  Furthermore, a downward second load applying portion 11 is provided on the side wedge body 9 separately from the load applying portion 8. The load adding portion 11 is provided as necessary, and is shown by a solid line in FIGS. 5 and 7, but is shown by a one-dot chain line in the other drawings. In the embodiment, the load adding portion 11 is provided integrally with the load adding portion 8 and extends to the right side of the upper surface of the arm portion 8A or the mounting base 8C to the upper side of the side wedge body 9. A continuous member 11A made of an extended plate is provided, and a female screw hole 11B is formed vertically above the side wedge 9 of the continuous member 11A, and the female screw hole 11B is connected to the continuous member 11A. The male screw shaft 11C made of a bolt, which is a lifting member that can be lifted and lowered, and whose lower end 11D side can come into contact with the upper surface of the side wedge body 9, is screwed. The load applying portion 11 is not a screw connection, but may be a projection that is fixed to the connecting member 11A and can apply a load to the side wedge body 9.

Next, the operation of the above configuration will be described. The side wedge body 9 is integrated with the retaining means 10 in advance, and the left fitting member 4 and the right fitting member 5 are fitted to the fixed object 1 from the left and right. That is, the left end plate portion 4A and the right end plate portion 5A are respectively provided on the left and right end surface portions 1A and 1B, the left front plate portion 4B and the right front plate portion 5B are provided on the front plate portion 1C, and the rear plate portion 1D. The left fitting member 4 and the right fitting member 5 are fitted from the left and right sides of the fixed object 1 so that the left rear plate portion 4C and the right rear plate portion 5 are assigned. At this time, the locking portion 5E is moved in the width direction along the through hole 4G , and the locking portion 5E is set to either one so that the left fitting member 4 and the right fitting member 5 are loosely fitted to the fixed object 1. The length is adjusted in the left-right direction by being engaged with the engagement receiving portion 4F. At this time, the side wedge body 9 is held at a high position with respect to the right fitting member 5. That is, the shaft member 10B is kept at a high position of the through hole 10A. In this way, the fixed object 1 is externally fitted from the left and right directions by the left fitting member 4 and the right fitting member 5, and the side wedge body 9 is provided between the right end surface portion 1B and the right end plate portion 5A. Intervene.

Next, the front wedge body 6 is inserted into the front side guide path 5F, and the load applying portion 8 is attached. In this attachment, first, the attachment base 8C is placed in an upward state via the shaft 8B so as to facilitate the work. Then, the front wedge body 6 is inserted into the front guide path 5F so that the wedge front plate portion 6B is slidably brought into contact with the right front plate portion 5B. Thus, the front wedge body 6 is interposed between the front plate portion 1C and the right front plate portion 5B. The front wedge body 6 is positioned at a relatively high position so that the upper end of the front wedge body 6 is arranged at the upper end of the front plate portion 1 so as not to drop at the beginning of installation. Thereafter, the mounting base 8C can be held in the horizontal direction by rotating the mounting base 8C in the horizontal direction and engaging the stopper 8D with the right front plate portion 5B. In this state, the scaffolding plate 2 or the shelf plate is assembled to the fixture 3.

  When a load such as the scaffold plate 2 or the shelf board is applied to the front wedge body 6 in the assembled state, the rear end surface 6D of the front wedge body 6 is crimped to the front plate portion 1C of the fixed object 1 by the wedge action. Thus, the scaffolding plate 2 or the shelf plate can be fixed to the fixed object 1 via the fixture 3. If, for example, the thickness of the front plate portion 1C and the rear plate portion 1D is reduced, a gap is formed between the front wedge body 6 and the front plate portion 1C. However, the front wedge body 6 descends along the guide path 5F and retreats so that the front wedge body 6 abuts on the front plate portion 1C and loosens the fixture 3 to the fixed object 1 via the front wedge body 6. It can be fixed without.

  When a load such as the scaffolding plate 2 or the shelf plate is applied to the side wedge body 9, the wedge inner plate portion 9 </ b> B of the side wedge body 9 is crimped to the right end surface portion 1 </ b> B of the fixed object 1 by a wedge action and fixed object 1. The scaffolding plate 2 or the shelf plate can be fixed to the first through the fixing tool 3. In the unlikely event that the width between the left and right end face portions 1A and 1B becomes thin, a gap is formed between the side wedge body 9 and the right end face portion 1B. However, the side wedge body 9 descends along the side-side guide path 5G and advances inward, so that the side wedge body 9 abuts on the right end surface portion 1B, and the fixing bracket 3 is attached to the fixed object 1 via the side wedge body 9. Can be fixed without loosening.

  The load adding portion 11 is used as follows. First, the front wedge body 6 is inserted into the guide path 5F, the load application portion 8 is attached, and the stopper 8D is locked to the right front plate portion 5B, so that the attachment base 8C is held in the horizontal direction. The member 11A is disposed directly above the side wedge body 9. Then, the male screw shaft 11C is screwed into the female screw hole 11B, and the lower end 11D is brought into contact with the upper surface of the side wedge body 9. In this state, the scaffolding board 2 or the shelf board is assembled to the fixture 3.

Therefore, not only the front wedge body 6 but also the side wedge body 9 is loaded with the weight of the scaffold 2 and the weight of the article placed on the shelf via the load adding portion 8 and the load adding portion 11. It will be. For this reason, the thickness of the front plate portion 1C and the rear plate portion 1D is reduced, a gap is formed between the front wedge body 6 and the front plate portion 1C, and the width between the left and right end surface portions 1A and 1B is thin. In such a case, when a gap is formed between the side wedge body 9 and the right end surface portion 1B, the front wedge body 6 to which a load is applied by the load adding portion 8 extends along the front side guide path 5F. The front wedge body 6 comes into contact with the front plate portion 1C as it descends and retreats, and the side wedge body 9 loaded by the load adding portion 11 descends along the side guide path 5G and moves forward. The fixed metal fitting 3 can be fixed to the fixed object 1 via the front wedge body 6 and the side wedge body 9 without being loosened by coming into contact with the face plate portion 1C.

  As described above, in the above-described embodiment, the left and right fitting members 4 and 5 that are circumscribed by the left and right portions of the fixed object 1 and open toward the inner side in the left and right direction are substantially U-shaped. The wedge bodies 6 and 9 are provided inside the left and right fitting members 4 and 5, and the front side guide path 5 </ b> F that opens rearward is provided in front of the right fitting member 5. A front wedge body 6 is slidably provided on the side guide path 5F, a load applying portion 8 is provided on the front wedge body 6, and the right end plate portion 5A of the right fitting member 5 is opened toward the inner surface. The side guide path 5G is provided vertically and the side wedge body 9 is slidably provided on the side guide path 5G, so that the front wedge body 6 loosens the front-rear direction of the fixed object 1 and the fixture 3. Can be fixed without any looseness, and the lateral direction of the fixed object 1 and the fixing bracket 3 can be fixed from the side wedge body 9 without looseness.

  Further, since the load applying portion 8 is provided with a stopper 8D that can be locked to the right fitting member 5, the torque generated by the load of the load adding portion 8 can be resisted by the stopper 8D. 2 or a shelf board can be held reliably.

  Further, since the load applying portion 8 is rotatably connected to the front wedge body 6, the load adding portion 8 may be directed upward when the front wedge body 6 is inserted into the front guide path 5F. It becomes possible and workability can be improved.
