The Firmness of Precast Concrete Houses

The firmness of precast concrete houses cannot be generalized. Traditional precast concrete panel houses have poor firmness, while regular prefabricated concrete houses offer reliable firmness.

Poor Firmness of Traditional Precast Concrete Panel Houses

Traditional precast concrete panel houses pose significant safety hazards, with prominent issues in terms of firmness. There are gaps at the edges of the panels, showing a marked difference compared to cast-in-place slabs that are poured as a whole. They perform poorly in sound insulation due to insufficient thickness and a structure that easily transmits sound, affecting the comfort of living. Leakage is a common problem in traditional precast concrete panel houses. Rainwater can easily seep through the gaps into the interior, corroding the steel bars and reducing the safety of the house structure. More seriously, even a minor earthquake can cause the house to collapse, posing a great threat to the lives and property of the occupants. Moreover, the quality of precast concrete panels on the market varies greatly, with most being inferior products and having an extremely short service life, further weakening their firmness and reliability.

Reliable Firmness of Regular Prefabricated Concrete Houses

Regular prefabricated concrete houses have obvious advantages in terms of firmness. Their walls are cast as a whole using C30 high-strength concrete, with national standard threaded steel as the framework. The factory uses precision steel molds to make the walls, roof panels, and floor panels into a complete load-bearing unit, ensuring the safety factor from a structural perspective. Standardized factory production keeps dimensional errors within the millimeter range, and concrete curing is carried out in a constant temperature and humidity environment, resulting in more stable quality. As long as they are produced by regular manufacturers, constructed in accordance with specifications, and have proper foundation conditions, such houses can be used for a long time. There is also an opinion that using C35 concrete grade along with national standard threaded steel, with the entire house cast as a single unit of reinforced concrete, makes it even sturdier than brick-concrete structures, enabling it to better withstand various external forces and ensure living safety.
