Study on the pull-out mechanical properties of the new type of thermal insulation wallboard connector of GFRP fiber composites

In order to discuss the pull-out mechanical properties of the new connectors of GFRP thermal insulation exterior wall panels, the research was carried out by means of field tests and numerical model calculations. The specific conclusions are as follows: (1) The experimental results and numerical analysis results show that the tensile bearing capacity of the new connector of GFRP fiber composites is 2~3 times of the standard value. (2) The position of the maximum deformation and the maximum tensile force of the connecting piece obtained through the analysis in the numerical simulation are both located at the connecting end of the connecting piece. (3) The maximum tensile strength obtained from the experimental results of this performance study and the numerical simulation results are similar, and the deformation laws basically match.
