Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building steel bars, in particular to a steel bar connection structure used in concrete phased construction. Background Art
[0002] Staged concrete reinforcement connection refers to the connection of the reinforcement between successively cast concrete components during concrete structure construction. This connection method is of great significance for ensuring the overall performance and safety of the structure.
[0003] Traditional methods of connecting steel bars in the second-stage concrete are mainly welding and binding, but these methods have certain limitations in practical applications, such as difficult quality control and low construction efficiency. Especially in water conservancy projects such as aqueducts, there are a large number of small structures such as end parts during concrete pouring construction, which must be constructed by second-stage concrete pouring, and there must be steel bars connected between the first-stage concrete and the second-stage concrete according to design requirements. However, if welding and binding are used to connect the traditional second-stage concrete steel bar connection methods, the connected steel bars must be exposed to a certain length of the first-stage concrete formwork during construction to connect with the later steel bars. This results in the first-stage concrete formwork being able to be only wooden or bamboo clamp formwork, which is destructively dismantled when the formwork is removed, so it can only be used once, which wastes the formwork and is not easy to construct. For this reason, we designed a steel bar connection structure used in concrete phased construction. After using this structure, the formwork does not need to be destroyed and it is convenient for subsequent steel bar connection and normal construction. Utility Model Content
