Before you start reading this article, you may not know much about the introduction of concrete pouring sub-silo joints, but after reading, you must have a deeper understanding of this.
Concrete pouring sub-silo joint refers to the gap or division deliberately created when pouring concrete, so as to divide the entire pouring area into a number of relatively independent silos. The purpose of these sub-chamber joints is to control the shrinkage deformation, temperature change and stress concentration of concrete, so as to improve the stability and durability of concrete structures.
In the process of solidification and hardening, concrete will shrink and deform, that is, reduce volume. This shrinkage deformation may cause cracking or deformation of concrete, so it is necessary to limit the occurrence of shrinkage deformation by dividing the bin. The functions of the silo joint can be summarized as follows: controlling the shrinkage and deformation of concrete, alleviating the stress concentration caused by temperature changes, reducing the risk of concrete cracking, improving the durability of concrete structures, and improving construction efficiency.
In terms of practical application, concrete pouring sub-silo joints are often used in large-scale concrete structures, long-span bridges, underground building structures, dams and other projects. In these projects, due to factors such as large structural volume, large temperature changes or prestress application, the shrinkage deformation and stress concentration of concrete are more serious. By setting the sub-bin joint, the structure can be divided into relatively independent parts, reducing shrinkage deformation and stress concentration, and improving the stability and durability of the structure.
Concrete pouring sub-silo joint is an important concrete structure technology, which is used to control the shrinkage and deformation of concrete and alleviate the stress concentration caused by temperature changes. It is widely used in large concrete structures to improve the stability and durability of the structure and improve the construction efficiency.
