DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, a metal laminate shelf 1 comprises a plurality of lower shelves 2 spaced apart from one another. The top ends of the columns 3 of these lower shelves 2 are connected to a plurality of lower shelves 2 by a common beam 4,
These beams 4 extend perpendicular to the front face M of the lower shelf 2. In this embodiment, the beam 4 is formed from an H-beam. H
The mold steel beam 4 has an upper flange portion 4a and a lower flange portion 4b. A flange formed at the top end of the shelf 3 is brought into contact with the bottom surface of the lower flange portion 4b of the H-shaped steel beam 4,
Here, the H-shaped steel beam 4 and the shelf 3 are fastened. On the other hand, on the upper flange portion 4a of the H-beam 4
Are arranged side by side.
An upper shelf 6 is arranged on the floor plate 5, thus forming the laminated shelf 1.

Referring to FIGS. 3 (A) and 3 (B), one longitudinal side of each floor plate 5 has a long side wall 7a which is bent at one longitudinal side and extends downward from a flat portion 5a of the floor plate 5.
A receiving groove 7 that opens upward is formed by a bottom wall 7b extending outward from the floor plate 5 from the long side wall 7a and a short side wall 7c extending upward from the bottom wall 7b. On the other hand, on the other side in the longitudinal direction of each floor plate 5, an L-shaped projection is formed by a side wall 8a that is bent at the other side in the longitudinal direction and extends downward from the flat portion 5, and a bottom wall 8b that extends inward from the side wall 8a. 8 are formed. The floor boards 5 are connected to each other by receiving the L-shaped projections 8 of the respective floor boards 5 in the receiving grooves 7 of the adjacent floor boards 5. At this time, the side wall 8a of the L-shaped projection 8 extends along the long side wall 7a of the receiving groove 7, and the bottom wall 8b of the L-shaped projection 8 extends along the bottom wall 7b of the receiving groove 7. When the pair of floor plates 5 are connected in this manner, a gap 9 is formed between the top end surface of the short side wall 7c of the receiving groove 7 and the bottom surface of the flat portion 5a of the floor plate 5 facing this. Note that, for example, a small protrusion for preventing slippage may be formed on the flat portion 5a of the floor plate 5, or a through hole may be formed.

The rigidity of the floor plate 5 can be increased by forming the receiving groove 7 and the L-shaped projection 8 in the floor plate 5 as described above. Further, the floor plate 5 can be easily connected by simply receiving the L-shaped projection 8 in the receiving groove 7. Furthermore, an electric cable can be accommodated in the receiving groove 7, for example, and in this case, the electric cable can be hidden when the floor plate 5 is looked up from below.

The stacking shelf 1 further includes a metal fastener 10 for fastening a pair of floor plates 5 adjacent to each other and simultaneously fastening the floor plates 5 and the beams 4 to each other. Referring to FIG. 4, the fastener 10 includes a main body 11, a bolt 12, and a nut 13. The main body 11 formed by bending a flat plate has a rectangular bottom wall 11a, long and short side walls 11b and 11c extending upward from two opposing sides of the four sides of the bottom wall 11a, and the remaining four sides of the bottom wall. A small side wall 11d extending upward from two sides. In the top end face of the long side wall 11b, a floor plate concave groove 14 capable of receiving the bottom of the receiving groove 7 of the floor material 5 is formed. On the other hand, a contact surface 15 that can contact the bottom surface of the upper flange 4a of the H-beam is formed in the top end surface of the short side wall 11c. In the example shown in FIG. 4, the contact surface 15 is formed from the top end surfaces of two protrusions slightly projecting from the top end surface of the short side wall 11c. However, without forming such a projection, the contact surface 15 may be formed from the top end surface of the short side wall 11c.

Referring to FIG. 4, a gap is formed between the short side wall 11c and the pair of small side walls 11d, and a beam groove 16 is formed in each gap. Further, a through hole 17 is formed in the bottom wall 11a. The through-hole 17 is arranged substantially at the center between the pair of small side walls 11d, but is arranged slightly closer to the short side wall 11c than to the long side wall 11b.

The bolt 12 has a hook-shaped head, and a tip portion 12a extends downward. On the other hand, the end portion 12b of the bolt 12 having the thread formed extends below the main body 11 through the through hole 17 of the main body 11, and is screwed with the nut 13. Next, this embodiment will be described in detail with reference to FIGS. As shown in FIGS. 5A and 5B, the bottom of the receiving groove 7 of the floor plate 5 is received in the floor plate concave groove 14 of the main body 11 of the fastener 10. On the other hand, the contact surface 15 is brought into contact with the bottom surface of the upper flange portion 4a of the H-shaped steel beam 4, and thus the upper flange portion 4a is sandwiched between the contact surface 15 and the receiving groove 7. At this time, the bolt 12 extends upward through the through hole 17 of the main body 11, extends downward in the receiving groove 7 through the gap 9, and the tip 12 a of the bolt is formed on the bottom wall 8 b of the L-shaped projection 8. It is in contact with the top surface 8ba. Further, the tip of the upper flange portion 4a is located at the center of the main body 11 rather than the tip 12a of the bolt.

When the nut 13 is tightened in this state, the distance between the bolt tip 12a and the groove 14 for the floor plate is reduced, and the pair of floor plates 5 are fixed to each other between the bolt tip 12a and the groove 14 for the floor plate. Is done. At the same time, the distance between the bolt tip 12a and the contact surface 15 is reduced, and the floor plate 5 and the H-shaped steel beam 4 are fastened to each other between the bolt tip 12a and the contact surface 15.

As described above, the floor plates 5 and the floor plate 5 and the H-shaped steel beam 4 can be fastened to each other simply by tightening the nut 13. In this case, since the nut 13 is located below the bottom wall 11a of the main body 11, the work can be easily performed. Further, the floor plate 5 can be easily removed when the laminated shelf 1 is disassembled, and the floor plate 5 can be reused because no trace of welding remains on the floor plate 5.

As apparent from FIG. 5B, the height of the short side wall 11c of the main body 11 up to the contact surface 15 is determined by the height between the long side wall 11b and the groove 14 for the floor plate. This corresponds to a value obtained by subtracting the thickness of 4a. Next, another embodiment will be described. This embodiment differs from the above-described embodiment in that the beam is formed from a C-beam 4.

Referring to FIG. 6, a flange 18 is attached to the top of the shelf 3 of the lower shelf 2 and the C-shaped steel beam 4 is bolted to the flange 18, for example. A floor plate 5 is arranged on the top wall 4c of the C-shaped steel beam 4. The opening 4d of the C-shaped steel beam 4 is defined by a downward facing side wall 4e and an upward facing side wall 4f, and the opening 4d is directed in the horizontal direction. An electric cable or the like can be accommodated in the internal space 4g of the C-shaped steel beam 4 as well as the receiving groove 7 of the floor panel 5.

In this embodiment, similarly to the above-described embodiment,
The bottom of the receiving groove 7 of the floor plate 5 is received in the floor plate concave groove 14 of the main body 11 of the fastener 10. On the other hand, the short side wall 11c
Is inserted into the internal space 4g of the C-shaped steel beam 4 and C
The bottom end of the downward side wall 4e of the mold steel beam 4 is received in the beam concave groove 16 of the main body 11, and thus the downward side wall 4e is sandwiched between the internal wall surface of the beam concave groove 16 and the receiving groove 7.

When the nut 13 is tightened in this state, the distance between the bolt tip 12a and the groove 14 for the floor plate is reduced, and the pair of floor plates 5 are fixed to each other between the bolt tip 12a and the groove 14 for the floor plate. Is done. At the same time, the distance between the bolt tip 12a and the groove 16 for the beam is reduced, and the floor plate 5 and the C-shaped steel beam 4 are fastened to each other between the bolt tip 12a and the groove 16 for the beam.

As described above, the fastening device 10 can be applied to the case where the beam 4 is an H-shaped steel beam and a case where the beam 4 is a C-shaped steel beam. Therefore, it is not necessary to prepare the fastening device according to the shape of the beam. .

[0020]

According to the present invention, the floor plates and the floor plate and the beam can be fastened easily and at low cost. Moreover, the floorboard can be easily removed, and the floorboard after removal can be reused. Further, a single fastener can be applied to both H-beams and C-beams.
