Changchun Concrete Prefabricated Houses
The concrete prefabricated houses in Changchun are mainly prefabricated integrated houses, which are characterized by high efficiency, environmental protection, and wide applicability. Related enterprises offer a variety of products and supporting materials to ensure construction quality.
Prefabricated integrated houses fall within the scope of the building industrialization and prefabricated building industry. They involve the standardized production of building components in factories, followed by transportation to the site for rapid assembly into complete buildings. With steel structures or concrete frames as the main body, they integrate wall, roof, pipeline, and other systems to achieve standardized design, factory-based production, and assembly-based construction. In cold regions like Changchun, the use of high-performance insulation materials and thermal break structural designs enables buildings to maintain good thermal performance even at extreme temperatures of -30℃. Their modular design supports flexible combinations and is suitable for various scenarios such as residential housing, schools, medical facilities, and temporary structures. With high-precision components and minimal on-site wet work, they reduce construction waste and environmental pollution while significantly shortening construction periods, saving over 30% of construction time compared to traditional building methods.
Several enterprises in Changchun are engaged in businesses related to concrete prefabricated houses. Changchun Guoxin Prefabricated Building Development Co., Ltd. was established in July 2017 and primarily deals in the manufacture and sale of cement products, concrete structural components, and building blocks. It has an annual production capacity of 100,000 m³ of prefabricated components, meeting the construction requirements for 500,000 m² of prefabricated buildings, and produces 1 million m³ of commercial concrete annually. It has four production lines for prefabricated building components. Its product range is diverse, including prefabricated stairs, wall panels, hollow beams and slabs, columns, beams, composite floor slabs, prefabricated walls, and sandwich insulation walls. Additionally, other manufacturers offer prefabricated cement houses, mostly priced at 1,100 yuan per square meter, such as white cement movable houses, project department packing-box-style houses integrated with rural light steel villas, and container-style民宿 (homestays) made of color-steel plates for movable houses. These can be traded online, with delivery within 48 hours, compensation for shortages, and compensation for damages. There are also new types of assembled prefabricated houses priced at 300 yuan per square meter, locally wholesale finished cement houses, and locally shipped concrete prefabricated houses.
In terms of related materials, ECC high-ductility concrete is sold for reinforcing old houses and historical monuments without altering their original appearance. ZX-11 PC bedding mortar is suitable for bedding construction of prefabricated concrete beams, columns, and shear walls, sealing of prefabricated component joints, and bedding installation of equipment pads. ZX-15 rebar connection sleeve grout is suitable for connecting prefabricated components in industrialized and prefabricated residential buildings.
