Advantages of PC

  • The modular construction method can reduce the construction period by 30% or more on average compared to the existing method (RC)

  • When constructing a building that requires a high load, it can reduce costs by reducing the cross-sectional area of members by introducing pre-tension and reducing the amount of materials such as temporary materials and molds

  • High quality can be secured by pre-fabrication of members in a factory with optimal production conditions

  • Maximization of mechanized work during construction reduces the number of on-site workers and secures safety

  • Optimized for urban construction with dense population and buildings due to low noise and dust generation

Introduction of production products

  • 전단 더블월(I.D.W)
    전단 더블월(I.D.W)

    IS DONGSEO DOUBLE WALL(I.D.W)

    It is an innovative double wall that enhances durability and reduces the cross-section thickness by 100mm compared to the existing double wall by using a mixture of shear reinforcing bars and reinforcing materials that connect the panels (walls). As the thickness is reduced, cost reduction and productivity can be expected.

  • 중동기둥
    중동기둥

    Hollow column

    These are two types of hollow columns in which hollow parts are made of duct / steel plate. Unlike the existing hollow column, it is an efficient column that can secure more than 50% of hollowness by replacing the main middle bar with a square pipe.

  • 지화외벽
    지화외벽

    Basement outer wall

    It is an exterior wall construction method that for an integrated wall by embracing columns rather than ‘pillar-external wall-pillar’. If the basement external wall that resists earth pressure is applied as a PC member, it can be constructed quickly and accurately and shorten the construction period by increasing productivity.

  • 장경간 슬라브(역리브형)
    장경간 슬라브(역리브형)

    Long span slab (reverse rib type)

    It is a slab that forms a slab without inserting a separate material in a hollow part, secures a Topping Con’c filling space, and implements an unshored Deck system by increasing rigidity.

    Patent No. 10-0009911

  • 단경간 슬라브(리브형)
    단경간 슬라브(리브형)

    Short span slab (rib type)

    This slab is implemented to minimize the amount by forming a hollow part divided by the lower ribs, and to distribute the concentrated load on the ribs by forming inclined surfaces at both ends and to prevent concrete leakage when pouring the Topping Con’c.

  • 프리캐스트 구조물 전용 접합철물(기계적이음)
    프리캐스트 구조물 전용 접합철물(기계적이음)

    Bonding hardware only for precast structures (mechanical joint)

    As a coupler that can overcome production/assembly errors that may occur in the connection of PC members, rather than rebar joint of the general RC method, it is suitable for one-to-one joint seismic structure.
