Description

Three-dimensional smoke exhaust system of underground garage

Technical Field

The utility model relates to the technical field of arrangement of smoke exhaust pipes of underground garage, in particular to a three-dimensional smoke exhaust system of an underground garage.

Background

The garage is a building for parking and storing cars, and the underground garage is a garage in which the indoor terrace of the garage is lower than the outdoor terrace by more than half of the net height of the garage.

According to the requirements of 'design fire prevention standards of garage, garage repair and parking lot' and 'technical standards of building smoke prevention and exhaust systems', an underground garage is required to be provided with a mechanical exhaust system. Because the flue gas exhaust pipe is bulky, the height of the main pipe can reach about 400mm, and the flue gas exhaust pipe of the single-layer underground garage needs to occupy about 600mm of layer height in consideration of actual conditions that installation space and a lower spray head of a spray system are added. Because the occupied area of the existing underground garage smoke exhaust structure is large, the whole volume of the underground garage is correspondingly increased.

In summary, we propose a three-dimensional smoke exhaust system for an underground garage to solve the above technical problems.
