PRECAST MEMBER JUNCTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a junction structure capable of further adequately and easily connecting precast members constituting a concrete structure.SOLUTION: A junction structure comprises: a shear key 1 formed on a joint surface Pa of a precast member P' as one of members to be connected; and a recess 2 formed on a joint surface Pa of a precast member P'' as the other one of the members to be connected, into which the shear key 1 is stored. The shear key 1 is a cylindrical body 1a filled with a fiber-reinforced concrete 6 and comprises one side 1c, which is buried in the precast member P' and the other side 1d of the cylindrical body 1a across a virtual first flat surface x including a central axis 1b of the cylindrical body 1a or a virtual second flat surface y parallel to the virtual first flat surface x. The recess 2 has a shape fitting to an outer shape of the shear key 1 and a depth L1 allowing a part of the shear key 1 to be stored.SELECTED DRAWING: Figure 3
【課題】コンクリート構造物を構成するプレキャスト部材同士を、より適切且つ容易に接合し得る接合構造を提供する。【解決手段】接合対象となる一方のプレキャスト部材Ｐ’の接合面Ｐａに形成されるせん断キー１と、接合対象となる他方のプレキャスト部材Ｐ”の接合面Ｐａに形成されると共に前記せん断キー１を納める凹所２とからなる。前記せん断キー１は、繊維強化コンクリート６を充填させた円筒体１ａであって、この円筒体１ａの中心軸１ｂを含む仮想の第一平面ｘ又はこの仮想の第一平面ｘに平行な仮想の第二平面ｙを挟んだ一方側１ｃを前記一方のプレキャスト部材Ｐ’内に埋設させた円筒体１ａの他方側１ｄによって構成されており、前記凹所２は、前記せん断キー１の外形に整合する形状を有すると共に、前記せん断キー１の一部を納める深さＬ１となっている。【選択図】図３
