DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling scaffold used for building a column / beam structure.

[0002]

2. Description of the Related Art Conventionally, in the construction of a column / beam structure building, it is necessary to attach a work scaffold to a pillar and work on the scaffold at the time of joining a beam end to the pillar. Is being done. In addition, a ladder for climbing to the scaffold is attached to the side of the pillar. In this case, since the scaffold protrudes substantially perpendicularly to the side of the pillar, it is impossible to mount the scaffold horizontally, for example, on a truck bed or on the ground. Later, it is attached to the middle part of the pillar. The ladder and the scaffold are separately attached to the pillars.

[0003]

As described above, in the prior art, a scaffold was attached after a pillar was installed.
For example, the installation of this scaffold and other high-place work must be performed without a scaffold, and during that time, there is a disadvantage that the worker is forced to work in an unstable state.

[0004] Further, since the ladder and the tread for scaffolding are individually attached to the pillars, there is a drawback that the work becomes complicated accordingly.

According to the present invention, such a conventional disadvantage is solved, and a scaffold can be directly attached to a ground or a bed before erecting a pillar. In addition, a ladder and a tread for a scaffold can be mounted in the same bracket. It is an object of the present invention to provide a scaffolding device that facilitates the mounting operation by mounting the scaffold.

[0006]

Means for Solving the Problems In order to solve the above problems, the first invention of the present application is to vertically move along one side of a pillar.
Oriented brackets for mounting on the pole
On the ladder with
At least approximately at right angles to the column to the bracket
A tread that is rotatable between a parallel position and
Place the tread on the side that is perpendicular to the one side of the pillar.
And fixed so that it is maintained at a substantially right angle to the pillar
And fixing means .

[0007] Similarly, the second invention of this application is the first invention.
In the invention of the above, projecting to the side of the bracket or ladder
A rotary shaft of the tread plate is inserted into and attached to the cylindrical body .

[0008]

[Function] For example, even if the pillars are placed horizontally on the ground, if there is enough room to attach the bracket, install the treads so that they do not interfere with the ground, and rotate them to the formal state when erecting them. Just do it.

Also, by attaching the ladders, the brackets of the treads can also be attached, and the number of attachment steps is reduced as compared with the case where they are separately attached.
