Tongnan Prefabricated House

The following is an introduction to Tongnan prefabricated houses:

Production Entity and Concept

In the north area of Tongnan High-tech Zone, Sany Construction Technology (Chongqing) Co., Ltd. adheres to the concept of 'industrializing construction and making building construction easy for everyone'. It focuses on prefabricated housing-related businesses and provides customers with one-stop SPCS fully assembled building overall solutions, covering the entire process services including deep design, production, transportation, and installation of PC components.

Product Types and Production Capacity

Its products are diverse, including prefabricated walls, prefabricated columns, composite slabs, composite beams, prefabricated stairs, etc. The annual production capacity of prefabricated components exceeds 150,000 cubic meters, which can meet large-scale construction demands.

Environmental Protection Advantages

Prefabricated buildings adopt a large-scale intensive production method and demonstrate significant environmental protection benefits in multiple aspects. On the one hand, they can save consumables, reduce energy consumption, and minimize the generation of construction waste. On the other hand, during the construction process, the use of mechanized installation methods can effectively reduce pollution such as noise, exhaust gas, waste, and wastewater emissions, and lower carbon emissions throughout the entire building life cycle. In addition, prefabricated buildings reduce the input of cast-in-place formwork. In the traditional construction industry, cast-in-place formwork is usually discarded after being used at most four times, while the prefabricated molds used in prefabricated buildings can be reused nearly a thousand times and can also be remelted and remanufactured, greatly saving resources and reducing construction waste.

Technological Innovation

Sany Construction Technology has independently developed a patented product, the hollow column, which weighs half as much as traditional columns, facilitating transportation and on-site assembly and effectively reducing labor and time costs. At the same time, the company has independently developed production process methods for composite concrete structural walls, columns, beams, and slabs, and has developed equipment such as composite shear wall production, composite column integral molding, welded steel reinforcement cage molding, and steel bar sleeve extrusion, achieving fully automated production of prefabricated components. In addition, it has developed construction methods such as rapid installation construction technology for composite concrete structures and installation construction technology for welded steel reinforcement cages in composite concrete structures, realizing composite construction of concrete structures. This technological system has currently had 93 patents accepted, including 24 invention patents, 69 utility model patents, 2 authorized patents, and has published one monograph.
