Mat overlaps (3) and mat underlaps (4) are provided with holes (6) on interconnecting mats through interconnecting mats (2), and connectors for interconnecting mats (1) are integrated in mat overlaps (3) or mat underlaps (4), thus being always available for connecting interconnecting mats (2). Mat overlaps (3) and mat underlaps (4) on interconnecting mats (2) are provided with recesses for the plates (5). Connectors (1) for interconnecting mats are integrated into interconnecting mats during production to prevent losing connectors for interconnecting mat and expedite connection of interconnecting mats. Connector for interconnecting mat is limited with at least one securing plate (7) on one side of the connecter head (15).

An inventory of industrial mats (100) having different core or internal constructions (115) that are not visible because of the inclusion of side, end, upper and lower components (105, 110) which hide the core or internal construction from view, wherein each mat (100) has an electronic device that indicates what is present in the hidden core or internal construction of the mat, with the electronic device including a processor, storage, and wireless communications circuitry that is configured to transmit identification, location, usage or physical property information of the mats over a wireless telecommunications network. Also, a method for providing an identification of mat properties or usage for an inventory of mats by viewing the information stored on the electronic device or by retrieving over a wireless telecommunications network identification, location, usage or physical property information of the mats from the storage of the electronic device.

A mat that includes first and second side beams (210, 240), a core support structure located between and connected to the side beams, with the support structure including longitudinal members (225A, 225B, 225C), a plurality of joining rods (260) 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 (250A, 250B, 250C) attached to the support structure to form with the top working surface of the mat, and/or one or more elongated members (255A, 255B, 255C) attached to the support structure to form the bottom working surface of the mat. If desired, steel plates (205A, 205B, 205C, 205D) can be provided between the beams and longitudinal members to increase the strength and ruggedness of the mat. The mat also includes various lifting elements (170) including D-, O- or U-shaped members, eyelets, hooks, rings, chains, or cables.

The object of the invention is a load bearing structure, which comprises a surface plate (1), a first and a second side wall (2), a first and a second end wall (3) and a base plate (4), which elements are fastened to each other to form an essentially enclosed hollow structure, inside which is a support structure assembled from support elements (5, 6), the support structure receiving a compressive load. The support elements (5) are profiled battens, which are disposed in the structure longitudinally at a distance from each other, and the support elements (6) are profiled battens, which are disposed in the structure transversely at a distance from each other.

A problem with unpaved roads is that can be prone to damage when driven on. The invention provides surface matting for addressing this, comprising a first mat (1a) and a second mat 1b, each mat having a series of substantially parallel beams (2), a plurality of spine rods 3 that run substantially perpendicular to and through the beams and connect the beams to one another. Each mat also has a joiner (7) adjacent an edge of the mat, arranged so that one of the spine rods passes through the joiner. The matting is such that the first and second mats are connected to one another by way of a connecting rod 8 that passes through and connects the joiner (8) of one mat to the joiner of the other mat.

데크로드의 목재 데크를 구축하기 위한 것으로서, 데크목이 놓여지는 삽입공간의 하부에 위치하여 상기 데크목을 상향 지지하는 지지플레이트와, 지지플레이트의 양 측단에 위치하는 지지채널로 이루어지되, 상기 지지플레이트에는 길이방향으로 배수공의 다수 개가 구비되고, 상기 배수공의 테두리면에는 하광상협의 상방쐐기가 일정한 간격을 두고 설치되어 상기 데크목이 고정 지지될 수 있도록 하면서, 서로 인접한 상방쐐기들 사이에는 상기 배수공과 연통하는 배수구가 형성되도록 구성되는 것을 특징으로 한다.

A board, and a method of forming a board, including a first side and a second side, the first side opposed to the second side. The first side of the board includes at least one groove extending substantially across the first side, and the board includes at least one drainage port extending from said at least one groove to the second side.

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 a loop portion which is receivable in an opening of the industrial mat, such that said loop portion in a storage position is maintained at or below the working surface.

A method of making a modular engineered wood composite road (40) includes determining a bearing strength of the soil at a location where the modular engineered wood composite road will be installed; determining a bearing strength of the soil at a location where a modular engineered wood composite road (40) will be installed; determining a flexural strength and stiffness required for the modular engineered wood composite road (40) based on the determined bearing strength of the soil at the location where the modular engineered wood composite road (40) will be installed; assembling a plurality of engineered wood composite billets (46) from a plurality of composite wood laminations, wherein each engineered wood composite billet (46) has the required flexural strength and stiffness; and assembling the engineered wood composite billets (46) to define the modular engineered wood composite road (40).
