Embodiment Construction

[0037] The construction method of the special-shaped steel pipe column reinforced concrete ring beam of the present invention will be described in detail below.

[0038] The technical principle of the special-shaped steel pipe column reinforced concrete ring beam construction method of the present invention:

[0039] The steel pipe concrete column is connected with the reinforced concrete beam, and the joint treatment adopts the beam-column joint treatment method of the circular corbel. When the steel pipe column is processed, the corresponding steel corbel is added. The steel corbel is welded by 22mm thick steel plate. The ring beam and the frame beam are tied up, the main reinforcement of the beam is anchored into the inner main reinforcement of the ring beam, and the frame beam and floor concrete are poured. Since the steel corbel is located in the middle of the ring beam, and the lower main bars of the ring beam are located on the inner side of the rigid corbel, the ring b...

Abstract

The invention provides a special-shaped steel pipe column reinforced concrete ring beam construction method and belongs to the technical field of building construction. The construction method comprises the steps that a steel pipe concrete column is connected with a reinforced concrete beam; a beam-column joint processing method of an annular bracket is adopted by joint processing; a corresponding steel bracket is additionally arranged during machining of the steel pipe column, specifically, the steel bracket is formed by welding a steel plate which is 22 mm thick; a ring beam and a frame beam are bound to the steel bracket; main steel bars of the beam are anchored into main steel bars of the inner side of the ring beam; and concrete of the frame beam and a slab are poured. Due to the facts that the steel bracket is located in the middle of the ring beam, and the main steel bars of the lower row of the ring beam are located on the inner side of the steel bracket, ring beam steel bars cannot be bound on a machining site and then suspended like a conventional ring beam, and an on-site binding construction mode is adopted. Through practice examination of the method in engineering, the installation problem of ring beam joint steel bars is solved; and according to the method, safety is guaranteed, the construction quality is good, the speed is high, the comprehensive construction cost is low, and the economic benefits and social benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a special-shaped steel pipe column reinforced concrete ring beam. Background technique [0002] In general, as a composite structure that can make full use of the characteristics of steel and concrete materials, the steel tube concrete column has been widely used in engineering, which improves the technical rationality and economic superiority. However, as an important beam-column joint in CFST columns, it has evolved from the relatively single connection between steel beams and CFST columns or the connection between reinforced concrete beams and CFST columns in the past to a CFST column joint that has both reinforced concrete beam connections and rings. Beam connection, its stress and structure are complex. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art and...
