CAPSULE FOR FIXING ANCHOR BOLT WITH REDUCED DRIVING RESISTANCE

PROBLEM TO BE SOLVED: To alternately charge a curing resin component and a curing agent component in a cylindrical glass container provided with a specified number or more of constricted recesses so that separated layers formed by the curing reaction coincide with the constricted recesses and further, the constricted recesses are more than a specified number. SOLUTION: This container 2 is a cylindrical glass tube from which strains are removed. Three U-shaped constricted recesses 3 are formed in the tube. A curing resin component 5 and a curing agent component 6 are alternately charged so that separated layers 4 coincide with the constricted recesses 3. Thereafter, aggregate 7 is charged to the uppermost layer and the opening is molten and sealed to form a fixing capsule 1 for an anchor bolt. The weight ratio in one layer of the curing resin component and the curing agent component is decided to be 3:1. The number of the constricted recesses is two or more and the constricted depth of the recesses is set so that the contact area of the curing resin component and the curing agent component is equivalent to 15-65 % of a case that the constricted recesses are not formed. In this way, the driving resistance is reduced and a favorable fixing strength having less scattering can be obtained.
