[0005] , , ,

[0004] , , , , ,<000003​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The first invention is a wooden structure in which a pair of upper and lower wooden members are joined together (for example, wooden structure 1, wooden frame 1A, wooden structure 1B described later), wherein a first recess (for example, recess 20, first recess 60, 70 described later) is formed at the upper end of the lower wooden member (for example, wooden beam 2, wooden wall 53, lower wooden beam 51 described later), and the lower end of the upper wooden member (for example, wooden floor slab 3, upper wooden beam 52, wooden wall 53 described later) The part is characterized in that a second recess (for example, a through hole 24, second recesses 61, 71 described later) is formed opposite the first recess, the upper and lower ends of a connecting member (for example, connecting members 10, 10B described later) are inserted into the first recess and the second recess, and a filler made of grout or adhesive (for example, filler 30 described later) is filled into the gap between at least one of the first recess and the second recess and the connecting member.

[0007] According to this invention, a first recess is formed in the lower wooden member, and a second recess is formed in the upper wooden member. The upper and lower ends of the connecting member are inserted into the first and second recesses, and then a filler is filled into the gap between the recess and the connecting member to join the wooden members together and construct a wooden structure. This enables the creation of a timber structure in which timber members are firmly joined together. Furthermore, since the timber members are joined together with connecting and filling materials, joining the timber members together is relatively easy. In addition, this filling material has higher shear strength and shear rigidity than wood, which can improve the stability of the timber structure.

[0008] The wood structure of the second invention is characterized in that the connecting member (for example, the connecting member 10B described later) comprises a plate portion (for example, the plate portion 11 described later) interposed between the pair of wood members, a first locking portion (for example, the first locking portion 12 described later) extending from the plate portion and inserted into the first recess, and a second locking portion (for example, the second locking portion 13 described later) extending from the plate portion and inserted into the second recess, wherein the second locking portion is rod-shaped or plate-shaped.

[0009] According to this invention, since the connecting member is composed of a plate portion, a first locking portion, and a second locking portion, the wooden members can be firmly joined together by the connecting member.

[0010] The third invention relates to a wood structure characterized in that the lower wood member is provided with an injection hole (for example, an injection hole 23 described later) extending from the side surface of the lower wood member to the center of the first recess, and the filler is injected from the side surface of the lower wood member through the injection hole into the gap between the first recess and the connecting member.

[0011] According to this invention, an injection hole is provided from the side of the wood member to the center of the first recess, and the filler material is injected from the side of the lower wood member through this injection hole into the gap between the first recess and the connecting member. Therefore, the filler material can be filled without leaving any gaps between the first recess and the connecting member. Furthermore, since the injection hole is provided so as to reach the center of the first recess, the distribution of the filler material within the first recess can be made uniform when the filler material is injected. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a wood structure in which wood members can be joined together relatively easily. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0014] The present invention is a wooden structure in which a pair of upper and lower wooden members are joined. In the wooden structure, the upper wooden member and the lower wooden member are joined by a connecting member. The first embodiment and the third embodiment are wooden structures in which a wooden floor slab and a wooden beam are joined. The second embodiment is a wooden structure including a wooden column, a wooden beam, and a wooden wall. Hereinafter, embodiments of the present invention will be described based on the drawings. In the description of the following embodiments, the same reference numerals are given to the same constituent elements, and the description thereof is omitted or simplified. 〔First Embodiment〕 FIG. 1 is a longitudinal sectional view of a wooden structure 1 according to the first embodiment of the present invention. FIG. 2 is an A-A sectional view of the wooden structure 1 in FIG. 1. FIG. 3 is a B-B sectional view of the wooden structure 1 in FIG. 1. The wooden structure 1 includes a wooden beam 2 as a lower wooden member, and a wooden floor slab 3 as an upper wooden member attached to the wooden beam 2 with a connecting member 10.

[0015] The connecting member 10 is made of steel and has a cylindrical shape. A recess 20 as a first recess is formed at the upper end of the wooden beam 2. The inner diameter of the recess 20 is larger than the outer diameter of the connecting member 10 by a predetermined dimension. [[ID=三十三]] A small-diameter hole 21 is formed at the center of the recess 20. A through hole 22 extending linearly to the small-diameter hole 21 is formed on the side surface of the wooden beam 2. This through hole 22 is formed so as to become higher as it goes from the side surface of the wooden beam 2 toward the center of the recess 20.

[0016] These small-diameter holes 21 and through holes 22 constitute injection holes 23 extending from the side surface of the wooden beam 2 to the center of the bottom surface of the recess 20. The injection holes 23 are provided so that they become higher as they move from the side surface of the wooden beam 2 towards the center of the recess 20, but the injection holes are not limited to this arrangement and may be provided almost horizontally. At the lower end of the wooden floor slab 3, a through-hole 24 is formed as a second recess opposite to the recess 20. The inner diameter of the through-hole 24 is slightly larger than the outer diameter of the connecting member 10.

[0017] The lower end of the connecting member 10 is inserted into the recess 20. The upper end of the connecting member 10 is inserted into the through hole 24, and there is virtually no gap between the connecting member 10 and the through hole 24. A leak-stopping tape 25 and a fire-resistant covering material 26 are interposed between the wooden beam 2 and the wooden floor slab 3. As shown in Figure 3, the leak-stopping tape 25 is positioned to surround the recess 20, and this leak-stopping tape 25 forms the discharge hole 27. The gap between the recess 20 and the connecting member 10 is filled with grout material 30 through the injection hole 23.

[0018] For example, as shown in Figure 1, the connecting member 10 is a cylinder with a diameter of 52 mm, the depth of the recess 20 is 55 mm, the outer diameter of the first recess is 70 mm, the diameter of the injection hole is 5 mm, and the height of the discharge hole is 8 mm.

[0019] The procedure for attaching the wooden floor slab 3 to the wooden beam 2 will be explained below, referring to the flowchart in Figure 4. In step S1, recesses 20 and injection holes 23 are formed in the wooden beam 2, and through holes 24 are formed in the wooden floor slab 3 (see Figure 6). Specifically, as shown in Figure 5, a recess 20 and a small-diameter hole 21 are formed in the wooden beam 2 by counter-cutting with a hole saw (hole cutter) 40. Furthermore, as shown in Figure 6, a through hole 22 leading to the small-diameter hole 21 is formed by drilling from the side of the wooden beam 2 with a drill (not shown), which serves as the injection hole 23. In addition, a through hole 24 is formed in the wooden floor slab 3 by drilling.

[0020] The hole saw 40 comprises a drill 41 located at the center of rotation and a rotating blade 42 arranged in a ring shape around the drill 41. By attaching the hole saw 40 to the tip of an electric drill 43 and rotating it, the drill 41 drills a hole to position the hole saw 40, while the rotating blade 42 performs counterboring. Therefore, when the rotating blade 42 of the hole saw 40 performs counterboring, the drill 41 of the hole saw 40 incidentally forms a small-diameter hole 21 in the center of the recessed area 20, which is the counterbored portion. Generally, only the counterbore portion is needed, and the small diameter hole is unnecessary, so a wood filler is used in this small diameter hole. However, in this embodiment, the small diameter hole 21 is used as part of the injection hole 23, so the work of filling it with wood is unnecessary, improving construction efficiency.

[0021] In step S2, as shown in Figure 6, the wooden floor slab 3 is placed on the wooden beam 2. At this time, a leak-stopping tape 25 and a fire-resistant covering material 26 are sandwiched between the wooden beam 2 and the wooden floor slab 3 to form a discharge hole 27. In step S3, as shown in Figure 6, the connecting member 10 is inserted from above through the through hole 24 of the wooden floor slab 3, and the lower side (tip side) of the connecting member 10 is placed inside the recess 20. In step S4, the filler material 30 is injected into the injection hole 23. This filling is carried out until the filler material 30 is discharged from the discharge hole 27, as shown in Figure 1.

[0022] This embodiment provides the following effects. (1) A recess 20 is formed in the wooden beam 2, and a through hole 24 is formed in the wooden floor slab 3. The upper and lower ends of the connecting member 10 are inserted into the recess 20 and the through hole 24, and then a filler 30 is filled into the gap between the recess 20 and the connecting member 10 to join the wooden members together and construct the wooden structure 1. This makes it possible to realize a wooden structure 1 in which wooden members are firmly joined together. Furthermore, since the wooden members 2 and 3 are joined together with steel connecting members 10 and filler material 30, joining the wooden members 2 and 3 together is relatively easy. In addition, this filler material 30 has higher shear strength and shear rigidity than wood, which improves the stability of the wooden structure 1.

[0023] (2) An injection hole 23 was provided from the side of the wooden beam 2 to the center of the recess 20, and the filler material 30 was injected into the gap between the recess 20 and the connecting member 10 through this injection hole 23. Thus, the filler material 30 could be filled without any gaps between the recess 20 and the connecting member 10. Furthermore, since the injection hole 23 is provided so as to reach the center of the recess 20, the distribution of the filler 30 within the recess 20 can be made uniform when the filler 30 is injected. Furthermore, the injection holes 23 are provided such that they become higher as they move from the side of the wooden beam 2 towards the center of the recess 20. Therefore, by injecting the filler material 30 into the recess 20 through the injection holes 23 from the side of the wooden beam 2, the filler material 30 can be densely packed into the recess 20.

[0024] (3) By interposing a fire-resistant covering material 26 between the wooden beam 2 and the wooden floor slab 3, it is not necessary to bring the wooden beam 2 and the wooden floor slab 3 into contact, and the wooden beam 2 and the wooden floor slab 3 can be joined relatively easily. Furthermore, by interposing a fire-resistant covering material 26 between the wooden beam 2 and the wooden floor slab 3, the spread of fire between the wooden beam 2 and the wooden floor slab 3 can be prevented in the event of a fire.

[0025] [Second Embodiment] Figure 7 is a front view of a wooden frame 1A to which the wooden structure according to the second embodiment of the present invention is applied. Figure 8 is an enlarged cross-sectional view of the portion of the wooden frame 1A enclosed by the dashed line C. The timber frame 1A comprises wooden timber columns 50, wooden lower timber beams 51 connecting the bases of the timber columns 50, wooden upper timber beams 52 connecting the tops of the timber columns 50, and wooden timber walls 53 provided within the frame plane enclosed by the timber columns 50, the lower timber beams 51, and the upper timber beams 52.

[0026] The lower surface of the wooden wall 53 is fixed to the upper surface of the lower wooden beam 51 by connecting members 10 provided at predetermined intervals. The upper surface of the wooden wall 53 is also fixed to the lower surface of the upper wooden beam 52 by connecting members 10 provided at predetermined intervals.

[0027] The following describes the joint structure of the upper surface of the wooden wall 53 (that is, the joint structure between the wooden wall 53 as the lower wooden member and the upper wooden beam 52 as the upper wooden member), but the joint structure of the lower surface of the wooden wall 53 (that is, the joint structure between the lower wooden beam 51 as the lower wooden member and the upper wooden wall 53 as the upper wooden member) has a similar configuration.

[0028] A first recess 60 is formed at the upper end of the wooden wall 53. The wooden wall 53 is provided with an injection hole 23 that extends from the side of the wooden wall 53 to the center of the first recess 60. A second recess 61 is formed at the lower end of the upper wooden beam 52, opposite to the first recess 60. The lower end of the connecting member 10 is inserted into the first recess 60, and the upper end of the connecting member 10 is inserted into the second recess 61.

[0029] A leak-proof tape 25 is interposed around the first recess 60 and the second recess 61 between the wooden wall 53 and the upper wooden beam 52. This leak-proof tape 25 forms a discharge hole. The gap between the first recess 60 and the connecting member 10 is filled with grout material 30 through the injection hole 23. According to this embodiment, the same effects as those described in (1) to (3) above are obtained.

[0030] [Third Embodiment] Figure 9 is a longitudinal cross-sectional view of the wood structure 1B according to the third embodiment of the present invention. Figure 10 is a DD cross-sectional view of the wood structure 1B in Figure 9. In this embodiment, the structure of the first recess 70, the second recess 71, and the connecting member 10B differs from that of the first embodiment. The connecting member 10B comprises a plate portion 11 interposed between the wooden beam 2 and the wooden floor slab 3, a cylindrical first locking portion 12 extending downward from the plate portion 11 and inserted into the first recess 70, and a second locking portion 13 extending upward from the plate portion 11 and inserted into the second recess 71. The second locking portion 13 is plate-shaped. The first recess 70 is larger by a predetermined dimension than the outer diameter of the first locking portion 12 of the connecting member 10B. The second recess 71 is slightly larger than the outer diameter of the second locking portion 13 of the connecting member 10B. According to this embodiment, in addition to the above-mentioned (1) to (3), the following effects are obtained.

[0031] (4) Since the connecting member 10B is composed of a plate portion 11, a first locking portion 12, and a second locking portion 13, the wooden members can be firmly joined together by the connecting member 10B.

[0032] Furthermore, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of the present invention are included within the scope of the present invention. For example, in the first and second embodiments described above, the connecting member 10 is made of steel and is cylindrical in shape, but it is not limited to this and may be cylindrical or rectangular in shape. Also, the connecting member 10 is not limited to steel and may be made of concrete block. Furthermore, in the embodiments described above, the wooden members were wooden beams 2, 51, 52, wooden floor slab 3, wooden column 50, and wooden wall 53, but the type of wooden member is not particularly limited, and for example, wooden studs may also be used. Furthermore, in each of the embodiments described above, a fire-resistant covering material 26 was installed between the wooden beam 2 and the wooden floor slab 3. However, the invention is not limited to this, and a gap may be secured between the wooden beam 2 and the wooden floor slab 3, or a filler material may be used instead of the fire-resistant covering material 26.
