Description

  The present invention relates to a worktable for a single tube scaffold that can be easily mounted on a single tube scaffold.

  Traditionally, scaffolding is temporarily set up for home renovation work, but since scaffolds with work benches are expensive, many craftsmen who perform painting work temporarily build single pipe scaffolds without work benches. Work often. Here, the single tube scaffold refers to a scaffold in which two single tubes are provided so as to be parallel to the longitudinal direction at a predetermined interval.

  In such a single pipe scaffold, a gap of a predetermined width is generated between two single pipes arranged in parallel, so that the safety when the worker moves is not sufficient. Furthermore, since there is a gap between the single pipes, materials and tools related to the construction cannot be temporarily placed on the single pipe during the work, and there is a concern that work efficiency is poor. .

  Here, for example, in Patent Document 1, a load support body having a support surface that supports a load and is placed on an upper portion of the peripheral surface of two single tubes, and a lower portion of the peripheral surface of the two single tubes. There is disclosed a temporary device including a locking body to be stopped and a connecting body that is inserted into a gap between two single tubes and connects a load support and a locking pair.

FIG. 2 (c) shows a plan view of the single-tube scaffolding work table, and FIG. 2 (d) shows a side view of the single-tube scaffolding work table. Shown and explained.

  As shown in these drawings, the single-tube scaffold work table 1 includes a rectangular plane portion 2, and the side portions 3 and 4 are continuous from the left and right ends in the longitudinal direction of the plane portion 2. Is formed. The side portions 3 and 4 have a shape that exhibits a part of a cylindrical shape.

  More specifically, it seems that the inner peripheral surfaces 3a and 4a are cut out along two sides parallel to the longitudinal direction, with a part of the cylindrical shape having a diameter so as to contact the outer peripheral surface of the cylindrical single tube. It has become a shape. Therefore, since the inner peripheral surfaces 3a and 4a of the side surface portions 3 and 4 fit the outer peripheral surface of the single pipe at the time of mounting, the positional relationship between the two, and thus the positional relationship between the single tube scaffold work table 1 and the single pipe is fixed. Is maintained.

  The flat surface portion 2 and the side surface portions 3 and 4 may be integrally formed of either polyvinyl chloride or polyethylene.

  In the single pipe scaffold work table 1 according to the first embodiment, the side surfaces 3 and 4 have such a length that the inner peripheral surfaces 3a and 4a are in contact with a half of the entire outer peripheral surface of the single pipe.
