Description

  The present invention relates to a suspension rail mounting structure in which a suspension rail is attached in a substantially orthogonal direction between a pair of horizontal members constituting a scaffold, and more specifically, a safety belt for working at a high place or a suspension material for conveying a member is attached. The present invention relates to a mounting structure of a suspended rail to a construction scaffold.

  Conventionally, a safety band (lifeline) for work at high places has been attached to a construction scaffold assembled for work at a construction site or the like. This safety belt is mostly attached by attaching it to an appropriate part of the scaffold with a hook, and it is necessary to attach and detach the hook every time the operator moves the work position. In addition, depending on the mounting position, it may come off during work or may become unstable.

  On the other hand, suspending materials for conveying members are rarely attached to a construction scaffold, and building members and the like have been loaded and moved by being hung by a crane or directly carried by a worker on site.

  Under such circumstances, there have been many proposals for attaching a safety belt for working at a high place or a suspension material for conveying a member to a construction scaffold assembled for work at a construction site or the like.

  Patent Documents 1 to 3 describe the technical content of laying a master rope directly or separately between support columns provided at a construction site. By attaching a lifeline to this master rope, it is possible to attach the lifeline movably along the parent rope, but the parent rope itself is an unstable rope, and there is a looseness in the extension of the parent rope. If the weight of the master rope is too heavy, it becomes unstable support, and there is a possibility that a large shaking occurs during the work, and there is a problem that the safe work cannot be performed.

  Patent Document 4 describes a technical content in which two vertical master ropes are suspended from a building, a horizontal parent single pipe is installed between both vertical master ropes, and a lifeline is hooked on the horizontal parent single pipe. Even with the technique described in Patent Document 4, the lifeline can be attached to the horizontal parent pipe so as to be movable. However, since the horizontal parent pipe is attached to an unstable vertical parent pipe, a large shaking occurs during work. There is a problem that even the technique described in Patent Document 4 cannot perform safe work.

  On the other hand, in Patent Documents 5 and 6, by attaching a horizontal strut or a guide member made of a long steel material to a vertical strut of a scaffold or a separately provided strut, the lifeline can be freely moved along the horizontal strut or the guide member. The technical contents that it can be attached are described. In the techniques described in Patent Documents 5 and 6, a lifeline is not attached via a rope such as a master rope, and the lifeline can be attached in a more stable state than the techniques described in Patent Documents 1 to 4. However, since the horizontal support is attached to the vertical support etc. whose upper end is not fixed, the vertical support may be shaken. In this sense, the techniques described in Patent Documents 5 and 6 are stable. It was not a technology that could attach a lifeline in the state.

  In Patent Document 7, a guide rail is installed on a horizontal handrail frame and a corner handrail frame for a construction scaffold, and a sliding bracket for a hanging hook is slidably engaged with the guide rail so that a safety belt, etc. Describes the technical contents that can be mounted movably. By adopting this technology, it is possible to attach the safety belt etc. in a somewhat stable state, but the guide rail is attached to the tip of the horizontal handrail frame and the corner handrail frame, so the tip of the scaffold The weight will be applied only to the part, and in that sense, the scaffold may be easily shaken. In addition, since the sliding bracket for hanging is provided at the tip of the scaffold, it is necessary to put the safety belt hook and so on when the safety belt is attached, which is dangerous. was there.

  In addition, in these prior art documents, there is no specific description about attaching a suspension material for transporting a member, but it is assumed that a suspension material for transporting a member is attached instead of a safety belt (lifeline). However, it is a matter of course that the same problem as that when a safety belt (lifeline) is attached is generated.
