Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a seismic-resistant node support for steel structure engineering. Background Technology

[0002] During the construction process, pipelines are often laid to transport tap water, fire water, and natural gas. The pipelines are installed and fixed using node support structures. When an earthquake occurs, the buffer mechanism set in the node support can effectively reduce the damage to the pipelines caused by the earthquake, thereby reducing casualties and property losses.

[0003] Existing node support structures use spring mechanisms to buffer and protect against tension and vibration when the support is subjected to tension. However, the spring mechanism is prone to metal fatigue when subjected to stress for a long time, which reduces the buffering effect and affects the protection of the pipeline. Therefore, we propose a seismic node support for steel structure engineering. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a seismic-resistant node support for steel structure engineering.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seismic-resistant node support for steel structure engineering, comprising a conveying pipe, a base frame, a clamping frame, a clamping pad, and a ceiling frame. A buffer assembly is provided between the base frame and the ceiling frame. The buffer assembly consists of a supporting column and a buffer shaft. The top of the supporting column is assembled with the outside of the ceiling frame via a snap-fit ​​mechanism. The bottom of the buffer shaft is assembled and connected with the top of the base frame. An internal groove is provided inside the supporting column, and the buffer shaft is located inside the internal groove. A limiting cavity is provided inside the internal groove. The upper end of the buffer shaft is limited and engaged with the inside of the limiting cavity via a limiting seat. A buffer spring is provided inside the limiting cavity and is fixedly connected and engaged with the limiting seat. An airbag with internal air pressure is sleeved on the outside of the buffer shaft.

[0006] Preferably, when the conveying pipe vibrates and pulls the buffer shaft through the base frame, the limiting seat at the upper end of the buffer shaft is in a compressed buffer state through the buffer airbag.

[0007] Preferably, when the conveying pipe vibrates and pulls the buffer shaft through the base frame, the limiting seat at the upper end of the buffer shaft is in a pulling auxiliary buffer state through the buffer spring.

[0008] Preferably, a protective pad is provided above the clamping frame, and a sleeve groove is provided inside the clamping frame. One set of clamping frames is slidably fitted inside the base frame through the sleeve groove. One set of clamping frames is provided with a screw groove inside. A screw shaft that is threadedly connected to the screw groove is installed on one side of another set of clamping frames. A screw sleeve is fitted on the external thread of the screw shaft, and a dial is installed around the screw sleeve.

[0009] Preferably, after the two sets of clamping frames are clamped to the outside of the conveying pipe by clamping pads, when the screw sleeve is adjusted by the pivot to align with one side of one set of clamping frames, the two sets of clamping frames are in a clamping and fixed state to the outside of the conveying pipe by clamping pads.

[0010] This utility model provides a seismic-resistant joint support for steel structure engineering. It has the following beneficial effects:

[0011] 1. This is a seismic-resistant node support for steel structure engineering. In this paper, the conveying pipe can be clamped and fixed by the base frame and the clamping frame. The base frame is supported by a buffer assembly and the ceiling frame. The buffer assembly is connected by a support column and a buffer shaft. When the conveying pipe vibrates due to external factors, the conveying pipe can be pulled downward by the buffer shaft through the base frame. The upper end of the buffer shaft can be squeezed by the limit seat to compress the buffer airbag inside the support column. The buffer airbag is filled with air pressure. In this way, the buffer shaft can be deformed and buffered by the air pressure inside the buffer airbag, avoiding the direct fixing stress of the conveying pipe itself, which would cause the traditional whole support to fall off. The limit seat at the upper end of the buffer shaft can be assisted by the buffer spring for elastic pulling and buffering, which improves the buffering effect of the buffer shaft on the conveying pipe itself, thereby improving the protection effect of the conveying pipe.

[0012] 2. This type of seismic joint support for steel structure engineering, after the conveying pipe is placed on the protective pad on the base frame, two sets of clamping frames can clamp the outside of the conveying pipe. When clamping conveying pipes of different diameters, one set of clamping frames can be slidably adjusted outside the base frame to adapt to the different diameters of the conveying pipes for clamping and fitting. By rotating the pivot shaft to adjust the screw sleeve to connect with one side of the clamping frame, the clamping stability of the two sets of clamping frames is ensured, thereby achieving the effect of multi-functional clamping of the conveying pipe.

[0023] Example: A seismic-resistant joint support for steel structure engineering, such as Figures 1-5As shown, the system includes a conveying pipe 1, a base frame 2, a clamping frame 3, a clamping pad 4, and a ceiling frame 5. A buffer assembly 6 is provided between the base frame 2 and the ceiling frame 5. The buffer assembly 6 consists of a supporting column 8 and a buffer shaft 10. The top of the supporting column 8 is assembled with the outside of the ceiling frame 5 via a snap-fit ​​mechanism 7. The bottom of the buffer shaft 10 is assembled and connected with the top of the base frame 2. An internal groove 9 is provided inside the supporting column 8, and the buffer shaft 10 is located inside the internal groove 9. A limiting cavity 11 is provided inside the internal groove 9. The upper end of the buffer shaft 10 is limited and engaged with the inside of the limiting cavity 11 via a limiting seat 12. The cavity 11 is equipped with a buffer spring 13 that is fixedly connected to the limit seat 12. The buffer shaft 10 is fitted with a buffer airbag 14 with internal air pressure. A protective pad 15 is provided above the clamping frame 3. The clamping frame 3 has a sleeve groove 16 inside. One set of clamping frames 3 is slidably fitted to the outside of the base frame 2 through the sleeve groove 16. One set of clamping frames 3 has a screw groove 17 inside. The other set of clamping frames 3 has a screw shaft 18 threadedly connected to the screw groove 17 on one side. The screw shaft 18 has a screw sleeve 19 threaded on its external thread. A dial 20 is installed around the screw sleeve 19.

[0024] Furthermore, when the conveying pipe 1 vibrates and pulls the buffer shaft 10 through the base frame 2, the limiting seat 12 at the upper end of the buffer shaft 10 is in a compressed buffer state through the buffer airbag 14.

[0025] Furthermore, when the conveying pipe 1 generates vibration and pulls the buffer shaft 10 through the base frame 2, the limiting seat 12 at the upper end of the buffer shaft 10 is in a pulling auxiliary buffer state through the buffer spring 13.

[0026] Furthermore, after the two sets of clamping frames 3 are clamped to the outside of the conveying pipe 1 by the clamping pads 4, when the adjusting screw sleeve 19 of the pivot shaft 20 is connected to one side of one set of clamping frames 3, the two sets of clamping frames 3 are clamped and fixed to the outside of the conveying pipe 1 by the clamping pads 4.

[0027] The working principle of this utility model:

[0028] The conveying pipe 1 can be clamped and fixed by the base frame 2 and the clamping frame 3. The base frame 2 is supported by the buffer assembly 6 and the ceiling frame 5. The buffer assembly 6 is connected by the support column 8 and the buffer shaft 10. When the conveying pipe 1 vibrates due to external factors, the conveying pipe 1 can be pulled downward by the base frame 2 to the buffer shaft 10. The upper end of the buffer shaft 10 can be squeezed by the limiting seat 12 to the buffer airbag 14 inside the support column 8. The buffer airbag 14 is filled with air pressure. In this way, the buffer shaft 10 can be deformed and buffered by the air pressure inside the buffer airbag 14, avoiding the direct fixing stress of the conveying pipe 1 and causing the traditional whole support to fall off. The limiting seat 12 at the upper end of the buffer shaft 10 can be assisted by the buffer spring 13 to provide elastic pull buffering, thereby improving the buffering effect of the buffer shaft 10 on the conveying pipe 1 itself.
