Description

Technical Field

[0001] The utility model relates to the technical field of reinforced structures, in particular to an anchor bar for reinforcing an earth-rock dam. Background Art

[0002] Anchor bars are mainly used to actively reinforce slopes, tunnels, and dam bodies. As tensile components deep into the ground, one end is connected to the engineering structure, and the other end is deep into the ground. Their function is to increase the bonding friction between the anchor body and the soil layer, increase the bearing capacity of the anchor body, and transmit the tension of the free section to the deep soil.

[0003] Existing anchor bars are generally single straight steel bars. Although the structure is simple, they have defects such as low tensile strength, poor adhesion with concrete, and low friction, which affect the strength of their anchoring. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and provides an anchor bar for reinforcing an earth-rock dam.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] An anchor bar for reinforcing an earth-rock dam comprises three single bars, one end of each of which is fixedly connected to an end plate, a plurality of winding stirrup segments are arranged outside the three single bars, and a plurality of reinforcing anchor columns are welded to the outer circumference of the three single bars.

[0007] Three single ribs pass through the end plate and are provided with bending sections, and the three bending sections are evenly distributed on the circumference.

[0008] A plurality of anchoring protrusions are provided on the side wall of the end plate.

[0009] The three single ribs are provided with bending sections.

[0010] The beneficial effects of the utility model are as follows: the utility model is composed of three single reinforcement bars, and at the same time, the end plate, the wrapped stirrup section and the reinforced anchor column can improve the bonding and friction with the concrete, thereby improving the anchoring strength.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figure 1 As shown, an anchor bar for reinforcing an earth-rock dam comprises three single bars 1, one end of each of the three single bars 1 is fixedly connected to an end plate 2, a plurality of wrapped stirrup segments 3 are arranged outside the three single bars 1, and a plurality of reinforcing anchor columns 4 are welded to the outer circumference of the three single bars 1.

[0019] Three single ribs 1 pass through the end plate 2 and are provided with bent sections 5 . The three bent sections 5 are evenly distributed around the circumference.

[0020] A plurality of anchoring protrusions 6 are provided on the side wall of the end plate 2 .

[0021] The three single ribs 1 are provided with bending sections 7 .

[0022] The three individual ribs 1 can be wound together or welded together, which can improve the anchoring strength.

[0023] The utility model is composed of three single reinforcement bars 1. At the same time, the end plate 2, the wrapped stirrup section 3, the reinforced anchor column 4, the bent section 5, the anchor protrusion 6 and the bent section 7 can improve the bonding and friction with the concrete, thereby improving the anchoring strength.
