DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for connecting two metal plates of a predetermined size in a plane direction.

[0002]

2. Description of the Related Art For example, when a metal partition plate is provided inside an assembled house such as a storeroom, the metal plate is usually formed in a fixed size. Must connect the metal plates in the plane direction. In this case, conventionally, the ends of the metal plates to be connected are superimposed and directly fixed by screws, welding, or the like, or the ends of the two metal plates are butted together, and both sides of the butted portion are connected to a square cylinder for connection. , And the overlapping portion is fixed by screws, welding, or the like.

[0003]

However, screwing and welding are troublesome, and when a sheet metal contractor works, the connecting square tube must be specially treated and connected from both sides of the metal plate. When a metal tube is used, when a metal plate is large, a single person cannot do it, so a plurality of workers are required.

It is an object of the present invention to provide a metal plate connecting structure which can solve the above problems and can be connected simply and surely without using screws or welding and can reduce the cost. Make it an issue.

[0005]

In order to solve the above-mentioned problems, a connecting structure of metal plates according to the present invention is formed by connecting two metal plates in the direction of the surface thereof and bending each of them into a U-shape. A pair of metal plate-shaped connecting members are opposed to each other, and the ends of both side pieces of each connecting member are overlapped and bent inward to form a connecting tubular body,
It is characterized in that the ends of the metal plates to be connected are connected by folding between the bent pieces superposed on the bending sides on both sides of the cylindrical body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of a partition plate for partitioning the interior of a storeroom or the like. The partition plate is formed by three metal plates 2, 3 and 3 between a rectangular frame 1 formed by sheet metal working. 4 are arranged, and the metal plates 2, 3, and 4 are connected via a tubular body 5 formed by sheet metal processing.

As shown in FIG. 2, the frame member constituting the frame 1 is composed of two divided frame members 1a and 1b, and one of the divided frame members 1a is formed by bending into a substantially "" shape. The other frame member 1b is bent in a U-shape. The metal plates 2, 3, and 4, together with the other divided frame member 1b, are pressed into the open portions of one divided frame member 1a.

As shown in FIG. 3, the tubular body 5 is constructed by assembling two connecting members 5a and 5b. One connecting member 5a is formed by bending a metal plate (iron plate or the like) into a U-shape, and forming bent pieces 7 at the ends of both side pieces 6 into a concave shape so as to open outward. The other connecting member 5b is formed by bending a metal plate (iron plate or the like) into a U-shape, and also bending the ends of both side pieces 8 inwardly into a U-shape to form a bent piece 9. The two connecting members 5a, 5b face each other, and each connecting member 5a, 5b
The end connecting pieces 7 and 9 of both side pieces 6 and 8 are overlapped with each other to form an integral connecting tubular body 5.

The connection-side ends of the metal plates 2 and 3 to be connected are folded back in a U-shape to form folded portions 10 and 11.

The folded portions 10 and 11 at the connection side ends of the two metal plates 2 and 3 are folded between two bent pieces 7 and 9 that are overlapped on the connection side of the tubular body 5 respectively. The two metal plates 2 and 3 are connected via a tubular body 5. The connection of the metal plates 3 and 4 is the same.

In connecting the metal plates 2 and 3 via the tubular body 5, first, the connecting side ends of the metal plates 2 and 3 to be connected are folded back in a U-shape. Is formed. Then, as shown in FIG. 3, the folded portions 10 and 11 of the metal plates 2 and 3 to be connected are superimposed on the outside of the bent piece 7 of one connecting member 5a. Thereby, the groove 12 is formed inside the two bent portions. Next, the bent piece 9 of the other connecting member 5b may be inserted from one end of the groove 12 and beaten. Thereby, the connection structure shown in FIG. 2 is obtained.

As described above, the two metal plates 2 and 3 are connected via the connecting tubular body 5.
Is formed by overlapping the bent pieces 7 and 9 of the pair of metal plates 2 and 3 and bending them inward, and thus can be manufactured by a sheet metal trader. The same applies to the operation of folding the ends of the metal plates 2 and 3 to be connected between the bent pieces 7 and 9. Some assembled houses such as metal storage and garages are manufactured by sheet metal contractors.If it is necessary to connect metal plates, such as when creating a partition plate inside, procure a square tube for connection separately Since the connection can be easily and reliably performed by one person by sheet metal working without connecting with screws or welding, the manufacturing cost can be reduced.

Claims (1)

(57) [Claims] In a connection structure in which two metal plates are connected in the plane direction, a pair of metal plate connection members bent in a U-shape are opposed to each other, and both ends of each of the connection members are opposed to each other. To form a connecting tubular body by folding them on each other and inwardly connecting the ends of the metal plates to be connected between the folded pieces overlapped on the bending sides on both sides of the tubular body.
