SOLUTION: A column 11 is formed with a lateral through bolt hole 14 extended through a side blind mortice 12, and a beam 16 is formed with a longitudinal blind bolt hole 18 extended through a tenon 17 at an end part and a lateral through bolt hole 19 extended across the back part of the bolt hole 18. The tenon 17 of the beam 16 is fitted into the blind mortice 12 of the column 11. A clamping bolt 21 with a bolt hole 22 is inserted into the bolt hole 14 of the column 11 and the bolt hole 18 of the beam 16, and a latching bolt 26 is inserted through the bolt hole 22 of the clamping bolt 21 into the bolt hole 19 of the beam 16. After that, the beam 16 is joined to the column 11 through the fixation of the latching bolt 26 to the beam 16 and clamping by the nut 23 of the clamping bolt 21.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a wooden construction, such as a joint at the end of a beam to the side of a column or a joint at the end of another beam to the side of one beam. T for joining the end of the second joining member to the side of the first joining member
The present invention relates to a character joint (connection) structure.

[0002]

2. Description of the Related Art In order to increase the joining strength of first and second joining members, a T-shaped joining (joint) fitting having a bolt fixing portion for each joining member is used to indirectly join both joining members. Joining has been done.

[0003] However, in the indirect joining structure using such joining fittings, since the amount of gap between the bolt and the first and second joining members and the bolt holes in the joining fittings is not constant, load is applied to both joining members. However, there is a problem that the two joining members are individually displaced, and a gap is generated therebetween.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a T-shaped joint structure which has no risk of displacement between the first and second joining members and has a simple structure. That is the task.

[0005]

According to the present invention, there is provided a T-shaped joint structure for a wooden building, wherein blind mortises (mortise recesses) are respectively formed in a side portion of the first joint member and an end portion of the second joint member.
A mortise and a tenon are provided, and both parts are tenon-fitted, while the first joint member and the second joint member each have a lateral through-bolt hole leading to a blind mortise and a lateral joint hole of the first joint member. A vertical blind bolt hole extending longitudinally through the tenon and a transverse through bolt hole extending across the back of the vertical blind bolt hole;
The first joint member has a lateral through bolt hole and the second joint member has a vertical blind bolt hole, and the distal end portion has a bolt hole, and the base end portion is in contact with the anti-blind mortise side of the first joint member. A fastening bolt engaged with the fastening nut is inserted, and a latch bolt that penetrates through the bolt hole at the tip of the fastening bolt is inserted into the lateral through bolt hole of the second joint member. The first joining member and the second joining member are fastened through the fixing of the first joining member and the second joining member via the fastening of the fastening bolt by the fastening nut.

In general, a bolt hole for inserting a fastening bolt, which is composed of a horizontal through bolt hole of the first joint member and a vertical blind bolt hole of the second joint member, has a length at the center in the lateral direction of the first joint member. A pair of bolt holes for the second joint member is provided at the center in the horizontal direction, and a pair of bolt holes for inserting the tightening bolts is provided. Each fastening bolt can be inserted into a bolt hole for inserting a fastening bolt, and a retaining bolt can be inserted through a bolt hole of a pair of fastening bolts.

[0007] Further, a nut receiving recess may be provided on the tightening nut contact side of the first joint member so that the tightening nut and the tightening bolt do not protrude from the side of the first joint member. it can.

In the joining structure of the present invention, relative displacement of the first and second joining members is prevented by the tenon engagement between the blind mortise and the tenon.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a joint structure according to an embodiment of the present invention.

The drawings illustrate a form in which the end of the beam is joined to the side of the pillar. The pillar 11 is provided with a blind portion at the center in the lateral (width) direction of the opposing one side and the other side. It has a mortise hole 12 and a pair of upper and lower nut receiving recesses 13, and has a pair of upper and lower lateral through bolt holes 14 extending from each nut receiving recess 13 to the blind mortise 12.

On the other hand, the beam 16 has a tenon, a pair of upper and lower vertical blind bolt holes 18 extending in the longitudinal direction through the tenon, and a pair of vertical blind bolt holes 18 in the lateral center of one end.
1 horizontal through bolt hole 1 extending up and down across the back
9.

The column 11 and the beam 16 fit the tenon 17 of the beam 16 into the blind mortise hole 12 of the column 11, while the nut 11 receiving recess 13 of the column 11 forms a pair of upper and lower horizontal through bolt holes 14 and the beam 16. Each of a pair of tightening bolts (wing plate bolts) 21 having an elliptical bolt hole 22 at the tip is inserted into each of a pair of upper and lower tightening bolt insertion bolt holes formed by a pair of upper and lower vertical blind bolt holes 18. And beam 16
, A locking bolt 26 is inserted through the bolt hole 22 at the tip of the two fastening bolts 21, and the beam 1 is passed through the nut 27 of the locking bolt 26.
6 and firmly by tightening each tightening bolt 21 via the tightening nut 23.

[0013] The joining structure of the present invention can be implemented in various other forms, and is not limited to the above-described form.

[0014]

According to the joining structure of the present invention, since the joining portions of both joining members are tenon-fitted, there is substantially no danger of relative displacement between them.

Further, according to this joint structure, since only bolts and nuts are used without using a T-shaped joint or the like as in the prior art, member costs, work costs and the like are low.
