ート部材。 The rib part and the lower half of the slab are made in a continuous formwork with a single or double T-shaped cross section, and the lower main material is made of double reinforcing bars. An assembled reinforcing bar truss made of lattice reinforcing bars is placed perpendicularly to the rib section, and a concentrated load is applied until the truss bars become horizontal.
While maintaining this state, concrete is poured into the majority of the truss, and strength is developed through steam curing, etc.
A semi-precast concrete member reinforced with prestress introduction and reinforced steel truss for unsupported slab construction, characterized in that the load is released and prestress is introduced.
