Truss girder

  • A truss girder serves as a reasonable SHEAR CONNECTOR between the cast-in-place concrete and the assembly (PC) plate. It is composed of three members – the upper bar, lower bar, and truss bar (lattice bar) – and the contact points of each member are integrated through electric resistance welding.

Application of the truss girder

  • Among the construction production methods, there is the assembly (PC) method, and the HALF SLAB method – a method that overcomes the problems that occur in the assembly (PC) method, and utilizes the advantages of assembly.
  • This is intended to facilitate the jointing of members through partial Precastization, and to develop the technology as an extension of the conventional, on-site cast-in-place reinforcement bar concrete construction.
  • The HALF SLAB method also serves as a formwork. Therefore, the upper bar and truss bar of the assembly bars are derived from the assembly (PC) flat plate and are formed by the cast-in-place concrete on top of it.
