Abstract
An end cap assembly for interlocking with an oil field mat usable to support trucks, equipment and personnel around a drilling rig. The end cap assembly having an elongated base layer, a base layer coupler, a top layer, a middle layer, a plurality of holes, a plurality of fasteners and a plurality of coupler fasteners. Each coupler fastener can be disposed through the holes in the board of the end cap assembly to form a base layer coupler to create a tri-layer oil field mat.
Claims26
An end cap assembly for interlocking with an oil field mat, comprising
- (a) an elongated base layer with a top side and a bottom side, and a base layer coupler fastened to the top side on an end, the elongated base layer comprising a plurality of base layer boards, the plurality of base layer boards having a longitudinal axis in a first direction, wherein the based layer coupler comprises:
- (i) corner locking boards, wherein the corner locking boards are flush with a side edge of the elongated base layer and positioned at each corner of the side edge, the corner locking boards mounted across at least one of the base layer boards;
- (ii) a pair of interior long locking boards positioned an interior long locking board width away from the side edge and between the corner locking boards;
- and
- (iii) an exterior locking board between the pair of interior long locking boards, the exterior locking board flush with the side edge, and interior locking boards and exterior locking board configured in a staggered pattern, each locking board mounted across a plurality of base layer boards;
- (b) a top layer comprising a plurality of top layer boards, each top layer board having a longitudinal axis in the first direction;
- and
- (c) a middle layer comprising a plurality of middle boards, each middle board having a longitudinal axis in a second direction that is 90 degrees from the first direction, with the middle layer disposed between the elongated base layer and the top layer;
- (d) a plurality of holes formed through each board of each layer, wherein the top layer holes align with the middle layer holes and with the base layer holes;
- (e) a plurality of multilayer fasteners, each multilayer fastener disposed in aligned holes of the top, middle and base layers;
- and
- (f) a plurality of coupler fasteners, each coupler fastener disposed through holes in boards used to form the base layer coupler.
