Description

[Detailed explanation of the idea] This invention relates to a tank with a lid.

It is convenient to make the lid of a large container such as a tank by dividing it into unit plates, rather than taking them all together from the beginning, and then transporting the unit plates to the installation site and assembling them together there.

Based on this idea, we developed a unit board (Utility Model No. 50-642) in which the periphery of a right-angled board is bent to the same side and an upright joint edge is provided that stands upright at an angle of approximately 90 degrees to the board.
No. 13) was used.

The lid of a tank or the like needs to be able to withstand such loads because people may stand on it or snow may accumulate on it.

To do this, the lid must be reinforced in some way, but when the above-mentioned unit plates are combined to form a lid,
It has been found convenient to support the abutting edges of the four unit plates from below by supports.

It is already known to run struts between the side walls in order to prevent deflection between the side walls when unit plates with upright joint edges are connected to form an aquarium.

In that case, in order to stably fix the column where the four unit plates meet at one point, it is recommended to attach a fixing device to the end of the column and provide a cross-shaped groove at the tip of the fixing device. Are known.

It is described in Japanese Utility Model Application Publication No. 50-66439.

However, Japanese Utility Model Application Publication No. 50-66439 only describes a case in which a support is fixed horizontally to an upright side wall, and does not describe supporting the lid from below by a support.

Furthermore, since this publication is based on the assumption that it will be fixed to the side wall, it states that a fixing device with a cross-shaped groove should be made separately from the column and attached to the column because of the structure of the side wall.

However, when the lid is supported by a post, it has been found to be more convenient to provide a cross-shaped groove directly at the end of the post.

This invention was made based on such knowledge.

In other words, this device arranges unit plates in the shape of a right angled quadrilateral with upright joint edges, turns the upright joint edges of the unit plates downward, and connects the corners of at least four unit plates to each other at one point. The point where they meet is supported from below by a support, and a cross-shaped groove is provided on the upper end surface of the support, and the width of the groove is approximately equal to twice the thickness of the upright joint edge of the unit plate. C,
This is a tank with a lid, in which the upright joint edge is fitted into the groove, a support is erected, and the lower end of the support is fixed to the bottom of the tank.

The tank with a lid of this invention will be explained as follows based on the drawings.

FIG. 1 is a partially cutaway exploded perspective view showing an example of a combination of a lid and a support in the lidded bunk of this invention.

FIG. 2 is an assembled view of the device shown in FIG. 1.

FIG. 3 is a sectional view showing an example of a tank with a lid of this invention.

FIG. 4 is a partially cutaway perspective view showing an example of a method for fixing the lower end of the support column in the lidded tank of this invention.

FIG. 5 is a partially cutaway perspective view showing another example of the lower end of the column.

In FIG. 1, the lid according to this invention has four or more unit plates 1 arranged side by side and supported by supports 2.

The unit plate 1 is constructed by providing upright joining edges 12 around the four peripheries of a right-angled rectangular substrate 11.

The center portion of the substrate 11 may bulge upward.

The unit plates 1 are integrally coupled to form a lid with the upright joining edges 12 facing downward and the upright joining edges 12 abutting each other.

The connection is made through bolts between the upright joining edges 12.

As a result, in the lid, the corners of the four unit plates 1 come into contact with each other at one point X.

This state can also be seen as a shape in which the upright joining edges 12 of the four unit plates 1 intersect at the above-mentioned point X in a cross shape.

The point X where they touch is supported by a support 2 from below.

The support column 2 is a long body with a cross-shaped orthogonal groove 21 provided at the upper end thereof.

The width of the groove 21 is approximately equal to twice the thickness of the upright joining edge 12 of the unit plate 1, but may be slightly wider than this.

The depth of the groove 21 varies depending on the height of the upright joint edge 12 of the unit plate 1, but is preferably about 20 mm to 1QQmm.

Although it is convenient to use a hollow body as the column 2 as shown in the figure, it may also be a solid body.

As the material of the support column 2, metal, polyvinyl chloride, fiber-reinforced thermosetting resin, or the like is used.

As shown in FIG. 2, the cross-shaped upright joint edges 12 of the unit plate 1 are fitted into the grooves 21 of the support column 2 described above.

In this way, the lid made of the unit plate 1 is reliably and firmly connected to the column 2.

The lower end of the column 2 is brought into contact with the bottom 3 of the tank, as shown in FIG. 3, and fixed, for example, with adhesive.

As shown in the diagram, there is a post 2 that is slightly taller in the center of the tank.
The height of the support column 2 may be reduced as it approaches the periphery of the tank.

If you do the above, the tank lid will have a slope, so
Improved drainage of rainwater, etc.

Incidentally, when the bottom of the tank is composed of unit plates, it is convenient to configure it as shown in FIG. 4.

The unit plate 4 shown in FIG. 4 has a structure in which inclined joining edges 42 are provided around the four peripheries of a right-angled substrate 41, and an upright joining edge 43 is provided beyond the inclined joining edges 42.

A fixing device 5 is attached to the lower end of the column 2, and the fixing device 5 is provided with a notch 51 on its lower surface that corresponds to the inclined joining edge 42.

Such a fixture 5 is explained in detail in Japanese Utility Model Application Publication No. 50-66439, so the details will be based on that explanation.

In this case, in order to abut the support column 2 on the bottom of the tank, it is convenient to fit the lower surface of the fixture 5 into the corners where the four unit plates 4 touch each other and fix the support column 2 to the bottom of the tank.

Also, instead of using the fixing tool 5, at the lower end of the support column 2,
A notch 22 similar to the notch 51 may be provided.

These notches 51 or 22 are convenient because when they are brought into contact with the inclined joint edge 4 of the unit plate 4, the lower end of the column 2 can be fixed easily and reliably.

The tank with a lid of this invention has a strong lid because it is supported by a support that stands up from the bottom.

Generally, when four unit plates are joined together in a plane with their edges butt-to-edge, the abutting part located in the center is weak against the load, but in this invention, Since the corners are supported from below by pillars, the reinforcing effect is great and the lid is therefore strong.

Therefore, even if someone steps on the lid or snow accumulates on it, the lid is less likely to break.

Further, the lid is easily fixed because the upright joining edges intersecting each other in a cross shape fit into the cross-shaped groove provided directly on the upper end surface of the support column.

Moreover, since the width of the groove is approximately equal to twice the thickness of the upright joint edge, there is little movement of the fitting portion, and therefore the lid can be firmly attached for a long period of time.

Furthermore, since both the unit plate and the support are simple in structure, this tank with a lid is easy to manufacture and inexpensive.

The lidded tank of this invention has the above-mentioned advantages.
