EXFOLIATION PREVENTION MATERIAL AND EXFOLIATION PREVENTION STRUCTURE OF CONCRETE STRUCTURE
To provide an exfoliation prevention material and an exfoliation prevention structure of a concrete structure which can be fixed to a concrete surface reliably while being in a simple structure and can be coupled without an end part processing while having a water guidance function.SOLUTION: An exfoliation prevention material 1 comprises a drain sheet 10 having a sheet body 11 and a plurality of water guidance reinforcement rib 12 protruding along a longitudinal direction of a back surface of the sheet body 11, and a lattice member 20 arranged along a front surface of the sheet body 11. The exfoliation prevention structure comprises an exfoliation prevention material 1 having a back surface opposite to a concrete surface of a concrete structure and arranged along the concrete surface, a plurality of fixing members arranged at a front surface of the lattice member 20 and a plurality of anchor material of which tip is arranged in the concrete structure and of which head part protrudes from the concrete surface and is in communication with the exfoliation prevention material 1 and the fixing member, and the exfoliation prevention material 1 is fixed to the concrete surface via bearing pressure of the lattice member 20 by the fixing member.SELECTED DRAWING: Figure 1
【課題】簡易な構造でありながらコンクリート面に確実に固定でき、導水機能を備えながら端部処理を要さずに連結可能なコンクリート構造物の剥落防止材及び剥落防止構造を提供する。【解決手段】剥落防止材１は、シート本体１１と、シート本体１１の背面の長手方向に沿って突設した複数の導水補強リブ１２と、を有する排水シート１０と、シート本体１１の前面に沿って配置した格子材２０と、を備えることを特徴とする。剥落防止構造は、背面をコンクリート構造物のコンクリート面と対向させ、コンクリート面に沿って配置した剥落防止材１と、格子材２０の前面に配置した複数の固定部材と、先端がコンクリート構造物内に配置し、頭部がコンクリート面から突出して剥落防止材１と固定部材を連通した複数のアンカー材と、を備え、固定部材による格子材２０の支圧を介して、剥落防止材１をコンクリート面に固定したことを特徴とする。【選択図】図１
