Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an iron panel for the construction of side walls in assembled water tanks.

[Prior art and its problems]

Iron panels have excellent pressure resistance and fire resistance, and are mainly used for constructing high heads and large assembled aquariums, and the number of panels required for construction is large, and each panel is smaller than an FRP panel. Due to their high weight, it is preferable to inventory the required number at once or transport them using a forklift to improve work efficiency. There are many requests for this regardless of which iron panel.

Conventionally, there is a panel disclosed in Japanese Utility Model Application Laid-Open No. 111510/1983 that allows stacking in multiple stages without causing the load to collapse.

In this prior art, as shown in FIG. 14, an engaging surface 101 is integrally molded to protrude from the outer surface of a peripheral joining flange 100 by the thickness of the joining flange 100. Joining flange 1 at the periphery of the upper panel on the mating surface 101
This is a panel for ceiling wall construction that can be stacked by engaging the 00 inner surfaces.

By the way, in the iron panel for the side wall, connecting pieces 200 such as stays and braces are fixed to the corners of the inner surface of the pressure-receiving surface directly behind the joint flange 201 on the water tank side in two protruding places, so the connecting pieces 200 It was generally believed that the stacking was not possible due to the obstruction of the
figure).

When imparting a stacking function to this iron panel for configuring the side wall, two connecting pieces 200 are fixed at positions displaced toward the center of the inner surface of the pressure-receiving surface on the aquarium side, and further from the outside, that is, from the protruding position of the joining flange 201. At the development stage, an attempt was made to form an engagement surface 101 similar to that in the prior art on the inner surface of the pressure receiving surface on the aquarium side, which is slightly inside. (Figure 16).

However, in this prototype example, the following problems occurred.

As a result of the connection piece 200 being fixed to a displaced position on the inner surface of the pressure-receiving surface on the aquarium side, the stays and braces that were originally supposed to reinforce the cross-shaped joint between the panels are installed at a position away from the cross-shaped joint. Therefore, the reinforcing effect of the cross-shaped joints between the panels becomes weak, and it is necessary to provide another reinforcing mechanism.

Since there are only two connecting pieces 200, the direction in which the stays and braces are installed is restricted, and the installed stays and braces have no directional flexibility, making it difficult to obtain the desired internal reinforcement effect.

The iron panel having the engaging surface 101 must be molded using a new mold, which increases equipment costs.

[Technical issues]

The technical problem of the present invention is to arrange the load collapse prevention pieces (engaging surfaces) at positions that allow the panels to be stacked, that is, at four corners, and to attach the load collapse prevention pieces to retaining rods such as stays and braces. The goal is to provide connectivity functionality.

[Technical means]

The technical means of the present invention are as follows.

Load collapse prevention protrusions lower than the protrusion height of the joint flange are integrally fixed to the four corners of the inner surface of the pressure receiving surface on the water tank side, which is slightly inside the protruding position of the joint flange, and the load collapse prevention protrusions are attached to retaining rods, etc. It is formed in the shape of a connecting piece.

[Effect]

The effects of the technical means of the present invention are as follows.

The four corners of the cargo collapse prevention pieces are housed in the space between the outer surface of the pressure receiving surface of the upper stacked panel and the joint flange in a position close to the inner surface of the joint flange, and the inner surface of the joint flange of the upper panel is The panel is prevented from sliding by coming into contact with the cargo collapse prevention piece.

The stays and braces can be erected in a desired direction by using the load collapse prevention pieces at the four corners as connection pieces.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the figure, 2A is the main body of the iron panel for the side wall 2B with a joint flange 4 protruding in the same direction as the central bulge 3, and 1A is a ceiling wall with a joint flange 4 protruding in the opposite direction to the central bulge 3. , shows the iron panel main body for the bottom wall 1B, each of which is formed by press working.

The bulging portion 3 is shaped to have a radial or desired pressure-resistant structure, and is attached to the iron panel main body 2A for the side wall.
A cargo collapse prevention piece 1 formed in the shape of a connecting piece 1' is fixed to four corners of the back surface of the flat surface 2a of the pressure receiving surface 2 portion separated by the bulging portion 3 of .

The cargo collapse prevention piece 1 is integrally fixed to the four corners of the water tank side inner surface of the pressure-receiving surface 2 slightly inside the protruding position of the joint flange 4 in the main body 2A of the iron panel for the side wall, and its height is the same as that of the joint flange 4. It is slightly lower than the height.

In addition, holes 5 for connection with the adjacent iron panel bodies 1A, 1A, 2A, and 2A are opened at the same intervals in the joint flange 4 after press working, and the load collapse prevention piece 1 is similarly connected to the retaining rod C. Connecting holes 6 such as the above are pre-drilled.

Then, the entire surface of the iron panel main body 2A for the side walls having the cargo collapse prevention piece 1 and the entire surface of the iron panel main body 1A for the ceiling and bottom walls are coated with a synthetic resin such as nylon or epoxy resin to serve as the iron panel A.

Needless to say, the water tank body B has a ceiling wall formed by connecting the joint flanges 4, 4 of the iron panel main body 1A to a side peripheral wall 3B, which is formed by connecting the joint flanges 4, 4 of the iron panel main body 2A. , are formed by fitting and connecting the bottom wall 1B from above and below in a closed manner.

Next, the cargo collapse prevention piece 1 will be referred to as a connecting piece 1', and the connection of the retaining rod C based on the actual shape of the connecting piece 1' and the actual shape of the retaining rod C will be described in detail.

In Figure 3, a so-called cross-shaped connecting piece 1a, which is made by crossing two flat plates in a cross shape, is used as a connecting piece 1', and an arm rod 1C as a retaining rod C is secured to each connecting hole 6 with bolts 6, and the adjacent connecting pieces 1a are used as connecting pieces 1'. The arm rod 1C is installed across the side wall 2B, the bottom wall 1B, or the opposing side wall 2B.
The connection is fixed.

Fig. 4 shows an L-shaped angle member 7 used as the retaining rod C, and consideration has been given to increasing the strength of the retaining rod C itself.

Figures 5 and 6 show a pair of adjacent connecting pieces 1' used to connect the retaining rods C.
The figure shows horizontal mounting pieces 8 extending from both ends of the main body 7a of the L-shaped angle member 7 to form a retaining rod C, and the mounting pieces 8 being used as horizontal pieces 1'' of the adjacent connecting pieces 1' facing each other. Fig. 6 shows how the parallel bent pieces 10a of the retaining rod C, which is formed by integrally providing the U-shaped connecting piece 10 at the tip of the rod-shaped body 9, are aligned with the relative positions of the adjacent connecting pieces 1'. It is connected to the vertical piece 1.

As for the actual shape of the connection piece 1', there are various types depending on the purpose and function of its use, as shown in FIGS. 7 to 13. It is not limited to the shape of piece 1'.

[Effect of idea]

Since the present invention is constructed as described above, it has the following advantages.

The load collapse prevention pieces fixed to the four corners of the inner surface on the water tank side of the pressure-receiving surface have the function of connecting with restraints such as stays and braces, so the connection piece 2 can be placed at a position away from the cross-shaped joint between the panels. Conventional shortcomings include the fact that the reinforcing effect of the cross-shaped joints between panels is weak, as in the prototype example where panels are forced to stick together, and the installation direction of the stays and braces is specified, making it impossible to erect the stays and braces in any direction. Iron panels for side walls can be provided at low cost.

Thus, the intended purpose can be achieved.
