Abstract:
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat, with the layers protecting the support core. Bumpers are provided upon the longitudinal sides of the core, the front and rear end sides of the core, or upon all sides to protect the core from damage due to transport or installation of the mat. The bumpers are typically made of wood, or of a plastic or elastomeric material and have a shape that absorbs impact and shock forces. The mat also includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core, with the lifting elements configured and dimensioned to provide certified overhead lifting of the mat for installation and reclamation thereof.
Abstract:
A mat that includes first and second side beams, a core structure located between and connected to the side beams, with the support structure including longitudinal members and having a height that is less than that of the side beams, a plurality of joining rods that attach the side beams to the support structure, with the joining rods passing through the sides of the side beams and the sides of the longitudinal members of the support structure; one or more elongated members attached to the upper portion of the support structure to form with the beams the top surface of the mat, and one or more elongated members attached to the lower portion of the support structure to form with the beams the bottom surface of the mat. If desired, steel plates can be provided between the beams and longitudinal members to increase the strength and ruggedness of the mat.
Abstract:
A building unit system includes discrete, irregular, non-geometric units, including first units and second units having a different size and shape than the first units. The first units and second units mate with one another to form a continuous surface without overlap between units or large gaps between units, resulting in a natural, custom fitted appearance such that a regular geometric pattern is not readily apparent.
Abstract:
An access mat is described having a rectangular body with a length dimension and a width dimension. The body includes three laminated layers of lumber, with each of the lumber having a longitudinal axis. A first layer of the three layers has a plurality of lumber, with the longitudinal axis of each lumber in a parallel orientation extending across the length dimension. A second layer of the three layers has a plurality of lumber with the longitudinal axis of each lumber in a parallel orientation extending across the width dimension. A third layer of the three layers has a plurality of lumber with the longitudinal axis of each lumber in an angular orientation relative to the longitudinal axis of the plurality of lumber of the second layer. Correctors are provided for connecting the body with other like bodies.
Abstract:
Generally L-shaped, square, rectangular, triangular, hexagonal, parallelogram and other-shaped paving stones with inter-fitting vertical spacers forming serpentine side contact surfaces that provide enhanced stone-to-stone interlocking in both water-permeable and water-impermeable paving installations.
Abstract:
A slat for use in a roll-out sheet of construction material is provided. The slat has an elongated body extending longitudinally. A projection is disposed at a first lateral end of the body. A socket is disposed at a second lateral end of the body, opposite to the first lateral end. The projection and the socket are structurally complementary to each other. A wedge is formed with the projection as a self-tightening mechanism. A roll-out structure is also provided. The roll-out structure has at least two adjacent slats which are structurally the same. The projection of one of the slats is insertable into the socket of the other slat to connect them, and the projection is rotatable in the socket. The rotation of the projection in the socket allows the wedge to engage the socket, to lock the slats with each other.
Abstract:
A method making an oil field mat from a plurality of synthetic board to create a tri-layer oil field mat usable to support trucks, equipment, and personnel around a derrick, or a Christmas tree having central couplers and end caps.
Abstract:
Method of sealing the gap between adjacent mats in a reusable load-supporting surface includes placing an elongated closed-cell compressible sponge rubber seal member along the edge of the first side of a first mat. The third side of a second mat is positioned adjacent to the first side of the first mat, wherein the main body of the seal member is sandwiched between the respective aligned edges of the adjacent mats. At least one locking pin hole of the second mat is aligned over a locking pin hole of the first mat and a locking pin is secured therein.
Abstract:
A synthetic grass tile system and method are disclosed. An artificial turf tile system has a plurality of connectable tile members and a synthetic turf arrangement adhered to the tile members. The interconnected tile members, having the turf attached thereto, are cut into sections. The sections are then secured on a pallet for sale at a retail establishment. A method for producing a modular synthetic grass tile system follows the following steps: (a) providing a plurality of tile members; (b) snapping the tile members together at their edges to form a grid; and (c) adhering a sheet of synthetic turf to the top surface of the tile members.
Abstract:
Apparatus for sealing the gap between adjacent interconnecting mats in a reusable load-supporting surface deployed on the ground includes a seal member. The seal member includes an elongated main body and an elongated planar tail extending outwardly therefrom. The main body is positionable in the gap and the tail is configured to extend into at least a portion of the interface formed between upper and lower lips of the adjacent mats.
