The invention provides a shuttering member, which comprises an upper board, peripheral side panels, the upper board and the peripheral side panels encloses an open basin shape component, characterized a projected edge is arranged on the peripheral panel panels, the thickness of the projected edge is greater than the thickness of the peripheral panels, thus, when the shuttering member is applied to the roof construction, after the projected edges are pieced each other, construction shutterings or precast thin slabs can be substituted, the shuttering member also has the advantages of reducing building roof weight, lowered cost, furthermore, the shuttering members also have the advantages of high strength, large rigidity, furthermore, the shuttering member also has the advantages of simple construction, good deformation resistance, fine vibration resisting performance, easy manufacture, low cost. The shuttering members are adapted for the application of hollow building cover, room cover, wall, foundation slab and laced beam bridges of the cast-in-situs reinforcing steel concrete or prestressed reinforcement concrete, especially for hollow building covers with no beams or dense rib building covers.
