BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a tank mounting structure.

[0002]

2. Description of the Related Art FIG. 10 is a sectional view showing an example of a conventional gantry structure on which a tank is mounted. Reference numeral 1 denotes a panel-assembled tank that is currently frequently used. For example, a joint edge is provided on the periphery of a square pressure receiving surface having a size of 1 m × 1 m, and a plurality of unit body panels integrally formed of a synthetic resin such as FRP are used. , Bolts through the packing of the joint edges of the unit panels. They are connected by nuts, and the roof 2, the side wall 4, and the bottom wall 3 of the tank 1 are assembled and formed.

In the above-mentioned tank 1 for storing drinking water in particular, a plurality of rectangular parallelepiped cloth foundations 11 made of concrete are generally arranged on the slab 12 in order to facilitate inspection of the bottom wall 3. And a flat base 5 on which a steel beam is hung is provided on the upper surface of the cloth foundation 11,
The tank 1 was placed on the flat base 5.

[0004] The flat mount 5 is constructed by assembling a main beam and an auxiliary beam, which are usually made of shaped steel, in a cross-girder shape (not shown) so as to be orthogonal to and along the joining edge of the bottom wall panel 10, and the entire bottom wall of the tank 1. I try to support. And it is fixed to the cloth foundation 11 by the foundation bolt 8 to prevent the displacement. Note that the flat base 5 has a steel structure and is usually manufactured in a factory.

[0005] On the other hand, the cloth foundation 11 is designed and constructed so that, in order to secure strength during an earthquake, the internal reinforcing bars 13a are generally connected to the reinforcing bars 13 of the slab 12 of a building or the like so as to be integrated integrally. ing.

FIG. 11 is a sectional view showing an example of a conventional gantry structure on which a tank is mounted. Reference numeral 15 denotes a standing stand having a large height. The standing stand 15 joins the gusset plates 16 and 16a to the main beam of the flat stand 5 and uses a plurality of gusset plates 16 and 16a with angle iron 7l as the main beam. A plurality of pedestals 17 are formed by orthogonally attaching the pedestals 17.
The structure is such that the angle is connected by 7 m of reinforcing angle steel that extends diagonally.

[0007]

[Problem to be solved by the invention] However, FIG.
The cloth foundation 11 shown in FIG.
3a and the reinforcing bars 13 inside the slab 12 had to be connected, and concrete had to be integrally formed. For this reason, there is a problem that material costs and labor such as formwork and reinforcing bars with concrete are expensive and expensive. In addition, since there is no gap between the cloth base 11 and the flat gantry 5, it is impossible to reach inside the flat gantry 5 from the outside. For this reason, when the bolt 26 for fastening the bottom wall panel 10 and the side wall panel 25 is fastened, there is a problem that the operation of fastening the bolt 26 becomes complicated and requires a lot of time.

The gantry 15 shown in FIG. 11 has gusset plates 16, 16 a for mounting a column base 17.
There is a problem that the design and manufacture of the device are required and the cost becomes high.

The present invention has been made in view of the above problems, and has as its object to provide an inexpensive tank gantry structure that can be easily operated in a short time.

[0010]

The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 4 corresponding to the embodiment. A gantry for a tank comprising a flat gantry in which beams and auxiliary beams are combined in a girder form, and a gantry base installed at a plurality of locations between the flat gantry and the ground or a slab and connected to the flat gantry and the slab at the same height. In the structure, the shape steel is connected to form a column base unit consisting of a hexahedron, and a plurality of the column base units are
Technical measures are taken in which blocks fixed to each other are formed, a gantry foundation is formed by the plurality of blocks, and the gantry foundation is fixed between the flat gantry and the slab.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing an embodiment of a gantry structure of a tank according to the present invention, and FIG. 2 is a perspective view showing a combination block of a column base unit in FIG.

In FIG. 1, reference numeral 5 denotes a flat base for mounting a panel-assembled tank (not shown). The flat base is composed of main beams 5a, 5b, 5c made of a U-shaped cross section and a U-shaped cross section. An auxiliary beam 6 made of steel is combined in a girder shape along the lower surface of the upright joining edge of the bottom wall panel of the panel-assembled tank.

In FIG. 2, reference numeral 14 denotes a column base unit serving as a base of the flat base 5;
Is formed in a hexahedron such that the flat surfaces of the angle irons 7, 7a and 7b are orthogonal to each other, and a hole 28 for bolt penetration is provided at a predetermined position on each flat surface. The pedestal unit 14 is fixed in a longitudinal direction by bolts or welding to form a block, three blocks are arranged in parallel at intervals, and the pedestal unit 14 and the flat base 5 are fixed to the gantry. Fastened by bolts 9.

FIG. 3 is a perspective view of a column base unit showing another embodiment of the present invention.
Has the same shape as the column base unit 14, but is different in that all of the angle irons 7c, 7d, and 7e, which are constituent members, are provided with a plurality of bolt holes 28. With the above configuration, the bolt connection column base units 18 can be connected by bolts in any direction.

FIG. 4 is a perspective view of a column base unit showing another embodiment of the present invention. Reference numeral 20 denotes angle irons 7f, 7g, 7
h is a brace column base unit having the same shape as the column base unit 14 but connecting and fixing opposite corners on the same plane with a brace 19 to improve torsional strength.

FIG. 5 is a longitudinal sectional view of the tank with the column base unit when the tank is installed on the gantry structure shown in FIG.
In this case, the lower part of the column base unit 14 is fixed to the foundation bolt 8.

FIG. 6 shows the column base unit 14 and the column base unit 20 with braces, and the column base units 14 are connected and fixed in a three-tier stack, and the flat base 5 and the tank 1 are installed thereon. It is sectional drawing of the tank with a column base unit in the case of having done.

FIG. 7 is a sectional view of the column base unit 21 with a door. The column base unit with door 21 has a hinge 27 attached to an angle iron 7k constituting a large column base unit, connects the door 22 via the hinge 27, and further connects the side plates 23, 23, 23a to the left, right and rear surfaces. Mounting bolt hole 24
And is fixed by bolts.

FIG. 8 is a sectional view of a tank with a column base unit when the column base unit 21 with a door shown in FIG. 7 is attached. A pump,
By installing a machine such as a switchboard, necessary equipment can be operated efficiently.

FIG. 9 is a sectional view of a tank with a column base unit when the strength of the slab 12 is low, for example. In this case, a flat base 5 having the same or similar structure as the flat base 5 is placed on the slab 12.
By laying d, the force applied to the slab 12 can be dispersed.

[0021]

According to the present invention, a gap is formed on the lower surface side of the flat stand, and a hand can be put inside the flat stand from the gap. Therefore, when assembling the tank, bolting between the side wall and the bottom wall of the tank and bolting between the tank and the gantry can be efficiently performed in a short time.
Not only is the fabric foundation unnecessary, but also the pedestal units and flat gantry pre-fabricated at the factory can be directly installed on the slab, so the place where the flat gantry is installed changes depending on the circumstances of the building and surroundings. In this case, it can be easily dealt with and is extremely economical. Furthermore, when manufacturing a stand with a large height, a plurality of column base units stacked and combined in two or more stages are arranged and fixed on a slab, and a flat base is installed and fastened on the upper surface of the column base unit. By doing so, it is possible to easily make, and it is possible to shorten the manufacturing time and reduce the cost.
