As described above, there are known one-slit type and two-slit type as conventional beam receivers, but most of them are two-slit types, and one-slit type is extremely rare. In the case of the two slit type, since it is necessary to form two slits 81 </ b> A in the beam 80, the number of processing steps for the beam 80 increases.
However, since most of the beam receivers are fixed to the column with bolts as described above, in the case of the one-slit type as shown in FIG. 23, the standing plate portion 52 and the fixing bolt 56 are positioned at the axial center position. When configured to come, the bolt 56 interferes with the upright plate portion 52. In order to avoid this interference, it is necessary to take measures such as decentering the bolt 56 from the shaft center or providing a notch 54 in the standing plate 52 to avoid interference with the bolt 56 as in the example of FIG. From these viewpoints, it is considered that the adoption of the 1 slit type is small.

  Further, as shown in FIG. 25, when another alignment beam 80C is disposed adjacent to the beam 80B joined to the column 70, the beam 80A is arranged perpendicular to the alignment beam 80C and joined to the column 70. If the bolt 58 that fixes the beam receiver 51 toward the mating beam 80C is to be penetrated, the bolt 58 interferes with the beam receiver 51 that receives the beam 80A, and thus cannot be joined. Further, even if it is attempted to connect the beam 80B joined to the column 70 and the adjacent beam 80C adjacent thereto with the bolt 59 penetrating in the width direction, the beam receiver 51 for receiving these beams 80B and 80C. The bolt 59 interferes with the upright plate portion 52. The interference between the receiving bolts 59 of the mating beams 80C is the same for the two-slit type. For this reason, it is necessary to use a conventional joint metal fitting or the like in a complicated manner.

An object of the present invention is to avoid interference with a bolt for fixing a column or a beam on a column, and to avoid interference with a bolt for joining a laminated beam, even though it is a 1-slit type in the connection of a wooden column / beam. It is to provide a beam receiver that can be performed with a simple configuration.
Another object of the present invention is to connect a wooden pillar / beam having a laminated beam by using a plurality of one-slit beam receivers having the same shape, and the beam receiver can have a simple structure. It is to provide a column / beam joint structure.
Still another object of the present invention is to connect the beam on the column and the beam to be abutted against it with a one-slit beam receiver, which can be performed with a simple configuration while avoiding interference with the bolt for joining the beam. It is to provide a joint structure of wooden columns and beams.

It is characterized by the fact that the bolt has been expanded to a position where it can penetrate.
In addition, the above-mentioned “carving” is also called “spotting”.

  According to this configuration, in a beam receiver having a standing plate portion inserted into the slit of the beam and a joining plate portion fixed to the column, a bolt joined to the column or the beam on the column is prevented from interfering with the standing plate portion. Since the notch to be formed is provided in the upright plate portion, interference of the bolt for joining to the column or the column beam can be avoided even though it is a one-slit type. Further, since the position of the tip of the notch is expanded to a position where the bolt for joining the beam can penetrate, interference with the bolt for joining the beam can be avoided. In addition, it is possible to avoid interference with the bolts for joining the mating beams simply by widening the tip position of the notch that avoids interference of the bolts for joining the pillar or the beam on the pillar. Can also be used for bolt interference avoidance. Therefore, it is not necessary to form a dedicated interference avoidance portion for each bolt, and the beam receiver has a simple configuration. As the tip position of the notch is widened, the notch can be used for bolt tightening work, and the degree of freedom in selecting a tool type for bolt tightening and a tightening method is increased.

  In this invention, it is desirable that the front end of the notch is on the front end side with respect to the center position of the lateral width of the upright plate portion. When the tip of the notch is on the tip side of the center position of the upright plate portion, the position of the bolt for joining is set to a general column beam when the notch interferes with the bolt for joining the laminated beam. This design can be avoided without changing the bolt position.
