A preferred embodiment of the scaffold board gap cover of the present invention will be described below with reference to the drawings.
First, the arrangement of the scaffolding boards 13 of the temporary scaffolding 1 when the scaffolding board gap cover 2 of the embodiment of the present invention is not used will be described with reference to FIG.
In FIG. 1, a temporary scaffolding 1 is constructed by providing horizontal scaffolding pipes 12 arranged between vertical pipes 11 and incorporating scaffolding boards therein. As shown in FIG. 2 , between the horizontal scaffolding pipes 12 , a scaffolding board 13 having grips 15 provided on the end side is laid over and fixed with gripping fixtures 151 .
The scaffolding board 13 is provided with a plurality of long grooves 131 having a concave cross-section in the longitudinal direction in order to increase strength, and end metal fittings 14 are fixed to both ends of the scaffolding board 13 by welding or the like. The temporary scaffolding 1 in which the scaffolding board 13 is fixed to the horizontal scaffolding pipe 12 is arranged in a direction perpendicular to the horizontal scaffolding pipe 12 and in a horizontal direction. A gap X (see the blackened portion X in FIG. 1) is generated between the directions.

The present invention is a scaffolding board gap cover 2 used to close the gap X, and is a scaffolding board gap cover 2 as shown in FIG. 2(b) when viewed from the back side, and FIG. 3 when viewed from the front side.
The details of the scaffold board gap cover 2 will be described below with reference to FIGS. 4 to 8. FIG.
As shown in the side views of the scaffolding board gap cover 2 of FIGS. consists of
6 is a plan view of the scaffold board gap cover 2, FIG. 7 is a front view, and FIG. 8 is a bottom view. As shown in FIGS. It has a shape covering a part of the horizontal scaffold pipe 12 from the upper oblique part 231 of 23 , and a vertical part 232 is provided at the lower part of the intermediate connecting part 23 . In addition, the width of the scaffold board gap cover 2 is made to substantially match the width of the scaffold board 13 so as to make the gap as small as possible.

As shown in FIGS. 4 and 6, a plurality (four places) of U-shaped hooks 24a and 24b are provided at the tip 212 of the upper flat portion 21 and the tip 221 of the lower flat portion 22, respectively. The U-shaped gaps 241 of the plurality of hooks 24a of the plate gap cover 2 are engaged with the tips 144 of the horizontal parts 142 provided on the upper part of the end fittings 14. Since there is a gap between the tip portion 221 of the scaffolding board 13 and the elongated portion 131 of the scaffolding board 13, the hook portion 24a provided on the tip portion 212 of the upper flat portion 21 is hooked in this gap. Here, in FIG. 4, the scaffolding board gap cover 2 is not completely engaged with the end fitting 14, and a gap Y exists as indicated by symbol Y in FIG.
Similarly, the tip 145 of the lower horizontal part 143 of the end fitting 14 engages the tip 221 of the lower flat part 22 of the scaffold board gap cover 2 with the gap 241 of the U-shaped hook 24b. However, in FIG. 4, they are not completely engaged and there is a gap Y as indicated by the symbol Y.

As shown in FIG. 5, a pair of left and right nut portions 233 are fixed to the vertical plate 232 of the intermediate connecting portion 23, and the tip of the bolt 234 is inserted into the vertical surface 141 of the end fitting 14 by inserting the bolt 234. By pressing, the entire scaffold board gap cover 2 is pulled outward, thereby eliminating the gap Y in FIG. The distal end portions 212 and 221 are inserted, and they are firmly engaged and locked so as not to move.
Note that the tip portion 212 of the upper flat portion 21 is slightly inclined downward so as to be smoothly connected to the scaffolding board 13 .

A procedure for incorporating the scaffold board gap cover 2 into the end fitting 14 will be described with reference to FIG.
The upper half of FIG. 9 is a plan view of the assembly. The hooks 24a are provided at four positions corresponding to the long grooves 131, and are inserted into the end fittings 14 of the scaffold board 13 from the outside. This state is shown in FIG. 9(1), and assembly is performed in the order of (2) to (4) below.
In FIG. 9(2), both ends 212 and 221 of the scaffold board gap cover 2 are slightly expanded (in the direction of the arrow in the figure), fitted into the end metal fittings 14, and further pushed in to close the gap between the upper and lower hooks 24a and 24b. Upper and lower tip portions 144 and 145 of the end fitting 14 are engaged with the portion 241 . Specifically, this is the state of FIG. 4 described above.
Next, the bolts 234 are inserted in (3), and the bolts 234 are inserted in (4) until they become stiff, the scaffolding board gap cover 2 is pulled outward, and the scaffolding board gap cover 2 is firmly engaged with the end fittings 14. lock them so that they do not move together. This is the state shown in FIG. 5 in detail.

In this way, the gap between the scaffolding boards 13 of the temporary scaffolding 1 is closed with the scaffolding board gap cover 2, and the entirety of the temporary scaffolding 1 incorporating the scaffolding boards 13 is shown in FIG. In FIG. 10, scaffolding boards 13 are arranged in two rows and incorporated into horizontal scaffolding pipes 12. Scaffolding board gap cover 2 hides horizontal scaffolding pipes 12, and all temporary scaffoldings 1 are at approximately the same height as scaffolding boards 13. flattened across. As shown in the far right of FIG. 10, the scaffolding board gap cover 2 of the embodiment of the present invention can be installed without adjacent scaffolding boards.

Since the embodiment of the present invention is configured as described above, according to the scaffolding board gap cover 2 of the embodiment of the present invention, the gap between the scaffolding boards 13 constituting scaffolding at a construction site or the like can be almost covered. The horizontal scaffolding pipe 12 of the temporary scaffolding 1 is completely hidden, and the scaffolding board gap cover 2 and the scaffolding board 13 are almost the same in height and the scaffolding board can ensure safety in work. Since the seam of 13 does not bulge in an arch like the conventional one, the worker does not trip over it. Since there is no work, it leads to a reduction in the number of workers, good work efficiency, and there is no worry of falling due to work mistakes during installation or removal. Furthermore, loss of the scaffold board gap cover during dismantling can be prevented.
In addition, when the scaffolding board gap cover 2 is attached to and detached from the scaffolding board 13, the assembly can be easily locked by simply tightening the bolts, making it difficult to come off. Covers gaps between scaffolding boards.
It goes without saying that the present invention is not limited to the above-described embodiments as long as they do not impair the characteristics of the present invention.
