Abstract
The utility model discloses a foamed aluminum inhales sound type tunnel fire prevention decorative board has characteristics such as fire-resistant limit height, light weight excellence, feature of environmental protection nature good, simple structure, construction convenience, can improve the decorative effect in the tunnel. The problems that the plate can fall off after long-term water absorption and the plate is burst and collapsed when a fire disaster happens are solved. Can be widely used for the fire protection of various tunnels. The utility model discloses a foamed aluminum inhales sound type tunnel fire prevention decorative board is because its special foamed aluminum obturator structure for panel can also inhale the sound, takes precautions against earthquakes on the basis of environmental protection fire prevention, has multiple functions.
Description
Technical Field
The utility model relates to a tunnel fire prevention field, concretely relates to foamed aluminum inhales sound type tunnel fire prevention decorative board.
Background
Tunnels are a common type of engineering in modern traffic systems. The inner walls of urban road tunnels and highways need to be decorated and fireproof. In order to improve the fire-resistant and decorative properties of the tunnel, it is a common method to install a fireproof plate on the lining of the tunnel. The tunnel fireproof plate is a fireproof plate which is fixed on the inner walls of a highway tunnel, a railway tunnel, a subway and an urban traffic tunnel and can improve the fire endurance of a tunnel structure. The disclosed patents are poor in sound-absorbing performance. At present, most of tunnel fireproof plates have the following defects:
1) the capacity is great. The existing tunnel fireproof plate has larger volume weight, and the fireproof plate is arranged on a tunnel lining body and has great potential safety hazard once falling off.
2) The installation is difficult. The conventional tunnel fireproof plate is large in weight, poor in flexibility and easy to damage during installation.
3) The water seepage of the tunnel is a worldwide problem which is not completely solved so far. The tunnel fire-proof plate is in the humid environment of the tunnel for a long time, the weight is increased after water absorption, the strength is reduced, and the fire-proof plate can fall off to become a potential safety hazard due to strong wind and vibration generated in the tunnel when a vehicle passes through the tunnel fire-proof plate.
4) The flame retardant property and the mechanical property of the tunnel fireproof plate cannot be well balanced, and the two properties are balanced.
5) The keel is required to be installed in the tunnel arch ring by adopting the fireproof plate for decoration, and the fireproof plates are installed on the keel one by one, so that the fireproof plate is safe compared with a ceramic tile, but the construction difficulty is high, the construction cost is high, and the possibility of breakage of the fireproof plate in use is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tunnel fire prevention decorative board that incombustibility is good, mechanical properties is good, the light, inhale sound, waterproof impervious, the construction is simple, decorative diversified, can effectively solve the problem in the background art.
The technical scheme of the utility model is that:
the utility model relates to a foamed aluminum inhales sound type tunnel fire prevention decorative board comprises obturator foamed aluminum panel unit, foamed aluminum panel can be according to the processing of tunnel geometric figure customization. The foamed aluminum plate and the tunnel lining body are connected by adopting an adhesive. And the periphery of the foamed aluminum plate is provided with a fixing piece. And sealing strips are arranged between gaps among the foamed aluminum plate units. The foamed aluminum plate can be made into different decorative patterns through an automatic paint spraying line according to programming so as to realize the decorative effect of the tunnel.
Further, the fixing piece is an expansion bolt.
Further, the sealing strip is a metal strip or a sealing glue.
The utility model has the advantages that:
1) the fire resistance limit is high. Foamed aluminum is the highest grade A-grade flame-retardant fireproof material. The structure remained intact by baking at 1000 ℃ for 1 hour. The heat conductivity coefficient is only 0.2-0.4W/(m.K), and the heat insulation performance is 100 times of that of aluminum.
2) The environmental protection is good. In case of fire, the tunnel fireproof material should not generate toxic gas so as to facilitate fire fighting. The smoke toxicity produced by the foamed aluminum plate of the utility model reaches (AQ-1) safety level. The production process has no "three wastes".
3) The installation is convenient. The size and radian of the foamed aluminum plate can be manufactured according to the requirement. The tunnel fireproof plate can be arranged according to the specific situation of the tunnel lining body.
4) Light weight and high strength. The volume weight of the foamed aluminum is only 0.2-1.0 g/cm3The safety is greatly improved. The strength is about 5 times that of steel with the same weight.
5) The defect of single color of the traditional fireproof coating is overcome, the product color is richer, the tension of a driver during driving can be greatly reduced, and the color is more striking.
6) Excellent sound insulation performance. The foamed aluminum is in a closed-cell form, the noise reduction coefficient NRC is 0.4-0.8, the closed-cell foamed aluminum can absorb more than 70% of sound, and meanwhile, the foamed aluminum is a few of sound-absorbing materials which are fireproof and do not reduce in performance in a humid environment.
7) Water and barrier resistance. Because the foamed aluminum is a metal material, the air bubbles in the foamed aluminum are closed-cell type, and the air holes are not communicated, the fireproof plate has excellent water resistance and impermeability compared with the traditional fireproof plate material.
