WATERTIGHT STRUCTURE AND WATERTIGHT CONSTRUCTION METHOD OF JOINT PORTION IN CONCRETE SECONDARY PRODUCT
PROBLEM TO BE SOLVED: To improve water-tightness of a joint portion in a concrete secondary product without prolonging a construction period and increasing construction cost.SOLUTION: A double packing structure is constituted by a first packing 12 provided on an outer peripheral side of a concrete secondary product 10 and a second packing 14 provided on an inner peripheral side of the concrete secondary product. A joint structure for external water in which a joint filler 16 is coated on an outer peripheral side of the first packing 12 and a joint structure for internal water in which a joint filler 18 is coated on an inner peripheral side of the second packing 14 are applied selectively or in combination.SELECTED DRAWING: Figure 6
【課題】工期および工事費の増大を招来することなくコンクリート二次製品の目地部の水密性を向上させる。【解決手段】コンクリート二次製品１０の外周側に設けられる第１のパッキン１２と、その内周側に設けられる第２のパッキン１４とによって二重パッキン構造を構成し、第１のパッキン１２の外周側に目地材１６を塗布する外水対応目地構造と、第２のパッキン１４の内周側に目地材１８を塗布する内水対応目地構造とを選択的もしくは併用的に適用する。【選択図】図６
