イルの製造方法を提供せんとするものである。 As shown in the vertical cross section of the conventional steel pipe concrete composite pile 1 in FIG. A thick-walled through-hole disk 5 with a groove 4 for connection is fitted inside and welded 6, 7, and a through-hole disk 8 is fitted inside on the upper side (arrow side) and welded 9. , each through-hole disk 5,
Concrete is poured between 8 and the perforated disc 5,
In order to weld the through-hole discs 5, 8 on the steel pipe 2, it is necessary to remove the rust around the welded parts. Work, slight modification work to match the through-hole disks 5, 8 to the inner hole of the steel pipe 2, temporary welding work of the inserted through-hole disks 5, 8, welding work, finishing work of weld beads, etc. Bevel part 4
The finishing work to correct the weld bead near the groove 4 into a concave shape requires considerable skill and man-hours. The labor cost accounts for a large proportion of the manufacturing cost of steel pipe concrete composite piles. After the concrete portion 12 is formed, the perforated disk 5
is no longer needed when it is not used as a groove for connection welding, and the through-hole disk 8 is no longer needed because it is cut for the purpose of aligning the pile caps after the pile sinking work. Therefore, a technical problem arises that must be solved in order to easily remove the perforated disk 5 after concrete is poured, and the present invention has been proposed to solve this problem. , A wall thickness regulating plate having a through hole in the center for forming the wall thickness of the concrete part to be formed inside the steel pipe is formed into a U-shaped cross section, and further, bolts are inserted into the cylindrical part of the regulating plate at various places. A hole is provided, and a female thread is provided near the upper and lower ends of the steel pipe at a location facing the bolt insertion hole, so that the wall thickness regulating plate is externally fitted onto the end of the steel pipe. After fitting, the bolt insertion hole and the female thread part are made to face each other and fixed with bolts, and then concrete is poured between the upper and lower wall thickness regulating plates and after hardening, the wall is fixed. It is an object of the present invention to provide a method for manufacturing a steel pipe concrete composite pile in which the thickness regulating plate is removed.

In the figure, 13 is a steel pipe, and its thickness is not particularly limited. Female threaded portions 14, 14 are provided at various places around the upper and lower ends of this steel pipe 13.
...is provided. Furthermore, a wall thickness regulating plate 15 having a U-shaped cross section is provided which can be fitted from the outer surface of the opening at the end of the steel pipe 13. Although this wall thickness regulating plate 15 is formed of a steel plate, the thickness of the plate should not be limited. A through hole 16 is provided in the center of the wall regulating plate 15, and concrete is placed between the through hole 16 and the inner wall surface of the steel pipe 13 to regulate the thickness of the concrete. Therefore, this wall thickness regulating plate 15 can be formed to a size that just fits tightly into the end of the steel pipe 15. Further, insertion holes 18, 18, . . . for bolts 17, 17, .

For example, after steam curing at normal temperature and pressure or autoclave curing, the wall thickness regulating plates 15, 15 are fixed to the bolts 17, 17...
By releasing and removing it, the steel pipe concrete composite pile is completed.

ある。 As detailed in the above embodiment, the method for producing a steel pipe concrete composite pile according to the present invention includes fitting the cylindrical portion of the wall thickness regulating plate having a U-shaped cross section onto the upper and lower ends of the steel pipe, Then, the bolt insertion hole provided in the cylindrical portion of the wall thickness regulating plate is opposed to the female threaded portion provided near the upper and lower ends of the steel pipe, and here,
Insert bolts from the outside and tighten the wall thickness regulating plate to the steel pipe. After that, concrete is poured between the wall thickness regulating plates, and after this concrete part has solidified, the wall thickness regulating plates are removed. To,
Since the cylindrical portions of each tube are fitted onto the outside, and bolts are inserted from the outside surface and tightened, the wall thickness regulating plate can be easily removed from the steel pipe by unscrewing the bolts. Therefore, there is no need for the conventional work of welding a through-hole disk to the steel pipe or finishing the groove with a grinder, and the wall thickness regulating plate can be used repeatedly, which also contributes to cost reduction. It is.
