Description

一种通风隔声的副框型材
技术领域
本发明属于噪声治理领域,具体涉及一种通风隔声的副框型材。
背景技术
随着城市和交通的不断发展,城市人口的不断增加,住宅、道路和机场等场所的高噪声距离不断缩小,导致人们长期生活在一个充满噪音的环境中。目前常采用的隔声设施主要为隔声门窗,这种隔声门窗要实现隔声的效果,必须进行关窗隔声,关窗后人们就长期处于封闭的环境中,严重影响到人们的身体健康;并且,影响隔声门窗的效果之一就是门窗与安装墙体的密封性能,对于无副框安装后出现的安装缝渗水现象也时有发生,同时也因土建洞口的误差造成安装缝隙的不均匀,以及同种规格洞口尺寸偏差较大,给安装质量及施工进度也带来较大的影响。
现有的隔声门窗在玻璃上安装窗式通风器后,虽然能够达到一定的通风效果,但如果通风器本身的尺寸太小,就无法达到标准的通风要求;如果采用双层隔声门窗,其漏声面积就会增大,影响到隔声性能,同时也会减小门窗的采光面积,安装槽口接缝处的密封性也较差,生产成本高,隔声效果差。
发明内容
针对上述不足,本发明提供一种易于安装,并且通风性能和密封性能均较好的通风隔声副框型材。
本发明是通过这样的技术方案来实现的:
一种通风隔声的副框型材,包括部分预埋在上墙体中的通风框以及预埋在下墙体中的预埋框,其中,通风框与预埋框固定连接形成洞口框架,门窗便可安装于此洞口框架内,从而提高其密封性和通风性能。
所述通风框包括预埋在上墙体中的主框和固定连接在主框下方的副框,主框和副框上安装扣盖,从而将主框和副框紧紧固定在一起,并且将主框预埋在上墙体中,以形成牢固的通风框结构。
所述主框和副框上均设置有C形槽,扣盖上方为一U形槽,该U形槽与C形槽卡接,扣盖下方为倒勾结构,扣盖中部的弧度所形成的回弹力将扣盖卡于主框和副框上。
所述扣盖为双层结构,其下方安装进风开关,从而控制好室内的进风量。
所述主框与副框通过阻尼隔热条连接,从而提高隔声阻尼和隔热的性能。
所述主框和/或副框的内部填充吸声材料,该吸声材料可为吸声棉或其他吸声材质,该主框和/或副框与吸声材料一起形成隔声单元,以进一步提高整个型材的隔声性能。
所述阻尼隔热条为尼龙材质。
所述通风框与预埋框之间为螺钉和/或角码撞角连接,以提高整个副框型材的强度。
所述通风框内开孔形成通风单元,并在该单元中配装动力风扇、过滤网及吸声材料,动力风扇将室外的新鲜空气强制鼓入室内,过滤网可有效防止蚊虫或其他异物进入室内,装配吸声材料的通风单元形成消声通道,消除来自室外以及动力风扇工作时的噪音。这种通风单元可在不拆除通风框的情况下在室内安装,其安装和维护均十分方便、快捷,无需专业培训即可完成,适用性较广。
可根据需要,所述洞口框架并列设置,两者之前采用连接框连接形成双层通风隔声窗。
由于采用了上述结构,本发明的有益效果如下:
(1)       采用预埋式的通风框和预埋框组合结构,有效提高了整个副框型材与安装墙体的密封性,有效避免了现有通风窗安装时带来的缝隙及渗水问题,并且安装十分方便;该副框型材结构与通风单元有机结合,克服了现有双层通风隔声窗占用空间较大以及成本高效率低的缺陷,即使用单层的此类副框型材结构也可保证其通风性和密封性达到要求;该副框型材可采用铝合金挤出成型,生产较为简单,并且能够适应现有塑钢、铝合金、断桥铝合金、铝木复合等结构门窗的安装要求;与现有的通风器相比,该副框型材结构的安装和维护工作均得到了简化,通用性强。
(2)       采用扣盖将主框与副框有机的连接方式,进一步保证了副框型材安装时的稳固性,大大提高门窗的安装效率,减小材料损耗,节约生产成本。
(3)       更进一步的是,上述主框结构内可开孔形成通风单元,该通风单元内可装配动力风扇,以将室外的新鲜空气强制鼓入室内,增加室内空气的流动性;并且,主框内可填充吸声材料和过滤网,以进一步提高其隔声性能及空气质量。
(4)       该副框型材结构安装于玻璃上时,其不会占据玻璃的安装位置,更不会影响到原窗的采光面积。
(5)       该副框型材结构之间可采用连接框连接,形成双层结构,在通风状态良好的情况下增加门窗的隔声量,结构简单,安装方便。

具体实施方式
为了更加清楚地理解本发明的目的、技术方案及有益效果,下面结合附图对本发明做进一步的说明,但并不将本发明的保护范围限定在以下实施例中。
实施例1,如图1所示, 一种通风隔声的副框型材,包括部分预埋在上墙体1中的通风框2以及预埋在下墙体3中的预埋框4,其中,通风框2与预埋框4固定连接形成洞口框架;所述通风框2包括预埋在上墙体1中的主框5和固定连接在主框5下方的副框6,主框5和副框6上安装扣盖7;所述主框5和副框6上均设置有C形槽,扣盖7上方为一U形槽,该U形槽与C形槽卡接,扣盖7下方为倒勾结构,扣盖7中部的弧度所形成的回弹力将扣盖7卡于主框5和副框6上;所述扣盖7为双层结构,其下方安装过滤网以及进风开关;所述主框5与副框6通过阻尼隔热条8连接;所述主框5和/或副框6的内部填充吸声材料;所述阻尼隔热条8为尼龙材质;所述通风框2与预埋框4之间为螺钉和/或角码撞角连接;所述通风框2内开孔形成通风单元10,并在该单元中配装动力风扇9、过滤网12及吸声材料,新鲜空气的流向如图1中的箭头所示。
实施例2:如图2所示,与实施例1不同的是,本案采用双层结构,即在实施例1的基础上,洞口框架并列设置,两者之前采用连接框13连接形成双层副框型,新鲜空气的流向如图2中的箭头所示。
无论是实施例1还是实施例2,安装时,均先将主框5、副框6、扣盖7和阻尼隔热条8组合为通风框2,再在其内部铣出通风孔,安装动力风扇9以及吸声材料,然后再与预埋框4组合为洞口框架,在土建进行抹灰或湿作业完成之前,将此洞口框架安装在墙体里,待土建抹灰及湿作业完成后,只露出部分通风框2,,其余部分作为预埋部分埋到墙体里,门窗即安装在预埋部分上面,门窗上方与通风框2连接,这样便将门窗与副框型材结构有机的结合在一起,形成了通风性和密封性均较好的通风隔声门窗。
需要说明的是,本发明不限于上述两种实施方式,凡在本发明的精神和原则之内所作的任何修改、等同替换及改进等,均应包含在本发明的保护范围之内。
