Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ladder support structure.

[0002]

2. Description of the Related Art Conventionally, a ladder anti-slip device for preventing a ladder standing on an outer wall surface of a building from sliding down has been disclosed in Japanese Patent Application Laid-Open No. 7-1995.
No. 158366. The anti-skid device of the ladder described in the above publication has an attachment body attached to the ends of the left and right pillars constituting the ladder, and an anti-slip seat plate swingably coupled to the attachment body, and stands the ladder. When
The anti-slip seat plate contacts the wall of the building to prevent the ladder from sliding down.

[0003]

However, although the ladder anti-skid device described in the above publication can prevent the ladder from sliding down, it does not fix the ladder to the wall surface, so that the ladder does not slide down reliably. There is no guarantee. In addition, when a ladder is erected on a roof eaves or the like and climbed on the roof, there is a problem that the effect cannot be exhibited because the anti-skid seat plate is separated from the wall surface of the building.

[0004] When mounting an antenna or the like on a sloped roof, there is a case where a scaffold is not installed. In this case, a ladder is set up on a wall and the roof is climbed. However, there is a safety problem due to the extremely high risk depending on the weather, such as when the roof has a steep slope such as a 6-dimension slope, or when it is raining or when frost is falling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a ladder support structure for surely preventing a ladder installed on an outer wall surface or a roof surface from sliding down. I have.
