| 摘要 |
The present invention relates to a sandwich panel binding structure to which a fireproof foaming adhesive composition or a foaming adhesive pad is bound, wherein the fireproof foaming adhesive composition or foaming adhesive pad includes a resin adhesive composition containing particles and polymers and is formed in the shape of a pad having a thickness of 1-5 mm and inserted into the connection site between convex portions and concave portions of the sandwich panel so that in case of fire, the fireproof foaming adhesive composition or pad is foamed by heat and thereby effectively seals any space in an assembly unit which is the connection site. Accordingly, the present invention can effectively prevent flames from spreading or moving through the gaps that may be present in a panel assembly unit, and can enhance the durability (for example, compression strength) to be sufficient for the performance of a fireproof structure through polymers contained in the fireproof foaming adhesive composition or foaming adhesive pad. |
