Abstract
A combination construction anchor bolt and retainer for poured concrete installations includes an anchor bolt retaining sleeve which contains an anchor bolt and which is adapted for attachment to a concrete form such that it is imbedded in poured concrete after removal of the form. The sleeve has a single point along its length where its inside diameter matches the bolt outside diameter but the sleeve inside diameter tapers outward from that dimension both above and below that point. This dual tapered design allows the anchor bolt to be adjusted slightly after concrete has been poured and set around the sleeve. The sleeve includes a bolt head retaining pocket and a plurality of wings which prevent it from turning after concrete has set around it.
Claims24
A combination anchor bolt and retainer, comprising:
- a. an anchor bolt with a bolt head and a bolt shaft;
- b. a hollow elongate bolt retaining member which comprises:
- i. an upper portion with an inner dimension sized to accommodate an outer diameter of said bolt shaft, said bolt shaft being somewhat longer than the length of said upper portion such that it extends upward beyond said upper portion when said bolt is received within said retaining member;
- and
- ii. a base portion including a pocket sized and shaped to receive and retain said bolt head and to prevent said bolt head from being turned within said pocket, said base portion having a detent extending into said pocket below and across a portion of said bolt head to prevent said bolt head from dropping downwardly out of said pocket.
A combination anchor bolt and retainer, comprising:
- a. an anchor bolt with a bolt head and a bolt shaft;
- b. a hollow elongate bolt retaining member which comprises:
- i. an upper portion with an inner dimension which tapers inward from the bottom up to a point of narrowest dimension and then tapers outward from that point to a top of the upper portion, said point of narrowest dimension being slightly larger than the outer diameter of said bolt shaft, said bolt shaft being somewhat longer than the length of said upper portion such that it extends upward beyond said upper portion when said bolt is received within said retaining member;
- and
- ii. a base portion including a pocket sized and shaped to receive and retain said bolt head and to prevent said bolt head from being turned within said pocket.
A combination anchor bolt and retainer, comprising:
- a. an anchor bolt with a bolt head and a bolt shaft;
- b. a hollow elongate bolt retaining member which comprises:
- i. an upper portion with an inner dimension sized to accommodate an outer diameter of said bolt shaft, said bolt shaft being somewhat longer than the length of said upper portion such that it extends upward beyond said upper portion when said bolt is received within said retaining member;
- ii. a base portion including a pocket sized and shaped to receive and retain said bolt head and to prevent said bolt head from being turned within said pocket;
- and
- iii. at least one wing extending outward from either said upper portion or said base portion.
A combination anchor bolt and retainer, comprising:
- a. an anchor bolt with a bolt head and a bolt shaft;
- and
- b. a hollow elongate bolt retaining member which comprises:
- i. a tubular portion with an inner dimension sized to accommodate an outer diameter of said bolt shaft, said bolt shaft being somewhat longer than the length of said tubular portion such that it extends beyond said tubular portion when said bolt is received within said retaining member;
- and
- ii. a head retaining portion including a pocket, said pocket being sized and shaped to receive and retain said bolt head and to prevent said bolt head from being turned within said pocket, said pocket having a first opening in communication with said tubular portion and a second opening opposite said first opening, said head retaining portion also including a detent extending into said pocket between said bolt head and said second opening and across a portion of said bolt head to prevent said bolt head from slipping out of said pocket through said second opening.
