BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-cast wall structure,

The present invention relates to a multi-precasted wall structure and a method of constructing the same. More specifically, the present invention relates to a multi-precasted wall structure and a method of constructing the same, And more particularly, to a multi-cast wall structure and a method of constructing the same.

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.

Korean Patent No. 10-0211534 filed on Feb. 24, 1997, entitled "PC wall and PC slab connection structure of building and construction method thereof" Korean Patent No. 20-0303948 filed on November 12, 2002, entitled "Structure of concrete wall and slab construction formwork"

In order to solve the above problems, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a multi-precast wall structure for placing a concrete slab between a forked concrete and a precast wall after placing the precast wall on top of the foreclosed concrete, .

In particular, the technical problem to be solved by the present invention is to form a space between the outer concrete and the base plate through the vertical connection bar installed perpendicularly to the base plate and to insert the lower slab into the concrete, And a method of constructing the same.

It is another object of the present invention to provide a multi-precast wall structure and a method of constructing the same that improve the structural stability by providing a reinforcing member connecting the first wall and the second wall.

As a means for achieving the above-mentioned technical object, a multi-precast wall structure according to the present invention comprises: a truncated concreted concrete; A precast wall positioned at both upper ends of the abandoned concrete by a crane; And a lower slab including a lower slab reinforcement disposed in a space formed between the abandoned concrete and the precast wall, and a lower slab concrete inserted in concrete in the lower slab reinforcement, wherein the precast walls are opposed to each other And are located at the upper ends of both sides of the abandoned concrete.
