CONNECTION STRUCTURE BETWEEN WOODEN MATERIAL AND STEEL MATERIAL
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
【課題】木質材と鉄骨材の接合部が１時間の火災加熱（ＩＳＯ８３４に規定される標準加熱温度時間曲線）を受けた場合であっても、鉄骨材に接触・接合する部分の木質材の芯材の温度を２６０℃以下、より好ましくは２００℃以下に抑えることを可能にし、優れた耐火性能を発揮する木質材と鉄骨材の接合部構造を提供する。【解決手段】木質材１と鉄骨材２の接合部の構造Ａであって、耐火被覆４を施して鉄骨材２の周囲に耐火被覆層（４）を形成するとともに、鉄骨材２の木質材１側に、鉄骨材２の他の部分の一般部６よりも耐火被覆層（４）の厚さｔを大にした増し厚部７を設けて構成する。【選択図】図１
