2. Description of the Related Art In wooden constructions, columns and beams have been connected to each other for a long time, but in recent years, connecting fittings have been used. Further, when a thin material is used in the framing method, a connection fitting is used in order to secure a connection strength by minimizing a cut of a thickness cross section in a direction orthogonal to the length direction. Such connecting fitting, cross bolts and formed with external threads at its opposite ends, one end being a Bian flat portion of battledore shape, such as a battledore male screw is formed a bolt is used at the other end.

In the case of using the above-described crossover bolt, a washer and a nut must be inserted and screwed into the external threads at both ends. Therefore, a bolt insertion hole or a bolt insertion hole is provided in a connecting column and beam, and a bolt is inserted. A recess is provided in the beam that communicates with the insertion hole and accommodates the washer and nut,
After the bolt is inserted through the bolt insertion hole and the bolt insertion hole, a male screw is inserted into the washer in the recess, and a nut is screwed into the male screw, thereby connecting the column and the beam.

An inclined surface 72 s is formed and fits inside the outer ring 71.

Next, an example of connecting a column and a beam will be described. First, the outer ring 71 is fitted into the annular groove 43 located on the left side of the positioned pillar 41 so that the inner peripheral surface of the pillar 41 is closed toward the pillar 41, and the annular groove 55 of the left beam 51 is fitted.

Next, the outer ring 71 is fitted into the annular groove 43 located on the right side of the column 41 so that the inner peripheral surface is closed and closed toward the column 41, and the inner ring 72 is inserted into the annular groove 55 of the right beam 51. After the outer ring 71 is fitted so as to expand toward the beam 51, the inner ring 72 is fitted into the outer ring 71.

Then, a tool is inserted into the wedge insertion hole 53 of the left beam 51, the shaft 1 shifted to the left is moved to the right, and the head 3 is positioned in the left and right wedge insertion holes 53. The wedge member 11 is inserted into the left and right wedge insertion holes 53 with the engagement groove 12 positioned above the small-diameter portion 2 and the two ends of the engagement groove 12 with the thinner wall facing downward. Next, the small-diameter portion 2 is driven into the engagement groove 1 by driving the wedge member 11 using a tool.
2 and the thickness of both ends of the engaging groove 12 is sequentially increased upward, so that the right and left beams 51 move toward the column 41 as the amount of driving of the wedge member 11 increases. At the same time, the left and right beams 51 are connected to the column 41 by securely fitting the inner ring 72 to the outer ring 71.

Since the engaging groove 12 has a wedge shape, the wedge member 11 sandwiches the small diameter portion 2 and expands slightly to be in pressure contact with the inner periphery of the wedge insertion hole 53. Also, the wedge member 1
The collar 31 is pushed by the wedge member 11 onto the inclined surface 2 s as the amount of driving 1 increases, so that the peripheral wall is
By expanding along s, the gap between the shaft 1 and the left and right beams 51 is almost filled, and the shaft insertion hole 52 between the column 41 and the wedge insertion hole 53 is divided.

When the adhesive is filled from the filling hole 54 in a state where the shaft insertion hole 52 between the column 41 and the wedge insertion hole 53 is divided by the collar 31, the adhesive is filled between the two collars 31. The space, that is, the shaft insertion hole 52, the filling hole 54, and the recesses 44 and 56 are filled, and the column 41 and the left and right beams 51 are bonded. Then, the wooden plug 61 is used to insert the wedge insertion hole 5.

When the wedge member 11 is engaged with the head 3 of the shaft 1, the column 41 and the beam 51 are formed.
Can be connected to each other, so that no special skill is required for the connecting operation, and the connecting operation can be made simple and easy.

Further, the wedge member 11 is inserted and driven,
Since the engagement groove 12 may be engaged with the head 3 of the shaft 1, the beam 51 is formed by reducing the wedge insertion hole 53 of the beam 51, that is, by reducing the loss of the thickness cross section.
And the connection strength can be ensured by positioning the shaft 1 at the center of the beam 51. Since the surface of the head 3 on the side of the small-diameter portion 2 is spherical, even if the shaft insertion hole 52 and the wedge insertion hole 53 are not orthogonal to each other, that is, the shaft insertion hole 52 and the wedge insertion hole 5
Since it is sufficient that 3 intersects at an angle within a certain range, the machining accuracy of the shaft insertion hole 52 and the wedge insertion hole 53 can be made rough, and the range of use of the wood member connecting tool can be widened.

Since the engaging groove 12 is wedge-shaped, the wedge member 11 sandwiches the small-diameter portion 2 and expands slightly to be pressed against the inner periphery of the wedge insertion hole 53, thereby forming a wedge member. 11 does not fall off, and the connecting force can be maintained. Furthermore, since the wedge member 11 has a spring action, the engagement state with the shaft 1 is hard to be released, and a good connection state can be maintained. And since the wood member connecting tool can be embedded in the pillar 41 and the beam 51, the wood member connecting tool is not exposed at the time of connection, and the appearance is good.

Further, since the adhesive can be concentrated on the portion contributing to the connection by the collar 31, a good connection strength can be obtained with a small amount of the adhesive. In addition, even if two sets of wood member connecting tools are used for connection at one location, the wedge member 11 may be inserted and driven in so that the engaging groove 12 is engaged with the head 3 of the shaft 1. Work is easier and easier than before.

As described above, according to the present invention, the wood member need only be cut and round-hole-processed, so that it can be easily processed without requiring any skill, and the number of processing machines can be reduced. In addition, the tool cost can be reduced, and wood can be effectively used by reducing waste materials. Also, since the wood member can be connected by engaging the wedge member with the head of the shaft, no special skills are required for the connection work,
The connecting operation can be made simple and easy.

Further, since the engagement groove of the wedge member only needs to be engaged with the head of the shaft, the wood material is reduced by reducing the wedge insertion hole provided in the wood member, that is, by reducing the loss of the cross section of the thickness. The strength of the member can be secured, and the connection strength can be secured by positioning the shaft at the center of the wooden member. In addition, since the wooden member connector can be embedded in the wooden member, the wooden member connector is not exposed at the time of connection, and the appearance is good.

Since the adhesive can be concentrated on the portion contributing to the connection by the collar, good connection strength can be obtained with a small amount of the adhesive.
