【００１６】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection device between a hole-down hardware (pull-down hardware) and an anchor bolt used for fastening columns to a foundation concrete in a wooden building. It is. 2. Description of the Related Art An anchor bolt erected on a foundation concrete is connected to a hole-down metal fastened to a column through a base placed on the foundation concrete so that the column is fastened to the foundation concrete. The connection device between the hole down hardware and the anchor bolt in the wooden building
It is publicly known without giving specific examples. In the known connecting device, specifically, an upper end of an anchor bolt is arranged to a hole-down hardware position through a base, and a nut is screwed to the upper end. Like that. Therefore, even if the conventional example adopts a configuration in which the columns are fastened to the base concrete via the base, the base itself is free from the base concrete. Not only is it necessary to tighten the base to the foundation concrete by screwing a nut to the upper end of the standing anchor bolt, but also the base must be fastened to the foundation concrete at a position away from the pillar, When the column is lifted by the load, the base fastened to the column is also easily lifted by the metal joint, and therefore the fastening strength of the column to the foundation concrete is not always satisfactory. [0005] The present invention has been devised for the purpose of providing a connection device in which the pillar and the base are firmly fastened to the foundation concrete and the construction work is also suitable. [0006] Anchor bolts erected on the foundation concrete are connected to hole-down hardware fixed to the columns through a base placed on the foundation concrete, and the columns are attached to the foundation concrete. In a connection device for a hole-down metal fitting and an anchor bolt in a wooden building, which is tightened, a screw of a flanged nut having a flange portion embedded in the upper surface of the base and locked at the upper end of the anchor bolt inserted into the base. The lower part of the cylindrical part is connected by screwing, and the lower part of the intermediate screw rod whose upper end is locked to a hole-down metal fitting is screwed to the upper part of the screw cylindrical part. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a connection device for a hole-down metal fitting and an anchor bolt in a wooden building according to the present invention. FIG. 1 is a partially cutaway front view, and FIG. It is. In the drawing, 1 is a foundation concrete, 2 is a base placed and fixed on the foundation concrete 1, and 3 is a base 2
A joint metal fitting 4 is fixed to a corner formed by the pillar 3 and the base 2 on the pillar erected on the top, and a bracing 5 is joined to the base 2 and the pillar 3 via the joint metal 4. is there. In the vicinity of the pillar 3 of the base 2, a through hole 6 is provided. In the through hole 6, a screw portion 7 on the upper end side of an anchor bolt 7 erected by embedding a lower part of the foundation concrete 1 is provided.
a, and a flanged nut 8 is screwed and fastened to the screw portion 7a, and the base 2 is placed on the foundation concrete 1 and fixed as described above. [0010] A flanged nut 8 (for example, Japanese Utility Model No. 8-107)
No. 01, Japanese Patent Application Laid-Open No. 9-269003, and the like are known in that they are composed of a flange portion and a screw tube portion), and include a flange portion 8a and a screw tube portion 8b, and are provided on the screw tube portion 8b ( While screwing the lower portion of the screw hole) into the screw portion 7a of the anchor bolt 7, the upper surface of the base 2 is cut by the cutting blade 8c provided on the lower surface of the flange 8a, and the flange 8a is embedded in the upper surface of the base 2. And is locked (in the axial direction of the anchor bolt 7). In addition, at places other than the vicinity of the pillar 3,
The base 2 is fastened to the foundation concrete 1 by anchor bolts 7 'and flanged nuts 8' screwed to the anchor bolts 7 '. A lower part of the intermediate screw 9 is screwed into the upper part of the screw cylinder portion 8b, and an upper part of the intermediate screw 9 is a hole-down metal member 11 fixed to the column 3 with a screw 10 (a specific example will be described). The device of this embodiment is formed by penetrating through a tightening receiving piece 11a (which will be known soon), and screwing and tightening a nut 12. An anchor bolt 7, a flanged nut 8,
It goes without saying that the intermediate screw 9 or the hole-down metal 11 does not need to be limited to the illustrated one (embodiment). Since the present invention has the above-described configuration,
At a position close to the column, the column and the base can be fastened to the foundation concrete, and therefore, even if a pull-out force acts on the column, it can be dispersed to the foundation side, and the column and the foundation are firmly fastened to the foundation concrete. Get the status. [0015]
