Description

The present invention relates to a side wall panel for closing a lateral space of a scaffold board suspended in a suspended scaffold.

Conventionally, when constructing or renovating an existing structure such as a highway or a bridge at a high place, a suspended scaffold extending along the existing structure has been constructed.

The hanging scaffolding board for constructing the hanging scaffolding (hereinafter, simply referred to as “scaffolding board 1”) is generally configured as shown in FIGS. 1 to 3.

The scaffolding plate 1 may be referred to as a first girder side frame 3A and a second girder side frame 3B made of square pipe members arranged in parallel at a distance (when both are not distinguished, they are simply referred to as "girder side frame 3". ) To support the floor material 2, and at both ends of the pair of girder side frames 3A and 3B, a first wife side frame 4A and a second wife side frame 4B (both) made of a circular pipe material, respectively. When no distinction is made, it may simply be referred to as "wife side frame 4"). Further, both ends of the center frame 5 made of a circular pipe material arranged on the lower side of the floor material 2 are connected to the gable side frame 4.

By the way, as typified by an expressway, the extension direction of an existing structure is not necessarily limited to a straight line direction, but includes a curved direction that draws a curve. Therefore, it is necessary to construct the suspended scaffolding in the corresponding direction.

Therefore, the gable side edges of the adjacent scaffolding plates 1 are connected to each other by a joint device so that the distance between them can be adjusted. The gable side frame 4 is configured so that both end portions do not protrude from the outer surfaces of the first girder side frame 3A and the second girder side frame 3B, and the first end portion 6a of both end portions is the first girder side frame 3A. The socket 7 is formed by opening the outer surface of the second end portion 6b, and the plug 8 is formed by projecting the insertion member projecting from the second end portion 6b to the outside of the outer surface of the second gable side frame 3B. A joint device is configured in which a plug 8 is slidably inserted into a socket 7 between adjacent scaffolding plates 1, 1 and gable-side frames 4, 4.

At this time, the socket 7 and the plug 8 fitted to each other are held in place by inserting the connecting pin 9 in a penetrating state, but the insertion hole of the plug 8 into which the connecting pin 9 is inserted is a long hole 10. The plug 8 and the socket 7 are configured to allow sliding within the range of the elongated hole 10, whereby the distance between the adjacent scaffolding plates 1 and 1 can be adjusted.

When constructing a suspended scaffold, the scaffold plate 1 is arranged along the existing structure by alternately connecting the socket 7 and the plug 8, and is suspended under the existing structure by a cord 11 such as a chain. Will be done. In order to enable such a chain or the like to be suspended by the cord 11, window holes 12 facing the center frame 5 are provided in the floor material 2 at predetermined intervals, and the frame 5 is provided with window holes 12 at predetermined intervals. , A hanging metal fitting 13 facing each window hole 12 is provided. Therefore, by connecting the cord 11 to the hanging metal fitting 13, the frame 5 is suspended via the metal fitting 13.
