Steel beam with vibration-damping adjustment structure

Abstract

This utility model relates to the field of building engineering technology and discloses a steel beam with a vibration damping and adjustment structure, including two support columns. A steel beam is fixedly connected to the top of the two support columns on adjacent sides. Turnbuckles are installed on adjacent sides of each support column, and tensioning bars are fixedly connected to adjacent ends of each turnbuckle. Rectangular steel pipes are connected to the bottom left and right sides of the steel beam via vibration damping components for vibration damping. The inner wall of the rectangular steel pipe is slidably connected to the outer wall of the tensioning bar. In this utility model, the force is transmitted through a connecting steel plate to a vibration damping pad, and then to the rectangular steel pipe. The vibration damping pad, made of butyl rubber, possesses excellent damping performance due to the high hysteresis of its molecular chain, thus mitigating the force. Finally, the force is transmitted through the rectangular steel pipe to the tensioning bar for release, preventing resonance of the steel beam caused by vibrations from vibrating equipment on the beam.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a steel beam with a vibration reduction and adjustment structure. Background Technology

[0002] With the rapid development of industry, the scale and complexity of industrial production are constantly increasing, placing higher demands on the utilization of building space. As a result, industrial buildings are gradually shifting from traditional single-story industrial plants to multi-story or high-rise steel-framed plants. On the one hand, land resources are becoming increasingly scarce, and urban land available for industrial development is becoming increasingly limited. Multi-story or high-rise steel-framed plants can provide more usable space on limited land, greatly improving land utilization and meeting the needs of industrial enterprises to expand production scale. On the other hand, modern industrial production is gradually developing towards refinement, intelligence, and lightweighting. Many production equipment are no longer as bulky and heavy as in the past, reducing the requirements for ground bearing capacity and making them more suitable for placement on the floors of multi-story or high-rise plants. At the same time, the layout of multi-story or high-rise plants facilitates the three-dimensional and automated production process. Different production stages can be arranged in layers according to process requirements, reducing the horizontal transportation distance of materials and improving production efficiency. Furthermore, high-rise steel-framed plants have better seismic performance and load-bearing capacity, enabling them to adapt to complex geological conditions and diverse production needs. This architectural style can also integrate more functions, such as research and development, office, and warehousing, forming a comprehensive industrial production space that provides greater flexibility and convenience for enterprise development.

[0003] However, during operation, production equipment often causes vibrations to the surrounding steel beams, sometimes even resonating with them. This not only affects the precision of the equipment but also severely impacts structural stability, posing significant safety hazards and causing discomfort to workers within the factory. In practice, increasing the cross-section of beams and columns to improve stiffness is often the solution, but this is ineffective, and significant vibrations still occur during actual production. Therefore, reducing structural vibration is a crucial problem that those skilled in the art need to address. To this end, this application proposes a steel beam with a vibration-damping and adjustment structure to address this technical problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel beam with a vibration damping and adjustment structure. The vibration is transmitted through a connecting steel plate to a damping pad and then to a rectangular steel pipe. The damping pad, made of butyl rubber, has excellent damping performance due to the high hysteresis of its molecular chain, which reduces the force. Finally, the force is transmitted through the rectangular steel pipe to the tensioning steel bar to release the force, thus avoiding resonance caused by vibrations from vibrating equipment on the beam.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A steel beam with a vibration damping and adjustment structure includes two support columns. The top of the two support columns is fixedly connected to the steel beam on the side closest to each other. Turnbuckles are installed on the side closest to each support column. Tensioning bars are fixedly connected to the end of the two turnbuckles on the side closest to each other. Rectangular steel pipes are connected to the bottom left and right sides of the steel beam through vibration damping components for vibration damping. The inner wall of the rectangular steel pipe is slidably connected to the outer wall of the tensioning bars.

[0007] Furthermore, the shock absorption assembly includes connecting steel plates fixedly connected to the bottom of the left and right sides of the steel beam and the top of the rectangular steel pipe, and shock absorption pads are fixedly connected to the side of the connecting steel plates near the bottom and top.

[0008] Furthermore, four mounting bolts are threaded onto the side of the connecting steel plate near the bottom and top.

[0009] Furthermore, the shock-absorbing pad is made from butyl rubber.

[0010] Furthermore, flange bolts are fixedly connected to the adjacent ends of the two tensioning steel bars.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the force is transmitted from the connecting steel plate to the shock-absorbing pad and then to the rectangular steel pipe. The shock-absorbing pad, made of butyl rubber, has excellent damping performance due to the high hysteresis of its molecular chain, which reduces the force. Finally, the force is transmitted to the tensioned steel bar through the rectangular steel pipe to release the force, thus avoiding the resonance effect of the steel beam caused by the vibration of the vibrating equipment on the beam.

[0013] 2. In this utility model, the force generated by equipment vibration is released through layer-by-layer transmission and release, which will not cause the steel beam to resonate and affect the operation of the equipment, thereby ensuring the precise operation of the equipment.

The force is transmitted from plate 9 to damping pad 7 and then to rectangular steel pipe 3; the force is mitigated by damping pad 7; four mounting bolts 8 are threadedly connected to the bottom and top of the connecting steel plate 9 on the side close to each other. The damping pad 7 is made of butyl rubber, and the high hysteresis of the molecular chain gives it excellent damping performance, which can effectively isolate vibration and absorb impact energy; flange bolts 5 are fixedly connected to the two tensioning steel bars 4 at their close ends, and the inner wall of the rectangular steel pipe 3 is slidably connected to the outer wall of the tensioning steel bar 4. The force generated by the vibration is transmitted to the tensioning steel bar 4 through the rectangular steel pipe 3 to release the force.

Turnbuckles 6 are installed on the two support columns 1 to connect the tensioning steel bars 4. The two tensioning steel bars 4 are connected by flange bolts 5.
