In recent years, the color steel tile houses that were once all the rage in the countryside have almost disappeared and have basically been demolished. As for the reason, the focus is on safety, one is that there is foam in the walls of the color steel tile house, which is extremely flammable and has fire hazards; The other is that it is not strong enough, and in case of heavy storms and rainy weather, the roof is easy to be overturned, resulting in safety accidents. Therefore, now the color steel tile houses must be demolished.
Recently, the author saw such a news, saying that after the color steel tile house, another type of house will be demolished, this kind of house is a prefabricated board house. Whether it is urban or rural, all houses built with prefabricated panels must be investigated, and then demolished. Is this true? Why do you want to dismantle the prefabricated house?
Prefabricated panels are a very common building material in the past, and are widely used in various types of buildings in urban and rural areas. The so-called prefabricated slab refers to a kind of prefabricated concrete parts produced and processed in the precast yard, which can be directly transported to the construction site for installation.
The author is a post-80s generation in the countryside, and when I was a child, I could often see piles of prefabricated panels on the roadside in the village, because at that time it was popular to build bungalows in the village, and prefabricated slabs were the necessary materials for the roofs of bungalows. Individual families who can afford to build a two-storey building will also choose to use prefabricated panels. Even the primary school in the village will use a large number of prefabricated panels to build a teaching building.
The prefabricated slab is made of cement and steel bar, and the middle is empty, with multiple circular cavities, and a little steel bar head will leak out at both ends. When the house is built to the top, a crane will be found to lift the prefabricated slabs one by one, place them on the roof, and then use cement to make the prefabricated slabs fit and strengthen the wall, and finally brush another layer of cement on them, and the roof will be built.
Before the popularization of integrated roof pouring, prefabricated panels were generally used in rural areas, including many cities to build bungalows and multi-storey buildings. The use of prefabricated panels to build a house has such advantages: first, the construction time is short, and the roof installation is often completed in half a day; Second, the consumption of building materials such as steel bars is low, and the overall cost is low.
Because of these advantages of prefabricated panels, it is all the rage. But later, with the development of the times, there are fewer and fewer prefabricated houses in rural areas, until recent years, there is news that all prefabricated houses will be demolished, is this true? And what is the reason for the prefabricated slab to fall into such a situation?
As early as 2023, the relevant state departments issued a document clearly requiring "prohibiting new construction, reconstruction, and expansion of prefabricated houses and other buildings that do not meet the current norms within the scope of urban construction land". Subsequently, all parts of the city began to remove prefabricated slab buildings.
However, there is no news of the demolition of the existing prefabricated houses in the countryside, but if they have become dilapidated now, they will definitely be demolished. If the rural prefabricated panel house is in good condition, you don't have to worry about demolition. In other words, there is no problem of "dismantling prefabricated houses in rural areas".
As for why the prefabricated panel house has "fallen" to this point, there are many reasons: first of all, in terms of safety, the prefabricated panel roof is not strong enough, and the entire roof is made of multiple prefabricated panels, which is insufficient in strength and has great safety hazards.
Secondly, there will be gaps in the splicing of prefabricated slabs, and improper construction is easy to cause cracking of floor slabs. Especially when the house has a foundation settlement, the cracking of the prefabricated slab roof will be more serious.
Again, the prefabricated slab roof is easy to leak, because the entire roof is spliced, and some prefabricated slabs will be filled with bricks and cement, and the roof is not a whole piece, and it is easy to leak due to long-term wind and sun. This is also the reason why there were often professional "roof leak repair" vendors who walked the streets and alleys in the past, because almost every household has this demand for prefabricated prefabricated houses.
It is precisely because of these shortcomings of prefabricated houses, especially the existence of potential safety hazards, that new prefabricated houses are now prohibited in the city, and existing prefabricated houses have begun to be cleaned up and demolished.
