DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching an inner wall plate of an aquarium for bonding an inner wall plate for making the inner wall of the aquarium smooth.

[0002]

2. Description of the Related Art Many of the inner walls of conventional aquariums, for example, aquariums for fish farming, have rough surfaces with exposed concrete surfaces, and the fish bodies are damaged when the fish farmed in the tanks strikes the rough surfaces. In addition, in order to prevent the sales from being reduced due to being excluded from the sales target, there are also those in which tiles having a smooth surface are provided on the inner wall surface of the aquarium.

[0003] In addition, the surface of which the applicant has already filed has a smooth surface such as an acrylic plate, and a pattern similar to the surrounding environment where fish inhabits is drawn on the back surface, and the inner wall through which the pattern can be seen from the front surface. Attaching the face plate to the wall surface of the aquarium prevents the aquaculture from being damaged, and feels that the aquaculture is growing in a natural habitat. Therefore, aquariums capable of maintaining good growth have been used.

[0004]

However, when a tile is placed on the wall of the aquarium, it is possible to prevent the fish from being damaged. However, not only is the equipment cost for placing the tile on the concrete surface of the aquarium expensive, but also the tile is made of concrete. Since it is easy to peel off from the surface, the maintenance cost for repairing it is also increased, and as a result, there is a disadvantage that the fish farming is expensive.

[0005] When the inner wall plate is stuck in a water tank, a polymer containing a resin or a curing agent is used as an adhesive. However, the polymer takes a long time to cure and exhibit adhesive strength. During that time, the water tank and the inner wall plate were separated, and it was difficult to firmly adhere.

For this reason, a pressing device for pressing the inner wall plate against the wall surface of the water tank is installed in the water tank. However, the pressing device hinders the installation work of the inner wall plate, so that the construction period becomes longer. In addition, the amount of temporary material for attaching the inner wall plate such as the above-described pressing device or the like increases, thereby increasing the cost of attaching the inner wall plate.

Further, if a strut is used as a pressing device, its length becomes long and it is easy to bend, so that a sufficient pressing force cannot be obtained. If a frame material is used instead, it is difficult to swing around. In addition, the work of installing and removing these temporary materials increases, and not only does the work cost increase, but also the number of machines that damage or damage the inner wall plate increases.

In particular, if the four corners of the aquarium are curved,
Since the protection plate, the holding frame, and the like of the inner wall surface plate must also be formed in a curved surface, the cost of forming the curved surface is increased, the cost is further increased, and it is difficult to press the curved surface.

The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an inner wall plate such as an acrylic plate with a long solidification time on an aquarium wall having a concrete surface exposed. It is an object of the present invention to provide a method for mounting a water tank inner wall plate that can be firmly and easily bonded even with an adhesive.

[0010]

Means for Solving the Problems The method for mounting the inner wall plate of the water tank of the present invention achieves the above-mentioned object, and the method comprises applying an adhesive to the wall surface of the water tank to which the inner wall plate is attached,
In the state of temporary adhesion with the inner wall plate overlaid on the water tank wall surface, a mounting hole is drilled from the inner wall plate to a predetermined depth in the water tank wall surface, an anchor is inserted into this mounting hole in the water tank wall surface, and screws are inserted into the inner wall plate. Screwing into the anchor from the outside of the anchor, fixing the anchor in the tank wall by expanding the outer diameter of the anchor, and pressing the screw to press the inner wall plate against the tank wall with the screw head,
After the adhesive is cured, the screw and the anchor are removed, and the mounting hole is closed with a closing member.

[0011] In the above method, a pressure contact member extending over a plurality of screws is interposed between the screw head and the wall plate,
Alternatively, it is desirable that the press-contact member be fixed to the support frame provided in the water tank with the screw.

[0012]

FIG. 1 shows a first embodiment of the present invention.
2 will be described below. In this embodiment, an acrylic plate having a smooth surface and a depiction corresponding to the atmosphere of a fish habitat on the back surface is referred to as an acrylic surface on the concrete wall surface of the aquarium where the concrete is exposed. And an inner wall plate having a reinforced plastic plate (FRP) on the back side.

A polymer 2 containing a resin or a hardening material is applied as an adhesive to the exposed concrete wall 1 of the water tank, and the inner wall plate 3 is temporarily pressed to a predetermined position, and the inner wall plate 3 is pressed. A mounting hole 4 having a predetermined diameter reaching a required depth in the concrete wall surface 1 is drilled from above using a rotary hammer drill or the like.

An example of a drill used at this time is a rotary hammer drill TE5-D manufactured by Nippon Hilti Co., Ltd. The drilling position of this mounting hole is a condition of the concrete wall surface 1, for example, a reinforcing bar position, a crack position. It is desirable to drill the mounting hole 4 except for this.

A commercially available plastic anchor 5 is inserted into the mounting hole 4 and a predetermined screw 7 into which the washer 6 or the holding plate is fitted is screwed into the anchor 5 as shown in FIG. The screw 5 is screwed into the anchor 5
The skirt portion is expanded and strongly pressed against the inner wall surface of the mounting hole 4, and the anchor 5 itself is fixed in the mounting hole 4.

An example of the plastic anchor 5 is a plastic anchor H manufactured by Japan Hilti Co., Ltd.
PS-1 is provided, and the screw 7 is continued to be screwed in thereafter, so that the washer 6 fitted thereto presses the inner wall plate 3 against the concrete wall 1 at the pitch of the screw 8, and this state is changed to the polymer 2 Continue until is cured.

Thus, the polymer 2 cures,
After the inner wall plate 3 is bonded to the concrete wall surface 1, the screws 7 screwed to the anchors 5 are rotated in a loosening direction,
The bulge of the plastic part of the anchor 5 returns and is released from the mounting hole 4.

When the screw 7 is retracted to the extent that the plastic portion of the anchor 5 and the screw 7 are screwed together, the screw 7 is fixed to the concrete wall surface 1 with the washer 6 and the plastic portion of the anchor 5 attached. Remove from the inner wall plate 3.

As shown in FIG. 2, the mounting hole 4 from which the anchor 5 has been removed is slightly longer than its depth.
An acrylic round bar 8 having the same diameter as the mounting hole 4 is immersed in an acrylic solvent and inserted into the mounting hole 4 until it touches the inside.

After the acrylic solvent is dried and the acrylic round bar 8 is fixed to the concrete wall surface 1 and the inner wall plate 3, the portion 8a where the acrylic round bar 8 protrudes from the inner wall plate 3 is flush with the inner wall plate 3. Then, the cut surface is polished and finished, and the work of attaching the inner wall plate 3 to the concrete wall surface of the water tank is completed.

In the second embodiment shown in FIG.
When the screw 7 is screwed into the anchor 5 in the previous embodiment, the iron angle reinforcing material 10 in which the insertion holes 9 are drilled at the same intervals as the mounting holes 4 already drilled is placed on the insertion holes 9. And a screw 8 is screwed into the anchor 5.

Since the reinforcing member 10 is pressed against the inner wall plate 3 over its longitudinal direction by the tightening of the screw 7, the inner wall plate 3 is pressed against the concrete wall 1 over the entire length by the strength of the reinforcing member 10, and In this embodiment, the inner wall plate 3 is pressed against the concrete wall 1 only at the anchor 5 and incomplete bonding due to insufficient pressing at other portions can be prevented.

In the third embodiment shown in FIG.
At the same time that the reinforcing material 10 is supported by the screw 7 with respect to the previous embodiment, the oblique pillar 11 having one end fixed to the bottom of the water tank is provided.
Is fixed together with the reinforcing member 10 with the screw 7 to further enhance the reliability of pressing against the inner wall plate 3.

[0024]

As described above, according to the present invention, since the adhesive used for attaching the inner wall plate having a smooth surface to the wall surface of the aquarium is a polymer containing a resin or a hardening material, the adhesive is cured to improve the adhesive strength. It takes a long time to exhibit, and during that time, the water tank and the inner wall plate can be kept in a pressure contact state for a necessary time so that strong adhesion is possible.

In addition, the pressing device which was required for pressing the inner wall plate against the wall surface of the water tank in the related art is no longer necessary. Since the inner wall plate is pressed against the concrete wall surface with the screw screwed to the anchor, the screw, the reinforcing plate, etc. do not hinder the work, and the inner wall plate can be attached without any trouble.

Therefore, the construction period can be shortened, and since the temporary material such as the pressing device is not used and the work of installing and removing the temporary material is not required, the cost of mounting the inner wall plate is reduced. This can reduce the number of machines that damage or damage the inner wall plate due to the swinging of temporary materials.
