Description

  The present invention relates to a joining structure of members, and is applied to, for example, a joining portion between a building material and a horizontal material attached as a frame material to a pallet for carrying luggage or materials.

  As a pallet for carrying luggage and materials in a stock yard such as a warehouse or construction site, for example, a frame composed of a vertical material 21 and a horizontal material 22 is installed around the pallet main body 20 as shown in FIG. Pallets are known.

Moreover, as a junction part of the building material 21 and the horizontal material 22 in this case, as shown in FIG.3 (b), (c), for example in the side part of the building material 21, and the front-end | tip part of the horizontal material 22 Each of the protruding metal fittings 23 and the coupling metal 24 is abutted against each other, and the wedges 25 are inserted into the wedge holes 23a and 24a formed in both the coupling metal 23 and the metal fitting 24, respectively, so that they can be easily joined. Department is known.

  However, in such a joint structure, the wedge 25 is simply inserted into the wedge hole 23a of the connecting bracket 23 and the wedge hole 24a of the connecting bracket 24, so that the wedge 25 can easily fall off due to vibration or impact during transportation. There was a risk of it.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and provides a joining structure for members that can easily join members such as building materials and horizontal materials and does not easily come off. It is for the purpose.

The member joining structure according to claim 1 is a receiving metal fitting protruding from a side surface portion of one of the members to be joined, a connecting metal fitting protruding from the tip of the other member to be joined, A wedge for coupling the receiving metal and the connecting metal, and a loosening prevention plate separate from the connecting metal for fixing the wedge, the connecting metal being provided with an upper end flange projecting from the upper end side of the receiving metal and an intermediate flange and has a lower end flange projecting from the lower end side of the receiving metal, between the upper end flange and intermediate flange of the connecting fitting, there is interposed in a gap of the slack preventing plate in the vertical direction In addition, the upper end flange, the intermediate flange, the lower end flange, the slack preventing plate, and the wedge hole into which the wedge is inserted are formed continuously in the coupling metal.

The present invention particularly relates to a slack prevention plate in which a wedge is inserted into a wedge hole formed in an upper end flange and a lower end flange of a coupling metal, and a gap is provided between the upper end flange and the intermediate flange in the vertical direction. Since the wedge is fixed in the three wedge holes, the wedge is not easily loosened, so that the wedge is not dropped off by impact or vibration.

Note that by closing the sides of the slack preventing plate provided with a lip piece which rises vertically to the upper end flange side to the distal end portion of the intermediate flange, and a top end flange and intermediate flange and lip piece and U E blanking rectangular fitting And a slack prevention plate can be fitted in the fitting portion in advance.

  Further, if a plurality of slack prevention plates are interposed, the wedges are fixed by four or more wedge holes, so that the wedges can be more reliably inserted.

The present invention is particularly wedge is inserted into the wedge hole formed in the upper flange and the lower end flange of the connecting fitting, and that the top flange and a separate anti-loosening plates of the interposed allowed a connecting fitting between the intermediate flange Since it is inserted into the wedge hole and fixed at three locations , and the slack prevention plate is interposed with a gap in the vertical direction between the upper end flange and the intermediate flange of the connecting bracket, it can be easily removed by impact or vibration. There is no end to it.

  Therefore, the members such as the building material and the horizontal material can be easily joined to each other and can be connected so as not to be easily detached.

  1 and 2 show an example of a pallet used to carry luggage and materials in a warehouse or a stock yard of a construction site. In the drawings, building materials are provided at each corner portion of the pallet body 1 formed in a square plate shape. 2 are erected, and a horizontal material 3 is bridged horizontally between the building materials 2 and 2.

  Both the building material 2 and the horizontal material 3 are formed of steel pipes. The receiving metal 4 is attached to the side surface of the building material 2, and the connecting metal 5 is attached to the front end of the horizontal material 3. The receiving metal 4 and the connecting metal 5 are abutted with each other and are connected to each other by the wedge 6.

  The receiving metal fitting 4 is formed in a plane U shape, and has a wedge hole 4a that protrudes from the side surface portion of the building material 2 by welding its opening end side to the side surface portion of the building material 2 and penetrates in the vertical direction. Forming.

The connecting fitting 5 has an upper end flange 5a and an intermediate flange 5b that are provided in two steps on the upper end side of the receiving metal fitting 4 at a predetermined interval, and a lower end flange 5c that is provided on the lower side of the receiving metal fitting 4, Between the upper end flange 5a and the intermediate flange 5b, a clearance 9 is provided in the vertical direction, and a loosening prevention plate 7 separate from the connection fitting 5 is inserted.

  A lip piece 5d that rises substantially vertically toward the upper end flange 5a side is formed at the tip of the intermediate flange 5b. It can be preliminarily attached by being fitted into a rectangular fitting portion composed of the piece 5d and the web.

  Wedge holes 8a, 8b, 8c, 8d are formed in the upper end flange 5a, the intermediate flange 5b, the lower end flange 5c and the loosening prevention plate 7 of the coupling metal 5 so as to communicate with each other in the vertical direction, and the wedge holes 8a, 8b, 8c, 8d. Corresponding to the shape of the wedge 6, the diameter (width) is gradually different.

  That is, the width of the wedge hole 8a of the upper end flange 5a is the largest, and then gradually decreases in the order of the wedge hole 8b of the slack preventing plate 7, the wedge hole 8c of the intermediate flange 5b, and the wedge hole 8d of the lower end flange 5c. . And the wedge 6 is continuously inserted in the wedge hole 8a, 8b, 8c, 8d.

In such a configuration, the wedge 6 is inserted into the wedge holes 8a and 8c formed in the upper end flange 5a and the lower end flange 5b of the coupling metal 5, and further, the slack interposed between the upper end flange 5a and the intermediate flange 5b. It is also inserted into the wedge hole 8b of the prevention plate 7 and fixed at three locations , and the slack prevention plate 7 is provided with a gap 9 in the vertical direction between the upper end flange 5a and the intermediate flange 5b of the connection fitting 5. there therefore never wedge 6 would easily escape by shock or vibration.

  According to the present invention, members such as a vertical ground material and a horizontal ground material can be reliably connected to each other so as not to be detached.

An example of a pallet is shown, (a) is a perspective view thereof, and (b) is an exploded perspective view showing a connecting portion between a building material and a horizontal material. The connection part of a building material and a horizontal material is shown, (a) is a longitudinal cross-sectional view, (b) is a II line cross-sectional view in (a). (a) is a perspective view showing an example of a pallet, (b) and (c) show a connecting portion between a conventional building material and a horizontal material, (b) is an exploded perspective view, and (c) is a longitudinal sectional view. It is.
