Description

[Detailed Description of the Invention] This invention relates to a joint used when attaching a strut inside a tank.

The lids of large containers such as tanks can be subject to loads due to people riding on them or snow accumulating on them, so large lids need to be supported at important points with supports. .

This support supports the space between the bottom and the lid, so
As the height of the tank increases, the length of the support also increases.

However, the work of transporting and installing a long support in a tank is extremely complicated.

Therefore, the inventor came up with the idea of dividing the column into unit columns of a certain length, transporting the unit columns to the tank installation location, and assembling them into a long column using joints there.

On the other hand, in a tank that stores liquid, when the liquid level in the tank rises, the side wall deforms so as to bulge outward, and when the liquid level falls, the side wall deforms so as to dent further inward after passing through its original position.

Therefore, in order to prevent the above deformation, it has become common practice to support the opposing side walls of the tank with long stays.

However, when a long stay was passed between opposing side walls of a tank, the stay flexed under its own weight, and as a result, the side wall could move by an amount corresponding to the flexure.

In order to prevent the above-mentioned drawbacks, the inventor considered the idea of erecting a post close to the stay, attaching a protruding piece for supporting the stay to the post, and supporting the stay with the protruding piece.

In this way, the joint and the protruding piece were attached to the column.

The inventor further considered making one article serve as two members, the joint and the protruding piece.

As a joint having a protruding piece, a metal fitting used for assembling a desk, a chair, etc. is described in Japanese Utility Model Publication No. 47-28004.

The metal fitting described in this publication has a cross-shaped projecting piece for fitting a horizontal pipe on the side surface of a columnar main body.

However, the protruding piece of this metal fitting was not suitable for supporting a long stay extending across the opposite side wall of the tank.

To be more specific, the stay vibrates with a large amplitude in the center, like the strings of a stringed instrument, due to wall vibrations caused by water being supplied into the tank, but the protruding piece of the metal fitting mentioned above was only used to hold the stay. Therefore, it was decided to allow the stay to vibrate freely.

If the stay vibrated freely, the fixing parts at both ends of the stay would loosen or be destroyed, which was inconvenient.

The protruding piece of the metal fitting mentioned above has a shallow groove formed on the top surface of the root, but this shallow groove could not prevent the stay from freely vibrating.

The inventor noticed that vibration of the stay can be suppressed by bending the groove provided in the protruding piece in the depth direction.

I realized that if I formed a groove wall at the bent end to receive and stop the stay, it would be possible to support it stably.

This idea was born based on such knowledge.

That is, this invention is a joint in which a protruding piece is attached to the side surface of a columnar body, and a groove is provided in the protruding piece to penetrate linearly from one side to the opposite side, and the groove is bent in the depth direction,
This is a tank support joint in which a groove wall extending perpendicularly to the axis of the columnar body is formed in the bent part.

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

FIG. 1 is a partially cutaway perspective view showing an example of a column joint according to this invention.

FIG. 2 is a perspective view showing another example of the strut joint according to this invention.

FIG. 3 is a sectional view showing still another example of the strut joint according to the invention.

FIG. 4 is a cross-sectional view showing the state of use of the column joint according to this invention.

In FIG. 1, two protruding pieces 2 are provided on the side surface of a columnar body 1.

The top surface of the protruding piece 2 is provided with a groove 21 that extends linearly from one side to the opposite side.

The groove 21 is bent in an L-shape halfway in the depth direction.

A groove wall 2 extending perpendicularly to the axis of the columnar body 1 is provided at the bent portion.
2 is formed.

This structure is the tank support joint A according to this invention.

In the above-described column joint A, the columnar body 1 may be hollow or solid, or may be a cylinder or a polygonal column such as a hexagonal column or an octagonal column.

In the illustrated example, the columnar body 1 includes a through hole 11 along the axis.
A cylinder with .

This through-hole 11 is used for inserting and connecting the column-forming unit column Px from the upper end and the lower end, as shown by the chain line in the figure.

In this case, it is desirable to provide wart-shaped or ring-shaped protrusions 12 at positions approximately equidistant from both the upper and lower ends of the through-hole 11 .

Instead of providing the protrusion 12, the hole surface may be provided with an inward taper or may be provided with a thread.

In addition, when the above-mentioned joint A is used to connect a cylindrical unit column having a large diameter, the end of the unit column can be placed over the outside of the columnar body 1.

In this case, a groove corresponding to the protruding piece 2 may be provided at the lower end of the unit column, and the protruding piece 2 may be inserted into the groove.

The number of protruding pieces 2 is not limited to the two illustrated, but may be one or three.
It can be more than one.

The protruding piece 2 may have a shape like a cutout of a plate, or may have a shape like a bent rod.

It is desirable that the protruding pieces 2 protrude in a radial direction with respect to the axis of the columnar body 1.

When the projecting piece 2 is plate-shaped, it is desirable that the plate surface be oriented perpendicularly or parallel to the axis of the columnar body 1.

In the illustrated example, the protruding piece 2 is plate-shaped, and the plate surface is oriented parallel to the axis of the columnar body 1.

The groove 21 of the protruding piece 2 accommodates the stay Q, and the groove surface 22 receives and supports the stay Q, as shown by the chain line.

It is desirable that the above-mentioned strut joint A is made of metal such as stainless steel, or synthetic resin such as vinyl chloride resin, and is made of one piece.

What is shown in FIG. 1 is a typical example of a tank support joint according to this invention.

This idea also includes the following as another example.

The prop joint B according to this invention shown in FIG. 2 has a hollow columnar body 1 and four protruding pieces 2.

A groove 21 bent in an L-shape in the depth direction is provided on the top surface of each of the protruding pieces 2, and a groove is also provided symmetrically on the bottom surface.

As a result, this prop joint B has the advantage that its shape does not change even if it is turned upside down.

Further, a total of two stays can be held in the upper and lower grooves.

Furthermore, since the four protruding pieces protrude perpendicularly to each other, it is possible to simultaneously support the stays stretched across the tank.

In addition, in this column joint B, both the upper and lower ends of the columnar body 1 are
Since it protrudes upward and downward from the projecting piece 2, even when the unit column Px is placed over the outside of the columnar body 1, there is no need to provide a groove at the end of the unit column Px as shown.

In the tank support joint C according to this invention shown in FIG. 3, the outer peripheral surface of the columnar body 1 is provided with a tapered shape.

This taper has the effect of making the connection stronger when the unit column Px is connected by covering the outside of the columnar body 1.

Further, the hole surface of the through hole 11 provided in the columnar body 1 is provided with an inward taper.

This taper has the effect of making the connection stronger when the unit column Px is inserted into the hole 11 and connected.

The tank support joint according to this invention is used, for example, as follows.

In FIG. 4, a tank is installed on a concrete frame R.

The bottom, side walls and lid of the tank are assembled from unit plates 81T and U, respectively.

These unit plates all have upright joining edges 4 around the four peripheries of a right-angled rectangular substrate 3, and among them, the unit plate S
In and U, the substrate 3 bulges out to the side opposite to the side where the upright joint edge 4 is attached, and in the unit plate T, it is depressed toward the side where the upright joint edge 4 is attached.

In place of the unit plate described above, a unit plate without irregularities on the substrate can be used.

Also, between the substrate and the upright bonding edge, there is a
A unit plate may be provided with a beveled joint edge that is tilted at an angle of .degree.

Note that the tank may be made in one piece instead of being assembled.

A support P is erected inside the tank.

The strut P is constructed by longitudinally connecting a plurality of cylindrical unit columns PI and P2 via the strut joint A of this invention.
It is configured.

The connection is made by inserting the upper end of the unit column P1 and the lower end of the unit column P2 into the hole 11 of the column joint A, respectively.

An adhesive may be applied to the insertion surface during insertion.

The lower end of the unit column P1 is in contact with the substrate of the unit plate S constituting the bottom.

The upper end of the unit column P2 is inserted from below into the hole 11 of another column joint A, and a fixture (2) is inserted above the hole 11.

The fixture (2) has a groove on its upper surface, into which the upright joining edge 4 of the unit plate U forming the lid is inserted.

In this way, the support P is erected. Note that the unit column can be made of metal or synthetic resin.

Further, the unit column may be solid. Stays Ql and Q2 are stretched between two sets of opposing side walls of the tank, respectively.

The stays Q1 and Ql intersect near the support P in the tank.

Among them, the stay Q1 is inserted into the groove 21 in the protruding piece 2 of the column joint A, and is supported on the groove wall 22.

The stay Q2 is supported near the support P by contacting the stay Q1 from above.

In this way, deflection of the stays Q1 and Ql is prevented.

The joint for a tank support according to this invention is a joint in which a protruding piece is attached to the side surface of a columnar body, and a groove is provided in the protruding piece to penetrate linearly from one side to the opposite side, and the groove is formed in the depth direction. Since it is bent, when the stay is fitted into the groove, the vibration of the stay is suppressed.

Therefore, the both end fixing parts are prevented from loosening or being destroyed due to vibration of the stay.

Further, since a groove wall extending perpendicularly to the axis of the columnar body is formed at the bent portion of the groove, the stay can be stably supported when placed on the groove wall.

Furthermore, since the groove runs through the stay in a straight line, the stay can be extended straight and supported.

When a strut is assembled using the strut joint according to this invention and the stay is supported, the stay is supported on the strut, and the stay and the strut prevent each other from vibrating.

Therefore, the reinforcing action of the stay and the pillar becomes even more reliable.

Moreover, since the strut joint according to this invention has a simple structure, it can be supplied at low cost.

This invention provides significant advantages as mentioned above.
