Abstract
A rollable temporary roadway is composed of individual supporting elements (2) which are articulately connected by hinge-like joints (7), each of which is formed by a bead (5) and the associated recess of a claw (6). The joints (7) are looped by at least one cable (10), with the cable being guided below the joints. A reeling device (20) for rolling up an installed temporary roadway (1) includes a pipe (21), hub members (22) which can be mounted on the pipe, and a cable arrangement (32, 33, 34).
Claims14
A temporary roadway having first and second ends, the roadway additionally having a rolled state and an unrolled state wherein the roadway extends along a line between the first and second ends, comprising:
- a plurality of supporting elements which are disposed beside one another in the direction of the line when the roadway is in its unrolled state;
- a plurality of hinge means, disposed transverse to the line when the roadway is in its unrolled state, for articulatedly connecting said supporting elements to one another, each hinge means including a bead affixed to a respective supporting element and a claw affixed to a respective supporting element adjacent said bead, said claw having a recess which is engaged by said bead;
- and
- at least one cable which has loops and which is fastened to supporting elements at both ends of the roadway, each loop separately surrounding a respective hinge means.
A reel device for rolling up a temporary roadway having a rolled state and an unrolled state, the roadway additionally having a width, comprising:
- a pipe having a length that is greater than the width of said roadway;
- a pair of rotary bearings, each rotary bearing being disposed at a respective end of said pipe;
- a rod spaced apart from and parallel to said pipe;
- means for connecting said bearings and said rod;
- and hub members about which said roadway can be coiled, said hub members being configured to be pushed onto said pipe and retained there, wherein each hub member has a periphery and includes a plurality of elongated wooden blocks attached at the periphery, said blocks being disposed parallel to said pipe and having lengths that are less than half the width of the roadway.
