Description
Technical Field
The utility model belongs to the building field, more specifically relates to a building unit and contain car of this building unit medium and high-rise residence upstairs.
Background
Going upstairs of the automobile is a main characteristic of the fourth generation middle and high-rise residential building, namely, each layer of the residential building is provided with a garage, and the automobile can be driven to a door, but the combination of the automobile garage and the common middle and high-rise residential building greatly increases the complexity in fire fighting, thereby bringing the challenge in fire fighting engineering.
The fire of a medium-high building generally has the following characteristics: (1) the combustible is more, and the fire load is large. With the development of national economy and social progress, the living standard of people is continuously improved, and the grade of home decoration is higher and higher. In residential buildings, a large amount of household appliances, clothes, soft cushion or solid wood furniture and a large amount of flammable materials are stacked in limited space, so that the load of fire in the residential buildings is large, and once a fire occurs, the fire can be fiercely burnt. (2) The fire spread rapidly. If the fire separation or fire treatment is not good, a vertical chimney effect is easily formed when a fire disaster occurs, and the vertical shaft is a way for rapidly spreading the fire behavior. It has been determined that the vertical propagation of a fire is about 5 times faster than the horizontal propagation. Secondly, wind has a great influence on high-rise building fire. Since wind speed increases as the height of the building increases. Therefore, the fire spreading speed of the high-rise residential building is high no matter the high-rise residential building is inside or outside the building. (3) The difficulty of the rescue is high. The high-rise residential building has higher height and large space volume, and once the high-rise residential building catches fire, the fire fighting difficulty is higher. (4) Evacuation is difficult. The high-rise residential buildings have a large number of floors and long vertical distance, so that the time for evacuating to the ground or other safe places is long; secondly, people in the residential building are centralized, the number of available evacuation stairs and available fire elevators is limited, and high temperature and dense smoke generated by fire disaster bring difficulty to evacuation of crowded people in the evacuation process; thirdly, the proportion of old, weak, sick, disabled and children in the residential building is far higher than that of other types of buildings, but the people have poor mobility and weak self-rescue ability, and the people are more difficult to evacuate.
Meanwhile, once a fire disaster happens to the automobile garage, a great amount of casualties and property loss are easily caused, and due to the fact that the fire disaster happens in a building, people are relatively difficult to evacuate and fire rescue is relatively difficult. After a fire disaster occurs in the garage, the garage has the characteristics of complex type, rapid fire spread, difficulty in evacuation of people and vehicles, difficulty in fire extinguishment and rescue and the like.
Therefore, new designs are needed to meet the fire protection requirements and to accommodate the fourth generation medium and high rise residential buildings on board automobiles.
