As described above, according to the rack frame structure of the present invention, in the vertical frame for partitioning the lattice structure of the rack, two oblique connections whose one ends are adjacent to each other and which are inclined in opposite directions to each other. Since the adjacent ends of the members are attached to the column material by a single fastener in a state where they are overlapped with each other, the ends of each diagonal connecting member are individually formed into the column material as in the related art. Compared with the case where the dedicated fitting is used, the number of rack components and the labor for assembling are reduced, and the weight and cost can be reduced.

According to the second aspect of the present invention, although the weight of the diagonal connecting member can be reduced and the strength can be increased by using the pipe, the thickness of the mounting end portion of the two-layered connecting member can be improved. The distance between the pair of left and right protruding plate portions can be reduced by reducing the thickness, and the thickness of the column member having the pair of right and left protruding plate portions can be suppressed. At this time, according to the configuration of the third aspect, it is possible to increase the strength of the flat mounting portion of the oblique connection member, and to easily form the flat mounting portion having a thickness approximately half the diameter of the pipe. Can be.

Further, according to the structure of the fourth aspect, the cross-sectional performance at the joint portion with the support member is smaller than that of the oblique connection member in which both ends of the pipe are simply flattened to form a flat mounting portion. Down can be minimized. In this case, according to the configuration described in claim 5, the compression in the axial direction of the mounting hole received at the time of mounting by the coupler deforms the flat mounting portion having a rectangular cross-sectional shape in section or the bending of the column material in accordance with the bending of the column material. It is possible to effectively prevent the flat mounting portion having a rectangular cross section from buckling and deforming into a parallelogram shape.

Further, according to the configuration of the sixth aspect, the plane area of the space occupied by two vertically adjacent diagonal connecting members can be reduced, and the thickness of the diagonal connecting members is particularly supplemented. At least, it is possible to eliminate or reduce the protrusion of the oblique connection member into the load storage space on both sides, and to prevent a reduction in the rack storage efficiency.
