LIGHTWEIGHT CONCRETE FLOOR SLAB AND LIGHTWEIGHT CONCRETE FLOOR SLAB CONSTRUCTION METHOD
To provide a lightweight concrete floor slab reduced in weight without requiring the use of lightweight concrete as an essential condition, and a construction method for the lightweight concrete floor slab reduced in construction labor and cost.SOLUTION: In a lightweight concrete floor slab 110, a plurality of hollow molded bodies 10 is buried inside a concrete 50 in which rigid long members are arranged. The lightweight concrete floor slab construction method includes a lower layer reinforcement arrangement step for arranging reinforcement of a lower layer (a lower layer reinforcement 44), a hollow molded body arrangement step for arranging the hollow molded bodies 10 above the lower layer (the lower layer reinforcement 44), and an upper layer reinforcement arrangement step for arranging reinforcements of an upper layer (an upper layer reinforcement 24) positioned above the lower layer (the lower layer reinforcement 44), which are sequentially performed, and then a placing step for placing the concrete 50 is performed.SELECTED DRAWING: Figure 2
【課題】軽量コンクリートの使用を必須の条件とすることなく軽量化が図られた軽量コンクリート床版および構築の労力および費用が低減された軽量コンクリート床版の構築工法を提供する。【解決手段】軽量コンクリート床版１１０は、剛性の長尺部材が配筋されたコンクリート５０の内部に複数の中空成形体１０が埋設されており、軽量コンクリート床版構築工法は、下層（下層鉄筋４４）の配筋を行う下層配筋工程、下層（下層鉄筋４４）より上方に中空成形体１０を配置する中空成形体配置工程、および下層（下層鉄筋４４）より上方に位置する上層（上層鉄筋２４）の配筋を行う上層配筋工程を順に実施し、次いでコンクリート５０を打設する打設工程を実施する。【選択図】図２
