Can be assembled at the tank installation site.

By the way, in a tank for storing a liquid, a larger pressure is applied to the side wall 50 at a lower position. Therefore, in the above-described panel material assembly type tank, a panel material 51 that is thicker as the lower portion of the side wall 50 is used.

In assembling such a panel-assembled tank, a step is formed between vertically adjacent panel members 51, and as shown in FIG. 11, the inner wall surfaces 54 of both steps 52 are flush with each other. Like that.

[0005] When the panel members 51 match the predetermined positions, the panel members 51 are fixed by welding.

[0006]

However, in a large tank, the position adjustment is not easy because one panel member 51 becomes very large and heavy. Moreover, large tanks are often installed outdoors, and are assembled in an outdoor environment, so that the panel material 51 having a large area fluctuates due to the wind and its position is hard to be determined. For this reason, alignment has become more difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an assembling jig for a tank which facilitates assembling a tank side wall with a panel material.

The bolt insertion hole is supported parallel to the first bolt insertion hole at a position off the contact surface. Therefore, when a step is formed by a predetermined number of panel materials and a new step is sequentially formed on the upper side of the step to form a side wall, the panel forming the lower step already formed is formed. The bolt is erected vertically on the abutted surface with the outer surface of the material as the abutted surface. Then, when this bolt is inserted into the first bolt insertion hole and a nut is screwed into the tip of the bolt penetrating the first bolt insertion hole and tightened, the contact surface comes into pressure contact with the outer surface of the lower panel material. In this state, the base is fixed to the lower stage. At this time, the second bolt insertion hole of the support portion fixed to the base portion is disposed so as to be perpendicular to the panel material forming the upper step portion. A bolt is vertically erected on the outer surface of the panel material of the upper step portion facing the second bolt insertion hole, and the bolt passes through the second bolt insertion hole, and a nut is attached to the tip of the bolt. When screwed together and tightened, the upper panel material is moved and arranged on the support portion side. Therefore, the panel material forming the upper step portion is gradually moved outward by the engagement of the nut with respect to the panel material forming the lower step portion. as a result,
Positioning of the panel material forming the upper step with respect to the formed lower step is facilitated.

According to the invention described in claim 2, according to claim 1,
In addition to the effect of the invention described in the above, since the side surface on the contact surface side of the support portion is provided at a position retracted from the contact surface, the distance between the contact surface and the side surface on the contact surface side in the support portion Parts become unnecessary. Therefore, the assembly jig is configured with a smaller number of parts.

[0012] According to the third aspect of the present invention, the first aspect is provided.
Alternatively, in addition to the function of the invention described in claim 2, at least one of the first bolt insertion hole and the second bolt insertion hole is formed as a vertically long slot, so that each bolt is inserted into both bolt holes. Becomes easier.
