Concrete structure connecting method with lock catch mechanism adopted

Abstract

The invention relates to a concrete structure connecting method with a lock catch mechanism adopted, and belongs to the technical field of concrete structures. The connecting method comprises the steps that concrete cast first and concrete cast later are connected together; one or more than one concrete protrusion is arranged at the combining face of the concrete cast first and the concrete cast later and the protrusion is provided with a communicated hole; the concrete which is cast later is cast at the position of the combining face and the hole is filled with the concrete cast later; after maintenance and hardening, the concrete cast later and the concrete cast first are locked together at the position of the protrusion, and the concrete cast first and the concrete cast later are connected into a whole.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete structures, and in particular relates to a connection method of concrete structural members. Background technique [0002] In concrete structural engineering, there are many connection problems between concrete poured at different times, that is, pouring concrete on previously poured concrete structural components to form new structural components, such as the joints between prefabricated components in precast concrete structures, prefabricated The junction of concrete components and cast-in-place concrete, the construction joints and post-cast belts in the construction of concrete structures, and the pouring of concrete on existing components in the reinforcement and transformation of engineering structures, etc. [0003] In the existing technology, the connection between concrete poured in different periods generally relies on the bonding force between the old and new concrete and th...

Problems solved by technology

[0003] In the existing technology, the connection between concrete poured in different periods generally relies on the bonding force between the old and new concrete and the anchorage of steel bars. In some technologies, groove keys are used, but the bonding strength is low and it is easy to crack, which affects the performance of the structure and the impact on the structure. force performance
