The aim of the invention is to improve the load-bearing capacity of formwork supports during shock-type stress that is effective especially perpendicular to or at an angle from the longitudinal axis of the support. Said aim is achieved by a formwork support which is made essentially of wood and is provided with a top chord, a bottom chord, and a web that connects the two chords. The web and/or at least one of the chords comprises at least one recess in at least one final area of the support, said recess being filled with a filling material that has shock-absorbing properties. The invention also relates to a method for producing such a formwork support.
L'invention concerne un support de coffrage constitué essentiellement de bois et comprenant une membrure supérieure, une membrure inférieure et une âme reliant ces deux membrures. L'objectif de l'invention est d'améliorer la résistance de ce support de coffrage aux sollicitations de type chocs, s'exerçant en particulier perpendiculairement ou de façon oblique par rapport à l'axe longitudinal du support. A cet effet, l'âme et/ou au moins une des membrures présentent au moins dans une zone d'extrémité du support au moins un évidement qui est rempli d'une matière de remplissage possédant des propriétés d'absorption des chocs. L'invention concerne également un procédé de production d'un tel support de coffrage.
