Construction process of H-shaped steel concrete transfer beam-reinforced concrete column joint

Abstract

The invention relates to a construction process of an H-shaped steel concrete transfer beam-reinforced concrete column joint. The construction process comprises the following steps: (1) designing thejoint in a detailed manner; (2) processing, manufacturing and mounting steel ribs of a H-shaped steel concrete transfer beam; (3) welding and fixing beam side die reinforcing bolts and a steel beam web plate; (4) erecting a support frame body; (5) laying a beam bottom template; (6) installing beam bottom longitudinal steel bars ; (7) hoisting a steel beam; (8) mounting steel bars on the peripheryof the steel beam and welding draw hooks; (9) mounting concrete column reinforcing steel bars at the joints; (10) mounting and reinforcing a beam side form; (11) pouring concrete; (12) curing concrete. The construction process has the advantages that the problems of staggered arrangement and connection of column main reinforcements, stirrups and structural steel at the H-shaped steel concrete conversion beam-reinforced concrete column combined joint are effectively solved; the engineering quality and the joint bearing capacity are ensured; the structural design requirement is met; the construction process is simplified; and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a construction technique of H-shaped steel concrete transfer beam-reinforced concrete column joints. Background technique [0002] Shaped steel concrete structure is a composite structure in which shaped steel is embedded in reinforced concrete. It is an organic whole formed of concrete, shaped steel, steel bars, and stirrups after pouring concrete with appropriate amount of horizontal and vertical reinforcement around the shaped steel. Due to the addition of section steel in reinforced concrete, section steel, with its inherent strength and ductility, and the integrated work of section steel, steel bar, and concrete, make section steel concrete structures have greater bearing capacity, greater rigidity, and seismic performance than traditional reinforced concrete structures. good points. Compared with the steel structure, the steel concrete structure has...
