    摘要: Scaffolding element (100) with insulation, said scaffolding element (100) comprising a frame (110) of metal braces (111) and a set of fastening means (120), arranged to fasten the scaffolding element (100) to a supporting structure (20) of a scaffolding structure (10).
    The invention is characterised in that the scaffolding element (100) furthermore comprises a block (130) of insulating material, and in that the block (130) is cast around the frame (110), so that the frame (110) is completely covered by said insulating material but so that the fastening means (120) are not covered by said insulating material.
    The invention also relates to a manufacturing method and a kit of parts.

    摘要: A bending method and a bending device, wherein a composite bar comprising a bundle of reinforcing fibres embedded in a polymer matrix is bent at a bending point. To make it bendable, the composite bar is heated locally at the bending point using an ultrasonic device with a sonotrode. After the bending point has been heated, an infeeding movement between the composite bar and the sonotrode is used to deform a region of the composite bar at the bending point to create a deformed portion of which the outer dimensions are different from the outer dimensions of the bar portions of the composite bar adjoining the bending point. The two bar portions are then moved or angled away in relation to one another, and so the composite bar is curved at the bending point. Once the desired bending has been achieved, the composite bar is cured at the bending point.

    摘要: The present invention discloses a foldable FRP plate, comprising a plurality of first regions and one or a plurality of second regions which are integrated in one piece; the second region is located between two adjacent first regions, so that the adjacent first regions being folded and unfolded relative to each other with the second region as a rotating shaft; the first regions are plate-like products manufactured by impregnating fiber woven fabric with resin for curing, are rigid and cannot be folded; the second region is flexible fiber woven fabric and has a width being two times a design thickness of the FRP plate. The present invention also discloses a manufacturing method, including laying the fiber woven fabric according to a design thickness and a layer layout; dividing the first regions and the second region according to an origami design method.
