Abstract
The utility model discloses an anchor rod centering machine which comprises a circular ring body formed by connecting two semicircular rings, wherein one ends of the two semicircular rings are rotatably connected, and the other ends of the two semicircular rings are movably buckled; an inner side wall formed by the two semicircular rings is provided with continuous internal screw threads and external screw threads corresponding to the internal screw threads of the inner side wall of the centering machine are arranged at both ends of an anchor rod unit pipe. The centering machine is matched with an anchor rod for use during the installation process of the anchor rod, so as to ensure that the body of the anchor rod is positioned at the center of a pore diameter, prevent the anchor rod from deviating from a central line, achieve centering effect and ensure grouting effect; during the process that the anchor rod is installed upwards, the anchor rod can be assisted to be fixed temporarily, and the anchor rod centering machine is beneficial to successfully finishing grouting installation work of the anchor rod.
Description
Technical field
The utility model belongs to geotechnical engineering anchoring field, is specifically related to the anchor pole centralizer.
Background technology
In underground construction, mine working, railway tunnel, Hydraulic and Hydro-Power Engineering and side slope protection engineering construction process, for prevent stratum deformation, cave in, unstability and need the stratum being reinforced, the major measure that adopts is to bury anchor pole in the stratum underground, utilize the pulling force of anchor pole and with the integrated concrete grouting body of anchor pole with stratum consolidation, so that the stratum forms the globality structure, thereby reach the purpose of its distortion of control.Anchor pole is connected to form by linkage by some anchor pole unit pipes usually, but existing anchor pole unit pipes linkage structure is complicated, and more loaded down with trivial details during installation, parts are many, the cost of manufacture height.
The utility model content
The utility model provides a kind of anchor pole unit pipes of being convenient to connect at the deficiency that above-mentioned prior art exists, and plays the centering effect, can guarantee that the anchor pole unit pipes is positioned at aperture center, avoids anchor pole to depart from center line, guarantees the anchor pole centralizer of slip casting effect.
The utility model is achieved through the following technical solutions: the anchor pole centralizer, it is characterized in that: comprise the torus that is formed by connecting by two semicircular ring, two semicircular ring one ends are rotationally connected, the active buckle of two semicircular ring other ends, the inside wall of two semicircular ring formation is provided with continuous internal thread, and anchor pole unit pipes two ends are provided with the external screw thread corresponding with the internal thread of centralizer inside wall.Centralizer cooperates anchor pole to use, and is used for the anchor pole installation process, guarantees that anchor bar body is positioned at aperture center, avoid anchor pole to depart from center line, play the centering effect, guarantee slip casting effect, anchor pole makes progress in the installation process, can assist anchor pole temporary fixed, helps finishing smoothly of anchor pole grouting installation work.
Also evenly be laid with some hemispherical projections on the described torus outer ring surface.Can reduce the centralizer working resistance.
Improved, the outer eaves of described torus upper and lower end face is provided with chamfering.
Described centralizer surface has three layers of anticorrosive coat at least, and wherein bottom is the galvanizing by dipping layer, and the middle level is that zinc-manganese is phosphate coat, and surface layer is the powder thermosetting coating.
The utility model anchor pole centralizer cooperates anchor pole to use, be used for the anchor pole installation process, guarantee that anchor bar body is positioned at aperture center, avoid anchor pole to depart from center line, play the centering effect, guarantee slip casting effect, anchor pole makes progress in the installation process, can assist anchor pole temporary fixed, help finishing smoothly of anchor pole grouting installation work.The utility model is simple in structure, and is easy to process, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model anchor pole centralizer;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the utility model anchor pole centralizer, be used for the connection of anchor pole unit pipes, it comprises the torus that is formed by connecting by two semicircular ring 1, two semicircular ring one ends are rotationally connected, the active buckle of two semicircular ring other ends, the inside wall of two semicircular ring formation is provided with continuous internal thread, and anchor pole unit pipes two ends are provided with the external screw thread corresponding with the internal thread of centralizer inside wall.Also evenly be laid with some hemispherical projections 2 on described two semicircular ring outer ring surfaces, the outer eaves of torus upper and lower end face is provided with chamfering 5.As shown in the figure, two semicircular ring active buckles are realized that by the clasp 3 that is located at two semicircular ring ends respectively and buckle 4 two semicircular ring are rotationally connected then can connect by pin and realize.Described centralizer surface has three layers of anticorrosive coat at least, and wherein bottom is the galvanizing by dipping layer, and the middle level is that zinc-manganese is phosphate coat, and surface layer is the powder thermosetting coating.
