A composite floor structure and method of making the same are disclosed. The composite floor structure may include a platform and a plurality of transverse beams. The composite floor structure may also include at least one longitudinal beam and a plurality of insert beams to accommodate the longitudinal beam. The composite floor structure may also include an underlayment between the plurality of transverse beams and the at least one longitudinal beam. Some or all of these components may be integrally molded together to form a fiber-reinforced polymer structure. The composite floor structure may be used for cargo vehicles and other applications.

The present invention relates to a grid deck with shear-resisting plates and the assembly of the grid decks. The shear-resisting plates are pre-cast in the grid deck and protrude from the side surfaces thereof. When the grid decks with shear-resisting plates are assembled, they are laid on the beams with the shear-resisting plates contacting the beams and without the grid decks contacting the beams.

Apparatuses and methods of operating the same are described. A plank connector that includes a body and a platform. The body may be on a first plane. The platform may be connected to the body. The platform may be on a second plane perpendicular to the first plane. The platform may include a first wing and a second wing. The first wing may extend outwardly along the second plane from the platform. The first wing may be shaped to be inserted into the groove of the first plank. The second wing may extend outwardly along the second plane from the platform. The second wing may be shaped to be inserted into the groove of the second plank.

A method or device for creating a plank. The device may include a container with an opening to receive a material. The device may also include a beam extending from a side of the container to a point in an open space of the container. The beam may have a curved shape. A portion of the material may form around the beam.

An insulation system and method comprising an insulation layer, an atmospheric regulation layer, a structural support, and an external surface; wherein the atmospheric regulation layer is supported by the structural support, wherein the insulation layer is located between the atmospheric regulation layer and the external surface, wherein the atmospheric regulation layer has a water vapor permeability of not greater than 3 perms at a relative humidity of 25% as measured by ASTM E96 Procedure A Dry Cup, and a water vapor permeability of at least 6 perms at a relative humidity of 75% as measured by ASTM E96 Procedure B Wet Cup, wherein the atmospheric regulation layer has a fire class A rating as measured by ASTM E84, and wherein the continuous atmospheric regulation layer has a ACH50 value of not greater than 10, wherein ACH50 represents an air exchange at 50 Pascals.

An arena apparatus for staging a sport is provided. The apparatus includes a floor having a perimeter; and at least one wall coupled to the floor at the perimeter and extending upwardly and outwardly from the floor at an angle relative to an axis perpendicular to the floor, wherein the angle of the wall prevents an athlete from standing on the wall.

A structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.

A decking clip to allow a plurality of decking members to be attached relative to a support assembly, the decking clip including an elongate plastic body strip having a body length, the body provided with a number of openings to receive fasteners there through to attach the body relative to the support assembly, a number of upstands spaced over the body length and extending substantially perpendicularly from the body strip, substantially transversely to the body length, each upstand having at least two opposed decking board engagement arms, a first decking board engagement arm extending from a first lateral side of the upstand at an acute angle and a second decking board engagement arm extending from a second lateral side of the upstand at an acute angle, at least two centering members, at least one centering member extending from the first lateral side of the upstand between the first decking board engagement arm and the body strip and at least one centering member extending from the second lateral side of the upstand between the second decking board engagement arm and the body strip, each upstand and/or engagement arm being resiliently deformable to allow portion of a decking board to pass and to retain the decking board relative to the support assembly in a spaced apart, non-overlapping configuration.

A lightweight universal panel mat (100, 400, 500, 600, 700, 800, 1100, 1500, 1800, 2005, 2010, 2015, 2020) made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the mat and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The panel mats have first, second, third and fourth sides (110,120,135,145) that are configured to matingly engage or connect to the second, third, fourth and first sides, respectively. The connection can be by insertion or snap-locking of one side to another, or by the use of fastening elements that more securely holds the sides together. Thus, similarly configured panel mats can be connected by interlocking to form a temporary support surface, deck, walkway or roadway. Additional side ramps (2030) and adapters (2050) can be used to facilitate installation of the mats (2005, 2010, 2015, 2020) and access to the upper surfaces of the joined mats.

The present invention relates to a grid deck with shear-resisting plates and the assembly of the grid decks. The shear-resisting plates are pre-cast in the grid deck and protrude from the side surfaces thereof. When the grid decks with shear-resisting plates are assembled, they are laid on the beams with the shear-resisting plates contacting the beams and without the grid decks contacting the beams.
