Description

[Detailed explanation of the idea] This invention relates to an assembly type lid for a tank.

When building the lid of a large container such as a tank in one piece from the beginning, it must be transported to the location where the tank will be installed, or
It is often inconvenient to install it above the tank.

Also, it is not convenient to make the lid of the tank with a plate with a flat top because rainwater collects on the lid.

Therefore, in order to prevent these drawbacks, the tank lid is made by dividing it into right-angled quadrilateral-shaped unit plates, which makes transportation and installation easier. It was proposed that rainwater would flow down through the slopes of a truncated pyramid (Jikko Kouko 51-4).
No. 4974).

However, the above-mentioned lid was not yet complete.

The reason for this is that in the above-mentioned lid, the four sides of the unit plates are on the same horizontal plane, so the sides that touch each other between adjacent unit plates are located in the horizontal direction, and the accumulation on these sides is This is because there was a drawback that the water could not easily drain away.

This invention was made to improve the above-mentioned drawbacks, and by making the sides where adjacent unit plates meet each other curved lines that protrude upward, water on the sides can easily flow off. This is how it was done.

In other words, this idea places a right angled quadrilateral almost horizontally,
At least one side of the two opposing sides is bent to form a curved line that projects upward, and a curved surface of medium height is formed between the bent side and the remaining side, and the curved surface projects downward along the bent side. This is an assembly-type lid for a tank, in which a plurality of unit plates are arranged with their bent sides abutting each other, and the joint edges are fixed together.

The assembled tank lid according to this invention will be explained as follows based on the drawings.

FIGS. 1 to 3 are partially cutaway perspective views showing an example of an assembly type lid for a tank according to the present invention.

FIG. 4 is a sectional view showing a stacked state of unit plates forming the lid shown in FIG. 3. FIG.

5 and 6 are partially cutaway perspective views showing another example of the assembled lid for a tank according to this invention.

In FIG. 1, a right angled quadrilateral ABCD is placed approximately horizontally.

At least one side (two sides in the figure) of the two opposing sides AB and CD is bent to form a bent line projecting upward.

A medium-height curved surface 1 is formed between the curved sides AB, CD and the remaining sides BC, DA.

Joint edge 2 protruding downward along bent sides AB and CD
is attached.

In this way, the unit plate p is made.

In the same way, the same type of unit plate pi, I)2 is made,
These unit plates p, p1, I)2 are arranged with their bent sides abutting each other.

That is, side CD of unit plate p and side A1B1 of unit plate p1
side C1D1 of unit plate p1 and unit plate p
2 sides A2 and B2 are butted against each other.

The joining edges 2 attached to the bent sides are fixed to each other.

What is constructed in this way is an assembly type lid for a tank according to this invention.

In the above lid, the right quadrilateral ABCD may be a square or a rectangle.

When the right-angled quadrilateral ABCD is a rectangle, it is desirable that the bent sides be the long sides.

A curved line having a shape of a bent side includes a curved line and a broken line.

The curved line includes an arcuate line, and the broken line includes a broken line having one or more folds in the middle.

In the curved surface 1, middle height means that the height increases from the edge toward the center.

In addition to the slope, the bent surface 1 may include a horizontal surface (for example, the top surface of a four-sided or octagonal truncated pyramid) and a vertical surface (for example, a square cylindrical surface).

The joining edge 2 attached to the bent side is the original right quadrilateral AB
It is preferable to stand upright with respect to the CD.

In addition, as shown in the figure, even along the remaining sides BC and DA,
A depending edge 3 similar to the joining edge 2 can be provided.

It is desirable that the joint edges 2 are fixed to each other using bolts 4.

The above unit plate p is suitably made of metal (for example, iron, stainless steel, etc.) or reinforced synthetic resin (for example, glass fiber reinforced polyester resin).

Further, a layer made of a heat insulating material can be included in the plate 1 on the bent surface of the unit plate.

Note that the number of unit plates constituting one lid may be any number as long as it is two or more.

Figure 1 shows one of the basic embodiments of this invention.
It is one.

This idea also includes some modifications.

For example, in Figure 2, the assembled tank lid of this invention is
It is assembled from unit plates q, q, and q2.

The unit plate q is the same as the unit plate p shown in FIG. 1, except that CD is the only bent side, a hanging edge 3 is attached to the remaining three sides, and a horizontal edge 5 is attached to the tip of the hanging edge 3.

The unit plate q1 is the unit plate p shown in FIG. 1 with a horizontal edge 5 added to the end of the hanging edge 3.

Unit plate q2 is of the same type as unit plate q. In Figure 2, unit plates q and q2 are placed on both sides with unit plate q1 in between.
are lined up, their respective bent sides are brought into contact with each other, and the joining edge 2 is fixed, thereby constructing the lid.

In this lid, the horizontal edge 5 abuts the upper end of the side wall,
Used to fix the side wall and lid.

Note that the tip of the horizontal edge 5 may be bent downward.

In Figure 3, the assembly type lid for the tank of this invention is shown in the unit plate r.
, r1 and r2.

These unit plates are of the same type, and in the unit plate p shown in FIG. corresponds to that given.

Note that the lower end of the joining edge 2 is a bent line parallel to the upper end.

These unit plates are connected in the same way as in FIG.
He is holding the lid.

Since the unit plates r described above can be stacked as shown in FIG. 4, they have the advantage that they do not take up a lot of space for storage and that they are less likely to collapse when stacked.

In Fig. 5, the assembled tank lid of this invention is shown in the unit plate S.
and S1.

These landing plates are of the same type, and the bent surface 1 of the unit plate p shown in FIG. corresponds to

A cylindrical protruding surface 15 may be further provided on the bent surface 14.

This cylindrical protruding surface 15 is used, for example, to provide a manhole 6.

Note that a protrusion 16 may be provided on the edge surface 11.

This protrusion 16 serves to support the lower end of the hanging edge 3 of the upper unit plate when the unit plates are stacked.

These unit plates are connected in the same way as in FIG.
He is holding the lid.

In Fig. 6, the assembled tank lid of this invention is shown in the unit plate 1.
, 11 and t2.

These unit plates are of the same type, and in the unit plate p shown in FIG.
7.

A cylindrical protruding surface 15 may be further provided on the curved surface 17.

This cylindrical projecting surface 15 is used to provide a manhole 6, as in the case of FIG.

These unit plates are connected in the same way as in FIG.
It forms a lid.

The assembled lid for a tank of this invention is made by placing a right-angled quadrilateral almost horizontally, bending at least one of its two opposing sides, and forming a bent surface between the bent side and the remaining side. Since the unit plate has a curved surface with a middle height, water on the curved surface easily flows down toward the four sides.

In addition, the bent sides are curved lines that protrude upward, and when connecting the unit plates, the bent sides are brought into contact with each other, so water that flows down onto the sides that are brought into contact with each other between adjacent unit plates is However, it easily flows to the edge of the lid.

Therefore, the assembled tank lid of this invention has the advantage that water does not accumulate on the top surface.
