Abstract
An anchorage kit 100 includes components which may be assembled in various ways to provide anchorages 101-107 suitable for connection in series between a safety line and any of various structural members. The kit 100 includes opposing brackets 120, 140 which are interconnected by bolts 170 extending therebetween, and which may be supplemented by one or more braces 160 secured to the intermediate portion of one or more of the bolts 170.
Claims23
An anchorage kit having components which may be combined in various manners to secure a safety line to various types of support structures, comprising:
- a first bracket and a second bracket, wherein said first bracket and said second bracket may be aligned so that a first opening in said first bracket aligns with a first opening in said second bracket, and a second opening in said first bracket aligns with a second opening in said second bracket, and wherein a third opening is formed in at least one of said first bracket and said second bracket to anchor the safety line;
- a first brace and a second brace, wherein at least one opening extends through each said brace;
- a first bolt and a second bolt, wherein said first bolt is sized and configured to insert through each said first opening and through said at least one opening in said first brace, and said second bolt is sized and configured to insert through each said second opening and through said at least one opening in said second brace;
- and
- at least four threaded nuts sized and configured to thread onto said bolts, wherein each said bolt may be secured at each end relative to a respective bracket, and each said brace may be secured at an intermediate point along a respective bolt.
An anchorage assembly interconnected in series between a safety line and a structural member, comprising:
- a first bracket having a first bearing surface which is flat and faces in a first direction, and a second bearing surface which is concave and faces in a second, opposite direction;
- a second bracket having at least one of a bearing surface which is flat and a bearing surface which is concave, wherein an opening extends through at least one of said first bracket and said second bracket to anchor the safety line;
- at least two bolts interconnected between said first bracket and said second bracket, wherein said bolts extend perpendicular to said first bearing surface on said first bracket;
- and
- an L-shaped brace defining a hole sized to receive one of said bolts, wherein said brace has a relatively longer segment which extends parallel to said first bearing surface on said first bracket, and a relatively shorter segment which extends perpendicular to said relatively longer segment, and a flange on the structural member is clamped between said relatively longer segment and one of said first bracket and said second bracket.
An anchorage assembly interconnected in series between a safety line and a structural member having at least one flange which terminates in a distal end, comprising:
- a first bracket having at least one bearing surface;
- a second bracket having at least one bearing surface, wherein at least one of said first bracket and said second bracket is configured to anchor the safety line;
- a brace sized and configured to bear against the at least one flange proximate the distal end, wherein said brace is disposed between said first bracket and said second bracket;
- and
- at least two bolts interconnected between said first bracket and said second bracket, wherein said bolts extend perpendicular to said at least one bearing surface on each said bracket, and at least one of said bolts extends through a hole in said brace, and said brace is clamped to said flange by at least one nut threaded onto said at least one of said bolts.
An anchorage assembly interconnected in series between a safety line and a structural member, comprising:
- a first bracket having a first bearing surface which is flat and faces in a first direction, and a second bearing surface which is concave and faces in a second, opposite direction;
- a second bracket having at least one of a bearing surface which is flat and a bearing surface which is concave, wherein an opening extends through at least one of said first bracket and said second bracket to anchor the safety line;
- at least two bolts interconnected between said first bracket and said second bracket, wherein said bolts extend perpendicular to said first bearing surface on said first bracket;
- and
- two L-shaped braces, each of said braces defining a hole sized to receive one of said bolts, and each of said braces having a relatively longer segment which extends parallel to said first bearing surface on said first bracket, and a relatively shorter segment which extends perpendicularly away from said first bearing surface on said first bracket.
An anchorage assembly interconnected in series between a safety line and a structural member, comprising:
- a first bracket having a U-shaped cross section defined by a base plate and opposite side plates, wherein said base plate defines a flat bearing surface that faces away from said side plates, and said side plates have distal edges which face away from said base plate and define a concave bearing surface;
- a second bracket having at least one of a bearing surface which is flat and a bearing surface which is concave, wherein an opening extends through at least one of said first bracket and said second bracket to anchor the safety line;
- and
- at least two bolts interconnected between said first bracket and said second bracket, wherein said bolts extend perpendicular to said base plate.
