摘要

Method for the continuous production of sandwich boardsfor scaffolding and/or formworks obtained by the pultrusionsystem, the boards comprising an inner filling body (11) andat least one outer reinforcement layer (12) to cover at leastthe longitudinal faces of the board, the outer reinforcementlayer (12) comprising continuous fibre material in continuousthread form and/or continuous wave form and/or continuous matform, the continuous material being impregnated with resin andmade to travel under traction inside a formation andpolymerization mold (13) and subsequently cut to size, theinner filling bodies (11) being fed to the formation andpolymerization mold (13) without substantial discontinuity inthe form of geometrically finished element sin a substantiallycentral position with respect to the continuous fibre materialswhich constitute the multi-layered outer reinforcement part(12).Sandwich board for scaffolding and formworks obtained bythe pultrusion method and comprising an inner filling body (11)associated with a multi-layered covering part with the functionof reinforcing and protecting, the multi-layered covering part(12) comprising a first inner layer (12a) made of a single-threadMAT material in fibreglass reinforced with resin, asecond intermediate layer (12b) made of a multi-layered matattached to a fibreglass base and an outer layer (12c) made ofa veil of non-woven material.
