Description

  The present invention relates to a connecting structure of building wood for connecting a long building wood and a building element such as another wood or a building foundation.

  In the wooden frame construction method, struts are installed and fixed at diagonal positions of a rectangular frame structure formed by vertical members such as columns and cross members such as beams, or slanted between vertical members and cross members. The rectangular frame structure is reinforced to prevent deformation by installing and fixing a material (truss material).

  In addition, the method of fixing the reinforcing wood such as streaks and diagonals to the rectangular frame structure is to form a notch that fits the end of the reinforcing wood on the side of the vertical or horizontal member. The end of the reinforcing wood is fitted to the base and fixed by nailing or the like.

  However, in the case of wooden construction, if the reinforcing wood is fixed in a relatively simple direction such as nailing, there is a risk that the root will come off when a tensile force is applied to the reinforcing wood.

  Therefore, in recent years, a method of firmly fixing a reinforcing wood to a vertical member or a cross member using a hardware has become mainstream (see, for example, Patent Document 1).

If the building wood 1 is connected to the building element 3 of the rectangular frame structure W of the frame as a reinforcing material such as a brace material or a truss material, the axial force acting on the building wood 1 is applied to other elements such as columns and beams.

That is, the shearing force is transmitted to the building wood 1 provided with the axial force transmission fitting 2, and this shearing force causes the building wood 1 to move in the material axis direction (tensile axial force). (Or compression axial force).

  Further, the axial force acting on the building wood 1 is generated from the overlapping connecting plate portion 10 of the axial force transmission fitting 2 provided at the other end of the building wood 1 and the vertical member connecting fitting provided on the peripheral surface portion of the column member 3A. This is transmitted to the connecting plate portion 9 of 4B, that is, to the column member 3A provided with the vertical member connecting bracket 4B, and this axial force causes the vertical member connecting bracket 4B to be displaced with respect to the peripheral surface portion of the column member 3A. However, since the embedded portion 12 of the vertical member connecting bracket 4B is positioned in the embedded hole 13 of the column member 3A, the embedded portion 12 firmly supports the shear force and is displaced. Therefore, this shearing force is supported by the column member 3A.

  In addition, when a force to move the beam 3A in the horizontal direction is applied due to an external force such as an earthquake, a force is applied to the column 3A to be tilted in conjunction with this, and against the peripheral surface portion of the column 3A. As a result, a shearing force is generated to displace the vertical member connecting bracket 4B. However, since the vertical member connecting bracket 4B is not displaced relative to the column member 3A as described above, the shearing force is below the rectangular frame structure W. The axial force of the building wood 1 is transferred to the foundation connecting bracket 4C, that is, the building foundation 3B provided with the foundation connecting bracket 4C, and this axial force is further transmitted to the foundation connecting bracket. It changes to a shearing force that attempts to shift 4C relative to the upper surface of the building foundation 3B, but the embedded portion 12 (anchor bolt 18) of the foundation connecting bracket 4C is embedded and fixed in the building foundation 3B and positioned. This embedded part by Since 12 strongly supports the shearing force and strongly resists displacement, the shearing force is supported by the building foundation 3B.

  In this way, the shearing force and the axial force are satisfactorily transmitted between the building element 3 and the building wood 1, so that the reinforcing action by each building wood 1 is sufficiently exhibited and the rectangular frame structure W is deformed. Will be suppressed.

When the drift pin 6 is driven and inserted into the pin insertion hole 25 from the side of the column member 3A through the communicating pin locking hole 21, the drift that crosses through the embedded portion 12 through the pin locking hole 21 is inserted. The pin 6 has a structure in which the embedded portion 12 is prevented from coming off and locked in the embedded hole 13 (the column base portion connecting bracket 4D is fixed to the lower portion of the column member 3A). At this time, the connecting plate portion 9 protrudes from the side portion of the embedding hole 13 to the side of the wood 3A.
