Description
Technical Field
The invention relates to the technical field of emergency disaster prevention and reduction, in particular to an emergency disaster prevention and reduction device for resisting storms in residential areas of wooden low buildings.
Background
The light wood structure house is a structural form which is formed by uniformly densely connecting specification materials with smaller member sections and is largely adopted by north American residential buildings, and the house is formed by jointly acting a main structural member (a structural framework) and a secondary structural member (a wall panel, a floor panel and a roof panel) and the like, bearing various loads and finally transmitting the loads to a foundation.
Storms are a disastrous weather phenomenon with high wind speeds, including tornadoes, tropical cyclones and wide-range temperate cyclones. Hurricanes and typhoons are tropical cyclones with wind speeds above 33 m/s, and have different names only due to different regions. The strong tropical cyclone generated in the northwest pacific ocean and south China sea is called "typhoon"; tropical cyclones generated in the eastern atlantic, caribbean, and north pacific are called "hurricanes".
Annual typhoons or hurricanes cause significant disasters including casualties, animal casualties, building damage and collapse, public facility damage and collapse, etc. to china, south-east asian countries, north-east asian countries, and coastal areas of north america.
When a storm disaster comes, people are the largest property, and therefore, firstly, the life safety of people is guaranteed not to be influenced by the storm disaster, and secondly, the normal life of people is guaranteed not to be influenced by the storm disaster. When a storm disaster occurs, the storm disaster is usually accompanied by strong rainfall to cause ponding and flood disasters, which cause water inflow and even water collapse of a low house with a wooden structure, at this time, how to provide a temporary living place located at a high place for a disaster-stricken, and how to find a safe place for storage, which is free from the storm and flood disasters, for emergency materials such as electricity, water, food, and medicines required by the normal life of the residents, because the living place is located at the high place, can the residents avoid the flood and the wind disasters? In addition, how to find a safe place to install for residents' property such as furniture and home appliances in a wooden low house which is easy to enter water in flood disaster? And the like, which are technical problems that need to be solved urgently by the technical personnel in the field.
Furthermore, since most residential houses in north america (mainly the united states and canada) are light-weight wooden low houses, the wind storm resistance is poor, the wooden houses are easy to collapse as soon as strong wind blows, and people need to rebuild the light-weight wooden low houses after the wind storm. Although light wood low houses have the advantages of low cost, quick construction and the like, hurricanes almost come every year, and the wood houses are blown down almost every year, are rebuilt almost every year, collapse, and damage to decoration, furniture, household appliances and other properties inside the houses can be caused, so that various disaster losses are combined together and are suffered once every year, and local residents are difficult to bear.
Therefore, how to provide an emergency disaster prevention and reduction device for resisting storms is a technical problem that needs to be solved urgently by technical personnel in the field, and the emergency disaster prevention and reduction device can be built quickly after receiving the early warning of the storm disaster and can also be disassembled quickly after the storm disaster passes.
