Consider this answer impact is bigger, the individual was done for many times adjust, form case study. The individual feels, although the house is of the ferroconcrete, but whole house after catching fire may be burned rise, basically be chimney effect and vitreous disintegrate, the reason is as follows:
One, chimney effect. After fire happening, if build the atrium that existence shares, vertical stroke to ventilated (smoke evacuation) the air channel, stair well place that has similar chimney feature, in the current space that has unobstructed to coping from bottom namely, air (include flue gas) the action that relies on density difference, undertake very quickly diffusing along the passageway, undertake intense heat is exchanged, cause fire to diffuse further.
2, the window outside the building is broken. Its burst ignition is indoor combustible, form bedding face to accumulate stereo combustion. Below action of high difference in temperature, the pane outside architectural is particularly easy disintegrate, below chimney effect effect, high temperature gas, flame is rapid go up string, consummate a building, cause upside to build the furniture inside to burn further.
3, sundry pile up reach other reason. What discard at will is sundry block corridor, make the accessory that fire spreads. Additional, have a share people thinks likelihood heat-insulation layer is influential also. Heat-insulation layer may is blame is flame retardant model expanded plastics, below condition of high temperature combustion, its also produce combustion very quickly. But this won't be main reason, after heat-insulation layer construction is finished, general at construction of the side outside heat-insulation layer mortar of a cement, its inside is brick wall or concrete structure, after construction is finished, isolate with air commonly, won't burn, unless mortar covering layer falls off.
Accordingly, after the building burns, especially lower level builds combustion, personnel should withdraw quickly, start fire control to call the police instantly, the high-pressured squirt of fire engine of have the aid of, put out conflagration in budding condition.
The individual feels, fire flees for his life in the process, elevator hoistway itself is opium chimney, meeting deposit has mephitis system more very much. In the meantime, process of fire rush to deal with an emergency must cut off gas, electric power possibly to wait supply, accordingly, ten million does not flee for his life by elevator, all be not fire control because of general architectural elevator special elevator.
Should make sure corridor is neat more usually.
Is you and my opinion unanimous?
