Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-sided scaffold used for a construction site of a building having a veranda or the like.

[0002]

2. Description of the Related Art One-sided scaffold is a small scaffold temporarily installed on a construction site of a building where a veranda or the like is provided, and has a structure in which a simple work passage is provided on each floor for construction of the building. is there.

Conventionally, various assembling methods and structures of the one-sided scaffold are known.

For example, (1) a method of assembling a one-sided scaffolding on a lower veranda for each floor and sequentially constructing a next upper-floor balcony, and a one-sided scaffold of a structure are known. This is a method of attaching to the lower formwork of the balcony on the upper floor, making one side scaffolding of each floor on the side, or supporting from the lower floor with a support rod to build the upper floor one by one.

Further, (2) a rod body standing upright so as to contact the side wall surface of the balcony on each floor, and a handrail frame body standing upright in parallel with this are provided, and a work scaffold is hung between them. I knew how to give it.

[0006]

However, the conventional one-sided scaffold has various problems. For example, in (1), after creating the lower veranda, it was necessary to sequentially attach the handrail frame support bracket to the lower formwork of the upper veranda. This installation is very troublesome, and there is a problem that it interferes with the construction of the formwork.

Further, in the case of the one-sided scaffold as in (1), since it is necessary to set up a support rod on the veranda on the lower floor and support the lower surface formwork of the upper floor, the floor with the support rod is There was a problem that it hindered the use of the balcony.

Further, as in (2), the rod standing upright so as to be in contact with the side wall surface of the veranda is fixed by bolting it from both sides so that the mounting portion between the rod and the veranda straddles the upper part of the veranda. It was Therefore, there is a problem that the strength is very weak, and there is a problem that an auxiliary member such as a reinforcing material for strengthening the strength is required.

Therefore, in these conventional examples, there is a problem that it takes time to assemble and disassemble the one-sided scaffolding, and it takes a relatively long time for the construction work of the exterior structure.

It is an object of the present invention to obtain a one-sided scaffold which has strength without requiring a reinforcing material and can be assembled and removed at an early stage.
