Abstract

The invention discloses a building. The building is provided with an air supply pipeline for providing breathing air, the pipe wall of the air supply pipeline is provided with an opening in the direction of a hole of the air supply pipeline, all or part of the pipe wall is made of an elastic material, the pipe walls on the two sides of the opening are separated and spaced apart, or the pipe wallson the two sides of the opening are separated and form a crack, the length of the opening is equal to the length of the air supply pipeline or the length of the opening is smaller than the length of the air supply pipeline, the pipe walls on the two sides of the opening are correspondingly connected with a sealing strip I and a sealing strip II, and the sealing strip I and the sealing strip II aremagnetically attracted to play a sealing effect.

Description

technical field [0001] The present application relates to a building provided with an air supply duct capable of supplying breathing air. Background technique [0002] In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. [0003] When a fire breaks out in a building, in order to avoid the damage of smoke to people, the prior art is as follows: an air supply pipeline is arranged inside or outside the structure of the building, and the above-mentioned air supply pipeline is provided with an air outlet at a suitable position on the floor. The air inlet of the air supply pipeline extends to the outside of the building to communicate with the gas outside the building, and the air supply pipeline extends downwards and then extends a certain distance to the outside of the building. Therefore people can inhale the air that is not affected by smog by means of the air outlet, then hold back the breath and advance for a...
