  1-3 represents the principal part of the temporary scaffold 1 using the auxiliary horizontal member 10 for temporary scaffolds of this invention. In the temporary scaffold 1, two parallel support columns 5, 5 are arranged in series at a predetermined interval, and the temporary scaffolding auxiliary horizontal member 10 is attached between the two support columns 5, 5. And the temporary scaffold board | plate 20 is constructed between the two horizontal members 10,10. In the temporary scaffold 1, the temporary scaffold plate 20 is formed in a rectangular shape, and two hook portions 21 and 21 are provided so as to protrude from each short side. In the figure, reference numeral 6 denotes a wedge receiver for the column 5. Moreover, although illustration is abbreviate | omitted in this temporary scaffold 1, a handrail material, a bracing, etc. are suitably installed between the support | pillars 5 and 5 arrange | positioned in series.

  As shown in FIGS. 1 to 4, the auxiliary scaffold auxiliary horizontal member 10 is provided with a rod body portion 11 to which the two hook portions 21 and 21 of the temporary scaffold plate 20 are attached. On both sides of the rod body portion 11, there are provided wedge portions 12, 12 wedged to the wedge receivers 6, 6 of the two columns 5, 5. Two stopper portions 15 are provided on the rod body portion 21 of the auxiliary horizontal member 10.

  As shown in FIGS. 4 to 7, the stopper portion 15 regulates the sliding of the hook portions 21, 21 on the rod body portion 11, and sets a clearance S formed on the long side of the temporary scaffolding plate 20 at a predetermined interval. It is a member for prescribing below. At least two stopper portions 15 are provided on the rod body portion 11 of the auxiliary horizontal member 10. In this embodiment, the stopper portion 15 is a protruding piece portion formed on the rod body portion 11. The stopper portion 15 that is a protruding piece portion can be provided to the rod body portion 11 by an extremely simple technique such as welding.

  The position of the stopper portion 15 is the position of the hook portion 21 that is engaged with the rod body portion 11, that is, the position where the hook portion 21 is attached to the temporary scaffold plate 20, or the temporary scaffold plate 20 is installed on the auxiliary horizontal member 10. It is set in consideration of the position and the like. In general, the attachment position of the hook portion 21 to the temporary scaffolding plate 20, the installation position of the temporary scaffolding plate 20, and the like are set according to predetermined standards, and therefore the stopper portion 15 is formed corresponding to various standards.

  Further, the position of the stopper portion 15 does not hinder the hook portion 21 from being attached to the rod body portion 11 and corresponds to the position of the hook portion 21 within a range in which the hook portion 21 is not excessively slid. Is set appropriately. For example, when the temporary scaffolding plate 20 is installed at a normal position (for example, the center between the columns 5 and 5), the stopper portion 15 and the hook portion 21 come into contact with each other. It is the position. Thus, if the stopper part 15 and the hook part 21 are too close, the engaging position of the hook part 21 will be restricted to the very narrow range, and there exists a possibility that the smooth assembly operation of the temporary scaffold 1 cannot be performed. The position where the hook portion 21 is not excessively slid is a position where a gap S (see FIG. 2) described later does not become wider than a predetermined interval when the stopper portion 15 restricts the sliding of the hook portion 21. The specific interval between the stopper portion 15 and the hook portion 21 at the normal position is set in accordance with various standards as described above, and is approximately 25 to 40 mm.
