Mechanical connection type anchor rod

Abstract

The invention discloses a reinforced bar anchor rod with a mechanical connection type reusable anchor rod body, which is used in the field of geotechnical engineering. The reinforced bar anchor rod is invented in order to realize the following three purposes: (1). after the anchor rod is not in use, the anchor rod body can be removed so as to be recycled, thereby the engineering cost is reduced; (2) the residues of reinforced bars do not exist outside a building restriction line so that the construction of adjacent unbuilt structures is not affected; and (3) resources are saved, and the energy conservation and emission reduction is facilitated. The reinforced bar anchor rod with the mechanical connection type reusable rod body comprises a reinforced bar anchor rod body, a pressure-bearing plate, a (connecting) nut, a supporting frame, an anti-bonding casing pipe, an anchor backing plate, a (locking) nut and the like. The principle of the reinforced bar anchor rod with the mechanical connection type reusable rod body is as follows: according to the positive and negative screw connecting mechanism of a thread, the anchor rod body is connected through a right-hand thread and is connected with a pressure-bearing disc arranged at the bottom of the anchor rod through a left-hand thread, and when the anchor rod is not in use, the anchor rod body is right-handed and rotated so that the anchor rod body is separated from the pressure-bearing plate; and a hollow lifting jack is used for pulling out the anchor rod body.

Description

technical field [0001] The invention relates to a mechanically connected rod body and a reusable steel anchor rod in the rock and soil anchoring field. The anchor rod is a tension rod body buried in the soil layer or rock layer, and the other end is connected with the engineering structure. Its basic function is to transfer the tension generated by the earth pressure, water pressure, wind load or unbalanced load of the structure itself to the soil or rock layer to maintain the safety and stability of the structure. Background technique [0002] There are three major types of anchor bodies for anchors currently used in the rock and soil anchoring field. One is steel bars, including ribbed steel bars and non-ribbed steel bars; the other is steel strands or scrap steel wire ropes; the third is organic materials, such as fiberglass wire or carbon fiber. After the above-mentioned materials are used as anchor rod bodies, they are difficult to recycle and can only be buried in th...

AI Technical Summary

Problems solved by technology

After the above materials are used as anchor rod bodies, it is difficult to recycle and can only be buried in the soil for a long time

Although steel strands are used as the anchor body (also known as the anchor cable body), although it can be recycled, the reusability is poor

This will cause obstacles outside the red line of the building, making it difficult to construct the building in the later stage; if there is a subway tunnel construction in the later stage, the bolt body will cause damage to the cutting equipment of the shield machine

In addition, a large amount of engineering materials are wasted
