Abstract
The utility model discloses a pulling-resistant anchor rod, which includes a columnar anchor rod body, wherein the anchor rod body is vertically provided with at least one positioner; each positioner includes three positioning convex rings uniformly arranged around the outer circumference of the anchor rod body; and the positioning convex rings taking the anchor rod body as the bottom edge form an isosceles trapezoid structure. As the at least one positioner is arranged in the vertical direction of the anchor rod, the pulling-resistant intensity is improved, the difficult problem of the resistance of a pipe truss frame to the upward pulling force of a buttress and buoyancy of groundwater is solved.
Description
Technical field
The utility model relates to anchor pole.
Background technology
The rack buttress is the concrete in mass case structure; The complicated applied force of rack passes to buttress, and in order to ensure the stability under loading of buttress, buttress adopts the box structure agents enhance overall property of steel concrete; Adopt anchor pole solve the pipe truss to buttress to uplift force and phreatic buoyancy, and strengthen shearing resistance.But general anchor pole resistance to plucking ability a little less than.
The utility model content
The utility model technical problem to be solved just provides a kind of uplift anchor, improves pulling test strength, solves the problem to uplift force and phreatic buoyancy of pipe truss to buttress.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of uplift anchor, comprise the bolt body of a column, and it is characterized in that: said bolt body vertically is provided with at least one locator.
As preferably, said locator comprises three positioning convex rings that ring bolt body excircle evenly is provided with.
As preferably, said positioning convex ring is that the base forms isosceles trapezoidal structure with the bolt body.
The utility model vertically is provided with at least one locator in bolt body; And locator structure innovation; Adopt the positioning convex ring structure of isosceles trapezoidal structure, thereby improved pulling test strength, solved the difficult problem to uplift force and phreatic buoyancy of pipe truss buttress.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is anchor pole partial structurtes sketch mapes;
Fig. 2 is an A-A cross-sectional view among Fig. 1.
The specific embodiment
Below seeing figures.1.and.2 specifies the embodiment of a kind of uplift anchor of the utility model, comprises the bolt body 1 of a column, and said bolt body vertically is provided with at least one locator 2.Said locator comprises three positioning convex rings that ring bolt body excircle evenly is provided with.Positioning convex ring is welded on the bolt body.Said positioning convex ring is that the base forms isosceles trapezoidal structure with the bolt body.
Certainly, as the distortion of the foregoing description, locator also can be designed to rib structure, and positioning convex ring also can adopt triangle or semicircular structure.
Claims (3)
1. uplift anchor comprises the bolt body (1) of a column, and it is characterized in that: said bolt body vertically is provided with at least one locator (2).
2. a kind of uplift anchor according to claim 1 is characterized in that: said locator comprises three positioning convex rings that ring bolt body excircle evenly is provided with.
3. a kind of uplift anchor according to claim 2 is characterized in that: said positioning convex ring is that the base forms isosceles trapezoidal structure with the bolt body.
