Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembled water tank, and in particular proposes seismic reinforcement applied to a panel assembly constituting the side wall thereof.

Conventional means for reinforcing the side walls of assembled water tanks include:
Either or both of attaching an angle piece to the flange of each panel and stitching them together, and attaching a stopper with a T-shaped groove to the same portion of the cross of each flange are used.

However, in each panel assembly constituting the side wall, the above-mentioned reinforcement effect does not extend to the flange joint ends of the panels that face the ridge of the assembled water tank and are in contact with each other, so this is not sufficient as an earthquake countermeasure.

FIG. 1 shows a perspective view of the entire conventional panel-type assembly aquarium, and FIG. 2 is an exploded view of the same portion of the four panels. That is, a large number of panels 1 are attached to the flanges 2 by bolting them together with the flange 2 provided around the panel 1 facing outward. Preferably, angle members 3 are attached to the flange 2 as shown in Fig. 2. Stop at Porto.
And at the part where the flange 2 meets in a cross shape, there is a T.
A backing plate 4 having grooves was sometimes bolted to the backing panel 2.

FIGS. 3 and 4 are enlarged side views of the cruciate portion of the flange, and show that when the panel 1 is deformed outward due to water pressure P based on the internal water storage of the water tank or seismic force, etc. The angle member 3 is supported by the stopper 4 at only one end; the other end, that is, the joint end of the panels that face the ridge of the assembled water tank and are in contact with each other on the sides of the panel assembly that constitutes the side wall ( In areas A, B, and C in FIG. 1), the support of the angle member 3 depends solely on the shearing force of the port 5, and stress is concentrated on this, causing damage to the assembled water tank from this area.

That is, even when the conventional angle members 3 are used, they are not sufficient for seismic reinforcement, and water leakage cannot be avoided even if the above-mentioned damage does not occur.

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

This invention provides an assembled aquarium in which a large number of rectangular panels each having a flange formed by bending all the peripheral edges to one side, with the flange facing outward, are butt-jointed to form a four-circumference side wall.
For the panel assembly constituting the side wall, angle members having top surfaces covering the outer edges are applied to the flanges of the panels that face the ridge of the assembled water tank and are in contact with each other on the sides, and are fastened together with bolts and nuts. , a presser foot having a groove that covers the top surface of the angle material is applied across the flange joint end, and the top surface of the angle material is pressed between this presser foot and each panel corresponding to each flange. This is an earthquake-resistant reinforcement structure for an assembled water tank fixed with bolts.

The present invention has the configuration as described above, but in particular, since the flange is reinforced with a presser foot through the angle material fastened together, deviations of the outer edge of the flange due to tolerances during assembly are completely eliminated. absorbed,
The reinforcement is complete.

Figures 5a and 5b show a case in which a specific example of the present invention is applied to reinforcing section A in Figure 1.
is the presser foot, and 7, 7 is the bottom panel 1b, 1 in this example.
It is an L-shaped washer attached to the flanges 2b, 2b at the corner of the bottom panel 1b, and these washers are connected together with the fastening bolt 5b, sandwiching the adjacent flanges 2b, 2b of the bottom panel 1b, 1b. A spacer 9 is fitted into the restraining bolt 8 which passes through the side panel 1s, 1s adjacent to the side wall from the bolt hole drilled in the remaining flange 2b, and the panel 1
A presser foot 6 having a groove 10 that covers the angle material 3 attached to the adjacent flanges 2s and 2s of s and 1s.
Attach the side panels 1s, 1 with nuts.
The joint ends of the flanges 2s, 2s are restrained and fixed between the flanges 2s and s.

The angle member 3 is fastened to the flange 2s with bolts 12 and nuts 13, and the angle member 3 has a top surface 3a that covers the outer edge of the flange 2s. The groove 10 of the presser foot described above is formed on this top surface 3a.
It is wide enough to fit. In the figure, 14 is a nut screwed onto the bolt 8.

Note that instead of the spacer 9, a nut (not shown) screwed onto the restraining bolt 8 to the side panel 1s or presser foot 6 may be used.

FIG. 6 shows an example of application in part B of FIG. 1, in which 15 indicates reinforcing angles along the flange 2s of the side panel 1s at the four corners of the panel-assembled water tank, 6 indicates a presser foot, 7 8 is a washer, 8 is a restraining bolt, and 9 is a spacer.

Also, Fig. 7 is an application example for section C in Fig. 1.
In this case, except for the use of a flat plate-shaped washer 7', parts that are common to those already described are given the same numbers, so the fastening procedure is clear.

As described above, according to the present invention, for the panel assembly constituting the side wall of the panel-assembled water tank, the flanges of the panels that face the ridge of the assembled water tank and are in contact with each other at various sides, and the angles attached to the flanges, The seismic strength of this type of aquarium can be greatly increased since the joint strength of these flanges is made uniform by restraining the space between each panel using a presser foot.
