DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the outline of a pillar forming apparatus according to the present invention. In FIG. 1, reference numeral 1 indicates a foundation pipe column.

As can be seen from FIG. 1, the base pipe pillar 1 has its base end portion 2 buried in the ground 12 and is erected substantially vertically. Reference numeral 3 denotes a joint pipe column, and the plurality of joint pipe columns 3 ... Are formed as pipes having a diameter larger than that of the basic pipe column 1. These joint pipe pillars 3 ... Are laid on the outside of the base pipe pillar 1, for example, and below the respective pipe pillars 1, 3,
Packing material 4 for preventing air leakage between the outer peripheral surface of 3
Is provided, and an integrated sealing portion 5 is formed inside the plurality of pipe columns 1, 3, and 3 (see FIG. 3).

The outermost joint pipe 3 is arranged.
Has its upper end face closed. Further, reference numeral 6 is an air introduction port, and the air from the air introduction device is introduced into the pipe column through the introduction port 6.

Reference numeral 7 is a roofing material, which is installed on the upper end of the joint pipe column 3 arranged on the outermost side. In the above, as understood from FIG. 1, the air as the pressure body 10 is introduced into the sealed portion 5 through the air introduction port 6. Here, what is introduced into the hermetically sealed portion 5 is not limited to air, and various gases, fluids, semi-fluids, or the like may be used.

The introduced air is compressed in the hermetically sealed portion 5, and the air pressure causes the joint pipes 3 ... Stacked in multiple layers on the base pipe column 1 to expand upward (arrow F in FIG. 2). reference). The extension of the pipe pillar by the introduction of air is performed at least by the pipe pillars which are erected at the four corners which are the basic pillars of the structure.

The extension of the pipe columns at the four corners must be performed at almost the same speed. Otherwise, the roofing material 7 installed on the upper part will be inclined. Therefore, in order to control the rising speed of the pipe pillar, as understood from FIG. 2, the chain block-shaped regulating member 8 is attached to the joint pipe pillar 3 arranged at the outermost side, and the pipe pillars installed at the four corners have the same speed. It is controlled to rise at.

FIG. 2 shows a state in which the columns of the structure are erected. In this state, as shown in FIG. 3, the pipe columns are fixed by welding 11 or the like.

As can be seen from FIG. 4, the installation surface 2
0 is a height adjusting member 21, and a holding member 22 is provided on the outer periphery thereof.
However, the foundation pipe column 1 is provided with a rotation mechanism 23, and the boundary between the foundation pipe column 1 and the joint pipe column 3 is provided with a support mechanism 24. This means is constructed because the pipe pillar used in the present invention is extremely heavy (for example, 40 to 70).
It is difficult for one worker to assemble a pipe column, and a scaffold is required when assembling it, and it is dangerous to work at a high place on this scaffold. This is to facilitate.

The height adjusting member 21 is formed of a jack or the like, and finely adjusts the height of the pipe column when it reaches a predetermined height.

The holding member 22 is formed of a tripod or the like, and a rotating mechanism 23 composed of a support shaft 23B and an annular member 23A is provided on the upper end side of the holding member 22, and the foundation pipe pillar 1 is attached to the annular member 23A with a bolt 23C and a nut 23D. The base pipe column 1 can be rotated around the support shaft 23B by fixing the base pipe column 1 (see FIG. 4).

The support mechanism 24 has a support pin 24A and a recess 24B for receiving the support pin 24A, so that the support pipe 24 does not come off from the foundation pipe column 1 even if the joint pipe column 3 rises (FIG. 1).
1).

Further, as can be seen from FIG. 8, a packing member 4 for preventing air leakage is joined to the gap between the base pipe column 1 and the joint pipe column 3 by a welding 4F, a locking member 4A, 4B, so that the pipe pillar 1
An integral sealing part 5 is formed in and 3 (see FIG. 5).

Further, as understood from FIG. 11, the support mechanism 24 is covered with a cover 24C, and the cover 2
From 4C, the wire 24J fixed to the support pin 24A by the screw 24L hangs down via the roller 24D, and the grip portion 24K is held in the hand to operate the wire 24.
The insertion operation of the support pin 24A can be controlled from the outside.

Reference numeral 24E is a leaf spring, which is fixed to the mounting member 24H of the foundation pipe column 1 by a screw 24G to press the support pin 24A, and when the wire 24J is loosened, the support pin 24A gradually moves into the recess 24B. Accepted by. Also,
The contact member 24M and the mounting member 24H of the support pin 24A are
Each is joined by welding 24F.

As can be seen from FIG. 12, a rod-shaped plate 51 is provided on the outer surface of the base pipe column 1 and the joint pipe column 3 is formed.
The guide projection 53 of the rod-shaped plate 51 is provided on the inner surface of the
A and 53B are provided respectively so that the support pin 24A is not displaced with respect to the recess 24B. In the present invention of FIG. 4 configured as described above, first, the height adjusting member 21 is placed on the installation surface 20, and the holding member 22 is set up on the outer periphery of the height adjusting member 21, so that the foundation pipe pillar 1 is slanted to the annular member 23A. Insert (arrow A) and fix with bolts 23C and nuts 23D (see FIGS. 4 and 9).

Next, the large catch 30 is fixed to the top of the joint pipe column 3 with bolts 31 and nuts 32, and the joint pipe column 3 is inserted into the inclined base pipe column 1 (see FIG. 4).
(Refer to arrow B), and is fixed by the support pin 24A so as not to fall off from the foundation pipe pillar 1.

In this state, the annular member 23A is rotated counterclockwise (see arrow C in FIG. 4) to stand the pipe columns 1 and 3 vertically and loosen the bolt 23C to loosen the pipe column 1.
The foundation pipe pillar 1 and the height adjusting member 21 are joined by lowering the whole 3 (see FIG. 5).

In this combined state, as understood from FIG. 7, the bottom portion 1A of the foundation pipe column 1 and the upper portion 21A of the height adjusting member 21 are fixed by bolts 41 and nuts 42,
The screw 21B of the height adjusting member 21 is engaged with the base pipe column 1.

After assembling the basic pipe column 1 and the joint pipe column 3 in this way, the wire 24 is pulled with the grip portion 24K in the hand and the support pin 24A is pulled out from the recess 24B. When the air 10 is introduced into the closed portion 5 through the mouth 6, the joint pipe column 3 rises (see arrow D in FIG. 6). When the air pipe 10 rises to near a predetermined height, loosen the wire 24 and slowly raise it. Support pin 24A
Is inserted into the recess 24B.

Finally, the height adjusting member 21 adjusts the height of the joint pipe column 3 to complete the work.

As understood from FIG. 13, the balloon 60 is housed in the foundation pipe pillar 1 and communicated with the air inlet 6 (see FIG. 13A), and the air 10 is introduced into the balloon 60.
The pipe columns 1 and 3 can also be erected vertically by inserting and inflating them (see FIG. 13B).

In the embodiment shown in FIG. 13, a packing material 4 for preventing air leakage is provided between the base pipe column 1 and the joint pipe column 3 (see FIG. 8).
There is an advantage that the sealed portion 5 can be formed without providing (see), and the balloon 60 may be a tubular one made of, for example, an airtight film.
