DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing fitting for fixing a pipe column to a horizontal member such as a beam.

[0002]

2. Description of the Related Art In general, hole-down hardware is used to fix a pipe column to a horizontal member such as a beam in a wooden building.

For example, as shown in FIG. 6, a bolt 16 integrally welded to a square washer 15 is inserted into an insertion hole 11 a penetrating the beam 11, and a hole-down metal fitting A is fitted to the column 16 in accordance with the bolt 16. After fixing to 12, the pipe column 12 provided with the hole-down metal A is erected on the beam 11, and the bolt 16 is fastened to the hole-down metal A.

[0004]

However, when the tube column 12 is fixed using the above-mentioned hole-down hardware A, the yield strength is 24.5 kN (2.5 tons) per piece.
Although it is possible to secure a certain level of strength, it is necessary to screw three to five coach bolts per one to fix the hole-down metal fitting A to the pipe column 12 at the site, which is low in workability. There is a problem. In addition, it may interfere with the fitting of the brass fitting, the heat insulating material, the arm bar, or the like, and the use may be restricted.

[0005] Although not shown in detail, a case where the tenon 12 is fixed to the beam 11 using a tenon pipe is also recognized, but the mortise pipe has a low yield strength of about 5.9 kN (0.6 ton). The strength cannot be secured by itself, and it is necessary to use together with the hole-down metal A described above.

In any case, the strength stipulated by the revised Building Standard Law cannot be satisfied with the lessons learned from the Great Hanshin-Awaji Earthquake in order to secure higher strength housing.

[0007] The present invention has been made in view of such problems, and in a wooden house, there is provided a fitting for fixing a pipe column to a horizontal member such as a beam with higher strength. To provide.

SUMMARY OF THE INVENTION The present invention is directed to a fixture for fixing a tube post to a horizontal member, the fixture comprising a bolt having a square washer and a bolt integrally welded, and a bolt comprising a bolt. A mounting member formed by integrally welding a nut and a mounting plate formed with a plurality of pin insertion holes, which can be screwed with the bolt, and a bolt insertion hole formed through the horizontal member through the bolt insertion hole. While the bolt is inserted, the nut of the mounting bracket is screwed into the bolt of the bolt bracket, the bolt bracket and the mounting bracket are integrally fastened to the horizontal member, and the slit formed at the end of the tube post is formed in the mounting plate. The plug is inserted, and a drift pin is driven into a pin insertion hole formed at an end of the tube post and a pin insertion hole of the mounting plate to fix the tube post.

According to the present invention, a bolt of a bolt is inserted into a bolt insertion hole formed in a horizontal member such as a beam, and a nut of a mounting bracket is screwed into a bolt protruding from the horizontal member. In addition, the bolt and the mounting bracket can be integrally fastened to the horizontal member. Then, after inserting the slit formed at the end of the tube post into the mounting plate of the mounting bracket and bringing the end surface of the tube post into contact with the horizontal member, at the end of the tube post, the surface is orthogonal to the slit and from one side. Align the pin insertion hole formed by penetrating to the other opposite surface with the pin insertion hole of the mounting plate, and drive the drift pin into the pin insertion hole of the tube column and the pin insertion hole of the mounting plate to fix the tube column Can be fixed to metal fittings.

[0010] As a result, since the pipe post is fixed by the drift pin, the work can be performed in a shorter time as compared with the bolt and nut fastening work, so that the workability can be improved and the bracing can be improved. Without interfering with
There is no restriction on the mounting position. In addition, a large proof stress can be ensured by the plurality of drift pins inserted through the mounting plate, and it is not necessary to use a hole-down hardware or the like.
