Plastic pallet with stiffeners sheathed and associated method for manufacturing

摘要

Plastic pallet, comprising: an upper platform (12) consists of a plastic having a first melting point; a number of first connecting elements projecting downwardly from said upper platform (12), each first connecting element an outer tubular member (40) molded as part of the corresponding upper platform (12); a lower platform (14) is made of plastic having the first melting point; a number of second connecting elements projecting upwardly from said bottom plate (14), each second joining an inner tubular member (42) molded as part of the corresponding bottom plate (14); including at least one of said upper and lower platforms (12, 14) a series of channels (92 ', 102') between the upper and lower surfaces thereof; a series of rods of sheathed reinforcement (80 ') in the series of channels (92', 102 '), each reinforcing rod clad (80') a reinforcing rod (82) having opposite ends and side surfaces thereof, and a tubular element (84 ') enclosing the side surfaces of said reinforcing rib (82'), there being relative movement between the inner surfaces of said tubular element (84 ') and the side surfaces of said rebar (82) when said reinforcing rod (82) is tensioned, said tubular element (84 ') comprising a plastic having a second melting point higher than the first melting point temperature; and receiving the inner tubular member (42) of said plurality of second connectors outer tubular elements (40) of said plurality of first connecting elements to define a plurality of support blocks connecting said upper and lower platforms (12, 14).
