Description

Fire-resistant building roof corrugated board

The new model relates to a building material, especially a fire-resistant building roof corrugated board.

Referring to Figure 1, an existing fire-resistant roof corrugated board 9 is suitable for locking multiple C-shaped steels 8 on the roof with multiple screws 7 (due to the angle of view, only one screw 7 and one C-shaped steel are shown in Figure 1 8) It includes an upper layer 91 in a continuous concave and convex shape, a lower layer 92 spaced apart from the upper layer 91, and a refractory layer 93 filled between the upper layer 91 and the lower layer 92 and made of rock wool. Because the safe use temperature of rock wool is about 600°C to 700°C, it does not support combustion or spontaneous combustion, and because of its high structural strength, it is suitable to be fastened to the C-shaped steel 8 with the screws 7 and can support maintenance Stepping on by personnel is therefore often used as the material of the refractory layer 93. However, when the fire breaks out for a period of time and enters the growth period, the temperature of the fire site can reach above 800℃, and it can reach 1200℃ in the heyday. Therefore, the existing fire-resistant roof corrugated board can only withstand the initial temperature of the fire. After a period of time, the fire resistance performance of the refractory layer 93 is obviously insufficient.

At present, it is known that ceramic wool with better fire resistance can withstand high temperatures from 1300°C to 1400°C, which can effectively extend the escape time. However, compared with rock wool, ceramic wool has a looser structure and weaker structural strength. If it is used as the material of the refractory layer 93, the refractory layer 93 will be difficult to support the locking force of the screws 7 and cause The upper layer 91 is recessed toward the lower layer 92, and the refractory layer 93 will hardly support the stepping of maintenance personnel. Therefore, it is necessary to find a solution.

Therefore, the purpose of the present invention is to provide a fire-resistant building roof corrugated board that can improve the fire-resistant performance and has structural strength.

Therefore, the new type of fire-resistant building roof corrugated board includes a base layer, a top layer spaced from the base layer and cooperated with the base layer to define an inner space, and a filling unit filled in the inner space. The filling unit includes a plurality of fireproof materials arranged at intervals, and a plurality of heat-insulating materials arranged alternately with the fire-proof materials and having a structural strength greater than the fire-proof materials, the fire-resistance of the fire-proof materials is greater than the heat-insulating materials, and The volume occupied in the inner space is larger than the heat insulating materials, so as to improve the overall fire resistance of the filling unit.

The effect of the present invention is to arrange the fireproof materials with stronger fire resistance and the heat insulating materials with stronger structural strength in a staggered manner, and use a relatively large number of fireproof materials to make the filling unit, in addition to improving The fire resistance of the filling unit improves the temperature resistance of the filling unit, while maintaining a certain structural strength of the filling unit, which helps prevent the top layer and the filling unit from deforming.
