[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a square bar connecting fitting for assembling square bars such as columns, beams and girders.

[0002]

2. Description of the Related Art In wooden construction, in order to assemble square timbers such as pillars, beams and girders, tenons and grooves are carved at the ends of the timbers to combine the tenons and grooves.
In addition, after the square timbers have been assembled, the combined parts may be reinforced with metal fittings.

[0003]

As described above, in the past, the end of the timber was worked to assemble the timber, but in this case, a long timber is prepared at the sawmill, and the timber is worked. The length of the timber was wasted because it was shortened to an appropriate length, which was not preferable in terms of saving resources. Further, the work of the square wood requires skill and cannot be easily performed. Further, although reinforcing metal fittings were sometimes used, such metal fittings were only for reinforcement and could not be relied on alone.

[0004] Therefore, an object of the present invention is to provide a corner-piece connecting metal fitting, thereby saving resources, and enabling the square-piece to be easily assembled with sufficient strength.

[0005]

In order to solve the above-mentioned problems, in the square metal connection fitting of the present invention, an L-shaped flat plate portion and an L-shaped bent portion extending from each end of the flat plate portion are provided. One of the side plate portion and has an L-shaped connecting frame consisting of, projecting a pair of connecting plate opposite the intersection portion of the L-shaped on said plate, said L-shaped connection frame each side plate portion and said A plurality of holes are formed in each connecting plate to form the L-shaped connection.
The frame is equipped with brace fittings .

[0006]

According to the square timber connecting fitting of the present invention, two square lumbers are held in an L-shaped connecting frame, and another square lumber is sandwiched between a pair of connecting plates so as to project. If, for example, nails are driven into a plurality of holes respectively provided in the side plate portion and each connecting plate, the three square members can be connected in the vertical, horizontal and height directions.

[0007] Also, prepare a plurality of this square bar connection fittings
Then, assemble a rectangular wooden frame using these timber connection fittings , and bridge the braces between the brace attachment fittings of each timber connection fitting on the diagonal line of this wooden frame, the strength of this wooden frame will be remarkably increased. improves. That is, not only can a plurality of timbers be connected, but the strength of a structure called a wooden frame made of these timbers can be significantly improved.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a square bar connecting fitting according to the present invention. In the figure, an L-shaped connection frame 1 has a U-shaped cross section, and an L-shaped flat plate portion 2
And two side plate parts 3 and 4 hanging from each end of the flat plate part 2. A plurality of holes 5 are provided in the side plate portions 3 and 4.

On the flat plate portion 2 of the L-shaped connection frame 1, a pair of column connecting plates 6 and 7 facing each other are projected. A plurality of holes 8 are also provided in these pillar connecting plates 6 and 7.

Further, on the flat plate portion 2 of the L-shaped connection frame 1,
Two brace connecting plates 9 and 10 are provided so as to project along each side of the L-shape. Further, another brace connecting plate 11 is provided at a portion inside the corner of the L-shaped connection frame 1, that is, at a portion where the inner side plate portion 3 is bent. Each of these brace connecting plates 9, 10, 11 is provided with one hole 12 for attaching the brace.

The L-shaped connecting frame may be formed by connecting two linear frames having a U-shaped cross section at a right angle.

FIG. 2 shows an example of a form of use of the above-mentioned square bar connection fitting, and here, the connection fitting is shown from above. In the figure, the L-shaped connection frame 1 is formed on each of the bases 21 and 2.
2 is arranged in an L shape and is held inside. In addition, a pillar 23 is sandwiched between the pair of pillar connecting plates 6 and 7 so as to project. In this state, the side plate portions 3, 4 of the L-shaped connection frame 1
A plurality of holes 5 formed in the column, and column connecting plates 6 and 7
When a plurality of nails are driven through the plurality of holes 8 formed in the base, the bases 21 and 22 and the pillar 23 are arranged in the vertical, horizontal, and height directions, assembled, and fixed.

Since three pieces of timber can be assembled in this way, it is not necessary to prepare a long timber wastefully, and it is not necessary to carve a tenon or a groove at the end of the timber, thus saving resources. Further, since the L-shaped connecting frame 1 has a U-shaped cross-section, this connecting fitting has sufficient strength. Therefore, it can be said that the corner portion formed by assembling the three timbers also has sufficient strength.

Further, since the connecting fittings are provided with the connecting plates 9, 10, 11 for the braces, three braces can be hung from the connecting fittings, and the parts for attaching the braces are special. There is no need to prepare it.

FIG. 3 shows another example of the use form in which the above-mentioned two square metal fittings are used. Here, the two metal fittings A and B are viewed from the side. In the figure, the girder 31 and the beam 32 are arranged in an L shape, and the L of the upper connection fitting A is
While being held inside the character-shaped connecting frame 1, it is also held inside the L-shaped connecting frame 1 of the lower connecting fitting B. An upper column 33 is sandwiched between the pair of connecting plates 6 and 7 of the upper connecting fitting A so as to project therefrom, and a lower column is provided between the pair of connecting plates 6 and 7 of the lower connecting fitting B. 34 is sandwiched and projected. In this state, if you hit the nail,
The girder 31, the beam 32, the upper pillar 33, and the lower pillar 34 are vertical, horizontal,
It is placed and fixed in the upper and lower directions.

In the above embodiment, nails are used to fix the timber, but it goes without saying that wood screws, bolts, nuts and the like can be used.

[0018]

[Effect] As described above, according to the corner-piece connecting metal fitting of the present invention, it is not necessary to carve a tenon or a groove at the end of the square-piece.
Resource savings can be realized. In addition, the three square members can be easily assembled in the longitudinal, lateral, and height directions with sufficient strength.
