Abstract
The utility model belongs to a house with a steel structure, particularly a roof for the use of indoor sound absorption. The utility model is characterized in that the lower surface of a profiled sheet with a colored coating is connected with a glass wool layer, and the lower surface of the glass wool layer is connected with a porous sound absorbing plate. The upper layer of the glass wool is heat insulating glass wool, and the lower layer of the glass wool layer is sound absorbing centrifugal glass wool. The porous sound absorbing plate is a porous profiled sheet with a colored coating, and the punching rate of the porous profiled sheet with the colored coating is selected to be within the range of 6%-15%. A glass fiber cloth is clamped between the glass wool layer and the porous sound absorbing plate. The thickness of the sound absorbing centrifugal glass wool layer is selected to be within 30 mm-120 mm. The roof for the use of indoor sound absorption has the advantages of heat insulation, sound absorption, time saving, labor saving, material saving, low building cost and high work efficiency.
Description
Affiliated technical field: the utility model belongs to a kind of steel house, particularly about a kind of roofing that satisfies indoor sound-absorbing purposes.
Background technology: original steel house roofing is only noted insulation, and the roofing that does not have specialized designs to have the sound-absorbing purposes when needing sound-absorption requirement, is made the sound-absorbing perforation plate when indoor more in addition, promptly takes a lot of work, requires great effort, again waste material.
Summary of the invention: the purpose of this utility model is, a kind of roofing that satisfies indoor sound-absorbing purposes is provided, but it not only can be incubated but also sound-absorbing, save time, saving of labor, material-saving, reduced building costs, improved work efficiency.
The technical solution of the utility model is: design a kind of roofing that satisfies indoor sound-absorbing purposes, it is characterized in that: be connected with the glass wool layer below the coloured coating profiled sheet, be connected with the porous sound absorbing plate below the glass wool layer.
Described glass wool layer upper strata is the insulation glass wool, and lower floor is the sound-absorbing centrifugally glass-wool.
Described porous sound absorbing plate is a porous color coating profiled sheet.
The perforated percentage of described porous color coating profiled sheet is chosen in 6%-15%.
Between glass wool layer and porous sound absorbing plate, accompany the glass fiber layer of cloth.
The thickness of described sound-absorbing centrifugally glass-wool layer is chosen in 30mm-120mm.
Characteristics of the present utility model are: owing to be connected with the glass wool layer below the coloured coating profiled sheet, glass wool layer upper strata is the insulation glass wool, and lower floor is the sound-absorbing centrifugally glass-wool, is connected with the porous sound absorbing plate below the glass wool layer.The porous sound absorbing plate can be a porous color coating profiled sheet, and it is sound-absorbing but also play a supportive role not only.So it has reduced building costs, aspect material, this structure has not only been saved in a large number and be the required channel steel structure material of fixed support damping material in whole roof structure, and has saved the damping material and the roofing heat insulating material of part.Aspect construction: simplified construction sequence, improved construction speed, the construction and installation expense that corresponding saving is many.The utility model not only improves and has brought into play the indoor sound-absorbing effect and the effect of roof structure effectively, and has also improved the heat insulation and preservation effect of double-deck roofing simultaneously.This roof structure that satisfies indoor sound-absorbing purposes is more conducive to represent indoor decorative artistic effect.
The utility model is described in further detail below in conjunction with executing example figure.
Description of drawings: accompanying drawing 1 is an embodiment steel work roofing cut-away view.
Among the figure: 1, coloured coating profiled sheet; 2, insulation glass wool; 3, sound-absorbing centrifugally glass-wool; 4, glass wool cloth; 5, porous color coating profiled sheet.
The specific embodiment: below coloured coating profiled sheet 1, be connected with thickness 50m insulation glass wool 2 as shown in Figure 1 in turn, be connected with the thick sound-absorbing centrifugally glass-wool 3 of 100mm below the insulation glass wool 2, it also can be described as the super glass wool seat, below sound-absorbing centrifugally glass-wool 3, be covered with glass wool cloth 4, can prevent that glass wool from falling slag.The bottom is a porous color coating profiled sheet 5, it not only can attract sound but also plays a supportive role, its perforated percentage is 9%, the aperture is 5mm, pitch-row is 14.5mm, this roofing meets acoustical technology requirements such as public building such as sports palace, cinema, marquis's machine hall fully, also meets the indoor sound-absorption requirement of commercial building such as market, supermarket, sales exhibition hall etc. and industrial premises.
