Abstract

PROBLEM TO BE SOLVED: To provide legged support reinforcement for post-fitting of a support in a concrete structure which can be fixed, with the length of a screw bolt as the leg adjusted arbitrarily in conformity with the depth of a hole of the structure, and of which the screw bolt can be made to be of a small diameter. SOLUTION: In legged tubular support reinforcement P which is fixed by casting of hardening resin with the leg put in a hole bored in a concrete structure, a tubular long nut 3 is fitted in the lower end part of the support reinforcement P and fixed and a screw bolt with a short piece nut 7 is screwed therein as the leg. Even when the hole 13 bored in the structure for insertion of the screw bolt 5 as the leg is shallow due to the hindrance of a reinforcing bar, the legged support reinforcement P can meet the hole easily, since it can be fixed with the length of the leg adjusted arbitrarily. Besides, the operability is very excellent, since the hole 13 can be made such a small bored hole as simplifies execution of work, while allowing the screw bolt 5 to be held therein. Moreover, the important part of a support 1 can be reinforced rationally to prevent it from being broken, and the strength of the structure can be maintained by the reinforcing bar.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to post-installation of a pillar in a concrete structure used as a core material of a pillar when a pillar such as a handrail is erected on a structure such as a concrete parapet (hereinafter simply referred to as a structure). For reinforced pillars with feet.

2. Description of the Related Art To erect a support such as a handrail on a structure,
When concrete is poured, a recess for dropping a support is formed, and an anchor for the support is sometimes buried. On the other hand, in the case of a structure that has already been completed, a hole for erecting a pillar is drilled in the structure, but a reinforcing bar of the structure may be an obstacle to drilling.

[0003] In addition, since bending stress tends to concentrate on an upright column, particularly at the lower end thereof, to prevent breakage,
Pillar reinforcement is inserted into the pillar as a core material. Even in such a case, if the pillar or the lower end of the pillar reinforcement is inserted directly into the hole drilled in the structure, the hole becomes extremely large, requiring a lot of labor for drilling work. The hole was made small by inserting a screw bolt which is safe and fitted as a foot, and inserting the screw bolt into the hole.

Conventionally, in such a column support with feet, in order to fix a screw bolt as a foot, a split groove is formed on both sides of the column reinforcement, and the split groove is welded to the screw bolt.
Since it was immobilized and integrated, if there was a rebar failure in the drilling as described above, either the screw bolt was cut off to adjust the length, or the rebar was cut to remove the failure. Even so, it is a difficult task, especially,
Rebar cutting has the problem of impairing the strength of the structure.

[0005] In addition, since the means for welding the column reinforcement is used for mounting the screw bolt as described above, the diameter is substantially the same as the inner diameter of the column reinforcement, and in this regard, there is a restriction that the diameter of the screw bolt is reduced. .

In order to achieve the above object, the present invention provides a method for forming a hole in a concrete structure,
In the column-shaped column support with feet that is inserted into the hole and fixed by injecting the curable resin, a cylinder long nut is fitted and fixed to the lower end of the column reinforcement, and a screw bolt with a short piece nut is used as the foot. It is intended to provide footed column reinforcement for retrofitting columns in threaded concrete structures.

[0008] According to the above configuration, the diameter of the hole in which the pillar is to be erected is large enough to accommodate the screw bolt and the short nut. Alternatively, if the short piece nut is used as a flange to be hooked on the upper surface of the hole, the diameter becomes small enough to insert only the screw bolt. In any case, to adjust the foot length to the depth of the hole, with the short nut loosened, turn the screw bolt to advance and retreat to an appropriate length while tightening the short nut to the cylinder long nut Fix the screw bolt with.

[0009] The diameter of the screw bolt is not the inner diameter of the column reinforcement but a small diameter that is screwed into a cylindrical long nut fitted therein. Further, since the column reinforcement is reinforced by the cylindrical nut, it can rationally cope with bending stress concentrated on the lower end of the column.
