Precast concrete column structure and construction method thereof

Abstract

The invention relates to a precast concrete column structure. The precast concrete column structure comprises a first precast section, a core section, a second precast section and grouting holes, wherein the first precast section is formed in a precast mode, and a plurality of first steel bars are pre-buried in the first precast section; the core section is precast and arranged at the top of the first precast section, the first steel bars penetrate through the core section through holes and are partially exposed out of the top of the core section, and connecting pieces which partially protrudeoutwards and are fixedly connected with a cross beam are pre-buried in the core section; the second precast section is precast and arranged at the top of the core section, a plurality of second steelbars are pre-buried in the second precast section corresponding to the first steel bars, and the first steel bars extend into the second precast section through inserting holes and are in butt jointwith the second steel bars; and the grouting holes communicate with the joints of the first steel bars and the second steel bars and are formed in the second precast section. According to the precastconcrete column structure, the problem that a precast concrete column is difficult to construct is effectively solved, the connecting process is simplified, a temporary support does not need to be additionally erected, the construction efficiency is improved, and the overall stability of the concrete column is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated concrete column structure and a construction method thereof. Background technique [0002] With the development of social modernization, the application of prefabricated concrete structures is becoming more and more extensive, but the existing prefabricated concrete columns often need to bind steel bars on site at the connection nodes with the beams, and during the binding process, temporary supports need to be built to support them. The prefabricated section of the concrete column connecting the upper and lower nodes is more complicated to operate and the construction efficiency is lower, and the overall stability of the concrete column formed by pouring is also poor. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a prefabricated concrete column structure, which solves the prob...
