Description

[Detailed Description of the Invention] The present invention relates to a reinforcing member for a storage tank for attaching a reinforcing bolt such as a tension rod inside the storage tank.

A storage tank such as a water tank has a wall surface formed by connecting a plurality of panels to each other, and since the strength of the connecting portion of this wall surface is low, it is necessary to attach a tension rod or the like to reinforce the wall surface.

1 and 2 show a cross joint reinforcement structure for a water tank in which four unit panels 10 are connected to each other by peripheral joints 12, and as shown in FIG. A tension rod 14 is passed through near the corner, and a nut 15 is screwed into the penetration part of the tension rod 14 outside the water tank.
Furthermore, a nut 18 is screwed into the tip after the plate 16 is inserted. Therefore, in this reinforced structure, each tension rod 14 is located at the center of the cross joint 10A.
Since they are equally spaced around the circumference, they each receive equal tension to support the water pressure and limit the bulge of the panel 10.

Figure 3 shows a reinforcing structure used for small-height, low-pressure aquariums, with two tension rods 1
4 is fixed to the unit panel 10 by a nut 18. In this case, the unit panel 10 to which the tension rod 14 is not attached is likely to shift due to water pressure (in the direction of arrow A), and the joint portion 12 will bulge out of the water tank due to rotational force (in the direction of arrow B) due to the earthquake load. I will do it.

For this reason, conventionally, despite the low water pressure, four tension rods are used to create the same structure as shown in FIG. 1, and the tension of each tension rod is equalized, which requires a larger number of tension rods than necessary.

The present invention takes the above-mentioned facts into account, and aims to provide a reinforcing member for a storage tank that can always provide balanced reinforcement at the panel joining joint regardless of the size of the storage tank.

The reinforcing member for a storage tank according to the present invention uses a mounting through hole to abut and fix a mounting board to the cross joint of a plurality of unit panels that constitute a storage tank, and from the part of the board corresponding to the cross joint. A female thread is carved into the upright socket, and a reinforcing bolt such as a tension rod is screwed into the female thread to eliminate unbalance at the panel joint.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a water tank using reinforcing members 20 and 22 according to the first embodiment of the present invention.

This water tank has a joint part 12 on the periphery of the rectangular plate.
Unit panels 10, each of which is erected at right angles, are joined to each other via a joint portion 12 to form a wall and a bottom. In this embodiment, unit panels 10 are connected in two stages, upper and lower, to form a wall, and a ceiling to which unit panels 10 are similarly connected is attached to the top.

The reinforcing member 20 is adapted to have a tension rod 14 as a reinforcing bolt attached thereto.
A socket 26 is connected to the center of a rectangular mounting board 24 shown in FIG. 6 at right angles to this board.
A female thread 28 for screwing the tension rod 14 is cut into the tip of the socket 26.

Further, in the rectangular mounting board 24, mounting holes 30 are generally formed in a square arrangement at equal intervals (dimension L) with the socket 26 at the center. These through holes 30 have axes that are parallel to the female threads 28, and the mounting bolts 3 are inserted as shown in FIG.
2 is applied and fixed to the unit panel 10. It is preferable to interpose a packing 33 between the substrate 24 and the unit panel 10.

After the mounting bolts 32 are inserted into through holes drilled in the corners of the four unit panels 10, a nut 34 is screwed from the tip, and after the tip passes through the plate 16, a nut 35 is screwed into the bolt. are combined. By passing the mounting bolts 32 through the corners of each unit panel 10 in this manner, the axes of the rectangular mounting board 24 and the socket 26 are centered at the cross joint where the corners of the four unit panels 10 are joined to each other. will be placed. Note that the plate 16 applies the tightening force of the nut 35 to the joint portion 12 to suppress the expansion of the joint portion 12.

As shown in FIG. 7, the reinforcing member 22 has a rectangular base plate 24 and a socket 26 similar to the reinforcing member 20, and the rectangular base plate 24 has a through hole 30 for attachment. The axis of the socket 26 is not perpendicular to the rectangular substrate 24, but at a predetermined angle (in this embodiment,
45°), and the female thread 28 is adapted to be screwed into the male thread formed at both ends of a diagonal place 36 as a reinforcing bolt shown in FIG. However, like the reinforcing member 20, the axis of the diagonal brace 36 is directed toward the center of the cross joint of the four unit panels.

Attachment of the reinforcing member according to this embodiment configured as described above will be explained. The reinforcing member 20 is attached by screwing the female threads 28 to both ends of the tension rod 14 in advance.

At this point, the mounting bolts 32 are applied to the through holes 30 of the rectangular mounting board 24 to fix the rectangular board 24 to the joint portion of the four unit panels 10. This fixation is the fifth
As shown in the figure, attach the nut 34 to the mounting bolt 32,
By applying the plate 16 and the nut 18, the rectangular substrate 24 is reliably and strongly attached to the unit panel 10.
It can be fixed to. Before attaching the rectangular substrate 24 to the unit panel 10 with the mounting bolts 32, the rectangular substrate 24 can be rotated relative to the tension rod 14 to finely adjust the amount of screw engagement with the tension rod and the tension of the tension rod. That is, the tension of the tension rod 14 is applied to the through hole 3 of the rectangular substrate 24.
0 is squarely arranged, fine adjustments can be made every quarter turn of the rectangular substrate 24, and even if there is no fine adjustment means such as a turnbuckle in the middle of the tension rod 14, the tension of the tension rod can be finely adjusted. be able to.

In this way, the rectangular substrate 24 is securely connected to the unit panel 1.
Since the axis of the tension rod is placed at the center of the cross joint of the four unit panels 10, an equal load is applied to the four unit panels 10 by the tension rod 14, and either A one-sided condition in which tension is concentrated and acts on the unit panel will not occur.

In addition, when changing the degree of reinforcement due to changes in the size and shape of the water tank, use the tension rod 14.
This can be easily handled by changing the thickness of the . Therefore, even when the degree of reinforcement is changed, unbalanced loads will not act on the joints of the unit panels, unlike in the past.

Similar to the reinforcing member 20, the reinforcing member 22 is attached to the unit panel 1 using four mounting bolts 32 as shown in FIG.
0, and the unbalanced load can be similarly eliminated by spanning the diagonal brace 36. However, in this case, unlike the tension rod 14, the rectangular substrate 24
To finely adjust the amount of screw engagement with the socket 26
is not provided perpendicularly to the rectangular substrate 24,
The adjustment of the amount of screw engagement between the rectangular substrate 24 and the diagonal brace 36 is limited to each rotation of the rectangular substrate 24 .

Next, FIG. 8 shows a reinforcing member 38 used in a second embodiment of the present invention. This reinforcing member 3
8 differs from the previous embodiment only in that the socket 26 is provided integrally with the rectangular substrate 24,
The same effects as the reinforcing member 20 of the embodiment described above can be obtained. Furthermore, if the axis of the female screw 28 or the axis of the integrally provided socket 26 is inclined with respect to the vertical line of the board 24, a reinforcing member for attaching the diagonal brace can be obtained.

Next, FIG. 9 shows a reinforcing member 40 according to a third embodiment of the present invention.

In this reinforcing member 40, the mounting board is the socket 4.
4 U-shaped plates 46 connected in the radial direction from 4
Each of these U-shaped plates 46 has a mounting through hole 30 formed near its tip.

Therefore, the reinforcing member 40 in this embodiment is lighter and stronger than the reinforcing members in the previous embodiments. Even in this embodiment, it is easy to change the axis of the female thread 28 to an inclined brace reinforcing member.

Next, FIG. 10 shows a reinforcing member 50 according to a fourth embodiment of the present invention, in which a rectangular substrate 24 is bent from its center to form an L-shape on both sides. Therefore, the axes of two of the four mounting through holes 30 and the other two are perpendicular to each other.

The socket 26, one end of which is welded to the bent portion of the rectangular substrate 24, has its axis located on the bisector of both sides of the rectangular substrate 24, that is, at an angle of 45° with both sides. .

Reinforcing ribs 52 are fixed between the vicinity of the tip of the socket 26 and both sides of the rectangular substrate 24, respectively.

FIG. 11 shows two diagonal braces 3 using two reinforcing members 50 and two reinforcing members 22, respectively.
A side view with 6 installed is shown. Here, the reinforcing members 50 are each fixed to a corner of the water tank and support one end of the diagonal brace 36. Therefore, the same effects as those of the embodiments described above can be obtained, and this embodiment has a structure suitable for reinforcing a narrow aquarium.

As explained above, in the storage tank reinforcing member according to the present invention, the socket into which the reinforcing bolt is screwed is provided upright from the part corresponding to the cross joint of the mounting board, and the mounting board has four square mounting through holes. Since it is mounted in contact with the cross joint of the unit panel, it has an excellent effect of being able to reinforce the storage tank without applying an unbalanced load even when the degree of reinforcement of the storage tank is changed.
