摘要： An industrial mat that includes a core construction that provides strength and rigidity to the mat, with the core construction including various layers or plies of components at least some of which are typically made of wood or engineered wood; and a durable skin that surrounds and encapsulates at least the wood components of the mat or the entire core construction. The skin has a thickness sufficient to provide environmental resistance to the wood components or to the core construction to which it is applied. The skin also provides abrasion resistance to the boards and mat.

摘要： An industrial mat having a supporting structure; an upper layer provided above the supporting structure for forming an upper surface of the mat, a lower layer provided below the supporting structure for providing a lower surface of the mat; and lifting elements attached to the upper layer, the lower layer or the supporting structure. The lifting elements include D-shaped members, O-shaped members, U-shaped members, eyelets, hooks, circular or polygonal rings, chains, or cables that are configured and dimensioned for attachment to attached to the supporting structure or the upper or lower layer with sufficient strength to provide certified overhead lifting of the mat for installation and reclamation thereof.

摘要： A method and apparatus for the construction of a flooring system for use at a construction site such as an oil well drilling site. The flooring system is formed by interlocking a plurality of flooring units. Each of the flooring units includes a rectangular base section and a surface section attached to and overlaying the base section. One end of the rectangular base section is aligned with one end of the surface section which has at least one open-ended locking slot along its length. Located on the opposing end of the surface section is at least one locking tab formed from the surface section and projecting beyond and above the edge of the base section. The locking tab is aligned with the locking slot of the flooring unit. The method of constructing a flooring system utilizing such units includes positioning one unit, with the use of a lifting device such as a crane, adjacent to a second flooring unit and inserting the locking tab of the first unit into the adjacent second unit. By interlocking a plurality of such units, a flooring system is fabricated at a construction site which is strong enough to support heavy equipment, yet easily installed and removed.
摘要翻译：一种在诸如油井钻井现场的施工现场使用的地板系统的构造方法和装置。地板系统通过联锁多个地板单元而形成。每个地板单元包括矩形基部和附接到基部并覆盖基部的表面部分。矩形基部的一端与表面部分的一端对准，该端部沿着其长度具有至少一个开口的锁定槽。位于表面部分的相对端上的是至少一个从表面部分形成并且突出到基部的边缘之上和之上的锁定突片。锁定片与地板单元的锁定槽对齐。利用这种单元构造地板系统的方法包括使用与第二地板单元相邻的诸如起重机的提升装置来定位一个单元，并将第一单元的锁定片插入到相邻的第二单元中。通过联锁多个这样的单元，在建筑工地上制造地板系统，其强度足以支撑重型设备，但容易安装和拆除。
