Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to condominiums, condominiums, condominiums,
At the time of construction of a building with a balcony, it relates to a temporary scaffolding and a veranda mounting ramp which is constructed such that a passage corresponding to a temporary building outside the building, such as an elevator attached to the temporary scaffold, is installed between the building and the veranda. is there.

[0002]

2. Description of the Related Art Conventionally, passages between a veranda, a scaffold, and a temporary object such as an elevator attached to the scaffold have individual problems as described later. Therefore, different types of ramps were required for each case.

[0003] For example, access between the veranda on the skeleton side and the scaffold outside the building is performed by fixing a stepladder having a tread plate at the center of the top part on a slab of the veranda and a frame pipe appropriately selected from the scaffold constituting frames. Also, when entering and exiting between the veranda and the elevator, a horizontal step board is provided on the handrail of the veranda, and a ladder portion is provided on the veranda side and the scaffold side, so that a passage is formed between the veranda and the installed object. Was.

[0004] However, the tiers of the veranda and the scaffold do not coincide with each other, and the height of the handrail of the veranda varies depending on the site, so that a passage corresponding to the site must be assembled and installed each time.

More specifically, when a passage is formed between a veranda and a scaffold, a stretchable stepladder is used, and as a stretchable structure of the stepladder, a pair of both side rods having a fixed number of steps are fixed. A two-sided rod with a narrow step base fixed is slidably attached, and when adjusting the expansion and contraction and fixing of both, a pin is inserted into each of the insertion holes penetrated at predetermined intervals in the upper and lower both-side rods and fixed. Things were used.

However, since it is unstable to simply install the stepladder between the veranda and the scaffold, it is necessary to fix the lower end of the ladder portion to the frame pipe on the side of the scaffold.
As described above, the amount of expansion and contraction of the ladder part of the stepladder is stepwise, and when attaching the ladder part to the scaffold side,
Careful setting of the vertical position of the frame pipe on the scaffold side is necessary so that the tread plate on the upper part of the stepladder is horizontal, and the usual stepladder is made of iron and has a considerable weight. The mounting operation had the drawback of being difficult.

[0007] Next, in the ladder portion for forming a passage between the veranda and the elevator, the same jig and fixing device cannot be used, or there is no appropriate protrusion at the fixing source. However, there is a disadvantage that the ladder needs to be adjusted on site because the inclination of the ladder is not constant.

Further, even if the ladder can be attached to the veranda in an inclined manner, the ladder is inclined even at the upper part of the handrail, so that simple and firm fixation is impossible and a fundamental solution is impossible. In addition, since the tip of the ladder that is inclined above the handrail is located, it is difficult to set up a horizontal landing and has a drawback that the function as a passage cannot be sufficiently performed.

Further, a ladder that can be extended and contracted can be used, and the ladder has the same construction as that of the stepladder described above. However, even if the inclination can be adjusted, the slab can be used. In the case of irregularities where there are irregularities in the
The stability was poor and could not be a fundamental solution.

In addition, there is a handrail projecting upward between the veranda and the elevator, and a considerable gap exists between the veranda and the elevator. Because of the predetermined pitch, there was a drawback that the optimum position of the ladder tip relative to the elevator could not be set.

In addition, in the temporary passage using a ladder or a telescopic ladder, since there are problems of a fixed system and a horizontal part, a stepladder or a separate scaffold is assembled on a slab of a veranda.
A scaffold plate is used between the handrail and the top end of the stepladder, etc., but the height of the handrail and the stepladder do not match in this case as well. It was still impossible to obtain a high degree of horizontality, and it was still difficult to fix the scaffold and the veranda.

[0012]

SUMMARY OF THE INVENTION According to the present invention, there is provided a means for overcoming a handrail from a veranda, by selecting and attaching fixing and connecting means corresponding to each temporary object such as a scaffold outside a building and an elevator. It is another object of the present invention to provide a veranda mounting ramp which allows a passage corresponding to a temporary object to be erected between them.

[0013]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and the path between the temporary object and the veranda conforms to each site because the type of the temporary object, the height of the handrail, and the like differ depending on the site. In view of the issues that must be formed each time, the veranda side consisting of treads and ladders,
Either a scaffold fixing main body having a fixing means to a scaffold or a handrail fixing main body having a handrail fixing means is selected and mounted, and an adjustment device which can be continuously adjusted at a lower end of a ladder portion to be installed on a veranda side. By fixing the tread plate on the upper part of the handrail of the veranda, installing the slide bar of the adjustment device on the slab of the veranda with the slide bar extended, and then adjusting the amount of expansion and contraction of the slide bar in the adjustment device, the landing state And stabilizing the footprint, and making the tread plate horizontal to solve the above problem.

More specifically, the scaffold-side ladder is provided with a ladder portion provided with a clamp at the lower end of the scaffold fixed to the tread plate, and a tread plate provided at a predetermined interval above the handrail portion of the veranda. The part is fixed to the frame pipe of the scaffold, and the tread plate is set horizontally by adjusting the amount of expansion and contraction of the slide bar in the adjusting device to construct the passage.

Further, the handrail fixing main body mounts a fixing portion of the veranda to the handrail on the tread plate to fix the tread plate above the handrail portion of the veranda, and adjusts the amount of expansion and contraction of the slide bar by the adjusting device to set the tread plate. Is horizontal, and a telescopic tread is provided below the tread so as to be able to advance and retreat with respect to the elevator, thereby closing a part of the space between the elevator and the handrail and constructing a passage.
