PROBLEM TO BE SOLVED: To provide a truss composite floor slab which is easy for handling during storage or transportation or the like, and is ready for assembling after being carried in the site. SOLUTION: The truss composite floor slab includes a PCa floor slab 2 and a plurality of truss reinforcements 3 projected on the concrete construction joint surface 2a of the PCa floor slab 2. An embedding insert 4 is embedded in the concrete construction joint surface 2a of the PCa floor slab 2. The truss reinforcement 3 comprises an upper-end reinforcement 3a, a plurality of lower end reinforcements 3b, 3b and a plurality of lattice reinforcements 3c arranged between the upper-end reinforcement 3a and lower end reinforcements 3b, 3b, and formed into a three-dimensional truss form having substantially a triangle cross section. The lower end reinforcements 3b, 3b of the truss reinforcement 3 are attached to the concrete construction joint surface 2a of the PCa floor slab 2. The lower end reinforcements 3b, 3b of the truss reinforcement 3 are secured to the concrete construction joint surface 2a of the PCa floor slab 2 with a plurality of lower end reinforcement grasping tools 5 and fixing bolts 6. The fixing bolts 6 are screwed with the embedding inserts 4. COPYRIGHT: (C)2011,JPO&INPIT |
