Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a super-deep post-cast strip steel bar connection device. Background Art

[0002] During the construction of ultra-deep post-cast joints, due to the excessive depth of the post-cast joints, the steel bars on the upper part of the post-cast joints are relatively dense, making subsequent construction such as sealing and roughening on both sides of the post-cast joints difficult to achieve. At the same time, settlement differences occur between the post-cast joints. During construction, the steel bar joints avoid the post-cast joints, which limits the shrinkage strain of the reinforced concrete structure and affects the effective performance of the post-cast joints.

[0003] Since there are many steel bars inserted in the upper part of the post-casting strip, the use of traditional wooden formwork to support the formwork on one side will cause difficulties and waste during dismantling, and consume a lot of time. At the same time, the concrete side pressure on both sides of the ultra-deep post-casting strip is large, and the construction of the post-casting strip formwork using a steel mesh plus a double-layer quick-closing mesh is prone to formwork expansion and leakage, and there are unsafe factors.

[0004] In view of this, the utility model proposes a super-deep post-casting strip steel bar connection device. Utility Model Content
