The design concept of grouting sleeve holder mainly includes the following aspects:
Easy installation and convenient construction: The design of grouting sleeve holder focuses on the ease of installation and the convenience of construction. Through optimized design, the installation process of the holder is faster and easier, thereby improving the construction efficiency.
Reliable connection: The design of the holder ensures the reliability of the steel bar connection. Through reasonable structural design, the grouting material and the steel bar are tightly meshed, so as to achieve effective force transmission between the steel bar and the sleeve, and achieve the first-level joint performance.
Low cost: In the design process, considering the cost factor, low-cost materials and simplified production process are used, so that the cost of grouting sleeve holder is relatively low, which is suitable for large-scale construction projects.
Wide application range: The design of the holder takes into account a wide range of applicability and can be applied to different types of building structures and scenes, such as vertical components and beam steel bar connections of prefabricated buildings.
Material selection and process optimization: According to different usage requirements, choose appropriate materials and processes. For example, ductile iron grouting sleeves utilize the high strength and good toughness of ductile iron, while steel grouting sleeves use high-quality carbon structural steel or alloy structural steel, which is formed by cold extrusion or roll forming to improve processing efficiency and the feasibility of mass production.
Optimization of mechanical properties: During the design process, focus on the optimization of mechanical properties. By reasonably designing the rib structure and sleeve wall thickness, it is ensured that the grouting material is not easy to break during the force process, and the force transmission link will not fail, thereby ensuring that the steel bar will not be pulled out.
