Description

[Detailed Description of the Invention] This invention relates to a bottom of an assembly container equipped with a stay lock.

It has already been practiced to assemble large containers such as tanks from a number of unit plates. Examples of such unit plates include a rectangular base plate with upright joint edges on all four sides (Japanese Utility Model Publication No. 40-27399);
A rectangular base plate with inclined and upright joint edges on all four sides has been used (Japanese Utility Model Publication No. 42-3963). However, when a large container assembled from such unit plates is filled with liquid, the side walls tend to sag and bulge outward. To prevent this sagging, it was considered to attach a stay at an angle between the bottom and the side walls.

In order to attach a stay between the bottom and the side wall,
It is necessary to fix both ends of the stay diagonally to the bottom or side wall. However, it is not easy to fix both ends of the stay diagonally directly to the bottom or side wall. Therefore, in order to make fixation easier, it is possible to use a block with a standing wall on a flat plate (hereinafter referred to as a stay block), fix the flat plate to the bottom or side wall, and fix the end of the stay to the standing wall. Ta.

However, when the stay is fixed between the bottom and the side wall as described above, if the side wall is forced to bend outward, force is applied in the direction in which the stay lock is lifted, and as a result, the bottom This resulted in the disadvantage that the stave lock fixing portion of the unit plate was destroyed or the bottom of the unit plate was lifted up. This invention was made to improve the above-mentioned drawbacks.

That is, this idea involves arranging the shaped steel in a grid pattern with the flat side of the shaped steel facing upward, connecting them to each other to form a frame, and arranging a large number of unit plates on the frame.
The unit plate shall consist of at least a right-angled rectangular substrate and a joining edge attached to its periphery, and the tip of the joining edge shall be in contact with the flat surface of the section steel, and two unit plates shall be placed on the intersection line of only the two unit plates. At the bottom of an assembly container in which a stave lock that spans only the unit plates is fixed, a hard plate is provided at a position that sandwiches the unit plate and faces the stay lock, and the hard plate is connected only to the section steel that is under the above intersection line. This is the bottom of an assembly container in which bolts are passed through the stave lock, unit plate, and hard plate, and these are fixed to the section steel.

The bottom of the assembly container according to this invention will be explained as follows based on the drawings. FIG. 1 is a partially cutaway exploded perspective view showing an example of the bottom of the assembly container of this invention. FIG. 2 is a partial sectional view showing the same bottom as FIG. 1. FIG. 3 is a partial sectional view showing another example of the bottom of the assembly container of this invention. FIGS. 4 and 5 are perspective views showing an example of a hard plate used in this invention.

In FIG. 1, a tank frame is assembled from H-beams 1A and 1B. Channel steel, angle steel, etc. can be used instead of H-beam steel. H
The shaped steels 1A and 1B are arranged in a grid pattern with the flat surface 11 facing upward, and are coupled to each other.

A large number of unit plates 2A are arranged on the frame.
The unit plate 2A has a right-angled rectangular substrate 21 with
An inclined joining edge 22 is provided which is inclined at an angle of 135 degrees with respect to the substrate 21, and an upright joining edge 23 which is upright with respect to the substrate 21 is provided beyond that. The unit plate 2A is arranged so that the upright joint edge 23 faces downward and its tip contacts the flat surface 11 of the H-section steel. The upright joining edges 23 of adjacent unit plates 2A are brought into contact with each other and fixed with bolts 3 with packing (not shown) in between. The bottom of the tank is thus provided on the pedestal.

At the bottom, a stay lock 4A is abutted on the intersection line where only the two unit plates 2A touch, and straddles only the two unit plates. Stave lock 4A
In this example, three trapezoidal vertical walls 42 are provided in a U-shape on the edge of a right-angled rectangular flat plate 41.

A hard plate 5A is provided at a position sandwiching the unit plate 2A and facing the stay lock 4A. The hard plate 5A is bent into an L shape, and one piece of the hard plate 5A is an upright piece 1 of the H-beam 1A, as shown in FIG.
2 and is fixed with a bolt 3. The other piece of the hard plate 5A projects laterally beyond the flat surface 11 of the H-section steel 1A, and bolt holes are provided in the projecting portion. As shown in FIG. 2, long bolts 6 are passed through the flat plate 41 of the stay lock, the base plate 21 of the unit plate, and the other protruding piece of the hard plate 5A, and tightened with nuts. It is desirable to sandwich the gasket 7 between the flat plate 41 and the substrate 21. In this way, the hard plate 5A, unit plate 2A, and stay lock 4A are fixed to the H-shaped steel. This is the structure of the bottom of the assembly container of this invention.

In order to arrange the above H-beams in a grid pattern, a long H-shaped steel
It is also possible to arrange the section steel in parallel and arrange the short H section steel orthogonally to the long H section steel between them, but as shown in Fig. 1, the H section steel is cut to a certain length and cut. 1A is made of two planes that intersect with each other, both of which are perpendicular to the flat surface 11 and inclined at 45 degrees with respect to the longitudinal direction, and four cut H-beams are made. It is convenient to arrange them so that 1A constitutes one square. Note that the H-shaped steel used for the periphery of the frame may have only one of the two planes inclined at 45 degrees. Also,
As shown in Fig. 1, V-shaped notches 13 are provided at regular intervals on one side edge of a long H-beam 1.
It may be B. To join the H-shaped steels arranged as above, it is possible to weld, but it is also possible to connect the L-shaped connecting fittings across the joints of the H-shaped steels that are perpendicular to each other, and fix them with bolts. is convenient.

In the unit board 2A, the center portion of the substrate 21 may bulge toward the protruding side of the joint edge or the opposite side. Moreover, instead of the unit plate 2A, a unit plate formed by providing only upright joint edges around the four circumferences of the substrate can be used. These unit plates are preferably made of iron or reinforced synthetic resin. In addition, the side wall of the tank is
It can be assembled with unit plates of the same or different type as the bottom.

The above-mentioned stay lock 4A and hard plate 5A are
Preferably made of metal such as iron. Further, it is desirable that bolt insertion holes 43 be provided in the flat plate 41 and the vertical wall 42 of the stay lock 4A. A diagonal stay 8 is fixed to the vertical wall 42. Instead of the stay lock 4A, a stay lock having a flat plate with a standing wall in the center can be used. Moreover, a flat hard plate can be used instead of the hard plate 5A. In this case, the hard plate is
It is desirable to fix it to either of two parallel pieces of section steel. In addition, the hard plate may be brought into contact with the lower side of the H-shaped steel, and both side edges may be made to protrude to both sides of the H-shaped steel.

Instead of the long bolt 6, a double-threaded bolt may be passed through a disc and welded at the penetrating position. In this case, it is desirable to insert one screw from the bottom to the top of the stay lock, and the other screw from the top of the unit plate to the bottom of the hard plate, and tighten them with nuts.

At the bottom of the assembly container of this invention shown in FIG. 3, a unit plate 2 is used instead of the unit plate 2A in FIGS.
The bottom of the tank is assembled using B. The unit plate 2B has only upright joining edges 23 provided on the four peripheries of a right-angled rectangular substrate 21. Also, the first
In place of the stay lock 4A in Figures and Figure 2,
A stay lock 4B is used. The stay lock 4B has a flat plate 41 and a standing wall 42 in the center thereof. In addition, as a stay lock,
Various other materials can also be used. For example, the flat plate may have any shape such as circular or octagonal, and the vertical wall may have a rectangular, pentagonal, hexagonal, cylindrical, or square tube. In addition, the standing wall is L-shaped,
They can be arranged in a T-shape, cross-shape, or the like. It is desirable that the standing wall stand perpendicular to the flat plate.

At the bottom of the assembly container described above, a rigid plate 5B or 5C shown in FIGS. 4 and 5 can be used instead of the rigid plate 5A. Hard plate 5 in Fig. 4
B is a hard plate 5A in which a reinforcing piece 51 is provided at the center inside the L-shaped fold.

The hard plate 5C in FIG. 5 has the following features in the hard plate 5A:
Reinforcing pieces 51 are provided at both ends of the L-shaped fold. In addition, the above-mentioned hard plates 5A to 5C are
The L-shaped horizontal piece may be positioned on either the upper or lower side.

At the bottom of the assembly container according to this invention, a pedestal is made by joining shaped steel in a grid pattern, unit plates are arranged on the pedestal, and a stave lock spanning the unit plates is placed on the intersection line of only two unit plates. At the bottom of the fixed assembly container, we installed a hard plate at a position that sandwiched the unit plate and faced the stay lock, and we decided to lock the hard plate only to the section steel located under the intersection line. It is fixed to a section steel midway along the side of the unit plate, so it is easy to fix the hard plate. Further, since bolts are passed through and fixed to the stave lock, the unit plate, and the hard plate, when a force is applied in the direction of lifting the stave lock due to the deflection of the side wall, that force is transmitted to the frame through the bottom. Therefore, there is no risk that the unit plates constituting the bottom will be destroyed or the bottom will float up. This is a major advantage of this invention.

In addition, in this invention, the bolts are passed through the stave lock, the unit plate, and the rigid plate, so that the stay block and the unit plate are fixed, and at the same time, the unit plate and the frame are fixed. Therefore, there is no need to fix the unit plate and the frame again. Further, since the upper end of the bolt is located above the stay lock and the lower end is located below the hard plate, both have the advantage that the tightening tool can easily reach them and the tightening work is easy.
