Description

A pre-assembled column with a formwork and a band in one piece {LARGE SIZE FORMING ANGLE COMPOSITE HAVING BAND}

The present invention relates to a prefabricated post, and more particularly, to a preassembled post having a formwork and a band integrally.

The construction industry can be broadly divided into reinforced concrete structure, steel frame structure, and steel frame reinforced concrete structure.

The most commonly applied reinforced concrete structure is a construction method that uses only concrete and reinforcing bars to directly construct on-site, and also directly installs the formwork on site to pour concrete. However, almost all of the work and costs occur on site, and the construction period is the longest among the above three construction methods and is greatly affected by the weather. In addition, there is a high dependence on on-site manpower and the recent increase in the labor cost of rebar and carpenters has made it difficult to supply and demand manpower.

In the case of steel structure, it has the advantage of shortening the construction period because the influence of weather can be minimized due to the factory production of steel members and the dry construction method on site. This is a high technique.

Reinforced concrete structure can be said to be the fusion of steel frame structure and steel frame concrete structure. It is a construction method that can make the most robust structure by supplementing structural disadvantages that cannot be solved with steel frame alone. However, there are still disadvantages in that the use of steel frames increases the construction cost, and the need to install a formwork and pour concrete on site.

Therefore, there is a growing need for a method that can be effectively applied to the field by combining the advantages of the above methods and combining heterogeneous parts between each process.

Currently, the construction market has more bad news than good news, such as a serious manpower shortage and instability of raw material prices.

For this reason, the dominance of the construction market is gradually changing into construction methods that can simplify construction methods and minimize the input of manpower in the field, that is, structures or products that can be manufactured in a factory and constructed simply and quickly. Among the various types of construction methods created for the above reasons, there are many products and construction methods in the form of pre-assembly in which columns are produced and constructed in factories.

The rebar prefabricated column construction method can satisfy two conditions: the economic feasibility of reinforced concrete columns and the constructability of the steel structure. However, in order to reduce the demand for manpower, a formwork band-integrated pre-assembly structure is required because the conventional rebar pre-assembly column construction requires the installation of a formwork, and a large number of manpower is still required to install and remove the formwork.
