Description

[Detailed Description of the Invention] This invention relates to a unit plate for assembling a container, particularly a unit plate that is easy to assemble the bottom of a container.

It has already been done to create large containers such as tanks by combining unit plates.

The unit board for this purpose was a right-angled rectangular board whose peripheral edge was bent in the same direction to form a connection edge there.

As connection edges, there are known oblique connection edges that stand up from the substrate at an angle of 135° and upright connection edges that stand up at right angles.

Slanted connecting edges are used to form right-angled corners, such as bottom-to-side wall connections or corner portions of side walls.

On the other hand, the upright connecting edge is used as a connecting edge for coplanar extension of the unit plates.

However, the upright connecting edge can also be used to form a right-angled heel by connecting via an angle piece.

Unit plates for forming the bottom of a container require different consideration than unit plates for forming the side walls of the container.

When cleaning the inside of the container, it is necessary to improve drainage, and for this purpose it is necessary to provide some kind of water gradient at the bottom.

For this purpose, it is necessary to tilt the base plate itself of the unit plate that forms the bottom.

In this case, conventional unit board structures have been designed with the board as the center and the connection edges standing upright from it, but in this case, the upright connection edges also slope as the board inclines, causing problems.

Therefore, instead of using the substrate as a reference, it became necessary to use a ground plane connecting the ends of the connecting edges as a reference and to make the connecting edges stand upright with respect to this.

Further, the unit plates constituting the bottom are arranged on the ground plane with the connecting edges facing downward.

To make a connection in this state, a worker must crawl under the unit board and make the connection.

This requires special ingenuity.

As a means for this purpose, a high pedestal is provided, a unit plate is laid on the pedestal, and a worker enters between or inside the pedestals to perform work.

However, since the movement of the operator is still restricted by the frame, it is not easy to connect the unit boards.

This is because concrete walls were often used as frames for economical reasons, but with concrete walls, workers were located on both sides of the concrete wall, and each of them used signals to connect the connecting edges of the concrete walls. , even though it was necessary to tighten bolts, the workers were blocked by a concrete wall and could not even give a satisfactory signal.

The inventor of this invention intended to facilitate the assembly work in the above-mentioned cases.

As a result, I came up with the idea of drilling a small hole at the tip of the connecting edge of the unit plate, that is, at the tip of the seal formed by the packing and bolting.

Drilling holes in the connecting edge has not yet been done, since this generally reduces the strength of the connecting edge.

However, it was confirmed that as long as the hole is located at the tip of the connecting edge and the size of the hole is not very large, it does not significantly reduce the strength.

In addition, it was confirmed that when the shape of the hole is long and extends parallel to the ground plane, the strength is not significantly reduced and it is convenient for giving signals.

This idea was made based on such confirmation.

This idea is to provide a connection edge by bending the peripheral edge of the board in the same direction, and to make an upright connection edge by positioning the tip of the connection edge perpendicular to the ground plane connecting the tips of the connection edge. In a unit plate with a connecting bolt hole provided in the unit plate, a part of the upright connecting edge at the tip of the bolt hole is cut out to provide a through hole penetrating the connecting edge in the thickness direction, and the cross-sectional shape of the through hole is aligned with the ground plane. This invention relates to a unit plate for container assembly, which has a shape that extends long along the .

This invention will be explained as follows based on the drawings.

1 to 7 are perspective views of unit plates according to this invention, some of which are cut away.

8 to 10 are partially cutaway perspective views of a container using unit plates according to this invention.

The unit plate shown in FIG. 1 has a structure as described below.

A board 1 consisting of a flat plate in the form of a right-angled quadrilateral is recurved on the same side on all four sides to provide inclined connection edges 2 to 5 that form an angle of 135° with respect to the board 1, and furthermore, the inclined connection edges 2 to 5 are provided at an angle of 135° with respect to the board 1. Upright connecting edges 6 to 9 are provided that stand up at right angles to each other, and a through hole 10 is provided at the tip of each of the upright connecting edges 9 to 9.

On the four circumferences of the unit plate, bolt holes 11 are provided on either the inclined connecting edge or the upright connecting edge.

Bolt holes 11 are provided on the inclined connection edge when unit plates are connected at right angles, and bolt holes are provided on the upright connection edge when unit plates are connected on one plane.

A packing is placed in contact with the part where the bolt hole is provided,
The connecting edge of another similar component plate rests on top of this and is bolted to form an airtight connection, a so-called seal.

The inclined connecting edges 2 to 5 in FIG. 1 all have equal widths, and the upright connecting edges 6 to 9 also have equal widths.

As a result, the substrate 1 is parallel to the ground plane that connects the tips of the upright connecting edges 6 to 10.

The through holes 10 are provided above the upright connecting edges 6 to 9, but are located more distally than the bolt holes 11, avoiding the so-called seals.

Further, the through hole 10 extends long along the ground plane, and has a rectangular shape with rounded edges.

The long side of the rectangle is at least twice as long as the short side, and the short side is at least twice the diameter of the bolt hole.

The fact that the through hole 10 is located closer to the tip than the bolt hole 11 means that the periphery of the through hole 10 is located at a distance greater than the diameter of the bolt hole from a line connecting the centers of the bolt holes. ing.

The through hole 10 contacts the tips of the upright connecting edges 6 to 9,
It may be connected to the tip.

The through holes 10 are also provided avoiding the ridges formed by the upright connecting edges or 9 adjacent to each other, i.e. avoiding the corners of the right quadrilateral.

It is desirable that the through holes 10 be divided into a plurality of holes and provided in a centrally symmetrical manner even on one upright connecting edge.

The through hole 10 has a shape that extends long in the direction of the ground plane,
It is desirable that it be so-called horizontally elongated, and at the same time be larger than that.

It is desirable that the size is at least twice the diameter of the bolt hole in the height direction, that is, the short side direction, and the length thereof is 5 mm or more.

Further, it is desirable that the size thereof is 200 square mm or more in terms of area.

In FIG. 2, the periphery of a right-angled substrate 1 is provided with upright connecting edges or 9 of equal width, without inclined connecting edges.

Bolt holes 11 will therefore be provided on every upright connecting edge.

The through hole 10 is located closer to the tip than the bolt hole 11, but does not connect with the tips of the upright connecting edges 6 to 9, and has an elliptical cross section extending along the ground plane.

Also, in the direction parallel to the ground plane, the through holes 10 are located in symmetrical positions on one upright connecting edge.

In the unit plate shown in FIG. 2, a pyramid-shaped protuberance 12 is attached to the center of the substrate 1.

This protrusion serves to improve water drainage on the substrate 1.

The unit board shown in FIG. 3 has upright connecting edges 6, 7 and 9 formed around three sides of the substrate 1, and no upright connecting edge is provided on the remaining side.

The substrate 1 is inclined with respect to a ground plane that connects the ends of these upright connecting edges, so that the upright connecting edges 6 are low.

The substrate 1 is also bent along the side where the upright connecting edge is not provided, ie along the line 13, so that it is provided with a horizontal portion 14.

The horizontal portion 14 is parallel to the ground plane.

In this connection, the upright connecting edges 7 and 9 appear trapezoidal when viewed roughly, but on closer inspection they are slightly bent at the folding line 13, so that they have a pentagonal shape.

In the unit plate of FIG. 3, bolt holes 11 are provided on the upright connecting edges 6, 7 and 9.

The bolt holes 11 are arranged adjacent to the substrate 1 on the upright connecting edge 9 in a row.

The through hole 10 is provided at the tip of such a bolt hole 11, but when viewed in a direction parallel to the ground plane, the through hole 10 is provided biased toward the side near the horizontal portion 14. There is.

In the figure, a bolt hole 15 is provided closer to the tip than the through hole 10, but this is different from the bolt hole 11 in the seal portion and is used for a different purpose.

Therefore, the through hole 10 is always located closer to the tip than the bolt hole 11.

Note that bolt holes 11 are also provided in the horizontal portion 14.

The unit plate shown in FIG. 4 has a structure in which upright connecting edges 6 to 9 are attached to the four circumferences of the substrate 1.

Among these upright connecting edges, connecting edges 7 and 8 have a right-angled quadrilateral shape with equal height, while connecting edges 6 and 9 have a trapezoidal shape with the front side lowered.

As a result, the substrate 1 is bent along the diagonal line 16, and both halves separated by the diagonal line 16 have the diagonal line 16 lowered.

Further, the diagonal line 16 itself is also inclined, and the front side is lower.

However, each of the upright connecting edges 6 to 9 is perpendicular to the ground plane that connects the tips of the connecting edges.

A bolt hole 11 is provided on each upright connecting edge 6 to 9 in FIG.

On the upright connecting edges 6 and 9, a through hole 10 is provided along the tip of the bolt hole 11.

The through hole 10 extends in a direction parallel to the ground plane over almost the entire connecting edge except for the corner portion of each connecting edge.

The unit board shown in FIG.
7 is formed, at the end of which upright connecting edges 6 to 9 are attached.

The face scraping portion 17 is inclined with respect to the upright connecting edges 6 to 9, and the inclination angle is 135° with respect to the upright connecting edge.
It differs from an inclined connecting edge in that it does not form a fixed angle.

Among the upright connecting edges, the connecting edge 6 and the connecting edge opposite thereto both have a right-angled quadrilateral shape, but the connecting edges 7 and 9
It is originally a trapezoid.

As a result, the substrate 1 is inclined such that the upright connecting edge 6 is lower with respect to the ground plane.

Bolt holes 11 are provided on each of the connecting edges 6 to 9.

A through hole 10 is attached to each of the connecting edges 7 and 9 at the tip of the bolt hole 11.

In the direction parallel to the ground plane, the through-hole 10 has an upright connecting edge 7
and almost the entire range extending to 9.

The through hole 10 has an elongated triangular shape in the direction of the ground plane, and has an extremely small length in the height direction.

The unit board shown in FIG. 6 is different from the one shown in FIG. 5 in that it does not have a face-shaving section 17, but instead has a hexagonal pyramid-shaped protuberance 18 in the center of the substrate 1. .

The upright connecting edge 6 and the opposing upright connecting edge both have a right-angled quadrilateral shape, and the substrate 1 is inclined with respect to the ground plane so that the upright connecting edge 6 is lower at the waist. It is the same as the one in Figure 5.

On the upright connecting edges 6 to 9 of FIG.
is attached.

A through hole 10 is provided in the upright connecting edge 9 and the opposite upright connecting edge.

The through hole 10 has an elongated rectangular shape with rounded edges, and extends over almost the entire length of the tip of the connecting edge 9 in the direction parallel to the ground plane, leaving only both sides of the connecting edge 9 intact.

The unit plate shown in FIG. 7 is similar to that shown in FIG.

The difference is that in the one shown in FIG. 7, an upright connecting edge 8 is attached to the tip of the horizontal portion 14, therefore, a bolt hole 11 is not provided in the horizontal portion 14, and the board 1 is a composite one. The two points are that it has a plate structure, and that the shape of the through hole 10 is a triangle that extends long on one side.

The unit plate according to this invention has a through hole at the tip of the upright connecting edge, so when a large number of unit plates are installed to assemble the bottom of a container, the assembled bottom can be seen through the through hole, and It provides a variety of conveniences, such as being able to signal to the other side that is blocked by the frame, and furthermore, allowing connections to be exchanged through the through-holes, and in some cases allowing pipes to be passed through.

In addition, this through hole is located at the tip of the bolt hole of the upright connection edge, and its cross-sectional shape is such that it extends long along the ground plane, so it does not reduce the strength of the unit plate. It brings benefits.

FIG. 8 is a partially cutaway perspective view of a container in which the unit plate shown in FIG. 1 is used.

In FIG. 8, a concrete pedestal B is erected on the ground A in the form of a standing wall extending in only one direction.

An H-shaped steel C is placed on the top surface of the frame B, and the top surface of the shaped steel C is positioned horizontally to form a ground plane.

On this ground plane, the unit boards, E, etc. according to this invention are laid.

At this time, the upright connection edge provided with the through hole 10 is placed on the section steel C.

Then, the through holes 10 overlap between the unit board and E, allowing workers separated by the frame B to communicate with each other through the through holes 10, facilitating assembly.

Moreover, tools can be transferred through the through hole 10, and sometimes piping can be installed, which is convenient.

FIG. 9 shows the bottom of a container assembled by placing the unit plates as shown in FIG. 2 directly on a concrete pedestal B.

However, in FIG. 9, the protuberance 12 provided on the substrate 1 of the unit board is omitted, and the through holes 10 are not limited to those shown in FIG. 2, but those shown in FIGS. The various types shown in Figure 7 are shown being used together.

In any case, a gap is formed between the upright connecting edges that are abutted against each other on the pedestal by overlapping the through holes 10, which is convenient for the work.

Note that FIG. 9 shows that there may be a step at the joint of the substrates between adjacent unit boards.

In other words, this shows that there is no problem even if there is a difference in level between the substrates as long as the peripheral edge of the bottom is high.

FIG. 10 shows a unit plate in which a side wall portion 19 and a horizontal connecting edge 20 around the side wall portion 19 are integrally attached to the unit plate shown in FIG. 4.

In this unit plate, an additional piece 21 is provided at the bottom of the upright connecting edge 6.
is added, thereby increasing the gap between the top surface of the concrete pedestal B and the upright connecting edge 9 of the unit plate.
