Literally, a dangerous wall is a precarious wall, the wall may collapse at any time, which is harmful and dangerous. A farm restaurant in a rural area of Xiangfen County, Linfen, Shanxi Province, was the victim of a serious accident caused by the collapse of a dangerous wall. The collapse of the hotel called polycentric hotel, the collapse accident occurred on the day of the hotel is being held a birthday party, this is everyone happy happy event, but did not expect an accident took the banquet more than twenty people's lives, happy event into a funeral. After the incident, Xiangfen County, the local immediately sent a task force to investigate the accident, the professional investigation found that the reason for the collapse of the polycentric hotel is that the hotel belongs to the rural self-built house, the house was built long time ago, coupled with the owner of the hotel is also the hotel to carry out the second transformation, the years of dilapidation and the second transformation of the house seriously affected the security. Polycentric Hotel can be considered an old hotel, the hotel's load-bearing capacity and stability decline in the dozens of people in the birthday party, the hotel finally could not withstand, collapsed.

The building material for the Juxian Hotel was prefabricated panels, and the hotel collapsed when the prefabricated panels fell. Prefabricated panels are commonly used in the construction industry a building materials, it is a prefabricated hollow plate, prefabricated panels inside only a few thin steel, some people will say, is not because the steel is too thin leading to prefabricated panels load-bearing capacity is not strong and caused by the collapse, the local Housing and Urban Renewal Authority professionals said that although the prefabricated panels within the steel is very thin, but these steel is processed through a special technology, there is generally no problem of load-bearing. Although the prefabricated panels themselves have no safety problems, but I would like to say that the Juxian Hotel prefabricated panels inside the steel rust, steel reinforcing bars are less than the thickness of the thumb, such building materials conditions are difficult to ensure safety.

The hotel's side wall was already in a precarious state before the collapse. A local resident revealed that he had seen one side of the hotel's wall seemingly collapsing, only to be supported by the wall and not collapsing, which makes the Juxian Hotel no longer safe.

I believe that everyone is just as reluctant to see such sad news, in order to their own as well as the safety of others, the rural self-built houses do not arbitrarily remodeling.
