[0001] The invention relates to the technical field of steel-bamboo composite columns, and in particular to a steel-bamboo composite column and a construction method thereof. Background Art

[0002] Steel bamboo is a very common bamboo plant nowadays. In the process of building steel bamboo landscape architecture, it is usually necessary to manually bundle multiple groups of steel bamboo together and finally build them into a building frame. Since most of the current steel bamboos are integrated structures and have a relatively heavy weight, it is not conducive to people's construction work. Summary of the invention

Thus, a stable connection of each component is achieved.

[0006] Preferably, through holes are provided around the second socket, so that the third bolt can pass through the upper steel column.

[0007] Preferably, the connecting piece is in a cross-shaped structure. Accordingly, the cross-shaped connecting piece can connect upper steel columns in different directions.

[0008] Preferably, a reinforcement device is provided between the lower steel columns, and the reinforcement device includes a reinforcing rib, the reinforcing rib is provided between the lower steel columns, both ends of the reinforcing rib are provided with a knob, both sides of the knob are provided with a limit block, a torsion spring is provided between the knob and the reinforcing rib, and a through groove is provided on the surface of the lower steel column at the position of the reinforcing rib, and both sides of the through groove are provided with a notch. Accordingly, the reinforcing rib can improve the strength of multiple groups of lower steel columns.

[0009] Preferably, the surface of the through-groove is further provided with a second positioning groove, and the surface of the reinforcing rib is further provided with a second positioning block, thereby preventing the reinforcing rib from rotating in the through-groove.

[0010] Preferably, a positioning device is provided on the surface of the concrete base, and the positioning device includes a positioning column, and the positioning column is fixedly installed around the concrete base, and a positioning hole is opened on the surface of the embedded part at the position of the positioning column. Accordingly, it is convenient for people to install the embedded part.

[0011] Preferably, the diameter of the positioning column is the same as the diameter of the positioning hole. Accordingly, the concrete base can be stably connected to the embedded part.

[0012] A method for constructing a steel-bamboo composite column comprises the following steps:

[0013] Step 1: First, cast the embedded part on the concrete base, then tighten the No. 5 bolt into the No. 5 screw hole to fix the embedded part, then insert the sleeve into the embedded part and adjust it to a suitable angle, then tighten the No. 1 bolt into the No. 1 screw hole to connect the sleeve to the embedded part;

[0014] Step 2: Then insert the bottom end of the lower steel column into the No. 1 socket of the sleeve, and then tighten the No. 2 bolt into the No. 2 screw hole.

[0037] A method for constructing a steel-bamboo composite column comprises the following steps:

[0038] Step 1: First, cast the embedded part 2 on the concrete base 1, then tighten the No. 5 bolt 28 into the No. 5 screw hole 29 to fix the embedded part 2, then insert the sleeve 3 into the embedded part 2 and adjust it to a suitable angle, then tighten the No. 1 bolt 4 into the No. 1 screw hole 5 to connect the sleeve 3 to the embedded part 2;

[0039] Step 2: Then insert the bottom end of the lower steel column 7 into the No. 1 socket 6 of the sleeve 3, and then tighten the No. 2 bolt 8 into the No. 2 screw hole 9. At this time, the lower steel column 7 is fixed to the sleeve 3. Then insert the connecting piece 15 between the multiple groups of upper steel columns 12, so that the two protruding ends of the connecting piece 15 are docked in the No. 2 socket 18 at one end of the upper steel column 12, and then insert the No. 4 bolt 16 into the designated through hole 19 and then tighten it into the No. 4 screw hole 17. At this time, it plays the role of connecting the multiple groups of upper steel columns 12;

[0040] Step 3: Then place multiple groups of upper steel columns 12 on the notch at the top of the lower steel column 7, and then tighten the No. 3 bolts 13 in the No. 3 screw holes 14 to fix the lower steel column 7 and the upper steel column 12. Finally, just splice multiple groups of upper steel columns 12 in the same way to form a building frame.

[0041] Working principle: In actual use, by setting the concrete base 1, embedded part 2, sleeve 3, No. 1 bolt 4, No. 1 socket 6, lower steel column 7, No. 2 bolt 8, No. 1 positioning block 10, No. 1 positioning groove 11, upper steel column 12, No. 3 bolt 13, connecting part 15, No. 4 bolt 16, No. 2 socket 18 and No. 5 bolt 28, first cast the embedded part 2 on the concrete base 1, then tighten the No. 5 bolt 28 into the No. 5 screw hole 29 to fix the embedded part 2, then insert the sleeve 3 into the embedded part 2 and adjust it to a suitable angle, then tighten the No. 1 bolt 4 into the No. 1 screw hole 5 In the process, the sleeve 3 is connected to the embedded part 2, and then the bottom end of the lower steel column 7 is inserted into the No. 1 socket 6 of the sleeve 3, and then the No. 2 bolt 8 is tightened in the No. 2 screw hole 9. At this time, the lower steel column 7 is fixed to the sleeve 3, and then the connecting piece 15 is inserted between the multiple groups of upper steel columns 12, so that the two protruding ends of the connecting piece 15 are docked in the No. 2 socket 18 at one end of the upper steel column 12, and then the No. 4 bolt 16 is inserted into the specified through hole 19 and then tightened into the No. 4 screw hole 17, which plays the role of connecting multiple groups of upper steel columns 12. Then, the multiple groups of upper steel columns 12 are placed on the notch at the top of the lower steel column 7, and then the No. 3 screw The bolt 13 is locked in the No. 3 screw hole 14 to fix the lower steel column 7 and the upper steel column 12. Finally, multiple groups of upper steel columns 12 can be spliced ​​in the same way to form a building frame. In actual use, by setting a reinforcement device, after the lower steel column 7 is built, the knob 21 at one end of the reinforcing rib 20 can be rotated to make the limit block 22 on its side flush with the notch 27, and then the No. 2 positioning block 24 on the surface of the reinforcing rib 20 is aligned with the No. 2 positioning groove 25 and finally inserted into the through groove 26. When the knobs 21 at both ends of the reinforcing rib 20 are located at the positions on both sides of the lower steel column 7, the rotation is stopped at this time. The knob 21 and the torsion spring 23 drive the knob 21 to reset and thus stagger the positions of the limit block 22 and the recess 27. At this time, the reinforcing rib 20 cannot be separated from the lower steel column 7, which plays the role of installing the reinforcing rib 20, and the reinforcing rib 20 increases the strength between the lower steel column 7. In actual use, by setting a positioning device, in the process of docking the embedded part 2 and the concrete base 1, it is only necessary to preliminarily dock the positioning hole 31 on the embedded part 2 with the positioning column 30. At this time, the No. 5 screw hole 29 on the surface of the embedded part 2 and the concrete base 1 is aligned, which is convenient for people to use the No. 5 bolt 28 to lock and fix the embedded part 2.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
