Description

[Detailed description of the invention] This invention combines and connects multiple unit panels to each other,
It relates to a unit panel that can constitute each wall surface of a tank, and facilitates the production of irregularly shaped tanks in which the planar or vertical shape of the assembled tank is continuous, concave, or convex, other than square or rectangular. The present invention relates to an assembly unit panel that can be assembled.

In general, an irregularly shaped tank constructed by assembling unit panels means that there are obstacles such as pillars, beams, ducts, and piping in the installation space of the tank, as shown in Figures 1 to 3. The tank is formed into a concave, convex, or L-shape so as not to interfere with the tank.

The unit panel conventionally used for assembling the A part of the irregularly shaped tank as shown in Figs. 1 to 3 is the L-shaped unit panel 1 as shown in Figs. 4 and 5. there were.

This L-shaped unit panel 1 is assembled and used as shown in FIG. 6, which shows a perspective view of an irregularly shaped tank, and FIG. 7, which shows a cross-sectional shape taken along line A-A in FIG.

The L-shaped unit panel 1 shown in FIG.
After cutting off the ′′, they are made by joining each other at right angles.

The L-shaped unit panel 1 made in this way has the sixth
As shown in the figure, it is used to constitute the wall surface of the irregularly shaped part of the irregularly shaped tank, and the other wall surfaces are constituted by the basic unit panel 3.

As shown in FIG. 7, the L-shaped unit panel 1 and the basic unit panel 3 are connected by two sets of bolts 13 via a packing 11 and a connecting fitting 12.

When assembling an irregularly shaped tank using such a conventional L-shaped unit panel 1, there were the following drawbacks.

■ To make an L-shaped unit panel, it is necessary to cut off the upright joint edges of the basic unit panel once completed, and then join them back together to integrate them, so there is no waste in the materials used. It's a lot of work and complicated.

■As mentioned above, since it is manufactured by post-processing, the accuracy of the perpendicularity and external dimensions of the mating part is not as good as that of a product molded in one piece, which is not desirable in terms of quality.

■ If water enters the tank, a large load will be applied to the area where the L-shaped unit panels meet, but since both basic unit panels are interrupted at this area, the strength is weak.

■ In order to connect the L-shaped unit panel and the basic unit panel, two gaskets, connection fittings, and two sets of bolts are required, which increases the number of parts and complicates assembly work. do.

One possible way to solve the above drawback is to integrally mold the L-shaped unit panels shown in Figure 4.
Since the upright joining edges 6, 6' are undercuts, they cannot be removed from the molding layer mold and cannot be molded by normal molding methods, and there is also the above-mentioned drawback (2), so they have hardly been used.

The present invention was devised in view of the above-mentioned drawbacks, and is aimed at dramatically improving the assembly workability and strength of irregularly shaped tanks.

An embodiment of the present invention will be described below with reference to FIGS. 8 to 10.

FIG. 8 shows the shape of the L-shaped unit panel 4 of the present invention, which has two orthogonal rectangular pressure receiving surfaces 7° 7'.
An upright joining edge 10 that stands at least upright with respect to the respective pressure receiving surfaces 7, 7' is provided on the other peripheral edges other than the two edges 9, 9' parallel to the ridge line 8 formed by the meeting of these two pressure receiving surfaces.
．． 10' facing inward and integrally formed.

Although not shown, an inclined joint edge may be provided between the upright joint edge and the pressure receiving surface.

Therefore, the present invention has a structure in which no upright joint edges are provided on the two edges parallel to the ridgeline formed by the meeting of pressure-receiving surfaces, so that the product shape is not undercut and can be formed integrally, resulting in improved molding workability. In addition, the strength of the ridgeline where the two pressure-receiving surfaces meet is improved, and the accuracy of product dimensions is also improved.

Also, as is clear from the cross-sectional view in Figure 10, the parts required to connect the L-shaped unit panel and the basic unit panel are one packing and one set of bolts, so there are fewer parts than in the past. It is possible to significantly reduce the amount of damage, dramatically improve assembly workability, and streamline work.

Furthermore, since no upright joining edges are provided on the two edges parallel to the ridgeline formed by the pressure-receiving surfaces coming together, the width dimension W can be freely cut to match the dimensions of the irregularly shaped part of the irregularly shaped tank, as shown in Figure 8. Due to the adjustable nature of the mold, it is possible to form irregularly shaped parts of various sizes using a single mold.
