[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framing method for a wooden building and a plate structure fitting used for the method.

[0002]

2. Description of the Related Art Generally, when a wooden building is assembled, a fitting structure such as a tenon or a tenon is formed at a joint of the shafts, and the shafts are fixed to each other by fitting. Combining is performed.

[0003] However, in this method of assembling the shaft, it requires skill in processing the fitting structure and the like, and since the fitting itself is formed by processing the shaft material itself, it is not possible to prepare the fitting structure in advance, thereby shortening the construction period. It is difficult, it takes time to assemble the shaft at the construction site, and the strength of the joint of the shaft becomes relatively weak.

[0004] From such a viewpoint, for example, a special fitting structure in which a steel plate or a bar is inserted into a meat portion of a shaft has been devised, and is gradually being put to practical use.

[0005]

SUMMARY OF THE INVENTION The present invention employs a novel fitting structure which replaces the conventional one, and requires a relatively short skill, requires a short construction time, requires less labor, and has a shaft assembly capable of obtaining sufficient bonding strength. The purpose is to be able to do it.

[0006]

In order to achieve the above object, according to the present invention, a frame structure of a wooden building is constructed by assembling a square cross-section wooden shaft member such as a column, a beam, a girder, a barb, a bundle, or the like. At this time, a plate structure fitting having a fitting portion fitted around the shaft member so as to surround four, three or two sides thereof and fastened with a fixture such as a nail or a bolt nut is used. Thus, the shaft members are fixedly connected to each other.

[0007] At this time, the plate-structured fitting is constructed by assembling a metal plate as a base, and in order to be inexpensive and corrosion-resistant, the metal plate is made of a steel plate and is entirely galvanized. Is good.

In the above-mentioned frame assembly, the fixing process of the shaft connecting portion is appropriately performed with a nail or the like in addition to the above, and finally, after the vertical level of the entire frame structure is accurately adjusted,
Perform full-scale fixing. The bracing is formed by fixing a band plate or a round bar with a turn buckle between the plate structure fittings by welding or the like.

The present invention is not limited to the above embodiment,
The use of a plate-structured joint at a part of a shaft member such as a column, a beam, a girder or the like which is joined to the shaft is also included in the category.

In order to fix a finished plate or the like, a relatively large through hole p as shown in FIG. 1 is provided on the locking surface covering the peripheral surface of the shaft material in each plate structure fitting. Spaces for nail holes are formed as necessary.

[0043]

According to the present invention constructed as described above, the plate-structured joint can be formed separately and ahead of the shaft, and the length of the shaft is simply reduced by using the standard material. Is only required to cut to a specific size, making it possible to create a fitting structure for joining shaft materials relatively easily and with a shorter construction period. Since the outer periphery of the end portion of the shaft is fitted to the relatively large fitting portion, the work content is simplified, the work efficiency is improved, and the coupling strength between the shafts can be increased. I can do it.

According to the plate structure fitting of the third aspect, the plate structure fitting is inexpensive and excellent in corrosion resistance, and contributes to the economy and durability of the frame structure.
