修建物的一次噪音和二次噪音的区别
一次噪音:指的是由声源直接爆发并撒播到吸收点的声音,是噪音的原始发声状态。好比修建外部的交通噪声,像汽车行驶时的发念头声、轮胎与地面的摩擦声,以及修建内部的职员运动声、装备运行的直接发声等,如空调外机运行时发出的声音,都属于一次噪音。 二次噪音:是一次噪音引起的次生噪音。当一次噪音的振动能量转达到修建结构(如墙体、楼板等)后,使修建结构爆发振动,这种振动再向周围空气辐射出的声音就是二次噪音。例如,周围工厂机械运转爆发的振动通过地面和修建基础传至修建结构,引发结构振动从而爆发的噪音就属于二次噪音。

你能忍受无休止的噪声和振动吗?修建物的振动与二次辐射噪声限值是几多?各方主体会有什么样的考量呢?
一、适用标准及区域分类 依据?JGJ/T 170 - 2009?标准,修建区域分为五类: ?0?类和?1?类:疗养区、高级宾馆区、文教区及机关、事业单位集中区域,以及住宅为主的私人区域,对情形振动噪声要求较高。 ?2?类:栖身、商业与工业混淆区,妄想商业区。 ?3?类和?4?类:工业区或交通干线两侧区域。

日本隔震修建的抗震卓越体现:地动视察纪录下的稳固防地
在地动频发的日本,隔震修建已成为守护生命与工业清静的要害力量。自 1995 年阪神地动的沉痛教训后,隔震手艺在这片土地上蓬勃生长,现在,数目已超 5000 栋,若将独户住宅纳入统计,更是突破 10000 栋之多。这些修建类型富厚多样,办公楼、公寓、医院及独户住宅等都普遍应用了隔震手艺,工程师们巧妙组合种种隔震装置,像是橡胶支座、滑动支座、滚轴支座、滞回阻尼器、油压阻尼器等,犹如为修建全心打造了一套结实的抗震铠甲,力争在地动来暂时将灾难影响降至最低。

Company Profile:Introduction to well-known seismic isolation company in China
Seismic isolation and Shock absorption(Energy dissipation) technology is one of the most important innovation technologies in the field of earthquake prevention and disaster prevention engineering in the last 50 years. It protects the building itself and the lives and property of the occupants more effectively by isolating or consuming seismic energy in a soft way. QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) is a full solution and full life-cycle service provider of seismic isolation and Shock absorption(Energy dissipation) technology. Founded in January 2010, SAFETYINSIDE Is a high-tech enterprise, technology demonstration center and academician Zhou Fulin workstation in the industry. In March 2019, SAFETYINSIDE was successfully listed in Shenzhen Stock Exchange A shares (stock code: SZ300767), and was selected into the Ministry of Industry and Information Technology's first batch of "little giant" enterprises list, becoming a national manufacturing "single champion" and service-oriented manufacturing demonstration enterprises. QuakeSafe Technologies Co., Ltd.

Looking forward to cooperating with you! Seismic base isolation, also known as base isolation,or base isolation system,is one of the most popular means of protecting a structure against earthquake forces.It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus protecting a building or non-building structure's integrity. Common seismic isolation devices for buildings include: seismic bearing / seismic isolator / quake isolator / rubber bearing /Liner natural rubber bearing / lead rubber bearing /high damping rubber bearing/laminated rubber isolation bearing /elastic sliding bearing / friction pendulum bearing...... Their abbreviations are: LNR/LRB/NRB/ESB/HDR/ESB/FPS/FPB......
