Abstract
The utility model provides a suspended absorber which comprises an equilateral angle profile framework, a polyester fiber sound absorbing plate and expanded perlite particles. The equilateral angle profile framework serves as the edge of the suspended absorber, and is cut and welded to form the edge framework of the suspended absorber; and a hoisting screw hole is formed at an upper top point of the upper part of the suspended absorber. The polyester fiber sound absorbing plate serves as a panel of the suspended absorber. The suspended absorber can form different structures, and the surfaces can be spliced to form various patterns, thus meeting the requirements on the coordination of decoration of a high-end hall. The expanded perlite particles are filled into the suspended absorber formed by the polyester fiber sound absorbing plates, therefore, the purpose of sound absorption under a full range can be achieved. The suspended absorber has the advantages of low contamination factor, stability, ageing resistance, fire resistance, and convenience and simplicity in construction technology.
Description
Technical field
The utility model relates to a kind of building acoustics technology, especially can reduce room noise or improve the sound absorbing member of indoor tone quality.
Background technology
Suspended absorber is that a kind of dispersion hangs on architectural space top, in order to reduce room noise or to improve the sound absorbing member of indoor tone quality.Suspended absorber is compared with the sound absorption material on the chamber internal surface, and under same projected area, suspended absorber has higher sound absorption efficiency.This is because suspended absorber has bigger effective sound absorption area (the last end face, bottom surface and the side that comprise suspended absorber); In addition, because sound wave repeatedly reflection between end face on the sound absorber and building end face, thereby repeatedly absorbed, absorption is increased, improved sound absorption efficiency.Usually the most remarkable with the raising of middle and high frequency range sound absorption efficiency.Suspended absorber has that materials are few, in light weight, the characteristics of reduced investment, sound absorption efficiency height, flexible arrangement, easy construction.Suspended absorber requires and sound source characteristic according to the use character of building, area, floor height, form of structure, decoration, and multiple shapes such as tabular, square shape, bar shape, coniform and sphere-like can be arranged.Wherein tabular structure is the simplest, uses the most general.The suspended absorber scope of application: the heavy construction halls such as sports palace, grand theater, dancing hall; In order to keep the architectural style of itself; Can reach again simultaneously and build designing requirement, need the usage space sound absorber, suspended absorber also is applicable to the noise reduction of industrial premises etc.
At present, the set-up mode of common suspended absorber has: 1, reached by sound absorption filler (super glass wool outsourcing glass fabric) and constituted by skeleton, perforation protection slab; 2, use high-density fiber cotton, periphery is through the cure process moulding, and acoustextile is laid on the surface.But all have defective separately: 1, use the surface decoration effect of perforation protection slab suspended absorber relatively poor, environmental suitability is relatively poor, more uses at industrial premises.2, use high-density fiber cotton, moulding is limited to, the acoustextile that the surface is laid, if suspended absorber has big plane down, after a period of time, acoustextile can produce the tenesmus phenomenon.
The polyester fiber acoustical board is high except sound absorption coefficient, and outside the wide promptly excellent acoustical behavior of sound absorption frequency, it is moderate also to have thickness; Be prone to the cutting processing moulding; Good physical and mechanical property, light weight, being hit can not produce fragment after destroying or fall, and can curve curve form.The release and the fireproof performance of harmful substances all comply with the national standard requirements.The polyester fiber acoustical board has multiple color and texture, can be combined into various patterns, can pattern be duplicated on the polyester fiber acoustical board through computer.Expanded perlite granule is a porous absorption material; In light weight, acoustically effective is good, it does not exist glass fibre cotton, mineral wool, rock wool etc. to the harm of the harm of operator's respiratory system, health and as abandon after can not degrade and cause worry the harm of environment; It is low to possess pollution coefficient; Stablize characteristics such as anti-aging, fire prevention, environmental protection, simultaneously, have cheap advantage.
Summary of the invention
The utility model solves the technical scheme that its technical problem adopted: a kind of suspended absorber is made up of equilateral angle section framework, polyester fiber acoustical board, expanded perlite granule.Equilateral angle section is folded by galvanized steel plain sheet, and equilateral angle section is welded into suspended absorber seamed edge framework as the seamed edge of suspended absorber, and the upper vertex on the top of suspended absorber is provided with the lifting screw, the convenient installation.The upper and lower side corner cut of the angle of equilateral angle section, section bar is confirmed according to set shape moulding.The polyester fiber acoustical board is as the panel of suspended absorber, and the polyester fiber acoustical board sticks on outside the suspended absorber seamed edge, and the edge bevelling 45 deburring of polyester fiber acoustical board makes seam more elegant in appearance.The polyester fiber acoustical board has good physical and mechanical property, and suspended absorber can constitute the form of structure of different shaping, satisfies the sound source characteristic requirement of the hall.The multiple color and the texture of polyester fiber acoustical board can be combined into various patterns, can pattern be duplicated on the polyester fiber acoustical board through computer, satisfy the requirement of decorating with the high-grade hall, good decorating effect.
The sound absorption characteristics of polyester fiber acoustical board and other porous materials are similar, and sound absorption coefficient increases with the raising of frequency, and the sound absorption coefficient of high frequency is higher, and the suspended absorber that it constitutes can improve the sound absorbing capabilities of material greatly.It is inner that expanded perlite granule is filled in the formed suspended absorber of polyester fiber acoustical board, can increase suspended absorber in, low-frequency noise absorbs, and reaches the purpose of full-frequency sound absorption.If in the hall, low-frequency noise absorbs and be met, also can not load expanded perlite granule in the suspended absorber.
The beneficial effect of the utility model is, can reach the purpose of full-frequency sound absorption, suspended absorber can satisfy different shaping structural requirement, good decorating effect, possess pollution coefficient low, stablize anti-aging, fire prevention, characteristics that construction technology is easy.
