After the collapse of Linfen Hotel in Shanxi, Shanxi carried out a special safety inspection of buildings and people gathering places throughout the province. ? We will investigate all the houses in the town, including business premises and private houses, mainly depending on the year of construction, structure, materials and appearance. There are nearly 654.38+00000 houses. ? The person in charge of a town government in Linfen said.
Juxian Hotel in Chenzhuang Village, Linfen City, Shanxi Province collapsed while holding an 80th birthday party for an old man in the neighboring Anli Village. The banquet hall of Juxian Hotel where the incident happened was a courtyard covered with prefabricated panels. The Beijing News reporter learned from a number of construction professionals that villagers' self-built manhole covers may lack standardized design, and improper behavior during construction and use may also damage the overall structure of the house, thus increasing the risk of house collapse.
The local collapse of Juxian Hotel in Chenzhuang Village, Taosi Township, Xiangfen County, Linfen, Shanxi Province continues to attract attention. After the incident, the hotel owner Qi Moumou has been taken away by the police for investigation. The village director of the village where Xicollapse Hotel is located introduced that the hotel involved began in the 1980s. Construction workers were temporarily invited to the village, and the construction was completed in six times.
Juxian Hotel is close to the road and is a house built by villagers. The first floor of the house was built in the 1980s. In recent years, due to the continuous heightening of roads, the original floor became underground, so a second floor was built. Later, the attic, bedroom and kitchen were built, which was expanded five or six times in the past ten years.
Among them, the collapsed banquet hall was originally a courtyard between the main house and the back bedroom for banquets. More than ten years ago, the hotel owner built a layer of prefabricated panels on the yard. Rescuers said that the accident was the collapse of prefabricated panels above the yard. The main house, kitchen, bedroom and other buildings around the banquet hall are basically intact.
It is understood that precast slabs are concrete precast members prefabricated in the factory. When making precast slabs, the hollow model is nailed with wooden boards and paved with steel bars, and then the hollow part of the model is filled with cement. Knock off the board when it is dry, and the rest is prefabricated board, which can be transported directly to the construction site for installation.
Chen Gong, a structural engineer of an architectural design institute in Beijing, told the Beijing News reporter that compared with the popular on-site pouring of concrete, precast slabs were widely used in China before the end of last century because of their low cost and convenient use. ? At that time, reinforced concrete was expensive, and houses were mostly brick-concrete structures. Workers build walls on site and then cover them with prefabricated panels. ?
Around 2000, with the decline of reinforced concrete price and the maturity of concrete technology, the functional requirements of buildings became more complicated, and precast slabs and brick-concrete structures were gradually replaced. There is no prefabricated panel manufacturer in this village. In the past, prefabricated panels were mostly purchased from Nanliang Village, Dengzhuang Town, with a distance of about 10 km, but they have been rarely used in recent years.
A person in charge of the government of Dengzhuang Town said that there were indeed many precast slab factories in Dengzhuang Town earlier, and the products produced were sold to the surrounding areas. But it has been rare in recent ten years. Last year, all the factories were banned for environmental reasons. ? Nanliang Village, a villager who produced prefabricated panels seven or eight years ago, piled several piles of prefabricated panels. There is no market for a long time. ? Another prefabricated board factory in the village is in a sorghum field, and some prefabricated boards are piled at the door. According to the villagers, the boss has switched to driving excavators.
Most of the houses in Nanliang Village are reinforced concrete, and prefabricated panels can only be seen in vegetable gardens and sheds. In Chenzhuang Village, where Juxian Hotel is located, most of them are reinforced concrete structures. Villagers told reporters that most of these houses were built after 2000. There are basically no prefabricated panels. ?
