Embodiment Construction

[0018] Specific embodiments are given below in conjunction with the accompanying drawings, and the TRC pipe-constrained reinforced concrete column and the manufacturing method of the present invention will be described in detail.

[0019] like figure 1 Shown is a schematic structural diagram of a TRC-constrained reinforced concrete column, which includes a TRC pipe 1 and a reinforced concrete column 2 cast in the TRC pipe. Determine the cross-sectional form of the column according to the architectural design (circular ( figure 1 a), square ( figure 1 b)) and height, configure longitudinal bars 5 and spiral stirrups 6 according to the structural design (circular ( image 3 a), square ( image 3 b)).

[0020] In the factory, the woven mesh 3 is first placed in the mold for making the TRC pipe 1, and the prepared high-performance concrete 4 is poured to make the TRC pipe 1; the longitudinal reinforcement bars 5 and the spiral stirrups 6 are bound to form a reinforcement cage....

Abstract

The invention discloses a textile reinforced concrete (TRC) tube restraining reinforced concrete column which is characterized in that a TRC tube is prefabricated, the TRC tube is installed at a construction site, a reinforced cage is installed, concrete is poured, and the TRC tube restraining reinforced concrete column is formed. The TRC tube restraining reinforced concrete column is a novel assembled integrated type structure with the structure and a template integrated. The TRC tube restraining reinforced concrete column has the advantages that the characteristics of corrosion resistance, fire resistance and high thin wall intensity of the TRC are completely utilized, spiral stirrups are combined to increase restraint on the core concrete, and bearing capacity and anti-seismic performance of construction members are improved remarkably. The TRC tube is not only a construction template, but also a constituent part of the structure to join in work together, so that the TRC tube facilitates saving of large quantities of templates. The TRC tube restraining reinforced concrete column has the advantages of being simple in structure, convenient to construct, high in construction efficiency, low in cost, high in intensity, good in anti-seismic performance, fire-proof, durable and the like. Meanwhile, the TRC tube restraining reinforced concrete column facilitates saving of resources and energy sources and promotes development of building industrialization.

Description

technical field [0001] The invention relates to the field of civil engineering structures, in particular to a TRC pipe-constrained reinforced concrete column. . Background technique [0002] With the development of modern engineering structures in the direction of large-span, high-rise and heavy-duty, building materials and building structures must have good bearing capacity, ductility, durability and fire resistance, as well as meet the requirements of building industrialization. Confined concrete structures are an extremely effective composite structure. CFST columns and fiber reinforced plastic (FRP) confined concrete columns can give full play to the advantages of constraints and high-strength concrete, and have become one of the basic stress-bearing components commonly used at present due to their unique good bearing capacity and ductility. [0003] However, the CFST column components have high processing requirements, complex joint construction, poor fire resistance,...
