Quzhou Concrete Prefabricated Houses

At present, complete and detailed information on concrete prefabricated houses in Quzhou has not been found, but relevant situations can be inferred from the development of prefabricated buildings in Quzhou.

Policy Orientation for the Development of Prefabricated Buildings in Quzhou

Guided by the development concepts of innovation, coordination, greenness, openness, and sharing, Quzhou County has vigorously developed prefabricated buildings, covering prefabricated concrete structures, steel structures, and timber structures. In terms of work objectives, starting from January 1, 2020, the proportion of prefabricated buildings in newly-built building areas in the county seat should reach more than 20%. It also encourages rural residents to use prefabricated buildings for their self-built houses and strives to make the proportion of prefabricated buildings in newly-built building areas in the whole county reach more than 30% in about 10 years. This shows that Quzhou County has clear plans and a proactive attitude towards the development of prefabricated buildings. As a form of prefabricated buildings, concrete prefabricated houses will also receive policy support and guidance.

Potential Impacts of Key Tasks on Concrete Prefabricated Houses

• Improving Design Capabilities: Promote universal, modular, and standardized design methods to enhance the integrated design capabilities of prefabricated buildings and the collaborative design capabilities of various disciplines. This helps concrete prefabricated houses achieve standardization and normalization at the design stage, improve design efficiency and quality, and make the structure and layout of the houses more reasonable to meet the needs of different users.
• Enhancing Construction Level: Encourage enterprises to develop efficient connection technologies, research and develop equipment and tools suitable for the construction characteristics of prefabricated buildings, and innovate construction organization methods. For concrete prefabricated houses, efficient connection technologies can ensure the firm connection between prefabricated components. Appropriate construction equipment and tools can improve construction accuracy and efficiency, and innovative construction organization methods can optimize the construction process and shorten the construction period.
• Strengthening Quality and Safety Supervision: Improve relevant management systems and strengthen supervision throughout the entire process. This can ensure that every link of concrete prefabricated houses, from the production of prefabricated components to on-site installation, complies with quality and safety standards, guarantee the stability and safety of the houses, and make users feel at ease when living in them.

Basic Support Provided by Concrete Procurement Projects

There are concrete procurement-related projects in Quzhou County. For example, the Quzhou resettlement housing project of China Communications Construction Ruitong conducted a concrete procurement tender, involving various strength grades of concrete, including C15, C20, C25, C30, C35, and C40. This provides a rich choice of materials for the construction of concrete prefabricated houses. According to the design requirements and usage functions of the houses, concrete with an appropriate strength grade can be selected to make prefabricated components.
