Abstract

The invention relates to a split fabricated type centering bracket for an anchor rod and the anchor rod. The split fabricated type centering bracket for the anchor rod comprises T-shaped plugs, supporting frames and lock rings; and the T-shaped plugs are composed of lock heads composed of rib support bodies and tapered spring bolts and plug columns, annular lock seams are formed between the rib support bodies and the tapered spring bolts, and the lock rings sleeve the tapered spring bolts in a screwing confection mode. T-shaped clamping slots are formed in the plug columns circularly, the T-shaped clamping slots extend from one ends of the plug columns to the other ends of the plug columns, and the T-shaped clamping slots extend from the outer walls of the plug columns to the centers of the plug columns. The supporting frame comprises two semi-cylindrical supporting frames, T-shaped clamping rails are arranged on the inner walls of the supporting frames, the T-shaped clamping rails arematched with the T-shaped clamping slots in the plug columns, and guide plates are arranged at the axial ends of the supporting frames. The T-shaped plug, the supporting frames and the lock rings adopt split fabricated structures, the on-site construction efficiency is greatly improved, the installation is very convenient, and the split fabricated type centering bracket can be modularized and standardized and can be processed in batches.

Description

technical field [0001] The invention relates to a split-assembled centering support and an anchor rod for anchor rods. Background technique [0002] As an efficient and economical support technology, bolt support technology has been widely used in civil engineering, water conservancy, mining, transportation, urban infrastructure and geological disaster prevention and other engineering constructions, and plays an extremely important role. Taking the traditional tension anchor as an example, it consists of a free section and an anchor section, in which the anchor section relies on the bond between the anchor bar and the grout to transfer the load to the interface between the grout and the soil, thus ensuring the anchorage. The pull-out capacity of the rod. However, during the construction process, most of the existing anchor rods use a 6mm-diameter smooth round steel bar to weld the centering bracket (the steel bar body is mostly used) or a plastic chuck is used for centering...
