Mat assembly used in construction and mat assembly construction and repair methods used in construction

摘要

The mat assembly 10 used in construction includes a plurality of pleated plates 22 disposed between at least some of the plastic beams to provide additional strength and stiffness to the mat, and a plurality of composite beams ( 20). Plastic beams can be made of a composite material with a generally rectangular cross section. The pleat plate has a width (vertical height) when placed between adjacent beams that is less than the width of the beam (vertical height), so that the pleat plate can be concave above and below the top (12) and bottom (14) surfaces of the mat, respectively. have. A number of rods 24 extend laterally through the beam and plate to compress the beam and plate for each. The pleated plate may be a metal or fiber reinforced resin, and includes a slotted hole 28 to cause the beam to contract longitudinally in response to environmental changes. A method of constructing or repairing a composite mat is also disclosed.
