Description

Technical Field

[0001] The present application relates to the technical field of embedded parts for construction columns, in particular to an embedded part for a construction column that can partially replace the beam reinforcement protection block. Background Technique

[0002] The construction column is an essential seismic measure for the reinforced concrete structure infill wall. The main reinforcement of the construction column is set in two ways: embedded and post-installed. Before pouring the concrete of the beam and slab, the lower main reinforcement of the construction column can be embedded in the beam and slab, and the upper main reinforcement mainly adopts the post-installed method.

[0003] Common post-installed methods: 1. Embedded steel plate method: Embed a steel plate on the beam, and weld the main reinforcement of the construction column to the steel plate after removing the formwork; 2. Rebar planting method: Plant rebars at the bottom of the beam, and then tie the main reinforcement of the construction column firmly to the planted rebars.

[0004] The main disadvantage of the embedded steel plate method is that there is a large amount of on-site high-altitude welding, and the welding operation environment is poor. The drilled holes in the rebar planting method often conflict with the dense rebars at the bottom of the beam, resulting in many waste holes, inaccurate drilling positions, and large deviations in the planted rebars, which makes it impossible to effectively connect the planted rebars with the main reinforcement of the construction column, and the quality problems of the upper main reinforcement after construction are very common.
