Abstract

The invention provides an assembly type reinforced concrete frame beam column joint. The assembly type reinforced concrete frame beam column joint is characterized by comprising a prefabricated column and a prefabricated beam, wherein the prefabricated column is provided with a prefabricated column body, an extension section and at least one pair of column lap joint longitudinal ribs; the extension section is arranged in the center of the prefabricated column body and extends to the two sides; each pair of column lap joint longitudinal ribs are arranged in the extension section, penetrate through the whole extension section and extend out from the two ends of the extension section; the prefabricated beam is provided with a prefabricated beam body and at least one pair of prefabricated beam longitudinal ribs arranged on the prefabricated beam body; one ends of each pair of prefabricated beam longitudinal ribs extend out from the end, close to the prefabricated column, of the prefabricated beam body; the prefabricated column and the prefabricated beam are connected through a plurality of stirrups and ultra-high performance concrete; and the column lap joint longitudinal ribs and the prefabricated beam longitudinal ribs are fixed through the multiple stirrups according to a certain interval.

Description

technical field [0001] The invention relates to an assembled reinforced concrete frame beam-column joint and a preparation method for the assembled reinforced concrete frame beam-column joint. Background technique [0002] In the existing technology, the performance of integrally assembled joints connected with prefabricated components by post-cast concrete is closest to that of cast-in-place joints, and the commonly used connection methods for reserved steel bars between prefabricated beams and columns are sleeve grouting and steel grout anchor technology. Sleeve grouting has high requirements on the professional technical ability of workers during construction. The large number of sleeves in the project and the closed appearance are not conducive to quality inspection. The steel grout anchor is too long due to the overlapping length of the steel bar, and there are many wet operations on site, so the advantages of the prefabricated building are not obvious. Seriously restr...
