Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to figures 1-4 of the drawings there is shown an embodiment of a novel fire-resistant roof panel according to the utility model,

the fire-resistant composite material comprises a frame 1, a structural layer 2 arranged on the upper end surface of the frame 1, a supporting layer 3 arranged on the lower end surface of the frame 1 and a fire-resistant layer 4 which is positioned in the frame 1 and is arranged between the structural layer 2 and the supporting layer 3; wherein the supporting layer 3 is formed by stacking a plurality of layers of supporting plates 31, and a plurality of small holes 32 are arrayed on the supporting plates 31; the positions of the small holes 32 of two adjacent support plates 31 are staggered.

The structural layer 2 adopts magnesium-aluminum-manganese alloy, and is prepared by adding manganese and magnesium components on the basis of common aluminum materials, and the produced aluminum alloy has better tensile strength, yield strength and elongation than the common aluminum materials. The tensile strength and yield strength of the aluminum alloy are doubled compared with those of common aluminum materials, and the oxidation corrosion resistance of the aluminum alloy is further enhanced, so that the aluminum alloy is called as rust-proof aluminum in the metal industry, and therefore, the aluminum-manganese-magnesium alloy has the characteristics of rust prevention and high strength and is wide in application.

The fireproof roof board of the device can be used for laying a house roof or a wall surface; the main function of the support layer 3 is thus the support of the roofing panel; in the device, the supporting plate 31 which divides the supporting layer 3 into a plurality of layers is overlapped and paved, and the small holes 32 are arranged on the supporting plate 31, so that the small holes 32 can be used for playing a certain role in sound absorption under the condition of ensuring the supporting strength, and the inside of a house is not interfered by external noise; when the acoustic wave is conducted into the aperture 32, the energy of the acoustic wave is spread over the inner wall of the aperture 32, at which time the energy of the acoustic wave portion is absorbed.

The number of the support layers 3 is at least two, and in the two support plates 31 after the superposition, the edge of the small hole 32 in the lower support plate 31 passes through the center point of the small hole 32 in the upper support plate 31.

The staggered arrangement of the positions of the holes 32 in different support plates 31 can enable the support plates 31 to form a step surface after superposition, so that the number of the sound wave reflecting surfaces can be increased, and the capacity of absorbing sound wave energy is increased; as shown in fig. 4, the sound absorbing effect of the support layer 3 is further improved.

A plurality of protruding strips 33 are uniformly arranged on the supporting plate 31, and the protruding height of the protruding strips 33 is 65mm; the protruding strip 33 is integrally formed with the support plate 31 and is stamped from a flat sheet material; the setting of protruding strip 33 in this device can change backup pad 31 wholly and be the bearing force direction, will originally vertical effort on backup pad 31 face, changes the uniformity of effort direction through the curved surface of protruding strip 33 to increase the anti deformability of backup pad 31.

The small holes 32 of the device are also arranged at the positions of the convex strips 33, compared with other plane positions, firstly the convex strips 33 increase the area of sound wave reflection, on the other hand, the small holes 32 positioned on the convex strips 33 incline in directions, a plurality of directions are provided for sound waves to enter the small holes, and the effect of absorbing sound waves of the roof board is further increased.

The support plates 31 are made of aluminum alloy, and a sound-absorbing blanket 34 made of glass floss is laid between two adjacent support plates 31.

Since the main function of the support plate 31 is to support, the effect of the improved support plate 31 for absorbing the vibration generated by the sound is not ideal, so that the sound-absorbing blanket 34 is placed between the two support plates 31, on the one hand, the whole support performance of the support plate 31 can be ensured, and on the other hand, the efficiency of absorbing the sound volume when the sound-absorbing blanket 34 is independently arranged is enhanced.

The sound-absorbing blanket 34 is provided with the same number of small holes 32 as the supporting plate 31 in an array, and the small holes 32 on the supporting plate 31 are staggered; the provision of apertures 32 in the sound-absorbing blanket 34 can further increase the efficiency of absorbing sound volume.
