Abstract

Provided is a pressure tank having a lattice structure, including: a tank body that has a high-pressure fluid accommodated therein and is manufactured to have a prismatic shape; and cell structures that are disposed in the prismatic tank body, are manufactured in a lattice form, arrive from one side wall of the tank body to the other side wall thereof facing it, and are orthogonally arranged regularly.

First claim

What is claimed is:

1 . A pressure tank having a lattice structure, comprising:
a tank body that has a high-pressure fluid accommodated therein and is manufactured to have a prismatic shape; and cell structures that are disposed in the tank body, are manufactured in a lattice form, arrive from one side wall of the tank body to the other side wall thereof facing it, and are orthogonally arranged regularly.

2 . The pressure tank of claim 1 , wherein the cell structures include beam surface structures having flat cell walls that arrive from one side wall of the tank body to the other side wall thereof facing it and are orthogonally arranged regularly to intersect with each other and cell beams that are positioned at a point at which the cell walls intersect each other.

3 . The pressure tank of claim 2 , wherein the cell walls are provided with quadrangular cell wall holes of which the corners are rounded.

4 . The pressure tank of claim 3 , further comprising: surface stiffening members that contact top surfaces or bottom surfaces of the cell walls and are orthogonally arranged regularly at boundary surfaces of the cell wall holes to intersect with each other, and
the surface stiffening members are manufactured to have girders with flanges.

5 . The pressure tank of claim 2 , wherein the cell beams are manufactured as branching type cell beams,
the branching type cell beams include beams that extend in a three-dimensional orthogonal coordinate system (X, Y, and Z) structure.

6 . The pressure tank of claim 5 , wherein the cell beams are manufactured as circular cell beams each having circular sections, diamond?shaped cell beams each having diamond-shaped sections and corners of the diamond-shaped cell beams contact the cell walls, or
X cell beams each having “X” shaped cross sections and side portions of the X cell beams contact the cell walls.

7 . The pressure tank of claim 1 , wherein the tank body includes an inner wall contacting the cell structures and an outer wall positioned at a predetermined distance from the inner wall.

8 . The pressure tank of claim 7 , wherein at least one of an inner side of the inner wall, an outer side of the inner wall, an inner side of the outer wall, and an outer side of the outer wall is provided with the wall stiffening member having a lattice form,
the wall stiffening member is manufactured to be a girder with flanges and has an upper surface joined to the inner wall or the outer wall.

9 . The pressure tank of claim 7 , wherein a plurality of girders having a plate shape are disposed between the inner wall and the outer wall, the girders contacting the outer side of the inner wall to correspond to portions at which the cell structures contact the inner wall and the other sides thereof contacting the inner side of the outer wall.

10 . The pressure tank of claim 7 , wherein the plurality of girders with flanges are disposed between the inner wall and the outer wall, the top surfaces of the girders contact the outer side of the inner wall to correspond to a portion at which the cell structures contact the inner wall and flanges of the girders are welded to the plurality of outer walls.

11 . The pressure tank of claim 7 , further comprising: gas sensors sensing gas between the inner wall and the outer wall.

12 . The pressure tank of claim 7 , wherein it is constructed by previously manufacturing structures having one wall surface of the inner wall and the outer wall or a combination of a plurality of wall surfaces thereof.

13 . The pressure tank of claim 7 , wherein it is structurally stiffened and has improved heat insulating performance by filling concrete or heat insulating materials between the inner wall and the outer wall.
