Description

  The present invention relates to a support member connecting jig for connecting and connecting support members provided with slits in multiple upper and lower stages, and a connecting method using the support member connecting jig.

  When installing display shelves in a store or the like, for example, as shown in the perspective view of the conventional display shelf shown in FIG. 22, each of the columns 101 made of wood or light iron stud material installed at appropriate intervals, respectively. A support member 102 made of channel steel or the like is fixed using a tap screw 120. The support member 102 is provided with slits 107 in multiple upper and lower stages, and locking hooks of the bracket 1 are inserted into the slits 107 to be locked and attached. A shelf board 104 is placed on the bracket 1. Further, a backboard 105 is set between the support members 102 as necessary. Various display shelves to be installed in such a store have been proposed as described in Patent Document 1.

  By the way, in the current store design, the ceiling height, which was conventionally 2 m to 3 m, has become as high as 4 m to 5 m. Moreover, the setting of the ceiling height varies from store to store and from building to building.

  Conventionally, as the support member, a member corresponding to the height to be installed has been prepared. However, as described above, in the store design for various ceiling heights, the lengths of the required support members are various. If support members of various lengths are prepared, there is a problem that the stock increases accordingly.

  In addition, it is difficult to prepare a support member having a length of 4 m to 5 m in terms of manufacturing equipment, and even if it can be manufactured, it is difficult to load it in normal logistics. And even if it can be shipped, it cannot be mounted on an elevator in the field, and carrying-in work is difficult.

  Therefore, at present, when there is a support member having a length of 3 m or more, it is divided into two support members of 2400 mm and 1200 mm before shipping, and they are fixed in contact with each other. In this way, any height can be accommodated by adding support members.

The leg portion 220 is provided with a bending slit 222 in the central portion, and the leg portion 220 is configured to bend in the width direction by the bending slit 222. The leg portion 220 is provided with a step portion 221 between the tip portion and the main body portion 20.

  When the attachment member 2 is inserted into the slit 107, the leg portion 220 is inserted into the slit 107 while being bent, and is fixed to the slit 107 at the step portion 221. After fixing the attachment member 2 to the slit 107, the support member 102 is fixed to the support column 101 using the tap screw 3 as in the first embodiment.

  Next, a method for connecting and connecting support members will be described with reference to FIGS. In this example, the connecting jig 5 is used to connect the two support members 102. In addition, although it can add even if it does not use the connection jig | tool 5, use of the connection jig | tool 5 improves workability | operativity.

As shown in FIG. 21, the connecting jig 5 includes a plurality of claw parts 53 inserted into the slit 107 and a claw bolt 51 having a claw part 52 at the tip. In this embodiment, six claw parts 53 are bent at a right angle from the main body part 54. Each claw portion 53 is formed in a size to be inserted into the slit 107, and the interval between the claw portions 53 and 53 is formed in accordance with the interval between the slits 107 and 107. In the claw bolt 51, a nut member 51a and a butterfly screw 51c are engaged with a screw 51b. The two claw bolts 51 with claws are respectively fitted into oblong slots 55 provided in the main body portion 54 so that the claw portions 52 protrude in the same direction as the claw portion 53 bent at a right angle from the main body portion 54. Is attached.

  First, as shown in FIG. 17, the support is fixed to the column 101 or the like using the tap screw 3 in the countersunk hole 112 with the small edge of the support member 102 where the slit 107 is notched up. At this time, when the countersink is lacking in the upper part, the attachment member 2 of the present invention is inserted into the slit 107 and fixed.

  Subsequently, the support 102 is turned upside down, and the claw portions 53 and 52 of the connection jig 5 are inserted into positions where the countersink 112 is avoided, and the connection jig 5 is fixed with the claw bolt screws 51. At this time, the claw 52 of the jig 5 is directed downward to fix the connecting jig 5.

  Thereafter, the support 102 attached with the connection jig 5 is abutted against the support 102 fixed to the support column, and the connection jig 5 is fixed to the support fixed to the support column with a claw bolt. Thereafter, the upper support member 102 is fixed to the column by screwing with the tap screw 3. At this time, when the countersink is lacking in the upper part, the attachment member 2 of the present invention is inserted into the slit 107 and fixed.

  Finally, as shown in FIG. 20, the claw bolt 51 is loosened and the connecting jig 5 is removed. In this manner, the support member 102 can be added and fixed to the support column.
