Abstract

Abstract An anchoring member is inserted into an anchoring hole in a support structure and has transverse dimensions smaller than those of the anchoring hole, and is supported with clearance in such anchoring hole by means of a cap member of ring-shaped configuration which surrounds the anchoring member at the trailing end thereof and closes the open end of the clearance. The anchoring member is of a tubular configuration and is closed at its leading end, an aperture communicating the interior of the anchoring member with the clearance. A body of hardenable material is introduced into the clearance through the aperture and by means of a shielding arrangement accommodated in the interior of the tubular anchoring member and communicating with the aperture. At least a portion of the ring-shaped cap member is at least translucent so that the introduction of the hardenable material into the clearance can be monitored therethrough. A depression, preferably an annular groove, is visible through the translucent portion and has such dimensions that, due to its viscosity, the hardenable material will not be able to penetrate into the depression until after the pressure in the clearance has exceeded a value indicative of the completion of the clearance-filling process. A small-sized opening communicates the clearance with the exterior of the cap member and allows air to escape from the clearance during the clearance-filling operation, while preventing the hardenable material from escaping therethrough until the pressure of the hardenable material has reached a predetermined level.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 160 words
An arrangement for securing an object to a support structure having an anchoring hole, comprising an anchoring element having one part of transverse dimensions smaller than, and another part of transverse dimensions substantially corresponding to those of the anchoring hole, said anchoring element being insertable into the anchoring hole through an open end thereof so that said other part supports said anchoring element at the open end of the anchoring hole with clearance between the latter and said one part and closes the open end of said clearance upon insertion; means for introducing a body of hardenable material into said clearance for hardening therein about said one part of said anchoring element to thereby anchor the latter in the anchoring hole; and means for monitoring the degree of filling of said clearance by the hardenable material, including at least a translucent portion of said other part of said anchoring element through which said clearance and said body can be observed.
Claim 2
Dependent Claim 160 words
An arrangement for securing an object to a support structure having an anchoring hole, comprising an anchoring element having one part of transverse dimensions smaller than, and another part of transverse dimensions substantially corresponding to those of the anchoring hole, said anchoring element being insertable into the anchoring hole through an open end thereof so that said other part supports said anchoring element at the open end of the anchoring hole with clearance between the latter and said one part and closes the open end of said clearance upon insertion; means for introducing a body of hardenable material into said clearance for hardening therein about said one part of said anchoring element to thereby anchor the latter in the anchoring hole; and means for monitoring the degree of filling of said clearance by the hardenable material, including at least a translucent portion of said other part of said anchoring element through which said clearance and said body can be observed.
Claim 3
Dependent Claim 12 words
An arrangement as defined in claim 1, wherein said portion is transparent.
Claim 4
Dependent Claim 57 words
An arrangement as defined in claim 1, wherein said other part of said anchoring element has a depression of such dimensions that the hardenable material can penetrate thereinto only when the pressure in said clearance reaches a predetermined level; and wherein said portion of said other part of said anchoring member at least partly bounds said depression.
Claim 5
Dependent Claim 28 words
An arrangement as defined in claim 3, wherein said depression is configurated as an annular groove in said other part around said one part of said anchoring element.
Claim 6
Dependent Claim 87 words
An arrangement as defined in claim 1, wherein said other part of said anchoring element has at least one opening for escape of air from said clearance during the introduction of said body of hardenable material into said clearance; and wherein said opening is so dimensioned that the hardenable material can escape from said clearance through said opening and appear at the exterior of said other part of said anchoring element only after the pressure of the hardenable material in said clearance has reached a predetermined level.
Claim 7
Dependent Claim 36 words
An arrangement as defined in claim 1, wherein said one part is constituted by an anchoring member, and said other part by a ring-shaped cap member surrounding a portion of said anchoring member upon assembly therewith.
Claim 8
Dependent Claim 19 words
An arrangement as defined in claim 6, wherein said cap member is entirely of an at least translucent material.
Claim 9
Dependent Claim 70 words
An arrangement as defined in claim 6, wherein said anchoring member is generally tubular and has a closed leading, and an open trailing end as viewed in the direction of introduction of said anchoring element into the anchoring hole; and wherein said introducing means includes at least one aperture in said anchoring member for passage of the hardenable material therethrough from the interior of said anchoring member into said clearance.
Claim 10
Dependent Claim 53 words
An arrangement as defined in claim 8, wherein said introducing means further includes shielding means insertable into the interior of said anchoring member through said open trailing end thereof to communicate with said aperture and operative for preventing the hardenable material from filling the interior of said anchoring member around said shielding means.
Claim 11
Dependent Claim 36 words
An arrangement as defined in claim 9, wherein said anchoring member has an internal thread at said trailing end thereof; and wherein said shielding means prevents the hardenable material from penetrating toward and into said thread.
