Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for steel structure frames, and in particular to vibration reduction supports for prefabricated steel structure frames. Background Technology

[0002] Steel structure frames are characterized by high strength and light weight, capable of withstanding large loads and achieving large spans. For example, some modern sports stadiums use steel structure frames, whose huge domes and column-free spaces can meet the various functional requirements of sports events and large-scale performances. When installing a steel structure frame, its bottom needs to be fixed to multiple bases, and the multiple bases need to be connected to each other to further improve the stability of the bases and the steel structure frame.

[0003] Common vibration damping bearings used in prefabricated steel structure frames only include vibration damping function, which can reduce the vibration of the steel structure frame, but lack the function of interconnecting the bases. This cannot guarantee the stability of multiple bases and the steel structure frame, and it is easy for multiple bases to be installed on the ground separately. In this case, when a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability.

[0004] Therefore, to address the lack of base interconnection functionality in the aforementioned vibration damping supports for prefabricated steel structure frames, a new type of vibration damping support for prefabricated steel structure frames can be designed. This involves rotating an L-shaped connecting plate on the first vibration damping base shell around a pivot point from inside the slot until it is inserted into the connecting slot at the top of the second vibration damping base shell. A limiting rod is then inserted through the through slot and the limiting hole. By rotating a disc using a handle, the disc, via the limiting rod, drives the external threaded head to rotate until it is screwed into the internal threaded groove. This allows the two vibration damping base shells to be connected together via the L-shaped connecting plate, ensuring the stability of multiple bases and the steel structure frame. Utility Model Content

[0005] To overcome the common problem of vibration damping supports used in prefabricated steel structure frames lacking the function of interconnecting bases, which cannot guarantee the stability of multiple bases and steel structure frames, multiple bases are often installed separately on the ground. In this case, when a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability.

[0006] The technical solution of this utility model is as follows: a shock-absorbing support for a prefabricated steel structure frame, including a shock-absorbing bottom shell; it also includes a slot, an L-shaped connecting plate, a limiting hole, a connecting groove, a circular groove, a through groove, an internal thread groove, a limiting rod, and an external thread head. A slot is provided in the middle of the left side of the top of the shock-absorbing bottom shell, and an L-shaped connecting plate is provided in the middle of the inside of the slot. A limiting hole is provided through the top of the front right end of the L-shaped connecting plate. A connecting groove is provided in the middle of the right side of the top of the shock-absorbing bottom shell. A circular groove is provided in the top of the front right end of the shock-absorbing bottom shell corresponding to the position of the connecting groove. A through groove is provided in the center of the rear end of the circular groove. An internal thread groove is provided in the center of the rear side of the connecting groove corresponding to the position of the through groove. A limiting rod is provided in the inside of the through groove, and an external thread head is provided at the rear end of the limiting rod. The external thread head passes through the connecting groove and screws into the inside of the internal thread groove.

[0007] Preferably, the L-shaped connecting plate on the first damping base shell is rotated out from the inside of the slot around the pivot until it is inserted into the connecting slot at the top of the second damping base shell. Then, the limiting rod is passed through the through slot and the limiting hole. The disc is then rotated by the handle, and the disc drives the external thread head to rotate through the limiting rod until the external thread head is screwed into the internal thread groove. In this way, the two damping base shells are connected together by the L-shaped connecting plate, ensuring the stability of multiple bases and the steel structure frame. This solves the problem of common damping supports used in prefabricated steel structure frames, which only have a damping function and can reduce the vibration of the steel structure frame, but lack the function of interconnecting the bases. This cannot guarantee the stability of multiple bases and the steel structure frame, and it is easy for multiple bases to be installed on the ground separately. When a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability.

[0008] Preferably, a disc is provided inside the circular groove, a handle is provided in the middle of the front side of the disc, and the front end of the limiting rod is connected to the rear side of the disc.

[0009] Preferably, a pivot is provided in the middle of the left side of the slot, corresponding to the position of the L-shaped connecting plate, and the pivot is rotatably connected to the L-shaped connecting plate.

[0010] Preferably, a first magnetic block is provided in the middle of the bottom of the slot, and a second magnetic block is provided in the middle of the L-shaped connecting plate on the side close to the first magnetic block, and the first magnetic block and the second magnetic block are magnetically attracted to each other.

[0011] Preferably, a damping groove is provided at the center of the top of the damping base shell, and four spring dampers are provided at equal intervals at the bottom of the damping groove, with a damping plate provided on the top of the spring dampers.

[0012] Preferably, a steel frame connector is provided above the shock-absorbing base shell, and a frame groove is opened at the top center of the steel frame connector. The bottom end of the steel frame connector passes through the shock-absorbing base shell and connects to the top of the shock-absorbing plate.

[0013] Preferably, the bottom of the shock-absorbing base shell is provided with a base plate, and four fixing holes are provided through the four corners of the top of the base plate, and four square grooves are provided at the bottom of the four corners of the shock-absorbing base shell.

[0014] The beneficial effects of this utility model are:

[0015] 1. Rotate the L-shaped connecting plate on the first damping base shell around the pivot from inside the slot until it is inserted into the connecting slot at the top of the second damping base shell. Then, pass the limiting rod through the through slot and the limiting hole. Rotate the disc by the handle. The disc will drive the external thread head to rotate through the limiting rod until the external thread head is screwed into the internal thread groove. In this way, the two damping base shells can be connected together by the L-shaped connecting plate, ensuring the stability of multiple bases and the steel structure frame. This solves the problem of common damping supports used in prefabricated steel structure frames, which only have the function of damping and can reduce the vibration of the steel structure frame, but lack the function of interconnecting the bases. This cannot guarantee the stability of multiple bases and the steel structure frame. It is easy for multiple bases to be installed on the ground individually. When a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a shock-absorbing support for a prefabricated steel structure frame, comprising a shock-absorbing base shell 1; and further comprising a slot 2, an L-shaped connecting plate 3, a limiting hole 4, a connecting groove 5, a circular groove 6, a through groove 7, an internal thread groove 8, a limiting rod 11, and an external thread head 12. A slot 2 is provided in the middle of the left side of the top of the shock-absorbing base shell 1. An L-shaped connecting plate 3 is provided in the middle of the interior of the slot 2. A limiting hole 4 is provided through the top of the front right end of the L-shaped connecting plate 3. A connecting groove 5 is provided in the middle of the right side of the top of the shock-absorbing base shell 1. A circular groove 6 is provided in the top of the front right end of the shock-absorbing base shell 1 corresponding to the position of the connecting groove 5. A through groove 7 is provided in the center of the rear end of the circular groove 6. An internal thread groove 8 is provided in the center of the rear side of the connecting groove 5 corresponding to the position of the through groove 7. A limiting rod 11 is provided inside the through groove 7. An external thread head 12 is provided at the rear end of the limiting rod 11. The external thread head 12 passes through the connecting groove 5 and screws into the interior of the internal thread groove 8, thus attaching the first shock-absorbing base shell 1 to the inside of the connecting groove 8. The L-shaped connecting plate 3 rotates out from the inside of the slot 2 around the rotating shaft 13 until the L-shaped connecting plate 3 on the first shock-absorbing base shell 1 is inserted into the connecting groove 5 at the top of the second shock-absorbing base shell 1. Then, the limiting rod 11 passes through the through groove 7 and the limiting hole 4. Then, the handle 10 rotates the disc 9. The disc 9 drives the external screw head 12 to rotate through the limiting rod 11 until the external screw head 12 is screwed into the internal screw groove 8. In this way, the two shock-absorbing base shells 1 can be connected together by the L-shaped connecting plate 3 to ensure the stability of multiple bases and steel structure frame. This solves the problem of common shock-absorbing supports used for prefabricated steel structure frames, which only have shock absorption function and can reduce the vibration of steel structure frame, but lack the function of interconnecting bases. They cannot guarantee the stability of multiple bases and steel structure frame, and it is easy for multiple bases to be installed on the ground separately. When a single base is damaged and shakes, it will directly drive the steel structure frame to shake, affecting the overall stability.

[0025] Please see Figures 2-6In this embodiment, a damping groove 16 is provided at the center of the top of the damping base shell 1. Four spring dampers 17 are provided at equal intervals at the bottom of the damping groove 16. A damping plate 18 is provided at the top of the spring dampers 17. A steel frame connector 19 is provided above the damping base shell 1. A frame groove 20 is provided at the center of the top of the steel frame connector 19. The bottom end of the steel frame connector 19 passes through the damping base shell 1 and connects to the top of the damping plate 18. A base plate 21 is provided at the bottom of the damping base shell 1. Four fixing holes 22 are provided at the four corners of the top of the base plate 21. Four square grooves 23 are provided at the bottom of the four corners of the damping base shell 1. The damping base shell 1 is fixed to the ground by bolts through the fixing holes 22. Then, the bottom end of the steel frame is inserted into the frame groove 20. The bottom end of the steel frame is fixed to the steel frame connector 19 by bolts. In daily use, the vibration generated by the steel frame is reduced by the spring dampers 17.

[0026] Please see Figures 1-6 In this embodiment, a disc 9 is provided inside the circular groove 6, and a handle 10 is provided in the middle of the front side of the disc 9. The front end of the limiting rod 11 is connected to the rear side of the disc 9. A rotating shaft 13 is provided in the middle of the left side of the groove 2, corresponding to the position of the L-shaped connecting plate 3. The rotating shaft 13 is rotatably connected to the L-shaped connecting plate 3. A first magnetic block 14 is provided in the middle of the bottom end of the groove 2. A second magnetic block 15 is provided in the middle of the side of the L-shaped connecting plate 3 near the first magnetic block 14. The first magnetic block 14 and the second magnetic block 15 are magnetically attracted to each other. After the shock-absorbing base shell 1 is fixed to the ground, the L-shaped connecting plate 3 on the first shock-absorbing base shell 1 is rotated out of the groove 2 around the rotating shaft 13 until... The L-shaped connecting plate 3 on the first shock-absorbing base shell 1 is inserted into the connecting groove 5 at the top of the second shock-absorbing base shell 1. Then, the limiting rod 11 passes through the through groove 7 and the limiting hole 4. Then, the handle 10 rotates the disc 9. The disc 9 drives the external screw head 12 to rotate through the limiting rod 11 until the external screw head 12 is screwed into the internal screw groove 8. In this way, the two shock-absorbing base shells 1 can be connected together by the L-shaped connecting plate 3, which ensures the stability of multiple bases and steel structure frame and realizes the function of interconnecting bases. This prevents multiple bases from being installed on the ground separately. If a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability.

[0027] During operation, the shock-absorbing base shell 1 is fixed to the ground by bolts through the fixing holes 22. Then, the bottom end of the steel structure frame is inserted into the inside of the frame groove 20, and the bottom end of the steel structure frame is fixed to the steel frame connector 19 by bolts. In daily use, the vibration generated by the steel structure frame is reduced by the spring damper 17. After the shock-absorbing base shell 1 is fixed to the ground, the L-shaped connecting plate 3 on the first shock-absorbing base shell 1 is rotated out from the inside of the slot 2 around the rotating shaft 13 until the L-shaped connecting plate 3 on the first shock-absorbing base shell 1 is inserted into the connecting groove 5 at the top of the second shock-absorbing base shell 1. Then, the limiting rod 11 is passed through the through groove 7 and the limiting hole 4. Then, the handle 10 is used to rotate the disc 9. The disc 9 drives the external screw head 12 to rotate through the limiting rod 11 until the external screw head 12 is screwed into the inside of the internal screw groove 8. In this way, the two shock-absorbing base shells 1 can be connected together by the L-shaped connecting plate 3, ensuring the stability of multiple bases and the steel structure frame, and realizing the function of interconnecting the bases.

[0028] Through the above steps, the L-shaped connecting plate 3 on the first damping base shell 1 is rotated out from the inside of the slot 2 around the rotating shaft 13 until the L-shaped connecting plate 3 on the first damping base shell 1 is inserted into the connecting slot 5 at the top of the second damping base shell 1. Then, the limiting rod 11 is passed through the through slot 7 and the limiting hole 4. Then, the handle 10 is used to rotate the disc 9. The disc 9 drives the external screw head 12 to rotate through the limiting rod 11 until the external screw head 12 is screwed into the internal screw groove 8. In this way, the two damping base shells 1 can be connected together by the L-shaped connecting plate 3, which ensures the stability of multiple bases and steel structure frame. This solves the problem that common damping supports used for prefabricated steel structure frames only have the function of damping and can reduce the vibration of the steel structure frame, but lack the function of interconnecting the bases. They cannot guarantee the stability of multiple bases and steel structure frame, and it is easy for multiple bases to be installed on the ground separately. When a single base is damaged and shakes, it will directly cause the steel structure frame to shake, affecting the overall stability.
