Title:
REINFORCEMENT RUST PREVENTION FORM SPACER
Document Type and Number:
Japanese Patent JP2017048454
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a reinforcement rust prevention form spacer material with securing of set covering thickness and containing a metal (zinc or a zinc alloy) having an ionization tendency higher than that of iron as an anode, for the purpose of the elongation of the service life of a reinforced concrete structure.SOLUTION: An anode material body is obtained by coating and molding a catalyst-worked zinc anode 1 and an electrically connected metallic bolt 2 with porous mortar 3 having many gaps. The anode material body and a female screw part provided at a bent connection metal fitting 4 capable of being fitted to a reinforcement are screwed with the metallic bolt exposed from the anode material body and whose tip has been subjected to peak shaping, and the reinforcement is pinched and fasten therebetween to secure firm fixing and electrical conduction, thus effective covering thickness can be obtained. In a state where corrosion current is generated in the reinforcement of the structure body, electrochemical rust prevention effect can be also obtained.SELECTED DRAWING: Figure 1
