Large-diameter GFRP (glass fiber reinforced plastic) bar and steel bar combined anchor rod
The invention relates to the technical field of engineering, in particular to a large-diameter GFRP rib and steel bar combined anchor rod which comprises deformed steel bars, GFRP ribs, U-shaped buckles, a centering support and auxiliary fasteners, the multiple deformed steel bars are arranged around the side wall of the centering support at equal intervals, the two side walls of each deformed steel bar are welded to the side wall of the centering support, and the U-shaped buckles are arranged on the side wall of the centering support. The side wall of the bottom end of the deformed steel bar is buckled with the side wall of the top end of the GFRP bar through a plurality of U-shaped buckles, the GFRP bar is sleeved with a plurality of auxiliary buckles from top to bottom, and the GFRP bar is adopted at the bottom end of the anchor rod body, so that the weight of the structure is reduced; by means of the high tensile strength of the GFRP ribs, the large-diameter GFRP rib and deformed steel bar combined anchor rod can effectively resist buoyancy of underground water, it is ensured that an underground structure bottom plate cannot crack due to too large buoyancy, and the stability of an underground structure is improved; the GFRP ribs have excellent corrosion resistance and can resist corrosion of chemical substances in the underground environment, the service life of the anchor rod is prolonged, and the maintenance and replacement cost is reduced.
本发明涉及工程技术领域，特别涉及一种大直径GFRP筋与钢筋的组合式锚杆，包括：螺纹钢、GFRP筋、U型扣、对中支架和辅助扣件，多根所述螺纹钢等距环绕对中支架侧壁设置，每根螺纹钢两侧壁分别与对中支架侧壁焊接，螺纹钢底端侧壁通过多个U型扣与GFRP筋顶端侧壁扣接，GFRP筋由上至下上套装有多个辅助扣件，锚杆主体底端采用GFRP筋减轻了结构的重量；借助于GFRP筋的高抗拉强度，大直径GFRP筋与螺纹钢的组合式锚杆能够有效抵抗地下水的浮力，确保地下结构底板不会因浮力过大而开裂，并增加了地下结构的稳定性；GFRP筋具有优异的耐腐蚀性能，能够抵御地下环境中的化学物质侵蚀，延长锚杆的使用寿命，减少维护和更换成本。
