A first aspect of the present invention is to connect a plurality of flat unit panels (4) each having a flange portion (3) on the periphery of a rectangular pressure receiving surface (1), bottom wall (5),
In a panel-assembled tank plate comprising a side wall (6) and a ceiling (7), a curved unit panel (8) is installed at a corner of the tank (US) that is orthogonal to the horizontal direction. It is characterized in that a flat part for attaching the partition is provided on the periphery of the vertical flange part.

The second invention of the present invention is a flat unit panel (4) in which a flange part (3) is provided on the periphery of a rectangular pressure receiving surface (1), and a plurality of flange parts (3) are connected to each other, bottom wall (5),
In a panel assembly type tank a9 formed with a side wall (6) and a ceiling wall (7), a pressure receiving surface of an arc-shaped panel connected to at least the bottom wall is provided at a corner portion of the tank (19) that intersects at right angles in the lateral direction. A curved unit panel has a substantially fan-shaped flat plate part (9) integrally provided perpendicular to the lower end of the panel, and a flange part (3) formed on the pressure receiving surface (1) and the periphery of the substantially fan-shaped flat plate part (9). It is characterized by being connected.

(Example) An example of the present invention will be described below based on FIGS. 1 to 6.

As shown in FIG. 1, reference numeral 8 denotes a flange portion at the peripheral edge of the pressure receiving surface 1 which is rectangular and horizontally curved at a center angle of curvature of 90 degrees toward the inside of the tank, and extends perpendicularly to the edge toward the outside of the tank. 3, and a flat part 13 for attaching a partition on the periphery of the vertical flange part, which is a curved unit panel for a corner integrally formed of synthetic resin such as FRP. Reference numeral 4 denotes a flat unit panel integrally formed of synthetic resin such as FRP, which is provided with a flange portion 3 extending perpendicularly to the end portion and directed outward at the peripheral edge of a flat rectangular pressure receiving surface 1.

In order to assemble the side wall 6 of the panel assembly type tank 15, as shown in FIGS. Parts 3 and 3 are provided in a semicircular shape through the water sealing material 2, and a flat unit panel is provided between the curved unit panels 8, 8, and 8 formed in a semicircle. 4 are connected via the water sealing material 2.

5 is the bottom wall of the panel assembly type tank 15 as shown in FIG.
A fan-shaped flat panel 16 having a center angle of 90 degrees of curvature and integrally formed of synthetic resin such as P and having a flange around the periphery is fixed to the lower surface of the side wall 6 via the water sealing material 2 with bolts and nuts 11, The flat panel 16.16.16.1
A flat unit panel 4 is placed between 6 and 6°C through a water sealing material 2.
It is connected.

7 is the ceiling wall of the panel assembly type tank 15 as shown in FIG.
A fan-shaped flat panel 1 having a central curvature angle of 90 degrees and integrally formed of synthetic resin such as FLP and having a flange portion around the periphery.
6 is attached to the upper surface of the side wall 6 through the water sealing material 2.
1, and between the plane panels 16, 16, and 16, a plane unit/mannel 4 is connected via a water sealing material 2.

In the above embodiment, the curved unit panel 8 and the planar unit panel 4 are stacked in one layer, but may be stacked in two, three, or four layers, respectively. In addition, two curved unit panels 8 are attached to the opposite corners with water sealing material 2.
Although the configuration is such that they are connected via the above-mentioned embodiment, the planar unit panel 4 may be inserted between the curved unit panels 8 and 8 and fastened with bolts and nuts 11. In addition, in the above embodiment, the curved unit panels 8, 8
．． Although the configuration is such that a flat unit panel 4 is connected between 8 and 8, the structure is not limited to the above embodiment, and the flat unit panel 4 may be removed to form a cylindrical panel assembly type tank. It is also possible to have a different configuration.

FIG. 3 is a perspective view showing an embodiment of the curved unit panel of the present invention. The curved unit panel 8 has a rectangular shape, and has the effect of moving perpendicularly to the longitudinal end of the pressure receiving surface 1, which is horizontally curved inward at a center angle of 90 degrees, toward the outside of the tank. It is.

FIG. 4, FIG. 5, and FIG. 6 are other embodiments of the present invention,
A concave portion 12 protruding inward is provided in the arcuate portion of the curved unit panel 8, and a flat portion 13 for attaching a partition is provided on the periphery of the vertical flange portion, allowing installation of piping, level gauges, partitions, etc. This makes it easier to install partitions that divide the tank.

In the embodiment of the present invention, the C1 curved unit panel 8 is formed with a central curvature angle of 90 degrees, so the corner part of the tank can be assembled with the minimum number of panels, improving work efficiency, and It has the advantage of being inexpensive. Further, since the curved unit panel is integrally formed of synthetic resin such as FRP, mass production by mechanical molding is possible, which has the advantage of being inexpensive.

(Effects of the Invention) Since the present invention has the above configuration, it has the following effects.

l) Because there are no corners in the tank, the flow of the stored liquid is good (no stagnation of liquid).

2) Since the tank has no corners, it is easy to clean and hygienic, and the assembly work is easy.
The horizontally curved shape keeps deflection to a minimum, eliminating the risk of liquid leakage, improving reliability, and reducing the risk of accidents even if high-temperature water, chemicals, etc. are stored inside. It disappears.

3) Conventionally, two planar unit panels were placed at orthogonal positions and connected via a reinforcing material and a water sealing material.
According to the present invention, since the structure can be made of one curved unit panel, the number of panels can be reduced and reinforcing materials can be omitted, and an assembly type tank can be manufactured at low cost.

4) Since the pressure-receiving surface of the curved unit panel used at the corner of the tank is curved in the horizontal direction, the wall thickness can be reduced, and material costs can be reduced.

5) The pressure-receiving surface of the curved unit panel used at the corner of the tank has vertical and flat flanges that connect to the substantially fan-shaped flat plates at both the top and bottom ends, so water sealing performance is maintained even when fastened to the bottom wall and ceiling wall. will improve.
