2. Description of the Related Art Conventionally, as this kind of column material for a shelf frame, for example, one described in Japanese Patent Application Laid-Open No. 8-196354 is known. This pillar material is provided on the outer periphery of the resin-coated steel pipe, extending in the longitudinal direction thereof, with a shelf receiving locking portion having a U-shaped cross section composed of two opposing strip-shaped sides and a bottom side connecting them. , One side is joined with the coating resin and molded integrally with it to make a pillar material.
A large number of locking grooves extending from the other side to the bottom side are formed at required intervals at right angles to the opening edge of the other side. In addition, the shelf frame using the above-mentioned pillar material is configured such that two pillar materials are formed such that the opening portions of the shelf receiving locking portions are opposed to each other, and the locking grooves forming a pair at the front and rear are horizontal straight lines. Then, a side frame is formed by connecting the resin-coated steel pipe and the resin joint in a rectangular shape, and a pair of side frames at a required interval are connected in a frame shape by the resin-coated steel pipe and the resin joint, and the front and rear column members are latched to the shelves. A strip-shaped support portion having a thickness that can be inserted into the locking groove, a required width, and a length approximately equal to the distance between the front and rear pillars in each of the locking grooves and the opening in the portion; And a vertical portion having a thickness that can be inserted into the opening portions of the front and rear shelf receiving locking portions in an L-shape.

[0003]

However, in the conventional column material for a shelf frame, a large number of locking grooves of the shelf receiving locking portion for locking the shelf receiving are perpendicular to the opening edge of the other side, that is, It is formed at right angles to the axis of the resin-coated steel pipe, and since each shelf receiver of the shelf frame using this column material is horizontal, a shelf board placed on each shelf receiver,
There is a problem that it becomes more inconvenient to take in and out articles to be placed such as containers or trays at higher places. Further, in order to form the locking groove in the shelf receiving locking portion of the pillar material, if the locking groove is perpendicular to the axis of the resin-coated steel pipe, there is no problem, but the locking groove is the axis of the resin-coated steel pipe. If it is inclined at a required angle with respect to a straight line perpendicular to, the column material is horizontally sandwiched between the vice so that the other side of the shelf receiving locking part is on the top, and grooved by a saw blade Alternatively, the column material must be mounted on the table of the horizontal milling machine at the required angle of inclination so that the other side of the shelf receiving latch is vertical, and grooving must be performed. As a result, there is a problem that mass production becomes difficult and cost increases. Therefore, the present invention provides a column material capable of easily manufacturing a shelf frame that allows articles to be easily taken in and out even at high altitudes, a shelf frame using the same, and a shelf frame column material processing apparatus.
