The function of the rolling straight thread connecting sleeve is to transfer the force in one steel bar to another steel bar, permanently ensuring the uninterrupted transmission of tensile force, so that it can ensure that the steel bar reaches the same strength in the building force system, so the steel bar is connected The quality of the sleeve is critical, and the mechanical properties of the sleeve (strength, ductility, stiffness, fatigue performance, durability, construction adaptability and quality stability) must be ensured to ensure the quality of the steel connection. Then the advantages of steel sleeves compared with traditional industry processes are as follows:
Improve labor rate and reduce construction costs. The use of modern processing equipment for steel bar processing greatly reduces labor costs and improves worker productivity; reduces material waste and energy consumption. The processing of commercial steel bars is carried out in strict accordance with the design drawings and standards to ensure the fixed length and precision of the steel products, which cannot be achieved by traditional equipment.
The management procedures on the construction site are simplified and the number of operators is reduced, which reduces the management and labor costs for construction enterprises and units, thereby effectively controlling the overall cost of steel bar processing, and solving the shortage of workers on site steel bar processing and the difference in skills of workers. Difficulties such as equipping and occupying land;
Speed up the construction progress and improve the construction quality of steel bar projects. The specialized production of steel bar processing can ensure the processing accuracy of the steel bar products (rebar length, bending angle, steel bar shape, etc.), which cannot be achieved by on-site manual operation. At the same time, the application of numerical control management system and the use of electronic instruments can simplify the working procedures of each production link. Shorten the steel bar processing cycle and construction period to ensure the delivery time and construction schedule.
It is conducive to the promotion and application of high-tech. Promote the specialized processing, production and supply of steel bars at the industrialization level of building construction, and realize the on-site assembly operations of steel bar projects, which not only guarantees the quality of the project, but also guarantees the construction progress, and promotes the development of building industrialization. The centralized processing and distribution of steel bars is conducive to safe production and civilized construction at the construction site, and makes the construction of steel bars safe, environmentally friendly and energy-saving. The centralized processing and distribution of steel bars is also conducive to the promotion and application of high-tech advanced equipment and advanced technology, improving the level of processing technology and construction level, promoting technological progress in the construction industry, and promoting the development of building industrialization.
Economic and social benefits. Because commodity steel bars reduce processing losses and reduce the overall project cost, it can also deliver formed steel bars to multiple construction sites at the same time, which can be integrated cut, improve the utilization rate of steel bars, save resources, and reduce Construction enterprise steel bar production cost;
