In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a cold rolled steel sheet, includes the steel deck, the impartial interval in both sides of steel deck is equipped with a plurality of openings, install first strengthening rib in the opening, be fixed with the titanium sheet layer jointly on a plurality of first strengthening ribs in the same horizontal plane, the relative one side on two titanium sheet layers is inconsistent with the both sides of steel deck respectively, the opposite side coating on titanium sheet layer has the bonderizing layer, the one side coating on bonderizing layer has the dope layer, and the relative one side on two titanium sheet layers all is equipped with a plurality of recesses, install the second strengthening rib in the recess, the upper end of second strengthening rib is fixed with the third strengthening rib, be equipped with the through-hole jointly on bonderizing layer and the titanium sheet layer, the third strengthening rib is located the through-hole.

Preferably, in order to improve the firmness of connection, the later period of time of being convenient for when the extrusion tie point is more firm, a plurality of first strengthening ribs and titanium plate layer integrated into one piece with the same side.

Preferably, in order to further improve the firmness of connection and well avoid the loosening condition through multi-point positioning, the third reinforcing ribs, the second reinforcing ribs and the steel plate layer are integrally formed.

Preferably, in order to facilitate production according to needs and improve the production efficiency and quality, the thickness of the steel plate layer is 1-6mm, the thickness of the titanium plate layer is 0.15-1mm, and the coating layer is a polyvinylidene fluoride finish paint layer.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the openings, the first reinforcing ribs, the grooves and the through holes are arranged, and the second reinforcing ribs and the third reinforcing ribs are arranged to correspond to each other, so that the steel plate layer and the titanium plate layer can be well connected and formed, the connection firmness of the steel plate layer and the titanium plate layer is ensured, the steel plate layer can deform during cold rolling, and the buckling and the connection firmness are well ensured;

2. by coating the phosphate coating and the coating layer, the subsequent operation is convenient, the corrosion prevention effect can be well achieved, and the service life of the steel plate is prolonged;

to sum up, the utility model discloses a set up corresponding strengthening rib, opening and recess to guarantee the fastness that steel deck and titanium sheet layer are connected, promote holistic stability, and through setting up rust-resistant and finish paint can increase of service life well, be convenient for follow-up use of processing.
