Description

[Detailed description of the invention] (Field of industrial application) This invention is a method for converting wooden square timbers into angle timbers, which is convenient for construction and does not require connecting members such as bolts, which is used in the manufacturing industry of construction materials. Regarding connection fittings.

(Prior art) The present inventor first developed a wood square iron connection fitting (Jikkosho
52-20414) was devised and commercialized.

This wood square iron connection fitting B is shown in Figures 5 and 6.
As shown in the figure, the lower connecting surface 7 of the U-shaped metal flat plate is bent at right angles to the surfaces of the arms 9 and 10 that make up the U shape so that it can hold the square piece of wood 8.
It has a structure in which the head of 10 is bent so as to be hooked on one side of square iron 11.

In its use, the square timber 8 is supported on the lower connecting surface 7 of the flat plate, and the bent portions formed at the heads of both arms 9 and 10 are locked to the square iron 11. 8 to the square iron 11.

Further, when manufacturing this connecting fitting, as shown in FIG. 6, the same shape is cut out from a metal plate 12 of a fixed size and mass-produced.

(Problem to be solved by the invention) However, both arms 9 and 10 of the conventional wood square iron connecting fitting B described above are
Since it has a configuration in which the left and right sides are parallel and stand up at right angles from both ends, when this connecting fitting B is unfolded as shown in FIG.
Since the 0' part forms a parallel gate shape, when the connecting fitting B' is mass-produced and die-cut from a large metal plate 12, a large amount of unnecessary part 13 comes out, resulting in a die-cut product. However, it was extremely uneconomical and had the problem that the product could not be provided at a low price.

The present invention was made to solve the above-mentioned problems, and is formed into an inverted gate shape by a flat hexagonal abutting support piece and a pair of locking pieces extending from this support piece. The purpose is to provide economical fittings for connecting wooden square timbers to angle timbers, which enables mass production without waste.

(Means for Solving the Problems) The means of the present invention for achieving the above-mentioned object is as follows: An abutment support piece whose planar shape is a flat hexagon in the middle part, and from both inner oblique edges of the abutment support piece. It consists of a pair of locking pieces that extend symmetrically and have both edges parallel to each other in the length direction, and the pair of locking pieces have both inner oblique edges facing the abutting support piece. It consists of a connecting fitting for connecting wooden square timbers to angle timbers, which are bent at right angles as folds to form an inverted gate shape.

(Function) With the above-described configuration, the fitting for connecting a wooden square to an angle according to the present invention exhibits the following functions.

When making and using this connection fitting,
First, a connecting fitting in an expanded state consisting of a flat hexagonal abutting support piece and locking pieces extending symmetrically from both inner oblique edges of the flattened metal plate was continuously die-cut from a large metal plate, and then pressed. Using a machine or the like, both inner oblique edges of the locking piece are bent at right angles as creases to form a reverse gate-shaped connection fitting.

When using this connection fitting, for example, first fold the tip end of the locking piece into an inverted U shape so that it can be latched onto the angle piece, and then apply the abutting support piece to the square piece. This abutting support piece and a pair of corresponding locking pieces support the square piece of wood, and the folded portion of the locking piece is hooked onto the angle piece, and the square piece of wood is suspended from the angle piece using the connecting fitting. It is something.

In addition, when punching a large metal plate as described above, the abutting support piece and the locking piece are
Since the inner edge of the cut edge and the outer edge of the uncut edge of the metal plate are made to have the same shape, the die cutting process can be performed continuously without creating unnecessary parts that are wasted during cutting. It can be done.

(Example) Next, an example of a fitting for connecting a wooden square piece to an angle piece according to the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a wooden square timber, which is made of a long square timber and constitutes the ceiling material, etc.

Reference numeral A denotes a metal connection fitting, which is composed of an abutting support piece 2 at the intermediate portion and a pair of locking pieces 4 and 5.

The reference numeral A indicates the connection fitting after completion of the product, and the reference numeral A' indicates the connection fitting in the expanded state after punching.

The contact support piece 2 is formed to have a flat hexagonal planar shape, and has parallel edges A and B having mutually corresponding lengths in the longitudinal direction in the planar state. At both ends of the parallel edges A and B, there are outer oblique edges D and D' and locking pieces 4 and 5 to be described later.
is extended, and the inner beveled edges C and C' formed by bending form a receiving surface for supporting the wooden square timber 1.

3 is an angle material for suspending the wooden corner material 1;
A long metal piece having an L-shaped cross section is used, and a wooden square piece 1 is suspended in a direction perpendicular to the longitudinal direction of the piece.

The pair of locking pieces 4 and 5 are connected to the abutting support piece 2.
Extending symmetrically from both inner beveled edges C and C', respectively,
Both edges E, H and E', H' are formed parallel to each other in the length direction, and both inner oblique edges C, C' are bent at right angles to the abutting support piece 2 as creases. A connecting fitting A formed in an inverted gate shape is obtained.

6 is the abutting support piece 2 and the pair of locking pieces 4;
5. Use a metal plate cut to the specified size to obtain the connecting fitting A' before bending, which consists of
The connecting fittings A' are continuously obtained from this metal plate using a punching machine (not shown), and when punching out the large metal plate 6 described above, the abutting support piece 2 and the engagement As shown in FIG.
and the outer end of the uncut edge d of the metal plate 6 are aligned so that they have the same shape, so that the cutting process can be performed continuously without creating unnecessary parts.

As mentioned above, when forming the connecting fitting A according to this embodiment and attaching the wooden square timber 1 to the angle timber 3,
Connection fittings obtained by cutting into specified shapes before bending
A' is hung in a press and bent at right angles using the roots of the locking pieces 4 and 5, that is, the inner oblique edges C and C' as creases, to form an inverted gate-shaped connecting fitting A.

Then, the contact support piece 3 of the formed connection fitting A is applied to the lower surface of the wooden square timber 1, and further, the wooden square timber 1 is
While applying the locking pieces 4 and 5 of the connecting fitting A to the angle piece 3, bend the locking pieces 4 and 5 of the connecting fitting A into a U-shape, hang this bent piece on the angle piece 3, and attach the wooden square piece 1 to the angle piece 3 using the connecting fitting A. It is something to be installed.

(Effects of the invention) The connecting fitting for connecting a wooden square to an angle according to the present invention, which is constructed as described above, has a structure in which the abutting support piece that supports the wooden square has a flat hexagonal shape, and Since the locking piece is also configured to extend from the inner oblique edge of the hexagonal shape of the corresponding contact support piece, when continuously cutting out a large metal plate, efficient cutting with less wasted parts is possible. Since it can be carried out, it is excellent in mass production and can be produced and provided at low cost, which has a special effect.
