Description

[Detailed Description of the Invention] [Prior Art] A panel assembly type tank has a unit panel integrally formed of synthetic resin such as FRP with a joint edge around the periphery of a rectangular pressure receiving surface measuring, for example, 1 ^m x 1 m. The tank bottom, side walls, and ceiling are assembled by connecting multiple joint edges with bolts and nuts through packing.

By the way, as the capacity of panel-assembled tanks increases, there is also the problem of installation locations, so there is a method to increase the volume by 1.5 to 2 times by connecting the tanks in two layers in the height direction of the unit panels. Inside, multiple rod-shaped stays were installed vertically and horizontally between opposing side walls due to water pressure.
However, there are drawbacks such as the need to produce a large number of unit panels in order to manufacture one panel-assembled tank, and the on-site assembly requiring many bolt joints, which is complicated work.

Therefore, in order to eliminate the above-mentioned drawbacks, we improved the molding machine and synthetic resin, as well as improved the molding machine as shown in Figure 1.
The height of the unit panels is made 1.5 times to about twice the height of the conventional one and connected horizontally in one stage to form a panel assembly type tank, and the side wall panels 2 are made as shown in FIGS. 9 to 11. A side wall reinforcement 7' perpendicular to the joint edge is fixed with bolts and nuts with the outer surface of the reinforcement 7' protruding from the joint edge of the side wall panel 2, and the upper part of the reinforcement 7' is placed above the tank 1. A roof stay 12 is stretched and fixed between the side walls above the water surface, with both ends passing through the side wall panel 2, the side wall reinforcement 7', and the upper contact plate 5' fixed to the reinforcement 7'. In addition, in the lower part of the reinforcement 7', two sides perpendicular to the reinforcement 7' are connected to a pedestal 11 having a substantially U-shaped cross section, which is extended by welding or the like with a fastening plate 14 on the upper side below the side wall panel 2. Plaquet 1 with approximately triangular side surfaces and a reinforcing plate provided approximately in the center between the two sides.
It was fixed with bolts and nuts with 3 in between.

[Problem that the invention seeks to solve]

However, since the roof stay 12 is provided in the upper part of the side wall panel 2 of the reinforcement structure of the panel assembly type tank described above, there are the following drawbacks.

1. Roof stays are installed vertically and horizontally near the roof panel in the upper part of the tank, so when cleaning the ceiling surface inside the tank, the roof stays get in the way and dirt cannot be completely removed, resulting in unsanitary conditions. be.

2. Since the roof stay requires at least a length longer than the distance between the opposing side walls of the tank, it becomes expensive, and when the distance between the side walls is long, the assembly work of the roof stay becomes complicated.

3. When drinking water is stored in a tank, the roof stay corrodes due to the removal of residual chlorine for disinfection.

In addition, at the bottom of the side wall panel 2, a pedestal 11
Since the fastening plate 14 provided on the side wall panel 2 and the side wall reinforcement 7' fixed to the side wall panel 2 are fixed via the bracket 13, there are the following drawbacks.

1. The bracket protrudes far outward from the side wall panel, which is dangerous as it gets in the way when inspecting the tank.

2. Since the fastening plates are welded on-site, the frame is deformed by heat, which can cause water leakage in panel-assembled tanks and is expensive.

The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a side wall reinforcement structure for a panel assembly type tank that is economical and easy to maintain, inspect, and assemble by simplifying the vertical reinforcement structure of the side wall panel. This is what I did.

[Means for solving problems]

The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 8 corresponding to the embodiments.
A plurality of unit panels provided with 6 are assembled by connecting the joint edges 16 to assemble the bottom, side walls, roof, etc., and side wall reinforcement 7 having an L-shaped cross section is attached to the vertically adjacent joint edges 16, 16 of the side wall panels 2. In a panel assembly type tank 1 which is provided facing each other and whose side wall height is one side of one unit panel, one side of the side wall reinforcement 7 is fixed so as to be flush with the joining edge surface of the side wall panel 2. At the same time, an upper abutting plate 5 of a metal plate is fixed to the upper surface of the upper end in the height direction of the side wall reinforcement 7, and a lower bent abutting plate 6, which is a metal plate having an L-shaped cross section, is fixed to the upper surface of the lower end. , a technical means is constructed in which the roof panel 3, the upper abutment plate 5, the lower bent abutment plate 6, and the frame 11 are fixed.

[Effect]

Then, the present invention uses the above-mentioned means to attach the side wall reinforcement to the joint edge of the assembled tank from the top to the bottom, fix the side wall reinforcement to the roof panel via the upper abutment plate to the upper part of the side wall reinforcement, and fix the side wall reinforcement to the roof panel at the lower part. It is fixed to the frame via a lower bent abutment plate.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

1 has an inclined edge around the periphery of a rectangular pressure-receiving surface and an upright edge by bending the tip thereof, and connects multiple unit panels made of synthetic resin such as FRP by connecting multiple inclined edges or upright edges. This is a panel assembly type aquarium with a bottom, side walls, and roof. and,
The height of the prefabricated aquarium 1 is such that one side wall panel 2 has a side length of, for example, 1 m x 1.5 m, and is stacked in a single layer on a pedestal. Reference numeral 7 denotes a side wall reinforcement made of steel and having an L-shaped cross section, one side of which is fastened to the intermediate adjacent upright joint edge 1 excluding the corner portions with a bolt/nut 9'. is located parallel to the side wall panel 2, on the same plane as the end surface of the side wall panel 2, and the other side is perpendicular to the side wall panel 2.

FIG. 8 shows another embodiment of FIG. 3, in which reinforcing materials are provided at the inner corner portions of the L-shaped downwardly bent abutment plate 6. FIG.

In addition, the present invention has the advantage that the L-shaped lower bending contact plate 6 does not protrude outward and is fastened to the side wall reinforcement 7 and the frame 11 with bolts and nuts, so that the installation area is smaller than that of the conventional method. be.

〔Effect of the invention〕

Since the present invention has the above-mentioned configuration, the roof stay is not required in the upper part of the side wall reinforcement, so the inner roof part of the panel assembly type tank can be cleaned easily, and the assembly work is also easy and it can be provided at a low cost. . In addition, at the bottom of the side wall reinforcement, the outward protrusion of the panel-assembled tank is the sum of the thickness of the lower bending abutment plate and the thickness of the bolt head, which may get in the way during inspection and cause injury. There will be no more dangerous inspections. Furthermore, since there is no need to weld the frame and the fastening plate on-site, the frame becomes less expensive, and the disadvantage of the frame deforming due to heat and causing water leakage in panel assembly tanks is eliminated.
