Description

[Detailed description of the invention] This invention relates to a temporary scaffold structure for exterior work, etc. that is temporarily installed along the outer wall of a building under construction, and is used when the space between it and an adjacent building is narrow. This provides temporary scaffolding, which consists of a wide framework scaffolding connected to a single-pipe scaffolding.

An embodiment of the present invention will be described below based on the attached illustrative drawings. FIG. 1 shows a building frame support bracket 1 to be used;
This bracket 1 consists of a long vertical pipe 4 and a short vertical pipe 5, which are connected to each other by a horizontal member 2 and a diagonal member 3 so that their upper ends are located at the same level. It is something.

Reference numeral 6 designates a screw jack, which has a shaft portion 8 inserted into the upper end of the single pipe 7, a catch 9 that abuts the upper end of the single pipe 7, and a long vertical pipe 4 that protrudes from the catch 9 and is attached to the bracket 1. It consists of a threaded shaft portion 10 inserted into the lower end of the pipe, and a female threaded body 11 with a handle that is screwed into the threaded shaft portion 10 and supports the lower end of the long vertical pipe 4.

12.13 is a connecting pin for connecting the long vertical pipe 4 and short vertical pipe 5 of the bracket 1 to both the front and rear support pipes 15.16 of the scaffolding frame 14 shown in FIG. A stopper flange 17, 18 is provided in the center.

Normally, both the front and rear support pipes 15 of the building frame 14 are used rather than the single pipe 7.
16 is used with a slightly smaller diameter.

Therefore, the long vertical pipe 4 of the bracket 1 is constructed with the same diameter as the single pipe 7, and the short vertical pipe 5 is constructed with the same diameter as the frame support pipes 15, 16. , the spacing between the outer surfaces of the frame support pipes 15 and 16 is made equal to the spacing between the outer surfaces of the vertical pipes 4 and 5 at the front and rear of the bracket 1, and the connecting pins used for the long vertical pipes 4 are Only the lower part 12a of the pin 12 has a large diameter so that it can be inserted into the long vertical pipe 4, and in contrast to the lower part 12a of the large diameter pin, the upper part 12b of the small diameter pin is inserted into the frame support pipe 15. The outer surface of the building frame support pipe 15 connected to the long vertical pipe 4 is slightly eccentric so that it is flush with the outer surface of the long vertical pipe 4.

Of course, since the short vertical pipe 5 of the bracket 1 and the frame support pipe 16 are concentrically connected by the connecting pin 13, the connecting pin 12 should be the same as the connecting pin 13 whose upper and lower pin parts are concentric and small diameter. Even when used, the long vertical pipe 4 and the building frame support pipe 15 can be connected so that their outer surfaces are flush.

2 and 3 show a monotube scaffold 19 and a framework scaffold 28 connected to each other by the above-mentioned bracket 1, screw jack 6 and connecting pin 12.13, the monotube scaffold 19 being Vertical single pipes 7 arranged in parallel at regular intervals are connected to each other by horizontal single pipes 20 and pipe clamps 21, and are further reinforced with braces as necessary. A bracket 23 supporting the board 22 is attached via a pipe crank 24, and the outer end of a wall connector 26, one end of which is connected to a building exterior addition 25, is connected to a vertical single pipe 7 with a pipe clamp 27. Due to this, the single pipe scaffolding 19 is temporarily installed vertically along the outer wall 25 of the building.

In the frame scaffolding 28, the building frames 14 are vertically connected by connecting pins, and cloth boards (scaffolding boards) 30 are constructed between horizontal pipes 29 of horizontally adjacent building frames 14, and further horizontally. Braces 31 are interposed between the front and rear support pipes 15 and 16 of adjacent building frames 14,
This framework scaffold 28 is supported on the monotube scaffold 19 by brackets 1.

That is, the shaft part 8 of the screw jack 6 is inserted onto each single pipe 7 of the single pipe scaffold 19, and the lower end of the long vertical pipe 4 of the bracket 1 is fitted into the threaded shaft part 10 of this screw jack 6. the long vertical pipe 4 of this bracket 1.
Predetermined connecting pins 12.1 are provided on the top and on the short vertical pipe 5, respectively.
3, both the front and rear support pipes 15 and 16 of each lowermost building frame 14 of the framework scaffolding 28 are connected.

This frame scaffolding 28 is also connected to the building outer wall 25 by connecting the outer end of the wall joint 32, which has one end connected to the building outer wall 25, to the support pipe 15 of the building frame 14 with a pipe clamp 33.
5, each screw jack 6 is temporarily installed vertically along
The flange 17.18 of the connecting pin 12.13 is clamped between the front and rear vertical pipes 4, 5 of the bracket 1 and the front and rear supports 15,16 of the building frame 14 by adjusting the internal threaded body 11 up and down.

Further, between each bracket 1, a cloth board (scaffolding board) 34 is installed between the horizontal members 2.

Furthermore, in the above embodiment, the long vertical pipe 4 of the bracket 1
Another auxiliary single pipe 35 is arranged in parallel across the single pipe 7 sandwiching the pipe 7 and the support pipe 15 of the building frame 14, and these single pipes 7
, 35, the long vertical pipe 4 and the single pipe 35, and the building frame support pipe 15 and the single pipe 35 are connected and reinforced with pipe clamps 36, 37, and 38.

According to the temporary scaffolding structure of the present invention that can be implemented as described above,
When it is not possible to use the entire work scaffold as a frame scaffold due to the relationship with an adjacent building, and the lower part must be a single-tube scaffold that is narrow, it is possible to attach the upper frame scaffold to the outer wall of the building. This upper framework scaffold can be supported by the vertical single pipe of the lower single pipe scaffold without having to support it through a special shaped bracket, reducing the cost of the entire temporary scaffold and the cost required for its assembly work. It can be reduced.

Moreover, the interposed jack jacks ensure that the vertical load of the upper frame scaffold is transferred to the lower single-pipe scaffold, allowing the frame scaffold to be safely and reliably supported. By simply connecting it to the outer wall, a special type of highly safe temporary work scaffold can be obtained from the lower single pipe scaffold and the upper frame scaffold.

Incidentally, a screw jack can be used instead of the connecting pins 12 and 13, and a connecting pin can be used instead of the screw jack 6.

Furthermore, the structures of the single tube scaffold 19 and the framework scaffold 28 are not limited to those shown in the drawings.

For example, although a torii-shaped frame 14 is shown as the frame 14 of the framework scaffold 28, it may also be a rectangular frame, an H-shaped pier-shaped frame, or any other frame having a pair of front and rear supports connected to each other by horizontal members. Anything is fine.
