Shanghai Tongding Building Materials Co., Ltd.

Shanghai Concrete Ding Building Material Co., Ltd., adhering to the concept of "people have nothing, people have their own advantages", has continuously increased investment in scientific and technological research and development, while rationally adjusting product structure, constantly strengthening market development efforts, and establishing cooperative relations with many enterprises. The company mainly produces and sells spacers for construction projects, mechanical equipment for spacers for construction projects, plastic moulds for spacers for construction projects, technology transfer for spacers for construction projects (C70-C100), etc.Overview of Spacing Parts in Construction EngineeringSpacers in construction projects are related to the bearing capacity, durability, waterproofing and fire resistance of structures. The company produces construction engineering spacer, construction engineering spacer mechanical equipment, construction engineering spacer plastic mold. The technology of spacers in construction works fully conforms to the national standards of the People's Republic of China GB50204-2002 "Code for Acceptance and Acceptance of Construction Quality of Concrete Structures", TB10005-2002 "Code for Design of Concrete Structures", TB10005-2010 "Code for Design of Durability of Railway Concrete Structures", JGJ/T219-2010 "Technical Specification for Application of Reinforced Spacer in Concrete Structures", TB/T3432-201. 6. Prefabrication of post-tensioned pre-stressed concrete simple-supported beams for high-speed railway.The company's construction engineering spacer, construction engineering spacer mechanical equipment, construction engineering spacer plastic mold has the following characteristics;1. Cement-based spacers are made by pouring and pressing: (1) High strength: cement-based spacers for high-strength construction projects are made of sand, stone, cement, silica powder, mineral powder, fibers, etc., and are cured by immersion and natural maintenance. The strength reaches (C70-C100). (2) The size of cement-based spacers is accurate and the height of the protective layer is engraved. (3) The expansion coefficients of cement-based spacers are the same, and the materials used have the same adhesion and expansion coefficients as concrete. Effective prevention of air, rain, sea water and other infiltration caused by steel corrosion, greatly improving the durability and safety of reinforced concrete. (4) After demoulding, the cement-based spacers have no color difference, the interface between the cement-based spacers and the template is small and stable, and there is no "patch" after demoulding. It is especially suitable for fair-faced concrete structures. (5) Cement-based spacers have high durability, high quality materials, no pore and no water seepage, low alkali content and high durability. (6) Cement-based spacers are easy to construct and can fix reinforcing bars with perforated wire. A fork with an iron clamp will do. With a wire, it's OK. 2: Metal-based spacers: the world's advanced seven-axis robot is used to form precisely at one time. The exposed parts are equipped with anti-corrosion and anti-rust coatings.3: Plastic-based spacers: Engineering plastics can be used to produce spacers of different colors.
