Abstract
The invention discloses a brick masonry and a method for natural ventilation, noise elimination and noise insulation, and belong to the insulation (E04B) class of buildings. The invention overcomes the disadvantage that the prior soundproof window method realizes air ventilation through the energy consumption of a ventilation system when insulating noises through a sealed window. The brick masonry consists of five parts, namely a dissipative-resonant chamber component, an expansion chamber component, a bypass pipe component, an interference chamber component, and a buffer chamber component, wherein sound waves are parallelly transferred from an entrance of a dissipative-resonant chamber; firstly, partial sound energy is transformed into thermal energy by friction in pores of a porous conical cylinder wall and is consumed; then the sound waves enter an expansion chamber, and the change of the resistance is aroused during the sound propagation to produce reflection and interference phenomena of the sound waves due to the mutation of the cross section of a channel and the design of a bypass pipe (containing an interference chamber), thereby reducing sound energy radiated outward from the expansion chamber, achieving the aim of noise elimination, and ensuring that an isolation booth utilizing the brick masonry can achieve the effects of noise insulation and noise reduction; at the same time, the isolation booth built by the method is not a confined space, and an air current can circulate through pores in wall bodies built according to the masonry, thereby ensuring that the indoor environment formed by the wall bodies built by using the masonry can synchronously realize the functions of natural ventilation and no noise.
Description
(1) technical field: the present invention relates to a kind of can natural ventilation can the noise elimination again every the technology of making an uproar simultaneously, the noise that especially is suitable for overlooking building is eliminated, and belongs to isolated (E04B) class of building.
(2) background technology: the approaching noise elimination of existing and the present invention is every method for de-noising and device, its main defective is as follows: 1. the noise elimination of Cai Yonging mainly is by the sound proof window mode every method for de-noising, this mode can be eliminated the noise when the window air-tight state every making an uproar, but can not realize circulation of air simultaneously; As open the window and realize that natural ventilation just can not intercept noise.2. the ventilation system of isolation booth generally realizes the room ventilation ventilation by the blower fan consumed power, and vibration that its ventilating duct and blower fan cause and noise are difficult to eliminate, and form new noise source easily; The blower fan long-time running, power consumption is high and easily motor is damaged, and causes ventilation system normally to move for a long time.
