How about Tower Structural Support Chimney?

[Summary description] The tower chimney takes the external tower as the main load-bearing capacity, just like the communication tower, the inner tube of the chimney is fixed on the tower, so it is called "tower-type chimney". Its characteristics are that the floor area is higher than that of the self-supporting chimney, the cost is relatively high (not too much), the safety is high, and the aspect ratio is higher. Then, let's learn about the lower tower chimney!

Then, let's learn about the lower tower chimney!

Tower chimneys need to stand by gravity and therefore require tower support. The advantages are simple and firm, low cost, customizable tower models, more beautiful and practical. Compared with the self-supporting chimney, it is more stable and can definitely be affected by various bad weather more effectively. The effect of the tower chimney is the synergistic effect of the thermal pressure caused by the indoor and outdoor temperature difference and the outdoor wind pressure. The value is proportional to the air density difference caused by the indoor and outdoor temperature difference and the height difference between the air supply and exhaust ports. This shows that the higher the indoor temperature is than the outdoor temperature, the taller the building, and the more obvious the chimney effect. The chimney effect of the civil building only occurs in winter. For a building, it is theoretically considered that the half-height position of the building is the neutralization surface, the room air below the neutralization surface penetrates from the outside, and the room air above the neutralization surface penetrates from the interior.

1. In winter, the air mainly flows into the room from below through various external doors. The straightforward way is to let the building pass through all the doors on the outside. For hall doors, it is particularly necessary to install air curtains on the inside of two doors, revolving doors, door buckets or outer doors as much as possible. Regarding the outer doors of the side passages and underground parking lots, etc., the doors should also be set up in winter, and at least thick curtains should be hung. In winter, the ventilation holes at the top of the elevator shaft must be properly adjusted or closed.

2. For buildings with heating, the indoor temperature of the low-rise part should not be higher than that of the high-rise part.

3. When a fire occurs, not only does the chimney effect occur through various shafts regardless of the season, but also in a small area through the air-conditioning pipeline passing through the ground, or even through the inconspicuous gaps. In contrast, the "Code for Fire Protection Design of High-rise Civil Buildings" (GB50045-1995 has the following explicit provisions).

"For high-rise buildings with a height of less than 100m, every 2-3 floors of cable wells and tube wells should use floor slabs and non-combustible materials equivalent to the fire resistance limit of the floor slabs for fire partitioning. The non-combustible body with the fire resistance limit of the ground shall be used for fire partition." Due to construction defects, bridges, and various gaps formed at the root of the pipeline, it must be compacted with non-combustible materials.

A tower chimney is an extraction tool for removing gases and smoke caused by fire. It is a towering structure that emits smoke into the sky. It can improve combustion conditions and reduce the pollution of smoke to the environment.
