specific Embodiment approach 1

[0007] Specific embodiment 1: This embodiment consists of a peripheral ordinary reinforced concrete column 1, which is composed of steel bars 2 and concrete 3. A high-strength or ultra-high-strength concrete core column 4 in the longitudinal direction of the reinforced concrete column 1 .

[0008] The function of the built-in high-strength or ultra-high-strength concrete core column 4 is mainly to bear the axial pressure, and the function of the peripheral reinforced concrete column 1 is mainly to bear the bending moment.

specific Embodiment approach 2

[0009] Specific Embodiment 2: This embodiment will be described in conjunction with FIG. 1 . In this embodiment, the outer cross-section of the column is a rectangular reinforced concrete column 1 and the core cavity of the rectangular outer ordinary reinforced concrete column 1 is built with a high-strength or ultra-high-strength concrete with a rectangular cross-section that runs through the length direction of the outer ordinary reinforced concrete column 1. Stem 4 is made.

Abstract

A reinforced concrete pile with super strength load concrete core includes a normal reinforced concrete shell and a super strength load concrete core of the same length with the shell. This could reduce the sectional area of the traditional pile and the consumption of reinforcing materials.

Description

technical field [0001] The invention relates to a reinforced concrete column in the field of civil engineering. Background technique [0002] In order to meet the requirements of concrete column bearing capacity and lateral (wind, earthquake) resistance, sometimes the cross-sectional size of the concrete column needs to be too large. The steel pipes of this type of column have to penetrate the joints of the structure, making it very difficult for the steel bars in the horizontal members to pass through the joints, which is not conducive to construction, and it is difficult to guarantee the quality of the project. Contents of the invention [0003] The present invention provides a built-in high-strength or ultra-high-strength concrete core column in order to solve the problem that the existing general reinforced concrete column has a large cross-sectional size and the joint construction between the reinforced concrete column and the horizontal member with a built-in steel t...
