specific Embodiment approach 1
[0011] Specific embodiment one: the steps of the preparation method of this embodiment are as follows:
[0012] Step 1, pouring the high-strength or ultra-high-strength concrete core column 4, when the high-strength or ultra-high-strength concrete core column 4 is hardened;
[0013] Step 2, binding steel bars 2 on the periphery of the high-strength or ultra-high-strength concrete core column 4, then setting up the formwork and pouring the outer ordinary concrete column 1;
[0014] Step 3: After curing and removing the formwork, a reinforced concrete column with a built-in high-strength or ultra-high-strength concrete core column is formed.
specific Embodiment approach 2
[0015] Specific embodiment 2: This embodiment is described in conjunction with FIG. 1. In this embodiment, the cross-section of the ordinary reinforced concrete peripheral column 1 is a rectangular ring and the ring cavity of the ordinary reinforced concrete column 1 of the rectangular ring is built-in and runs through the ordinary reinforced concrete peripheral column. 1. The cross-section in the longitudinal direction is made of high-strength or ultra-high-strength concrete core column 4, and the cross-section is a rectangular ring. Ordinary reinforced concrete peripheral column 1 is composed of steel bar 2 and concrete 3.
[0016] 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 3
[0017] Specific Embodiment Three: This embodiment will be described in conjunction with FIG. 2 . This embodiment consists of a common reinforced concrete peripheral column 1 with a rectangular ring in cross section and a high-strength or ultra-high-strength high-strength or super-high-strength column that runs through the ordinary reinforced concrete peripheral column 1 with a circular cross-section in the length direction of the rectangular ring. The concrete core column 4 is made, and the cross section is a rectangular ring, and the ordinary reinforced concrete peripheral column 1 is composed of steel bars 2 and concrete 3 .
