A beam-column shock-absorbing structure

Abstract

The present invention discloses a beam-column shock-absorbing structure, which belongs to the technical field of beams and columns of steel structure buildings. The structure includes a crossbeam and a shock-absorbing component B. The crossbeam is arranged on two supporting columns arranged side by side. The shock-absorbing component B is located on the lower side of the crossbeam and between the two supporting columns, and the shock-absorbing component B contacts the bottom surface of the crossbeam. Both ends of the shock-absorbing component B are rotatably connected to the adjacent supporting columns through two connecting rods. When the equipment installed on the crossbeam transmits vibration to the crossbeam, the crossbeam transmits the vibration to the arc plate, and the vibration of the crossbeam is damped through the arc plate. The arc plate further transmits the vibration to the connecting rod, and the connecting rod is damped through the spring, so as to avoid resonance between the crossbeam and the equipment, thereby avoiding bending or even breaking of the crossbeam. In addition, the supporting column provides support for the middle part of the crossbeam through the fixing rod, the connecting rod, the round rod and the arc plate, which helps to improve the rigidity of the crossbeam and extend the service life of the crossbeam.

Description

Technical Field

[0001] The invention relates to a beam-column shock-absorbing structure, belonging to the technical field of beams and columns of steel structure buildings. Background Art

[0002] Steel structure buildings have the characteristics of high strength, light weight, fast construction speed, good earthquake resistance and high degree of industrialization. In modern factories, some large equipment needs to be fixed on steel structure beams, and the gravity of the equipment itself and the vibration generated by the operation of the equipment will cause the beams to bend or even break. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a beam-column shock-absorbing structure.

[0004] The present invention is achieved through the following technical solutions:

[0005] A beam-column shock-absorbing structure comprises a crossbeam and a shock-absorbing assembly B, wherein the crossbeam is arranged on two supporting columns arranged side by side, the shock-absorbing assembly B is located on the lower side of the crossbeam and between the two supporting columns, and the shock-absorbing assembly B contacts the bottom surface of the crossbeam, and both ends of the shock-absorbing assembly B are rotatably connected to the adjacent supporting columns through two connecting rods.

[0006] The vibration reduction component B is an arc-shaped plate, and the outer circumferential surface of the arc-shaped plate abuts against the bottom surface of the crossbeam.

[0007] Round rods are provided at both ends of the arc-shaped plate, and the length of the round rods is greater than the width of the arc-shaped plate.

[0008] Both ends of the round rod can be detachably connected with the limiting plates.

[0009] A fixing rod is provided on the support column above the vibration reduction assembly B, and the fixing rod passes through the support column.

[0010] One end of the connecting rod is rotatably connected to the round rod, and the other end is rotatably connected to the fixed rod.

[0011] The support column is provided with a vibration reduction assembly A on the upper and lower sides of the connecting rod.

[0012] The vibration reduction assembly A comprises an L-shaped mounting plate and an elastic member. The L-shaped mounting plate is arranged on the support column. One end of the elastic member is connected to the L-shaped mounting plate, and the other end is connected to the connecting rod.

[0013] The elastic member is a spring.

[0014] The center line of the spring is perpendicular to and intersects with the center line of the connecting rod.

[0015] The beneficial effect of the present invention is that when the equipment installed on the crossbeam transmits vibration to the crossbeam, the crossbeam transmits vibration to the arc plate, and the vibration of the crossbeam is reduced by the arc plate. The arc plate further transmits vibration to the connecting rod, and the connecting rod is reduced by the spring, so as to avoid resonance between the crossbeam and the equipment, thereby avoiding bending or even breaking of the crossbeam. In addition, the support column provides support for the middle part of the crossbeam through the fixed rod, the connecting rod, the round rod and the arc plate, which helps to improve the rigidity of the crossbeam and extend the service life of the crossbeam.

[0019] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0020] like Figure 1 and Figure 2 As shown, a beam-column shock-absorbing structure of the present invention comprises a crossbeam 2 and a shock-absorbing assembly B6, wherein the crossbeam 2 is mounted on two support columns 1 arranged side by side, the shock-absorbing assembly B6 is located at the lower side of the crossbeam 2 and between the two support columns 1, and the shock-absorbing assembly B6 contacts the bottom surface of the crossbeam 2, and both ends of the shock-absorbing assembly B6 are rotatably connected to the adjacent support columns 1 through two connecting rods 5. The crossbeam 2 is subjected to vibration reduction by the shock-absorbing assembly B6.

[0021] The vibration reduction component B6 is an arc plate 60, the outer circumferential surface of which is against the bottom surface of the beam 2. When in use, the arc plate 60 has good elasticity and the ability to recover to its original shape. When the beam 2 vibrates, the arc plate 60 continuously deforms, stretches, and recovers to its original shape. The arc plate 60 reduces vibration, thereby preventing the beam 2 from resonating with the equipment mounted on the beam 2.

[0022] Round rods 61 are welded to both ends of the arc plate 60, and the length of the round rods 61 is greater than the width of the arc plate 60, so that the round rods 61 and the connecting rods 5 can be rotatably connected.

[0023] Both ends of the round rod 61 are detachably connected to the limiting plates 62 to prevent the connecting rod 5 from being separated from the round rod 61 .

[0024] A fixing rod 3 is installed on the support column 1 above the vibration reduction assembly B6, and the fixing rod 3 penetrates the support column 1. The fixing rod 3 penetrates the support column 1 so that the fixing rod 3 can be firmly fixed on the support column 1.

[0025] One end of the connecting rod 5 is rotatably connected to the round rod 61 , and the other end is rotatably connected to the fixing rod 3 .

[0026] The support column 1 is provided with a vibration reduction assembly A4 on both the upper and lower sides of the connecting rod 5 .

[0027] The vibration reduction assembly A4 includes an L-shaped mounting plate and an elastic member. The L-shaped mounting plate is fixedly mounted on the support column 1 . One end of the elastic member is connected to the L-shaped mounting plate, and the other end is connected to the connecting rod 5 .

[0028] The elastic member is a spring. The spring is used to reduce vibration of the connecting rod 5, which helps to make the connecting rod 5 swing smoothly.

[0029] The center line of the spring is perpendicular to and intersects with the center line of the connecting rod 5 .

[0030] The beam-column shock-absorbing structure of the present invention has the following working principle or working process:

[0031] When the equipment installed on the beam 2 transmits vibration to the beam 2, the beam 2 transmits vibration to the arc plate 60, and the arc plate 60 reduces vibration of the beam 2. The arc plate 60 further transmits vibration to the connecting rod 5, and the connecting rod 5 is reduced by the spring to avoid resonance between the beam 2 and the equipment, thereby preventing the beam 2 from bending or even breaking. In addition, the support column 1 provides support for the middle part of the beam 2 through the fixing rod 3, the connecting rod 5, the round rod 61 and the arc plate 60, which helps to improve the rigidity of the beam 2 and extend the service life of the beam 2.
