Description

  The present invention relates to a corner fixing bracket made of wood for fixing a connecting portion such as a beam and a beam, or a beam and a beam girder.

  Conventionally, connecting portions such as beams and beams of a wooden house and beams and beam girders are fixed by using a nail or a battledore bolt.

The fixing of the connecting portion using the conventional nail has a drawback that it cannot be fixed with sufficient strength.
In addition, the method using battledore bolts has only a function of pulling beams and beam girders and must form bolt insertion holes, and the work is difficult, and the strength of beams and beam girders is reduced by the bolt insertion holes. There was a drawback of lowering.
JP 2000-257170 A

  In view of the conventional drawbacks as described above, the present invention prevents misalignment between a beam and a beam girder, is easy to mount, and can fix a connection portion with sufficient strength, and a bolt is inserted into the connection portion. An object of the present invention is to provide a wood corner fixing bracket that can be attached without forming a hole.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

  In order to achieve the above object, the present invention provides an L-shaped fixing bracket body, a plurality of pin-shaped nails punched and formed on the long side plate of the one fixing bracket body, Crank-like shape formed through one fixing bracket consisting of a plurality of pin-shaped nail insertion holes formed in the short side plate of the fixing bracket body, and a bent portion overlapping the short side plate of this one fixing bracket The other fixing bracket body, a plurality of pin-shaped nails punched and formed on the base portion of the other fixing bracket body, and the pin of the short side plate of the one fixing bracket on the overlapping portion of the other fixing bracket body A corner fixing bracket made of wood is constituted by the other fixing bracket composed of an insertion hole of a nail or the like formed in a corresponding portion with a shaped nail insertion hole.

  As is clear from the above description, the present invention has the following effects.

(1) One fixing bracket body formed in an L shape, a plurality of pin-shaped nails formed by punching on the long side plate of the one fixing bracket body, and the short side plate of the one fixing bracket body One fixing bracket comprising a plurality of pin-shaped nail insertion holes formed, and the other crank-shaped fixing bracket main body formed through a bent portion overlapping with the short side plate of the one fixing bracket, A plurality of pin-like nails punched and formed in the base part of the other fixing metal body, and the overlapping part of the other fixing metal body corresponds to the pin-like nail insertion hole of the short side plate of the one fixing metal body. Because it is composed of the other fixing bracket made of an insertion hole such as a nail formed in the part, one fixing bracket is positioned at the corner of a beam or beam girder, and a plurality of pin-shaped nails are After fixing the beam or beam girder with a hammer, the other fixing metal A plurality of overlapping pin-like nails and a plurality of pins of the base plate are inserted into the plurality of pin-like nail insertion holes of the short side plate of one fixing bracket. By fixing the shaped nail into the beam girder and the beam with a hammer, one fixing bracket and the other fixing bracket are integrated with each other, and the connecting portion such as the beam and beam girder can be securely fixed.
Therefore, even if an earthquake, a contraction of wood, or the like occurs, the connection portion such as the beam and the beam girder can be firmly fixed without moving.

(2) According to the above (1), since only the operation of driving and fixing with a hammer is required, anyone can easily perform it easily.

(3) According to the above (1), it is not necessary to form the bolt insertion hole in the beam or beam beam as in the conventional case, so that it can be used without reducing the strength of the beam or beam beam.

(4) According to the above (1), since one fixing bracket and the other fixing bracket can be formed by punching, processing is easy and can be manufactured at low cost.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the best mode for carrying out the present invention shown in FIGS. 1 to 14, reference numeral 1 denotes a wood corner fixing bracket according to the present invention for fixing a connecting portion 4 between a beam 2 and a beam girder 3 of a wooden house. The wood corner fixing bracket 1 is composed of one fixing bracket 5 formed in an L shape and the other fixing bracket 6 overlapping the short side plate 5 a of the one fixing bracket 5.

  As shown in FIGS. 3 to 7, the one fixing bracket 5 is formed by punching one fixing bracket body 7 formed in an L shape and a long side plate 5 b of the one fixing bracket body 7. A plurality of pin-shaped nails 8 projecting in a substantially right angle direction, a plurality of pin-shaped nail insertion holes 9 formed in the short side plate 5a of the one fixing metal body 7, and formed as necessary. And a bolt insertion hole 19 for a wing plate bolt.

  As shown in FIGS. 8 to 12, the other fixing bracket 6 is a crank-shaped other fixing bracket body 11 formed through a bent portion 10 so as to overlap the short side plate 5 a of the one fixing bracket 5. A plurality of pin-like nails 12 that are punched and formed in the base plate 6a of the other fixing metal body 11 and project in a substantially right angle direction, and the overlapping portion 6b of the other fixing metal body 11 A plurality of tips whose tip ends are located at substantially the same position as the tip of the pin-shaped nail 12 that is punched and formed so as to be inserted into the pin-shaped nail insertion hole 9 of the fixing metal 5. The pin-shaped nail 13 and a bolt insertion hole 19 for a wing plate bolt formed as necessary are configured.

In the corner fixing bracket 1 made of wood having the above structure, one fixing bracket 5 is positioned at the corner portion of the connecting portion 4 between the beam 2 and the beam girder 3 as shown in FIG. 13, the long side plate 5b is pressed, and the air hammer A plurality of pin-like nails 8 at the part are inserted into the beam girder 3 and fixed with a hammer 14 such as a hammer.
Thereafter, a plurality of overlapping pin-like nails 13 are formed on the short side plate 5a of one fixing bracket 5 fixed to the beam girder 3 as shown in FIG. A plurality of pin-like nails 12 and a plurality of overlapping parts are inserted into the pin-like nail insertion holes 9, and the base plate 6 a and the overlapping portion 6 b of the other fixing metal 6 are struck with a hammer 14. By fixing the pin-shaped nail 13 so that it is not inserted into the beam 2, one fixing bracket 5 and the other fixing bracket 6 overlap each other in an L shape, and the connecting portion 4 of the beam 2 and the beam girder 3 is integrally formed. It is fixed to the corner portion and the connection portion 4 between the beam 2 and the beam girder 3 can be reinforced.
Moreover, a battledore bolt can be attached using the bolt insertion holes 19 for the battledore bolt.
{Different forms for carrying out the invention}

  Next, different modes for carrying out the present invention shown in FIGS. 15 to 31 will be described.
