PRECAST CONCRETE MEMBER, FOUNDATION STRUCTURE AND SLAB STRUCTURE
To stably resist to external forces generated at the joints of precast concrete members joined to a slab.SOLUTION: In a precast concrete member 12 in which a part thereof is embedded and joined to a slab 11 and a main body 13 is exposed from the slab 11, a part thereof is formed as a shear key to be fixed to the slab 11, and has a plurality of recesses 140 and 150. Side surfaces 14a and 15a of the shear key are regarded as first side surfaces. The recesses 140 and 150 have a pair of second side surfaces that intersect the first side surface and are continuous along the thickness direction of the shear key and face each other, and a third side surface that intersects the pair of second side surfaces and is located between the pair of second side surfaces and constitutes an inner side surface of the recesses 140 and 150.SELECTED DRAWING: Figure 5
【課題】スラブに接合されるプレキャストコンクリート製部材の接合部位に生じる外力に対し、安定して抵抗できるようにする。【解決手段】スラブ１１に対して一部が埋設されて接合され、本体部１３がスラブ１１から露出するプレキャストコンクリート製部材１２において、一部は、スラブ１１に定着するシアキーとして形成され、かつ、複数の凹部１４０，１５０を備えており、シアキーにおける側面１４ａ，１５ａが第一側面とされ、凹部１４０，１５０は、第一側面と交差するとともにシアキーの厚み方向に沿って連続し、かつ互いに対向する一対の第二側面と、一対の第二側面と交差するとともに一対の第二側面間に位置し、凹部１４０，１５０における奥側面を構成する第三側面と、を有する。【選択図】図５
