When it is difficult to build an external scaffold due to various reasons. 3. When carrying out curing work without restraining the on-site lifting machine.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. 1. External finishing scaffolding Despite the fact that scaffolding is not required, the method of assembling the external scaffolding for the purpose of curing is adopted. 2. As the construction of the building progresses, the entire outer scaffold is assembled to the final layer. 3. If it is a high-rise building, the height of the scaffold is limited, so a scaffolding stage will be installed on the way and the scaffolding will be assembled again. 4. A curing net, a curing frame, and a sheet are sequentially attached to the outer surface of the assembled scaffold. 5. For the gap between the external scaffold and the frame, attach a bracket to the scaffold, and install a curing plate on this to perform drop curing.

[0003]

The problems described in the prior art have the following problems. 1. External scaffolding for curing is absolutely necessary. 2. Requires external scaffolding on all sides. 3. The number of external scaffolds will be increased and increased according to the progress of construction. 4. Drop curing is also required at each construction stage.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following. 1. The product is divided into left and right parts so that it can be unitized and connected to the left and right in succession. 2. As a moving method, a moving roller is attached to the rising wall of the balcony, and the unit body is moved up and down by being guided by the moving roller. 3. The unit should be light enough to be hung with a chain block. 4. The present invention and the fall curing function from the gap between balconies are integrally incorporated into the present application. 5. Set the unit body in the height direction while covering about three layers including the constructed floor and the next constructed floor.

Since the present invention is configured as described above, it has the following effects. 1. It is possible to eliminate scaffolding assembly work for curing at a construction site using a PC balcony (factory-made concrete balcony). 2. The unit body can be easily moved up manually without using an on-site lifting machine. 3. The members can be produced at the factory and can be diverted and used in one assembly. 4. With three layers of curing material, all floors can be cured. That is, it is possible to satisfy about two floors of the already-constructed floor and the external curing of the floor under construction. 5. Since the curing plate 4D is attached to the falling curing unit 4 so as to be able to rise and fall, it is possible to prevent the curing plate 4D from falling through the gap between the building and the curing frame unit.
