Japanese Patent No. 2902633 (2nd page, FIG. 1)
[0004]
[Problems to be solved by the invention]
The conventional example has an advantage that the column can be firmly fixed as compared with a traditional fixing device that joins the column and the base so-called mortise. However, since the column is directly fixed to the foundation concrete, the column is mounted on the base. It cannot be applied to a standing structure and has application restrictions.
[0005]
The present invention was devised to provide an apparatus that can fix a column to foundation concrete via a foundation as well as using traditional tenon joints.
[0006]
[Means for Solving the Problems]
A joining bracket constructed by setting up a joining rod on the substrate is placed and fixed on the foundation concrete in the substrate, and the joining rod inserted into a vertical hole provided in a foundation on the foundation concrete, A structure of the connecting rod fixed by inserting and fixing the upper side to a pillar standing on the base, engaging the lower side protruding from the lower end surface of the column, and inserting the fixing rod through the base into these It is what.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of a column fixing device used for a wooden building according to the present invention, FIG. 1 is a partially cutaway front view of the main part, FIG. 2 is a transverse sectional view of FIG. 1, and FIG. FIG. 4 is a perspective view of the joint fitting.
[0008]
In the figure, reference numeral 1 denotes a joining metal fitting. The joining metal fitting 1 is configured by standing a joining rod 4 on a substrate 3 provided with notches 2 and 2 at opposite ends, and a pair of anchor bolts 6 projecting from the foundation concrete 5. The base plate 3 is placed on the foundation concrete 5 so that the notch 2 is engaged with the tip portion of the bolt, and a fixing nut 8 is screwed and tightened to the tip of the bolt 6 via a seat plate 7 on the foundation concrete. Mounted and fixed.
[0009]
The notch 2 is elongated in the width direction of the foundation concrete 5 and the through holes 9 of the anchor bolts 6 provided in the seat plate 7 are elongated in the longitudinal direction of the foundation concrete 5. This is to absorb errors in the construction accuracy of the anchor bolts 6 installed in the.
[0010]
Further, the joining rod 4 is erected in a round bar shape having slits (corresponding to the gap 10) as a whole on the substrate 3 so that the gap members 4a and 4a having a semicircular cross section are opened. The upper and lower pair of fixing rods 19A and 19A are provided with through holes 12 and 12 for insertion. However, the joining rod 4 may be constructed by standing a square-shaped brazing material on the substrate 3 as in the embodiment, and the gap 10 forms a slit in the center along the longitudinal direction of a single brazing material. May be configured.
[0011]
The base 13 placed on the foundation concrete 5 is provided with a recessed hole 14 for engaging the fixing nut 8 screwed to the anchor bolt 6 and a vertical hole 15 for fitting the joint rod 4, The fixing nut 8 is fitted in the recessed portion 14 of the base 13 and the joining rod 4 is fitted in the vertical hole 15, and is placed on the foundation concrete 5 via the substrate 3 of the joining metal 1.
[0012]
An anchor bolt different from the anchor bolt 6 and a nut screwed to the bolt are used for fixing the base 3 to the foundation concrete 5.
[0013]
Posts 16 provided upright on the base 13, which was equipped with a connection rod 18 which is fastened with latching rod 19 fitted to upper side to the lower end opening of the vertical hole 17, projecting from the lower end surface of the columnar 16 , lower the engaging said joining rod 4 fitted to the base 13, a fixed rod 19A and inserted through through the through-hole 20A formed in the base 13 to the junction lever 4 and the connecting rod 18 base of the connecting rod 18 erected a pillar 16 on the 13, it is then secured.
[0014]
The connecting rod 18 is formed by bending a steel plate, and is inserted into a partition plate shape at the center along the longitudinal direction of the round tubular main body 18a having an inner diameter substantially coincident with the outer diameter of the joining rod 4. Provided with a piece 18b, the through hole 22A that matches the through hole 20A for inserting the fixing rod 19A provided in the base 13, and the through hole 20 for inserting the locking rod 19 provided in the column 16 The through hole 22 is provided, and one end on the through hole 22 side is inserted into the vertical hole 17 provided in the column 16, and the locking rod 19 is inserted into the through hole 20 and the through hole 22 to be fixed to the column 16. Then, the other through-hole 22A side protruding from the column 16 is fitted into the joint rod 4 so that the sandwiching piece 18b is sandwiched between the gaps 10 of the joint rod 4, and is inserted into the vertical hole 17, so that A fixing rod 19A is inserted into the matching through hole 20A and through hole 22A and fixed to the base 13. It is.
[0015]
The connecting rod 18 of the embodiment is configured with a tube having a circular cross section, so that there is no problem even with a tube having a square cross section, but due to the relationship with the vertical hole 17 (circular in cross section) provided on the column 16 side. In addition, the circular cross section is more suitable for mass production.
[0016]
In addition, in the embodiment, the sandwiching piece 18b is provided so as to function as a shear resistance surface with respect to the pulling force and to generate a high proof stress, to eliminate rattling and to determine the directionality during assembly. Therefore, this can be omitted. The fitting between the engagement tube and the connection tube should be as close as possible to the clearance (radial direction) between the two as much as possible and should be in a so-called close-fitting state. It is done.
[0017]
【The invention's effect】
Since the present invention is configured as described above, the pillar is directly fixed to the foundation concrete as well as the foundation, so that it is possible to obtain an earthquake-resistant frame structure capable of dealing with shaking such as an earthquake.
