在公共建筑中,门窗数量多,开关频繁,需要很好处理合页片之间的接触问题,否则会造成大量的金属磨擦噪声,影响建筑物的声响效果。北京市合页厂和北京市建筑设计院针对这个问题,制造了一种无声合页,在北京饭店新楼上首次应用,效果良 In public buildings, there are a large number of doors and windows, frequent switching, and it is necessary to deal with the contact problems between the hinge plates. Otherwise, a large amount of metal friction noise will be caused and the sound effects of the buildings will be affected. The hinged factory in Beijing and the Beijing Architectural Design Institute have created a silent hinge for this issue. It has been applied for the first time in the new Beijing Hotel building.
