Title:

FIRE RESISTING STRUCTURE OF COMPOSITE STRUCTURAL MEMBER FORMED BY INTEGRATING CONCRETE MEMBER AND STEEL MEMBER TOGETHER

Document Type and Number:

Japanese Patent JP2007314940

Kind Code:

A

Abstract:

To provide a fire resisting structure of a composite structural member, which is formed by integrating a concrete member and a steel member together, and to which excellent fire resistance can be imparted without deteriorating constructibility and economical efficiency.

This fire resisting structure A1 of the composite structural member A is formed by integrating the concrete member 1 and the steel member 2 together. The steel member 2 is provided with a cooling fin 3 which dissipates heat, transferred through the steel member 2 by heating during fire, into the concrete member 1. The cooling fin 3 is formed like a plate or a rod, and elongated toward the downstream side of a temperature gradient, which occurs in the heated concrete member 1, from the upstream side thereof.
