An encapsulation structure for exposed guide rails of fireproof shutter doors

Abstract

The invention discloses a packaging structure of exposed guide rails of a fireproof roller shutter door. The packaging structure comprises angle steel pieces, fireproof rock wool plates, vertical supporting columns, transverse supporting columns and fireproof rock wool layers. A wing panel on one side of each angle steel piece is used for being fixed to the corresponding guide rail of the shutter door. A wing panel on the other side of each angle steel piece is used for being fixed to a fireproof partition wall through an anchor bolt. One ends of the transverse supporting columns are vertically installed on the vertical supporting columns to form whole racks. The left side and the right side of the guide rails are each provided with one whole rack. The other ends of the transverse supporting columns of the whole supports are vertically installed on the fireproof partition wall so that the vertical supporting columns are vertically arranged and are parallel to the fireproof partition wall. The fireproof rock wool plates are fixed to the vertical supporting columns in a covering mode and flush with the exposed edges of the guide rails. The fireproof rock wool layers are arranged in gaps between the fireproof rock wool plates and the fireproof partition wall. The packaging structure can effectively package the exposed guide rails, has good fireproof sealing performance and has good application prospects.

Description

technical field [0001] The invention relates to a fireproof encapsulation structure, in particular to an encapsulation structure for exposed guide rails of fireproof rolling doors. Background technique [0002] The fireproof shutter door and the fireproof partition wall are connected together as the boundary of the fire protection partition of the building. At present, the double-connected double-guide fireproof shutter door is widely used in the market. Partition walls and exposed guide rails not only affect the aesthetics of the building, but also always become obstacles in the acceptance of fire protection. [0003] The conventional process for dealing with the exposed guide rail is to enclose the guide rail with bricks after the guide rail is fixed on the fire partition wall. However, the cross-sectional size of the guide rail is small and the height is high. The stability of the wall connection, and the masonry surface under different conditions are prone to cracking a...
