Description

[Detailed Description of the Invention] This invention relates to a tank used to store any liquid such as water.

Conventionally, the top wall of a tank such as this type of assembled panel tank has been supported by a number of supports interposed between the top wall and the bottom wall of the tank.

However, the structure in which the tank top wall is supported by a large number of columns has the following drawbacks.

That is, when manufacturing a tank, it is necessary to prepare a large number of supports, place them inside the tank, and then erect them separately, which makes the assembly work complicated and also increases costs. However, when cleaning the inside of the tank on a regular basis, the large number of pillars gets in the way and hinders the cleaning process.

This invention was made to eliminate the above-mentioned drawbacks.

This invention will be explained below according to a first embodiment shown in FIGS. 1 to 4.

As shown in FIGS. 1 and 2, a rectangular parallelepiped-shaped assembly type panel tank 1 is composed of a bottom wall 2, a top wall 3, and four side walls 4.

The bottom wall 2 and the top wall 3 each have a square shape with 16 square panels 5 arranged vertically and horizontally, and each panel 5 is in the shape of a truncated quadrangular pyramid. It is composed of a square main body 6 having a raised portion 6a in the center and hanging connecting edges 7 provided around the four peripheries, and the hanging connecting edges 7 of mutually adjacent panels 5 are connected to each other via a packing 8. By connecting them, the six panels 5 are integrated.

On the other hand, each of the four side walls 4 has a rectangular side surface with eight square panels 9 arranged side by side, four in the horizontal direction and two in the height direction, each of which has a truncated shape. A square main body 10 having a quadrangular pyramidal raised portion 10a;
The eight panels 9 are integrated by connecting the vertical connecting edges 11 of mutually adjacent panels 9 via the packing 8. has been done.

The side wall 4 is connected at its upper and lower edges to the hanging connecting edges 7 of the panels 5 located around the bottom wall 2 and the top wall 3 via packings 8, and at its left and right edges, corner members 1
2 and a gasket 8.

A column 13 is erected in the center of the tank 1, and the column 13 is composed of a lower member 14 housed within the tank 1 and an upper member 15 provided outside the tank 1.

The lower member 14 has upper and lower flanges 17.16 at its upper and lower ends.
The lower flange 16 is interposed at the lower surface of each central butting corner of the four central panels 5 forming a part of the bottom wall 2, and the lower flange 16 is located at the height of the hanging connecting edge 7 of the panel 5. A quarter disc-shaped spacer 1 having a height approximately equal to
8, respectively, by means such as bolts.

Note that the lower member 14 of the support column 13 may be attached to a tank base.

On the other hand, the upper flange 17 is abutted against quarter disc-shaped spacers 19 interposed on the lower surfaces of each of the central abutting corners of the four central panels 5 forming a part of the top wall 3. There is.

The upper member 15 also has upper and lower flanges 22 and 21 at the upper and lower ends, and the lower flange 21 is applied to the center of the top wall 3 and has a plurality of bolts passing through the panel 5, the spacer 19, and the flange 17. 23, are tightened and fixed together with a nut 24.

With this configuration, the upper and lower members 15 and 14 are integrated to form one support column 13.

Note that, like the spacer 18, the spacer 19 is made approximately equal in height to the hanging connecting edge 7 of the panel 5.

Four holes 25 are drilled in the upper flange 22 of the upper member 15, and a hook 27 at one end of a hanging tool 26 made of a wire rope, a chain, a metal rod, etc. is fitted into each of the holes 25. It is hung.

The hanging tool 26 is preferably provided with a turnbuckle mechanism in the middle of its length.

The hook 28 at the other end of the hanging fixture 26 is a stop for a locking fixture 29 installed between the first and second panels from the outside of the four panels 5 located diagonally on the top wall 3. The ring 30 is locked.

As clearly shown in FIGS. 3 and 4, the locking tool 29 has a plate-like main body 31 interposed between the abutted corners of the four panels 5 via a gasket if necessary, and It is fixed to the hanging connecting edge 7 by four sets of bolts 32° nuts 33.

Although it is desirable that the locking tools 29 be attached to the butting corners of the four panels 5, it is of course possible to attach them to other positions.

Next, a second embodiment shown in FIGS. 5 and 6 will be described.

Note that the same members as those shown in FIGS. 1 to 4 are designated by the same reference numerals as in those figures.

At the upper end of the lower member 14' of the support column 13', cuts 40 into which the hanging walls 7 of the panel 5 fit are formed at 90° intervals.

Therefore, in this embodiment, the spacer 19 is unnecessary, and the upper end flange 17 of the lower member 14' is made to directly contact the hexagonal portion of the main body of the panel 5.

A reinforcing member 41 is attached to the lower surface of the corner near the center of the panel 5 located at each corner of the top wall 3, and the reinforcing member 41 has a bolt insertion hole in the center as shown in FIG. 4
a right-angled isosceles triangular top wall 42 having an angle of 3;
A hanging wall 44 having a rectangular planar shape and having a port I/insertion hole 45 on the required side.
It is composed of.

The hanging wall 44 of the reinforcing member 41 is bolted to the hanging connecting edge 7 of the panel 5 using bolt insertion holes 45.

A bolt 47 with a retaining ring 46 is fitted into a through hole 48 and a bolt insertion hole 43 drilled in the panel 5, and is inserted into a nut 4.
It is attached to the panel 5 by screwing 9.

The hook 28 of the hanging tool 26 is fixed to the retaining ring 46.

7 to 9 show other embodiments of the reinforcing member.

Bolt insertion holes 51 and 52 on required sides are bored in the base wall of the reinforcing member 50, which has an inverted cross section as shown in FIG.

The reinforcing member 53 shown in FIG. 8 is composed of a main body 55 having a rectangular planar shape having a bolt insertion hole 54, and a top wall 57 provided in a part of the main body 55 and having a bolt insertion hole 56.

The reinforcing member 50 is applied to the hanging wall, and the reinforcing member 53 is used to apply the main body 55 to the hanging wall 7 of the panel 5.

The reinforcing member 58 shown in FIG. 9 has a cross-shaped groove 59 into which each corner of the hanging connecting edge 7 of the four panels 5 arranged in a plane with their corners abutted is fitted. The groove 59 also has four top walls 61 connected to the side walls 60, each of which has a bolt insertion hole 62. A retaining ring bolt or an ordinary bolt is inserted through a hole drilled in the panel 5.

In addition, in this invention, the position of the struts is arbitrary, and the number of struts and hanging tools is also arbitrarily determined depending on the size of the tank.

When two or more struts are erected, it is desirable that the struts be placed in positions that are line-symmetric or rotationally symmetrical when the top wall of the tank is viewed from above.

In addition, in addition to attaching the upper end of the required side hanging tool to the upper end of the upper member of the strut, it is also possible to attach
Of course, it is also possible to attach the upper ends of an appropriate number of hanging tools.

In this case, the hanging tool that suspends the top wall part near the pillar is
It is desirable that the hanging device be attached to a low position in the middle of the upper member of the support column, and that the hanging holder for suspending the top wall portion farther from the support be attached to a higher position in the middle of the upper member of the support support.

In this way, even if you have a large-capacity tank with a large total area of the top wall, by attaching multiple suspension holders of different heights to one or several columns, you can easily reach important points on the top wall. Since it can be suspended like a coaxial overlapping cone, the work efficiency is further improved compared to the conventional method, and it is also aesthetically superior.

Also, as a support, it is also possible to use a plurality of units of a specified length that have a fitting protrusion on one end and a fitting recess on the other end and are connected and fixed to each other to obtain an arbitrary length. It is possible.

Alternatively, a single support may be used to penetrate the top wall of the tank.

According to this invention, a support is erected at a desired position of the tank with its lower end positioned on the bottom wall or base of the tank and its upper end positioned above the top wall of the tank. Required parts of the tank top wall are suspended by hanging tools such as wire ropes and metal rods that are fixed above the wall, and do not require a large number of supports as in the past. This makes construction of the tank easier, and there are advantages in that many supports do not get in the way when cleaning the inside of the tank, improving cleaning work efficiency.

Furthermore, if the lower end of the column is firmly attached to the base, the column acts like a mainstay, and the earthquake resistance of the entire tank can be strengthened.
