Grid mesh anchor
The present invention concerns an anchor assembly for providing a secure point of attachment at a grid mesh platform. The anchor assembly comprises a housing in the form of an elongated case with a central hollow channel, generally rectangular in shape with a flat base and roof. The base includes openings in the form of access slots to provide access from the channel to the exterior of the base. The anchor assembly also comprises a suspension member located within the channel. In operation the anchor assembly spans adjacent structural members underlying the mesh grid. A coupling member in the form of a sling having an end loop is engaged by the suspension member which passes through the end loop of the sling. The sling also passes through one of the slots in the base of the elongated case. An opposite end of the sling provides an anchor point.
1. A grid mesh anchor assembly comprising:
an elongate housing including a base;
a suspension member located entirely within the elongate housing;
at least one opening provided in the base of the elongate housing;
a flexible coupling member passing through the opening and engaging the suspension member for suspension of the flexible coupling member from the suspension member, the flexible coupling member capable of passing through a grid mesh supported by at least two adjacent structural members underlying the grid mesh;
a pair of feet located at respective opposing ends of the base of the elongate housing and capable of locating on an upper side of the grid mesh, the suspension member located above the pair of feet so that load imparted on the suspension member via the flexible coupling member is transferred to the pair of feet and the upper side of the grid mesh; and
the elongate housing is in the form of a substantially enclosed case comprising the base and a roof configured to enclose the suspension member, and the roof is openable for access to an interior of the substantially enclosed case.
2. A grid mesh anchor assembly as claimed in claim 1 wherein a location of the grid mesh anchor assembly ensures the suspension member is capable of spanning said at least two adjacent structural members.
3. A grid mesh anchor assembly as claimed in claim 2 wherein the pair of feet are capable of resting upon the grid mesh above the underlying structural members to transfer forces from the suspension member to said structural members via the pair of feet.
4. A grid mesh anchor assembly as claimed in claim 1 wherein the substantially enclosed case also comprises a pair of each of side and end walls that taper from the roof downward and outward toward the base.
5. A grid mesh anchor assembly as claimed in claim 1 wherein the opening in the base is in the form of an access slot in the base.
6. A grid mesh anchor assembly as claimed in claim 1 wherein the suspension member is in the form of an elongated rod or tube.
7. A grid mesh anchor assembly as claimed in claim 6 wherein the rod or tube occupies substantially a full length of the elongate housing.
8. A grid mesh anchor assembly as claimed in claim 1 also comprising a plurality of straps for releasably securing the suspension member within the elongate housing.
9. A grid mesh anchor assembly as claimed in claim 1 wherein the elongate housing comprises one or more securement points capable of securing said grid mesh anchor assembly to an associated structure from which the flexible coupling member is capable of being suspended.
10. A grid mesh anchor assembly as claimed in claim 1 wherein the flexible coupling member is in the form of a sling through which the suspension member passes for engagement.
11. A grid mesh anchor assembly as claimed in claim 1 wherein the flexible coupling member is in the form of a flexible rope, wire or cable.
12. A grid mesh anchor assembly as claimed in claim 1 wherein the flexible coupling member is capable of attaching to a safety fall device.
13. A grid mesh anchor assembly as claimed in claim 12 wherein said grid mesh anchor assembly is rated to 22.2 kN (5000 lbs) as a personal fall arrest anchorage.
14. A grid mesh anchor assembly as claimed in claim 1 wherein the flexible coupling member is capable of attaching to a lifting device.
