Description

[Detailed Description of the Invention] This invention relates to a heat insulating side wall unit panel for a panel assembly type aquarium.

In general, a panel-built aquarium has a rectangular shape, such as a square or a rectangle, with a common aspect ratio suitable for dividing the surrounding walls, i.e., the side walls, the bottom wall, and possibly the ceiling wall. Each periphery has a flange bent and projecting outwardly of the prefabricated aquarium, the flange preferably having a face plate with a plurality of holes arranged in a row as close as possible to the roots. These unit panels are assembled by mutually fastening them with bolts, nuts, rivets, etc. using the flanges of these unit panels.

Therefore, depending on the number of unit panels used, a container of any desired volume can be easily assembled, and management after assembly is easy and hygienic. Another example is underground water tanks, where demand is rapidly increasing.

It is basically known that in order to insulate this type of panel-assembled aquarium to prevent freezing, for example, a heat insulating layer such as rigid polyurethane foam is usually attached to the flange side, that is, the outer surface of the face plate. One example is one in which a heat insulating layer is attached to the faceplate, leaving a small area around the flange, and another in which the heat insulating layer is extended to the base of the flange to enhance the heat insulating effect. 50 = No. 34121, No. 66213, No. 145919
There are various publications (issues, publications, etc.).

However, in the case of the former type with a flange, the root is excluded from the heat insulating coating, so in the case of a flange type with a hole drilled near the root, the fastening work in the hole is simple and a strong assembly is possible, but the insulation properties are poor. On the other hand, although the latter has excellent insulation properties, it is difficult to insert and tighten bolts and rivets into the flange's binding holes, so it is recommended to extend the flange and fasten it at the outer edge away from the root. However, the strength of the assembly weakens as the fastening position moves away from the root of the flanged joint.

In addition, especially the side wall of the prefabricated water tank due to the above-mentioned fastening,
Similarly, when fastening the face plate flange of the unit panel used for the bottom wall with the face plate of the side wall unit panel using the hole, the face plate of the side wall unit panel If a heat insulating layer is provided that covers the entire outer surface of the aquarium, it will be necessary to tighten the heat insulating layer between them, making it difficult to ensure a strong enough fastening to withstand the water pressure at the bottom of the tank. The same is true between the side walls and the ceiling wall, except for the influence of water pressure.

Therefore, this invention aims to provide a side wall unit panel that is fastened to the flange of the bottom wall or ceiling wall unit panel at one edge of the face plate, especially one having a heat insulating layer. The purpose of this invention is to improve the heat insulation performance over the entire outer surface of the face plate without causing disadvantages such as a decrease in assembly strength or deterioration of assembly workability.

This invention consists of a face plate that has a rectangular aspect ratio that divides the prefabricated aquarium surrounding wall and has flanges that are bent and protrude outward from the prefabricated aquarium at the four peripheral edges, and all of the flanges and A side wall unit in which a plurality of fixed holes are arranged in rows along the edge of the face plate along one of the holes, and the side wall unit is used for assembling an aquarium by fastening between the flanges and between the flanges and the edge of the face plate. The panel P has a heat insulating layer covering the entire outer surface of the face plate, and this heat insulating layer is characterized in that at least the edges of the face plate have partial cutouts at positions corresponding to the holes. This is an insulating side wall unit panel for a panel assembly type aquarium.

In addition, with this invention, the heat insulating layer has partial notches at the four peripheral edges of the face plate at positions corresponding to the holes in each flange, and furthermore, these notches form a part of the heat insulating layer that fits. It is preferable to implement it in a form that can be combined with pieces.

Now, Fig. 1 shows the main parts of an embodiment of this invention for a panel assembly type insulating water layer surrounding six sides including the ceiling.

In the figure, 1 and 2 are the front and left side walls, and 3 is the top wall.Although not shown in the figure, the rear and right side walls, and the bottom wall are also units that are almost similar to the above-mentioned side walls and top wall. Panels P are used to connect them to each other using flanges around the four sides.

As shown for one of the corner portions of the front and left side walls 1 and 2, the four corners between the side walls are mutually fastened at a portion of the corner by an angle member 4 and a flange.

FIG. 2 shows a side wall unit panel P with flanges 6 bent toward the outside of the prefabricated aquarium at the four peripheral edges of the rectangular face plate 5, as shown in a cutaway view of the main part of the side wall unit panel P. For all of 6, the attachment should be as close to the root as possible,
Angle material 5 between flanges 6 or part of the above corner
A hole, for example bolt hole 7, is used for fastening between the
, and similar bolt holes 15 are arranged in a row on the edge of the face plate along one of the flanges.

In addition, the face plate 5 can be formed into a convex shape with a swollen center in order to increase its pressure resistance.

Note that Figure 1 shows the case where two tiers of panels are stacked in the height direction, so although it is not shown in the figure, when there are three or more tiers, 9 panels are placed on the side wall unit panel of the intermediate tier that is not adjacent to the bottom wall or top wall. Similarly, those for the bottom wall and the top wall do not have bolt holes 15 on the edge of the face plate.

These unit panels are made of molded iron plates or fiber-reinforced plastics, and a heat insulating layer 8 as shown in FIG. An integral structure is formed by foam molding or by adhering the molded product.

The heat insulating layer 8 is adhered to the face plate 8 in order to reduce the burden on dimensional accuracy during processing and to avoid concerns about peeling due to external force impact acting on the assembled container or thermal expansion differences due to temperature changes. First, a thin soft foam layer 9 is applied to the outer surface of the
If the above-mentioned procedure is adopted in which the heat insulating layer 8 is pasted on top of the heat insulating layer 8 as shown in Figure 3, the tolerance for dimensional errors will be widened due to the buffering effect of the elasticity of the layer 9, and damage to the assembly will be avoided. This has the advantage that the heat insulating effect can be improved due to the close contact of the heat insulating layer 8, and it is also advantageous in preventing dew condensation on the surface of the face plate.

It is preferable that a protective coating 10 made of a thin layer of FRP is further formed on the surface of the heat insulating layer 8.

The heat insulating layer 8 that covers the entire surface of the face plate 5 as described above has notches 1 at positions corresponding to the bolt holes 7 of the flange 6.
1, and it is desirable that a heat insulating filling piece 12 as shown in FIG. 3 be provided in the notch 11, preferably integrally with the heat insulating layer 8, so as to be able to rise and fall.

As shown in FIG. 3, this notch 11 is formed by attaching the flange 6, inserting the bolt 13 into the bolt hole 7 opened close to the root, and tightening the nut 14 using a heat insulating layer.
It is convenient to avoid the flanges from getting in the way and to advantageously enable firm tightening of the flanges. Furthermore, after the above-mentioned fastening, the insulation filling piece 12 is inserted into the gap between the head of the bolt 13 or the nut 14. Push it into the notch 11 and fix it.
It is possible to advantageously improve the deterioration of the heat insulation properties in the cutout portion 11,
Although the heat insulating filling piece 12 may be prepared separately, it is convenient to mold it integrally with the heat insulating layer 8 as described above without fear of loss.

In this invention, as shown in FIG.
1 must be provided approximately concentrically with a bolt hole 15 arranged on the edge of the face plate 5 along one of the four circumferential flanges (most of which are shown in broken view), and this should be provided on the bottom wall or the top of the side wall 2. It is used for the unit panel P adjacent to the wall 3, and is used for direct connection between the face plate 5 of the side wall unit panel P and the flange 6 of the unit panel constituting the top wall 3, especially the bottom wall 16, as shown in FIG. That's what I do.

When the face plate 5 and the flange 6 are fastened together, the notch 11 prevents the heat insulating layer 8 from being pinched between the bolt head and the nut or washer, so that strong fastening does not result in any deterioration of workability. It can be secured without any problem.

In addition, the heat insulating properties can be further improved by similarly using the heat insulating filling piece as already described in the gap around the pole 1 to the head or nut in the notch 11.

FIG. 4 shows a bottom wall unit in which a unit panel is deformed to form a drainage basin 17 at the corner of the bottom wall 16, and a central convex protrusion 18 is provided with the center swollen toward the inside of the tank. An example is shown in which it is used with panel P'.

For the top wall 3, a deformable unit panel (not shown) may sometimes be used that has a heat insulating layer inside the tank.

Thus, according to this invention, unit panels of small types can be appropriately combined and secured by connecting flanges to each other or to the face plate of the unit panels, without impeding assembly workability in any way. , it is possible to advantageously and easily achieve strong fastening of unit panels and maintenance of heat insulation within the tank.
