Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding device for slope work such as a retaining wall, and more particularly to a scaffolding device used for construction repair and management work of a wall surface such as a retaining wall.

[Prior art]

Workers' scaffolding is required for repair and management work on shoulder walls, vertical walls such as retaining walls such as dam sides, and slopes with slopes, but it is not possible to use frame scaffolds that are constructed higher from the ground. Can not. Therefore, a scaffold suspended from the upper end of the retaining wall by a wire rope or the like is used, and an operator works on the retaining wall by resting on the suspended scaffold.

[Problems to be Solved by the Invention]

The above-mentioned suspended scaffolding is not a problem when the work area for repairs is small, but when the work area is large, the suspended scaffolding must be laid over the entire work area, and laying before the start of work There are problems that the work and the removal work after the work take a long time, the cost of scaffolding material is high, and the front and rear work time is long.

[Means for Solving the Problems]

Therefore, the present invention is intended to provide a scaffolding device that can perform a work on a retaining wall continuously and efficiently with a short erection time, a low erection cost, and therefore,
Attached to work objects represented by slopes such as retaining walls,
A plurality of supports arranged in the water level square at substantially predetermined intervals, a guide rail having a rack supported by these supports, a mover attached to the guide rail and movable in mesh with the rack, Attached to the mover,
A scaffolding deck having a pull-out type extension deck at the front end in the moving direction and a support stay attached to the scaffolding deck for transmitting the load applied to the scaffolding deck to the work object are provided. It is characterized in that the scaffolding deck can be moved through the moving element by extending the extension.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 1 indicates the slope of the road shoulder, and a guide rail 3 supported by a column 2 is provided on the road shoulder. Supports 10 are attached to the slope 1 at appropriate intervals in the horizontal direction. The support 10 has pin holes 12 formed at four corners of a base 11, and anchors 13 are driven into the pin holes 12. It is fixed with respect to the slope 1. An arm 14 is fixed to the base 11. A guide rail 20 is suspended at the tip of this arm 14 via a ring 15. The guide rail 20 is formed by fixing a corrugated rack member 22 to the lower surface of an elongated member 21 having an inverted T-shaped cross section, and the ring 15 is formed in a hole formed in a vertical portion 21A of the elongated member 21.
Is locked. Then, the horizontal portion 21 of the long member 21 forming the guide rail 20.
A roller 32 attached to a side plate 31 that constitutes the mover 30 in B,
32 is mounted, the pinion wheel 33 is engaged with the rack material 22, and the pinion wheel 33 is driven to move the mover 30 to the guide rail.
Move along 20. The pinion wheel 33 is driven by a manual steering wheel or a motor 34. The scaffolding deck 40 can be mounted by a worker, and is composed of a channel material and an iron plate, and has an extension deck 41 in the form of a drawer at one end, in other words, one end along the moving direction. There is. This extension deck 41
Is a material that can slide along the channel members 42, 42 that make up the scaffolding deck 40, and the protrusion 43 at the end of the extension deck 41 hits the stopper 43 installed between the channel members 42, 42, The extension stroke is regulated. Below the scaffolding deck 40, there is provided a support stay 50 for transmitting a load to the slope 1, and a vertical member 51, a cross member 52, and a horizontal member.
53, which are included in the same vertical plane, and the horizontal member 53 can move relative to other members along the length direction thereof, that is, the end portion, in other words, the end portion on the slope 1 side. To Laura
I have 54. By changing the position of the roller 54, the scaffolding deck 40 can be adjusted to be horizontal, and the roller 54 facilitates the movement of the scaffolding deck 40 and the like. Therefore, the scaffolding deck 40 supported by the mover 30
Part of the load, etc., loaded on this is transmitted to the slope 1 via the support stay 50, and the mover 30 moves along the guide rail 20 to move the entire scaffolding device. . When the scaffolding device reaches the end of the guide rail 20 due to this movement, a new guide rail 20 is extended and laid out.In this case, the extension deck 41 is pulled out, and the worker rests on it. Lay the extension. In the above description, the work on the slope of the side wall of the road has been described, but it can be used for work on other similar objects.

【The invention's effect】

As is clear from the above description, the scaffolding device for slope work such as the retaining wall of the present invention has the following effects. (A). A scaffolding device supported on a part of the slope of the work target is provided, and a mover is engaged with the rack of the guide rail to move, so that wide area work can be performed safely. (B). A part of the load applied to the scaffolding deck can be transmitted to the slope by the support stay and can be borne. (C). By extending the guide rail by using the extension deck, the scaffolding deck can be moved through the mover, so the material for the scaffolding can be reduced, and laying and removal can be easily performed.
