Prestress anti-floating anchor rod for pre-tensioning method construction
The invention discloses a pre-stress anti-floating anchor rod for pre-tensioning method construction. The pre-stress anti-floating anchor rod comprises a rod body and a top anchor bearing plate arranged at the top end of the rod body. The rod body is connected with a bottom cushion layer in a pouring mode, the position, corresponding to the top anchor bearing plate, of the rod body is connected with a formed bottom plate through pouring, and the rod body comprises an outer rod used for being connected with the bottom cushion layer in a pouring mode and a rod core penetrating through the inner portion of the outer rod. The top anchor bearing plate is connected with the rod core, and a counter-force support is arranged between the top anchor bearing plate and the top end of the outer rod. The top anchor bearing plate provides prestress for the outer rod through the counter-force support. A plurality of radial supporting ribs are welded to the top anchor bearing plate in the circumferential direction of the top anchor bearing plate, one end of each supporting rib is connected with the top anchor bearing plate, and the other end of each supporting rib abuts against the bottom cushion layer to provide prestress for the bottom plate. The working hours can be shortened, the procedure of filling gaps through grouting can be avoided through the pre-tensioning method, and the possibility of water leakage is reduced.
本发明公开了一种用于先张法施工的预应力抗浮锚杆，包括杆体、设置在杆体顶端端部的顶部锚垫板；所述杆体与底部垫层浇注连接，且该杆体对应顶部锚垫板的位置通过浇注与形成的底板连接，所述杆体包括用于与底部垫层浇注连接的外杆、贯穿在外杆内部的杆芯；所述顶部锚垫板与杆芯连接，且顶部锚垫板与外杆的顶部端部之间设置有反力支架；所述顶部锚垫板通过反力支架向外杆提供预应力；所述顶部锚垫板沿其周向焊接有若干放射状的支撑筋，该支撑筋的一端与顶部锚垫板连接，另一端与底部垫层抵接，以提供底板预应力。本发明能够缩短工时，并且采用先张法能够避免灌浆填充空隙的工序，降低漏水的可能性。
