Abstract

楼层间水管密封装置,由L型水膨胀橡胶密封环,和紧箍在水膨胀橡胶密封环外圆周的双连塑料环连在一起组成。本实用新型安置在下水管外管壁与楼板防水层之间,楼层间水管密封装置的L型水膨胀橡胶环互相垂直的两个矩形环分别与楼层间水管外管壁和楼板防水层组成二对密封副,L型水膨胀橡胶密封环遇到水时体积会膨胀,由于L形水膨胀橡胶密封环的外圆周紧箍有双连塑料环,水膨胀橡胶遇到水时体积膨胀产生的过盈力可使密封更为可靠。

Description

楼层间水管密封装置
本实用新型涉及一种楼层间水管或水管套管的密封件。
楼层间水管从建筑楼房的楼板中穿过,通到下一层房间,有时水管外套有套管,在安装过程中,外管壁与楼板之间不可避免地产生环形间隙。已有技术中,外管壁与楼板之间没有严格的密封,地面上的积水可以沿水管或套管的外管壁,从水管或套管的外管壁与楼板之间的环形间隙流到下一层房间。
本实用新型的目的是为了克服上述不足,提出一种可以防止地面积水从水管或套管的外管壁与楼板之间的环形间隙流到下一层房间的楼层间水管密封装置。
本实用新型是用如下方法实现的。
本实用新型的发明方案是在穿过楼板的楼层间水管或套管的外管壁与楼板上的防水层之间安置有密封装置,当地面积水沿外管壁流下时,该装置可阻止水从楼层间水管或套管的外管壁与楼板之间的环形间隙流到下一层房间。
为实现上述发明方案,楼层间水管密封装置有L型水膨胀橡胶密封环,L型水膨胀橡胶密封环有互相垂直的两个矩形环,在L型水膨胀橡胶密封环外圆周紧箍有双连塑料环,双连塑料环有不等径的上、下两个同心的塑料环,两个塑料环之间、沿塑料环的圆周均布有四个连接筋,两个塑料环中,上部塑料环的截面是直角梯型,下部塑料环的截面是矩形,双连塑料环可紧箍在L型水膨胀橡胶密封环外,保持L型水膨胀橡胶密封环的位置和形状,安装后,L型水膨胀橡胶密封环互相垂直的两个矩形环分别与楼层间水管或套管外管壁和楼板防水层组成互相垂直的二对密封付。
安装时,本实用新型套在穿过楼板的水管或套管上,安置在水管或套管外管壁与楼板上防水层之间,楼层间水管密封装置的L型水膨胀橡胶密封环互相垂直的两个矩形环分别与楼层间水管或套管的外管壁和楼板上防水层组成二对密封付,在L型水膨胀橡胶密封环的外圆周紧箍有双连塑料环,可使楼层间水管或套管的外管壁与楼板之间的环形间隙得到密封,特别是当L型水膨胀橡胶密封环遇到水时体积会膨胀,由于L形水膨胀橡胶密封环的外圆周紧箍有双连塑料环,L形水膨胀橡胶密封环遇到水时体积膨胀产生的过盈力可使密封更为可靠。
下面结合附图,对本实用新型作进一步的说明。
图1是楼层间水管密封装置的立体局剖示意图;
图2是安装后的楼层间水管密封装置示意图。
图1、图2中,楼层间水管密封装置有L型水膨胀橡胶密封环1,L型水膨胀橡胶密封环1有互相垂直的两个矩形环11、12,在L型水膨胀橡胶密封环1外圆周紧箍有双连塑料环2,双连塑料环2有不等径的上、下两个同心的塑料环21、22,两个塑料环21、22之间、沿塑料环的圆周均布有四个连接筋23,两个塑料环中,上部的塑料环21的截面是直角梯型,下部的塑料环22的截面是矩形,双连塑料环2可紧箍在L型水膨胀橡胶密封环1外,塑料环21紧箍在矩形环11的外圆周,塑料环22紧箍在矩形环12的外圆周,双连塑料环2可保持L型水膨胀膨胀橡胶密封环1的位置和形状,安装后,L型水膨胀橡胶密封环1互相垂直的两个矩形环分别与楼层间水管或套管3外管壁和楼板防水层4组成互相垂直的二对密封付,双连塑料环2可紧箍在L型水膨胀橡胶密封环1外。
