Description

[Detailed description of the invention] The present invention relates to a joining fitting used when joining C-shaped or I-shaped materials made of metal or synthetic resin used for architecture and construction. , A joining fitting that can firmly join C-shaped or I-shaped shaped materials in an orthogonal or parallel state using a single joining fitting without twisting, twisting, falling down, etc. of the joining fitting or the forming materials. is intended to provide.

Conventionally, a joining fitting A shown in Fig. 6 has been used as a fitting for joining C-shaped or I-shaped materials in an orthogonal or parallel state. Since the hanging piece C only extends from one side edge, when the bolt D is tightened, the hanging piece C tends to twist in the direction shown by the arrow X and come off from the flange F of the profile E. E also had drawbacks such as falling in the direction indicated by the double arrow Y and being easily uncoupled.

The present invention provides a joining fitting free of the above-mentioned drawbacks by having the configuration described in the claims of the utility model registration.

The configuration of the illustrated example will be explained below.

1, 2, and 3 show an example of the implementation of the present invention, in which a substrate section 1 made of metal such as a steel plate is made of metal such as a base plate 1 from which two parallel edges 2 and 3 are connected to each other in the same direction. The hooking pieces 6,
7 has been extended.

The hanging piece 6 extending from the side edge 2 is short.
The hanging piece 7 extending from the other side edge 3 is long, and a gap l corresponding to the length L of the web 8 of the profile 4 is formed between the lower ends of the hanging pieces 6 and 7.

Furthermore, the flange 1 of another profile 19 to be joined is attached to both the hook pieces 6 and 7 from the lower end toward the base plate.
Notches 9 and 10 having a width V corresponding to the width W' of 9' are formed. The length H of the notch 9 of the hanging piece 6, which is a common part of the notches 9 and 10, is longer than the length of the web of the shape material 19 to be joined, which is the shape material 19 in the illustrated example.

At the lower end of the short hanging piece 6 mentioned above, a hanging claw 11 is formed which faces diagonally upward inward, and at the lower end of the long hanging piece 7, a hook 11 is formed which faces inward at right angles and corresponds to the width W of the flange 5 of the profile 4. A bent piece 12 having a corresponding length h is formed, and a hook 13 facing inward and diagonally upward is formed at the tip of the bent piece 12.

In addition, a female threaded portion 14 is provided at the center of the substrate portion 1 described above.
is formed, and a fastening bolt 15 is screwed into this. Of course, the female threaded portion 14 may be formed by welding a nut.

The joining fitting having the above-described structure is used as shown in FIG. 4 or 5, for example.

That is, in FIG. 4, the shape material 4 is inserted using the spacing l between the lower ends of the hanging pieces 6 and 7, and the end edge 16 of the flange 5 is hung on the hanging claw 11 of the short hanging piece 6. At the same time, place the flange 17 of the profile 4 on the bent piece 12 of the long hanging piece 7, and
8 on the hook 13.

A section 19 perpendicular to the other section 4 is inserted onto the flange 5 of the section 4 using the notches 9 and 10 and placed on the flange 5, and then the bolt 15 is screwed in to place the section 19 on the section 4. 19 is fixed.

In the above-mentioned joining structure, the molded material 4 is supported from both sides by the inner surface of the hanging piece 7 and the hanging claws 11 and 13, and the molded material 4 also rests on the upper surface of the bent piece 12. The joining fittings and the mold material 4 maintain a stable engagement state without inclining, twisting, or inclining, and similarly, the mold material 19 is also engaged from both sides by the notches 9 and 10, and the mold material 4 Since it rests on the flange 5 of the flange 5, a stable state of engagement can be maintained. The shape material 19 does not need to have the same dimensions as the shape material 4, and the width W' of the flange 19' matches the width V of the notches 9 and 10, and the width W' of the flange 19' matches the width V of the notches 9 and
The web may have any size as long as it can be inserted into the length H of the web.

FIG. 5 shows a state in which the mold members 20 and 21 are stacked vertically in parallel and joined together, and the mold material 20 is attached to the fourth
Similar to what is shown in the figure, the shape member 21, which is anchored to the joining fittings, is inserted into the space w between the hooking pieces 6 and 7, and bolts 22 are tightened.

As is clear from the above description, special joining fittings according to the present invention are used depending on the type of mold material.

The joining fitting of the present invention has the structure and function explained above, and a single joining fitting can connect a C-shaped or I-shaped material from both sides of the forming material in an orthogonal state or a parallel state. Since it can be supported and fastened with bolts, there is no twisting, twisting, collapse, inclination, etc. of the joining fittings or shapes, and it is possible to easily realize a strong joint.
