1 to 7 show an embodiment according to the invention of claim 1. In the figure, 1 is a frame scaffold, 2 is
The building frame that constitutes the frame scaffold, 3 is a pair of jumping brackets assembled to the building frame, 4 is two steel cloth plates hung between both jumping brackets, 5 is both jumping brackets and It is a handrail that is assembled in a frame and has a U-shaped planar shape that can be folded.

The pop-out bracket 3 is formed by joining steel pipes together to form a bracket having a right-angled inverted triangular shape with one side being a base end being a vertical pipe 33, an upper side being a horizontal pipe 34, and a lower side being an inclined pipe 35. Clamps 31 are provided at the upper end and the lower end of the vertical pipe 33, respectively, and one short sheath pipe 32 is vertically provided at the tip end of the vertical pipe 33. The clamps 31 are attached to the building frame 2 of the frame scaffold 1.

The steel cloth plate 4 has two hooks 41 at each end.
And the horizontal pipes 34 of the pair of jumping brackets 3 are hung over each other by using the hooks.

The handrail 5 is made of steel pipe and has a pair of handrails 5.
1 are arranged at appropriate intervals, and handrail pipes 52 are provided on the upper ends of both handrails.
And the girder pipes 53 are integrally laid on each other in the middle portions to form a handrail intermediate portion 5a having a length that matches the length of the steel cloth plate 4, and the pair of handrails 51 is On top,
The corner ends of the handrail both side portions 5b, each of which fits the horizontal pipes 34 of the pair of pop-out brackets 3, are folded and horizontally rotatably connected to each other. 54 are provided to rotatably fit the rotary pipes to the upper portions of the handrails 51.
The handrail pipes 55 corresponding to the length of 4 and the similar girder pipes 56 project from the lower end in parallel with the horizontal direction, and the free ends of the upper and lower handrail pipes 55 and the girder pipes 56 are vertically connected to each other. The upper and lower clamps 57, which are combined and integrated by a pipe 58, are respectively attached to the free ends of the handrail both sides 5b to be attached to the building frame 2 of the frame scaffold 1, and each of the handrails 51 is formed.
The lower ends of the clamps 57 are fitted and assembled to the respective sheath pipes 32 through the connecting pins 6, and the respective clamps 57 are fastened and assembled to the building frame 2 of the framework scaffold 1. When removed,
Both sides 5b of the handrail are folded by the rotation of the rotary tube 54.

FIG. 8 shows an embodiment according to the invention of claim 2. In this case, in the case of the previous example, the pair of pop-out brackets 3 are formed by joining steel pipes into a horizontal pipe 36 having a lower side and an inclined pipe 37 having an upper side in a right-angled triangular shape. And inclined tube 3
A clamp 31 to be attached to the building frame 2 of the frame scaffold 1 is provided at the base end of 7, and the handrail 51 of the handrail 5 is erected at the tip end,
The handrail pipe 52 is installed between the upper end of the handrail 51 and the base end of the inclined pipe 37 to form the jumping bracket 3 which also serves as both handrail side parts 5b. Further, the handrail 5 is attached to the both handrails 51.
Both ends of the handrail intermediate part 5a are folded and connected so as to be horizontally rotatable. The handrail intermediate part 5a is connected to each of the handrails 51.
The rotary tubes 54 are rotatably fitted to each other over substantially the entire length thereof, and the handrail tubes 52 are provided integrally with the upper ends of the rotary tubes 54, and the girder tubes 53 are integrally provided between the intermediate portions. Thus, a suitable number of steel cloth plates 4 are detachably hung between the horizontal pipes 36 of the pair of jumper brackets 3 which also serve as the handrail both sides 5b. Others are the same as in the previous example, and when assembled to the building frame 2 of the frame scaffolding 1, each clamp 57 is used, and when removed, the pair of pop-out brackets 3 and the handrails 5 are jointly, that is, the pair of handrail both sides. The jumping bracket 3 also serving as the portion 5b and the handrail intermediate portion 5a are folded.

According to the first aspect of the present invention, because of the above-described structure, the pair of pop-out brackets 3 are assembled to the building frame 2 by fastening each clamp 31, and the pair of pop-out brackets 3 to the building frame 2 are assembled. On the other hand, the handrail 5 is assembled by raising each handrail 51 by inserting the connecting pin 6 into each sheath pipe 32 and fastening each clamp 57 to the building frame 2, and between the pop-out brackets 3 made of steel. By straddling the cloth plate 4, it can be assembled to the frame scaffold 1 extremely easily and easily, and a landing that overhangs can be formed simply and easily on the frame scaffold 1. Of course, removal is also very simple and easy. It is possible to reduce the labor and labor, and shorten the construction period. Furthermore, since the number of members is small, the handrail 5 can be disassembled into the pair of pop-out brackets 3, the handrail 5, and the steel cloth plate 4, and the handrail 5 having a U-shaped planar shape is attached to the handrail intermediate portion 5a. Since both side parts 5b can be horizontally rotated and folded, they are not bulky during transportation and storage, and can be efficiently transported and stored, and transportation and storage costs can be reduced. Can be greatly reduced.

According to the second aspect of the present invention, because of the above-mentioned construction, the pair of jumper brackets 3 also serving as the handrail both side portions 5b are assembled to the building frame 2 by fastening the clamps 31, and both jumpers are fitted. By straddling the steel cloth plate 4 between the brackets 3, it is possible to more easily and easily assemble the frame scaffold 1 and to form a landing which is simply and smoothly projected on the frame scaffold 1. Of course, the removal can be performed similarly easily and easily, and the labor can be further reduced, and the labor can be further saved and the construction period can be shortened. Further, the number of members can be further reduced, and it can be disassembled into the pair of handrail both side portions 5b also serving as the pop-out bracket 3 and the steel cloth plate 4, and also the pair of handrail both side portions 5b having a U-shaped planar shape. Since the pop-out bracket 3 can be horizontally rotated and folded, it is not bulky during transportation, storage, etc., and can be transported and stored more efficiently, and costs such as transportation costs and storage costs can be further reduced. Overall, the construction cost can be reduced significantly.
