Abstract
Elongate profiled object having a cross section, the object comprising a peripheral wall, forming a hollow profile extending in a longitudinal direction, wherein at least part of the peripheral wall is provided with a reinforcement element, and wherein the elongate profiled object is made of a thermoplastic material.
Claims11
Elongate profiled scaffold planks, each comprising:
- an outer peripheral wall, forming a hollow profile extending in a longitudinal direction between opposite open-end portions,
- wherein the outer peripheral wall defines a rectangular shaped cross section, and
- the outer peripheral wall comprises:
- first and second longitudinal profile sidewalls that are widthwise spaced apart from each other;
- and
- an upper wall and a bottom wall that are height-wise spaced apart from each other,
- wherein the hollow profile is defined by one or more longitudinal interior cavities extending within the outer profile wall, between the opposite open-end portions, and
- wherein the elongate profiled scaffold planks are formed of a thermoplastic material that is fiber filled,
- wherein a reinforcement element is provided in the upper wall and the bottom wall,
- wherein the reinforcement element comprises an embedded layer of continuous fiber tape or unidirectional tape extending in the longitudinal direction between the opposite open-end portions,
- wherein the reinforcement element includes at least one fiber monofilament extending in the longitudinal direction, and
- wherein the embedded layer is covered by an outer layer of the thermoplastic material, so that the upper and bottom walls form a laminate;
- and
- wherein:
- a first one of the elongate profiled scaffold planks further comprises:
- a first connecting elements formed longitudinally along one of the first and second longitudinal profile sidewalls, to connect with a second one of the other elongate profiled scaffold planks;
- wherein the first connecting elements comprises a pair of U-profiles that are height-wise spaced apart from each other, each one of the pair of U-profiles being connected by its legs to the one of the first and second sidewalls so that one of the pair of U-profiles is located at the upper wall and another one of the pair of U-profiles is located at the bottom wall;
- and
- a second one of the elongate profiled scaffold planks further comprises:
- a second connecting element formed longitudinally along one of the first and second longitudinal profile sidewalls, to connect with the first one of the elongate profiled scaffold planks;
- wherein the second connecting element comprises one U-profile connected by its legs to the one of the first and second sidewalls so that the one U-profile is located at a height-wise center to the one of the first and second sidewalls and fits between the pair of U-profiles of the first one of the elongate profiled scaffold planks to interconnect the first and second ones of the elongate profiled scaffold planks.
