Abstract
Provided is an X-beam structure including: a plurality of beams extending in X-axis, Y-axis, and Z-axis directions and formed in a lattice pattern and a plurality of cross intersections at which an X-axis beam, a Y-axis beam, and a Z-axis beam meet one another, wherein in the X-beam structure in which a cross section of each beam has the geometry of a right-angled X, and the beam intersections are formed with one continuous beam and the two other joining beams are attached and welded onto the continuous beam.

An X-beam structure, comprising:
- a plurality of beams extending in X-axis, Y-axis, and Z-axis directions and formed in a lattice shape and a plurality of cross intersections 130 at which an X-axis beam, a Y-axis beam, and a Z-axis beam meet one another,
- wherein a cross section of each beam has a right-angled X shape,
- the cross intersections 130 are provided with continuous beams 110 onto which discontinuous beams 120 are attached or welded to the continuous beams 110, and
- the attached beams 120 have protrusions 121 in an angular shape formed at ends thereof and central portions of the protrusions 121 are provided with cut-outs 122 into which are consistent with the cross-sectional shape of the continuous beams 110.
