Prefabricated Three-Story House

Under reasonable design and standardized use, a prefabricated three-story house is feasible, but attention must be paid to load-bearing safety and other issues.

Accident Case Warning

On April 11, 2024, a three-story prefabricated slab house in Fengshouchang, Guanba Town, Zhong County, Chongqing City, experienced a slab fracture accident, resulting in 2 deaths and 3 injuries. The cause of the accident was that the temporary load accumulated on the second-floor slab was too large, exceeding the load-bearing capacity of the prefabricated slab, leading to brittle fracture and collapse of the slab. This indicates that during the use of a prefabricated three-story house, strict control over the load must be maintained to avoid overloading. If the load-bearing capacity of the house is underestimated and heavy items are randomly stacked on the floor, even a three-story structure can trigger serious safety accidents, threatening the lives of the occupants.

Applicable Construction Technology

The block construction technology in prefabricated buildings is suitable for low-rise houses of 3 to 5 stories. For a three-story prefabricated house, this is a feasible construction method. Using this technology, various parts of a small building can be directly manufactured in a factory according to the finalized architectural drawings. Subsequently, these prefabricated components are transported to the construction site, where only fixation operations are required to complete the main structure of the house, followed by furniture arrangement. This construction method has advantages such as fast construction speed and relatively stable quality, which can ensure the structural safety and overall quality of the three-story prefabricated house to a certain extent.

Market Supply Situation

There is wholesale sales information for three-story cement houses on the market. For example, Shandong Jining Jianwei Prefabricated Movable Cement Houses offers a product with specifications of 3.757.53 at a price of 380.00 yuan per square meter. The number of stories can be customized, and it features convenient disassembly and mobility. This indicates that there is a certain supply and demand for three-story prefabricated houses in the market. Consumers can choose suitable prefabricated house products according to their actual needs. However, when choosing, attention should be paid to factors such as product quality and the reputation of the manufacturer to ensure that the purchased three-story prefabricated house meets safety standards.
