CN201908670U - Anchorage device with prestressed anchor rod - Google Patents

Abstract

The utility model provides an anchorage device with a prestressed anchor rod, which comprises a rob body and a tray with a conical hole in the center, wherein the rod body is connected to the tray through a clamping piece which is placed at the center of the tray, and is a spiral fin steel wire, the surface of the spiral fin steel wire is provided with four bulges which are spirally wound in parallel, the nominal diameter of the spiral fin steel wire is 10mm, the clamping piece is in a triple-piece type, and the tray has a round platform shape. The anchorage device with the prestressed anchor rod has the beneficial effects of simple structure, no reduction in the bearing capacity of the anchor rod and good anchoring effect.

Description

A kind of prestressed anchor ground tackle

Technical field

The utility model belongs to the compressor wire product scope, especially relates to a kind of prestressed anchor ground tackle.

Background technology

Anchor pole ground tackle in existing technology, be to body of rod end machining screw, the mode that screws with nut realizes the anchoring to the rock stratum again, following problem often appears when reality is used: 1, body of rod end machining screw, cause body of rod end cross-sectional area to reduce, the anchor pole supporting capacity descends, and thread root exists stress to concentrate when stressed, the phenomenon of anchor pole root fracture often occurs, have serious potential safety hazard; 2, the body of rod of existing anchor pole ground tackle mostly is the single-point convex, and convex shape is discontinuous, makes anchoring effect undesirable.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, do not reduce anchor pole supporting capacity, the good prestressed anchor ground tackle of anchoring effect.

The technical solution of the utility model is: a kind of prestressed anchor ground tackle, comprise that the body of rod and center have the pallet of bellmouth, the described body of rod is connected on the pallet by the intermediate plate that is positioned over described pallet center, the described body of rod is a helix rib steel wire, the surface of described helix rib steel wire have 4 parallel shapes in the shape of a spiral around projection, described helix rib steel wire nominal diameter is 10mm.

Described intermediate plate is a three-chip type.

Described pallet is round table-like.

Advantage and the good effect that the utlity model has are:

1, security reliability height, non-nut screws the mode anchoring, and the anchor pole prestressed improves greatly;

2, the anchor pole ground tackle body of rod is the standard workpiece, and stripping rib, the rolled thread processing of steel is carried out at the scene of need not, and has avoided the damage of the body of rod;

3, body of rod surface has the spiral ribs of continuous type, has increased the anchoring effect of anchor pole ground tackle greatly.
