Flat Roof Cement Prefabricated Installation

There are two common methods for using cement prefabricated components on the roofs of rural flat houses, each with its own characteristics.

Direct Covering with Prefabricated Floor Slabs

When building flat houses in rural areas, using prefabricated floor slabs to directly cover the house structure is a relatively traditional method. This approach is relatively simple to operate. After the main structure of the house is erected, the prefabricated floor slabs are laid one by one on top of the walls to form the roof plane. However, this type of prefabricated floor slab roof has obvious drawbacks, being prone to water leakage and difficult to resolve. The water leakage problem can stem from multiple aspects. On the one hand, there may be gaps at the joints between the prefabricated floor slabs. If the sealing is not properly handled, rainwater will seep into the house along these gaps. On the other hand, as the house ages, the floor slabs may undergo slight deformations due to factors such as foundation settlement and temperature changes, further exacerbating the appearance of gaps and leading to more severe water leakage situations. Moreover, due to the structural characteristics of the prefabricated floor slabs, it is relatively difficult to carry out waterproof repairs, often requiring a significant amount of manpower and material resources.

Cement Houses with Prefabricated Reinforced Concrete Structures

There is also a type of cement house that adopts a prefabricated reinforced concrete structure, with the core process being factory prefabrication combined with on-site assembly. At specialized production bases, core components such as walls, floor slabs, and beams and columns are cast in one piece using high-precision molds. Each module integrates multiple structures and can be flexibly combined like "building blocks". The floor slabs of this type of cement house are also prefabricated components and offer many advantages. In terms of efficiency, a single 30㎡ module takes only 7 days to be prefabricated in the factory. After being transported to the site, with the cooperation of 3 workers and a crane, a single module can be installed in 4 hours, and the overall construction of a 100㎡ house takes only 2 days, greatly shortening the construction period and improving construction efficiency. In terms of cost, factory prefabrication enables large-scale production, reducing production costs. At the same time, on-site assembly reduces material waste and labor costs during the construction process. In addition, since the quality of the components can be better controlled during the factory prefabrication process, their structural performance is more stable and reliable, and the probability of quality issues such as water leakage is lower compared to traditional prefabricated floor slab roofs.
