Abstract

(57) [Summary] [Purpose] To connect gratings easily and reliably. [Structure] Since elastic clamping pieces 7 having elastic contact ridges 8 are provided at appropriate positions on the end bar 4 of the grating 1 at intervals corresponding to the wall thickness of the end bar 4, the adjacent grating 1 is attached to the end bar 4 as described above. The end bar 4 is sandwiched by the end bar 4 of the grating 1 already laid and the elastic contact ridges 8 of the elastic sandwiching piece 7 just by locating it inside the elastic sandwiching piece 7 and dropping it from above. It is possible to connect the grating 1 without loosening only by laying operation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting device for connecting adjacent gratings of gratings used for various applications such as being attached to a side groove.

[0002]

[Prior Art]

 It is necessary to fix adjacent gratings in order to connect adjacent gratings to each other so as to keep them loose or prevent theft of the gratings. In some cases, the fixing may not be able to fix the grating to the loading shelf at the end when fixing the roller. As another fixing means in this case, there is a method of connecting adjacent gratings. As shown in FIG. 4, a conventional connecting fitting x used in such a method has a substantially rectangular cross section in which an elastic mouth portion y formed by a pair of curved pieces that expands outward is formed in the lower portion. The outermost two end bars 4 and 4 of the adjacent gratings 1 and 1 are externally fitted by straddling from above from the upper side by the expansion operation of the elastic mouth portion y to surround the end bars 4 and 4 and the side plate portions z and 4 thereof. The pair of end bars 4 and 4 are sandwiched by z.

[0003]

[Problems to be solved by the device]

 By the way, with such a configuration, the end bars 4 and 4 can be moved in the direction of the arrow in the connecting fitting x, and the side plates z and z thereof are not elastically acted, so that the holding thereof is insufficient. In addition, it was troublesome that each connecting metal fitting x had to be mounted. It is an object of the present invention to provide a grating connecting device that can hold gratings without loosening and that can be easily connected by laying gratings on site.

[0004]

[Means for Solving the Problems]

 The present invention is directed to a lower edge of an end bar located on the outermost side of a grating that is laid next to each other on the left and right, and between a bar support portion that horizontally projects outward and an outer surface of the end bar. It is characterized in that a connecting metal fitting is fixedly provided, which is formed to have an interval approximately equal to the wall thickness and is connected upward from the bar supporting portion and which is provided with an elastic clamping piece formed with an elastic contact ridge that bulges inward. It is a thing.

[0005]

[Action]

 When laying gratings, first lay the gratings with the elastic pinching pieces on the outside, and then lay the adjacent gratings densely. Inserted between the pieces, the elastic ridges make elastic contact with the inner surface of the end bar, so that the gratings are connected to each other.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a grating, in which bearing bars 2 are arranged in parallel at regular intervals, and each has a rectangular plate shape connected by a twist bar 3 orthogonal to the above. Then, the end bars 4 and 4 are arranged on the outermost side thereof. When the grating 1 is attached to, for example, a side groove, the grating 1 is supported by a receiving frame 20 and arranged in large numbers along the groove path 21 (see FIG. 3).

Reference numeral 10 denotes a connecting fitting according to the present invention, which has a U-shaped cross section as shown in FIG. 2 and has an inner width corresponding to approximately twice that of the end bar 4. Further, as will be described later, the side portion projecting upward from one end of the bottom piece constituting the bar support portion 6 is used as the fixing piece 5, and the side portion projecting upward from one end of the bottom piece is used as the elastic clamping piece 7, and the elastic clamping An elastic contact ridge portion 8 that bulges inward is formed on the piece 7.

The connecting fitting 10 is externally fitted to the lower edge of one end bar 4 of the grating 1, and the fixing piece 5 is welded and fixed to the inner surface side of the end bar 4. In this joined state, a space corresponding to the thickness of the end bar 4 is formed between the elastic holding piece 7 and the outer surface of the end bar 4, and the bottom piece corresponding to this space is used as the bar support portion 6. The connecting fittings 10 are fixed to the end bar 4 at two positions in the length direction.

A procedure for attaching the grating 1 will be described. First, the grating 1 is supported by the receiving frame 20 (see FIG. 3) with the connecting metal fitting 10 positioned outside and is attached to the groove 21. Then, the grating 1 to be next adjoined is dropped from above so as to come into close contact with the end bar 4 of the grating 1 to which the end bar 4 without the connecting fitting 10 has already been attached. By this dropping operation, as shown in FIG. 2, the end bar 4 is internally fitted from above between the end bar 4 of the grating 1 and the elastic holding piece 7, and the lower end thereof is supported by the bar supporting portion 6. Then, in this internal fitting state, the elastic contact ridge 8 of the elastic holding piece 7 elastically contacts the inner surface of the end bar 4, and a holding force is applied. Thus, by simply laying the gratings 1, the gratings 1 can be sequentially connected as shown in FIG.

[0010]

[Effect of the device]

 According to the present invention, as described above, since the elastic clamping pieces 7 having the elastic contact ridges 8 are provided at appropriate positions on the end bars 4 of the grating 1 at intervals corresponding to the wall thickness of the end bars 4, the adjacent grating 1 The end bar 4 is held between the end bar 4 of the grating 1 and the elastic contact ridge 8 of the elastic holding piece 7 which have already been laid by simply locating the end bar 4 inside the elastic holding piece 7 and dropping it from above. It is possible to connect the gratings 1 without loosening due to the pressure contact elastic force of the elastic contact ridges 8 simply by laying down each grating 1, and it is possible to perform the connecting operation easily and reliably. It has the effect.
