Prefabricated Panel Houses in Rural Huaihua
Prefabricated panel houses were once common in rural Huaihua, but they have many drawbacks. Nowadays, prefabricated buildings are gradually becoming the mainstream choice.
In rural Huaihua, prefabricated panel houses were very popular in the self-built housing sector from the 1980s to the late 1990s. The prefabricated panels, also known as "five-hole panels," are long, pre-cast slabs made of cement and steel bars in factories. They are transported to construction sites and directly placed on top of built brick walls, laid side by side to form the floor.
However, prefabricated panel houses have significant drawbacks. Poor integrity: Since the panels are pieced together one by one, with cement mortar filling the gaps between them, the connections between the panels and the walls or ring beams are weak, resulting in poor overall integrity. Low earthquake resistance: Prefabricated panel houses should not be used in earthquake-prone areas due to their low seismic resistance. They are prone to collapse during earthquakes, posing a threat to life safety. Prominent waterproofing issues: There is a relatively high probability of water leakage when waterproofing is done. It is said that 8 out of 10 houses with prefabricated panel roofs experience water leakage, seriously affecting the living experience. Poor thermal insulation: The floor thickness is generally around 12 centimeters. Although it is hollow, its thermal insulation is poor. The indoor temperature is high in summer and low in winter. Usually, secondary roofing materials need to be added on the floor to compensate, increasing construction and usage costs.
As time goes by and people's demands for living quality increase, traditional brick-and-mortar self-built houses, including prefabricated panel houses, have gradually exposed problems such as long construction periods, uneven quality, moisture return and cracking, and poor thermal and sound insulation in the mountainous areas of Huaihua. Prefabricated buildings, with their efficient model of factory prefabrication and on-site assembly, are gradually becoming the mainstream choice for rural housing construction in Huaihua. For example, Hunan Happy Living Technology Co., Ltd. uses steel-concrete modular structures for its products, which have excellent earthquake resistance, wind resistance, moisture resistance, and sound insulation. They can be customized and renovated according to the size of the homestead, terrain elevation differences, and local climate conditions, effectively solving many pain points of traditional housing construction and providing rural residents in Huaihua with better living options.
