Description

Technical Field [0001] The present invention relates to a twist construction method for an irregular building structure,

The present invention relates to a method of twisting a steel structure of an atypical building structure, and more particularly, to a method of twisting a steel structure of an atypical building structure capable of forming a steel structure, ≪ / RTI >

Generally, the concrete structures that make up the framework of buildings such as houses are divided into the reinforced concrete structure, the steel structure, and the tree structure.

The reinforced concrete structure is formed by building the skeleton of the building with reinforcing bars, making the form using wood or steel plate around the skeleton, filling the concrete formed with the form, and curing.

In addition, a steel structure is formed by connecting a metal steel (H beam) to form a skeleton of a building, spraying and curing concrete on a steel material, and then forming a wall using a sandwich panel or the like.

In addition, the wooden structure is composed of walls and roofs made of wood as a main material, and can be seen in traditional houses such as hanok. In recent years, there is a tendency to construct nature-friendly houses, Trend.

However, the reinforced concrete structure is disadvantageous in that when the reinforcing steel is corroded by moisture or the like, the bonding strength with the concrete is weakened and the structure is weakened. Also, since a large amount of form is used at the time of construction, the construction period is long and the construction cost is high. There is a problem that the process is very complicated, such as collecting and processing.

In addition, the wood structure can shorten the air compared to the reinforced concrete and does not require an auxiliary material such as a formwork, but has a problem that the construction cost is excessively required because the material cost of wood and the like is high.

In recent years, the number of atypical architectural structures has increased more than the standardized architectural structures. This is due to the cultural and technological symbolism of irregular architectural structures, the development of information technology (IT) and the building information modeling (BIM) The introduction of technology, and the development of construction technology.

The proportion of these unstructured building structures is steadily increasing worldwide. The proportion of unstructured building structures, which were about 10% in the early 1990s, increased to about 25% in the latter half of 2000, The proportion of building structures is expected to increase more and more.

However, unstructured architectural structures so far have suffered from difficulty in designing and high construction cost in construction and construction, which made construction difficult.

Particularly, since the irregular building structure has many errors in the assembling process after forming the frames formed in various shapes, there is a problem that the working time and cost are increased and the shape of a certain portion is changed.
