Description

{Pulling up Locking Device of a Mold}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette ring device, and more particularly, to a lifting cigarette ring device used for lifting a cushioning foam used for constructing an outer wall at a construction site.

Generally, when a high-rise building or an apartment is constructed, gang-foam is used in a large-sized mold to be installed outside. This represents a formwork system in which the form is enlarged and installed and disassembled at once.

Such gauze consists of a steel formwork installed to construct the outer wall and a work footrest, a workbench, a handrail and connecting parts for working outside.

The gang form is applied to each shape according to the shape of the building, and the weight of one gang is usually 2 ~ 4 tons, and the width is 3 ~ 12M and the height is 9M.

This will be repeatedly used for lifting and installation using a tower crane installed on site.

After the curing is completed by using gum placed on the outside and a Euro or al foam installed on the inside, it is necessary to disassemble the above-mentioned suspended forms and move to and install it on the upper layer.

In case of external gang form, the wire connected to the tower crane and the shackle installed on the tower crane are fixed to the lifting ring installed on the gang form, then the gang form fixing bolt installed on the outside is dismantled and the gang form is lifted. And the gang form is fixed.

The lifting operation of the gang-foam is performed by repeating the above-mentioned method. It is possible to disassemble all the outer bolts before fixing the lifting hook of the gang-form to the tower crane due to the operator's convenience or carelessness, And safety accidents in which the worker falls together due to the fall of the gantry are frequently occurred.

On the other hand, a lifting ring for lifting is required in the conventional gang foam, euro foam, or al foam. Such lifting rings are used by forming a lifting ring by a work such as welding every time each work is performed.

As described above, since the work process for forming the lifting ring for every work such as the gum, the euro foam or the alum, the cost is wasted, and the human and the temporal damage are considerable.
