The invention provides a gum-injectable anti-seepage expansion screw, which comprises a screw. One end of the screw is provided with an inverted conical expansion head, the screw is provided with an external thread relative to one end of the expansion head, the screw is covered with an expansion tube, the expansion tube is directed towards the outer wall of one end of the expansion head, and the screw center is provided with a number of expansion grooves. The expansion head end is provided with a shunt groove connected with the flow channel, the shunt groove is uniformly arranged with the center axis of the flow channel; the outer wall of the expansion head is provided with a backflow groove connected with the shunt groove; the outer thread is provided with a nut and a sealing gasket, and the sealing gasket is arranged on the outer thread. Located between nut and expansion tube. By setting a runner on the screw, the waterproof property of the wall can be effectively prevented after the expansion screw is installed, and the anti-corrosion effect of the expansion head and the expansion pipe of the expansion screw can be provided by the injection.

一种可注胶防渗漏膨胀螺钉
本专利技术涉及建筑领域，具体涉及一种可注胶防渗漏膨胀螺钉。
技术介绍
膨胀螺钉在建筑领域非常常见，往往用来安装各种吊顶、路灯等物件，但是现有的膨胀螺钉在安装时会在墙体上进行开设安装孔，因此在户外会导致雨水进入安装孔腐蚀螺钉或墙体内的钢筋，尤其是膨胀螺钉在安装膨胀后，有可能会导致安装孔内壁产生裂纹，这会使雨水随着裂纹渗入墙体深处，对墙体的破坏逐步扩大。
技术实现思路
基于上述问题，本专利技术目的在于提供一种可在安装后对安装孔内进行注胶防水的可注胶防渗漏膨胀螺钉。针对以上问题，提供了如下技术方案：一种可注胶防渗漏膨胀螺钉，包括螺钉，所述螺钉一端设有倒锥形膨胀头，所述螺钉相对于膨胀头的一端设有外螺纹，所述螺钉外部套有膨胀管，所述膨胀管朝向膨胀头一端的外壁设有若干膨胀槽，所述螺钉中心设有沿其轴向方向对通开设的流道。上述结构中，通过在螺钉中间设置流道，在螺钉安装完成后通过流道向墙体上的安装孔内填充防水胶(可以为玻璃胶、防水沥青等)，避免雨水进入安装孔。本专利技术进一步设置为，所述膨胀头端部设有与流道相连通的分流槽，所述分流槽以流道中心轴线为圆心均布设置...
