Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled water tank, and in particular proposes seismic reinforcement of a panel assembly constituting the side wall of the tank.

0002

[Prior Art] Conventionally, as a means for reinforcing the side walls of such an assembled aquarium, the method of attaching scalene angle members to the flanges of each panel and binding them together, and also providing a T-shaped groove in the same part of the cross-shaped part of each flange. Either or both of attaching a butt may be used. However, for each panel assembly that makes up 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 it 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 four panels shown in FIG. 1. That is, a large number of panels 1 are attached with the flanges 2 provided around the panels 1 facing outward, and the flanges 2 are bound together with bolts. Garnish with the ingredients and stop with porto. In this example, a backing plate 4 having a T-shaped groove may be bolted to the part where the flanges 2 meet in a cross shape between the backing panel 2 and the backing panel 2.

FIGS. 3 and 4 are enlarged side views of the cross-shaped portion of such a flange, and show the water pressure P based on the internal water storage of the water tank.
Alternatively, when the panel 1 is deformed outward due to earthquake force or the like (Fig. 4), the scalene angle member 3 is supported by the pad 4 at only one end, and the other end, that is, the panel assembly forming the side wall. Therefore, at the joint ends of the panels that face the ridge of the assembled water tank and come into contact with each other (such as parts A, B, and C in Fig. 1), the restraint of the unequal angle members 3 depends exclusively on the shear force of the ports 5. ,
Stress will be concentrated in this area and the assembled water tank will be damaged from this area. In other words, even when the conventional unequal leg angle members 3 are used, they are not sufficient for seismic reinforcement, and even if the above-mentioned damage does not occur, water leakage cannot be avoided.

SUMMARY OF THE INVENTION The object of the invention is to advantageously overcome the above-mentioned disadvantages, particularly with respect to the mutual joints of the side walls and the horizontal walls, such as the bottom wall.

[0006]

[Means for Solving the Problems] The present invention provides an assembly in which four side walls are constructed together with a horizontal wall by butt-joining a large number of rectangular panels each having a flange formed by bending all the peripheral edges to one side, with each flange facing outward. In the aquarium, for the panel assembly constituting the side wall, there is a Apply a scalene angle member with a short piece covering the outer edge and tighten together with bolts and nuts, and attach a presser foot with a groove that covers the short piece of the scalene angle member across the joint end of the flange. , between the presser foot and the flange of the horizontal panel through the panel corresponding to the flange, a short piece of scaleless angle material is pressed and fixed with bolts and nuts to connect the side wall and horizontal wall of the assembled aquarium. This is an earthquake-resistant reinforcement structure for the joints.

[0007] The present invention has the above-mentioned configuration, 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 can be completely absorbed. The reinforcement is complete. FIGS. 5(a) and 5(b) show a specific example of the seismic reinforcement structure of the mutual joint between the side wall and the bottom wall according to the present invention, when applied to the reinforcement of section A in FIG. 1, where 6 is a presser foot. , 7, 7 are L-shaped washers attached to the flanges 2b, 2b at the corners of the bottom panels 1b, 1b in this example;
In addition to sandwiching the adjacent flanges 2b and 2b and joining them together with their fastening bolts 5b, the side panels 1 adjacent to each other next to the side walls are connected through bolt holes drilled in the remaining flanges 2b.
A spacer 9 is fitted to the restraining bolt 8 passing through the panels 1s, 1s, and the adjacent flanges 2s,
The presser foot 6 having a groove 10 that covers the angle material 3 attached to the side panel 1s is secured with a nut, and the side panel 1s,
1s through the bottom wall panel 1b, flange 2b of 1b,
2b, the joint ends of the flanges 2s, 2s are restrained and fixed.

The unequal leg angle member 3 is fastened to the flange 2s with bolts 12 and nuts 13, and the unequal leg angle member 3 has a short piece 3a that covers the outer edge of the flange 2s. The groove 10 of the presser foot described above has a width sufficient to fit this short piece 3a. In the figure, 14 is a nut that is screwed onto the bolt 8. Note that instead of the spacer 9, a nut (not shown) screwed onto the restraining bolt 8 on the side panel 1s or presser foot 6 may be used.

For reference, FIG. 6 shows an example of the reinforcement method in section B in FIG. 6 is a presser foot, 7 is a washer, 8 is a restraining bolt, and 9 is a spacer. For further reference, Figure 7 shows an example of the reinforcement procedure for section C in Figure 1. In this case, except for using a flat washer 7', parts that are common to those already described are given the same numbers. From what has been expressed, the gist of the conclusion 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 panels adjacent to the bottom wall panel assembly on the sides facing the ridge of the bottom of the assembled water tank are The flange is restrained between each panel by an angle attached to the flange, and the joint strength of these flanges is made uniform, so that the seismic strength of this type of aquarium can be significantly increased.
