Embodiment Construction

[0011] Refer to the following figure 1 and figure 2 Specifically, an embodiment of an uplift anchor according to the present invention includes a columnar anchor body 1 , and at least one locator 2 is arranged vertically on the anchor body. The locator includes three locating protruding rings uniformly arranged around the outer circumference of the anchor rod body. The positioning convex ring is welded on the anchor rod body. The positioning convex ring forms an isosceles trapezoidal structure with the anchor body as the base.

[0012] Of course, as a modification of the above embodiment, the locator can also be designed as a rib structure, and the locating protruding ring can also adopt a triangular or semicircular structure.

Abstract

The invention discloses an anti-pull anchor rod. The anti-pull anchor rod comprises a columnar anchor rod body, wherein the anchor rod body is vertically provided with at least one positioner; the positioner comprises three positioning convex rings which are uniformly arranged on the outer circumference of the anchor rod body; and the positioning convex rings form an isosceles trapezoid structure by taking the anchor body as a bottom side. The anchor rod body is vertically provided with at least one positioner, so that the anti-pull strength is improved and the problems about the upward pull force of a pipe truss on a buttress and the floating force of underwater are solved.

Description

technical field [0001] The present invention relates to bolts. Background technique [0002] The grid support pier is a large-volume concrete box structure, and the complex force of the grid structure is transmitted to the support pier. In order to ensure the stability of the force of the support pier, the support pier adopts a reinforced concrete box structure to enhance the integrity, and the anchor rod is used to solve the problem of the pipe truss. The upward pull force on the buttress and the buoyancy of groundwater, as well as enhanced shear resistance. However, the pullout resistance of general anchor rods is weak. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pullout anchor rod, improve the pullout strength, and solve the problems of the upward pullout force of the pipe truss on the pier and the buoyancy of groundwater. [0004] In order to solve the above-mentioned technical problems, the present i...
