Description

  The present invention is, for example, a main pillar material or abdominal material constituting a tower for an overhead power transmission line, or a step bolt for raising and lowering in a tower component for attaching a step bolt to a rail for an elevator installed in the tower. The present invention relates to a mounting device.

  When a worker moves up and down on a steel tower for an overhead power transmission line, a step bolt is generally attached to a main pillar material constituting the steel tower, and the worker moves up and down using the step bolt.

  As a conventional step bolt, for example, as shown in FIG. 16, a trapezoidal metal fitting W is attached to a main pillar material P constituting a steel tower by welding or the like, and a step bolt is installed in a bolt hole formed at the front end of the trapezoidal metal fitting W. There is a configuration in which S is mounted.

  Further, as another step bolt S, for example, as shown in FIG. 17, there is one using a fastening member L that is fixed with screws by sandwiching a main pillar material P constituting a steel tower. In this step bolt S, a trapezoidal bracket W is attached to one of a pair of semicircular arcs forming a fastening member L by welding or the like, and the step bolt S is mounted in a bolt hole formed at the front end of the trapezoidal bracket W. It is.

In addition, as disclosed in Patent Document 1, for example, there is a type in which a step bolt is directly attached to a tower base by tightening a nut or the like.

  However, as shown in FIG. 16, when a trapezoidal fitting W is attached to the main pillar member P constituting the tower by welding or the like, and the step bolt S is attached to the bolt hole formed at the front end of the trapezoidal fitting W, the tower is manufactured. At that time, since the trapezoidal metal fittings W were individually attached to the main pillar material P of the steel tower in the state before the galvanization construction by factory welding, the production cost of the entire apparatus was high.

  In addition, since such a trapezoidal metal fitting W is manufactured by room temperature plastic working, troubles such as easy breakage occur when a load is applied during use.

  For example, as shown in FIG. 16, in a trapezoidal metal fitting W attached by welding or the like to a main pillar material P constituting a steel tower, a plate-like member provided with a bolt hole formed at the front end of the trapezoidal metal fitting W is broken. There was a situation where a part of the trapezoidal metal fitting W was missing.

  Further, in the vicinity of the flange joint portion of the steel tower, the stepped bolts S are arranged at intervals where the flange joint portions become obstructive and the distance between the step bolts S is widened or narrowed so that workers can easily climb. An impossible situation occurred.

  Furthermore, when the trapezoidal metal fitting W is welded after galvanization, zinc may be eluted and mixed into the welded part, leading to deterioration of quality, and this may cause aging deterioration or damage of the trapezoidal metal fitting W. In this case, it is difficult to repair the trapezoidal metal fitting W by field welding.
