Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a square timber connecting fitting for assembling square timbers such as columns, beams and girders.

[0002]

[Prior art]

 In wooden construction, in order to assemble square timbers such as columns, beams and girders, we worked by carving mortises and grooves on the ends of the timbers to combine the tenons and grooves. In addition, after assembling the timbers, the combined parts were sometimes reinforced with metal fittings.

[0003]

[Problems to be solved by the device]

 Thus, in the past, the end of the timber was worked to assemble the timber, but in this case, a longer timber is prepared at the sawmill, and the timber is shortened to an appropriate length according to the work. However, there are many parts of the timber that are wasted, which is not desirable in terms of saving resources. Moreover, the work of square timbers required skill and could not be performed easily. Furthermore, 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 square timber connection fitting, thereby realizing resource saving and enabling easy assembly of the square timber with sufficient strength.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, an L-shaped connecting frame composed of an L-shaped flat plate portion and two side plate portions bent from each end of the flat plate portion into an L-shape. And a pair of opposing connecting plates projecting at intersections of respective sides of the L-shape on the flat plate portion, and a plurality of holes are formed in each side plate portion of the L-shaped connecting frame and each connecting plate. Each is provided and configured.

[0006]

[Action]

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

[0007]

【Example】

 An embodiment 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 member connecting fitting according to the present invention. In the figure, the L-shaped connection frame 1 has a U-shaped cross section, and has an L-shaped flat plate portion 2 and two side plate portions 3 hanging from each end of the flat plate portion 2. , 4 and. A plurality of holes 5 are provided in these side plate portions 3 and 4.

On the flat plate portion 2 of the L-shaped connection frame 1, a pair of opposing column connecting plates 6 and 7 are provided in a protruding manner. 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 connecting frame 1, two brace connecting plates 9 and 10 are provided so as to project along the respective sides of the L-shape. Further, another brace connecting plate 11 is provided at a portion on the inner side of the corner of the L-shaped connection frame 1, that is, 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 usage form of the above-mentioned square bar connection fitting, and here, the connection fitting is viewed from above. In the figure, the L-shaped connection frame 1 has the bases 21 and 22 arranged in an L-shape and held inside. In addition, a pillar 23 is sandwiched between the pair of pillar connecting plates 6 and 7 and is projected. In this state, a plurality of nails are driven through the plurality of holes 5 formed in the side plate portions 3 and 4 of the L-shaped connection frame 1 and the plurality of holes 8 formed in the column connecting plates 6 and 7. Then, the bases 21, 22 and the pillar 23 are arranged in the longitudinal, lateral and height directions, assembled and fixed.

Since three pieces of timber can be assembled in this manner, 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, thereby 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 part formed by assembling three timbers also has sufficient strength.

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

FIG. 3 shows another example of the form of use in the case of using the above-mentioned two square metal fittings, in which the two metal fittings A and B are viewed from the side. In the figure, the girders 31 and the beams 32 are arranged in an L-shape and are held inside the L-shaped connection frame 1 of the upper connection fitting A, and the L-shaped connection frame of the lower connection fitting B. It is also held inside 1. An upper pillar 33 is sandwiched between the pair of connecting plates 6 and 7 of the upper connecting fitting A so as to project, and a lower portion is provided between the pair of connecting plates 6 and 7 of the lower connecting fitting B. A pillar 34 is sandwiched and is provided so as to project. In this state, if a nail is driven in, the girder 31, the beam 32, the upper column 33, and the lower column 34 are arranged and fixed in the vertical, horizontal, upward, and downward directions.

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

[0017]

【effect】

 As described above, according to the corner-piece connecting fitting according to the present invention, it is not necessary to carve a tenon or a groove at the end of the corner piece, so that resource saving can be realized. Also, the three square members can be easily assembled in the longitudinal, lateral, and height directions with sufficient strength.
