Abstract: The invention relates to a sandwich panel (100) comprising a facing element (110) and a layer of insulating material (130), the facing element (110) comprising a facing sheet (111) and anchoring means (114) able to hold the facing element (110) in engagement with the layer of insulating material (130) so as to attach the facing sheet (111) mechanically to the layer of insulating material (130). The sandwich panel is particularly resistant to climatic conditions, mechanical impacts as well as the risk of delamination.

Abstract: The invention relates to a temporary construction that includes a roof panel (201), a facade panel (111), and a component for attaching (204) the roof panel (201) to the facade panel (111), the attachment component (204) having one end intended to be attached to the roof panel and one end intended to be attached to the facade panel, one of the ends of the component including a hook able to engage with an orifice (212) provided in one of the panels (201, 111) or in an element (202) attached to the panel, in order to tension the component (204) so as to keep the roof panel (201) supported on the facade panel (111). The component may to advantage include a length adjustment means to tighten the attachment if necessary.
