Assembled prestress anchor head, anchor sealing structure and construction process
The invention discloses an assembled prestress anchor head, an anchor sealing structure and a construction process. The anchor head comprises an anchor rope seal head and a working base. The bottom ofthe working base is fixedly connected to a frame beam or is integrally formed with the frame beam, the anchor rope seal head is fixedly connected to the working base, the anchor head is internally provided with a cavity for placing an anchor rope and an anchorage device, a slurry supplementing hole is formed in the side surface of the anchor head and communicates to the cavity, a cover plate is arranged on the top of the anchor rope seal head, and the cover plate is detachably connected to the anchor rope seal head. The anchor sealing structure comprises the frame beam, the anchor rope, the anchorage device and the anchor head. The working base and the anchor rope seal head can be stably fixed to the frame beam, so that the transfer direction of tension of the anchor rope and the qualityof the anchor sealing structure are guaranteed. After the anchor rope is stretched, slurry can be supplemented to a gap between the anchor rope and the anchor head. The cover plate can prevent rainwater from entering the anchor head to affect the anchor rope and the anchorage device so as to prevent failure of an anchoring system due to corrosion of the anchor rope and the anchorage device, so that the problem of durability and maintainability of an anchor rope locking end is solved.
本发明公开了拼装式预应力锚头、封锚结构及施工工艺，锚头包括锚索封头和工作底座，工作底座的底部用于与框架梁固定连接或一体成型设置，锚索封头与工作底座固定连接，锚头内部设有空腔，空腔用于放置锚索和锚具，锚头的侧面设有补浆孔，补浆孔与空腔连通，锚索封头的顶部设有盖板，盖板与锚索封头可拆卸地连接，封锚结构包括框架梁、锚索、锚具和锚头。工作底座和锚索封头使锚头能稳定固定在框架梁上，保证锚索拉力的传递方向和封锚结构的质量，在锚索张拉之后可以通过补浆孔为锚索和锚头之间的空隙进行补浆，盖板可以防止雨水进入锚头对锚索和锚具造成影响，防止锚索和锚具锈蚀从而导致锚固系统失效，解决了锚索锁定端的耐久性和可维护性问题。
