Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed metal article for fixing wood such as a hanging tree receiving material to a supporting member such as shaped steel.

[0002]

2. Description of the Related Art As a conventional example of the above fixed hardware, there is one shown in FIG. In the figure, reference numeral 26 designates an H-shaped steel, which is arranged laterally in the attic of a residential building, and a wooden hanging tree support member 27 is orthogonal to the H-shaped steel 26 on the H-shaped steel 26. Has been erected. 28 is a hanging tree, the upper end of which is fixed to the side surface of the hanging tree receiving material 27, and the lower end of which is fixed to the side surface of the field edge 30 framed on the upper surface of the ceiling plate 29.

Reference numeral 31 denotes a fixed metal member for fixing the hanging tree support member 27 to the H-shaped steel 26, which is a strip-shaped steel plate body,
On one side in the longitudinal direction, a fitting recess 33 into which the flange portion 32 of the H-shaped steel 26 is inserted is formed from one end edge in the width direction toward the center side in the width direction. The fixed hardware 31 is nailed to the side surface of the hanging tree receiving member 27 in a state where the flange portion 32 of the H-shaped steel 26 is inserted into the fitting recess 33, whereby the hanging tree receiving member 27
Was fixed to the H-section steel 26 side.

[0004]

However, in the conventional fixed metal fitting 31, since the fitting recess 33 is simply formed as a rectangular notch from one edge in the plate width direction, various flange portions 32 having different thicknesses can be formed. In order to deal with this, it is necessary to prepare the fixed metal fittings 31 of various shapes, which complicates the construction site, increases the material cost, and complicates inventory management.

In view of such circumstances, it is an object of the present invention to provide a fixed hardware which can reduce material cost and construction cost and simplify inventory control.

[0006]

[Means for Solving the Problems] In order to achieve the above object,

Embodiments of the present invention will be described in detail below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a fixed metal piece according to the present embodiment, which is composed of a vertically elongated strip-shaped metal plate body 2 made of steel. This fixed hardware 1 is provided with a fitting concave portion 5 into which a flange portion 4 of an H-shaped steel (shaped steel) 3 is inserted, on one side in the longitudinal direction of a metal plate body 2. It is formed by notching a laterally long rectangular shape from one edge in the width direction toward the center side in the same direction.

An insertion guide portion 6 for facilitating the insertion of the flange portion 4 is formed on the inlet side (left side in FIG. 1) of the fitting concave portion 5. This insertion guide portion 6 is formed by notching the metal plate body 2 at the upper part of the fitting recess 5 on the inlet side in a tapered shape so that the entrance side of the fitting recess 5 is located at one end side in the width direction of the metal plate body 2. It is designed to gradually widen as it goes.

Reference numeral 7 denotes a metal plate body from the deepest part of the fitting recess 5.
2 is a notch extending straight toward the center side in the longitudinal direction, and a downward holding piece 8 is formed above the fitting recess 5 via this notch 7. Therefore, FIG.
As shown in FIG. 2, when the tip of the flange 4 is brought into contact with the insertion guide 6 and the fixed metal piece 1 is forcibly inserted in the direction of the arrow in the figure by hitting the fixed metal piece 1 from behind with the hammer, as shown in FIG. Bends or curves to one side in the plate surface out-of-plane direction, so that the fixed metal fitting 1 can be engaged with the flange portion 4 having a thickness T larger than the width W of the fitting recess 5.

As shown in FIG. 3, a chamfer 9 may be provided at the lower end edge of the sandwiching piece 8 so that the sandwiching piece 8 is easily bent during the forced insertion. Reference numeral 10 is a hooking recess for engaging the fixed metal piece 1 with the lip portion 12 of the channel material 11. The locking recess 10 is formed by cutting out one side of the metal plate body 2 on the other side in the longitudinal direction.
A lateral recess 13 for accommodating the lip portion 12 of the channel material 11,
The side plate portion 14 of the channel material 11 and the vertical recess 15 are formed into an approximately L shape.

On the inlet side of the vertical recess 15, a first taper side 16 inclined in the opposite direction to the horizontal recess 13 and a second taper side 17 inclined in the same direction as the horizontal recess 13 are cut out. Moreover, the third tapered side 18 is formed by obliquely notching the inside of the corner portion of the horizontal concave portion 13 and the vertical concave portion 15. In order to attach the fixed hardware 1 to the channel material 11 via the retaining recess 10, first, as shown in FIG. Insert it into the retaining recess 10. After that, as shown in FIG. 5, when the inside of the side plate portion 14 contacts the second tapered side 17, the fixed hardware
When 1 is rotated toward the outer surface of the channel material 11,
As shown in FIG. 6, a state in which the lip portion 12 is housed in the lateral recess 13 and the side plate portion 14 is housed in the vertical recess 15 is obtained,
As a result, the fixed hardware 1 can be attached extremely easily and firmly.

Numerals 19 are through holes for nails or setscrews, and in this embodiment, they are provided at three positions in the longitudinal direction of the metal plate body 2 and in the center. 7 and 8 show an example of construction of an attic using the fixed hardware 1. In the figure, reference numeral 20 denotes a building pillar, on the upper end of which H-section steel 3 is horizontally arranged. On the upper surface of the H-shaped steel 3, a wooden hanging tree support member 21 is erected orthogonally to the H-shaped steel 3, and on the side surface of the hanging tree support member 21, a plurality of hanging trees are arranged at predetermined intervals in the longitudinal direction. 22 is fixed in a hanging shape. The hanging tree 22 supports the ceiling board 23 from above by fixing its lower end to a field edge 24 framed on the upper surface of the ceiling board 23.

In this case, the fixed hardware 1 has a fitting recess 5
It is attached to the H-shaped steel 3 so that it can be inserted into the upper flange 4 of the H-shaped steel 3, and then fixed to the side surface of the hanging tree receiving member 21 by nailing or the like. Fix it. At this time, according to the fixed hardware according to the present embodiment, even if the thickness of the flange portion 4 changes, the fixed hardware can be processed in the same manner as described above.
Since 1 can be forcibly inserted, the hanging tree support member 21 can be attached to various H-shaped steels 3 arranged at the back of the hut with one fixed metal fitting 1, and thus the construction cost and material cost can be reduced.

On the other hand, in FIGS. 9 and 10, the channel material 11 is used as a support member for the hanging tree receiving material 21 with its cross section facing upward. In this case, the fixed hardware 1 is used upside down and attached to the channel member 11 so that the lip 12 is housed in the hooking recess 10, and then the fixed hardware 1 is attached to the side surface of the hanging tree receiving member 21. It can be fixed by nailing or the like.

The present invention is not limited to the H-section steel 3, but can be applied to all other section steels having the flange portion 4, such as I-section steel and T-section steel. Further, the hooking recess 10 can be engaged not only with the channel member 11 but also with a supporting member having an L-shaped cross-section end portion of the same kind.

[0019]

As described above, according to the present invention,
Even if the thickness T of the flange 4 is larger than the width W of the fitting recess 5, the fixed metal fitting 1 can be engaged with the shape steel 3, so that even if the type of the shape steel 3 is changed, only one fixed metal fitting 1 can be used. Therefore, it is possible to reduce the material cost and the construction cost and simplify the inventory management.

According to the second aspect of the invention, since the fixed metal piece 1 can be engaged with the channel material 11 and the like, the material cost can be further reduced.
