Prefabricated Floor Slabs for Houses in Chengdu
Prefabricated floor slabs for houses in Chengdu have many characteristics in terms of brands, products, applications, and renovations.
Brands and Manufacturers: There are numerous prefabricated slab brands and manufacturers in Chengdu, such as Xinfa Building Materials, Yongshi, Guobang, Huajin Reinforcement, Chenggou, Shuoxin, Xianglong Xingsheng, Shenbo, Bella Mo, and Ando. These brands and manufacturers offer a diverse range of choices to meet the needs of different construction projects.
Product Types and Specifications: The prefabricated floor slabs for houses in Chengdu come in various shapes, including panel-shaped and rectangular ones. Their compressive strengths also vary, with common values being 30 MPa, 95 MPa, and 200 MPa, enabling them to adapt to the load-bearing requirements of different building structures. Prices differ based on type and specification. For example, a cement block concrete steel reinforcement cover with a C50 rating, featuring a plum-blossom flat bottom, suitable for beam yards, building floors, and roof slabs, costs 0.20 yuan per piece. A floor load-bearing slab that is moisture-proof, lightweight, and high-density concrete prefabricated slab costs 20.00 yuan per piece. A prefabricated composite slab, an assembled truss composite floor slab, a prestressed concrete cast-in-place baffle, a solid block that is corrosion-resistant, costs 210.00 yuan per square meter.
Applications: In the 69-acre residential land project in Yongquan, Chengdu, Sichuan, a large number of prefabricated composite floor slabs and ALC panels (autoclaved aerated concrete panels) were used in construction, with a prefabrication assembly rate of 40%. This construction method combines prefabricated slabs with cast-in-place concrete to form an integral structure, which is conducive to improving the seismic performance of buildings and reduces carbon emissions per unit of building area by 20% compared to traditional cast-in-place processes. However, from the 1950s to the 1980s, there were a large number of prefabricated slab buildings in Chengdu. During the 2008 Wenchuan earthquake, some prefabricated slab buildings constructed in 1999 developed cracks, exposing safety hazards. Nowadays, in rural areas, prefabricated slabs have been largely replaced by safer cast-in-place slabs, and a large number of prefabricated slab houses across the country still face renovation challenges.
Renovation Explorations: Zhejiang pioneered the "Special Fund for Renovating Prefabricated Slab Houses" in 2024, raising funds through methods such as issuing special bonds, and has successfully launched multiple original demolition and reconstruction projects. Beijing, Shanghai, and other places have revitalized old houses by reinforcing and renovating prefabricated slab houses, installing elevators, and improving supporting facilities.
