Abstract

PROBLEM TO BE SOLVED: To provide a column-base metal fitting, by which an error on the execution of works of an anchor bolt is absorbed and which can be fixed firmly onto foundation concrete. SOLUTION: A pair of leg section pieces 8, 8 are installed oppositely at the lower end of a metal fitting body 1, on which the lower section of a column P is fixed, and a slot 11 long in the radial direction of a circular clamping backing plate 10 is formed at the proper place of the clamping backing plate 10 rotatably bridged to the leg section pieces 8. The housing opening 14 of a clamping nut 13 screwed at the front end of an anchor bolt 12 penetrated into the slot 11 is formed between the clamping backing plate 10 and the metal fitting body 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column base fitting for a wooden building used for directly fixing a column to a foundation concrete.

[0002]

2. Description of the Related Art In a wooden building, a column is fixed directly to a foundation concrete (in a sense that a base is not interposed) by using anchor bolts installed in the foundation concrete. It is common to mount a pillar on top and assemble it.However, conventionally, if there is a slight error in the installation at the anchor bolt installation position, there is no means to absorb the error, and the anchor bolt installation work There are various adverse effects such as redo. The present invention has been made by focusing on such disadvantages of the conventional example.

[0003]

Means for Solving the Problems A pair of leg pieces are provided at the lower end of a metal body for fixing a lower portion of a pillar, and a circular tightening support plate rotatably mounted on the leg pieces is provided at an appropriate position. A storage gap for a fastening nut screwed into a tip of an anchor bolt which is provided with a long hole in the radial direction of the tightening receiving plate or a plurality of through holes at different positions in the radial direction, and which penetrates the long hole or the through hole. Is provided between the fastening receiving plate and the metal body.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a column base metal according to the present invention. FIG. 1 is a longitudinal sectional view showing a use state, and FIG.
FIG. 3 is an X-ray cross-sectional view, and FIG. 3 is an exploded perspective view.

In the figure, reference numeral 1 denotes a metal body, and the metal body 1 is formed by welding a pair of L-shaped members 1A, 1A and a rectangular member 1B to each other to form a square main body piece 2 having the same cross section as the column P. And a joint piece 3 erected at the center of the main body piece 2. The joint piece 3 is provided with a through hole 5 for penetrating the drift pin 4, and the through hole provided in the through hole 5 and the column P is provided. A positioning notch 7 for matching the position with the hole 6 is provided at the upper end of the joint piece 3.

At the lower end of the metal body 1, that is, at both sides of the main body piece 2, leg pieces 8, 8 are continuously connected to each other, and are partially formed in a horizontally long window 9 provided at a lower side of the leg piece 8. A circular tightening receiving plate 10 is engaged with the leg pieces 8, 8 and is rotatably assembled.

The tightening receiving plate 10 has a long hole 11 which passes through the center of rotation (rotation) and is long in the radial direction. The tightening nut 1 is screwed to a tip end of an anchor bolt 12 passing through the long hole 11.
3 is provided between the tightening receiving plate 10 and the metal body 1.

The leg piece 8 is formed by welding the member to the rectangular member 1B. At the same time as the welding operation, the fastening receiving plate 10 is partially engaged with the horizontally long window 9 as described above. Together, they are erected and assembled on the leg pieces 8.

Then, the tightening receiving plate 10 is rotated in the horizontal direction so that the position of the anchor bolt 12 into which the nut 13A protruding from the foundation concrete Bc is screwed coincides with the position of the elongated hole 11, and the positioning is performed. The column base metal A is placed on the foundation concrete Bc so that the anchor bolt 12 penetrates the long hole 11, and a tightening nut 13 is screwed and fastened to the tip of the bolt 12 projecting into the storage gap 14. The foot metal A is fixed to the foundation concrete Bc.

[0010] A slit 15 is provided at the lower end, and a column P with a positioning drift pin 4A traversing the slit 15 is lowered in place so that the joining piece 3 is engaged with the slit 15. Drift pin 4
A engages with the positioning notch 7 provided at the upper end of the joint piece 3 so that the through hole 5 on the joint piece 3 side and the through hole 6 on the column P side are aligned with each other, and the drift pin 4 is The column P is fixedly erected on the foundation concrete Bc via the column base metal A by engaging with the base.

The slot 11 provided in the tightening receiving plate 10 is
Anchor bolt 1 from the mounting position of column P (column base metal A)
In order to absorb a slight shift when the installation position of 2 is shifted, the receiving plate 10 is lengthened in the radial direction as described above, and by rotating the receiving plate 10, any one of the longitudinal directions thereof can be absorbed. Although the anchor bolt 12 can be penetrated through the portion, the same function as that of the elongated hole 11 can be expected even if a plurality of through holes are arranged at different positions in the radial direction.

In the embodiment, since the joint piece 3 is engaged with the slit 15 to fix the metal body 1 and the column P to each other, the member on the metal A side is overlapped on the outer surface of the column P. Therefore, corrosion of the pillars due to moisture can be prevented in advance without causing accumulation of moisture due to polymerization.

[0013]

The present invention has the configuration described above,
It is possible to provide a column base hardware which can absorb errors in the construction of anchor bolts and can be firmly fixed on foundation concrete.
