Anchors and methods for anchoring an underground storage tank
Various anchors and methods for anchoring an underground storage tank are provided. The anchor includes a base and at least one retention mechanism connected to the base for retaining various configurations of hooks and straps for holding the tank. The retention mechanism includes an opening and a retention member that is configured to open or close the opening by displacing or collapsing said retention member. The anchor may include a composite base having a footing and a spine extending upwardly from the footing so as to define footing portions on either side of the spine. The footing and the spine may have a composite composition that includes a matrix material and a reinforcement structure embedded within the matrix material. The retention mechanism may be connected to the spine of the composite base for retaining a hook for anchoring the underground storage tank.
1. An anchor for anchoring an underground storage tank via a hook-and-strap assembly, the anchor comprising:
a base;
a retention mechanism connected to the base, the retention mechanism comprising:
an opening in the base;
a first chamber and a second chamber extending from the opening in generally opposed relation to each other;
a retention member comprising a first end and a second end respectively insertable into the first chamber and the second chamber, the retention member being sized and configured to be displaceable between:
an open position where the first end of the retention member is located within the opening and is insertable through a hook of the hook-and-strap assembly for anchoring the underground storage tank; and
a closed position where the first end is located within the first chamber and the second end is located in the second chamber, thereby retaining the hook with respect to the retention member; and
a locking mechanism for locking the retention mechanism with respect to the base in the closed position.
2. The anchor of claim 1 , wherein the retention member is a retention bar, has a one-piece structure and is straight.
3. The anchor of claim 2 , wherein the retention bar and the first and second chambers are oriented lengthwise along the base, the base being positionable in generally parallel relation with respect to a longitudinal axis of the underground tank.
4. The anchor of claim 1 , wherein the locking mechanism comprises a pin-and-hole locking system.
5. The anchor of claim 4 , wherein the locking mechanism comprises:
a hole provided through the base and communicating with one of the chambers;
a recess provided in the retention mechanism, the recess being located so as to align with the hole in the closed position; and
a pin insertable through the hole and into the recess so as to secure the retention mechanism with respect to the base in the closed position.
6. The anchor of claim 5 , wherein the hole and the pin are oriented in transverse relation with respect to the retention member.
7. The anchor of claim 6 , wherein the locking mechanism comprises a first locking system for locking the first end of the retention member within the first chamber and/or a second locking system for locking the second end of the retention member within the second chamber.
8. The anchor of claim 1 , further comprising multiple retention members arranged along the base.
9. The anchor of claim 1 , wherein the first chamber and the second chamber each have a closed end.
10. The anchor of claim 9 , wherein the retention member, the first chamber and the second chamber are sized and configured such that the first end of the retention member abuts on the closed end of the first chamber in the closed position.
11. The anchor of claim 9 , wherein the retention member, the first chamber and the second chamber are sized and configured such that the second end of the retention member abuts on the closed end of the second chamber in the open position.
12. The anchor of claim 1 , comprising multiple openings provided along the base wherein two adjacent openings have a common chamber which extends from one opening to the adjacent opening and through the base, such that the retention member can slide along the common chamber to close at least one of the two adjacent openings; wherein the chambers of the multiple openings communicate with one another so as to form a collinear tunnel; and wherein the first chamber extending from the opening located at an edge of the anchor has an open end which can slidably receive one or more retention members inserted through the open end.
13. The anchor of claim 1 , wherein the retention mechanism is embedded within the base.
