EXECUTION METHOD OF CONCRETE SLAB AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To form a slab having a uniform lightweight structure in a short construction period by simplifying bar arrangement work of main reinforcements by completing the work at once without dividing the work, and surely fixing an embedded body to a fixed position. SOLUTION: The lower end main reinforcements 4a and 4b are longitudinally and laterally arranged in a form 2. Lower auxiliary reinforcements 7 are arranged in parallel to the lower end main reinforcements in an intermediate part of the mutual adjacent lower end main reinforcements of either one of the length and width. Upper end main reinforcements 5a and 5b are longitudinally and laterally arranged on the upper side of the lower end main reinforcements 4a and 4b with the prescribed height. The embedded body 6 composed of a lightweight material is arranged in a space partitioned by the upper end main reinforcements 5a and 5b and the lower end main reinforcements 4a and 4b. Upper auxiliary reinforcements 8 are arranged in the direction orthogonal to the lower auxiliary reinforcements 7 in an intermediate part of the mutual adjacent upper end main reinforcements. The embedded body 6 is supported from above and below by the upper auxiliary reinforcements 8 and the lower auxiliary reinforcements 7, and concrete is placed on the whole to form the lightweight slab.
