specific Embodiment approach 1

[0023] Specific implementation mode one: combine Figure 1 to Figure 7 Describe this embodiment, a corrugated steel pipe reinforced concrete column of this embodiment, it includes a column body 1-1 and two reinforced concrete beams 1-2, the two reinforced concrete beams 1-2 are perpendicular to each other to form a plane, and the Said plane is horizontally installed on the vertical column 1-1;

[0024] The column 1-1 includes a corrugated steel pipe 2-1, concrete 2-7 and a reinforcement cage 2-9 inside the column. The corrugated steel pipe 2-1 is provided with four corrugated steel pipe reserved holes 2-8 in a circular array along the outer circumference direction. The inner reinforcement cage 2-9 is installed in the corrugated steel pipe 2-1, and the concrete 2-7 is poured in the corrugated steel pipe 2-1;

[0025] Each reinforced concrete beam 1-2 includes a steel reinforcement cage 2-10 in the beam and two sets of guide steel plates. It is installed on two sets of guide s...

specific Embodiment approach 2

[0028] Specific implementation mode two: combination figure 2 Describe this embodiment, the reinforcement cage 2-9 in the column of this embodiment comprises a plurality of longitudinal reinforcement bars 2-5 in a column and a plurality of stirrup bars 2-6 in a column, and the longitudinal reinforcement bars 2-5 in a plurality of columns are vertically arranged in a circular array. Arranged vertically, multiple longitudinal steel bars 2-5 in the column are connected by multiple internal stirrup bars 2-6 installed from top to bottom. Such setting is convenient to provide a stronger guarantee for the corrugated pipe reinforced concrete column. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0029] Specific implementation mode three: combination figure 2 Illustrate this embodiment, the reinforcement cage 2-10 in the beam of this embodiment comprises a plurality of beam longitudinal reinforcements 2-2 and a plurality of beam middle stirrups 2-3, and a plurality of beam longitudinal reinforcements 2-2 are arranged in a rectangle. The longitudinal steel bar 2-2 of the root beam is connected by a plurality of stirrup bars 2-3 in the beam to form a reinforcement cage 2-10 in the beam. Such setting ensures the stability and firmness of the beam structure. Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention discloses a corrugated steel pipe reinforced concrete column, relates to a reinforced concrete column, and aims to solve a problem that beam-column connection nodes in a frame structure composed of existing steel pipe reinforced concrete columns and reinforced concrete beams are complex in stress, difficult in construction and unable to ensure performance under stress, and problems that a node core region in the frame structure composed of steel pipe restrained reinforced concrete columns and the reinforced concrete beams is not easy to realize a design principle of 'strong column, weak beam and stronger node', steel pipes are easy to bend, and columns are complex in construction. The corrugated steel pipe reinforced concrete column comprises a column body (1-1) and two reinforced concrete beams (1-2); the two reinforced concrete beams (1-2) are perpendicular to each other to form a plane; the plane horizontally penetrates the vertically arranged column (1-1). The corrugated steel pipe reinforced concrete column provided by the invention is used in the construction industry.

Description

technical field [0001] The invention relates to a reinforced concrete column, in particular to a corrugated steel pipe reinforced concrete column, which belongs to building structural components. Background technique [0002] Concrete is filled in the empty steel pipes and bears the external load together to form a new type of vertical force-bearing member, the steel pipe concrete column. Due to the interaction between the steel pipe and the core concrete, the deficiency of the two materials can be effectively compensated, so that the steel pipe concrete has anti-corrosion properties. It has superior mechanical properties such as high compressive bearing capacity, good ductility, and good seismic performance. It also has the characteristics of convenient construction and good economic performance. Therefore, it is favored by civil engineers and is increasingly widely used in engineering. The composite frame structure formed by steel-filled concrete columns and steel-concrete...
