove, constraining the buffer rod 5 to move only in the vertical direction, avoiding structural instability caused by displacement; the polystyrene filler 3 in the cavity plate 2 undergoes slight elastic deformation under pressure, further dispersing the load and buffering local impacts, thus improving the overall stability.
