Abstract

The invention discloses a prefabricated concrete column component which comprises concrete and a steel framework. The steel framework is poured in the concrete and comprises longitudinal tensioned steel bars, stirrups and longitudinal constructional steel bars. The longitudinal tensioned steel bars and the longitudinal constructional steel bars are attached to the inner sides of the stirrups and bound and fixed to the stirrups. Steel bar coupling devices are arranged in the prefabricated concrete column component. By adoption of the prefabricated concrete column component, the number of the longitudinal constructional steel bars is effectively decreased, the space between the steel bars is increased, the number of steel bar connectors is decreased, construction at beam-column joint zones is simplified, the construction speed is increased, the concrete pouring quality is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of construction, in particular to a prefabricated concrete column component. The invention also relates to a connection node for precast concrete column elements. Background technique [0002] Such as figure 1 and figure 2 As shown, in the current poured reinforced concrete frame structure, the longitudinal reinforcement of the frame column is generally evenly distributed along the periphery of the section. The current code "Code for Design of Concrete Structures" GB50010-2010 has corresponding regulations on the spacing of longitudinal reinforcement and hoops. Regulation. With the vigorous development of construction industrialization, more and more applications of prefabricated concrete frame structures are used; the prefabricated beams and columns in the structure are produced in factories and assembled on site, and are generally connected by post-cast node areas to form an integral frame. The overall assembly...
