Description

[Detailed Description of the Invention] This invention relates to an improvement in the reinforcing structure of an assembled tank.

In recent years, large containers such as tanks are often assembled from a large number of unit plates. Various types of unit boards are known, but a typical one is a right-angled rectangular board with joining edges protruding to the same side around the four peripheries. The bonding edge referred to here includes an upright bonding edge that is approximately perpendicular to the substrate, and an upright bonding edge that is approximately vertical to the substrate.
Beveled joint edges that slope at an angle of 135 degrees are known. In addition, as a unit plate, one is used that has both an inclined joining edge and an upright joining edge around the four peripheries of the substrate, and one that has only one of them.

When assembling a tank using the above unit plates, the unit plates are arranged on the same plane or in orthogonal directions to form the bottom and side walls, and the joints of the unit plates are L-shaped across the bottom and side walls. connected to extend.

A tank assembled in this way is usually fitted with a lid, but since the lid of a large tank is quite large, it tends to bend into the hollow. Therefore, a pillar was erected inside the tank to support the lid. This column was erected on the joint of the unit plates at the bottom. The reason for this was that the bottom joint had a joint edge that protruded downwards, which gave it great strength and was thought to be a convenient position to support the load.

On the other hand, when the tank was filled with liquid, the side walls tended to bulge outward. As one means to prevent this deflection, it was considered to diagonally support the space between the bottom and the side wall with a stay. In this case, it was considered preferable that both ends of the stay be positioned and fixed on the joints of the unit plates in the bottom and side walls. The reason for this is that at the joint, the joining edge acts as a rib, so the deflection of the unit plate is small.
This was because it was considered a convenient position for support.

However, when the straight line closing the fixing positions at both ends of the stay intersects with the pillar, the stay cannot be fixed as described above. In this case, it was necessary to fix both ends of the stay away from the joint in order to avoid the pillars. However, fixing both ends of the stay at a position away from the joint creates an imbalance in the forces applied to the unit plates, which has the disadvantage that the unit plates are likely to be destroyed.
This invention was made in an attempt to improve the above-mentioned drawbacks.

That is, this invention uses a shallow box-like body formed by providing joint edges protruding to the same side on the four peripheries of a right-angled substrate as a unit plate, and connects the unit plates in the same plane and orthogonal directions to form a bottom. In a tank in which the joint of the unit plate is extended in an L-shape across the bottom and the side wall, and a pillar is erected on the bottom and the joint, a stay is inserted between the bottom and the side wall, and the stay is Intersect with the pillar and divide it at the position of the pillar, fix the divided ends to the pillar, fix both ends of the stay on the joints of the bottom and side walls, and connect the stay fixing part on the pillar to the straight line that fills both ends of the stay. It is a reinforced assembled tank located on top.

The reinforced assembled tank according to this invention will be explained as follows based on the drawings. Figure 1 shows
