Description

  The present invention relates to a wire rod stretching tool that stretches a wire rod such as a wire along, for example, a wall surface while changing the stretching direction.

  A plurality of wire rod stretching tools are attached to the mounting surface, and a wire rod such as a wire is hung around the wire rod stretching tool to change the stretching direction, and the wire rod is stretched.

  For example, when it is stretched on the wall of a building as a decorative material, as a building component such as a hook wire, or as a greening wire for planting, it may be stretched by crossing many wires vertically and horizontally However, one or several wires are bent 90 degrees via a wire tensioning tool, or folded 180 degrees and bent to change the tensioning direction, and are tightly tensioned even if the number is small. There is a case.

  Such a wire tensioning tool is in a protruding state, for example, by screwing a fixing portion that is a main body of the wire tensioning tool to a mounting surface such as a wall surface or via an anchor bolt protruding from the mounting surface. The fixing part is provided with a ring part or a hook part through which a wire material such as a wire is inserted.

  In general, a screw portion provided in a ring portion is screwed into a screw hole (screwed portion) provided in a fixed portion, and a ring portion is provided in the fixed portion. For example, a number of wire tensioning tools are projected on the wall surface, and the wire with one end fixed is placed parallel to the wall surface. The wire rod is stretched through the ring portion at the tip of the fixed portion of each wire rod tensioner, and bent to 90 degrees around this ring portion as a base point. It is set as the structure which stretches a wire so that it may become, and fixes the edge part.

  In other words, the conventional wire tensioning tool is simply provided with a ring portion, and is configured to be stretched while changing the tensioning direction to a desired direction by folding the ring portion through the wire or bending 90 degrees. It is the structure which can only be bent in the middle of a wire.

  For this reason, since the bent portions in the middle of the wire are not fixed, there is a risk that the entire wire may loosen when a load is applied to the stretched wire, and the last wire rod end is passed through the ring portion in sequence. The tensioning work must be completed at a stretch until it is fixed, and the work cannot be interrupted or rested on the way.

  Especially when working at high places such as extending along the wall of a building, or when tightly stretching long wires over a wide area, it is particularly easy to loosen, and this extension can be done along the way. The inability to interrupt work makes it very hard work.

  The present invention finds and solves such problems in a wire tensioning tool that stretches a wire while bending and changing the tensioning direction, and simply connects the wire to the ring portion by a simple operation with a simple configuration. Rather than being passed through, the intermediate part of the wire is clamped and fixed so that the wire can be stretched and fixed at each location. Even if it is loosened, it is clamped and fixed in each section so that the whole does not loosen, and this tensioning operation can be interrupted each time a wire rod is stretched and fixed to each wire rod tensioner, allowing a break After resuming, it will be bent again and the tensioning direction can be changed to the desired direction, etc., so that it can be tensioned and fixed to the next wire tensioning tool. It is intended to provide.
