Description

PC (Precast Concrete) Rego Type House}

The present invention relates to a legged type PC house. More specifically, the present invention relates to a legged type PC house, in which a lower structure having upper and lower openings is placed on an upper part of a backing structure made of concrete, a lower body is laid on the backing structure and lower structure, And the upper structure is placed on the upper part of the frame.

Generally, in construction of houses and buildings, first of all, the ground to be constructed is dug up and the construction work is carried out. Then, after constructing the ground using concrete in the space where the construction work is done, Depending on the structure of the building, an inner and outer formwork with reinforcement inside is installed.

When the inner and outer molds are installed, the concrete wall is installed by inserting the concrete into the inner and outer molds. After the wall is constructed, the cured concrete is cured for a sufficient time. When the concrete is cured, The construction work for the ceiling slab of the rebuilt wall is carried out, and the basic structure of the house or building is completed through the process of pouring and curing the concrete in the ceiling slab formwork.

In addition, when the basic structure of the building is completed, interior and exterior walls of the building are closed using bricks and other internal and external materials, and other electrical wiring and water pipes are constructed, and then the house is completed.

The construction of a house or a building made by such a construction method must be carried out, for example, by installing an inner or outer formwork or placing reinforcing bars in the inner and outer formwork, pouring concrete, or curing the poured concrete The construction period of the house is long.

A prior art for solving such conventional problems is disclosed in Japanese Patent No. 10-1410602 entitled " Method of Laminate Construction of Monolithic Structures of Concrete Housing ".

This prior art discloses a monolithic structure construction method of a concrete house. When a unit concrete structure is laminated on a foundation floor, the upper and lower surfaces of the unit concrete structures stacked when the unit concrete house is constructed in multiple layers are simply anchored And the bolts are combined with each other, so that the multi-layered unit concrete structures can be improved in durability as well as in durability, and the concrete structure made of the unit can be directly assembled without placing the concrete in the formwork and the installed formwork In addition to the construction period, it is possible to simplify the house construction and to shorten the construction period, as well as to make the connection work by stacking the concrete structures made of monoliths simple. Up efficiency can be greatly improved.

However, in such a prior art, it is not easy to form a concrete structure in which a left side, a right side, an upper side, and a bottom side are integrally formed and the front and rear sides are opened to provide space, And holes are formed in the upper and lower surfaces of the upper and lower surfaces of the upper and lower plates, respectively, and the upper and lower surfaces are bolted together by an anchor body and a nut.
