Liucheng Prefabricated Concrete Houses

There are manufacturers of prefabricated concrete components in Liucheng, but old prefabricated panel houses have poor earthquake resistance and pose significant safety risks compared to modern cast-in-place houses.

In the Liucheng area, there are manufacturers of prefabricated concrete components, such as the Liuzhou Liucheng laminated panel factory, which mainly produces laminated panels, prefabricated stairs, PC components, and other products. These prefabricated components are widely used in the construction field, improving construction efficiency and ensuring component quality.

However, during the Liuzhou earthquake on May 18, 2026, all 13 collapsed buildings were old prefabricated panel houses or brick-and-concrete houses. These old prefabricated panel houses have several problems: Firstly, poor earthquake resistance. The earthquake resistance of prefabricated panel buildings constructed in the 1980s is only 3 - 4 degrees, far below the endurance limit of this 5.2-degree earthquake. Secondly, poor structural integrity. The floor slabs are 'pieced together' on the walls, and the connections between the panel seams are weak. During an earthquake, it is very easy for the floor slabs to shift, walls to crack, and the entire building to collapse. Thirdly, old hidden dangers. These houses are generally over 30 years old and have problems such as wall weathering, steel bar corrosion, and foundation settlement, further weakening the stability and safety of the houses.

In stark contrast, cast-in-place commercial housing built after 2000 only had slight shaking during the earthquake and had no risk of collapse. Cast-in-place houses are constructed by directly binding steel bars and supporting formwork on the construction site, and then pouring concrete into the formwork in batches, making the entire floor slab, beams, and columns form a single piece with good integrity. During an earthquake, the house can bear and deform together, dispersing energy and making it less likely to have local collapses.

Therefore, although there are manufacturers of prefabricated concrete components in Liucheng, for house construction, full consideration should be given to safety factors such as earthquake resistance, and building methods with good structural integrity and strong earthquake resistance should be preferred.
