Interlocking laminated support mat

Abstract

A laminated one-ply support mat comprised of a plurality of individual wood hat includes means for transferring load and interlocking with an adjacent one-ply The laminated one-ply support mat may be suitable for the construction of ads, flooring, or platforms to support heavy equipment. The laminated one-ply ay include a non-laminated member fastened to each side to prevent damage to the laminated support mat. The laminated one-ply support may be comprised of a individual wood laminations fastened together by a plurality of nuts and bolts support mat to be disassembled and repair in the field.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 11 / 011,724, filed Dec. 14, 2004, entitled “Laminated Support Mat,” which is a continuation-in-part application of U.S. patent application Ser. No. 10 / 377,099, filed Feb. 28, 2003, entitled “Method of Making Laminated Wood Beams With Varying Lamination Thickness Throughout the Thickness of the Beam,” which claims priority to U.S. provisional application Ser. No. 60 / 394,814, filed Jul. 10, 2002, each of which is incorporated herein in its entirety by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to an improved laminated one-ply support mat that may interlock with adjacent one-ply support mats to form a temporary road, platform, or flooring. The improved laminated one-ply support mat may be used as a support surface or pathway for heavy equipment to access remote areas to conduct ...

Problems solved by technology

These conditions often make it difficult to access with vehicles and equipment necessary for the exploration and drilling operations.

The nails however can lead to flat tires of equipment, which are often difficult to have repaired due to the remote location of the site.

These systems thus require large amounts of time and manual labor to install and remove.

Additionally, individual boards are often damaged during removal such that they are unsuitable for reuse.

The wood panels are typically untreated with preservative chemicals because of environmental concerns.

Because the timber used to form the panel 10 is expensive, the panel 10 is very costly.

Further, the roadway formed by the panels 10 is very costly because tens of thousands of the panels 10 may be needed for a single construction project.

The use of multiple layer mats has been able to decrease the amount of labor and have been a benefit to the exploration and drilling for oil and gas, but some difficulties do exist in the construction of temporary roads and flooring.

The use of nails to fasten the mat layers together may lead to flat tires on equipment used in these remote areas.

This can be a difficult and frustrating problem because of the remote locations may make it difficult to have the tires repaired.

The weight of each individual multiple layer mat can also present a number of difficulties.

Additionally, the addition of a layer increases the overall size of the mat.

Increases in weight and size may increase both the transportation and the installation costs.

As the road is built, the distance between the storage location and the end of the road increases causing the equipment to travel farther between trips.

Thus, larger mats requ
