And decorative layers are fixed on the outer surfaces of the upper protective plate and the lower protective plate. The connecting mechanism comprises connecting bolts and connecting ropes, the connecting bolts are divided into an upper group and a lower group, the upper group and the lower group of the connecting bolts penetrate through the protective plate respectively and are inserted into the fireproof core layer, and the connecting ropes connect the upper group of the connecting bolts and the lower group of the connecting bolts mutually through the inner side ends of the connecting bolts.

Furthermore, the inner side ends of the upper and lower groups of connecting bolts are provided with openings, and the connecting ropes penetrate through the openings to connect the upper and lower groups of connecting bolts with each other.

Further, the outer top surface of connecting bolt with guard plate lateral surface parallel and level.

Preferably, the connecting rope is a fireproof fiber rope.

Preferably, the distance between the connecting bolts in each group is 4-6 mm.

Preferably, the connecting bolt is made of aluminum.

Preferably, the decorative layer is made of aluminum.

Preferably, the protection plate is made of a titanium alloy material.

Preferably, the fireproof core layer is made of a castable refractory material.

Compared with the prior art, the utility model discloses following beneficial effect has:

one, the utility model discloses in, use the titanium alloy material as the guard plate, the high strength that utilizes this material has greatly improved the anti bending performance of fire prevention composite sheet, and the titanium alloy has the advantage that the quality is light, the corrosion resistance is good equally moreover.

Two, the utility model discloses in, adopt the connecting bolt and connect the rope and carry out fixed connection with upper and lower two-layer guard plate, later pour refractory material between to the two-layer guard plate again, can avoid the glue in the traditional fire proof board to lose the phenomenon that each layer of panel that viscidity leads to drops because of high temperature. In addition, the connecting bolt adopts the aluminum material, and the coefficient of thermal expansion of aluminum material will be greater than the coefficient of thermal expansion of titanium alloy, consequently when being heated, aluminum material expansion rate will be greater than the coefficient of expansion of titanium alloy to can fix more firmly on the guard plate, the connecting rope then adopts fire prevention fiber rope, and intensity is high and fire behavior is outstanding.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, an a 2-grade titanium-aluminum fireproof composite board comprises an upper titanium alloy protection plate and a lower titanium alloy protection plate 1, wherein a fireproof core layer 2 is clamped between the two protection plates 1, and the two protection plates 1 are reinforced by a connecting mechanism. The outer surfaces of the upper and lower layers of protection plates 1 are both fixed with aluminum decoration layers 4. Coupling mechanism includes that aluminium connects tie 3 and connection rope 5, connects rope 5 to be the fire prevention fiber rope, connects tie 3 to divide into about two sets ofly, and upper and lower group connects tie 3 to pass respectively in protection plate 1 inserts the fire prevention sandwich layer 2 of constituteing by the refractory material of can building, and the interval that each group was connected tie 3 each other is 5mm, connects 3 outer top surfaces of tie and 1 lateral surface parallel and level of protection plate.
