Detailed Description of the Invention

[0001]

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 equipped with a balcony, a scaffolding temporarily installed outside the outer wall of the building at the time of construction is installed between the scaffolding and the skeleton such as a veranda so that it can enter and leave the balcony. In the ramp for
The present invention relates to a structure for connecting safety frames in a balcony mounting ramp that ensures the safety of a temporary passage.

[0002]

2. Description of the Related Art Conventionally, in order to move in and out between a scaffold temporarily installed on the outside of a building and a veranda of the skeleton, a stepladder with a step board at the center of the top is fixed to a frame tube appropriately selected from the slab of the veranda and the scaffolding frame. Then, a horizontal footboard is provided on the handrail of the veranda, and a ladder portion is provided on the veranda side and the scaffold side to form a temporary passage between the scaffold and the veranda to enter and leave.

However, since the floors of the veranda and the scaffold do not normally coincide with each other, a stretchable one is used as the stepladder. As such a stretchable structure, a step stand having a predetermined number of steps is fixed. A pair of both side rods are slidably attached to both side rods with a slightly narrow step base fixed.When adjusting the expansion and contraction of both, the upper and lower rods are fitted with pins in the insertion holes formed at regular intervals. The ones that were inserted and fixed were used.

Further, 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 tube on the scaffold side, and as a result, as described above. Due to the fact that the amount of expansion and contraction of the ladder part of the stepladder is gradual, when installing the ladder part to the scaffolding side, carefully adjust the vertical position of the frame tube on the scaffolding side so that the footboard on the upper part of the stepladder is horizontal. Since such a stepladder is made of iron and has a considerable weight, it is difficult to attach the stepladder.

Therefore, the applicant of the present application attaches a pair of ladders to the front and rear sides of a rectangular tread, provides a clamp at the lower end of the ladder fixed to the scaffolding frame of the scaffold, and lands on the slab of the veranda. A pair of slide rods having a grounding portion are arranged under the pair of side rods of the ladder portion so as to be independently movable, and the height of the slide rods can be adjusted steplessly and fixed. In this way, we have developed a balcony mounting ramp with an adjusting device that has means for fixing the slide rod to the side rod of the ladder part.

Simultaneously with the development of the above-mentioned balcony mounting ramp, the treads and ladders of the ramp are arranged in the space between the scaffold and the balcony, and the worker must move the ladder up and down to pass. In addition, since the taffle to the scaffold is in an orthogonal state, the walking state becomes unstable especially when transporting materials.Therefore, attach a safety frame to both upper sides of the taffle and the veranda side of the scaffold to which the taffle is attached. I thought

[0007] However, as the level of the scaffold is not the same as the level of the veranda, the level of the trap is not the same as that of the scaffold. It became clear that the safety frame could not be installed or that the safety frames connected to both sides needed to be devised.

For example, since the connection state of the taff safety frame provided on the trump and the scaffold safety frame provided on the scaffold are orthogonal to each other and vertical movement adjustment is required, the taff safety frame is made of, for example, a metal oval ring. If the frame pipes of the scaffolding safety frame are connected to each other, the slidability and the rotatability between the two are impaired, and smooth assembly, installation, and withdrawal are difficult.

Further, since the temporary passage between the scaffold and the ramp is in an orthogonal state having a step, it is assumed that the material may damage the safety frame when the material is transported and the safety frame is not robust. However, it has a drawback of requiring exchangeability and workability of the safety frame itself and its connecting portion, which is contrary to the reasonably required requirements.

Furthermore, it is also necessary to consider that the innumerable single component frames of the scaffold are not common and have the same size, and the workability at the time of exchanging the taff safety frame or the scaffold safety frame with respect to the trump or scaffold. Was.

[0011]

SUMMARY OF THE INVENTION According to the present invention, even if the height of the scaffold is different from that of the veranda, a temporary passage can be formed between the scaffold and the veranda, and the level of the footboard can be easily set. In a taff for use with a veranda, the taff safety frame and the scaffold safety frame can be easily attached to the scaffold and the taff that are arranged in the orthogonal direction and have different heights, and the exchangeability at the time of damage is improved. It is intended to provide a connection structure of safety frames in.

[0012]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and in view of the problem that the positional relationship between the scaffolding safety frame and the scaffolding safety frame attached to the scaffolding is complicated and the connecting structure is burdened, the trapping safety frame is provided. In the connecting bracket for connecting the scaffolding safety frame with the scaffolding safety frame, by inserting the synthetic resin ring body into the two cylindrical holding portions, and by inserting the side frame pipes of the trap safety frame and the scaffolding safety frame into the ring body, The synthetic resin ring body ensures smooth movement of the side frame pipes, and the trap safety frame and scaffolding safety frame are installed in a specific positional relationship.

Further, in view of the problem that the taff safety frame or the scaffold safety frame on the side of the scaffold or the ramp is damaged due to the collision of materials and needs to be replaced, nuts are provided at the upper and lower ends of the side frame pipes of the scaffold safety frame, The problem is solved by providing a bolt at the base end of the lateral frame pipe of the scaffolding safety frame so that the taffle safety frame and the scaffolding safety frame can be separated.
