Pull-out test device of glass fiber rib anti-floating anchor and test method of pull-out test device

Abstract

The invention relates to the technical field of anti-floating anchors of construction foundation projects, in particular to a pull-out test device of a glass fiber rib anti-floating anchor and a test method of the pull-out test device. The pull-out test device comprises a base, a center hole jack and an anchoring clamp. An anchor body sequentially penetrates through the base and the center hole jack from bottom to top. The top end of the anchor body is fixedly connected with the anchoring clamp. The jack is supported between the base and the anchoring clamp. When the anchoring clamp is ejected by the jack, the anchor body can be loaded. A dial indicator is arranged above the anchor body. The height of the dial indicator is set in an adjustable and fixed mode. A pointer head of the dial indicator is ejected on the top end face of the anchor rod. The pull-out test device is simple in structure, the glass fiber rib anti-floating anchor can be effectively anchored through the anchoring clamp, existing glue anchoring is replaced, the clamp can be repeatedly used, the glass fiber rib anti-floating anchor is convenient and rapid to use, the test time is effectively shortened, materials are saved, the test cost is reduced, and the anchor is not damaged.

Description

technical field [0001] The invention relates to the technical field of anti-floating anchor rods in building foundation engineering, in particular to a pull-out test device and a test method for glass fiber reinforcement anti-floating anchor rods. Background technique [0002] With the continuous development and utilization of underground space, the buried depth of the foundation of the building continues to increase, and the problem of anti-floating has become more and more prominent. The general anti-floating technical measures include groundwater reduction, ballast method, anti-floating piles and anti-floating anchors. pole etc. Among them, the mechanism of the anti-floating anchor is to use the tensile force generated by the tensile strength of the anchor itself and the pull-out force generated by the friction between the anchor and the rock-soil layer to restrain the floating trend of the building foundation floor. , so that the friction force of the anchor rod is grea...

AI Technical Summary

Problems solved by technology

Most of the anti-floating anchor rods are made of metal materials. After they are buried in a stable rock mass soil layer, as time goes on, the rod body material is easy to corrode, which affects the strength of the anchor rod body, and then destroys its anchoring effect. This phenomenon It is particularly prominent in the anti-floating aspect of the foundation of buildings (structures) in coastal areas.
