Abstract

PURPOSE: To make it possible to quickly and safely assemble a panel so that the panel may be welded to be an excellent shape by holding with clamps a leg for a flange material on the adjacent panel and by maintaining the space relationship to weld end portions of the panel each of which is reciprocally opposed. CONSTITUTION: Each flange material 2 disposed along the opposite end portions 18 and 20 of an adjacent panel 1 has near-legs 22 and 24 fixed on the panel 1 and horizontal legs 26 and 28 protruding from the panel 1. The horizontal legs 26 and 28 which are oppositely positioned are branched to the opposite direction from the opposite end portions 18 and 20. The horizontal legs 26 and 28 are held in opposite positions by a clamp material 30. The clamp material 30 maintains a space to reciprocally weld the opposite end portions 18 and 20 of the adjacent panel 1 and forms a connection seam between the end portions 18 and 20.

Description

BACKGROUND OF THE INVENTION The present invention relates generally to metal tanks, and more particularly to tanks utilized for liquid storage.

In constructing this type of tank, metal panels are first prepared. This is similar to a module formed by making two rectangular sections from a cylinder. These curved panels are then transported to the desired location and arranged in a ring-like configuration with the ends of the panels overlapping. These panels are then welded together and
Form a tank. However, such a process is cumbersome; after zero position determination, the panel moves from the correct welding position.

[Summary of the invention]

The present invention eliminates such drawbacks and includes adjacent panels disposed in an end-to-end relationship, with L-shaped flange members along opposite ends of the adjacent panels. Fixed. Each L-shaped flange member has a proximal leg secured to the panel.

It has lateral legs projecting from the panel.

The lateral legs of the flange members on adjacent panels diverge in opposite directions from opposite ends of the panels, but are adjacent in opposing relationship to each other. The lateral legs are maintained in this relationship by the fastening members and in this way the opposing ends of the panels maintain a spatial relationship for welding the ends of the panels together.

Further, in the present invention, the fastening member includes a member for adjusting the spatial relationship of opposing ends of adjacent panels.

Further, in the present invention, the panels are substantially identical and stacked before being installed in an end-to-end relationship.

It is therefore an object of the invention to provide an improved construction of a tank in which the panels used are homogeneous. Such homogeneity makes the panels less expensive and easier to transport.

Another object of the invention is to provide an improved construction of a tank in which the panels used can be assembled quickly and safely.

Yet another object of the invention is to provide a structure for a tank in which the panels forming the tank are placed and held in spatial relationship so that the panels are welded to a superior shape.

〔Example〕

Hereinafter, the present invention will be specifically explained in detail.

1 shows a perspective view of the panels stacked for transport, FIG. 2 shows a perspective view of the tank members separated from each other, and FIG. 3 shows a perspective view of the tank in an assembled state. , FIG. 4 shows a partial sectional view showing a method of connecting adjacent panels.

2 and 3 show a preferred example of a tank according to the invention for storing products such as liquids,
The panels l are connected to form a cylinder 12. The upper part 14 of the cylinder 12 is covered with a top panel 6 and the lower part 16 with a bottom panel 7. Panel 1, top panel 6 and bottom panel 7 are preferably made of metal.

FIG. 4 shows a substantially L-shaped flange member 2. FIG.

This is arranged along opposite ends 18.20 of adjacent panels 1, each flange member 2 having a proximal leg 22.24 fixed to the panel 1 and a lateral leg 26.28 projecting from the panel 1. have. Lateral leg 26.2

It branches out in opposite directions. Lateral leg 26.28
are held in opposing relationship by fastening member 30. The fastening member 30 is attached to the opposite end 18.2 of the adjacent panel l.
Maintain space for welding the 0's together. In FIG. 4, designation number 3 indicates the connecting seam between the opposing ends 18.20.

In the embodiment described above, the opposing lateral legs 26, 28 have a hole 4 which is dimensioned to allow the bolt 5 to pass loosely through it. Natsu 3 for Boruto 5
Tighten 2. In this way, the hole 4, bolt 5 and nut 32 are included in the fastening member 30. The exact relative position of 1126.28 in the opposing lateral direction is Naft 32
is adjusted by gradually tightening bolt 5. Naft 32
After substantially completely tightening, the opposing ends 18.20 are held in spaced relationship for welding.

As shown in FIG. 1, a preferred example of the panel 1 is of a curved, substantially identical shape. The panels 1 are stacked on top of each other before placing them in end-to-end relationship. Therefore, when transporting the panel 1 between the manufacturing site and the construction site of the tank 10, it is easier to handle if the panel 1 is made into a compact shape as shown in FIG.

As shown in FIG. 4, the preferred embodiment of the present invention utilizes a flange member 2 having internal ends 34,36. The flange member 2 is generally secured to the panel 1 by welding the inner ends 34, 36 to the panel 1. This results in the formation of a fastening seam 38.40 located approximately between the inner end 34.36 and the panel l.

Finally, in the preferred embodiment shown in FIG. 3, the flange member 2 is located on the outer surface 42 of the cylinder 12 formed by the panel 1.

In the above description, one embodiment of the present invention has been shown, but it goes without saying that changes, modifications, etc. can be made without departing from the scope of the present invention.

[Summary of the invention]

The present invention relates to the structure of metal tanks. The panels forming the tank are clamped in an end-to-end relationship along corresponding ends of the panels by flange members.

By tightening the flange members, the opposing ends are maintained in a spatial relationship for welding the opposing ends.
