Multi-adaptive quick splicing piece for connecting rods between steel bars of prefabricated concrete members

Abstract

The invention discloses a multi-adaptive quick splicing piece for connecting rods between steel bars of prefabricated concrete members. The multi-adaptive quick splicing piece comprises a first prefabricated concrete member, a second prefabricated concrete member, an inner side first splicing plate and an inner side second splicing plate; the top end of the first prefabricated concrete member is uniformly and integrally connected with first reinforcing steel bars; the second prefabricated concrete member is located above the first prefabricated concrete member, and the bottom end of the second prefabricated concrete member is uniformly and integrally connected with second reinforcing steel bars; the inner side first splicing plate is located on the inner side of an outer side first splicing plate; and the inner side second splicing plate is located on the inner side of an outer side second splicing plate. The multi-adaptive quick splicing piece for the connecting rods between the steel bars of the prefabricated concrete members adapts to the distance change between the first reinforcing steel bars and the second reinforcing steel bars, the connecting stability is improved through a structure reinforcing mechanism, and the connecting strength between the splicing structure and the first reinforcing steel bars and the connecting strength between the splicing structure and the second reinforcing steel bars are improved through concrete cylindrical rods and concrete connecting blocks.

Description

technical field [0001] The invention relates to the technical field related to construction, in particular to a multi-adaptive quick splicing piece for connecting rods between prefabricated concrete members and steel bars. Background technique [0002] The construction of buildings through prefabricated concrete components can reduce the working pressure of construction personnel, shorten the construction period, and quickly build buildings. Prefabricated concrete components are divided into several parts and prefabricated in the prefabricated site, and then assembled into a whole assembly structure at the construction site. The connecting parts of the prefabricated concrete components can also bear various loads generated during the installation process before the concrete is poured, and the steel bars on the prefabricated concrete components are spliced ​​by quick splices; [0003] The Chinese invention patent with the authorized announcement number CN11189443B discloses a...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a multi-adaptive fast splicing piece for connecting rods between prefabricated concrete components to solve the problem of the first reinforcing rod and the second fast splicing piece for connecting rods between prefabricated concrete components proposed in the background technology. The distance between the two reinforcement rods is variable, and the quick splicing piece of the connecting rod between the prefabricated concrete members is inconvenient to adapt to the first reinforcement rod and the second reinforcement rod with different distances, and the stability of the connection structure is poor. The wedge improves the connection strength between the splice structure and the steel bar, but the wedge and the wedge are inconvenient to insert outside the connection, and the connection strength is low
