Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a plate body used for a plate structure constructed by combining plate bodies such as containers, cabinets, and racks.
In addition, the present invention relates to a joint structure of plate bodies in which adjacent plate bodies having separate structures are connected to each other at a substantially right angle.

[Prior Art] Conventional connection structures of this type of plate body include a dovetail groove connection as shown in FIG. 7 and an interlocking connection as shown in FIG.

[Problems to be solved by the device]

In the former of the above-mentioned conventional techniques, the dovetail groove a and the protrusion b to be fitted into the dovetail groove must be provided in the entire length of the joint portion, and the forming process is troublesome, and both plate bodies are involved. However, there was a problem that it tended to shift in the direction of the dovetail groove.

Also, in the latter case, the processing and assembly of the joints of both plates are simple, but the joints of both plates must be joined with an adhesive or a joining member such as bolts, resulting in joining. There was a problem that it was troublesome.

As shown in Japanese Utility Model Publication No. 50-13906 as another example of the latter interlocking combination of the above-mentioned conventional techniques, a plurality of openings provided at the edge of one plate are There is one in which both plate bodies are joined by inserting and inserting a plurality of projecting portions provided on the plate body. However, in this conventional one, due to the configuration, the edge portions of both plate bodies are In addition, there is a problem that it protrudes from the corner of the assembly, which becomes an obstacle in handling the assembly, and such a configuration can be applied only to a flexible plate body, It could not be used for joining structural plates having a predetermined strength.

The present invention has been conceived in view of the above, and it is possible to combine both adjacent plate members with a simple structure and without using an adhesive or other connecting member, and to provide a rigid plate member. Even so, it is an object of the present invention to provide a plate connecting structure in which the ends of each plate can be connected without protruding from the corners of the assembly.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the plate connecting structure according to the present invention is provided with an uneven portion at each end of adjacent plate members having separate structures, and the end parts of both plate members are interdigitated with each other. In a plate connecting structure in which the plate members are fitted into each other and are connected at a substantially right angle, in a direction along the side faces of the convex portions of both plate members, on the end faces of the concave portions of both plate members that abut each other and the side faces of the convex portions. In addition, at least, there is provided a step portion that engages in the pulling direction of each interlocking portion.

[Action]

The end portions of both plate bodies are joined together in an interlocking manner by fitting the uneven portions together. Then, at this coupling portion, the stepped portions provided on the end surface of the concave portion and the side surface of the convex portion that are in contact with each other are locked in the pulling direction of the interlocking coupling.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

In the figure, reference numerals 1 and 2 denote plate bodies that are joined to each other at substantially right angles, for example, a bottom plate and a side plate, each of which is formed into a hollow plate shape by blow molding using a thermoplastic such as polyethylene or polypropylene. There is. A concave portion 3 and convex portions 4, 4 are provided at the side end portion of the bottom plate 1, and a convex portion 5 that fits into the concave portion 3 of the bottom plate 1 is provided at the side end portion of the side plate 2.
And the recesses 6,6 that fit into the protrusions 4,4 of the bottom plate 1,
Both plates 1 and 2 are fitted with the above-mentioned fitting parts so that the bottom plate 1
The side end surface of the side plate 2 is placed and abutted on the upper end portion of the above so as to be assembled into a combined shape.

A protrusion 7 is provided on the end surface of the recess 3 of the bottom plate 1, and a groove 8 with which the protrusion 7 is engaged is provided on the side surface of the protrusion 5 of the side plate 2 that fits into the recess 3 of the bottom plate 1. There is. Also, the convex portion of the bottom plate 1
Protrusions 9 and 9 are provided on the side surfaces of 4, 4 and the concave portion 5 of the side plate 2,
Grooves 10, 10 with which the protrusions 9, 9 of the bottom plate 1 are engaged are provided on the end surface of the groove 5. The projections 9, 9 on the bottom plate 1 side have an arcuate outer portion of the coupling structure.

In the above structure, the bottom plate 1 and the side plate 2 are coupled to each other by the bottom plate 1
The side plate 2 is formed into a substantially right angle with respect to the end of the plate, and the end of the side plate 2 is moved in the plane direction of the bottom plate 1 to fit the concavo-convex parts at both ends to assemble. As a result, the protrusion 7 provided in the recess 3 of the bottom plate 1 engages with the groove 8 provided in the protrusion 5 of the side plate 2 (second
Also, the projections 9 and 9 provided on the convex portions 4 and 4 of the bottom plate 1 engage with the grooves 10 and 10 provided on the end faces of the concave portions 6 and 6 of the side plate 2 while elastically deforming (Fig. 3). ), The side plate 2 is locked to the bottom plate 1 in the lateral direction of the bottom plate 1 by the step portions 13, 13 formed by the engagement of the protrusion 7 and the groove 8, and the projections 9, 9 and the groove 10, The side plate 2 is locked in the plane direction of the bottom plate 1 at the step portion 14 formed by the engagement of 10. In this way, both plates are
It is engaged in the direction along the side surfaces of 4,5.

Although the side plate 2 is engaged with one side of the bottom plate 1 in the above embodiment, in the case of forming the box body 11 as shown in FIG. The side plate 2 is connected to. Adjacent ones of the side plates 2 are fixed by bolts 12.

Further, the cross-sectional shape of the portion along the line AA in FIG. 1 may be made into a "key" shape as shown in FIG. 5, and the cross-sectional shape of the portion along the line BB as shown in FIG.

In the embodiment shown in FIGS. 4 and 5, both plate members are formed in a direction along the side surfaces of the respective convex portions by the step portions 13 ', 14' constituted by the hook-shaped portions and in the interlocking portion. It is locked in the pulling direction.

[Effect of device]

According to the present invention, the two adjacent plate bodies assembled in a substantially right-angled shape can be combined with each other with a simple structure and without using an adhesive or other connecting member, and the plate body of a rigid body can be connected. Also, the ends of the plate members can be joined together without protruding from the corners of the assembly.
