Abstract

The invention discloses a curtain wall interlayer fireproof sealing structure based on raised floor design and a construction method thereof. The present invention includes curtain wall connectors fixed on the edge of the floor slab, the sealing structure on the keel, the sealing structure under the keel and the interlayer sealing structure respectively arranged above and below the floor; the sealing structure on the keel and the sealing structure under the keel are both It is arranged along the edge of the floor, including joist frames, rock wool filled in the joist frames and fireproof boards fixed on both sides of the joist frames. The joist frames include horizontal fixed joists directly fixed on the surface of the floor, vertically fixed on the horizontal The vertical keel and the horizontal support keel fixed at the other end of the vertical keel; the interlayer sealing structure includes the sealing rock wool for filling the gap and the sealing layer for fixing the rock wool, and the sealing rock wool is filled on the keel to seal Between the structure and the curtain wall and between the floor and the curtain wall. The invention has the advantages of convenient construction, high fireproof sealing and airtightness, and is convenient for maintenance of the curtain wall in the later stage.

Description

technical field [0001] The invention relates to the technical field of fireproof sealing structure between curtain wall layers, in particular to a fireproof sealing structure between curtain wall layers based on raised floor design and a construction method thereof. Background technique [0002] In order to pursue the beauty of the appearance and the safety of fire prevention, the current high-rise buildings often use the unit glass curtain wall as the main external structure of the building. Generally, there is no window sill wall. The fire can easily spread to the whole building along the interstory seam, so the fireproof sealing of the interstory seam is particularly important. [0003] For the curtain wall structure designed for internal raised floors, the fireproof seal between curtain wall layers is usually located in the area above the floor below the raised floor. At present, the common methods of fireproof sealing mainly include the following: one is to use brick w...
