Description

{MANUFACTURING METHOD FOR TWIN WALL}

The present invention relates to a method of manufacturing a twin wall, and more particularly, to a method of manufacturing a twin wall by applying a stirrup which connects a tension slab and a compression slab.

Typically, buildings are constructed either as PC products or as workplaces using formwork, or as components of maneuvering, walls, beams and slabs.

Since the columns and walls and the beams and slabs are constructed to support the pillars of the wall, it is possible to construct the walls by the non-load-bearing walls, thereby ensuring the economical efficiency of the wall. Further, So that it is possible to secure the economical efficiency of the slab.

However, since the pillars and the walls and the slabs of the pillars and the slabs of the pillars are installed, the pillars protrude into the interior of the building to occupy a space, resulting in a problem of poor space utilization. Moreover, Material cost, labor force, and the like.

In order to overcome the above problem, a recent structure is constructed as a bearing wall which does not have a column and a beam but a wall acts as a column, and a slab is also constructed as a slab, , It is possible to increase the space utilization while lowering the height of the floors.

In addition, in the above-mentioned prior art, mechanical connection using a coupler is performed because structural integration can be performed only when vertical reinforcement is continuously connected when the slab and the load bearing wall are connected by being laid.

However, when a mechanical joint using such a coupler is performed, there is a problem that work efficiency is lowered in the process of serializing vertical steel bars to achieve structural integration, and a considerable amount of time and worker's labor is required additionally.
