Description

[Detailed description of the invention] <Industrial field of application> The invention is an internally reinforced type assembled water tank in which the tank walls are internally reinforced by installing stays between adjacent tank walls with the corners of the tank in between. Regarding.

<Prior Art> Conventionally, as a device for reinforcing the tank wall of an assembled water tank to maintain the tank in its regular shape, there is a method disclosed in, for example, Japanese Utility Model Application No. 54-85412.

In this structure, in a tank formed by connecting a large number of unit plates, a support is provided with both ends bent to the same side so that the bent portion is a flat surface, and the flat surfaces of the support are connected to unit plates that are orthogonal to each other. By abutting and fixing the tank against the flat plate of the tank, the tank is reinforced from the inside.

However, in this case, when constructing a support between adjacent tank walls with a corner in the tank in between, a bolt insertion hole is drilled in the tank wall for each support, and the flat surfaces at both ends of the support are installed. The pillars had to be brought into contact and fixed by tightening, and the work of constructing the pillars inside the tank was very time-consuming.

Therefore, as disclosed in Japanese Utility Model Application Publication No. 54-49613, a vertical wall is provided on the periphery of the front side of the small flat plate and perpendicular thereto, and two or more threaded rods are installed upright on the back side of the small flat plate. A stay fixing block, which is integrally fixed, is attached to each tank wall adjacent to each other across the inner corner of the tank, and the stay is attached across the vertical wall of the block and other vertical walls located on the same plane. There is one in which both ends of the aquarium are tightened and a stay is installed between each tank wall to reinforce the aquarium.

However, since both ends of each stay are attached to the vertical wall provided on the stay fixing block, there is no need to drill a bolt insertion hole in the tank wall for each stay and install it. However, since the end of each stay is fastened to the vertical wall of the block with bolts, etc., the connection between the two is weak, and the bolts may loosen or come off after long-term use. There was a fear that this would happen. Furthermore, since the structure of such a stay fixing block is complicated, it has problems such as a rise in cost.

<Problems to be Solved by the Invention> The problems to be solved by the invention are to have a simple yet robust structure, and to internally reinforce the assembled aquarium without increasing costs.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to reduce the distance between adjacent tank walls across the inner corner of an aquarium constructed by connecting a large number of unit plates. A main stay is formed by welding and fixing the corner portions of the L-shaped angles to both ends of a support column that is constructed across the main stay. At the same time, the main stay is erected and fixed, and the other plane of the L-shaped angle vertically raised from each tank wall is used as the mounting surface of the auxiliary stay, on the same plane of the mounting surface and across the corner of the tank. The auxiliary stay is constructed and fixed across the mounting surfaces of other auxiliary stays located on adjacent tank walls.

<Example> An example of the present invention will be described based on the drawings.
The assembled water tank A consists of a 1 m square unit plate 1 with an upright edge 1a around the periphery and a bulging part 1c in the center leaving a flat pressure-receiving plane part 1b, or a 1 m square unit plate 1 with two opposing sides 1.
A side wall A ₁ and a bottom wall are formed by connecting a number of half unit plates 1, each of which is 0.5 m and the other two opposing sides are 0.5 m.
A ₂ is a well-known size and shape in which the ceiling wall (shown in the figure) is assembled into a cube or rectangular shape, and the side wall A ₁ , the bottom wall A ₂ and the side wall A are adjacent to each other across the inner corner of the tank. ₁ , A ₁ Comrade main stay B
and the auxiliary stay C are installed and fixed, and each tank wall, especially the side wall _A , is reinforced from the inside to hold it in a regular shape.

The main stay B is composed of both L-shaped angles b ₁ and b ₂ and a support column b ₃ mounted across both the L-shaped angles b ₁ and b ₂ .

L-shaped angles b ₁ and b ₂ are units that connect and form L-shaped members made by bending angle members or strip plates at right angles in the length direction to the side wall A ₁ and bottom wall A ₂ of the assembled water tank A, respectively. It is cut to a predetermined length that straddles the joining line 2 between the plates 1 and extends between the corner pressure-receiving plane parts 1b of both unit plates 1, and one surface of the plane connected at right angles is used as the wall mounting surface 3, The other plane serves as a mounting surface 4 for the auxiliary stay C.

Parallel bolt insertion holes 5 are formed in both lengthwise parts of the wall mounting surface 3 and the mounting surface 4 for the auxiliary stay C, respectively.

When the support column b ₃ is constructed by extending an L-shaped steel material to a desired length, for example, between the corner pressure-receiving flat parts 1b of the 1 m square unit plate 1, the two sides facing the 1 m square unit plate 1 should be 1 m long. and the other opposing two sides are
Since the length will naturally differ depending on the installation inclination angle when it is installed across the corner pressure receiving flat part 1b of the so-called half unit plate 1 of 0.5 m, it is cut to a desired length corresponding to these, the end of it
The L-shaped angles are integrally welded and fixed inside the corners at the longitudinal centers of the L-shaped angles b ₁ and b ₂ .
The main stay B is formed by attaching b ₁ and b ₂ to both ends of the support column b ₃ in a T-shape (FIG. 4).

In addition, in order to correspond to the installation inclination angle, support column b ₃
Even if the fixing angles to the L-shaped angle b ₁ and b ₂ at both ends are changed, the wall mounting surface 3 of the L-shaped angle b ₁ and the mounting surface 4 for the auxiliary stay C are different from the auxiliary stay C of the other L-shaped angle b _2. The wall mounting surface 4 and the wall mounting surface 3 are always parallel to each other (Figures 5 and 6).

The auxiliary stay C is formed by cutting an L-shaped steel material to a desired length and drilling bolt connection holes 6 at both ends of the L-shaped steel material, similarly to the support column _b3 .

Therefore, in this embodiment, the joining line 2 between the unit plates 1 connecting and forming the side wall A ₁ and the bottom wall A ₂ of the assembled water tank A is
The wall mounting surfaces 3, ₃ of the L-shaped angles b ₁ , b ₂ at both ends of the support column b 3 are placed in contact with the pressure receiving plane portion 1b at both corners that straddles the support column b 3, respectively, and both bolts installed in parallel on the wall mounting surfaces 3, 3 Insert the bolt through hole 7 drilled in the pressure receiving plane part 1b from the insertion hole 5, project the lining bolt 8 out of the tank, tighten it with the nut 9, and attach both the L-shaped angles _b1 and _b2, respectively. Then, the main stay B is installed and fixed across the side wall A ₁ and the bottom wall A ₂ and between the side walls A ₁ and A ₁ .

Then, the auxiliary stay C is attached to the L-shaped angles b ₁ and b ₁ , which are vertically erected from the two side walls A ₁ and A ₁ that are adjacent to each other with the inner corner of the tank in between, and are located on a straight line on the same plane. Auxiliary stay C between surfaces 4 and 4
Then, the lining bolts 10 are inserted from the bolt connection holes 6 at both ends of the auxiliary stay C into the bolt insertion holes 5 of the mounting surfaces 4, 4, and tightened with nuts 11 to attach the auxiliary stay C. erected and fixed between the side walls A ₁ and A ₁ (Figures 1 and 2). Furthermore, mounting surfaces 4, 4 for the auxiliary stays C of the L-shaped angles b ₁ and b ₂ attached and fixed to the side wall A ₁ and the bottom wall A ₂
Tighten the auxiliary stay C between them in the same manner as described above, and erect and fix the auxiliary stay C across the side wall A ₁ and the bottom wall A ₂ , and fix and reinforce the four sides of the side wall A ₁ of the assembled water tank A within the tank. This prevents bulging deformation of the four sides of the side wall _A1 and holds it in a regular shape.

<Functions of the invention> Since the present invention is constructed as described above, it has the following effects.

The auxiliary stay is constructed and fixed between the auxiliary stay attachment surfaces of the main stay, which has L-shaped angles integrally welded to both ends of the support column, so this main stay, which has a simple structure and is strong, can handle the main stress. It functions as a body to prevent bulging deformation of the tank wall due to internal pressure.

Therefore, even if the auxiliary stay is bolted to the auxiliary stay mounting surface, the bulging deformation force due to the internal pressure of the tank wall will not be concentrated on the bolt, and the stress applied to the bolt by the auxiliary stay mounting surface will be reduced. Therefore, a simple yet robust internal reinforcement structure can be achieved.

Since the structure of the main stay is extremely simple, consisting of a support column and an L-shaped angle, it does not cause a rise in cost and is economically advantageous.

Thus, the intended purpose can be achieved.
