Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story detached house having a concrete bearing wall structure having no concrete slab for partitioning each floor, that is, a multi-story detached concrete house in which the first floor to the top floor is a single residence.

[0002]

2. Description of the Related Art In a multi-story concrete house represented by a conventional condominium, an outer wall structure having a rigid frame structure with structural columns and beams is constructed on the foundation of a concrete bearing wall structure, and the inside of the outer wall structure is It has a structure in which each floor is partitioned by a slab of a concrete load-bearing wall structure, a floor structure made of wood or steel is constructed on the concrete slab, and a partition wall is provided on the floor structure, and each space is partitioned by a slab. A single or multiple residential doors are formed inside.

[0003]

However, in the above-mentioned multi-story concrete house, the renovation is limited to the renovation of each floor separated by the concrete slab, and the renovation of the internal space ignoring the concrete slab, that is, the upper and lower spaces. It is very difficult to freely modify or completely modify the interior space of the outer wall structure.

Further, the outer wall structure itself is unduly made into a concrete structure having a large cross-sectional area and high weight, resulting in a longer construction period and an increase in construction cost.

[0005]

According to the present invention, the degree of freedom in designing floor assembly and partition walls in an outer wall structure is increased, and the upper and lower floors can be easily renovated in response to generational changes and changes in life cycle. We provide multi-story detached concrete houses.

[0006] In addition, a multi-story detached concrete house in which the construction period and construction cost are greatly reduced while having durability and fire resistance by concrete construction, that is, a multi-story detached concrete house in which the first floor to the top floor is a single residence provide.

In summary, the present invention constructs a box-shaped outer wall structure having a concrete bearing wall structure on a foundation, and causes the box-shaped outer wall structure to bear the building strength required by the construction method. Adopting a building style in which the floor structure of each floor made of wood or steel frame that can be laterally supported by the outer wall structure inside the structure is constructed, and the floor structure and partition walls within the box-shaped outer wall structure can be freely constructed, So that it can accommodate various renovations.

As another example, a box-shaped outer wall structure having a concrete load-bearing wall structure is constructed on a foundation, and each of the corners in the box-shaped outer wall structure is provided with the structure and an integral concrete structure column. The box-shaped outer wall structure is formed by annularly projecting a structural beam integrally formed with the same structure on the inner peripheral surface of the box-shaped outer wall structure so that the box-shaped outer wall structure bears the building strength required by the construction method. Inside the outer wall structure, a floor frame of each floor is constructed by a wooden structure or a steel frame that can be laid across the structural beams of the outer wall structure.

As a result, it is possible to freely construct floors and partition walls in the box-shaped outer wall structure, and thus to freely and variously remodel.

Further, according to the above, there is provided a multi-story detached concrete house in which the construction period and the construction cost of the conventional reinforced concrete multi-story house are significantly reduced.
