Abstract

The utility model relates to a sound absorbing, thermal keeping and heat insulating waterproof pressure colored slab roof which is composed of a pressure colored slab (1) of a waterproof layer, an adhesive aluminium foil glass cotton felt (2) of a thermal keeping and heat insulating layer, fibre glass cloth (3) of a protective layer, and a pressure colored slab (4). The utility model is characterized in that a hole is punched on the pressure colored slab (4) to cause sound in a room to enter the adhesive aluminium foil glass cotton felt (2) of a thermal keeping and heat insulating layer and to be absorbed by the adhesive aluminium foil glass cotton felt (2) of a thermal keeping and heat insulating layer via the hole on the pressure colored slab (4). The utility model has the characteristics of great sound absorbing coefficient and good effect on absorbing sound. The utility model is suitable to roof buildings, such as gymnasiums, air ports, textile mills and cold processing workshops.

Description

Sound absorption, heat preservation, heat insulation, and waterproof pressed color plate roof.

The utility model relates to a sound-absorbing pressure-type color board roof.

Existing profiled color plate roofs are mainly composite profiled color plate roofs. Figure 1 is a cross-sectional view of an existing profiled color plate roof. Composed of cotton felt ② and protective laminated color board ③. From its structural point of view, although this kind of composite pressed color plate roof has the functions of waterproof, heat preservation and heat insulation, it cannot absorb sound, which is a major defect of it. If this kind of pressed color plate roof is used in the gymnasium, the echo is very loud, and indoor speech cannot be heard clearly; if this kind of pressed color plate roof is used in the textile cold processing workshop, the indoor noise exceeds the standard, which will damage the health of workers. The non-sound absorption of this type of pressed color board roof is caused by the small sound absorption coefficient of the protective laminated color board. Its sound absorption coefficient is α = 0.03, and the sound cannot enter. The space is large and high, and the reflected sound delay time is long, so the indoor sound absorption effect is poor. In order to improve the indoor acoustic environment, it is often necessary to spend huge sums of money on sound-absorbing treatment, such as hanging a sound-absorbing flat roof or sound-absorbing body under the roof to absorb part of the sound. Although the indoor noise is reduced like this, the construction cost is greatly increased, which also affects the indoor appearance.

The purpose of this utility model is to provide a new type of pressure-shaped color plate roof, which has the characteristics of sound absorption, heat preservation, heat insulation and waterproof, improves the sound absorption effect, reduces the cost of sound absorption, and maintains a beautiful structural shape.

The utility model is composed of a waterproof laminated color plate, a thermal insulation layer pasted with aluminum foil glass wool felt, a protective layer of fiberglass cloth and a pressed color plate with holes, and is characterized in that the protective laminated color plate is perforated, and Fiber glass cloth is placed between the perforated color plate and the aluminum foil glass wool felt. It is characterized in that the number of perforations on the pressed color plate is more than two. It is characterized in that the diameter of the hole perforated on the pressed color plate is more than 0.1 mm. It is characterized in that the shape of the perforated holes on the type color plate is any one of circle, ellipse, rectangle, square, rhombus and triangle, and the combined shapes among them. The sound absorption principle of the profiled color plate roof is to allow the indoor sound to enter and be absorbed by the aluminum foil glass wool felt through the holes on the profiled color plate along with the air. The sound absorption number of this kind of pressed color plate roof is relatively large, and the sound absorption effect is good. The sound absorption coefficient is detailed in the table below: frequency f 125Hz 250Hz 500Hz 1000Hz 2000Hz 4000Hz Sound absorption coefficient α 0.70 0.88 0.90 0.80 0.70 0.68

As can be seen from the table, the utility model is a pressed color board roof with strong sound absorption function. Its advantages not only have a good sound absorption effect, but also have a simple structure, better heat preservation and heat insulation performance, and are a low-cost and high-effect building material.

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

The utility model is composed of a waterproof laminated color plate ①, a thermal insulation layer pasted with aluminum foil glass wool felt ②, a protective layer of glass fiber cloth ③ and a pressed color plate ④, and is characterized in that the protective laminated color plate ④ is implemented Perforated, the indoor sound is absorbed by the air through the hole on the pressure-shaped color plate ④ through the fiber cloth glass cloth ③ into the heat preservation and heat insulation layer pasted with aluminum foil glass wool felt ②. It is characterized in that the number of perforations on the pressed color plate ④ is more than two. It is characterized in that the diameter of the perforated holes on the pressed color plate ④ is more than 0.1mm. It is characterized in that the shape of the perforated holes on the pressed color plate ④ is any one of circle, ellipse, rectangle, square, rhombus, triangle or a combination of them. As shown in the figure, the heat preservation and heat insulation layer is pasted with aluminum foil glass wool felt ② Mineral wool felt can be used instead of glass wool felt.
