Detailed Description
The present invention and its advantageous technical effects are further described in detail below with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 2, the steel shell composite building board of the present invention includes a non-metal board 81 as a board main body, and a steel sheet 83 as a board main body reinforcing composite board, wherein the steel sheet 83 is compounded on an outer surface of the non-metal board 81; the method is characterized in that: the steel sheet 83 has a plurality of hexagonal holes 84 according to honeycomb arrangement to the punching press of one side outwards, steel sheet 83 all is equipped with the triangle side tooth 85 of perpendicular steel sheet 83 one side inwards on the edge of hexagonal hole 84 below one side inwards, every limit of hexagonal hole 84 corresponds a slice of triangle side tooth 85, when this triangle side tooth 85 is by steel sheet 83 punching press hexagonal hole 84 downwards, divide the natural turn-ups of edge splitting along the diagonal by hexagonal hole 84 central point and form, inside each triangle side tooth 85 all pressed in nonmetal panel 81 downwards, steel sheet 83 closely compounds on nonmetal panel 81 through each triangle side tooth 85. The thickness of the non-metallic plate 81 is much greater than the thickness of the steel sheet 83.
Referring to fig. 1, the hexagonal holes 84 preferably have a total area of 35% to 45% of the total area of the entire steel sheet 83. That is, the open porosity of the steel sheet 83 is 35% to 45%, and more preferably 40%. The hexagonal holes are formed in a honeycomb hole forming mode, so that the anti-pulling force between the steel sheet 83 and the non-metal plate 81 is multiplied, all parts of the steel sheet 83 are stressed uniformly, the weak point of stress damage is avoided to the maximum extent, and the anti-pulling strength of the steel sheet 83 is greatly improved.

In addition, the non-metal plate 81 is a cement plate or a calcium silicate plate as required. The non-metal plate 81 may also be a PVC plate or a wood wool plate.
The process for manufacturing the steel shell composite building board comprises the following steps of pressing all the triangular side teeth 85 on the steel sheet 83 downwards into the non-metal board 81, and tightly compounding the steel sheet 83 on the non-metal board 81 through all the triangular side teeth 85. Taking a cement composite wallboard as an example, placing a punched hexagonal steel sheet 83 on the surface of a cement board in a shaping stage; and then the triangular side teeth 85 formed by punching and shearing hexagonal holes 84 through the steel sheet 83 are fully combined and wrapped with the cement board, and a composite structure is formed after maintenance is finished. Due to the clamping of the steel sheet 83, the integral bending resistance and shearing resistance of the steel shell composite building board are greatly enhanced, and the elastic modulus is larger; the whole thickness is thinner and the self weight is lighter.
The steel shell composite building board of the utility model has a plurality of application modes, for example, after the steel shell composite building board is installed on site, the steel shell composite building board can be used as a non-dismantling template of a common floor slab; the method can also refer to the common method of prefabricating the laminated slab and the steel bar truss floor bearing plate, and the steel bars and the poured cement are paved on the steel shell composite building board to form the prefabricated floor slab with the integral structure.
