Abstract

The invention discloses a bolt connecting prefabricated concrete frame structure which comprises a plurality of prefabricated concrete columns, a plurality of prefabricated concrete beams, a pluralityof prefabricated concrete plates, post-cast concrete overlapping layers, a plurality of post-cast concrete beam connecting joint areas and column leg grouting areas, the bottom prefabricated concretecolumns are vertically arranged on the ground according to lines, each prefabricated concrete beam is arranged on two adjacent prefabricated concrete columns of each line, the prefabricated concreteplates are arranged on two opposite prefabricated concrete beams, the post-cast concrete overlapping layers are arranged on the prefabricated concrete plates, concrete beam connecting joint area modules are mounted in the post-cast concrete beam connecting joint areas to cast a connecting joint area, a plurality of connectors of the upper prefabricated concrete columns are connected with a plurality of upper bolts of the lower prefabricated concrete columns through a plurality of nuts, and gaps among the upper prefabricated concrete columns and the post-cast concrete overlapping layers are grouted by the column leg grouting areas.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a bolt-connected prefabricated concrete frame structure. Background technique [0002] The prefabricated concrete frame structure has fast construction speed, good quality, and can save a lot of formwork and supports. It has significant energy saving and emission reduction characteristics. At the same time, it can realize large spans and meet the requirements of users with large bays. It is a structural form that meets the needs of industrialized building development. . [0003] The connection of prefabricated columns in the existing precast concrete frame structure system usually adopts sleeve grouting connection or grout anchor lap connection. The sleeve grouting connection is to insert the reserved steel bars of the prefabricated lower column into the pre-embedded sleeve in the prefabricated upper column, and pour high-strength non-shrinking cement morta...
