Waterproof prefabricated anchor block for prestressed anti-floating anchor rod and construction method
The invention discloses a waterproof prefabricated anchor block for a prestressed anti-floating anchor rod and a construction method, and relates to the technical field of building construction. The prefabricated concrete block is composed of a prefabricated concrete block, a prefabricated concrete block bottom reinforcing mesh, an anchor backing plate, an anchorage device and a spiral bar. Anchor holes are reserved in the axes of the prefabricated concrete blocks, and the centers of the anchor holes are aligned with the anchor bearing plates and the spiral bars. The prestressed tendons penetrate through the anchor holes to be tensioned and anchored on the top faces of the anchor blocks. And then a concrete cushion layer is poured, a waterproof layer is laid, finally, a concrete bottom plate is poured, and the prestressed tendons which are tensioned and anchored are anchored into the concrete bottom plate. The method is used for solving the problems that a basement bottom plate and a waterproof layer are penetrated by holes reserved by tensioning a pre-stressed anchor rod to cause waterproof failure, and the structure that an anchorage device protrudes out of the basement bottom plate is difficult to process.
本发明公开了一种用于预应力抗浮锚杆的防水预制锚块及施工方法，涉及建筑施工技术领域。它由预制混凝土块、预制混凝土块底部钢筋网、锚垫板、锚具、螺旋筋组成。预制混凝土块轴心处留有锚孔，锚孔中心与锚垫板及螺旋筋对齐。预应力筋穿过锚孔张拉并锚固在锚块顶面。再浇筑混凝土垫层，铺防水层，最后浇筑混凝土底板，将张拉锚固完毕后的预应力筋锚入混凝土底板中。本发明性新型用于解决地下室底板及防水层被预应力锚杆张拉预留的孔洞穿透导致防水失效，以及锚具凸出地下室底板结构处理困难的问题。
