Gang form lifting device and outdoor wall construction method of building using the same}

The present invention relates to a gangform lifting device and a method of constructing an exterior wall of a building using the same, and more specifically, to a gangform installation step, a gangform raising step and a concrete pouring step for an extension of an exterior wall of a building by easily performing a building The present invention relates to a gang form impression device that can shorten the construction time of the outer wall of the building, and a construction method of the exterior wall of the building using the same.

In general, the outer wall of the building is constructed by using a formwork such as gangform, because the formwork can not cover the entire outer wall of the building according to its size and weight, usually installed on one floor after the outer wall, The formwork is raised and the outer wall of the upper layer is constructed.

At this time, the tower crane is conventionally used to raise the formwork. Tower crane is a high lift crane that is mainly used for high-rise construction. It is frequently used in skyscrapers or apartment construction sites. When manpower is used, many people and time are required, so tower cranes and rebars, equipment and electricity, etc. necessary materials and materials can be easily transported to the upper part of the vertical tower.

However, when using such tower cranes, accidents related to installing, dismantling, and raising tower cranes, such as serious disasters caused by the tower cranes, account for about half of the total, and the high cost of using cranes. This problem occurs, and recently, a gangform raising device is being developed to replace tower cranes to raise formwork such as gangforms for building buildings.

As such a formwork for replacing the tower crane as a formwork lifting device has been proposed through the conventional "Registration Utility Model 20-0241872".
