Abstract

The utility model relates to an upside-down anchor rod head, which includes an upside-down piece, a spiral ring and a spiral tube. Among them, there are six upside-down pieces. The upside-down piece is connected with the spiral ring and the bottom end of the spiral tube by welding, the spiral ring is sleeved on the spiral tube and connected by threads, and the spiral tube is also fixed on the anchor rod body by threads. Due to the upside-down effect formed by the upside-down piece and the borehole wall, the utility model improves the anchoring strength of the anchor rod, is simple to operate, can be recycled, and is convenient for installation.

Description

An upside-down anchor rod head

technical field

The utility model relates to an upside-down anchor rod head, which is mainly used in the technical field of geotechnical engineering.

Background technique

In the existing technical field of geotechnical engineering, bolts are widely used as an effective support tool. The traditional anchor head has the following defects:

1. The anchoring strength is small;

2. One-time use;

 3. The anchoring effect is not good.

Contents of the invention

The utility model provides an upside-down anchor head, which can make up for the above shortcomings, better meet the support strength requirements, achieve better support effects, and can be recycled at the same time.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

An upside-down anchor rod head, including an upside-down piece, a spiral ring, and a spiral tube, wherein the upside-down piece, the spiral ring, and the bottom end of the spiral tube are welded, the spiral ring is sleeved on the spiral tube, and connected by threads, and the spiral tube is also threaded fixed on the anchor body.

As a preferred solution of the utility model, the upside-down piece of the upside-down anchor head is evenly welded on the spiral ring, so that the upside-down piece and the borehole wall are evenly stressed.

As another preferred solution of the present utility model, the spiral ring of the upside-down anchor rod head just fits on the spiral tube and is threadedly connected, and the spiral tube is also fixed on the anchor rod body through threaded connection.

The beneficial effect of the utility model is: when installing, the anchor rod can be directly screwed into the anchor rod head, inserted into the drilled hole, and then the tray is installed and the nut is tightened. The upside-down piece and the borehole wall form an upside-down effect, which improves the anchoring strength of the anchor rod. The screw tube, the anchor rod body, and the spiral ring are all connected by threads, which is easy to operate, easy to install, and can be recycled.

Description of drawings:

In order to illustrate the technical solution of the utility model more clearly, the accompanying drawings required for the technical solution will be briefly introduced below.

Reference signs: 1-upside-down piece; 2-spiral ring; 3-coil; 4-external thread; 5-bolt body.

Detailed ways:

The utility model will be further described in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the utility model is an upside-down anchor rod head, which includes an upside-down piece (1), a spiral ring (2), a spiral tube (3), and an external thread (4). As shown in Figure 2, there are six upside-down pieces (1).

The upside-down piece (1) is pre-welded on the bottom of the spiral tube (3), and the spiral ring (2) is set on the screw

On the pipe (3), it is connected and fixed through the external thread (4). Then the upside-down piece (1) and the spiral ring (2) are welded, and after the welding is completed, they are fixed on the anchor rod body (5) as a whole through screw connection.

Claims (3)

1. An upside-down anchor rod head, characterized in that: the anchor rod head includes an upside-down piece, a spiral ring, and a spiral tube, wherein there are six upside-down pieces, and the upside-down piece, the spiral ring, and the bottom end of the spiral tube are welded. 2. An upside-down bolt head according to claim 1, characterized in that: the upside-down piece is evenly welded on the spiral ring, so that the upside-down piece and the borehole wall are evenly stressed. 3. An upside-down anchor head according to claim 1, characterized in that: the spiral ring just fits on the spiral tube and is threaded, and the spiral is also fixed on the anchor body through threaded connection.
