BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condominium, an apartment complex such as a housing complex, and a veranda for other middle and high-rise buildings,
In a building with a balcony, install it between the handrail such as a veranda and the elevator so that the elevator attached to the temporary scaffold outside the outer wall of the building at the time of building can enter and leave the balcony. The present invention relates to an elevator-compatible balcony mounting ramp.

[0002]

2. Description of the Related Art Conventionally, in order to move in and out between an elevator and a veranda of a frame, which are attached to a temporary scaffold outside a building, the ladder is placed on the slab of the veranda and the upper end of the handrail in an inclined state and grounded on the slab. The upper and lower ends of the ladder were fixed with jigs, number lines, etc., and the ladder was provided on the veranda side to form a passage between the elevator and the veranda, and to enter and exit.

However, the heights of the handrails on the veranda originally do not match, and it is not possible to use the same jig or fixture because the heights of the handrails are usually different. Since there is no suitable protrusion in the fixing source, it is difficult to fix with the above-mentioned working means, and there is a drawback that on-site alignment is required because the inclination degree of the ladder is not constant.

Further, even if the ladder can be attached to the veranda in an inclined manner, since the ladder is inclined even in the upper part of the handrail, simple and firm fixing is impossible and a fundamental solution is impossible. In addition, the tip of the slanted ladder is located above the handrails, which makes it difficult to install a horizontal landing and has a drawback in that it cannot perform a sufficient function as a passage.

As the ladder, it is also possible to use a retractable one. However, as such a retractable structure, a pair of both side rods on which a predetermined number of step stands are fixed are fixed on both sides on which a slightly narrow step stand is fixed. When the rods are mounted slidably and the expansion and contraction of both are adjusted and fixed, the type in which pins are inserted into the insertion holes penetrating the upper and lower rods at predetermined intervals and fixed, Even if it can be adjusted, it was not a stable solution when the slab had unevenness, and it was not a stable solution.

Further, there is a handrail protruding upward between the veranda and the elevator, and a considerable gap exists, a dangerous falling space is created between them, and even if the telescopic ladder is used, it is in an inclined state. Due to the predetermined pitch, there is a drawback that the optimum position of the ladder tip with respect to the elevator cannot be set.

Further, in a temporary passage using a ladder or a telescopic ladder, since there are problems of the fixing system and the horizontal part, a stepladder or a separate scaffold is mounted on the slab of the veranda,
Although a scaffolding board is installed between the tops of the handrail and stepladder, the heights of the tops of the handrail and stepladder do not match. It was impossible to obtain a high levelness, and there were still difficulties in fixing the scaffolding plate and the balcony.

[0008]

SUMMARY OF THE INVENTION According to the present invention, even if a handrail exists between an elevator and a veranda, a passage having a horizontal footboard that serves as a landing can be temporarily provided between the elevator and the veranda, and the upper portion of the handrail can be provided. It is intended to provide a balcony mounting ramp in which a horizontal step plate can be set at an optimal facing position with respect to an elevator.

[0009]

According to the present invention, in view of the problem that it is difficult to fix a ladder or the like and to set a horizontal portion at an upper portion of the handrail based on the above-mentioned conventional technique, the trumpet is fixed to the lower portion of the footboard with respect to the handrail. A stepping plate is fixed to the upper part of the handrail part of the veranda and a slide rod of the adjusting device is attached to the slab of the veranda by installing means and attaching an adjusting device capable of stepless adjustment to the lower end of the ladder part installed on the veranda side. Is installed in a stretched state, and then the landing state is stabilized by adjusting the amount of expansion and contraction of the slide rod in the adjusting device, and the footboard is brought into a horizontal state.

Further, in view of the problem that it is difficult to install the horizontal portion of the temporary passage at an appropriate position with respect to the elevator, an expandable retractable footboard is provided on the lower surface of the footboard so as to be movable back and forth with respect to the elevator, so that a space between the elevator and the handrail is provided. The above problem is solved by closing a part of the space.
