Design method of BFRP bar anti-floating anchor rod

Abstract

The invention discloses a design method of a BFRP bar anti-floating anchor rod, and relates to the field of construction engineering. The problems that a rebar serving as a bar of an anti-floating anchor rod is tedious in manufacturing and cannot be used in the corrosion-resistant environment, or the construction procedure and the engineering construction cost are increased due to the addition ofanti-corrosion measures are solved. According to the key points of the technical scheme, the design method comprises the following steps that firstly, the length and the sectional area of a rebar rodof the rebar anti-floating anchor rod are calculated; then, according to the equal strength and equal stiffness conversion principle, the sectional area of a rebar body of the rebar is converted intothe sectional area of BFRP bar bodies; then the diameter and the number of the BFRP bar bodies are calculated; then, the BFRP bar bodies are subjected to fixed-size clipping through a bar cutting machine, and then BFRP composite materials are machined to form the BFRP bar bodies. The design method has the effects that the anti-floating anchor rod has extremely high acid resistance and extremely high alkali resistance, thus corrosion of rebar rod materials used in the harsh environment can be prevented, and the anti-floating durability of a building and the construction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, more specifically, it relates to a design method of a BFRP reinforcement anti-floating anchor rod. Background technique [0002] Anchor is the most basic component of geotechnical engineering support. At present, anchor rods are not only used in mines, but also in engineering technology for main body reinforcement of slopes, tunnels and dams. As a tensile member that goes deep into the ground, the bolt is connected to the engineering structure at one end, and the other end goes deep into the ground. The whole bolt is divided into a free section and an anchor section. area, its function is to apply prestress to the anchor rod; the anchor section refers to the area where the cement slurry bonds the prestressed tendons to the soil layer, and its function is to increase the bonding friction between the anchor body and the soil layer, increasing The pressure-bearing effect of the an...

AI Technical Summary

Problems solved by technology

[0004] The anti-floating anchor rods in the prior art all use steel bars as their reinforcements, which are not only cumbersome to manufacture, but also do not have the conditions for use in corrosion-resistant environments, or increase the construction process and project cost due to the addition of anti-corrosion measures, which does not conform to the national energy-saving policy
