<P>PROBLEM TO BE SOLVED: To provide a concrete slab construction method capable of lightening and flattening a concrete slab; a reinforcement material support tool: a binding pin tool; and a lightening buried body. <P>SOLUTION: This reinforcement material support tool 100 is used when constructing the concrete slab; and has a sill member 110 capable of supporting a lower end reinforcement being a kind of reinforcement material, and an upper end reinforcement support member 120 installed on the sill member 110 and capable of supporting an upper end reinforcement being a kind of reinforcement material. While projectingly arranging a lower end reinforcement pressing-down shaft part 123 in an upper end reinforcement support member 122 for preventing swelling of the lower end reinforcement supported on the sill member 110, a support tool fixing male screw member 130 and a female screw part 111a for screw-fastening the sill member 110 to a template, are bored in the sill member 110. The female screw part 111a can threadedly engage by using both male screw members of a ceiling suspender fixing male screw member in common for screw-fastening a ceiling suspender to concrete after removing the template. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
