AI Technical Summary

Technical Problem

In existing technologies, the spacing of fixing nails during TRC reinforcement construction is unreasonable, which leads to unstable bonding between the carbon fiber mesh and the fiber-reinforced cementitious material slurry, making it prone to detachment and delaying the construction period.

Method used

By constructing a deflection curve model and calculating the spacing of the fixing nails based on field parameters, the carbon fiber mesh is ensured not to fall off under extreme conditions. This includes obtaining field parameters, constructing a deflection curve model, calculating the size of the mesh after elongation, and the spacing of the fixing nails.

Benefits of technology

The calculated spacing of the fixing nails can prevent the carbon fiber mesh from falling off under extreme conditions, reduce the number of fixing nails, and save construction costs and construction time.

Abstract

This invention proposes a method for calculating the spacing of fixing nails during TRC reinforcement construction, including: obtaining on-site parameters during TRC reinforcement construction; constructing a deflection curve model of the fixing nail spacing based on preset conditions and the on-site parameters; obtaining the elongated size of the carbon fiber mesh at the fixing nails under uniformly distributed load based on the deflection curve model; wherein the elongated size of the mesh is not greater than the diameter of the disk at the end of the fixing nail; and obtaining the fixing nail spacing based on the elongated size of the mesh. This invention can calculate the fixing nail spacing under extreme conditions to ensure that the carbon fiber mesh and fiber-reinforced cementitious material slurry do not detach, meeting the construction requirements in most cases. The spacing calculated using the method of this invention is relatively large, which can reduce the number of fixing nails to be placed on-site, greatly saving construction costs and construction time.
