Abstract
The present invention is a manually bendable rebar bolt for use in ground reinforcement, particularly in mining operations. The rebar bolt is a steel rod having a length and a width. The cross-sectional area of the bolt taken along the width generally perpendicular to said length has a long axis and a short axis. The bendable rebar bolt can be manually bent in a direction generally perpendicular to said long axis.
Claims11
A manually bendable rebar bolt for use in ground reinforcement, said rebar cable bolt comprising:
- a steel rod having a length and a width and a cross-sectional area taken along said width generally perpendicular to said length, said cross-sectional area having an oval or elliptical shape including a long axis and a short axis;
- whereby said oval or elliptical shape of said cross-sectional area allows a user to manually bend said steel rod in a direction generally perpendicular to said long axis;
- wherein a ratio of said short axis to said long axis is at least about 0.6 and less than 0.8;
- wherein a length of said long axis is less than or equal to 0.9 inches and a length of said short axis is greater than or equal to 0.6 inches.
A manually bendable rebar bolt for use in ground reinforcement, said rebar cable bolt comprising:
- a rod having a cross-sectional area, said cross-sectional area having an oval or elliptical shape including a long axis and a short axis, said rebar bolt having a width along said long axis and a width along said short axis;
- a ratio of said short axis to said long axis is at least about 0.6 and less than 0.8;
- wherein a length of said long axis is less than or equal to 0.9 inches and a length of said short axis is greater than or equal to 0.6 inches;
- whereby said oval or elliptical shape of said cross-sectional area allows a user to manually bend said rod in a direction generally perpendicular to said long axis.
