Fire-resistant reinforcement structure, fire-resistant reinforcement architectural member, fire-resistant reinforcement method for architectural member

摘要

[Problem] To provide a fire-resistant reinforcement structure which facilitates work for improving fire resistance of architectural members such as pipes, a door, and a sash, a fire-resistant reinforcement architectural member, and a fire-resistant reinforcement method for an architectural member. [Solution] A fire-resistant reinforcement structure is formed by pouring a thermally expandable fire-resistant material into a gap in and/or the interior of an architectural member, and characterized in that the viscosity of the thermally expandable heat-resistant material at 25°C before the thermally expandable fire-resistant material is poured into the gap in and/or the interior of the architectural member is in the range of 1000-100000 mPa·s, and the thermally expandable fire-resistant material loses fluidity at 25°C after being poured into the gap in and/or the interior of the architectural member.
