| abstract |
A plurality of beams extending in the X-axis, Y-axis, and Z-axis directions of the present invention are formed in a lattice form and include a plurality of intersections where X-axis beams, Y-axis beams, and Z- The X-shaped beam structure having a right angle is characterized in that a main axis in which one beam is continuously formed and a sub-axis are coupled and welded to the main axis to form the intersection. In addition, the pressure tank having the X-shaped beam structure of the present invention further includes a tank main body having a prismatic shape and containing a high-pressure fluid therein, and the X-shaped beam structure is disposed inside the tank main body And reaches from the one side wall of the tank body to the other opposing side wall, and is regularly and orthogonally arranged. |
