Embodiment 1
[0028] Such as figure 1 , figure 2 A columnar structure with opening stiffeners and filled with steel fiber concrete is shown, including square steel pipes 1 arranged vertically, and a plurality of vertical stiffeners arranged on the four inner walls of square steel pipes 1 respectively. 2 and a steel fiber concrete column 3 poured from steel fiber concrete filled in the inner lower part of the square steel pipe 1, the steel fiber concrete column 3 fastens and connects the square steel pipe 1 with a plurality of vertical stiffeners 2 as a whole , the structures and dimensions of the plurality of vertical stiffeners 2 are the same, the laying direction of the plurality of vertical stiffeners 2 is consistent with the direction of the central axis of the hollow steel pipe 1 and the laying of the plurality of vertical stiffeners 2 on the same level. The four inner side walls of the square steel pipe 1 include a left side wall and a right side wall symmetrically arranged on the ...
Embodiment 2
[0040] In this embodiment, the difference from Embodiment 1 is that the cross section of the square steel pipe 1 is rectangular, L1>L2, and the number of the plurality of vertical stiffeners 2 is 4-10.
[0041] Such as image 3 As shown, in this embodiment, the number of multiple vertical stiffeners 2 is 6, wherein N1=2, N2=1, during actual processing and manufacturing, multiple vertical stiffeners can be used according to actual specific needs The number of ribs 2 is adjusted accordingly.
[0042] In this embodiment, the rest of the structures, connections and manufacturing processes are the same as those in Embodiment 1.
