  DESCRIPTION OF EMBODIMENTS Embodiments of a structure for joining members of a wooden building according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows an overall outline of a wooden building 100 that employs a member joining structure for a wooden building according to the present embodiment. In the present embodiment, the member joining structure according to the present invention is employed at the joint portion between the column 2 and the beam 3 of the wooden building 100 shown in FIG. The member joining structure according to the present invention is not limited to joining columns and beams, and can also be adopted when joining beams.

  Fig.2 (a) is sectional drawing of the member junction structure which concerns on this embodiment, (b) is a front view. As shown in the figure, the column 2 and the beam 3 are joined by the column / beam connecting bracket 1, fastening bolts 7 and 8, and components associated therewith.

  The column / beam connecting bracket 1 constitutes the structural material joint for building of the present invention, and is attached to the side surface of the column 2 and the lower end of the beam 3 formed integrally with the mounting plate 4. A receiving plate 5 and a reinforcing rib plate 6 which are integrally formed with the receiving plate and the mounting plate 3 to reinforce them.

  The beam 3 is provided with a fitting recess 18 that is sized to accommodate the column / beam connecting bracket 1. The column / beam connecting bracket 1 is integrated with the beam 3 in advance in a factory or the like. ing. Since the receiving plate 5 is housed in a notch that forms a part of the fitting recess 18, the surface thereof is flush with the lower surface of the beam 3 and does not protrude from the lower surface of the beam 3, so that the appearance is not impaired. .

  The reinforcing rib plate 6 has a plurality of pin holes 6a above it and a plurality of pin holes 6b below it. These pin holes 6a and 6b communicate with pin holes penetrating between the side surfaces of the beam 3, and the pins are connected and inserted to structurally integrate the column / beam connecting bracket 1 and the beam 3. .

  The mounting plate 4 is housed in a notch 19 provided on the side surface of the pillar 2 in substantially the same size and shape as the mounting plate. As a result, the surface is flush with the side surface of the column 2 and does not protrude from the side surface of the column 2.

  A plurality of bolt insertion holes 14 penetrating in the plate thickness direction and allowing the fastening bolts 7 and 8 to pass therethrough are arranged in the mounting plate 4 so as to communicate with the bolt insertion holes 20 provided in the pillar 2.

Fastening bolts 7 are inserted into the bolt insertion holes 14 and 20 on the beam back outer end side (upper and lower sides) of the beam 3 so that a dish-shaped bolt head comes to the opposite side of the mounting plate 4. And the side which opposes the mounting plate 4 is fastened by an inner nut 23 via a washer 22 outside the outer side of the mounting plate 4 by the nut 10.

  Further, an adhesive such as an epoxy resin is injected into the bolt insertion hole 20 at the outermost end, and the fastening bolt 7 is more firmly fixed to the column 2. Thereby, even if the compressive force of the bending moment works, the mounting plate 4 itself does not sink into one member. Further, even if a tensile force of a bending moment is applied, the bolt head is sunk into the side surface of the column 2 by the supporting pressure, and there is no fear that the mounting plate 4 is lifted from the side surface of the column 2.

  Since the fastening bolt 7, the inner nut 23, and the adhesive are injected at the factory before shipment, there is no problem such as a decrease in accuracy due to field work.
