Description

[Detailed Description of the Invention] This invention relates to a panel-type assembly tank in which a large number of unit panels are interconnected and taken over, and tension rods are stretched between opposing side walls to strengthen the connection.

Conventionally, elevated water tanks installed on the rooftops of high-rise buildings, for example, have been used with various shapes and structures, but each periphery of the rectangular pressure-receiving surface is bent outward to form a mounting flange. This installation is possible using a large number of unit panels connected to each other by flanges.In panel assembly tanks, regardless of their volume, only the required number of rectangular panels need to be removed; It is suitable for producing large quantities of small varieties in panel fly farms, so it is advantageous for producing elevated water tanks.

Reinforced plastics are particularly preferred as materials for the above-mentioned unit panels, but as the shape of the aquarium becomes larger, the internal pressure due to the stored water increases.
It is unavoidable for the side walls of the aquarium to bulge.

In order to minimize this bulge, it is desirable to connect and reinforce the opposing side walls of the assembly tank with a tension rod. It is quite difficult to assemble the aquarium by firmly tightening the unit panel on the side wall to be attached without applying excessive force.
Furthermore, when the aquarium assembled in this manner is filled with water, it is difficult to maintain extremely good watertightness at the attachment portion.

For example, FIG. 4 shows a conventional example in which a tension rod 21 is used to reinforce the side wall 22 of the assembly tank.

In this example, both ends of the tension rod 21 that penetrates the assembly tank are screwed to angle members 23 fixed outside the tank.
A gasket 24 is inserted between the tension rod 21 and the tank wall 22, and the gasket 24 is sandwiched between flanges 25 and 26 fitted onto the tension rod 21.

However, this prior art has the following drawbacks.

That is, in order to attach the packing 24 and the flanges 25 and 26, it is necessary to work both inside and outside the tank, resulting in poor work efficiency.

This also causes many inconveniences, such as the fact that if water leaks, it cannot be prevented from outside the tank, so it is necessary to drain the water from the tank first.

The purpose of this invention is to prevent bulges from forming on the side walls even when a panel-type assembly tank made by interconnecting a number of unit panels is filled with water, and to prevent bulges from forming on the side walls. The aim is to propose a structure that makes it easy to perform water-tight joints on the side walls of panels and to easily deal with water leaks.

The gist of this is that when connecting and reinforcing the opposing side walls of an assembled tank formed by interconnecting a large number of unit panels via flanges, a tension rod is passed through the assembled tank to strengthen the connection. In a structure in which both ends of a tension rod protruding outward are fastened via nuts to a bracket protruding from the flange end, an enlarged diameter portion is provided at a position that hits the inside of the tank separated from the threaded portions at both ends of the tension rod. A rubber bushing with a flange is fitted into the tension rod between the enlarged diameter part and the bracket adjacent to the enlarged diameter part, and the rubber bushing is inserted into the tension rod insertion connecting hole in the side wall of the unit panel. The structure is such that a cylindrical spacer is fitted between the bracket and the flange end of the rubber bushing which is fitted in a watertight manner and positioned outside the tank.

The details of the configuration will be explained below.

FIG. 1 shown in the drawings is a partially cutaway perspective view of a panel-type assembly tank in which a large number of unit panels are interconnected and combined, and opposing side walls are connected and reinforced by tension rods. For the upper and lower surfaces, a square unit panel 1 is used, which is recessed in a truncated pyramid shape toward the center, and on the side wall surface, a square unit panel 1 is used, which is also recessed in a pyramid shape, with the recessed surface facing the inside of the tank. 2, the periphery of each unit panel 1, 2 is bent and connected to each other by a flange 2' to form a panel type assembly tank.

As shown in Fig. 1, a tension rod 3 is stretched between the opposing side walls of the above-mentioned panel type assembly tank to strengthen the connection so as to resist the increase in internal pressure caused by water. As shown in FIGS. 2 and 3, the rod 3 has a threaded portion 3a at both ends and an enlarged diameter portion 3b as a stopper spaced apart from each end, and between the threaded portion 3a and enlarged diameter portion 3b. A flanged rubber bushing 4 with a cylinder length longer than the thickness of the unit panel 2 is inserted between the tension rod 3 inserted through the connection hole 2a of the unit panel 2 and the square panel 2, and a spacer 5 and a bracket 6 are inserted. It is screwed and fixed with a nut 7 through the .

To illustrate the construction order here, the tension rod 3 having the threaded portion 3a and the enlarged diameter portion 3b is inserted into the connection hole 2a of the unit panel 2 from inside the tank, and the flanged rubber bushing 4 is inserted into the tension rod 3 from outside the tank. The cylindrical spacer 5 and the bracket 6, which can be connected to the flange 2', are fitted from both ends of the tension rod 3, and then the nut 7 is inserted. Tighten it firmly.

FIG. 3 shows the state before the tension rod 3 is tightened, but the expanded diameter portion 3b is located inside the tank inner surface of the unit panel 2, and the length of the cylinder under the flange of the flanged rubber bushing 4 is the same as that of the unit panel 2. It is necessary that the thickness of the panel 2 be larger than that of the panel 2.

Note that if the expanded diameter portion 3b is located far away from the inner surface of the tank, even if the cylindrical length of the flanged rubber bushing 4 is longer than the thickness of the unit panel 2, the connection hole after tightening the tension rod 3 will be removed. The tension rod 3 should be designed so that the expanded diameter portion 3b is not far away from the inner surface of the tank since the watertightness at the portion 2a is reduced.

Further, the outer diameter of the flange of the rubber bushing 4 needs to be larger than the inner diameter of the connecting hole 2a provided in the square panel 2.

On the other hand, the tension rod 3 is made of a rigid material such as an iron rod, and by connecting two or three rods together in a tank, the tension rod 3 has a threaded portion 3a and an expanded diameter portion 3b at both ends. If the tension rod 3 is used, the workability will be extremely good, and if the length is adjusted appropriately when joining to optimize the position of the enlarged diameter part 3b, watertightness, which will be described later, will be further improved. .

To tighten the tension rod 3 shown in FIG. 3, in the previous state, when the nut γ is gradually tightened from outside the tank using the threaded portion 3a of the tension rod 3, the tension rod 3 is tightened as shown in FIG. 2 by the action of the expanded diameter portion 3b. Tip 4a of rubber bush 4
bulges out, and the flange portion 4b also comes into close contact with the outer surface of the square panel 2.

Therefore, the unit panel 2 is not drawn into the tank more than necessary, and the unit panel 2 can be firmly tightened without applying excessive force.

Furthermore, when the above-mentioned assembly tank is filled with water, the unit panel 2 is pushed outward by the water pressure, but in this case, the outer surface of the unit panel 2 and the flange portion 4b of the rubber bushing 4 are sealed. In addition, the tension of the tension rod 3 can prevent the side wall of the aquarium from bulging.

As is clear from the detailed explanation above, the panel type assembly tank of this invention has opposing side walls firmly connected by tension rods, so even when the tank is filled with water, water pressure causes bulges on the side walls. It can be used particularly effectively in large assembled aquariums, etc., in which a large number of unit panels are interconnected and combined.

In addition, the pressure inside the tank that is received on the side wall surface is divided by the tension rod to each of the side wall unit panels, so the pressure resistance of the assembled tank as a whole is equal to the pressure resistance of the number of unit panels. is also extremely preferable.

Furthermore, a flanged comb bushing is inserted between the tension rod and the unit panel, and the tip of the rubber bushing is made to bulge out due to the expanded diameter part, so the tension rod can be attached to extremely high watertightness. I can do it.

The watertight structure between the tension rod and the side wall of the unit panel is robust, and the work can be done simply from outside the tank, making it simple and advantageous in that water leakage accidents can be quickly dealt with.
