Description

  The present invention relates to a structure for connecting wood materials such as pillars and foundations, pillars and beams, beams and girders, and a connecting method thereof.

  Wood materials, for example, pillars and foundations, pillars and beams, beams and girders, etc. are connected to various connecting structures 101, 111, 121, so-called joints and joints as shown in FIGS. Each of the wood materials 102, 103, 112, 113, 122, 123 is formed in advance on the end face or the side face and connected to each other. Various metal parts are assembled to these connecting portions to reinforce the connecting structure.

For example, in a strip-shaped member 131 as shown in FIGS. 6A and 6B, this metal piece is arranged over both wooden materials 142 and 143, and nails 132 and the like are driven in the vicinity of both ends, thereby both wooden materials. 142 and 143 are connected.
7A and 7B, a fixed plate 152 is provided at one end, and a fan-plate-shaped member 151 in which a shaft-shaped member 153 is extended, as shown in FIG. The fixing piece 152 is fixed by a bolt 171 and a nut 172 that pass through one wood material 161, and the shaft-like member 153 passes through the other wood material 162, and the nut 155 is screwed to the male screw portion 154 at the end thereof. In this way, it is fixed and connected. By using such a member, the connection state of the wood materials is reinforced to improve the joint strength.

  However, in the connection structure of the above-described conventional wooden materials, depending on the shape of the joint or joint that connects the wooden materials, a structure that fits together, for example, a joint structure such as a seat sickle joint as shown in FIG. Thus, the yield strength in the pulling direction can be obtained, and the strength can be improved by using the reinforcing member as described above, but when the external force in the pulling direction increases, even if these reinforcing members are provided, For example, in the strip-shaped member described above, the fixing member such as each nail is bent inside the wooden material, sunk into the wooden material, or the fixing member comes off, and even if a large number of nails are used, There is a risk that both wooden materials will be separated. In addition, even in the case of the above-described wing plate-like member using a bolt, the bolt penetrating the wooden material may be bent, and inside the wooden material, it is embedded in the wooden material over the entire length of the bolt. In this case, the joint portion between the wood materials is separated, and in the worst case, the connection state between the wood materials may be destroyed.

  Further, in the above-described connecting structure, the strip-shaped member has a large number of man-hours such as driving a large number of nails, and the nails to be placed bear the strength in the pulling direction between the wooden materials. It is essential to place a predetermined number of these positions, and in addition, in the battledore member, holes for penetrating the bolts must be formed in both wooden members, and workability was not good.

  Therefore, in order to solve the above problems, the present invention can easily obtain the reinforcing structure as a connecting structure between wooden materials such as columns and beams, beams and girders, and reliably pull out the wooden materials. It aims at providing the connection structure of the wooden materials which can improve the yield strength of.

The part 11 is inserted and connected by the connecting body 9 (19). The connecting body 9 (19) extends over both the wood materials 1 and 2 along the outer surface of the wood materials 1 and 2, and the connecting body. 9 (19), since the outer peripheral surface of the fitting portion 11 is in contact with the inner peripheral surface of the circular recess 5, an external force (pulling force) acting in the direction in which the two wood materials 1 and 2 are separated is applied. In this case, the external force is received by the circular recess 5 and the insertion portion 11 of the wood material, that is, the insertion portion 11 fixed to the connecting body 9 (19) with respect to the external force in the pulling direction between the wood materials 1 and 2, The connected state is maintained by the circular recess 5, which is different from that of conventional thin screws and nails. Since the bite into the wood materials 1 and 2 is widened in the direction in which the external force works and is received by the surface, the indentation length is reduced, and the wood materials 1 and 2 are not easily cracked. Will be improved. And the connection state of the wood materials 1 and 2 is not greatly separated, and is not easily separated.
