DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold base device for supporting a work scaffold assembled on a work site such as a slope, and is used for a work scaffold assembled on a roof covered with tiles or the like. And a suitable scaffold base device.

[0002]

2. Description of the Related Art For a variety of construction work involving work at high places, such as construction work for a house or repair work for a building outer wall, for example, a work scaffold is assembled and work is performed on the work scaffold. There are many. A commonly used work scaffold is assembled into a scaffold by fixing a metal round pipe, a bar-shaped wood, or the like with a fixture such as an orthogonal clamp.

[0003] A commonly used work scaffold 100 is:
As shown in FIG. 8, a vertical member 101 and a horizontal member 102 obtained by cutting a metal round pipe into appropriate lengths, and these vertical members 101
And an orthogonal clamp 103 for fixing the cross member 102, a scaffold plate 104 serving as a scaffold for an operator, and a foot module 105 supporting the vertical member 101.

The lower end of the vertical member 101 is the foot module 1
05, and is vertically supported. The horizontal member 102 is stretched over a plurality of vertical members 101 supported vertically, and is fixed to each vertical member 101 and the orthogonal clamp 103. Thus, the work scaffold 1
In the case of 00, since the vertical member 101 and the horizontal member 102 are assembled in a scalloped shape, they are installed while maintaining mechanical strength while being lightweight and easy to assemble. The scaffold plate 104 is a lightweight and mechanically strong plate-like member made of a material such as an aluminum alloy, for example. Work as a foothold for workers.

[0005] The foot module 105 includes a grounding portion 106 provided on the grounding surface, and a joint portion 1 into which the vertical member 101 is inserted.
07, and a fixing portion 108 for fixing the ground portion 106 and the joint portion 107, and are integrated with each other.
The ground contact portion 106 is a plate-like member made of a material such as an alloy, and is installed on the ground surface to stabilize the foot module 105. The joint 107 is a pipe-shaped member made of a material such as an alloy, has an inner diameter slightly larger than the diameter of the vertical member 101, and the lower end of the vertical member 101 is inserted. Fixed part 108
Is a right-angled triangular plate-shaped member made of a material such as an alloy, and two sides sandwiching the right angle of the right-angled triangle are grounded portions 106.
And the joint 107 are welded and fixed vertically.
The foot module 105 is usually provided with three or four fixing portions 108, and a ground portion 106 and a joint portion 107.
And are firmly fixed.

[0006] A wooden board 150 may be laid on the work scaffold 100 between the foot module 105 and the ground plane. The work scaffold 100 supports a heavy load by mounting the foot module 105 on the wooden board 150 without soiling or damaging the ground surface. Also, wooden board 1
50 has a foot module 105 because it has some elasticity.
Works to reduce wobble.

A work scaffold 100 that is usually used is
It is configured as described above, and is assembled at the work site, and serves as a scaffold when the worker works at a high place. When the work scaffold 100 is installed on a horizontal ground surface, the vertical members 101 are vertically supported by the foot module 105 and are stabilized. However, since the working scaffold 100 has the vertical contact portion 106 and the joint portion 107 of the foot module 105 fixed vertically by the fixing portion 108, the vertical member 101 is supported vertically when the ground contact surface is inclined. Not stable.

Therefore, the work scaffold 100 serves as a base for horizontally installing the foot module 105 when the foot module 105 is installed on the inclined contact surface.
A piece of wood 151 of an appropriate thickness is inserted between the foot module 105 or the wood board 150 and the grounding surface, and is used.
01 is supported vertically. Piece of wood 151
Is a wedge shape or a plate shape obtained by performing simple processing on a piece of wood or the like generated when processing wood at a work site. The wood piece 151 is used by adjusting the wedge angle and thickness (hereinafter, referred to as angle adjustment) in order to adjust and install the foot module 105 at a horizontal angle. The angle of the piece of wood 151 may be adjusted and a plurality of pieces may be used in combination to adjust the angle of the foot module to be horizontal.

[0009]

The work scaffold 100 requires a piece of wood 151 for each of the foot modules 105 installed on the inclined surface. It is necessary to adjust the angle of each piece of wood 151 in accordance with the angle of. However, when the work scaffold 100 is installed,
51 is hardly deformed, so that the wedge-shaped piece of wood 151 is cut little by little while measuring with a level or the like, or the pieces of wood 151 of various thicknesses are combined so that the foot module 105 is supported horizontally. Fine adjustments are made. Therefore, when the work scaffold 100 is installed, the work of adjusting the angle of the piece of wood 151 takes time and is extremely inefficient.

Further, the work scaffold 100 becomes very slippery depending on the state of the ground contact surface when the wood piece 151 is wet with water due to, for example, rainfall. Furthermore, work scaffold 1
In the case of 00, when a plurality of pieces of wood 151 are used in combination as described above, they may be broken. Therefore, there is a possibility that the work scaffold 100 may cause a serious accident such that the wood piece 151 slips or collapses, causing the foot module 105 to be loose and, in extreme cases, to collapse.

Further, the work scaffold 100 is made of a piece of wood 15
Since 1 is hardly deformed, the angle adjustment becomes more difficult when it is installed on a non-planar curved inclined surface such as a roof tile of a house. Further, the work scaffold 100 is provided with a piece of wood 151 so that the load is not concentrated and the roof tile is broken.
Must be cut along the curved surface of the roof tile so that the surface is in contact with the roof tile. However, the work scaffold 100
As described above, the work of three-dimensionally processing the wood piece 151 takes too much time, and it is difficult to install the wood piece 151 on a curved inclined surface.

Therefore, according to the present invention, since it is formed of an elastic material, it does not require an angle adjustment when used on an inclined work site, stably supports the work scaffold, and further has a curved inclined surface. It is an object of the present invention to provide a scaffold base device which is suitable for use in a base.

[0013]

In order to achieve the above-mentioned object, a scaffold base device according to the present invention comprises a base portion mounted on an inclined surface and a support portion for supporting a work scaffold. When,
An angle adjusting section is provided between the base section and the support section to hold the support section in a substantially horizontal state, and these sections are formed of an elastic material.

According to the scaffold base device of the present invention configured as described above, the angle adjusting section is elastically deformed by the load of the scaffold applied to the support section and naturally adjusted to a suitable angle. . In addition, the scaffold base device can be installed without forming a gap even when used on a curved inclined surface by elastically deforming the base portion following the state of the grounding surface, and when wet with water. However, a sufficient installation area is secured, and the platform is stably supported without slipping or collapsing.
