Description

一种用于建筑构件隔声性能检测的实验室
技术领域
本发明涉及噪声检测领域,尤其涉及一种用于建筑构件隔声性能检测的 实验室。
背景技术
对设备的隔声测试通常需要在搭建好的隔声实验中进行。隔声实验室由 声源室、接收室、控制室组成。隔声实验室测试房间包括两间相邻的混响室, 一间为声源室,另一间为接收室,两室之间设试件洞口,用以安装试件。为 了控制测试房间的背景噪声,抑制侧向传声,准确测量建筑材料及构件的空 气声隔声性能,隔声实验室采用“房中房”构造。声源室与接收室之间在结 构上完全脱开;声源室、接收室与原基础间设置隔振材料;实验室的新增外 墙,声源室、接收室的墙体、地面及顶选用高隔声性能的材料;测试房间的 门均采用双道隔声门,作成“声闸”,进一步提高门的隔声能力。
目前,国内建筑隔声实验室多数采取岩棉板、减震垫甚至是木块,将实 验室基础与地基隔离,减少因为刚性连接造成的共振,影响实验室背景噪声 的控制。这几种方式具有以下特点:1、岩棉板垫:放在实验室基础下,3-5 年之后粉化,失去了消声减震的功能,影响实验室背景噪声;2、木板垫:起 到一定的减震作用,但是固有频率较高,并不能把背景噪声控制在一个较低 的级别;3、减震垫:抗环境污染与抗温变化能力较弱,寿命较短。
发明内容
有鉴于此,为了解决现有的建筑隔声实验室检测效果不佳,且使用寿命 短的问题,本发明提供一种用于建筑构件隔声性能检测的实验室。
本发明的技术方案是这样实现的:
一种用于建筑构件隔声性能检测的实验室,包括顺序设置的门窗接收室、 发声室以及墙体接收室,所述门窗接收室与所述发声室之间设置有第一隔音 墙,所述发声室与所述墙体接收室内设置第二隔音墙;
所述门窗接收室的底部、所述发声室的底部、所述第一隔音墙的底部以 及所述第二隔音墙的底部均设置有隔振垫;
所述墙体接收室底部设置有减振器。
优选的,所述门窗接收室的底板、发声室的底板以及墙体接收室的底板 均设置有撞击声隔声垫层。
优选的,所述隔振垫采用Regupol Vibration 800型隔振垫。
优选的,每个所述隔振垫的规格为250*250*60mm。
优选的,所述减振器包括弹簧以及设置在弹簧两端的橡胶衬垫。
优选的,所述弹簧的外圈包套不锈钢液网丝。
有益效果:
本发明通过顺序设置门窗接收室、发声室以及墙体接收室,实现噪音的 检测,并且门窗接收室的底部、所述发声室的底部、所述第一隔音墙的底部 以及所述第二隔音墙的底部均设置有隔振垫,墙体接收室底部设置有减振器, 保证在检测过程中,具有较好的检测效果,并且采用隔振垫,大大增加了使 用寿命。
附图说明
图1为本发明用于建筑构件隔声性能检测的实验室的结构原理图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而 不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
如图1,本发明实施例提出了一种用于建筑构件隔声性能检测的实验 室,包括顺序设置的门窗接收室1、发声室2以及墙体接收室3,所述门窗 接收室1与所述发声室2之间设置有第一隔音墙4,所述发声室2与所述 墙体接收室3内设置第二隔音墙5;所述门窗接收室1、发声室2以及墙体 接收室3的底板均设置有撞击声隔声垫层6。
所述门窗接收室1的底部、所述发声室2的底部、所述第一隔音墙4 的底部以及所述第二隔音墙5的底部均设置有隔振垫7;
所述墙体接收室3底部设置有减振器8。
所述隔振垫7采用Regupol Vibration 800型隔振垫,本实施例中采 用,本实验室隔振垫7的布置数量是88个点位,每个的规格是 250*250*60mm。承载面积是0.25*0.25*88=5.5平方米,总荷载估计值是 300吨。单位荷载是0.55N/平方毫米。60mm厚度的RegupolVibration 800 型隔振垫,在0.55N/平方米荷载下的固有频率约为9Hz,低于设计要求的10Hz。
所述减振器8包括弹簧以及设置在弹簧两端的橡胶衬垫,均为钢质封 闭式结构,弹簧采用优质弹簧钢丝,制造时增加喷丸工艺,有效提高弹簧 使用强度和使用寿命,确保减震器使用年限30年以上。弹簧外圈包套不锈 钢液网丝作为阻尼材料,阻尼系数大,无老化期,免维护保养,特别适用 于隔音房、消声室的基础隔振。
