An embodiment will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a wooden frame member and a wooden beam member of the present invention before joining the wooden column member and the wooden beam member. FIG. 2 is a front view showing a state where the wooden beam member is joined to the wooden column member. FIG. 3 is a sectional view taken along line XX of FIG. 2. In the figure, 1 is a wooden beam, 2 is a steel gusset plate, 3 is a drift pin, 4 is a bolt, 5 is a wooden pillar, 6 is a U-shaped metal part (half of a steel square short pipe), and 7 is a wooden material A gusset plate made of projecting steel for the column member, 8 is a reinforcing rib, 9 is a lag screw, 10 is a bolt, 11 is a cutout groove, 12 is a pull bolt, 13 is a bolt insertion hole of a wooden column member, and 14 is a wooden member. The bolt insertion holes 20 of the beam member are exposed portions of the steel gusset plate of the wooden beam member.

As shown in FIGS. 1 to 3, in the wooden beam member, a steel gusset plate 2 is inserted, buried and fixed from the end of the cutout groove 11 of the wooden beam 1. Notch groove 11
The groove is opened at the joint side with the wooden pillar 5 of the wooden beam 1, and is notched to a width of the steel gusset plate 2 in the vertical direction and a fixed length in the horizontal direction. The steel gusset plate 2 is a steel plate generally used for joining members to nodes of a steel structure, and the steel gusset plate 2 is provided with drift pins for fixing to the wooden beam 1. Holes and holes for fastening bolts are provided to facilitate fixing to the wooden beam 1. Here, as a fixing means of the wooden beam 1 and the steel gusset plate 2, a connector for firmly fixing the wooden beam 1 and the steel gusset plate 2 is used. A drift pin 3 having a small initial play, a high rigidity up to a yield load, and a high aesthetic property is used in the illustrated connector. Then, a drift pin 3 is driven in from one side of the wooden beam 1, the wooden beam 1 and the steel gusset plate 2 are fixed, and a moment resistance performance (both shear force and axial force resistance performance) is provided by the pin shear strength. I have. In particular, in the figure, the wooden beams 1
In order to fix the steel gusset plate 2 and the steel gusset plate 2, a part of the bolt is also tightened by the bolt 4. When the steel gusset plate 2 is buried in the wooden beam 1, one end of the gusset plate 2 is inserted leaving an exposed portion 20 exposed outside the open end of the wooden beam 2. The exposed portion 20 serves as a bolt fastening portion of the wooden pillar member to the projecting steel gusset plate 7,
The exposed portion 20 is provided with a plurality of insertion holes 14 for fastening bolts.

Next, in the wooden pillar member, a U-shaped metal member 6 is attached and fixed to the wooden pillar 5. U-shaped hardware 6
Is a shape obtained by halving a short rectangular tube made of steel, and has a U-shape in plan view. A projecting steel gusset plate 7 is formed on the middle abdomen of the U-shaped metal piece 6 and is welded in a protruding shape with the steel gusset plate facing outward. The gusset plate 7 is provided with a plurality of bolt insertion holes 13 for joining the wooden beam member to the exposed portion 20 of the steel gusset plate. In addition, the U-shaped metal member 6 is provided with a perforated hole for joining to the wooden pillar 5 on the side surface and the middle abdominal surface to facilitate attachment and fixing to the wooden pillar 5. A strong fixing means is used for attaching and fixing to the wooden pillar 5. Here, as a fixing means shown, a lag screw 9 is used for joining the side surface of the U-shaped metal member 6 to the wooden column 5, and is used for joining the middle surface of the U-shaped metal member 6 to the wooden column 5. Uses a pull bolt 12, but in addition to the lag screw 9 shown in the figure, using a fixing means such as penetrating the side surface of the wooden pillar and tightening the bolt, taking the material of the wooden pillar 5 into consideration. It is desirable to select a fixing means for firmly joining and fixing the wooden pillar 5 and the U-shaped metal member 6. In addition, the U-shaped metal member 6 is provided with reinforcing ribs 8 above and below a projecting steel gusset plate 7 welded to the middle portion thereof, and reinforces the middle plate of the U-shaped metal member 6. ing. In addition, the exposed portion 20 of the wooden beam member serves as a guide at the time of joining the wooden beam member and the wooden column member.

By the way, (1) production of a wooden beam member, that is, fixing of the wooden beam 1 to the steel gusset plate 2 and (2) production of a wooden column member, that is, a wooden column 5 in the wooden column member. By fixing the U-shaped metal member 6 in advance in a factory where manufacturing machines, tools, and the like are sufficiently provided, the production can be performed with high efficiency and high accuracy. As a result, the amount of work at the construction site can be reduced, and the workability can be improved and the construction period can be shortened. Therefore, the work at the construction site involves fastening of the wooden beam member and the wooden column member constructed at the factory. However, a plurality of bolts inserted into the exposed portion 20 of the steel gusset plate 2 of the wooden beam member are inserted. The hole 14 and the plurality of bolt insertion holes 13 drilled in the protruding gusset plate 7 of the wooden pillar member are overlapped,
Tightening the bolts with the bolts 10 is an operation of integrally fastening the wooden beam member and the wooden column member. Tightening means include rivets, bolting, and high-strength bolting. Torsier-type high-strength bolting is particularly preferable because torque can be easily controlled in the field. Then, by firmly fastening the wooden beam member and the wooden column member, the force applied to the wooden beam 1 can be transmitted to the wooden column 5 reliably.

[0010]

According to the present invention, (1) production of a wooden beam member, that is, burying / fixing work of a wooden beam and a steel gusset plate, and (2) production of a wooden column member, that is, wood of a wooden column member The work of attaching and fixing columns and U-shaped hardware can be carried out in factories that are fully equipped with manufacturing machines and tools, so that the amount of work at the construction site can be reduced. Since there is no need for precise and technical work for manufacturing the beam member and the wooden column member, the work efficiency is remarkably improved. Further, since the joining work between the column member and the beam member at the construction site can be performed by simply tightening the wooden beam member and the wooden column member manufactured at the factory with bolts or the like, the worker is skilled in the art. It is possible to improve the workability, shorten the construction period, and further reduce the cost without the need for the work.
