DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column base metal fitting for construction, and more particularly to a column base metal fitting for building a column base on a concrete foundation.

[0002]

2. Description of the Related Art Conventionally, when a column base 51 is erected in the construction of a frame 50 of a wooden building as shown in FIG. This connection processing is shown in FIGS.
As shown in FIG. 5, a square tenon 51a is formed at the end of the column base 51 to join the base 54 and the column base 51, which are fastened by anchor bolts 53, 53 embedded in the concrete foundation 52. A mortise 54a is provided at a predetermined position of the base 54. The mortise 54a is a rectangular recess for receiving the tenon 51a of the column base 51. The tenon 51 a of the column base 51 is fitted into a tenon hole 54 a provided on the base 54, and the base 54 and the column base 5 are fitted with hole-down hardware (building column base hardware) 55.
Tighten with 1.

[0003] Here, the hole-down metal fitting 55 is an L-shaped fitting, and is a column base so that the column base 51 can be tightened by a column base anchor bolt 56 previously embedded in the concrete foundation 52. 51 is fixed to a predetermined position by a plurality of bolts 57. Since the hole-down hardware 55 fixed to the column base 51 with the bolt 57 is separated from the base 54 by the amount of the interference, the hole-down hardware 55 is inserted into the anchor bolt hole of the hole-down hardware 55. By tightening the nut 58, the column base 51 is attached to the base 54.
Can be tied to.

[0004] Further, the column base metal fittings for construction may be V-shaped metal fittings 61 as shown in FIG. The V-shaped metal member 61 is provided in a mortise (square) provided on a base 64 which is fastened to a concrete foundation 62 by an anchor bolt 63.
After the tenon (square) is fitted, the column base 65 can be tightly attached to the base 64 by abutting the base 64 and the column base 65 and fixing them with a plurality of nails 66.

[0005]

However, in order to erect a column base using such column base metal fittings 55 and 61 for construction, the column base must be placed on a base. Therefore, (1) It is difficult to form a square tenon and tenon. (2) The length of the base, beams and girders must be changed. (3) Damage to the base due to the load on the column base. (4) It is not possible to replace the entire base after the column base is erected. There were difficulties such as.

In order to solve such difficulties, there has been proposed a side plate 71 as a column base metal fitting for a building as shown in FIG.
The attachment plate 71 is fastened to the concrete foundation 73 by the anchor bolt 72, and the notch 74 a cut out to the column base 74 is fitted and fixed by a plurality of bolts 75, so that the column base 74 is fixed to the concrete foundation 73. Can be tied.

However, in order to machine the cutout portion 74a of the column base 74, the machining is time-consuming because the cutout is directly cut by a saw due to the manufacturing cost. In addition, in such a configuration, since it is difficult to perform positioning, there is a problem in workability. SUMMARY OF THE INVENTION The present invention has been made to solve such conventional difficulties, and an object of the present invention is to provide a column base metal fitting for a building which improves workability of processing and constructing a column base and a base.

[0008]

SUMMARY OF THE INVENTION A column base metal fitting for a building according to the present invention that achieves the above object is a column base metal fitting for building a column base on a concrete foundation. The main body of the main body is formed of a steel material having a U-shaped cross section in which the upper surface abuts the column base and the lower surface abuts the concrete foundation, and is embedded in the concrete foundation in the gap surrounded by the U-shape of the main body. A nut that fixes the lower surface to the anchor bolt that extends through the part, a pin that fixes the upper surface to the tenon pipe that is fixed to the pedestal and extends through the upper surface, and a hole that penetrates the lower surface and into the gap And an adjuster which is screwed to the extended anchor bolt and turned in one direction, and is pressed into contact with a tenon pipe extending through the upper surface and into the gap.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a column base metal fitting for a building according to the present invention. A column base metal fitting for a building according to an embodiment of the present invention is one in which a column base is erected directly on a concrete foundation (cloth foundation), and as shown in FIGS. Is tied to the anchor bolt 3 embedded in the base. The main body 5 of such a column base metal fitting 1 for a building is formed of a steel material having a rectangular cross section so that the upper surface 5a contacts the column base 4 and the lower surface 5b contacts the concrete foundation 2. A nut 6 for fixing the lower surface 5b to an anchor bolt 3 extending through a hole 5e formed in the lower surface 5b, Fixed upper surface part 5
a pin 8 for fixing the upper surface portion 5a to the tenon pipe 7 extending through a hole 5d formed in the lower surface portion 5a, and an anchor bolt 3 extending through the hole 5e of the lower surface portion 5b and extending into the gap portion 5c. And a controller 9 to be combined. The tenon pipe 7 is buried by a predetermined length in a round hole formed in the column base 4, and a pin 10 penetrating the column base 4 and the tenon pipe 7 embedded in the column base 4 is press-fitted.

The adjuster 9 comprises a nut 9a which can be screwed to the anchor bolt 3 embedded in the concrete foundation 2, and a column base 4
And a square flat washer 9b to be pressed against a tenon pipe portion 7a protruding therefrom. The adjuster 9 is rotated in one direction so that the hole 5 in the upper surface 5a of the main body 5 is formed.
mortise pipe portion 7a extending through hole d into cavity 5c
Can be pressed against.

In order to erect the column base 4 with the thus constructed column base metal fitting 1, first, the anchor bolt 3 previously embedded in the concrete foundation 2 is inserted into the hole 5 e of the lower surface 5 b of the main body 5. And the main body 5 is placed on the concrete foundation 2. A rectangular flat washer 11 is attached to the anchor bolt 3 extending through the hole 5e of the lower surface 5b of the main body 5.
Then, the nut 6 is tightened to fix the lower surface 5b.
The adjuster 9 is screwed on the anchor bolt 3 to which the nut 6 is screwed.

Next, in order to erect the column base 4 to which the tenon pipe 7 is fixed on the main body 5 fixed to the concrete foundation 2, the tenon pipe 7 is inserted into a hole 5d in the upper surface 5a of the main body 5.
The pin 8 is pressed into a hole 7b formed in the tenon pipe portion 7a to fix the upper surface portion 5a. Then, the square flat washer 9b of the adjuster 9 screwed to the anchor bolt 3 is turned in a direction in which the square flat washer 9b can be brought into contact with the tenon pipe portion 7a, and the square flat washer 9b of the adjuster 9 and the tenon pipe portion are rotated. 7a. Thereby, together with the main body 5 formed of a steel material having a rectangular cross section, the load of the column base 4 can be received by the anchor bolt 3, the adjuster 9, and the tenon pipe portion 7a.

Since the column base metal fitting 1 for a building is directly fixed to the concrete foundation 2 instead of the base 12, FIG.
In the frame 20 of the wooden building shown in FIG.
It is no longer necessary to process the joint for 2,
Beams and girders can be unified in length. Also, since the column base 23 is not directly mounted on the bases 21 and 22,
At any time, the base panels 21 and 22 can be replaced with wall panels and the like. Furthermore, since the holes 5d and 5e of the main body 5, the tenon pipe 7 and the like are all circular, positioning becomes easy.

[0014]

As described above, according to the architectural column base hardware of the present invention, it is not necessary to make a difficult connection such as a square on the base, and the length of the base, beam and girder can be reduced. Processing of column bases and bases
Construction workability is improved. With this, processing of wooden building
Construction costs can be reduced.

Further, since the column base is not directly mounted on the base, damage to the base due to the load on the column base can be prevented.
