| Περίληψη: | Purpose: In this study, a high-precision inversion method based on field test data to determine the equivalent convection coefficient of a concrete surface was employed when employing the steel–polyurethane composite. Design/methodology/approach: The research method of this article is as follows: (1) Design experiments to measure the temperature inside the concrete block when using steel polyurethane composite formwork; (2) Using temperature field reconstruction technology to invert the equivalent thermal convection coefficient of structural surfaces; (3) Prove that the surface temperature distribution of the structure is uniform; (4) Obtain a numerical simulation method for solving the equivalent thermal convection coefficient of concrete when using steel polyurethane composite formwork. Findings: By analyzing the insulation field test results for the steel–polyurethane composite, two conclusions can be drawn: first, even if the steel groove is large and its wall thickness is very thin, concrete heat is dissipated primarily via the steel groove; and second, the unfilled area of the steel groove can be coated with a thin polyurethane layer, which can have a significant impact on the heat dissipation of the concrete, and the degree of this impact can be quantified. Based on the results, a finite element calculation method is proposed to calculate the equivalent convection coefficient of the concrete surface when employing a steel–polyurethane composite. Originality/value: The proposed method can simulate and determine the equivalent convection coefficient of the concrete surface when steel grooves of any dimension are sprayed with polyurethane of any thickness.
