Building

Abstract

The invention discloses a building which is provided with an air supply pipeline; a linear opening is formed in a pipe wall of the air supply pipeline in the extension direction of the air supply pipeline; the opening penetrates through the pipe wall of the air supply pipeline or the opening is closed to so as to obtain a liner gap; the pipe wall is wholly or partly made of elastic materials; theopening can be opened under the action of external force and can be closed under the action of elastic force of the pipe wall after the external force is withdrawn; the opening can contain a pluralityof ventilating pipes at the same time; the ventilating pipes can move in the opening in the extension direction of the air supply pipeline; after the ventilating pipes are inserted into the air supply pipeline, the parts, at the side edge of the opening, of the pipe wall of the air supply pipeline, or sealing components connected with the parts, at the side edge of the opening, of the pipe wall of the air supply pipeline can wrap the ventilating pipes; and an air inlet of the air supply pipeline extends to outer side of the building and is connected with air purification equipment or positivepressure air supply equipment.

Description

technical field [0001] This application relates to a building. Background technique [0002] There are many combustible decorations, chemical fiber carpets and furniture filled with foam plastics in modern buildings. These combustibles will produce a lot of toxic smoke and heat during combustion, and consume a lot of oxygen. In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. According to the statistics of the causes of casualties in fires in the UK, the death toll due to suffocation due to carbon monoxide poisoning or other toxic smoke generally accounts for 40% to 50% of the total death toll, and among the people who were burned to death, most of them were poisoned first. Burned to death after asphyxiation. When a fire breaks out, because combustion consumes a lot of oxygen, the oxygen concentration in the air drops significantly. If people stay in this hypoxic environment for a long time, they will cause...

Problems solved by technology

Such a technical measure has the disadvantage of being inconvenient to use the air outlet, and cannot continuously inhale fresh air, which will cause a great psychological burden to the escaped personnel and easily cause the risk of scrambling for the air outlet
