JPH04250260A - Slip-prevention tool for scaffold in roofing operation of tile - Google Patents

Abstract

PURPOSE:To prevent operators from falling off, by preventing operators on a scaffold in roofing works of tiles from slipping off from the scaffolds. CONSTITUTION:A scaffold supporting frame 3 is provided at the rear part of the main body, in which the front end is bent downward and the stopper 2 of tile edges is formed, to make a slip-preventing tool of scaffolds in the roofing operation of tiles. It is preferable to form a protrusion 5 at the upper edge of the scaffold supporting frame 3 to prevent from slipping out of scaffolds plates. In this way, falling accidents of operators causing slip on the scaffolds can be prevented and further, this has a simple structure and hence, this can be supplied in a low cost and the handling thereof is easy.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding prevention device for protecting workers from falling accidents caused by slipping of scaffolding during tiled roof listing work.

0002

[Prior Art] Conventionally, there was no suitable device to prevent scaffolding from slipping during tiled roof listing work.
When performing tiled roof listing work, a stepladder should be erected directly on the tile roof and used as a scaffold, or a scaffold board should be strung between multiple stepladders erected directly on the tile roof, or a stepladder should be placed directly on the tile roof. Scaffolding boards were attached between multiple scaffolding logs that were erected directly on the ground.

0003

[Problem to be Solved by the Invention] However, when the scaffolding is installed directly on the tiled roof as described above, the scaffolding slides on the tiled roof, and as a result, the worker who is on the scaffolding is forced to jump onto the tiled roof. Accidents of people falling to the ground or falling to the ground often occur.

The present invention was made in an attempt to protect workers from such falling accidents by preventing scaffolds from slipping.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a roof tile which has a scaffold support frame provided at the rear of the main body whose front end is bent downward to form a tile end locking part. The present invention provides a device to prevent scaffolding from slipping during roof listing work.

[0006] It is preferable that the upper end of the scaffold support frame is provided with a protrusion to prevent the scaffold plate from slipping.

[0007]

[Operation] A plurality of scaffolding anti-slip devices according to the present invention are installed on a tiled roof, and the scaffold is supported by these anti-slip devices. When installing each anti-slip device on a tiled roof,
Slightly lift the tile directly above the tile to which the anti-slip device is fixed, insert the front end of the anti-slip device between these tiles, and lock the tile end locking part to the upper end of the former tile (see Figure 2). ), the scaffold is supported within the scaffold support frame at the rear of the main body. When setting up a stepladder or a scaffold log as a scaffold, place each leg of the stepladder or the lower end of each scaffold log directly into the scaffold support frame of each anti-slip device (see Figures 4 and 5), and place the stepladder as it is on the scaffold. Alternatively, a scaffold board may be placed between each stepladder or between each scaffold log, and the scaffold board may be used as a scaffold. In this case, since the tile end locking portion of each anti-slip device at the front end of the main body is locked to the upper end of the tile, there is no risk that the anti-slip device will slide on the tile or come off the tile. Furthermore, since the lower end of each leg of the stepladder or each scaffolding log is placed directly within the scaffold support frame of each anti-slip device, there is no fear that the stepladder or scaffold log will come off the anti-slip device.

When the anti-slip protrusion of the scaffold board is formed at the upper end of the scaffold support frame of the anti-slip device, a plurality of anti-slip devices are installed on the tiled roof as described above, and the anti-slip protrusion is formed on the upper end of the scaffold support frame of the anti-slip device. Scaffolding boards will be placed horizontally on the ground (see Figure 2). In this case, since the anti-slip protrusion of the scaffold board is formed at the upper end of the scaffold support frame, the scaffold board suspended horizontally on the scaffold support frame will not slip. This scaffolding board may be used as it is as a walkway, but it is also possible to erect a stepladder on the scaffolding board and use the stepladder as it is as a scaffold, or to erect multiple stepladders on the scaffolding board and place the scaffolding board between these stepladders. The scaffold board may be used as a scaffold (see FIG. 3).

[0009]

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is the main body of the anti-slip device. The main body 1 is, for example, an elongated thick plate-like body, and the front end thereof is bent downward to form the tile end locking part 2. A scaffold support frame 3 is provided at the rear of the main body 1. As an example, the scaffolding support frame 3 has a shape obtained by obliquely cutting off the upper end of a substantially cylindrical body,
It is welded to the rear of main body 1. It is desirable to form an anti-slip protrusion 5 for the scaffold board 4 at the upper end of the scaffold support frame 3.

Reference numeral 6 is a rafter, 7 is a roofing board attached to the rafter 6, 8 is a tile attached to the roofing board 7, 9 is a tile attached to the tile 8, and 9' is a tile end locking part 2. This is the upper end of the tile 9 that locks the tile. 10 is a stepladder, 11 is a height-adjustable auxiliary leg attached to the stepladder 10, and 12 is a scaffolding log. Note that the upper part of the scaffolding log 12 is temporarily fixed to a gable board or the like on the upper floor.

[0011]

[Effects of the Invention] As explained above, according to the present invention,
Since scaffolding is reliably prevented from slipping during tiled roof listing work, falling accidents of workers due to scaffolding slipping are prevented, and the safety of tiled roof listing work is improved. In addition, since the anti-slip device of the present invention has a simple structure as described above, it can not only be provided at a low cost, but also be easily attached to and removed from the roof, and can be used for scaffolding boards, stepladders, scaffolding logs, etc. It is easy to install and remove.
