PROBLEM TO BE SOLVED: To provide a high rigidity beam configured to be capable of promoting the improvement of flexural strength while avoiding increase in the amount of work and burden relating to transportation, assembly, disassembly and the like, and also capable of preventing waste of an occupied space.SOLUTION: The high rigidity beam includes a square cylindrical three-dimensional beam 2 and a pair of flat beams 3 holding the three-dimensional beam 2. The three-dimensional beam 2 includes: four long pipe materials 7 arranged quadrilaterally and in parallel with each other; connection materials 8 connecting perpendicularly a plurality of longitudinal positions between the long pipe materials 7; and diagonal members 9 connecting the long pipe materials 7 of both sides between the adjacent connection materials 8 in a brace manner. The flat beam 3 includes: two long pipe materials 7 provided in parallel with each other; the connection materials 8 connecting perpendicularly a plurality of longitudinal positions between the long pipe materials 7; and diagonal members 9 connecting the long pipe materials 7 of both sides between the adjacent connection materials 8 in a brace manner. The high rigidity beam is installed and used by setting the annexing direction of the beams 2, 3 and the longitudinal direction of the beams 2, 3 along a horizontal direction. |
