Locally reinforced fabricated concrete structure and construction method thereof

Abstract

The invention discloses a locally reinforced fabricated concrete structure and a construction method thereof. The fabricated concrete structure comprises a fabricated concrete structure body, reinforcing ribs connected to at least one ends of vertical ribs in the fabricated concrete structure body, and a grouting sleeve connected between the adjacent reinforcing ribs of the fabricated concrete structure body. The diameter of the reinforcing ribs is larger than the diameter of the vertical ribs, and the reinforcing ribs are symmetrically arranged in the length direction of the fabricated concrete structure body. The fabricated concrete structure further comprises anti-shearing pieces connected to one side of the fabricated concrete structure body and anti-shearing grooves corresponding to the shearing pieces. According to the locally reinforced fabricated concrete structure, during construction, through the arrangement of the reinforcing ribs, the strength and anti-pulling capacity of the connection vertical ribs at the joints are improved; the grouting sleeve is arranged to facilitate grouting and make up the strength loss at the joints; through the arrangement of the anti-shearingpieces and the anti-shearing grooves, the shearing resistance at the connecting horizontal plane can be ensured, and the integrity of the structure is improved; and through the arrangement of a sealing layer and a damping cushion, the integrity of the fabricated concrete structure during connection is facilitated, and the anti-seismic performance is improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, in particular to a partially reinforced prefabricated concrete structure and a construction method thereof. Background technique [0002] With the development of the construction field, prefabricated buildings, as an important form in building construction, have been greatly promoted and applied. In the construction of prefabricated buildings, the main structural forms are prefabricated concrete wall panels and prefabricated concrete columns; usually in the construction of prefabricated concrete structures, the joints are connected by grouting sleeves to form the designed structural system; but in construction , the steel bars at the connecting sleeves are prone to load loss, and the grouting at the joints of the prefabricated concrete structure is not easy to be full, and the shear bearing capacity of the horizontal connecting surface is low, especially, the ductility...
