The following is a brief description with reference to FIGS. Core plate 2 established on bottom plate 1
Wedge guide pieces 3 having the same height as the core plate 2
4 and a main body 6 of a joining metal which is formed by erecting a mounting plate 5 on one end face in the longitudinal direction of both plates 1 and 2, by means of the mounting plate 5, tightening bolts 8 and nuts 9 on columns 7.
Installed by.

A beam 10 has its fitting space 11 fitted to the main body 6 of the joint, and driving wedges 12 and 13 having at least the same length as the wedge guide pieces 3 and 4 are fitted to the fitting space 11. The wedge guide pieces 3 and 4 are received and inserted densely along the wedge guide pieces 3 and 4 into the spare spaces 14 'and 15' of the widened longitudinal grooves 14 and 15 receiving the wedge guide pieces 3 and 4, respectively. Is pressed against the side surface of the pillar 7. A cover plate 16 is mounted on the upper surface of the beam 10, which is tightened and fixed by a plurality of bolts 18 screwed through a through hole 17 into a plurality of screw holes 2 ′ on the upper end surface of the core plate 2 of the joint fitting main body 6.

[0005]

In the above joining structure, a sufficient tightening or joining strength can be easily obtained by driving and inserting the driving wedges 12, 13 along the wedge guide pieces 3, 4. The joining strength is improved by the cover plate 16.

However, since the wedge guide pieces 3 and 4 and the driving wedges 12 and 13 have the same height (or length) as the core plate 2, the fitting space 14 provided on a horizontal member such as a beam is not provided. Naturally, the large space required for receiving the wedge guide piece and the driving wedge is required, so that it takes time and labor to excavate, and there is a disadvantage that the lacking portion of the cross member is enlarged and the strength is reduced. .

Further, in order to fix the cover plate 16 to the upper surface of the core plate 2, a screw hole 2 'must be provided in advance on the upper surface. However, the diameter of the screw hole should be at least 12 in relation to the diameter of the bolt required in this type of joint structure.
mm, and a core plate having a thickness of about 20 mm must be used for that purpose. Moreover, the core plate is usually made of iron in nature. Therefore, the weight of the core plate itself and the entirety of the joint metal body are increased, which is unsatisfactory as a joint structure of a wooden building.

[0008] Further, the main body 6 of the joint fitting attached to the column 7
When the beam 10 is mounted on the beam, the beam 10 is temporarily lifted above the main body 6 of the fitting, and the widened vertical grooves 14, 15 are aligned with the wedge guide pieces 3, 4, and the fitting empty It is necessary to fit the step 11 into the main body 6 of the joining fitting and lower it to a predetermined position, which is extremely poor in workability.

The present invention eliminates the need for providing any wedge guide piece regardless of its length in the main body of the joint, so that there is no need to provide a space in the transverse member for fitting to the wedge guide piece.
Eliminating the trouble of providing these, the connection between the main body of the joint and the horizontal member is sufficient only by driving a plate-like key from the upper and lower end surfaces thereof, thereby eliminating the disadvantages and disadvantages as described above. It has been proposed for the purpose.

[0010]
