Description

Anti-floating anchor rod standard height control tool

Technical Field

The utility model relates to the technical field of anti-floating anchor rod height marking, in particular to an anti-floating anchor rod height marking control tool.

Background

In the prior art, a transverse short steel bar (limit steel bar) is welded at the orifice of the anti-floating anchor rod, and bricks, stones and other heavy objects are used for pressing the short steel bar so as to achieve the purpose of fixing the anti-floating anchor rod.

The prior method needs to weld a spacing reinforcing steel bar before grouting, needs to be cut off after grouting, increases the consumption and the manual expenditure of the reinforcing steel bar, is unfavorable for the acceleration of construction progress, and has larger elevation precision influenced by the elevation of the orifice position of the anchor rod.

The main construction procedures of the anti-floating anchor rod are as follows: anchor rod numbering and positioning, anchor rod manufacturing, pore forming, anchor rod placing and grouting. The placement of the anchor rod is prone to the following problems: (1) the anchor rod cannot be fixed; (2) the anchor rod is easy to be disturbed in the grouting process. The deviation between the standard height of the formed anti-floating anchor rod and the designed elevation is large, the height of the anti-floating anchor rod is uneven, and the problems that the anchor rod steel bar collides with the waterproof plate steel bar, the anchor rod steel bar is higher than the waterproof plate surface and the like are caused. Once grouting is finished on the anti-floating anchor rod, the elevation of the anchor rod is difficult to readjust, and only the cutting or welding mode can be adopted for adjustment, so that manpower and material resources are wasted greatly, and the construction period is greatly influenced.
