Description

  The present invention relates to a joining structure and joining apparatus for wooden members that join two wooden members for construction, such as beams and girders, through pillars and second-floor beams, foundations and pillars, to each other at joint surfaces.

Conventionally, as a joining structure of this kind of wooden member, for example, as shown in Patent Document 1 (see FIG. 1 and FIG. 2), the wooden member is attached so as to extend horizontally with respect to a girder standing up and down. Insert a pipe-shaped holder into the through-hole that penetrates in the width direction of the beam material, insert the bolt member into the insertion hole that extends in the beam material direction provided in the girder, and screw the tip of the bolt member to the screw of the pipe-shaped holder What is firmly attached by screwing into a hole is disclosed. The pipe-shaped receiving member is cut to a length corresponding to the thickness of the wood to be fastened, and a small hole is formed at the planned drawing position at the center of the side wall, and the bolt escapes from the side wall opposite to the planned drawing position. After forming a hole and drilling so that the edge of the small hole is pushed into the inside of the pipe member to form a cylindrical part that protrudes to the inside of the pipe member, a screw groove is provided on the inner wall of the cylindrical part to provide a female screw It is what. This connection structure has an advantage that the material of the wood can be enjoyed when viewed from the outside since both the pipe-shaped receiving member and the bolt member are embedded in the wooden member and cannot be seen from the outside. Furthermore, when performing pre-cut processing in which a pipe-shaped support is attached to a beam material in advance at a processing plant, there is no protrusion of the metal fittings from the wooden material, so that wooden materials can be loaded compared to wooden materials with conventional metal fittings. Less space. Therefore, the great effect that the labor and cost of transporting the wooden material are greatly reduced can also be obtained. The joint structure of the same kind of wooden material is also disclosed in Patent Document 2.

The straight hole portion 26 has an inner diameter larger than the outer diameter of the bolt member 31, and the screw portion 33 of the bolt member 31 is screwed into the screw hole portion 27.

  As shown in FIG. 7, the pipe member 21 has a cylindrical body 22 in which an engagement long hole 23 is processed, and an attachment hole member 25 is inserted from one end side in the axial direction, and one end side thereof is cylindrical. It is formed by slightly protruding from one end side of the main body 22 and fixing the outer periphery of the protruding portion to one end of the cylindrical main body 22 by welding 28. The pin member 29 is cylindrical, has one end side provided with a thread groove on the outer peripheral surface, and has an oval cross-sectional shape in which the one end side 29a is slightly crushed in one radial direction. The bolt member 31 has a hexagonal head 32 at one end, and is provided with a screw portion 33 in a predetermined range on the other end side.

  Next, formation of the joining structure of the beam member 11 and the beam member 16 will be described. The pipe member 21 is slidably inserted into the insertion hole 17 of the beam member 16, and a rod-like pin member 29 is inserted into the through hole 18 provided on the side surface of the beam member 16 and penetrates the engagement long hole 23. To the beam 16. Thereby, the pipe member 21 is restrained by the pin member 29 engaged with the engagement long hole 23, and can be slid in the longitudinal direction within the length range of the engagement long hole 23. It becomes the state accommodated in. Thereafter, the bolt member 31 is inserted into the attachment hole 12 of the girder 11 from the side surface 11 a side, the head 32 is engaged with the attachment port 13 via the washer 34, and the screw portion 33 is screwed into the screw hole portion 27.
