[0005] An object of the present invention is to provide a composite wooden structure in which connecting members can be easily and firmly joined to wooden members. [Means for solving the problem]

[0006] The first invention of the composite wooden structure (for example, composite wooden structures 1, 1A, 1B, 1C, 1D, 1E, and 1F described later) is a composite wooden structure comprising wooden members (for example, wooden beams 20, wooden louvers 51, wooden treads 63, wooden walls 71, and wooden beams 80 described later) and other members (for example, posts 11, horizontal members 50, diagonal members 62, reinforced concrete beams 70, and reinforced concrete slabs 81 described later), and the wooden members, the other members, and The wooden member is provided with a connecting member (e.g., connecting member 30, 30A described below) that connects the wooden member to the other member, a hole (e.g., hole 21 described below) is formed in the wooden member, the connecting member is provided with a steel pipe (e.g., steel pipe 31 described below) that is fixed to the other member and inserted into the hole in the wooden member, and an adhesive (e.g., adhesive 34 described below) is filled in the gap between the hole in the wooden member and the steel pipe.

[0007] According to this invention, a composite wooden frame is constructed by connecting wooden members and other members with connecting members having steel pipes and rod-shaped members. Specifically, adhesive is applied to the outer surface of the steel pipe, and then the steel pipe is inserted into the hole in the wooden member. This allows the connecting member to be easily and firmly joined to the wooden member, integrating the wooden member with other members. This increases the strength and stability of the entire wooden composite frame.

[0008] The wooden composite structure of the second invention is characterized in that the connecting member further includes a rod-shaped member (e.g., pin 32 described below) that penetrates the wooden member and the steel pipe when the steel pipe is inserted into the hole.

[0009] According to this invention, the connecting member is provided with a rod-shaped member that penetrates the wooden member and the steel pipe. Therefore, with the steel pipe inserted into the hole in the wooden member, the rod-shaped member is driven into the wooden member from the outside, penetrating the wooden member and the steel pipe. This more firmly joins the connecting member to the wooden member, thereby more firmly integrating the wooden member with the other member.

[0010] A third aspect of the present invention provides a composite wooden structure, wherein the other members are made of steel, and the steel pipes of the connecting members are fixed to the other members with connecting fittings.

[0011] According to this invention, the other members are made of steel, which ensures the strength of the other members. Furthermore, the steel pipes of the connecting members are fixed to the other members with connecting metal fittings, which allows the connecting members to be easily and firmly fixed to the other members. This further increases the strength and stability of the entire wooden composite frame.

[0012] A fourth aspect of the present invention is a composite wooden structure, characterized in that the interior of the steel pipe is filled with mortar or concrete.

[0013] According to this invention, the steel pipes are filled with mortar or concrete, which increases their rigidity and improves the joint strength between the wooden members and other members via the connecting members, resulting in a stronger and more stable composite wooden structure. [Effects of the Invention]

[0014] According to the present invention, a composite wooden structure can be provided in which connecting members can be easily and firmly joined to wooden members. [Brief explanation of the drawings]

[0016] The present invention relates to a composite wooden structure comprising a wooden member and another member. Specifically, adhesive is applied to the outer surface of a steel pipe extending from the other member, and the steel pipe is inserted into a hole formed in the wooden member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the embodiments, the same components will be denoted by the same reference numerals, and the description thereof will be omitted or simplified. [First embodiment] FIG. 1 is a front view of a composite wooden structure 1 according to a first embodiment of the present invention. The wooden composite frame 1 is gate-shaped and comprises a pair of bases 10 installed on a floor surface 2, a pair of support columns 11 extending upward from the bases 10 as other members, and wooden beams 20 as wooden members extending horizontally between the upper ends of the support columns 11. The wooden beams 20 and the support columns 11 are connected by connecting members 30.

[0017] Fig. 2(a) is an enlarged cross-sectional view of a portion of the composite wooden structure 1 surrounded by a dashed line A. Fig. 2(b) is a cross-sectional view of the composite wooden structure 1 of Fig. 2(a) taken along line BB. A hole 21 extending in the length direction is formed on both end surfaces of the wooden beam 20, and a through-hole 22 is formed penetrating the hole 21. The depth of the hole 21 is, for example, 50 mm or more and 200 mm or less. The connecting member 30 comprises a steel pipe 31 whose base end is fixed to the support 11 and whose tip end is inserted into a hole 21 in the wooden beam 20, and a pin 32 which is a rod-shaped member that fixes the steel pipe 31 to the wooden beam 20.

[0018] The support 11 is a single steel pipe, and the base end side of the steel pipe 31 of the connecting member 30 is fixed to the support 11, which is a single steel pipe, by an orthogonal clamp 12 serving as a connecting metal fitting. A through hole 33 perpendicular to the axial direction of the steel pipe 31 is formed at the tip end of the steel pipe 31. The tip end of the steel pipe 31 is inserted into the hole 21 in the wooden beam 20, and in this state, a pin 32 is inserted into the through hole 22 in the wooden beam 20 and the through hole 33 in the steel pipe 31. An adhesive 34 is filled in the gap between the hole 21 in the wooden beam 20 and the outer peripheral surface of the tip end of the steel pipe 31 and has hardened. The gap between the hole 21 in the wooden beam 20 and the outer peripheral surface of the tip end of the steel pipe 31 is, for example, about 0.5 mm to 1.0 mm.

[0019] The procedure for joining the connecting member 30 to the wooden beam 20 will be described below with reference to the flowchart of FIG. In step S1 , adhesive 34 is applied to the outer peripheral surface of the tip end of steel pipe 31 of connecting member 30 , and the steel pipe 31 is inserted into hole 21 of wooden beam 20 . In step S2, the pin 32 is attached to the wooden beam 20. That is, the pin 32 is inserted through the through hole 22 of the wooden beam 20 and the through hole 33 of the steel pipe 31. As a result, the pin 32 penetrates and engages the wooden beam 20 and the steel pipe 31, and the steel pipe 31 is fixed to the wooden beam 20. At this time, adhesive 34 is filled in the gap between the hole 21 of the wooden beam 20 and the outer peripheral surface of the tip side of the steel pipe 31.

[0020] According to this embodiment, the following effects are obtained. (1) A wooden composite frame 1 was constructed by connecting wooden beams 20 and posts 11 with connecting members 30 having steel pipes 31 and pins 32. Specifically, adhesive 34 is applied to the outer peripheral surface of the tip end of the steel pipe 31, and in this state, the steel pipe 31 is inserted into the hole 21 of the wooden beam 20. This allows the connecting member 30 to be easily and firmly joined to the wooden beam 20, integrating the wooden beam 20 and the support 11. This increases the strength and stability of the entire wooden composite frame 1. Furthermore, because adhesive 34 is filled between the steel pipe 31 and the hole 21, rattling of the steel pipe 31 can be prevented.

[0021] (2) The connecting member 30 is provided with a pin 32 that penetrates the wooden beam 20 and the steel pipe 31. Therefore, while the connecting member 30 is inserted into the hole 21 of the wooden beam 20, the pin 32 is driven into the wooden beam 20 from the outside, penetrating the wooden beam 20 and the steel pipe 31. This makes it possible to more firmly join the connecting member 30 to the wooden beam 20, thereby more firmly integrating the wooden beam 20 and the support 11.

[0022] (3) The support columns 11 are made of single steel pipes, ensuring the strength of the support columns 11. Furthermore, the steel pipes 31 of the connecting members 30 are fixed to the support columns 11 with orthogonal clamps 12, so the connecting members 30 can be easily and firmly fixed to the support columns 11. This further increases the strength and stability of the entire wooden composite frame 1.

[0023] Second Embodiment FIG. 4 is a front view of a composite wooden structure 1A according to a second embodiment of the present invention. This embodiment differs from the first embodiment in that the support posts 11 are wooden posts rather than single pipes. That is, wooden support 11 extends upward from base 10, and the base end of steel pipe 31 is fixed to this support 11. The joint structure between the base end of steel pipe 31 and wooden support 11 is the same as the joint structure between the tip end of steel pipe 31 and wooden beam 20. According to this embodiment, the same effects as those (1) to (3) above are obtained.
