Prefabricated concrete structure splicing structure

Abstract

The invention discloses a prefabricated concrete structure splicing structure. An upper force bearing rebar is embedded into an upper prefabricated component, a lower force bearing rebar and a steel sleeve are welded together and embedded into a lower prefabricated component, the steel sleeve is filled with epoxy resin mortar, when the upper prefabricated component and the lower prefabricated component are spliced, the epoxy resin mortar is pre-cast through an edge joint, the upper force bearing rebar and the lower force bearing rebar are connected together, during connection, the overflowingepoxy resin flows into the edge joint to form an epoxy resin mortar structure splicing layer, the overall splicing strength can be improved, and the anti-corrosion effect of the rebars is achieved. The operation is easy, the construction efficiency is greatly improved, the construction process is reduced, the construction period is shortened, the filling quality of the epoxy resin mortar is easilyguaranteed, on the premise of guaranteeing the connecting safety of the structure, the construction cost and difficulty are greatly reduced, the requirements of green building construction are met, and the prefabricated concrete structure splicing structure is worthy of being popularized.

Description

technical field [0001] The invention relates to the field of construction, in particular to a splicing structure of a prefabricated assembled concrete structure, which can be widely used in assembled concrete structures. Background technique [0002] Reinforcement connection technology is the key technology of prefabricated concrete structure. At present, the prefabricated component reinforcement of prefabricated concrete structure mainly includes sleeve grouting connection, grout anchor connection and mechanical connection and other technical means. The traditional sleeve grouting connection often has special requirements on the structure of the prefabricated sleeve components, and the processing technology is complicated, which greatly increases the construction difficulty and project cost; the traditional grout-anchor connection has relatively high construction requirements, and frequent grout leakage and secondary grouting , Poor slurry fluidity, grouting is not dense, e...

Problems solved by technology

The traditional sleeve grouting connection often has special requirements on the structure of the prefabricated sleeve components, and the processing technology is complicated, which greatly increases the construction difficulty and project cost; the traditional grout-anchor connection has relatively high construction requirements, and frequent grout leakage and secondary grouting , poor slurry fluidity, grouting is not dense, etc.; mechanical connection has high requirements on the connection joints, and it needs to be divided into various grades according to the joint ductility to adapt to various reinforcement strengths and meet the connection strength requirements. Excessive cost is required

The above-mentioned connection methods are costly, difficult to construct, and have a long construction period
