Low temperatures, rain, snow and freezing weather continued.
Steel structure, lightweight roof structure, rain canopy, awning.
Temporary construction of board house, underground garage entrance.
Buildings and structures with large spans and large spaces.
Weak ability to work under pressure.
Plus the reason for the material properties of its construction itself.
Collapse is more likely to occur when covered with snow and ice.
What to do if a building collapses?
Here's how to save lives
Safety Tips
The majority of owners, housing property rights units and user units, project construction units, construction units, agricultural production units, etcQuickly carry out comprehensive investigation and monitoring of buildings and structures such as large-span frame structure buildings, bazaars, stadiums, agricultural greenhouses, etc., and remove snow in a timely manner, dredge drainage facilities, organize the transfer of endangered personnel in a timely manner to avoid danger, and strictly prevent collapse due to heavy snow.
Inspect the building in time and observe the quality of the building's appearanceButThere is a cracking condition of concrete components, a protective layer of reinforcementButloose, member connections and nodesButThere are corrosion, welds of steel roof components and column head insertsButThere are conditions that affect the structure such as loosening and corrosion. The found dangerous houses (hidden danger houses) or dangerous buildings should be entrusted with professional testing and appraisal institutions in a timely mannerTake effective detection, identification, and reinforcement measuresIn order to enhance the ability to resist disasters, evacuate people in time, so that they do not collapse in disasters, can be repaired as soon as possible after disasters, maintain the safety and stability of buildings, reduce the risk caused by snowfall, and avoid the occurrence of collapse accidents. During the freezing period of low temperature rain and snow, it should beTry to stay away from and do not enter dangerous buildings and long-span frame structure buildings, bazaars, stadiums, agricultural greenhouses and other buildings and structures. Detect the risk of collapse,Those who are in danger should evacuate immediately, and must not be greedy for property or recklessly rescue peopleand report to the local housing and construction departments and local people in a timely manner. Methods for preventing heavy snow collapse and snow removal in greenhouses
As long as the response is skillful, the greenhouse is strengthened and the snow is cleared in time to reduce the pressure on the greenhouse, and the phenomenon of shed collapse can also be avoided. Clever column methodAccording to the width of the greenhouse, a column with a diameter of not less than 8 cm is added every two meters under the beam frame to strengthen the bearing capacity of the scaffold.
Snow slides naturallyIf there is a condition, you can add a layer of greenhouse film on the grass, if not, roll up the straw, put it on the back slope of the greenhouse, and when the snow thickness is about 8 cm, it will automatically slide down on the smooth greenhouse film. The 7-meter-wide greenhouse can automatically slide down 2 3. The greater the slope of the shed, the more it will automatically slide down. This can effectively relieve the pressure of snow on the greenhouse.
Rapid snow plowingTake a bamboo pole about 5 meters long (the length of the bamboo pole can be lengthened according to the width of the greenhouse) and a wooden board with a length of 1 meter and a width of 20 cm to make a scraper, when the snow reaches 5 7 cm thick, stand on the back slope of the greenhouse, push the snow gently, the snow will slide down the smooth shed film, and damage to the shed film should be avoided during operation. *CCTV News, Hunan Emergency Management, China Emergency Management.
