高层住宅建筑外栏杆构件噪声研究

Noise study of railing parts outside high-storey residence buildings

通过现场测试,并将测试结果进行噪声成因理论分析,对照国家规范标准提出理论处理原则并实施,即对产生噪声的主要声源采用刚性连接和附加材料以及在现有振动杆件两侧分别增加固定杆件的做法,提高横向强度,减少横向振幅及竖向振幅并提高整体稳定性,改造前后噪声检测数据有较大变化,效果十分明显,从测试数据分析得到,同样风力及户型,从经济性及施工角度考虑,采用刚性连接和附加材料并用,效果更理想。

Through solving the noise problem by an on-the-spot inspection and by a theoretical analysis of those causes of the noise, based on the national standard, some theoretical principles are put forward and are applied in this paper. Steel connection and additional materials are used and bars are fixed to the railings so that, horizontally, the railings are strengthened and the amplitude is reduced, whereas, the vertical amplitude is increased and the stability on the whole is improved. The noise statistics obtained vary greatly, which shows that under the same wind power, in the same house-size, the results are much better economically and constructionally.
