PRECAST CONCRETE FLOOR SLAB AND CONSTRUCTION METHOD THEREOF
To provide a precast concrete floor slab and its construction method having improved workability at a construction site.SOLUTION: A precast concrete floor slab 10 is provided with a body 1 and engaging parts 2 provided on opposite circumferential surfaces of the body 1. The engaging parts 2 are upper engaging parts 21 each including: an upper surface 11 flush with the upper surface 11 of the body 1; a lower surface 12 flush with the lower surface 12 of the body 1 and having a shorter protruding length from the body 1 than that of the upper surface 11; a first vertical surface extending vertically downward from an end of the upper surface 11; a second vertical surface extending vertically upward from an end of the lower surface 12; and an inclined surface connecting between a lower end of the first vertical surface and an upper end of the second vertical surface. When one of the engaging parts 2 is the upper engaging part 21 on the opposed circumferential surfaces of the body 1, the other engaging part is composed of a lower engaging port 22.SELECTED DRAWING: Figure 1
【課題】現場での作業性を向上したプレキャストコンクリート床版及びその施工方法を提供する。【解決手段】本体１と、前記本体１の対向する周面に設けた係合部２と、を有し、前記係合部２は、前記本体１の上面１１と同一平面となる上面１１と、前記本体１の下面１２と同一平面であり前記本体１からの突出長さが前記上面１１より短い下面１２と、前記上面１１の端部から鉛直下方に延びる第一鉛直面と、前記下面１２の端部から鉛直上方に延びる第二鉛直面と、前記第一鉛直面の下端と前記第二鉛直面の上端を結ぶ傾斜面と、を有する、上係合部２１であり、前記本体１の対向する前記周面において、一方の前記係合部２が前記上係合部２１のとき、他方の前記係合部が前記下係合部２２により構成される、プレキャストコンクリート床版１０。【選択図】図１
