Panel for making a building construction and method of making such panel

Panel (10) for making a construction, in particular a building construction such as an upright wall, comprising a panel body (12) made from an insulating material manufactured from a plastic material preferably an expanded material such as expanded polystyrene, wherein it comprises projecting means (26, 28, 30) which extend from a face (16) of the panel perpendicularly with respect to the longitudinal face (16) of the panel, the panel has engaging and retaining means designed to exert a retaining action in the crossways direction, the engaging and retaining retaining means are on the free end (26e, 28e) of the projecting means (26, 28), the retaining means comprising a protuberance (32) having an end face (32c) and opposing side faces (32a, 32b) perpendicular to the end face (32c) and/or a recess (34) having a bottom face (34c) and opposite side faces (34a, 34b) perpendicular to the bottom face (34c).

Composite panel (100) for making a construction, in particular a building construction such as an upright wall, comprising a first and a second counteropposing panels where the panel body (12) is made from an insulating material manufactured from a plastic material preferably an expanded material such as expanded polystyrene, wherein at least one of the panels (10′, 10″) has projecting means (26, 28, 30) which extend from a corresponding face (16) of the panel and which are designed to hold the panel at a distance apart from the counteropposing panel, wherein the projecting means (26, 28, 30) rest directly against a counteropposing face of the other panel, wherein at least one of the first and second panels (10′, 10″) has panel engaging and retaining means which have the form of protuberances and/or recesses (32, 34) that engage with corresponding recesses and/or protuberances (34, 32) on the other panel, wherein engaging and retaining means are on the projecting means (26, 28) of the panel (10′, 10″), the protuberance (32) having an end face (32c) and opposing side faces (32a, 32b) perpendicular to the end face (32c) and the recess (34) having a bottom face (34c) and opposite side faces (34a, 34b) perpendicular to the bottom face (34c).
