(2) the distribution intervals of the punched holes of the hollowed-out steel plates are too large, the hole opening rate of the punched holes is only 18%, the phenomenon of uneven stress is easy to occur due to the adoption of an array arrangement mode, so that the damage limit of the hollowed-out steel plates is lower, the stress in the contraction process of the plate main body is not reduced, and the stress is easy to generate bending deformation after the plate is maintained;

(3) the uplift resistance between the hollowed-out steel plate and the plate main body is not enough, so that stress on each part of the hollowed-out steel plate is not uniform enough, the weak point of stress damage can be generated under specific conditions, and hidden danger is generated due to the insufficient uplift resistance of the hollowed-out steel plate.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned defect that the fretwork steel sheet of current box hat composite sheet coincide superstructure exists because of the distribution that punches a hole, the utility model provides a better box hat that is used for box hat composite wall board of each item performance.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the utility model provides a steel-shelled for steel-shelled composite wall board, includes compound steel-shelled, characterized by: the composite steel shell is punched outwards to form a plurality of hexagonal holes, the adjacent hexagonal holes are arranged in a honeycomb form, the inner side of the composite steel shell is provided with triangular side teeth perpendicular to the inner side of the composite steel shell on the edge below the hexagonal holes, and each side of each hexagonal hole corresponds to one triangular side tooth.

Further, the total area of the hexagonal holes accounts for 35% -45% of the total area of the whole composite steel shell.

Further, the total area of the hexagonal holes accounts for 40% of the total area of the whole composite steel shell.

When the steel shell composite wallboard is used, the steel shell for the steel shell composite wallboard can be cut into a required shape at will in a factory, and the composite steel shell belongs to a metal piece easy to weld, so that building components with any span and any shape, such as a superposed floor system, a non-dismantling building template and the like, can be spliced by a welding process.

By last, for current prefabricated panel main part superimposed sheet and building carrier plate, the utility model discloses following advantage has:

for the aperture ratio of the array trompil of the steel shell composite sheet coincide superstructure of among the prior art adoption fretwork steel sheet only be 18%, the utility model discloses a change hexagonal hole trompil arrangement, increased the aperture ratio of compound box hat, under the same condition of compound box hat area, the aperture ratio has reached more than 40%, has also increased the area in the triangle limit tooth embedding nonmetal panel of compound box hat simultaneously to the grip of nonmetal panel to compound box hat has further been increased, has improved the destruction limit of the compound building board of box hat.

In addition, when the composite steel shell is used, the arrangement mode of the openings at the six sides is changed into honeycomb arrangement, so that the anti-pulling force between the composite steel shell and the non-metal plate is multiplied, all parts of the composite steel shell are stressed uniformly, the weak point of stress damage is avoided to the maximum extent, and the anti-pulling strength of the composite steel shell is greatly improved.

By last, for current prefabricated panel main part superimposed sheet and building carrier plate, the utility model discloses following advantage has: the aperture ratio of the composite steel shell is more scientific, the hexagonal apertures of the composite steel shell are more practical to distribute, the tensile strength of the composite steel shell is increased by the honeycomb aperture arrangement mode of the hexagonal apertures, and the anti-falling performance is high; due to the addition of the composite steel shell, the integral bending resistance and shearing resistance of the manufactured steel shell composite wallboard are greatly enhanced, and the elastic modulus is larger.

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. 1-5, the utility model discloses a steel casing for steel casing composite wall panel of preferred embodiment, including compound steel casing 3, compound steel casing 3 one side towards the outside is stamped has a plurality of hexagonal holes 4, arranges according to honeycomb formation between the adjacent hexagonal hole 4, and compound steel casing 3 one side all is equipped with perpendicular compound steel casing 3 triangle tooth 5 of one side inwards on the edge of hexagonal hole 4 below inwards, and every limit in hexagonal hole 4 corresponds a slice triangle tooth 5. The triangular side teeth 5 are formed by splitting and naturally flanging the center point of the hexagonal hole 4 along the diagonal line when the hexagonal hole 4 is punched downwards by the composite steel shell 3.
