CONNECTION STRUCTURE OF PRECAST CONCRETE MEMBERS
To provide means for maintaining an arrangement interval of shear reinforcing bars in a connecting structure of precast concrete members and making the precast concrete members as small as possible.SOLUTION: There is provided a connection structure of precast concrete members in which a main bar 30 and a shear reinforcing bar 50 are arranged inside, which includes at least a sleeve 70 provided on one precast concrete member 10, a filler 80 filling the sleeve 70, and an insertion portion 40 in which a main bar 30 of the other precast concrete member 20 is exposed and inserted into the sleeve 70. By arranging the shear reinforcing bar 50 not on the sleeve but so as to maintain a basic spacing L of an approximately the same length between the precast concrete members to be connected, a cover thickness of each precast concrete member is calculated based on the position of the sleeve or shear reinforcing bar as a standard, so that an overall size of the precast concrete member is reduced.SELECTED DRAWING: Figure 2
【課題】プレキャストコンクリート部材の連結構造にあって、せん断補強筋の配置間隔を維持し、かつプレキャストコンクリート部材もできる限り小さな寸法にする手段を提供すること。【解決手段】内部に主筋３０及びせん断補強筋５０を配置したプレキャストコンクリート部材の連結構造であって、一方のプレキャストコンクリート部材１０に設けたスリーブ７０と、スリーブ７０内に充填する充填材８０と、他方のプレキャストコンクリート部材２０の主筋３０が露出して前記スリーブ７０へと挿入する挿入部４０と、を少なくとも有し、前記せん断補強筋５０をスリーブ上に配置せずに、連結するプレキャストコンクリート部材間で略等長の基本間隔Ｌを維持するように配置することで、各プレキャストコンクリート部材のかぶり厚の計算をスリーブまたはせん断補強筋の位置を基準とプレキャストコンクリート部材の全体寸法のサイズダウンを図る。【選択図】図２
