A relatively large number of framed structures in a wooden building such as a wooden two-story or three-story house are connected or connected to a central area between fulcrums of the girders or an inter-column suspension area. In general. Such a joint part of the girder / small beam is arranged in a relatively narrow area, and the joining operation of the joint part has to be performed in a limited narrow working area, so that it is simple or simple. It is actually desirable to apply a girder / small beam joint construction method using various joining means. However, the conventional metal joint has a structure in which a relatively large number of bolts, pins, nails, or the like must be used. It is difficult to apply as a joining means for joining. In addition, in many wooden buildings that emphasize the degree of freedom of floor plan or floor plan of each floor, or the functionality of each floor space,
The layout or layout of the columns and walls of the lower and upper floors does not match or match each other, and therefore, inconsistencies or inconsistencies in the relative positions of the columns and the like on each floor can generally occur. For this reason, as a pillar-base supporting form of the pillar of the upper floor seen in a relatively large number of wooden buildings, the pillar-base is supported in the central area between the fulcrums of the girders of the lower floor or the pillar-suspended area.

[0005] In particular, floor plans or architectural plans of wooden buildings are generally substantially modular in measure or in-between dimensions, so that the girders, the girders and the upper floors. As a result of the column cores crossing or intersecting at the same position, the joint portion of the large beam and the small beam easily coincides with the column base of the column on the upper floor in a planar manner. In such a girder / small beam / column base joint construction method, the girder / small beam joint structure and the girder / column base joint structure are constructed at the same position or the same location in the central region between the fulcrum points of the girder. Inevitably, as a result, the mutual interference between the metal joints complicates or complicates the construction of the joint portion, or complicates the joint operation process. Therefore, the girder / small beam /
In the joint structure of the column base, it is difficult to use the conventional wood joining hardware, and it is possible to join the framed structural members by a conventional wood joining method using a connection and a nail which has been widely used for many years. Only.

The present invention has been made in view of the above points, and an object of the present invention is to simplify a joint structure of a girder and a girder in a region between fulcrums of the girder,

A vertical side wall 31 that can be aligned with the formed vertical groove 11 is provided to enable the work of hooking the end D1 to the beam supporting member 1 or the centering operation of the beam D by the chin resting operation.

It should be noted that the present invention is not limited to the above embodiment, and various modifications or changes can be made within the scope of the present invention described in the appended claims. Needless to say, they are included in the scope of the present invention. For example, in the above embodiment, the through-hole 26 formed in the arm member 21 of the small beam support 1 is used.
Can be formed in the horizontal substrate 6 of the column base supporting hardware 5. Thereby, it is possible to drive a fastener such as a nail or a screw into the upper surface of the girder B through the through hole 26 and the through hole of the horizontal substrate 6.

FIG. 8 is a perspective view illustrating a joint structure of a girder and a girder using the girder support shown in FIG. As shown in FIG. 8, the small beam support 1 can be suitably used as a joint between the large beam B and the small beam D at a joint portion between the large beam B and the small beam D which is not related to the column base of the upper floor. . In such a joint structure, the small beam support 1 is directly mounted on the upper surface of the large beam B. An engaging tool N such as a nail is driven or screwed into the through holes 26, 27, 35 (FIG. 2), and the small beam support 1 is fixed to the large beam B. Similarly to the above embodiment, the end D1 of the small beam D is
Is dropped into the opening region of the small beam support 3 at a position aligned with the left and right vertical side walls 31 of the small beam support 3, and is hooked on the small beam support 3. Thus, the small beam D is connected or connected to the side surface of the large beam B at the small beam support 1, and is supported by the large beam B via the small beam support 1.

According to the above construction of the present invention, the joining structure of the girder and the small beam in the region between the fulcrum points of the girder is simplified, and the girder, the small beam and the column base are provided at the same position in the region between the fulcrum points of the girder. Can be provided by a relatively simple or simple operation.
Moreover, according to the above configuration of the present invention, a wooden structure which can exert a restraining force or a supporting force of a column base portion against a short-term load such as an earthquake load or the like, and can simplify or shorten a construction work process of an upper story column. It is possible to provide a joint structure of a building.
