DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framework scaffold, and more particularly to a handrail frame for a framework scaffold.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing an assembled state of a conventional scaffold. As shown in FIG. 4, a conventional framework scaffold includes, for example, a pair of parallel buildings 12, 12 and
The building frame 10 consisting of the horizontal land 11 connecting the building 12 is positioned at a predetermined interval by crossing a cross braid 40 between two pins or the like protruding from the building 12 at predetermined vertical intervals. The strength is guaranteed. Furthermore, the cloth board 20 is horizontally stretched over each horizontal land 11 of the pair of building frames 10 and 10 arranged at the above-mentioned predetermined intervals, and assembled in multiple stages.

[0003] The safety of the worker who works on the cloth board 20 of the framework scaffold is ensured by the cross braces 40. In recent years, in order to further ensure the safety of the worker, one aspect (the work target) is required. Side different from the side)
Instead, it is covered with a handrail frame.

[0004] That is, as shown in FIG.
Numeral 0 denotes a plate 80 having a through hole 81 fixed to a vertical member 71 of a rectangular outer frame, for example.
A fixing pin 0 is used to support and fix to the building frame.

[0005]

However, the handrail frame for a scaffold scaffold described above is bulky and heavy in comparison with a cross braid made of steel, so that a large space is required for transportation and storage. It takes time to build and disassemble. In particular, as the number of workers is decreasing and the population is aging, and the number of skilled workers is decreasing, attention has been paid to the safety of the handrail frames for the framework scaffolding, and labor saving in construction and dismantling of the framework scaffolding has been promoted. It has been demanded.

The present invention has been proposed in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a handrail frame for a scaffolding scaffold which can save space occupied during transportation and storage and can achieve weight reduction. It is assumed that.

[0007]

In order to achieve the above object, the present invention employs the following means. That is, FIG.
As shown in FIG. 3 to FIG.
And a cloth plate 20 horizontally hung on the horizontal ground 11 of the building frame 10.
In the handrail frame for scaffolding scaffolding that covers one side surface of the scaffolding scaffolding, which is assembled in multiple stages, the upper half handrail portion 2 forming a gate shape
And a V-shaped fall prevention unit 3 continuously provided at the lower end of the handrail unit 2. The height dimension from the upper member 21 of the handrail unit 2 to the V-shaped vertex 31 of the fall prevention unit 3 is determined. The construction frame is formed so as to match the distance between the upper and lower cloth boards 20 of the frame scaffold, and to protrude the handrail section 2 above the cloth board 20 so that the drop prevention member 3 hangs down below the cloth board 20. 10 is a handrail frame for a scaffold supported and fixed to 10.

Further, fixing holes 5a and 5b for mutually fixing a pair of framed scaffolding handrail frames 1a and 1b supported and fixed to the upper and lower building frames 10 are provided with upper members 21 of the handrail member 2.
A configuration provided at each of the center portion and the V-shaped apex 31 of the fall prevention portion 3 may be added.

Further, the drop prevention member 3 is provided with a handrail portion 2.
It is also desirable that the left and right vertical members 22 be swingably connected to the lower ends of the vertical members 22.

[0010]

According to the above construction, the lower half of the handrail frame for the scaffolding scaffold is formed by the V-shaped fall prevention portion 3, so that the whole is lighter than a rectangular shape. Also, if the stacking is performed so that the V-shaped fall prevention portions 3 are abutted against each other, the occupied volume during transportation and storage is reduced.

In particular, in a configuration in which the fall prevention section 3 is pivotally attached to the left and right lower end portions of the handrail section 2, the fall prevention section 3 is provided.
In the folded state, the vertical dimension is reduced to about 1/2.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a front view of an embodiment according to the present invention, and FIG. 2 is a configuration diagram showing an assembled state thereof.

First, the embodiment can be applied to the conventional framed scaffold shown in FIG. 4, and as shown in FIG. 1, a gate-shaped handrail portion 2 is formed in an upper half and a V-shaped is formed in a lower half. The drop prevention part 3 is connected with the reinforcing material 9 and the dimension from the upper end of the handrail part 2 to the V-shaped apex 31 of the drop prevention part 3 is set to the distance between the upper and lower cloth boards 20 in the framework scaffold. I agree.

A fixing pin 6 and a fixing plate 7 are provided below the left and right vertical members 22 of the handrail 2 for supporting and fixing the frame 10 of the framework scaffold. FIG.
As shown in FIG.
To the building 1 of the building frame 10 corresponding to the height position of the cloth board 20.
The handrail portion 2 is made to protrude above the cloth plate 20 by being fitted into the receiving metal fitting 13 fixed to the fixing plate 2 and inserting the insertion hole 7a formed in the fixing plate 7 into the pin 14 of the building 12. The fall prevention member 3 is fixed in a state of being suspended below the cloth plate 20. In addition, the said pin 14 protrudes from the building 12 for fixing the conventional cross bracing 40,
It can be commonly used for fixing the handrail frame for the framework scaffold.

Further, in this embodiment, the fall prevention unit 3
Fixing holes 5a and 5b are respectively formed in the V-shaped vertex 31 and the center of the upper member 21 of the handrail member 2, and the framed scaffolding handrail frame 1a supported and fixed to the upper building frame 10 and the lower building The framed scaffolding handrail frame 1b supported and fixed to the frame 10 is mutually fixed by bolts 5b.

According to the embodiment having the above construction, the lower half of the handrail frame 1 for the scaffolding scaffold is formed as the V-shaped fall prevention member 3, so that the V-shaped fall prevention portion 3 is stacked so as to abut. This reduces the occupied volume during transport and storage, and can reduce the weight and save the occupied space during storage or transport without losing safety when mounted on the framework scaffold.

Further, the V-shaped vertex 31 of the fall prevention portion 3
And a fixing hole 5 is provided in the center of the upper member 21 of the handrail member 2 to connect the upper and lower framed scaffolding handrail frames 1a and 1b, so that required strength can be secured. In addition, the number of connection points per one handrail frame for a framework scaffold can be reduced, so that the time required for mounting can be saved.

FIG. 3 is a front view of another embodiment according to the present invention. In this embodiment, the left and right oblique members 32 and 33 of the drop prevention unit 3 are particularly connected to the left and right vertical members 22 of the handrail unit 2. It is pivotally attached to the lower end.

Accordingly, when the handrail frame for scaffolding scaffolding is not used for transportation or storage, the oblique members 32 and 33 are folded from the left and right and fixed by the holder 24 provided at the center of the lower member 23 of the handrail unit 2. Almost 1 /
2, the space occupied during the transportation and storage can be further reduced.

[0020]

As described above, according to the present invention, the weight and the occupied space can be reduced without impairing the safety. Therefore, the safety of the worker at the time of constructing and disassembling the framework scaffold is improved. And the space occupied during storage and transport can be saved.

In particular, the occupied space can be further reduced by pivotally attaching the fall prevention member to the handrail so as to be swingable.
