Problems solved by technology

[0008] One of the purposes of the present invention is to propose a composite anchor structure of GFRP bars and steel strands and its use method, which solves the problem of waste of materials in the prior art when steel strands are used as anchors, and damage to personnel during the removal process. Potential hazards and the technical problems that GFRP tendons are easy to break from the root of the anchor when using GFRP tendons as anchor rods, and the use of anchors to clamp GFRP tendons requires a high level of construction technology

Embodiment 1

[0033] This embodiment describes in detail the composite anchor rod structure of GFRP bars and steel strands of the present invention.

[0034] The GFRP tendon and steel strand composite anchor structure 10 of the present embodiment includes an anchorage section 101, a rod body section 102 and an anchor section 103, such as figure 2 shown. Preferably, the anchorage segment 101 is fixed in the anchorage 30, and the anchorage segment 101 is a steel strand; the rod body segment 102 is connected to the anchorage segment 101, and the rod body segment 102 is composed of GFRP bars and steel strands; anchoring The section 103 is connected with the rod body section 102, and the anchor section 103 is compounded by GFRP bars and cement paste. Specifically, the anchorage section 101 is fixed in the anchorage 30, and a load is applied to the anchorage 30 through a jack, and the anchorage 30 transmits the load to the anchorage section 101, as figure 1As shown; the anchorage section 101 t...

Embodiment 2

[0048] This embodiment describes in detail the usage method of the GFRP tendon and steel strand composite anchor structure of the present invention.

[0049] In the method of using the GFRP bar and the steel strand composite anchor structure 10 of any one of the technical solutions in Embodiment 1, the GFRP bar and the steel strand of the rod body section 102 are connected in the following manner: a clip is installed in the sleeve 202, The steel strand is inserted into the sleeve 202 and the steel strand is clamped and fixed by clips; the nut 201 is screwed into the sleeve 202 , and the GFRP tendon is screwed into the nut 201 .

[0050] Concretely, the connection of the GFRP tendon of the rod body section 102 and the steel strand includes the following steps:

[0051] S1: Select the steel strand as the rod body, the nominal diameter of the steel strand is 21.8mm, and the cut length is 5m;

[0052] S2: The clip is installed in the sleeve 202, the clip is 3 pieces, and the clip...

Abstract

The invention discloses a GFRP rib and steel strand combined type anchor rod structure and a using method thereof, and relates to the field of constructional engineering. The GFRP rib and steel strand combined type anchor rod structure comprises an anchorage device section, a rod body section and an anchoring section, the anchorage device section is fixed in an anchorage device, and the anchorage device section is a steel strand; the rod body section is connected with the anchorage device section, and the rod body section is formed by compounding GFRP ribs and steel strands; the anchoring section is connected with the rod body section, and the anchoring section is formed by compounding GFRP ribs and cement paste. According to the GFRP rib and steel strand combined type anchor rod structure, the steel strand is used in the anchorage device section connected with the anchorage device, the steel strand is not prone to breakage, special construction equipment is not needed when the steel strand is connected with the anchorage device, the construction process is simple, the speed is high, and the construction quality reliability is high; the rod body section is formed by compositing the GFRP ribs and the steel strands, so that material waste caused by excessive use of the steel strands can be avoided; the anchoring section is the GFRP rib, and after the GFRP rib intrudes into the red line, the GFRP rib is easy to cut, and potential danger cannot be caused to cutting personnel.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a composite anchor structure of GFRP bars and steel strands and a method for using the same. Background technique [0002] The prestressed anchor cable support system of foundation pit engineering is a temporary structure, which loses its function after the foundation pit support is completed. The rod body in the anchor cable part is a steel strand, and the steel strand is mostly used in permanent support structures. It is used as a temporary structure for a short time, resulting in a great waste of materials; the length of the prestressed steel strand anchor cable can reach several Ten meters, often intruding outside the red line, adjacent engineering construction needs to cut steel strands, and the steel strands break during the cutting process, which will cause potential danger to the cutting personnel. [0003] In recent years, some experts and scholars have...
