FIG. 1 is an exploded perspective view of a part of an oil barrier according to an embodiment of the present invention. The oil barrier 1 is composed of a rectangular border 2 and a bottom 3 surrounded by the border 2. The boundary part 2 includes a plurality of chevron-shaped legs 5 having inclined legs 4, a top support 7 which is removably connected to the tops 6 of the plurality of legs 5 and the legs 4 on the inner peripheral side, respectively; It has a side support 8 and a plate-shaped body 9 disposed on the inner peripheral side of the side support 8. The bottom portion 3 has a sufficient area to install a storage tank (not shown).

The legs 5 may have a chevron shape in which both legs 4 have symmetrical inclinations as shown in the figure, but they may also be formed in such a way that at least one leg 4 is inclined and the other leg 4 is vertical. . In such a case, the inclined leg portions are arranged so as to be located on the inner circumferential side of the boundary portion 2. Alternatively, the shape may be similar to a trapezoid shape in which the top portion 6 of the chevron is flattened.

As the top support 7 and the side support 8, for example, a rigid metal pipe or rod can be used.

These supports are removably attached to the top portion 6 or the leg portion 4 of the leg body 5 at a plurality of locations in the axial direction via hooks rO provided on each leg body 5, respectively. On the other hand, the top 6 of each leg 5
Or the legs 4 are thereby interconnected and integrated. In the illustrated example, legs 5 are integrally connected to each side of the border 2. The side support 8 is connected to the leg 5 as described later.
It also acts as a spacer between the plate-like body 9 and the leg body 5, which are arranged on the inner peripheral side of the plate body 9.

As the latching tool 10, for example, one composed of a U-shaped support accommodating portion and latching bolt nuts provided near both ends thereof can be used.

However, in order to make the connection easier, it is also possible to use only a U-shaped support accommodating part that opens upward, without using bolts, etc. In that case, the support is simply supported from above. Just drop it into the body storage section. Furthermore, the hook 10 may be provided on the support side.

In the illustrated example, in order to further strengthen the reinforcement of the legs 5 themselves and the mutual connection force, the lower portions of the legs 4 of each leg 5 are bridged by reinforcing members 11, and the reinforcing members 11 are bridged with each other. are removably connected by a reinforcing connector 12 and a hook 13, but these may be omitted depending on the case.

The plate-like body 9 can be constructed of a panel such as a steel plate or an FRP plate of an appropriate length, and a plurality of plate-like bodies 9 can be used in conjunction with each other depending on the length of the border 2. It has become. This plate-like body 9 has an inclined surface 14 bent at an obtuse angle in the middle thereof, and a flange portion 15 bent at an acute angle in the horizontal direction from the upper edge of the inclined surface 14. Slope 1
4 forms the base of the inner circumferential surface of the boundary portion 2, and a flange portion 15 is provided to support the upper part of the plate-like body 9 on the top support body 7. In addition, a plurality of locking pieces 16 are provided vertically downward from the tip of the flange portion 15 at appropriate intervals to prevent the flange portion 15 supported by the top support body 7 from coming off due to vibration or the like. There is. Furthermore, if necessary, the flange part 15 is provided with a plurality of wire insertion/grip holes 17 at appropriate intervals, so that the flange part 15 can be reliably supported by the top support member 7 by wires (not shown) or can be carried. This is an easy trick.

In addition to the above, the plate-shaped body 9 may be a punched metal formed by punching a steel plate, or a rigid net or lattice.

Each leg 5 is arranged so as to coincide with the boundary of each connected plate-like body 9. When supporting the flange portion 15 on the top support body 7, in order to avoid the flange portion 15 coming into contact with the hook 10 hooked on the top support body 7,
A notch 18 is provided at one end of the flange portion 15 . When the plate-like bodies 9 are connected through the cutout portion 18, a space is formed at the boundary between the flange portions 15 at the connection portion to avoid the upper portion of the hook 10.

In the example shown in FIG. 1, plate-shaped bodies 19 having a planar cross-section shape are placed at the four corners of the border 2 so as to be inserted between the ends of the plate-shaped bodies 9 on each side. This L-shaped plate member 19 is provided to more reliably and firmly form the four corners of the boundary portion 2, and may be omitted depending on the case. Furthermore, anchor means 20 is provided on the outer periphery of the boundary 2 of the oil barrier, if desired. This anchor means 20 more effectively prevents the boundary portion 2 from moving outward even when a large amount of oil spills into the oil barrier. The anchor means 20 can be constructed, for example, by erecting pipes 21 on a base at the outer periphery of the four corners of the border 2 as shown in the figure, and horizontally connecting the pipes 21 with pipes 22. The leg portion 4 on the outer peripheral side of each leg body 5 forming the boundary portion 2 is connected to this pipe 22.
