Track traversing fireproof rolling shutter and construction method thereof

Abstract

The invention provides a track traversing fireproof rolling shutter and a construction method of the track traversing fireproof rolling shutter. The fireproof rolling shutter comprises a fireproof rolling shutter door arranged at a passing hole formed in a fireproof barrier and a threshold arranged on the ground under the fireproof rolling shutter door; and a notch corresponding to the passing width of a transportation tool is formed in the position, traversed by the track, of the threshold, and fireproof expansion sealing strips are arranged in the notch. According to the track traversing fireproof rolling shutter and the construction method, the threshold is additionally arranged on the gourd under the fireproof shutter door, the notch corresponding to the passing width of the transportation tool is formed in the position, traversed by the track, of the threshold, and the fireproof expansion sealing strips are arranged in the notch, so that the passing width of the track transportation is limited within the expansion range of the fireproof expansion sealing strips, meanwhile the effective supplement is provided for the fireproof sealing performance of the fireproof rolling shutter door, the fireproof limit requirement of the fireproof barrier is met, and the fireproof, heat-insulating and smoke-isolating requirements are met.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a rail-passing fireproof shutter and a construction method for a rail-passing fireproof shutter. Background technique [0002] In spent fuel reprocessing facilities, the transfer of product containers between workshops often relies on transfer trolleys, and the transfer of spent fuel shielding containers often uses train transportation. Both of these transportation methods need to be realized by rail, and rail The laying usually needs to pass through the fire compartment or factory building. At present, in the "Code for Fire Protection of Building Design" GB50016-2014 (2018 Edition), it is clearly stipulated that a 3h firewall should be set up as a barrier between adjacent factory buildings or between adjacent fire compartments. When the fire barrier is used, it is usually necessary to set a 3h (that is, the fire resistance limit is not less than 3 hours) fire shutte...

AI Technical Summary

Problems solved by technology

However, in the actual operation process, due to the traffic requirements of the bottom rail, the fireproof and smoke-proof airtightness requirements of the fire barrier cannot be met at the contact part of the fire shutter and the ground, resulting in the fire shutter cannot be completely sealed with the ground, and the fire barrier is not complete. It cannot meet the specification requirements of 3h fire barrier
