Seal assembly for sandwich panel of building curtain wall

The utility model relates to a seal assembly for a sandwich panel of a building curtain wall. The seal assembly for the sandwich panel of the building curtain wall comprises a rubber strip and a heat-insulation material and is arranged in a transverse connection gap of the sandwich panel of the building curtain wall, wherein the rubber strip is positioned on the outer side of the gap; the heat-insulation material is positioned on the inner side of the gap; the rubber strip consists of a left portion and a right portion which are symmetric; each of the left portion and the right portion comprises four elongated oblique rubber strip bodies; and the oblique rubber strip bodies are tightly adhered to folded edges of the sandwich panel of the building curtain wall. After the rubber strip is formed, the two symmetric portions of the rubber strip are positioned on the same horizontal line. The heat-insulation material is a foam bar or a rock wool strip. The seal assembly for the sandwich panel of the building curtain wall has the advantages that the rubber strip of the seal assembly is tightly adhered to the folded edges of the sandwich panel of the building curtain wall due to effects of tension, and can automatically deform along with slight change of the gap, and the gas tightness, the water tightness and the wind-resistant performance of a curtain wall system are improved.
