Since the column shelf A has the same symmetrical shape on the left and right sides, the right side is omitted and only the left side is shown. 2 is an exploded view of a shelf support and a wrapping tool, which are the main parts of the present invention, and FIG. 3 shows an eccentric state of the shaft hole on the side surface of the bulging part of the shelf support. It is a side surface longitudinal cross-sectional view of the part.

The pillar shelf A is composed of a pillar 1, a shelf plate 2 in which a plurality of shelf bars 2 a are attached to the shelf receiver 3, and a winding tool 4 for fastening the shelf receiver 3 to the pillar 1. The pillar 1 is a so-called projecting pillar B which is erected by pressing the upper and lower ends of the pillar body against the floor surface and the ceiling surface, and is composed of the main pillar 1a of the hollow pipe and the adjustment pillar 1b inserted into the main pillar. The main pillar 1a is provided with an adjuster 1c at the lower end thereof for adjusting the tension and tension, and the adjustment pillar 1b is inserted at the upper end thereof via a fixture 1d. A fitting 1e is provided.

The shelf board 2 is composed of left and right shelf supports 3 and 3 and six shelf bars 2a inserted between the two shelf supports, and the left and right shelf supports 3 and 3 are symmetrical. The outer surface is flat and the inside is provided with six insertion holes 3a into which the ends of the shelves 2a are inserted. The shelves 2a form a U-shaped cross section 2b having a recess. The shelf rails 3 provided at the front and rear ends of the shelf support 3 are inserted with the concave surfaces facing each other, and the shelf rails 2a provided at the intermediate portion have the concave surfaces inserted downward. The shelf boards 2 are formed by arranging the upper surfaces of all the shelf bars 2a ... In parallel so as to be flush.

By arranging recesses from the upper surface to the rear surface of the bulging portion 3b formed by enlarging the rear end portion of the shelf support 3, the upper surface recessed portion 3d and the rear surface recessed portion 3e are provided to form the contact surface 3f. It is formed continuously. Further, the shaft hole 3c provided on the side surface of the bulging portion 3b is eccentrically set so that the distance 1 from the upper surface recess 3d side is smaller than the distance L from the rear surface recess 3e side as shown in FIG. ing. Then, both sides of the bulging portion 3b are clamped by both side pieces of the planar U-shaped wrapping tool 4, and the screw 4a is inserted into the shaft holes 3c and 4c and screwed by the nut 4b to support the shaft. ing.

Next, the work procedure for fastening the shelf 2 to the support 1 will be described. The space where the support shelf A is installed is determined, and the support 1 and the support 1 are projected at intervals equal to the length of the support 2. Set up by means. The winding tools 4 and 4 of the shelf supports 3 and 3 are removed, the shelf board 2 is set in the inverted posture (Fig. 4A), the upper surface recessed portion 3d of the bulging portion 3b is brought into contact with the column 1, and the shelf board After the tip of 2 is also brought into contact with the strut 1, the winding tool 4 is wound inward from the outer peripheral surface 1g of the strut 1, and the bulging portion 3b is sandwiched by both side pieces thereof, and the screw 4a and the nut 4b shaft are held.
