Each triangular shapedgusset 118 includes has three sides: 118 a, 118 b and 118 c, wheresides gusset 118 includes a centrally disposed circular oroval aperture 119 configured to allow therig mat assembly 10 to be handled via a 4-way rigging system of a suitable crane or other piece of equipment and also to provide an attachment aperture for thelinks 350, which lock therig mats 10, into a modular matrix. In this embodiment,gussets 118 are approximately ½″ thick andapertures 119 are approximately 4″ in diameter. Twogussets 118 are butt welded to onelongitudinal channel 112 and onehorizontal channel 114 at each joint 115, with twogussets 118 coupled to the pair ofcurved edges FIG. 3 . - Longitudinal beams 130 have an “I” shaped cross-section (i.e., I-beams), a pair of terminal ends 130 a, a web 131 having a pair of side surfaces 136, an
upper flange 132 and alower flange 134. In this exemplary embodiment, beams 130 comprise a steel alloy, have a height of approximately 5½″ and a width of 5″ to 6″. However, in other embodiments beams 130 may have dimensions that differ from those of the beams 130 illustrated inFIGS. 1 and 2 . Also, in this embodiment beams 130 weigh approximately 15 pounds per foot. In other embodiments, beams 130 may weigh approximately between 10-30 pounds per foot. Beams 130 are disposed parallel with and offset fromaxis 15 and extend betweenhorizontal channels 114, with each terminal end of the two beams welded to thechannels 114 to secure them in place. Each I-beam 130 also includes a pair ofweb extensions lower flanges extensions inner surface 114 a of eachchannel 114, allowing for the welding of each I-beam 130 tochannels 114. In this arrangement, beams 130 are configured to transfer and distribute loads applied to the glulam beam assembly to theperimeter frame 110 of therig mat assembly 10. Beams 130 are also configured to provide clearance forstraps 150 to engageupper flange 132 andlower flange 134 of beams 130 and theinner surfaces 112 a oflongitudinal channels 112, as shown inFIG. 1 . In order to allowstraps 150 to engage beams 130 andchannels 112, the height of each beam 130 is at least slightly less than the height ofchannels 112. In this embodiment, the height of beams 130 is approximately ½″ less than the height ofchannels 112. As will be discussed further herein, beams 130 are disposed such that the upper surface ofbeam assembly 200 is in engagement with the lower horizontal surface offlange 132 and the upper horizontal surface offlange 134 of each I-beam 130. Referring toFIGS. 2, 4A and 4B ,glulam beam assembly 200 generally comprises acentral glulam beam 205 and twoouter glulam beams - In this embodiment, glulam beams 250, 230 and 250 are formed from Douglas-fir. However, in other embodiments beams 250, 230 and 250 may be formed from other types of wood. Each beam has a first longitudinal end (205 a, 230 a and 250 a), a second longitudinal end (205 b, 230 b and 250 b) a first side (205 c, 230 c and 250 c) and a second side (205 d, 230 d and 250 d). Each
glulam beam glulam beam assembly 200 overall. Further,glulam beam assembly 200 is configured to have a bridge strength approximately equal to the strength offrame assembly 100. In this manner,beam assembly 200 is configured to fail in response to an applied load at approximately the same time asframe 100. In other words, the load required to cause structural failure ofbeam assembly 200 is approximately equal to the load required to cause structural failure offrame assembly 100. Such a feature may act to mitigate any bottlenecks in the strength ofrig mat assembly 10 such that the strength of bothbeam assembly 200 andframe assembly 100 are used efficiently. For instance, stresses applied toassembly 10 will be shared equitably between thebeam assembly 200 andframe assembly 100, such thatassembly 200 andassembly 100 are configured to fail at a relatively similar stress applied toassembly 10. - Referring specifically to
FIGS. 4A and 4B ,central beam 205 is shown. In this embodiment,beam 205 forms a three-dimensional matrix of wooden, finger-jointed beams or lams. Specifically,beam 205 generally includes six columns or billets 210 a-210 f (FIG. 4B ), each comprising four rows of lams 211 a-211 d. The first orupper row 211 a of billets 210 a-210 f comprise a firstouter lam 212 forbillet 210 a, fourinner lams 214 forbillets 210 b-210 e and a secondouter lam 216 forbillet 210 f.Outer lam 212 includes a first orouter face 212 a and a second orinner face 212 b.Lam 212 further includes a longitudinally extendingouter groove 212 c proximalfirst face 212 a and alongitudinally extending notch 212 d atsecond face 212 b Inner lams 214 also include afirst face 214 a and asecond face 214 b. Atongue 214 c extends perpendicularlyrelative axis 15 from thefirst face 214 a of eachlam 214. Also, agroove 214 d extends perpendicularlyrelative axis 15 into thesecond face 214 b of eachlam 214.Lam 216 has afirst face 216 a, asecond face 216 b, atongue 216 c extending fromfirst face 216 a and agroove 216 d proximalsecond face 216 b. Eachtongue grooves rabbet 212 c oflam 212 allowslam 212 to physically engagelongitudinal channel 212. Specifically,first face 212 a oflam 212 may be inserted intochannel 212 to physically engageinner surface 212 a ofchannel 212. Further, groove 212 c allows the upper surface oflam 212 to sit substantially flush againstchannel 112. -
Second row 211 b andthird row 211 c of billets 210 a-210 f each include a first outer lam 220 (billet 210 a), four inner lams 222 (billets 210 b-210 e) and a second outer lam 224 (billet 210 f).Outer lam 220 includes a flat first face 220 a, asecond face 220 b and agroove 220 c extending intosecond face 220 b.Inner lams 222 each include afirst face 222 a, a second face 222 b, a tongue extending fromfirst face 222 a and agroove 222 d extending into second face 222 b.Outer lams 224 include afirst face 224 a having atongue 224 c extending therefrom and a flatsecond face 224 b.

Fourth row 211 d includes a first outer lam 228 (billet 210 a), four inner lams 230 (billets 210 b-210 e) and a second outer lam 232 (billet 210 f).Lams row 211 a. The inversion of the lams comprisingfourth row 211 d allows for the insertion ofouter lams channels 212 so they may engageinner surfaces 212 a ofchannels 212. The interlocking relationship provided by the engaging tongues and grooves is configured to strengthen rows 211 a-211 d. For instance, the interlocking relationship oflams row 211 a may allow loads applied tobeam 205 to be distributed acrossrow 211 a and to theframe assembly 100. - In an embodiment,
glulam beam 205 is formed by first adhering and pressing four rows of lams (e.g., finger-jointed wooden boards) vertically together, to form four columns or billets (e.g., billets 210 a-210 f), where each billet comprises four vertically stacked lams (e.g. rows 211 a-211 d). Adhesive is applied to the upper and lower surfaces of the two middle lams (e.g., lams 220 ofbillet 210 a), while the uppermost lam (e.g.,lam 212 ofbillet 210 a) includes adhesive on its lower surface and the lowermost lam (e.g.,lam 228 ofbillet 210 a) includes adhesive on its uppermost surface. Next, tongues, grooves and rabbets are formed on the lams of each billet. In an embodiment, the billets comprise billets 210 a-210 f, and thus, comprise the lams of rows 211 a-211 d. Following the process of forming billets 211 a-211 f,beam 205 is formed by adhering and pressing each billet horizontally together. In this step, adhesive is applied the two side surfaces of the inner lams (e.g., lams 214, 222 and 230), thesecond face lams lams beam 205 includes lams that are adhered vertically and billets adhered horizontally to provide for greater bridge strength. - In an embodiment, a urethane glue may be used as the adhesive for the step of forming billets 211 a-211 f and the step of adhering each billet 211 a-211 f to one another to form
beam 205. In an embodiment, lams are vertically pressed at a pressure of at least 125 pounds per square inch (PSI) to help form billets 211 a-211 f. Similarly, in an embodiment, billets 210 a-210 f are pressed together at a pressure of at least 125 PSI to formbeam 205. Glulam beams 230 and 250 are configured similarly tobeam 205, as shown inFIG. 2 . However, beams 230 and 250 each include a pair ofchamfers 232 and 252, respectfully, that are disposed at the intersection between each longitudinal end and a side. Specifically, chamfers 232 ofbeam 230 are disposed betweenends side 230 c. Chamfers 252 ofbeam 250 are disposed betweenends 250 a, 250 b, andside 250 d.Chamfers 232 and 252 are configured to provide clearance betweenbeams gussets 118 offrame assembly 100. - A plurality of perpendicularly or horizontally extending grooves or dados extend into the top surface of
row 211 a. Specifically, in this embodiment a central groove 234 is disposed longitudinally between a pair of outerhorizontal grooves 236. However, in other embodiments there may be no central groove 234. An identical set of grooves extend into the bottom surface offourth row 211 d in the same manner (not shown).Grooves 234 and 236 are configured to allowsteel straps 150 to extend intochannels 112, and to allow for their outside surfaces be disposed flush with the top of the glulam beams, as described above. Further, in this embodiment straps 150 are stitch welded to the upper andlower flanges mat assembly 10. As discussed above, I-beams 130 physically engage the glulam beams ofbeam assembly 200. Specifically, after assembly (as shown inFIG. 1 )side 230 d ofbeam 230 is in physical engagement withside surface 136 of one beam 130 and side 250 c ofbeam 250 is in physical engagement withside surface 136 of the other beam 130. Also, bothsides beam 205 are in physical engagement with aside surface 136 of each beam 130. In this arrangement, loads applied tobeam assembly 200 may be distributed to I-beams 130 andperimeter frame 110 to further strengthenrig mat assembly 10. - Having described an embodiment of a
rig mat assembly 10, embodiments of a rig mat system will now be described. Referring toFIG. 5 , an embodiment of arig mat system 300 is shown. In this embodiment,rig mat system 300 includes six rig mat assemblies 10 (shown withoutbeam assemblies 200 in the interest of clarity) coupled to each other via a plurality oflink assemblies 350. As will be described further herein,system 300 is configured to allow for flexibility and modularity in tailoring the footprint or square footage offered by the mat system to a particular industrial application. For instance,link system 300 may be used in different applications having different square footage requirements. Further,link system 300 provides for a relatively smooth working surface to increase safety during operation. - Referring to
FIGS. 6A-6D, 7A and 7B ,link assembly 350 generally comprises alink frame 360 and four fastener orbolt assemblies 380.Frame 360 includes a base 362 having fourelongate portions 362 a-362 d. Eachelongate portion 362 a-362 d includes anaperture 364 that extends through thebase 362. The fourelongate portions 362 a-362 d allow thelink assembly 350 to “link” or couple up to four adjacently disposedrig mat assemblies 10 together, as shown inFIG. 5 .Frame 360 further includes atab 366 that extends upward frombase 362 and includes an aperture or lifting eye for handlingframe 360. While the embodiment offrame 360 shown inFIGS. 6A-6D includes fourelongate portions 362 a-362 d, in other embodiments thelink assembly 350 may include only two elongate portions, thus only providing for the coupling of tworig mat assemblies 10. Also, while this embodiment oflink assembly 350 includes fourbolt assemblies 380, in other embodiments alternative types of fasteners may be used, such as studs, rivets, nonmetallic fasteners, and others. Some fasteners may include locking nuts for securing the fasteners to thelink assembly 350 while others may not include a locking nut for securing. - In this embodiment, each
bolt assembly 380 includes a fastener or threadedbolt 382, abase pedestal 384, abushing 386, acompression plate 388, awasher 390 and a lockingnut 392.

Once threaded through frame 360 (as shown inFIG. 6B ),bolts 382 are welded to thebase 362 offrame 360 to secure them into place. However, in other embodiments,bolts 382 may be coupled to theframe 360 in some other manner, or they may only be threaded intoframe 360 and not fixed thereto. - Referring now to
FIGS. 6A and 8 ,pedestal 384 is configured to fit within theaperture 119 ofgusset 118, thus acting as a floor that fits flush against the upper surface of thebottom gusset 118.Pedestal 384 is formed from rigid steel plate and includes an aperture to allow the passage ofbolt 382 therethrough. Bushing 386, having a hemispherical upper surface and a flat lower surface, is disposedadjacent pedestal 384 and is configured to radially expand upon the securing of lockingnut 392 onbolt 382, thereby securinglink assembly 350 to thebottom gusset 118 of therig mat assembly 10. Also, the pliability ofbushing 386 allows adjacentrig mat assemblies 10 coupled to linkassembly 350 to flex. For instance,adjacent mat assemblies 10 may flex when positioned over relatively uneven terrain. In this embodiment,bushing 386 is formed from polyurethane but in other embodiments the bushing may be formed from other flexible materials. Thecompression plate 388 having an aperture is disposed over thebushing 386. In this embodiment,plate 388 comprises steel and has a diameter slightly smaller thanpedestal 384, allowingplate 388 to pass throughaperture 119 of thebottom gusset 118. Last,washer 390 and lockingnut 392 are disposed over the compression plate. In this embodiment,washer 390 is a small grade 8 washer andnut 392 is a locking nut provided by Nylok®. - While embodiments have been shown and described, modifications thereof can be made by one skilled in the art without departing from the scope or teachings herein.
