steel sleepers were first popularized and applied in the market by QEST Fangqiao Foundation in the early 11th Five-Year Plan period in China, under the background that the country proposed to build a resource-saving society and vigorously develop circular economy. The case proves that steel sleepers have the advantages of high economic efficiency, energy saving and environmental protection, high molding quality, etc., which can greatly reduce the number and intensity of construction workers, shorten the construction period, reduce transportation costs, and have low comprehensive engineering cost. They are ideal building materials for energy saving, and can be widely used in general industrial and civil buildings.
the steel sleeper is a temporary supporting structure to ensure the concrete structure to meet the requirements of casting forming, and it has to bear the horizontal load (lateral pressure of concrete) and vertical load (self-weight of building formwork, material structure and construction load) during the construction of the concrete structure. The premise of using steel sleepers is to ensure the quality of concrete engineering and construction safety, and to ensure that steel sleepers have sufficient rigidity, bearing capacity and stability. In the production of steel sleepers, qualified raw materials and accessories must be strictly selected to ensure their own reliability and meet the existing quality standards of reinforced concrete. It is forbidden to use blockboards and waste wood for splicing in the production process.
