CRACK CONTROL STRUCTURE OF OPENING USING HARDENED BODY OF FIBER REINFORCED MORTAR

摘要

An anti-cracking structure using an opening of a fiber reinforced mortar hardening ingredient is arranged to make construction is simple, regardless of the crack of one opening of anchorage length control, control critical eigenvalue, it is since the corner of an opening, prevent the fitness for use an of structure from declining by a leak, the elevation design for freely manufacturing a structure not will be installed an individual crack-induced seam. An anti-cracking structure for an opening of control critical eigenvalue around an opening (10) of a concrete structure is formed by installing fiber reinforced mortar hardening ingredient (20), it is smeared by composite fibre and hard in board-like, the inside of a wall is formed in a certain distance from the corner of opening.
