PROBLEM TO BE SOLVED: To provide a connection structure between a wooden material and a steel material that keeps a temperature of a core material of the wooden material, at a portion contacting and connected to the steel material, to 260°C or less, or preferably to 200°C or less, even when the connection between the wooden material and the steel material is exposed to one hour of heating by fire (a standard heating temperature-time curve as provided by the ISO 834).SOLUTION: A structure A of a connection between a wooden material 1 and a steel material 2 has a fire-resistant coating layer (4) formed over the steel material 2 by providing a fire-resistant coating 4, and a thickness-increased part 7 formed on a wooden material 1 side of the steel material 2 that has an increased thickness t of the fire-resistant coating layer (4) than a general part 6 at other parts of the steel material 2.SELECTED DRAWING: Figure 1 |
