- the flexibility of the wire ropes enables the [52] US. Cl. ..94/13, 52/588, 238/14 assembly to be rolled up and unrolled and, when the [51] Int.
- the present invention relates to assemblies of interlinked pre-fabricated members for forming a path covering a strip of ground. Such a path may find use as a temporary road surface or as an emergency diversion route when road works are in progress.
- known tracks formed of open mesh or of similar open forms of construction provide only an uneven surface over which, because of its irregularity, vehicles can proceed only slowly.
- Such and other known tracks are formed of members which merely lie on the surface of the ground and are consequently prone to be displaced by vehicles passing over them.
- the members are each provided with portions tending to penetrate the surface on which they rest to improve the positional stability of the path and with other portions which may easily be arranged to provide an even surface over which vehicles may travel at considerable speed.
- an assembly for covering a strip of ground to provide a path comprising a plurality of prefabricated members, flexible means so interlinking the members as to enable the assembly to be rolled up and unrolled, the members being maintained in mutually adjacent relationship by the flexible means to provide, when the assembly is unrolled over a strip of ground, a substantially continuous cover over the strip.
- FIG. 1 shows a vertical cross-sectional view in perspective of two adjacently disposed pre-fabricated members of an assembly embodying the invention
- FIG. 2 shows a representation similar to FIG. 1 with a modified construction of the assembly
- FIG. 3 shows a representation perspective of three prefabricated members of another assembly embodying the invention.
- the members 1 each include a channel-shaped portion of approximately U-shaped cross-section, which is composed of downwardly pointing legs 2 and 3 and an approximately planar sheet portion 4 connecting these legs 2 and 3.
- the members 1 are flexibly interlinked by means of wire ropes 5, indicated in FIG. 1.
- These members 1 are maintained on the wire ropes 5 predetermined distances relative to each other by conventional means such as for example disclosed in French Pat. No. 866,878, and German published utility model No. 1,976,650. When unrolled over a strip of ground, they form a path substantially covering the whole of the strip. The width of the path is defined by the length of each of the members in a direction perpendicular to that of the path.
- Each of the members 1 also comprises substantially horizontally projecting flange portion 7 and 8, which may be welded on to the respective channel-shaped portion. The flange portions 7 and 8 extend along the lengths of the members and cover the gaps 6 between adjacent members 1. In FIG.
- each member 1 is provided with flange portions 7 and 8 on both longitudinal sides, and each flange portion covers approximately half the width of the adjacent gap 6 in a direction parallel to that of the path.
- the flange portions 7 and 8 lie in the plane of the sheet portion 4 of the members 1.
- the flange portions 7 and 8 may be slightly downwardly displaced out of the plane of the respective sheet portion 4, whereby an increase in the stability of the upper surface of the assembly forming the path may be obtained.
- the widths of the projecting flange portions 7 and 8 of successive members may be of an altematingly different lengths provided the projecting flange portions of adjacently disposed members substantially cover the area of each gap 6 between respectively adjacent members.
- the flange portions of adjacent members 1 closely adjoin or abut against each other.
- theprojecting flange facing flange portions of two adjacent members overlap each other when the assembly is unrolled to form the path.
- the projecting flange portions covering each gap may be altematingly arranged at difierent levels.
- each member 1 is provided with only one flange portion 9 projecting along one longitudinal side of the respective channel-shaped portion of the member 1.
- Each flange portion 9 projects over at least the whole of the corresponding gap 6.
- the width of each flange portion 9 exceeds, in the example shown in FIG. 2, the width of the corresponding gap 6; hence the outer end of each flange portion rests on the respectively adjacent member 1.
- each member 1 is preferably provided on the upper surface formed by the sheet portion 4 with a recess 4", which in turn forms the support for the overlapping end of the flange portion 9 of the respectively adjacent member 1'.
- each recess 4" is preferably somewhat greater than the width of the overlapping portion of the flange portion 9, so as to facilitate the rolling-up of the assembly.
- the form of construction shown in FIG. 2 proportions may be so constructed, that vides the additional advantage of greatly reducing the tendency of a member 1' to tilt due to the flange portions being unevenly loaded along their length.
- the members 1 are shown to be welded to the corresponding projecting flange portions 7 and 8 whilst in FIG. 2, the members 1 are shown to be integral units bent into shape so as to provide flange portions 9. It is to be understood, that the members 1 of FIG. 1 may alternatively be constructed as integral units bent into shape; similarly, the members 1' of FIG. 2 may alternatively be of welded construction.
- the projecting flange portions may be arranged along the lower edges of the downwardly pointing U-legs 2 and 3; such a profile is particularly simple to form by constructing the projecting flange portions as bent flanges, whereby a somewhat hat-shaped profile results.
- the individual members 10 comprise a downwardly open channel-shaped profile of approximately U-shaped cross-secton, which is composed of downwardly pointing legs 12 and 13 and an approximately planar sheet portion 14 connecting these legs 12 and 13.
- the members 10 are flexibly interlinked by wire ropes 15, or in any other suitable manner, to define gaps 16 between adjacent ones of the members 10.
- the gap 16 between two adjacent members 10 is covered over by projecting flange portions 17 and 18 which extend over the length of their respective members l0, i.e., over the width of the path.
- the flange portions 17 and 18 are formed as folded flanges and are located at the longitudinal lower edges of the downwardly pointing U-legs 12 and 13.
- the members 10 exhibit a somewhat hat-shaped cross-sectional profile.
- the flange portions 17 and 18 are so arranged that as illustrated in the example represented in FIG. 3 of the drawing they define with the respective one of the downwardly pointing U- legs 12 and 13 an angle a of more than 90.
- an edge 19 is provided in the middle of the gap 16, where the flange portions 17 and 18 of adjacent members 10 are close to or abut each other. This edge 19 promotes penetration into some kinds of soil or sub-strates and tends to stabilize the laid assembly against accidental displacement of the path.
- This form of construction also facilitates penetration of certain kinds of soil into the U-profile of the channel-shaped portions of the members 10 forming the assembly.
- the downwardly pointing U-legs 12 and 13 are not mutually parallel but diverge towards their lower extremities, thereby causing the channel of the members 10 to be of trapezoidal cross-section.
- This construction promotes loosening of the soil pressed into the channelshaped profile when the assembly is rolled up.
- the flange portions 17 and 18 may as already described be arranged'either to project perpendicularly of the legs 12 and 13 or to define an angle a of more than 90 to legs 12 and l3.
- each of said members comprising a channel-shaped portion and at least one flange portion projecting from the respective channel-shaped portion, said channel-shaped portions of respective ones of said members being mutually spaced apart along saidflexible means to define gaps therebetween and said flange portions extending across the length of said strip and substantially covering said gaps between adjacent ones of said channel-shaped portions.
- each of said channel-shaped portions comprises a sheet portion adapted to form part of the upper surface of said cover when said assembly is unrolled, and each flange portion projects at substantially the same level as the sheet portion of the respective one of said channel-shaped portions.
- each of said members comprises only one of said projecting flange portions, each said one flange portion projecting from one side of the respective one of said channelshaped portions and extending over substantially the area of said gap between adjacent ones of said channelshaped portions.
- each said channel-shaped portion comprises a sheet portion adapted to form part of the upper surface of said cover when said assembly is unrolled and each said one projecting flange portion at least partially overlaps said sheet portion of the next adjacent one of said channelshaped portions.
- each said channel-shaped portion is disposed below the upper surface of the flange portion projecting from the respective channel-shaped portion to define a recess to accommodate the overlapping flange portion of the next adjacent channel-shaped portion.
- each of said members comprises a channel-shaped portion and at least one flange portion welded to the respective channel-shaped portion.
- each of said members comprises a channel-shaped portion and at least one flange portion integral with the respective channel-shaped portion.
- each of said channel-shaped portions is of a substantially U- shaped cross-section.
- each flange portion is integral with said channel-shaped portion of the respective one of said members.
- An assembly for covering a strip of ground to provide a path comprising in combination:
- An assembly for covering a strip of ground according to claim 16, wherein the means substantially bridging the gap between successive vertical webs comprises flanges secured to the bottom edges of successive webs and extending respectively forwardly and rearwardly of successive webs so that their free edges closely confront each other.
