A fireproof sealing structure for civil air defense engineering

Abstract

The invention discloses a fireproof sealing structure for civil air defense engineering, which belongs to the technical field of fireproof sealing structure, in order to solve the problem that once the existing fireproof sealing structure at the pipeline continuously bears a high temperature above 300 degrees Celsius, the load will gradually lose its effect , leading to the problem of smoke leakage. Engineering pipelines are fixedly installed inside the heat-insulating and fire-proof curtain wall, and a fire-proof sealing mechanism is fixedly installed at the connection between the engineering pipeline and the heat-insulating and fire-proof curtain wall, and the joint between the outer wall of the fire-proof sealing mechanism and the heat-insulating and fire-proof curtain wall An outer elastic fireproof sealant is provided, and an inner elastic fireproof sealant is provided at the joint between the inner wall of the fireproof sealing mechanism and the heat-insulating fireproof curtain wall, and a ceramic heat-resistant ring is arranged inside the fireproof sealing mechanism, and the ceramic heat-resistant The ring is fixedly connected with the inner wall of the fireproof sealing mechanism through the inner elastic fireproof sealant, and the inside of the ceramic heat-resistant ring is provided with vent holes, and several vent holes are provided.

Description

technical field [0001] The invention belongs to the technical field of fireproof sealing structures, in particular to a novel fireproof sealing structure for civil air defense projects. Background technique [0002] In the field of construction, a firewall refers to a non-combustible wall that prevents fire from spreading to adjacent areas and has a fire resistance rating of not less than three hours. It is used to divide fire compartments or prevent fires from spreading between buildings. When passing pipes and cables inside the firewall, it is usually necessary to adopt fireproof sealing technology to prevent the fire from spreading to the other side of the firewall. Fireproof sealing, used to seal various penetrations, such as various openings formed when cables, air ducts, oil pipes, air pipes, etc. pass through walls (warehouses) walls and floor (A) panels, as well as fire separation of cable bridges, so as to avoid The fire spread through these openings and gaps.

Problems solved by technology

[0003] Once the existing fire-proof sealing structure at the pipe continues to withstand high temperatures above 300 degrees Celsius, it will reach the load and gradually lose its effect, resulting in smoke leakage. Therefore, a new type of fire-proof sealing structure for civil air defense projects is urgently needed in the market to solve these problems
