具体实施方式
本发明公开了一种变电站用保温吸隔声围护墙体，该装置通过由第一芯层、第二芯层和第四芯层组成的多层复合夹芯层才能实现的保温降噪功能，提升围护墙体的保温能力和降噪能力。
实施例
一种变电站用保温吸隔声围护墙体，如图1所示，包括多层复合夹芯层。多层复合夹芯层包括依次设置的第一芯层3、第二芯层4和第四芯层6，第一芯层3、第二芯层4和第四芯层6均为板形；所述第一芯层3和所述第四芯层6用于阻隔声音，所述第二芯层4用于保温和吸收声音。
第一芯层3和第二芯层4之间可以固定连接，这里，固定连接的方式不 作限定。第四芯层6和第二芯层4之间可以直接固定连接，也可以通过其他结构件固定连接，这里，固定连接的方式不作限定。
第一芯层3和第四芯层6的具体材质不做限制，可以实现增强多层复合夹芯层的刚度和面密度即可，第二芯层4的具体材质不做限制，可以实现吸收声音和保温的功能即可，本实施例中第一芯层3和第四芯层6可以选用纤维水泥板和石膏板之一，当选用纤维水泥板，纤维水泥板具有优良的防火绝缘和防潮性能、不易变形及翘曲，适用于变电站的围护；第二芯层4选用岩棉板和玻璃丝绵之一，当选用岩棉板，岩棉板因其导热系数小而具有良好的保温性能，使用不小于180mm厚的岩棉板可以使围护墙体的传热系数低于0.25W/(m 2·K)，适用于极寒地区的装配式建筑，同时岩棉板还具有化学稳定性强，不易腐烂，防火性能好的特点。第二芯层4的面积与第一芯层3的面积可以相等，这里，第二芯层4的面积是指第二芯层4与第一芯层3接触侧的面积，第一芯层3的面积是指第一芯层3与第二芯层4接触侧的面积。第二芯层4的面积和第四芯层6的面积可以相等，这里，第二芯层4的面积是指第二芯层4与第四芯层6接触侧的面积，第四芯层6的面积是指第四芯层6与第二芯层4接触侧的面积。其中，第一芯层3上不开设穿孔，用于增强多层复合夹芯层的隔声性能。第一芯层3和第四芯层6的厚度可以均不低于10mm。第二芯层4的厚度可以不低于180mm。第二芯层4可以具有弹性，第二芯层4通过弹性能够支撑第一芯层3和第四芯层6。
第四芯层6有三个作用：首先，将第四芯层6面向室内噪声设备，第四芯层6与岩棉板的组合是很好的吸声结构，对噪声有良好的吸声作用；第二，与第一芯层3相同，增强芯材的刚度和面密度，从而大大增强夹芯层墙体的隔声性能；第三，第四芯层6与第一芯层3形成了对称结构，使围护墙体重心稳定，便于安装。
多层复合夹芯层还可以包括第三芯层5，如图1所示，第四芯层6上开设有用于吸声的穿孔，穿孔的孔径可以为5mm-8mm、孔间距可以为15mm-20mm。第三芯层5安装于第二芯层4与第四芯层6之间，用于防止 第二芯层4从第四芯层6的穿孔外露。第三芯层5可以选用透声织物，作为一示例，透声织物可以选用无纺布和桑皮纸之一。在内面板2与岩棉板之间附一层透声织物可以防止岩棉纤维溢出。
变电站用保温吸隔声围护墙体还可以包括外面板1、内面板2和聚氨酯泡沫封边7，聚氨酯泡沫封边7设置为两个，两个聚氨酯泡沫封边7分别设置于多层复合夹芯层的相对两侧，外面板1依次包覆于两个聚氨酯泡沫封边7中的一个聚氨酯泡沫封边7、第一芯层3和两个聚氨酯泡沫封边7中的另一个聚氨酯泡沫封边7外侧，内面板2包覆于两个聚氨酯泡沫封边7中的一个聚氨酯泡沫封边7、第四芯层6和两个聚氨酯泡沫封边7中的另一个聚氨酯泡沫封边7外侧。两个聚氨酯泡沫封边7呈配合形状，可以与相邻的围护墙体配合连接。聚氨酯泡沫封边7与外面板1和内面板2均可以通过隐形钉连接。当然，聚氨酯泡沫封边7与外面板1和内面板2也可以通过其他方式连接。
作为一示例，两个所述聚氨酯泡沫封边7中的一个聚氨酯泡沫封边7具有凹陷部，两个所述聚氨酯泡沫封边7中的另一个聚氨酯泡沫封边7具有凸起部；所述凹陷部用于与相邻的围护墙体的聚氨酯泡沫封边7的凸起部配合连接，所述凸起部用于与相邻的围护墙体的聚氨酯泡沫封边7的凹陷部配合连接；通过凸起部和凹陷部使围护墙体形成模块化结构，多个围护墙体中相邻的围护墙体通过凸起部和凹陷部可以相互连接而形成面积较大的墙体。
内面板2上可以开设有用于吸声的开孔，内面板2上的开孔与第四芯层6上的穿孔位置对应，以便声音通过开孔和穿孔而被第二芯层4吸收。
外面板1与内面板2可以均为金属板，金属板可以选用铝镁锰板。外面板1与内面板2的厚度均为0.8mm。内面板2上开孔的孔径可以为5mm-8mm、孔间距可以为15mm-20mm、穿孔率可以为7％-10％。开孔的内面板2面对室内的噪声设备，铝镁锰板具有很好的耐腐蚀性和耐高温性，使用寿命长，另外铝镁锰板作为饰面具有简洁美观的特点。
围护墙体还可以包括端板。端板设置为两个，两个端板分别设置于多层 复合夹芯层与聚氨酯泡沫封边7的另外两侧，两个所述端板覆盖所述第一芯层3的端面、第二芯层4的端面和第四芯层6的端面，且两个所述端板均与外面板1、内面板2和两个聚氨酯泡沫封边7连接；以便通过两个端板、外面板1和内面板2将多层复合夹芯层和聚氨酯泡沫封边7包裹起来。端板与外面板1、内面板2和聚氨酯泡沫封边7的连接方式不做具体限制，能够实现连接功能即可，作为一示例，选用隐形钉连接。作为又一示例，两个端板中的一个端板和外面板1可以为同一基板的不同部分，两个端板中的另一个端板和内面板2可以为同一基板的不同部分；基板的材料不作限定，例如，基板可以为钢板。
外面板1、第一芯层3、第二芯层4、第三芯层5、第四芯层6和内面板2之间可以通过胶合剂粘接。多层复合夹芯层两侧采用聚氨酯泡沫封边7封边，并采用插接式隐形钉连接方式包边，另两侧用端板包边，生产工艺简单，安全可靠，成本低廉，并且可以实现装配式墙板快捷方便的安装，具有显著的直接效益和间接效益。
本发明的外面板1采用不开孔的铝镁锰板，内面板2采用开孔的铝镁锰板，内面板2与外面板1之间采用纤维水泥板加岩棉板的组合形式，内面板2穿孔外面板1不穿孔且增加岩棉板厚度至180mm以上，显著提高围护墙体的保温性能。将内面板2的穿孔侧面对室内的噪声设备提高围护墙体对噪声的吸声性能，内面板2和外面板1增强墙体的整体刚度，纤维水泥板提高墙体的面密度，提高墙体对低频噪声的隔声性能。
本发明的整体结构具有足够的机械强度、稳定性、安全性外，提高其保温性能、吸声性能和隔声性能，显著提高户内变电站的节能保温性能，并能显著降低变电站内部的噪声设备辐射到厂界的噪声，生产工艺简单，安全可靠，成本低廉。
以上仅为本发明的实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均包含在申请待批的本发明的权利要求范围之内。
