Emergency Rescue – Tower Design
Thread Content
Dear heroes: I was designing and encountered such a condition: A bubble cap tower has a diameter of 2800mm. The tower height originally needs to be 12m. Since it is placed on the floor (third floor), the foundation cannot be solved. Now the foundation needs to be increased by 13.3m. That means I want to make a 25.3m high tower now, and the height of the skirt is 13.3m. Is there such a thing? (Operating pressure -0.05MPa, operating temperature 60 degrees) Thank you!
I think so. If you use ear supports to fix it, I don’t know how many layers your frame has in total. It would be troublesome if it were only three layers. The company that uses it doesn’t agree that the height of the skirt is 13.3m. It’s too wasteful.
It is better to think of a solution based on the form and foundation of the support.
Switch to ear-type supports, which are more economical
25M tower ear holder? Dangerous, need to undergo strength verification
For the ear seat, do I need to make a beam on the floor? Or should I set up a 13m high beam from the ground? Let’s talk about the diameter of 2800. It is a bubble tower, and the weight of the medium operation is estimated to be hundreds of tons! The foundation now needs to be on the ground and the tower needs to be at a height of 13.3m. Tricky! ! !
It is recommended not to use a skirt, but to use ear supports. If the calculation of ear supports is not enough, rigid reinforcement can be considered. Large skirts are only seen in the skirts of pressure relief towers, which are often reinforced by frames.
The tricky thing is the structure. There is no problem. It will definitely not rise on the ground. If it starts on the ground, please let me know. QQ number is 282939699. I hope I can gain more knowledge.
Haha, discuss it with your unit's civil structural engineer. It should be possible to use frame structure support!! Steel frame should be ok.
In the afternoon, I communicated with the process and structure. The structure said that it can be made on the beam, but it cannot be strengthened. The question is how big do I need to make the ear seat for such equipment? It seems that the load that the standard can withstand exceeds the limit. Is it okay to do two laps? Eight! However, in terms of craftsmanship, this is still the case, and there is no need to consider economic issues! Now what I want to ask is, from the perspective of strength, stiffness, stability and other equipment, is there any problem with this? I didn't find any requirements for the height of the skirt on JB4710?
There is no limit to the height of the skirt, it's just too unsightly. I suggest using non-standard ear supports. At least 4 of the 2800 diameter should be used, and the frame structure beams can be made from the ground.
If the factory building is a steel structure, it is recommended to add steel beams and use ear supports.
Nowadays, the cost and safety of the equipment are taken into consideration, and the skirt is used to make it safe and stable. I used to make such tower equipment for a chemical plant in Yixing. The civil construction work was to first make the frame and then carry out other civil construction work after the equipment was in place. This post was last edited by lghui on 2008-4-25 21:47 ]
It should be possible. This is what our company does. The tower is 15m high and the floors are 6m high. The tower is mounted on the third and fourth floors with ear-type supports, which has a diameter of 1400. The load-bearing issue was taken into consideration during the civil construction. However, the structure said it could be built on beams, but it was not possible. There must be a written conclusion. This is a big issue involving safety. The first principle of our design is safety and reliability, and no sloppiness is allowed. Don’t!
If the factory building is a steel structure, it is recommended to add steel beams, or skirts can be used. The skirt is sitting on the beam.
A reinforced concrete foundation of 13.3 meters was built directly from the civil engineering department and the tower was placed on the concrete foundation.
The calculation of the ear seat is definitely the same. If you can't think of a solution based on the basics, you can only use the ear support form with a rigid ring. For details on the calculation of rigid rings, see HG20582
First: I’ve never seen a 13.3m skirt, and it’s not economical either. ； second: Use cement foundation + skirt ； third: With frame + ear mount ； It is necessary to calculate the load-bearing capacity of the frame and ear seats, and the local load of the shell at the ear seats. ；
