PRECAST CONCRETE FOUNDATION BEAM STRUCTURE
To provide a foundation beam structure which facilitates carry-in to a site and facilitates joining to a pile head part and completion of a beam at the site in a precast concrete foundation beam.SOLUTION: There is provided a foundation beam structure 1 in which a foundation beam 5 and a pile head part foundation 8 are joined to each other, wherein a pair of precast concrete beam members 10 and 10 where a beam main reinforcement 14 projects in a long-axis direction of the foundation beam 5, and a part of a first stirrup reinforcement 15 projects in a beam width direction of the foundation beam 5 so as to surround the beam main reinforcement 14 are made to face each other so as to form a first joint space S1 in the beam width direction and are mounted on a bottom plate, a second stirrup reinforcement 21 is arranged so as to surround a pair of beam main reinforcements 15 in a second joint space S2 between the pair of precast concrete beam members 10 and 10 and the pile head part foundation 8, cast-in-place concrete is placed in the first joint space S1 and the second joint space S2, and the whole is integrated.SELECTED DRAWING: Figure 1
【課題】 プレキャストコンクリート基礎梁において、現場への搬入が容易で、現場での杭頭部への接合や梁完成も容易に行える基礎梁構造を提供することにある。【解決手段】 基礎梁５と杭頭部基礎８とが接合された基礎梁構造１であって、基礎梁５の長軸方向に梁主筋１４が突出し、梁主筋１４を囲むように基礎梁５の梁幅方向に第１のスターラップ筋１５の一部が突出した１対のプレキャストコンクリート梁部材１０、１０を、梁幅方向に第１の接合空間Ｓ１を形成するように対向させて、底盤上に載置し、１対のプレキャストコンクリート梁部材１０，１０と杭頭部基礎８との間の第２の接合空間Ｓ２に１対の梁主筋１５を囲むように第２のスターラップ筋２１が配筋され、第１の接合空間Ｓ１および第２の接合空間Ｓ２に現場コンクリートが打設され、全体が一体化されている。【選択図】 図１
