Fiber glass reinforced plastics anchor rod supporting structure and fiber glass reinforced plastics anchor rod

Abstract

The invention discloses a fiber glass reinforced plastics anchor rod supporting structure and a fiber glass reinforced plastics anchor rod. The fiber glass reinforced plastics anchor rod supporting structure comprises a supporting frame and a fiber glass reinforced plastics anchor rod body, the supporting frame comprises a supporting base plate, a plurality of first connecting arms are arranged on the outer side of the supporting base plate, inner connecting arms are arranged at the end portions of every two adjacent first connecting arms, a second connecting arm is arranged on each inner connecting arm, and outer connecting arms are arranged between every two adjacent second connecting arms. Every two inner connecting arms are connected with the corresponding first connecting arm through a connecting seat, every two outer connecting arms are connected with the corresponding second connecting arm through a connecting seat, and anchor rod holes are formed in the middle portions of the outer connecting arms, the middle positions of the connecting seats, and the middle positions of the supporting base plate correspondingly. The fiber glass reinforced plastics anchor rod body is fixed in the anchor rod holes, a drill bit is arranged at the front end of the fiber glass reinforced plastics anchor rod body, and a nut, a auxiliary supporting plate, a holding plate and a grouting stop piece are arranged at the rear end of the anchor rod body sequentially. The fiber glass reinforced plastics anchor rod supporting structure and the fiber glass reinforced plastics anchor rod are simple in structure, and reasonable in design, can increase supporting area, improve stability and reliability of supporting, and reduce occurrence of engineering accidents.

Description

technical field [0001] The invention relates to the technical field of bolt support, in particular to a fiberglass bolt support structure and a fiberglass bolt. Background technique [0002] Bolt support is widely used. At present, the anchor bolt is relatively simple to place, and a single bolt is often used for fixing. The limited force of a single bolt often leads to failure of the anchor cable, and the stability and reliability of the support are relatively low. Low, and at the same time, it is difficult for the glass fiber reinforced plastic bolt in the prior art to avoid the grout seeping out during the grouting process, which reduces the fixing effect of the bolt to a certain extent. Contents of the invention [0003] In order to solve the above problems, the present invention provides a glass fiber reinforced plastic bolt support structure with large support area, high support stability and reliability, and good grout-stopping effect, and a glass fiber reinforced p...

[0002] Bolt support is widely used. At present, the anchor bolt is relatively simple to place, and a single bolt is often used for fixing. The limited force of a single bolt often leads to failure of the anchor cable, and the stability and reliability of the support are relatively low. At the same time, it is difficult to avoid the grout leakage during the grouting process of the FRP bolt in the prior art, which reduces the fixing effect of the bolt to a certain extent
