Description

[Detailed description of the invention] The present invention relates to a tension rod mounting structure in a storage tank, in which a tension rod that is hung between opposing walls in a storage tank such as an aquarium to prevent deformation between the walls is attached to the support at right angles to the support in the storage tank. .

Generally, inside a storage tank such as a water tank, multiple columns are installed vertically to support the load from the ceiling plate, and multiple tension rods are installed horizontally to prevent earthquakes. It is designed to prevent deformation between the side walls during lateral vibrations such as

These tension rods are prevented from being bent by having their intermediate portions supported by support rods via support rods.

If the support rod attached to the column to support the tension rod is designed to simply place the middle part of the tension rod, there is a risk that the middle part of the tension rod may fall off from the support rod during vibrations such as an earthquake. There is. For this reason, a support rod has conventionally been used in which a portion of the tension rod support rod is provided with a passage portion through which the tension rod can move only in its axial direction, that is, only in a direction perpendicular to the column.

However, this support rod interferes with a socket that coaxially connects a plurality of tension rods, thereby hindering the longitudinal movement of the tension rods during assembly work. For this reason, workers who enter the storage tank during assembly are forced to perform complicated and long hours of work in order to assemble a plurality of tension rods.

Taking the above facts into account, the present invention allows multiple tension rods to be easily assembled, and after assembly, the middle part of the tension rod can be placed in a storage tank without falling off from the support rod even if subjected to vibration. The purpose is to obtain a tension rod mounting structure.

The in-storage tank tension rod mounting structure according to the present invention is provided with a tension rod penetrating portion by inverting and bending a protruding portion of a support rod rotatably attached to a support column.
The protruding tip is sized so that when the axis of the tension rod penetrating part becomes approximately parallel to the column axis due to rotation of the support rod, there will be a gap larger than the outer diameter of the tension rod between it and the outer periphery of the column. The tension rod is designed so that it can be easily inserted into the tension rod penetration part, and the distance between the tip of the support rod and the outer circumference of the support rod is smaller than the tension rod outer diameter when the axis of the tension rod penetration part is approximately perpendicular to the column axis. After insertion, the support rod is rotated approximately 90 degrees and both ends of the tension rod are attached to opposing parts in the storage tank, and the structure is such that the middle part of the tension rod does not slip out from the tension rod support rod.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which the mounting structure of the present invention is applied to a panel aquarium 10. The panel aquarium 10 includes a plurality of rectangular unit panels 12 connected to each other at their peripheral edges to form a hexahedral panel aquarium 10.

A water supply pipe 1 is located near the upper end of this panel water tank 10.
4 are connected to each other so that water can be supplied into the tank, and a drain pipe (not shown) is connected to the bottom to drain the water stored in the tank. Further, if more water than necessary is stored in the storage tank, it is drained through an overflow pipe 16.

A plurality of pipe supports 18 are installed inside the water tank 10 to support the load of the ceiling plate.

As shown in detail in FIGS. 2 and 3, the upper ends of these columns 18 are formed with flat plate portions 20 that receive crushing forces from both sides in the direction orthogonal to the axis. This flat plate part 20 is clamped at one end of a flat connecting plate 22, and this connecting plate 22 and flat plate part 20 are connected by bolts 24.
It is fixed by.

A notch 26 is formed in the center of the other end of the connecting plate 22 to avoid the flange 28 of the unit panel 12, and both ends of the notch 26 are fixed to the flange 28 with bolts 30.

In this way, the upper end of the support column 18 can be easily fixed to the ceiling plate by simply interposing the connection plate 22, and the support column 18 will not fall off even during vibrations such as an earthquake. Note that the axis of the support 18 is the unit panel 12.
The flat plate part 20 is connected to the support 1 in order to match the joints of the
It is provided at a position eccentric from the axis of 8.

Next, as shown in FIG. 4, a through hole 32 is bored in the middle of the support 18 in a direction perpendicular to the axis of the support 18, and a support rod 34 passes through it. Both ends of the support rod 34 are bent in a substantially U-shape, and a tension rod penetration portion 36 is formed inside the bent portion.

Here, a large distance is provided between the bent end portion 38 of the support rod 34 and the outer periphery of the support column 18 in the position shown in FIG. 4, but in the position shown in FIGS. At this position, the distance between the outer circumference of the support column 18 and the outer circumference of the support column 18 is reduced.

That is, in the state shown in FIG. 4, the axis of the tension rod penetrating portion 36 is the axis of the inserted tension rod 40, and is approximately parallel to the axis of the support column 18. In this case, there is a tension rod 4 between the tip of the support rod 34 and the outer periphery of the column 18.
Therefore, in this state, as shown in FIG.
can be easily inserted into the

However, in the state shown in FIG. 6, that is, when the support rod 3 rotates until the axis of the tension rod penetrating portion 36 becomes substantially orthogonal to the axis of the support column 18, the support rod 3
4 and the outer periphery of the strut 18 is reduced so that the tension rod 40 cannot escape from the tension rod penetration 36.

Therefore, to explain the procedure for assembling the tension rod in this embodiment, as shown in FIGS. Insert the middle part of the tension rod 40. Now rotate the tension rod 40 about 90 degrees counterclockwise in the figure 1 about the support rod 34.
When rotated once, the distance between the tip of the support rod 34 and the outer periphery of the column 18 is reduced as shown in FIG. 6, so that it becomes impossible for the tension rod 40 to escape through this distance.

Thereafter, both ends of the tension rod 40 are made to protrude from the side wall of the panel water tank, and nuts are screwed together from the outside of the water tank, thereby completing the installation of the tension rod 40 as shown in FIG.

The tension rod 40 is composed of two rods 40A and 40B whose one ends are connected to each other by a socket 42 having an internal thread. Therefore, the short tension rods 40A, 40B can be easily inserted into the tension rod 40 from the manhole 44, and the socket 42 can be used to form one tension rod 40 in the water tank, and the socket 42 can be used as the tension rod 40A, 40B.
By rotating it relative to 40B, the overall length of the tension rod 40 can be changed, making assembly extremely easy.

As described above, the tension rod mounting structure in this embodiment is such that the tension rod 40 is rotated approximately 90 degrees and then both ends are attached to the panel water tank, so that the tension rod 40 can be moved largely in the axial direction within the support rod 34 and the tension rod penetration portion 36. Therefore, there is no need for the socket 42 to interfere with the tension rod support rod 36.

Even after installation, the tension rod 40 maintains the dimension between the side walls of the panel water tank 10 at a predetermined length as shown in FIG.
Even if this vibration occurs, the tension rod 40 will not fall off from the tension rod penetrating portion 36, and since the rotation of the support rod 34 is prevented by the tension rod 40, Under no circumstances will the intermediate portion of the tension rod 40 fall out of the tension rod penetration portion 36 and become deflected.

Next, FIG. 7 shows a support rod 34 according to a second embodiment of the present invention. The tip end 46 of the support rod 34 is cut at a predetermined angle with respect to the axis of the support rod 34, and in the state shown in FIG. It forms a passage space. However, when rotated 90 degrees about the axis, the tip 46 can be brought closer to the outer periphery of the support column 18 than in the previous embodiment, and the tension rod can be held more securely.

Next, FIG. 8 shows another example of attaching the support column 18 to the ceiling.

In this embodiment, a connection plate similar to the connection plate 22 shown in FIG. 2 is used, but unlike in FIG. 2, the flat plate portion 20 formed at the upper end of the column 18 is arranged on the axis of the column. . Therefore, this flat plate portion 20 is suitable for attaching the small-diameter support column 18 to a ceiling plate.

As explained above, in the storage tank tension rod mounting structure according to the present invention, the support rod having the tension rod penetrating portion at the bent portion is rotatably attached to the column, so that the tension rod can be easily inserted with the tension rod support rod approximately parallel to the column. If the tension rod is rotated approximately 90 degrees and attached to the panel aquarium, the distance between the tip of the support rod and the outer circumference of the support column will be reduced. Therefore, multiple tension rods can be easily and quickly installed in a panel water tank, and after installation, the middle part of the tension rod can be reliably supported to the support column even during vibrations such as an earthquake, and the tension rod can be prevented from deflecting. have an effect.
