PSB finish-rolled deformed steel bar anti-floating anchor rod structure and construction method thereof
The invention provides a PSB finish-rolled deformed steel bar anti-floating anchor rod structure and a construction method thereof. The PSB finish-rolled deformed steel bar anti-floating anchor rod structure comprises a PSB finish-rolled deformed steel bar anchor rod body, a first anchor plate, a first anchor head, a second anchor plate and a second anchor head. After an anchoring body reaches thestrength required by tensioning, the PSB finish-rolled deformed steel bar anchor rod body can be tensioned and fixed through the first anchor plate and the first anchor head, the generated prestresscan enable the anchoring body to be in a pressed state, so that the anchoring body of the anchor rod is effectively controlled from generating cracks, the durability of the anti-floating anchor rod isimproved, and the anti-floating effect is consolidated. According to the construction method of the PSB finish-rolled deformed steel bar anti-floating anchor rod structure, prestress can be generatedonly by tensioning the anchor rod and additionally arranging the first anchor plate and the first anchor head to achieve the anti-cracking effect, and the construction method is simple and easy to operate.
本发明提供一种PSB精轧螺纹钢抗浮锚杆结构及其施工方法。本发明提供的PSB精轧螺纹钢抗浮锚杆结构，包括PSB精轧螺纹钢锚杆杆体、第一锚板和第一锚头、第二锚板和第二锚头，当锚固体达到张拉要求强度后可张拉PSB精轧螺纹钢锚杆杆体并通过第一锚板和第一锚头固定，由此产生的预应力能够使锚固体属于受压状态，从而有效控制锚杆锚固体产生裂缝，提高抗浮锚杆的耐久性，巩固抗浮效果。本发明提供的PSB精轧螺纹钢抗浮锚杆结构的施工方法，仅仅通过张拉锚杆和增设第一锚板、第一锚头固定就能产生预应力实现抗裂缝的效果，施工方法简单易操作。
