Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to assembled water tanks, and in particular proposes an effective seismic reinforcement structure in which a water tank panel is provided as an assembly of unit panels constituting the side walls of the tank. It is.

(Prior Art) Conventionally, as a means for reinforcing the side wall of such an assembled water tank, an angle material as a reinforcing piece is attached to one flange of each unit panel and stitched together, and a T-shape is attached to the same part of the cross-shaped flange of each one of the unit panels. Attaching a presser foot with cross-shaped or cross-shaped grooves (Jitsukaisho)
55-61584)) are being carried out.

However, regarding the assembly of unit panels constituting the side wall, for the single flange joint ends of the unit panels that face the ridge of the assembled water tank and are in contact with each other,
Even if the above-mentioned presser foot is used, the effect of reinforcing the side wall is not achieved by it, so it is not sufficient as an earthquake countermeasure.

To illustrate this difficulty in more detail, Figure 1 shows
The entire conventional panel-assembled water tank is shown in a perspective view, and FIG. 2 is an exploded view of the same part of the four unit panels.

That is, a large number of unit panels 1 are attached to each other using bolts, with the flange 2 provided around the periphery of the unit panel 1 facing outward. A reinforcing piece 3 made of wood is attached and bolted together.

At the portion where the flanges 2 meet in a cross shape (hereinafter referred to as the cross shape portion), that is, at the intersection where the four corners of the unit panel 1 meet in a cross shape, there is a presser foot with a cross groove, or a T-shaped groove in the illustrated example. 4 was bolted to the aquarium panel.

(Problems to be Solved by the Invention) Figures 3 and 4 are enlarged side views of the same part of the cross-shaped flange, and show that the unit panels are separated by water pressure P based on the internal water storage of the water tank or seismic force. 1 is deformed outward (Fig. 4), the reinforcing piece 3 is supported by the presser foot 4 only at one end that spans the entire inner normal length of the one flange 2, and the other end, that is, forms the side wall. At the joint ends of the unit panels facing the ridge of the assembled water tank (such as parts A, B, and C in Figure 1) of the assembly of unit panels, the other end side of the reinforcing piece 3 is supported exclusively. Depending on the shearing force of the bolt 5, if stress is concentrated on this, there is a possibility that the assembled water tank will be damaged from this part.

That is, even when the conventional reinforcing piece 3 is used, it is not sufficient for seismic reinforcement, and even if the above-mentioned damage does not occur, it is difficult to avoid water leakage.

The invention aims to advantageously overcome the above-mentioned disadvantages.

(Means for Solving the Problems) This invention provides a method for stacking a large number of unit panels each having continuous one-sided flanges on the periphery of a rectangle vertically and horizontally, with the one-flanges connected to each other, and connecting the pieces to each other. For each flange, a reinforcing piece made of angle material with two sides along both edges and one back side opposite to the joint surface is installed along with one flange, and the reinforcing piece is attached to one flange. The side wall of the storage tank is fastened with bolts and nuts arranged in a row, and the side wall of the storage tank has a presser foot having a cross groove that covers one end of each of the reinforcing pieces occupying the intersection where the four corners of the unit panel meet in a cross shape. of,
In an assembled aquarium that is further strengthened by being fastened to an aquarium panel, the reinforcing piece occupies a T-shaped intersection where the two corners of the unit panel are aligned along each edge of the assembled aquarium,
A second presser foot having an overlapping groove at the other end separated from the fastening portion by the presser foot is attached to both sides of the aquarium panel through a threaded sleeve located between the second presser foot and the aquarium panel. This seismic reinforcement structure for an assembled water tank is characterized in that both ends of the reinforcing piece are restrained and fixed by fastening with bolts.

(Function) The present invention has the above-described structure, and in particular, the reinforcing piece 3 made of an angle material that is fastened together to the flanges 2 and 2 is fixed by the presser foot 4 and the second presser foot 6. Both ends are restrained against the aquarium panel, so when assembling, the single flanges 2, 2 and the reinforcing piece 3
Even if the outer edges of the flanges 2, 2 try to shift due to the tolerance of the bolt holes arranged in a row, the flanges 2, 2 are pressed together by the reinforcing piece 3 made of Hunguru material, and the flanges 2, 2 are aligned in a state where the misalignment is resolved. This reinforcing piece 3 is screwed onto the aquarium panel with the second presser foot 6, especially at the T-shaped intersection where the two corners of the unit panel are aligned along each stacked side of the assembled aquarium. Since it is fastened and supported at both ends, the assembled water tank can be more fully reinforced, avoiding the disadvantage of countering water pressure and earthquake force only with the shear force of the fastening bolts of the flanges 2, 2 and the reinforcing piece 3. This not only improves seismic resistance but also reliably prevents water leakage.

In addition, by using the threaded sleeve 9 to fasten the second presser foot 6, it is possible to use shorter bolts than the inside and outside of the water tank during assembly work, and the number of work steps can be significantly reduced.

(Example) A specific example of this invention is shown in Fig. 5 a and b.
In the figure, 6 is the second presser foot, and 7, 7 is the bottom unit panel 1 in this example.
One flange 2b, 2b at the corner of b, 1b
These washers 7, 7 are attached to the bottom unit panels 1b, 1b, and are connected together with the tightening bolts 5b, sandwiching the adjacent flange 2b of the bottom unit panel 1b, and also the remaining flange 2b. The bolts 8 passing through the side unit panels 1s, 1s adjacent to each other laterally on the side walls are screwed into and fixed to the threaded sleeve 9 through the bolt holes drilled at 2b.

On the other hand, a bolt 11 is inserted into the threaded hole sleeve 9 through a second presser foot 6 having a groove 10 that covers the reinforcing piece 3 made of scalene angle material attached to the adjacent flanges 2s, 2s of the unit panels 1s, 1s. The joint ends of the flanges 2s and 2s are screwed together to restrain and fix them. Reinforcement piece 3 has bolt 1 on one flange 2s.
2 and nuts 13, and the reinforcing piece 3 has a short side 3a that covers the outer edge of this piece flange 2s, and the reinforcing piece 3 has a short side 3a that covers the outer edge of the second flange 2s.
0 has a width that allows this short side 3a to fit.

In this example, the threaded sleeve 9 is located between the unit panel 1s and the second presser foot 6, and the bolts 8 and 11 are screwed into the threaded holes from both sides.

FIG. 5c is a partially cutaway side view showing the relationship between these three components.

Because of this structure, the flange 2s is firmly fastened by the presser foot 4 and the second presser foot 6 at both ends of the reinforcing piece 3 that spans the entire length of the flange 2s, and the side wall of the assembled aquarium is completely reinforced. This significantly improves work efficiency during assembly.

Fig. 6 shows an example of application in part B of Fig. 1, and 14 in the figure indicates corner reinforcing angle columns along the flanges 2s, 2s of the side unit panels 1s, 1s at the four corners of the panel-type assembled water tank. In addition to being shown, 6 is also a second presser foot, 7 is a washer, 8 is a bolt, 9 is a threaded sleeve, and 11 is a bolt.

Fig. 7 is an example of application to section C in Fig. 1; in this case, except for using a flat washer 7',
Parts that are the same as those already mentioned are given the same numbers, so the method of fastening is clear.

(Effects of the Invention) As described above, according to the present invention, for an assembly of unit panels constituting the side wall of a panel-assembled water tank, one flange of the panels that face the ridge of the assembled water tank and are in contact with each other on the sides is , Since the reinforcing piece made of angle material attached to this was restrained between each panel by a presser foot and a second presser foot, the joint strength of these flanges was made uniform, which greatly improved the strength of the joint. The seismic strength of this type of aquarium can be increased.

Furthermore, the use of a threaded sleeve made assembly work much easier.
