Description

  The present invention relates to a panel body receiving jig for temporarily holding a panel body in a state of being lifted by a predetermined height from a work surface when the panel body such as a wall panel is erected and safely performing the work.

  In general, in a panel construction method that uses building panel materials such as floor panels and wall panels to construct a building, the building panel materials are lifted by a crane, transported to a predetermined location, and assembled. Made. In particular, when standing the wall panel on the floor, the operator must guide the crane so that the suspended wall panel is transported to an appropriate position, or assist the work with multiple persons. Do. However, the crane operator may not be able to see the worker in the shadow of the suspended wall panel, and the operator's limbs may be pinched between the wall panel and the floor. there were. Such accidents when installing wall panels were prevented by the safety awareness of each worker.

  Accordingly, the present applicant temporarily holds the wall panel in a state where the wall panel is lifted from the floor surface by interposing a jig serving as a spacer between the wall panel and the floor surface when the wall panel is erected. We thought that it was preferable to stand the wall panel upright on the floor by removing the jig after sufficiently checking safety while preventing the limbs from being pinched.

  By the way, there is no suitable jig as a spacer interposed between the wall panel and the floor surface. For example, the wall panel is removed from the floor surface by sandwiching a bar-shaped tool or a plate material having an appropriate thickness. I had to lift a little and deal with it.

  As described above, Patent Documents 1 and 2 and the like describe the following techniques as apparatuses for providing a predetermined interval between a wall panel and a floor surface.

  Patent Document 1 proposes a position adjusting device that includes a rotary moving member having an elliptical cross section on which a wall panel is placed, and a rotary operation lever fixed to the rotary moving member. The wall panel placed on the rotationally moving member is held in a state where the wall panel is lifted to a predetermined height from the floor surface. By rotating the rotationally moving member, the width and height directions of the wall panel are maintained. Position adjustment is performed.

Patent Document 2 proposes a holding device that includes a holding body that can hold a wall panel up and down with a horizontal axis as a fulcrum, and that pushes up the holding body with a jack. The wall panel lifted to a predetermined height is fixed against the ceiling surface, and a gap formed between the wall panel and the floor surface is covered with a baseboard.
