Abstract
Abstract A material for fixing an anchor bolt or the like, which is used, in case of inserting and planting an anchor bolt in a planting hole bored in a concrete foundation or base rock, for filling the gap between the planting hole and the anchor bolt to couple the both, in which paste-like base material and hardener for cold-setting resin requiring hardener are filled separately in long glass tubes together with artificial solid ball-like aggregates, and a plurality of pairs of them are arranged in a hollow tubular structure and adhered mutually with adhesive, and a method of manufacturing the same.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A material for fixing an anchor bolt or the like, comprising a plurality of pairs of first and second members having crushable tube envelopes formed of a frangible material, respectively, and being arranged along a cylindrical surface to form a tubular structure having a central cavity, the envelope of said first member being filled with artificial solid ball-like aggregates and paste-like base material of cold-setting resin requiring hardener, the envelope of said second member being filled with artificial solid ball-like aggregates and paste-like hardener for said resin, said first and second members being adhered mutually with adhesive, and the outer diameters of said members being selected to adapt the outer diameter of said tubular structure for a predetermined planting hole.
Claim 2
Dependent Claim
120 words
A material for fixing an anchor bolt or the like, comprising a plurality of pairs of first and second members having crushable tube envelopes formed of a frangible material, respectively, and being arranged along a cylindrical surface to form a tubular structure having a central cavity, the envelope of said first member being filled with artificial solid ball-like aggregates and paste-like base material of cold-setting resin requiring hardener, the envelope of said second member being filled with artificial solid ball-like aggregates and paste-like hardener for said resin, said first and second members being adhered mutually with adhesive, and the outer diameters of said members being selected to adapt the outer diameter of said tubular structure for a predetermined planting hole.
Claim 3
Dependent Claim
41 words
A material according to claim 1, characterized in that said central cavity of said tubular structure is filled with artificial solid ball-like aggregates and the particles of said aggregates are adhered mutually and with said first and second members with adhesive.
Claim 4
Dependent Claim
18 words
A material according to claim 1 or 2, characterized in that said tube envelopes are hard plastic tubes.
Claim 5
Dependent Claim
19 words
