Description

[Detailed Description of the Invention] The present invention relates to a storage tank bottom attachment structure for attaching the bottom of a water storage tank or the like to a pedestal.

The water tank must be securely attached to the pedestal so that it will not fall off the pedestal or impact will not occur between it and the pedestal when an external force such as an earthquake is applied.

For this reason, conventionally, a mounting structure has been adopted in which a mounting bolt is passed vertically through a horizontal mounting portion of an H-beam used as a frame and a bottom plate of a water tank.

However, in this mounting structure, it is necessary to form a coaxial through hole with a vertical axis between the water tank bottom plate and the H-shaped steel horizontal mounting part, and it is necessary to separately drill through holes in the water tank bottom plate and the H-shaped steel horizontal mounting part. In the case of installation, the mounting bolts must be inserted and screwed together while aligning these through holes, making the assembly work extremely complicated.

The present invention takes the above-mentioned facts into account, and aims to provide a storage tank bottom mounting structure that does not require the provision of coaxial through-holes between the storage tank bottom and the pedestal, and which is easy to assemble.

In the storage tank bottom mounting structure according to the present invention, an anchor is screwed into the male thread of a mounting bolt that is fixed to the bottom of the storage tank and protrudes from the bottom, and a mounting hole bored in a direction perpendicular to the axis of the anchor is connected to a bracket attached to the frame. By inserting an anchor pin into a mounting hole formed in the support plate, the bottom of the storage tank is fixed to the pedestal via the anchor and the bracket.

An embodiment in which the present invention is applied to the bottom of a water tank will be described below with reference to the drawings.

A first embodiment of the present invention shown in FIGS. 1 and 2 shows a structure in which the bottom of the water tank is formed of a plurality of unit panels 10. These unit panels 10
are rectangular plates made of iron or FRP (fiber-reinforced plastics), and the peripheral edges thereof are bent at right angles to form flange plates 12 that are parallel to each other. These flange plates 12 are mutually fixed to flange plates of adjacent unit panels to form a water storage tank bottom.

A side wall (not shown) stands up from around the bottom, and a ceiling wall (not shown) extends from the top of the side wall.
A storage space 16 surrounded on the bottom by spanning over
is formed.

The lower ends of the flange plates 12 of these unit panels 10 are placed on the horizontal mounting portion 18A of the H-shaped steel 18, which is a frame. This horizontal mounting part 18
A may be integrated with the H-shaped steel 18, or may be a separate member fixed thereto. These H-beams 18 are placed on a concrete pedestal 20 and fixed by nuts 24 screwed into stud bolts 22 planted in the concrete pedestal 20.

A pair of flange plates 12, which are joint parts of adjacent unit panels 10, are connected to a pair of brackets 126, 22.
6, it is fixed to the horizontal mounting portion 18A of the H-shaped steel 18. These brackets 126, 226 have the same shape, and as shown in FIG. 3, the base plate 28 and the upright plate 30 are connected at right angles to each other to form an L-shape. A plurality of mounting holes 32 are drilled in the substrate 28 and correspond to the mounting holes 34 of the H-beam horizontal mounting portion 18A.

Bolts 36 and nuts 38 are applied to these mounting holes 32 and 34 to attach the board 28 to the horizontal mounting portion 18.
Although it is designed to be fixed to A, the mounting hole 32,
Preferably, the holes 34 are shaped like elongated holes as shown in the figure, and their longitudinal directions intersect with each other at right angles to absorb dimensional errors during assembly.

On the other hand, a plurality of circular holes 40 are bored in the vertical plate 30, and after the mounting bolts 42 pass through the circular holes 40 and the flange plate 12 of the unit panel, the nuts 44 are inserted.
are screwed together, thereby fixing the flange plate 12 to the brackets 126, 226.

Further, each of these brackets 126 and 226 is provided with a plurality of supporting plates 46 (four in this embodiment) vertically parallel to each other so as to support at least the substrate 2.
8 and the standing board 30. Coaxial holes 48 are bored in these support plates 46, and these holes 48 are preferably elongated holes as shown.

As shown in FIG. 4, bolts 50, which are anchor pins, pass through these elongated holes 48, and nuts 52 are screwed into them.
0 serves to connect the reservoir bottom to the brackets 126, 226 via anchors 54 and 56.

In detail, after the bolt 56 vertically passes through the reinforcing plate 58 and the unit panel 10 from the storage space 16 side, a nut 60 is screwed into the male threaded portion, and the female thread 62 of the anchor 54 is further screwed into the male threaded end portion. are doing. A circular hole 65 (see FIG. 4) bored perpendicularly to the axis of the anchor 54 has an elongated hole 4.
8 is penetrated by a bolt 50.

Therefore, the head of the bolt 56 is fixed to the unit panel together with the nut 60 by holding the unit panel, and the anchor 54, which is threaded with the bolt 56, is connected to the support plate 46 by the bolt 50. As a result, unit panel 10 is connected to brackets 126, 226 via bolts 56, anchors 54, and bolts 50.

Here, the elongated hole 48 of the support plate 46 is perpendicular to the axial center of the anchor 54 and perpendicular to the axial center of the bolt 50. Therefore, the bracket 126,2
This facilitates the connection between the anchor 54 and the support plate 46 even when the relative assembly positions of the unit panel 26 and the unit panel 10 are shifted in the left-right direction in FIG.

A mounting plate 64 is erected on the reinforcing plate 58 in the storage space 16, and one end of the diagonal stay 66 is fixed thereto.The other end (not shown) of the diagonal stay 66 is fixed to the side wall of the storage tank and is connected to the side wall of the storage tank. It is reinforced between the bottom and the bottom.

In addition, in the illustrated example, a heat insulating cover 72 made of a heat insulating material 68 and an external force bar 70 is attached to the lower surface of the unit panel 10, but this heat insulating cover 72
A hole 74 for the bolt 56 to pass through is bored in the hole 74 . This hole 74 only needs to be a circular hole with a size equivalent to the outer diameter of the nut 60 or the anchor 54, so that it has very little influence on the heat insulation effect of the heat insulating cover.

In the mounting structure of this embodiment configured in this way, after fixing the H-beam 18 onto the concrete pedestal 20 and placing the water tank on the H-beam 18,
An anchor 54 that fixes the brackets 126, 226 to the H-shaped steel 18 and the flange plates 12, 14, penetrates the bolt 56 into the unit panel 10, screws the nut 60, and further screws the bolt 56 to the tip end side.
The assembling work is completed by adjusting the amount of screw engagement, matching the heights of the circular hole 65 and the elongated hole 48, and attaching the anchor 54 to the support plate 46 with the bolt 50. During this assembly, especially the brackets 126, 226 are attached to the elongated holes 32.
If the horizontal holes 34 intersecting the horizontal mounting portions 18A of the H-beams are bored, the brackets 126, 226 can be installed. Furthermore, if the anchor 54 is attached to the support plate 46 through the elongated hole 48, the unit panel 10, the brackets 126, 226, the H-beam 1
There is no need to drill coaxial through holes across the unit panel 10 and the bracket 126,
Even if the relative position with respect to 226 is not uniform, it can be easily assembled.

After assembly, the bottom of the water tank is securely attached to the H-beam 18, so the water tank is attached to the H-beam 18.
8 or collide with the H-section steel 18 due to vibrations such as earthquakes and be destroyed.

Also, in this way, the unit panel 10 is not connected to the frame with a single penetrating bolt, but is connected to the brackets 126, 226 via the anchor 54 and the bolt 56, respectively. Therefore, unlike the case where the bottom of the water tank is arranged horizontally as in this embodiment, there are cases where the bottom of the water tank is supported on the frame at a slight incline, or where the unit panel 10 is of a bent structure from the viewpoint of strength. Even when the axis of the bolt 56 to be fixed is not perpendicular, the bottom of the water tank can be reliably connected to and supported by the frame.

Next, FIG. 5 shows an anchor 154 according to a second embodiment of the present invention. This anchor 154
is perpendicular to the axis of the circular hole 65 and anchor 1
A notch 76 is bored in the axial direction of 54, and the support plate 46 is inserted into this notch 76.

Therefore, in this embodiment as well, the anchors 154 are connected to the support plate 46 by bolts 50, but unlike the previous embodiment, one support plate 46 is connected to one anchor 15.
It corresponds to 4.

As explained above, in the storage tank bottom mounting structure according to the present invention, an anchor is screwed onto a mounting bolt that passes through the storage tank bottom, and this anchor is connected to a bracket attached to a pedestal using an anchor pin, so that there is a gap between the storage tank bottom and the pedestal. There is no need to drill a coaxial through hole in the
This has the excellent effect of making assembly work easier.
