Description

  The present invention relates to a construction wood connecting bracket for connecting a building wood and a construction element such as another wood or a joint fitting.

  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).

  By the way, when a large external force is applied to the frame structure in which the reinforcing wood is assembled as described above due to, for example, an earthquake, a large shear is applied to the connecting portion between the reinforcing wood and the vertical member and the connecting portion between the reinforcing wood and the cross member. Power will be generated.

  If the connecting portion between the reinforcing wood and the longitudinal and cross members does not have a sufficient connection rigidity against the shearing force generated in the connecting portion, the reinforcing effect by the reinforcing wood cannot be exhibited. A strong connection structure is required for the connecting portion between the timber and the vertical member and the connecting portion between the reinforcing timber and the cross member.

A mounting hole (not shown) for inserting and fixing the anchor bolt 14 is formed through the upper surface contact plate 34 that contacts the upper surface of the building foundation 12, and the upper surface contact. The connecting plate portion 35 having the same configuration as the connecting plate portion 6 of the first embodiment is projected on the outer plate surface of the plate 34, and the axial force transmission fitting 15 is connected to the connecting plate portion 35 using a connecting bolt 28. The overlapping connecting plate portion 16 can be connected (friction bonded).

  Thus, according to the truss structure configured using the vertical member connecting bracket B of the present embodiment and the cross member connecting bracket A of the first embodiment, when an external force is applied to the building due to an earthquake or the like, the beam member 1 is moved in the horizontal direction. A shearing force is generated to cause the lateral member connecting bracket A to be displaced with respect to the peripheral surface portion of the beam member 1 due to the force to move it. The embedded portion 5 firmly supports the shearing force and strongly resists the positional deviation.

  Then, from the connecting plate portion 6 of the cross member connecting bracket A which is not displaced, to the overlapping connecting plate portion 16 of the axial force transmission fitting 15 provided at one end portion of the wood 2A existing above the rectangular frame structure W, That is, the shear force is transmitted to the wood 2A provided with the axial force transmission fitting 15, and this shear force is converted into an axial force (tensile axial force or compression axial force) that moves the wood 2A in the direction of the material axis. Will change.

  Further, the axial force acting on the wood 2A is obtained from the connection plate 16 of the axial force transmission fitting 15 provided at the other end of the wood 2A, to the connection plate of the vertical member connection fitting 4B provided on the peripheral surface portion of the column member 1. Shear is transmitted to the portion 6, that is, to the column member 1 provided with the vertical member connecting bracket 4 </ b> B, and this axial force causes the vertical member connecting member 4 </ b> B to be displaced from the peripheral surface portion of the column member 1. Although the force changes, the embedded portion 5 of the vertical member connecting metal fitting 4B is positioned in the embedded hole 4 of the pillar material 1, so that the embedded portion 5 firmly supports the shearing force and resists misalignment. Therefore, this shearing force is supported by the pillar material 1.

  In addition, when an external force such as an earthquake causes a force to move the beam 1 in the horizontal direction, a force that causes the column 1 to tilt in conjunction with this acts on the peripheral surface of the column 1. 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 1 as described above, the shearing force is below the rectangular frame structure W. This axial force is transmitted to the foundation connecting bracket 33, that is, the building foundation 12 provided with the foundation connecting bracket 33, and this axial force is further applied to the foundation connecting bracket 33. Although it changes to a shearing force to be displaced with respect to the upper surface portion of the building foundation 12, the embedded portion 5 (anchor bolt 18) of the foundation connecting bracket 33 is embedded and fixed in the building foundation 12 and positioned. As a result, the embedded portion 5 firmly supports the shearing force. Therefore, this shearing force is supported by the building foundation 12.

  As described above, the shearing force and the axial force are satisfactorily transmitted between the building wood 1 and the wood 2A, so that the reinforcing action by each wood 2A is sufficiently exhibited and the deformation of the rectangular frame structure W is suppressed. It will be.
