Fire-proof sealing structure in curtain wall interlayers designed based on raised flooring and construction method thereof

Abstract

The invention discloses a fire-proof sealing structure in curtain wall interlayers designed based on raised flooring and a construction method thereof. The structure comprises a curtain connecting piece fixed in the edge of the floor slab, an upper keel sealing structure and a lower keel sealing structure which are disposed on the upper position and the lower position of the floor slab respectively, and an interlayer sealing structure. The upper keel sealing structure and the lower keel sealing structure are both arranged along the edge of the floor slab. The upper keel sealing structure and the lower keel sealing structure both comprise keel frames, the rock wool filling the keel frames, and the fire-proof plates fixed in both sides of the keel frames. The keel frames comprise the horizontal fixing keels fixed in the surface of the floor slab directly, the vertical keels fixed vertically in the horizontal fixing keels, and the horizontal supporting keels fixed in the other end of the vertical keels. The interlayer sealing structure comprises the sealing rock wool for filling gaps and the sealing layers for fixing the sealing rock wool. The sealing rock wool fills the gaps between the upper keel sealing structure and the curtain wall and between the floor slab and the curtain wall. The fire-proof sealing structure in curtain wall layers designed based on raised flooring and the construction method thereof have the advantages of being convenient and fast in construction, high in the airtight property of fire-proof sealing structure, and convenient in future curtain wall maintenance.

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...
