Abstract
A timber-concrete composite slab with a notched plywood shear connector may include a plurality of shear connectors disposed with gaps in a width direction, and a plurality of tension members made of wood and each coupled to lower portions of any one and another adjacent one of the shear connectors between the adjacent shear connectors. The timber-concrete composite slab may also include a plurality of heat insulators each bonded or inserted between upper portions of any one and another adjacent one of the shear connectors, and concrete poured in a predetermined height over the shear connectors.
Claims10
A timber-concrete composite slab with a notched plywood shear connector, the timber-concrete composite slab comprising:
- a plurality of shear connectors, each of the plurality of shear connectors formed by longitudinally connecting a plurality of plywood sections, wherein each of the plurality of plywood sections has a notched portion on an upper end;
- a plurality of tension members made of wood, each of the plurality of tension members coupled to lower portions of any one of the plurality of shear connectors and another adjacent one of the plurality of shear connectors between the adjacent shear connectors;
- a plurality of heat insulators, each of the plurality of heat insulators coupled to upper portions of any one of the plurality of shear connectors and another adjacent one of the plurality of shear connectors between the adjacent shear connectors;
- and
- concrete poured in a predetermined height over the shear connectors.
A method of manufacturing a timber-concrete composite slab with a notched plywood shear connector, the method comprising:
- forming a notched portion by partially cutting each of a plurality of plywood sections having identical dimensions in width and depth;
- forming a shear connector by longitudinally arranging the plurality of plywood sections having the notched portions formed thereon;
- coupling a wood tension member having a predetermined height to the shear connector by butting and the nailing the tension member to a lower portion of a first side of the shear connector;
- coupling an heat insulator having a predetermined height to the shear connector by joining and then fixing the heat insulator to an upper portion of a first side of the shear connector having the tension member fixed thereto;
- connecting shear connectors in a preset width by joining and then nailing a shear connector to the shear connector having the heat insulator coupled thereto;
- and
- pouring concrete over the shear connectors connected in the preset width.
