LAMINATED MAT WITH ENDCAP
An improved laminated mat is disclosed and includes a plurality of layers and end caps. The plurality of layers may be formed of wood, synthetic materials, wood, metal, or a combination of such materials. The end caps may form longitudinal edges of the laminated mats, and may have an outer region having a thickness equal to a total thickness of the plurality of layers. The outer region of the end caps may provide improved performance of the laminated by reducing wear and tear of the laminated mat. In an additional aspect, the laminated may include attachment means recessed within the plurality of layers, and may include a cover plate that overlies the attachment means and is flush with a top surface of the laminated mat.
The present disclosure is generally related to laminated mats, and more specifically to systems and methods for providing endcaps for laminated mats.
BACKGROUNDLaminated mats are in broad use in many industries. However, presently available laminated mats have several deficiencies that affect their performance and reduce their useful life. For example, many laminated mats are constructed from layers of wood, such as an untreated wood. During use, wooden laminated mats come in contact with the ground and moisture, which may cause the wooden laminated mats to begin deteriorating or rotting. Typically, the deterioration or rotting of wooden laminated mats begins at the edge, where the layers of the wooden laminated mat are directly exposed to the moisture. As the edges rot, the layers of the laminated mat may begin to separate, which may increase the rate at which the wooden laminated mat rots. Further, the separation of the layers may cause the wooden laminated mats to warp, creating an uneven surface, which may introduce tripping hazards to persons working in areas where such wooden laminated mats are present. Additionally, the rotting of the wooden laminated mat may significantly decrease their useful lifespan. For example, the useful life of wooden laminated mats is often less than 1 year, and may be significantly shorter (e.g., 6 months) due to the deficiencies described above. Thus, replacing the wooden laminated mats once or twice a year imposes significant costs to industries (e.g., the oil and gas industry) where such laminated mats may be deployed.
In addition to deficiencies (e.g., rotting) caused by weather elements (e.g., moisture, extreme heat, etc.), wear from continued use and/or damage from heavy equipment used in the field can cause individual pieces of wood used to construct the wooden laminated mats to disintegrate and fall from the mats over time. This disintegration causes loss of compression and torque of the bolts and/or nails holding the mat together, which may cause the wooden laminated mat to be no longer useable or to lose its structural integrity. Additionally, the wear from continued use and/or damage from heavy equipment may increase the likelihood that rot occurs, and may increase the rate at which the layers of the wooden laminated mat separate. This may also cause the useable life of the wooden laminated mat to decrease.
Another type of mat may be referred to as a synthetic mat. While synthetic mats generally do not have the same rotting problems as wood mats, synthetic mats are not in wide use due to various disadvantages. For example, in the event that there is rain at a location where the synthetic mats are deployed, water tends to stay on top of the laminated synthetic mats, thereby causing slippery conditions. Synthetic mats also tend to be more labor intensive to deploy. Moreover, synthetic mats generally have continuous top surface and a hollow core. Because of this, if the mat is ever pierced, water fills into the core and causes the synthetic mat to be much heavier, which creates difficulties in transporting and deploying the mats. Further, if the synthetic mats are utilized in a cold environment, water expansion in the presences of freezing conditions further damages the mats. Another disadvantage of synthetic mats is that because they generally comprise one large piece of surface material, they generally are not repairable in a cost-effective manner in the event that the mat is damaged.
Another type of mat is a laminated synthetic mat. While laminated synthetic mats are not as susceptible to rot as wooden laminated mats, laminated synthetic mats remain susceptible to separation of the layers under normal wear and tear. Such a separation reduces the useful life of the laminated synthetic mats. For example, forklifts are often used to transport the mats (e.g., both laminated synthetic mats and wooden laminated mats) to a location where the mats are to be deployed or stored. If the forklift operator inadvertently catches the edge of the mats with the forks of the forklift, the forks may slide between the layers of the laminated mats, damaging the areas immediately surround the impact zone and separating the layers of the laminated mat.
BRIEF SUMMARYSystems, apparatuses and methods which provide for an improved laminated mat comprised of synthetic material, wood, or other materials are provided for herein. Such mats may include a plurality of inventive features. For example, in some embodiments the laminated mat may include one or more end caps configured to reduce the likelihood that layers of the laminated mat are separated during movement, use, and transport, and may reduce the wear and tear of the laminated mate, and may increase the useful life of the laminated mat.
In an additional or alternative embodiment, the laminated mat may comprise a cover plate that may reduce a likelihood that persons working in areas where the laminated mat may be deployed are injured. For example the laminated mat may include attachment means that may be recessed with respect to the top surface of the mat. Such attachments means may present a potential hazard that persons working in the area of the laminated may trip on. The cover plate may overlie the attachment means and substantially fill the recessed area where the attachment means is located, and may be seated flush with the top surface of the laminated mat, thereby eliminating the potential tripping hazard.
The foregoing has outlined rather broadly the features and technical advantages of the present disclosure in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the embodiments will be described hereinafter which form the subject of the claims of the present disclosure. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims. The novel features which are believed to be characteristic of the present disclosure, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.
For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
Referring to
In an embodiment, the layers 120, 130, 140 of the laminated mat 100 may be constructed from a plurality of individual boards, as shown in
In an additional or alternative embodiment, the layers 120, 130, 140 may each be formed as single continuous sheet, rather than as a plurality of individual boards. For example, the first layer 120 may be formed from a first continuous sheet of material, the second layer 130 may be formed from a second continuous sheet of material, and the third layer 140 may be formed from a third continuous sheet of material. The sheets may then be attached (e.g., bolted, nailed, glued, etc.) to form the laminated mat 100.
It is noted that constructing the laminated mat 100 from individual boards, rather than layers of sheets, may provide advantages. For example, the individual boards may be spaced apart to allow water to drain through the laminated mat 100, whereas the continuous sheets may not allow water to drain through the laminated mat 100. Thus, when single continuous sheets are used to form the laminated mat 100, additional work may need to be completed prior to deployment of the laminated mat 100, such as to create slight gradient in the area where the laminated mats are to be deployed so that the water will run off the top surface of the layer 120. Further, by forming the laminated mat 100 from individual boards, rather than continuous sheets, individual boards of a particular layer of the laminated mat 100 may be replaced without requiring replacement of the entire particular layer.
In an embodiment, the third layer 140 may include metal channels 142, as shown in
Additionally, as shown in
For example, and referring to
In additional or alternative embodiment, the channel of the end caps 110 may receive more than 1 layer of the laminated mat 100. For example, if the laminated mat 100 included 4 layers, the channel may be configured to receive the second and third layers (e.g., the middle layers). As another example, if the laminated mat 100 included 5 layers, the channel may be configured to receive the second and third layers (e.g., the middle layers). Further, the channel may receive less than all of the middle layers in some embodiments. For example, if the laminated mat included 4 layers, the channel may only receive the second layer, or the third layer, but not both, or may receive portions of the second and third layers. In yet another additional or alternative embodiment, the channel of the end caps 110 may receive only a portion of one or more layers of the laminated mat 100. For example, if the laminated mat 100 included two layers, the channel may receive a portion of the two layers, such as by milling the two layers along the longitudinal edges to form rabbets that are adjacent on each of the layers (e.g., form a tongue) that may be inserted into the channel while maintaining the top and bottom surfaces flush with the top and bottom surfaces of the end cap 110. The end caps 110 may reduce penetration of moisture between the layers 120, 130, 140. For example, because an outermost edge of the laminated mat 100 may correspond to the outer edge 310 of the end caps 110.

Furthermore, and as illustrated in
Referring to
By using the cover plate 400 in conjunction with the laminated mat 100, work place injuries caused by workers tripping while walking through a work site where the laminated mat 100 is deployed. For example, as explained above, the attachment means 150 may be recessed within the first layer 120 of the laminated mat 100 by securing the attachment means 150 to the second layer 130 (e.g., at a region 162 of
Referring to
In an embodiment, the method 500 may include additional steps (not shown in
Laminated mats constructed according to the method 500 may provide improved laminated mats. For example, because the laminated mats include end caps along the longitudinal edges (e.g., high impact, high traffic areas), the laminated mats may be more resistant to wear and tear. Additionally, by providing cover plates in some embodiments, a likelihood of injury to workers that are working in areas where the laminated mats are deployed may be reduced or eliminated.
