DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing method which is carried out when a steep roof of about 50.degree.

[0002]

2. Description of the Related Art Heretofore, a roof with a steep slope has been worked on by temporarily installing a scaffold on the entire surface of the roof or by changing the scaffold. Workers use a rock climbing tie rope, Rolip, to ensure safety.

[0003]

The roofing work according to the conventional method requires a lot of labor and cost for temporary installation of a scaffold,
Still, the safety of workers is not enough. In addition, the worker must walk on the already-roofed roofing material, and the roofing material has a drawback that scratches and dents are liable to occur, which is a problem to be solved.

[0004]

As a means for solving the above-mentioned problems in the prior art, a roof roofing method for a steep roof according to the present invention is, as shown in the embodiment in the drawings, a roof purlin 1. A door roller 2 running in the direction of the purlin is provided, and has a length that covers substantially the entire length of the roof in the gradient direction, and has a stair scaffold 3 for ascending and descending in the gradient direction of the roof. The moving scaffold 5 configured in the space 4
In the direction of the main building of the roof, the work area width of the roofing work is sequentially moved in order, and the roof material stacked in the receiving space 4 is lowered.
A roofing operation is performed on the stair scaffold 3.

[0005]

The moving scaffold 5 travels using the roof purlin 1 as a rail. By the movement of the movable scaffold 5, the transport of the roof material or the like stacked on the receiving space 4 is also performed.
The stair scaffold 3 provides a scaffold for the worker over substantially the entire length of the roof in the gradient direction, so that there is less danger such as a fall accident and the fear of the worker can be reduced. The worker can move freely and safely in the direction of the slope of the roof with the stair scaffold 3, and can perform the roofing work from the stair scaffold 3.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
As shown in FIG. 1, when a steep roof of about 50 ° is constructed with H-steel joint material 6 and purlin materials 1 attached thereon, the roof is sloped when performing the roofing. A moving scaffold 5 is erected in the direction. Total length of H steel joint material 6 is 1
About 2m, 100m x 100m pitch on it
While the purlin 1 made of a square pipe of mm is attached by an angle-type bracket 7, the moving scaffold 5 is attached to the purlin 1
The traveling movement in the purlin direction is erected by a door wheel 2 that rides in the upper corner (FIG. 2). The length of the moving scaffold 5 in the direction of the slope of the roof is about 10 m, the width is about 2 m, and a stair scaffold 3 of about 500 mm in width is provided on one side over the entire length. As shown in FIG. 2, the stair scaffold 3 has a configuration in which flat plates are attached in a stair-like manner.
It is safe and agile in the direction of the roof slope, and can proceed with roofing work.

[0007] In the moving scaffold 5, the portion other than the stair scaffold 3 is configured as a cargo receiving space 4, and roofing materials, other materials, and parts are loaded into the cargo receiving space 4. Therefore, the roofing material and the like are always transported together with the movement of the movable scaffold 5, and are placed near the operator's hand. A handrail 8 made of a single pipe is installed on the side of the movable scaffold 5, and a worker performs a roofing operation by hanging a lifeline on the handrail 8.

According to the roofing method of the present invention, the moving scaffold 5 is erected at one end of the roof, and the moving scaffold 5 always precedes the roofing position and is operated in one unit. Stepping is performed sequentially in the direction of the purlin by width (usually about 1 m) in the purlin direction. Therefore, there is no need to temporarily provide any other scaffold.

In the illustrated embodiment, the movement of the moving scaffold 5 is configured to be manually pushed by an operator, but is not limited thereto. A motor is attached to the door wheel 2 as driving power,
It can also be implemented as a self-propelled type.

[0010]

According to the roofing method for a steep roof according to the present invention, the labor, cost, and time for assembling or replacing a scaffold can be omitted, and significant cost reduction and shortening of the construction period can be expected. Moreover, the labor for transporting the roofing material and the like can be omitted, and the worker can work while always riding on the movable scaffold 5, so that the safety is greatly improved. And since the worker does not have to walk on the already-covered roofing material, there is no need to worry about causing scratches or dents in the roofing material, and the roofing can be performed with excellent quality and accuracy.
