Embodiment

[0016] The embodiment of the present invention provides a square bolt and anchor cable, see Figure 1 to Figure 4 , the cross-section of the square anchor and anchor cable is a square, and the square anchor and anchor cable includes an anchor fixing section 1, an anchor rod body 2 arranged in the anchor fixing section 1, and a rod body arranged on the anchor rod body 2 Bracket 3.

[0017] Specifically, the anchor rod body 2 is made of steel bars or steel strands. One end exposed after the anchor rod body 2 is arranged in the anchor rod fixing section 1 is the anchor rod free section 21 .

[0018] In detail, a square with perimeter a has side length B=a / 4 and its area is u p1 =a 2 / 16; the diameter of a circle whose circumference is a is D=a / 3.14, and its area is u p2 = a 2 / 12.56; u p1 / u p2 =( a 2 / 16) / (a 2 / 12.56)= 0.785=78.5%; B / D=(a / 4) / (a / 3.14)=0.785=78.5%; that is, the area of ​​a square with the same perimeter is 0.785 of that of a circle. Rod (cable) Technical...

Abstract

The invention discloses a square anchor rod anchor cable and belongs to the building field. A cross section of the square anchor rod anchor cable is square, the square anchor rod anchor cable comprises an anchor rod fixed section, an anchor rod body arranged in the anchor rod fixed section and a rod body support arranged on the anchor rod body. Compared with round anchor rod anchor cables and under the same-length and same-sectional-area conditions, axial tension bearing capacity of the square anchor rod anchor cable is improved, the anchor rod anchor cable number is decreased. Under the same axial tension bearing capacity situation, the length of the anchor rod anchor cable is decreased, the sectional area of the anchor rod anchor cable is decreased, and the construction cost of a single anchor rod is reduced.

Description

technical field [0001] The invention relates to the construction field, in particular to a square anchor rod and anchor cable. Background technique [0002] The holes of various types of anchors (cables) used in various slope and pit support are all circular in shape, and the bearing capacity of the anchor is the friction value between the anchor and the surrounding soil. The cross-section of conventional anchors (cables) is circular, which is characterized by the smallest perimeter in geometric figures with equal areas, that is, circular anchors (cables) with the same cross-sectional area have a small contact area with the surrounding soil. It is not conducive to giving full play to the frictional resistance of the surrounding soil to the anchor. Contents of the invention [0003] In order to solve the problems in the prior art, an embodiment of the present invention provides a low-cost square bolt and anchor cable. Described technical scheme is as follows: [0004] An...
