JP3631700B2 - Column and horizontal joining device - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to an apparatus for joining columns and horizontal members in a wooden building.
[0002]
[Prior art]
Needless to say, a so-called tenon joint is used in which a tenon is provided on the column side and a tenon hole is provided on the side of the horizontal member (beam, girder, etc.), and these are fitted to each other.
[0003]
[Problems to be solved by the invention]
Since the conventional example has a structure in which a tenon and a tenon hole are simply fitted, when an external force is applied to the joint due to an earthquake or the like, the column and the horizontal member rotate relatively around the tenon, This is a major factor in the vibration of the entire wooden building.
[0004]
Therefore, in order to prevent the above-mentioned rotation as much as possible, it is common to add a separate device such as using a streak or using a battledore bolt.
[0005]
The present invention has a proof strength that does not cause relative rotation of the column and the horizontal member unlike conventional tenon joints, and does not easily deform even when an external force such as an earthquake is applied. It was invented for the purpose of providing a joining device for horizontal members.
[0006]
[Means for Solving the Problems]
The above-mentioned bolt rod of the bolt metal fixture with a bolt rod protruding from the metal substrate is passed through the bonding substrate of the bonding hardware through a horizontal member, and a nut is screwed and tightened to the tip of the bolt rod protruding from the bonding substrate. The joint metal is fixed to the lower surface of the horizontal member, and the joint plate of the joint metal formed by projecting the joint plate on the joint substrate is engaged with the nut. It is configured to be inserted into a slit provided on the upper surface of the column through a long hole provided in the combined spacer and fixed to the column with a pair of fixing rods inserted from the outside of the column.
[0007]
【Example】
The drawings show an embodiment of the column and horizontal member joining apparatus according to the present invention, FIG. 1 is a sectional view, FIG. 2 is a central longitudinal sectional view of FIG. 1, FIG. 3 is an exploded perspective view, and FIG. 5 is a perspective view of a spacer, FIG. 6 is a perspective view of a bolt metal object, FIG. 7 is a sectional view of a second embodiment, FIG. 8 is a central longitudinal sectional view of FIG. 7, and FIG. It is a perspective view of the volt | bolt metal fitting applied to.
[0008]
In the figure, reference numerals 1A and 1B denote bolt hardwares, and the bolt hardwares 1A and 1B are configured by projecting (standing) a pair of bolts 3 and 3 on a flat metal substrate 2 with an appropriate interval. . A pair of through-holes provided in the horizontal member 4 at the position of the upper recessed portion 5 by fitting the hardware substrate 2 of the bolt hardware 1A, 1B to a rectangular upper recessed portion 5 provided on the upper surface of the horizontal member 4. 6 and 6 are inserted through the bolt rods 3 and 3 and combined with the horizontal member 4, and the front ends of the bolt rods 3 protruding from the horizontal member 4 are inserted through the through holes 9 provided in the bonding substrate 8 of the bonding hardware 7. It protrudes from the lower surface of the bonding substrate 8, and a nut 11 is screwed to this through a washer 10 to fix the bonding metal 7 to the horizontal member 4 in the bonding substrate 8.
[0009]
The joint metal 7 has a joining plate 12 protruding (standing) at the center of the rectangular flat plate-like joining substrate 8, the through holes 9 and 9 are provided on both sides of the joining plate 12, and the upper recessed portion The joint substrate 8 is fitted into a square-shaped lower recessed portion 13 provided on the lower surface of the horizontal member 4 so as to be directly below 5, and the above-described bolts 3 of the bolt hardware 1A and 1B and the nut 11 screwed thereto are used as described above. It is fastened to the street horizontal member 4.
[0010]
In addition, the metal substrate 2 of the bolt hardware 1A and 1B is closely fitted to the upper recessed portion 5 and the bonded substrate 8 of the bonded hardware 7 is tightly fitted to the lower recessed portion 13 and assembled to the horizontal member 4. This is because when the external force is applied in the horizontal direction, the relative rotation between the horizontal member 4 and the column 14 is further restricted by the contact between the substrates 2 and 8 and the recessed portions 5 and 13.
[0011]
The reason why the substrates 2 and 8 are housed in the recessed portions 5 and 13 is that the respective surfaces of the substrates 2 and 8 and the horizontal member 4 are the same surface. This is because the assembling work such as the flooring to be attached is performed smoothly.
[0012]
The column 14 is provided with a slit 15 at the center of the upper surface, and passes through the slits 15 so as to cross the slits 15 so as to coincide with the pair of through holes 16 and 16 provided in the bonding plate 12 of the bonding metal 7. 17 is provided.
[0013]
The horizontal member 4 is placed on the pillar 14 via a spacer 18 that engages and accommodates the nut 11 and the tip of the bolt rod 3 in the through hole 21, and the pillar is passed through a long hole 19 provided in the spacer 18. The drift plate 20 is inserted into the through-hole 17 and the through-hole 16 that are aligned with each other, and the joining plate 12 and the column 14 that are fitted into the slit 15 are joined to each other.
[0014]
Therefore, the joint metal 7 is assembled to the horizontal member 4 using the bolt metal 1A, 1B in the factory, and the spacer 18 is attached to the joint plate 12 protruding from the horizontal member 4 using the long hole 19 at the site. The joining plate 12 protruding from the spacer 18 is inserted into the slit 15, and the drift pin 20 is driven into the through hole 17 and the through hole 16, thereby obtaining the joined state of the horizontal member 4 and the column 14.
[0015]
The bolt hardware 1A, 1B and the joint metal 7 are made of metal rather than raw material, but the spacer 18 is made of synthetic resin in the embodiment.
[0016]
By storing the nut 11 in the through hole 21 provided in the spacer 18 as described above, there is no need to provide a special recess for the nut 11 in the column 14 or the horizontal member 4. It is not complicated, and it is possible to prevent a reduction in the proof stress of the column 14 and the horizontal member 4 by providing the recessed portion.
[0017]
The first embodiment shows an example in which another horizontal member is joined in a direction orthogonal to the horizontal member 4, and the mortise 22 is provided in the horizontal member 4, and the other horizontal member 4 ' The mortise 23 is provided in the terminal of the mortar 23 and the mortise 23 is dropped into the mortise hole 22 so that the horizontal members 4 and 4 ′ are joined to each other, and the joined state is maintained by the floor material superimposed on the upper side. .
[0018]
The metal substrate 2 of the bolt metal object 1A used in the first embodiment has a shape in which a portion corresponding to the mortise 22 provided in the horizontal member 4 is cut out.
[0019]
It goes without saying that it is not always inconvenient to use a bolt rod instead of the drift pin 20.
[0020]
【The invention's effect】
Since the present invention is configured as described above, a joining device in which the column and the horizontal member are joined and does not require a special reinforcing device and does not cause relative rotation of both members. Can be provided.
