Novel fireproof plugging structure for civil air defense engineering

Abstract

The invention discloses a novel fireproof plugging structure for civil air defense engineering, belongs to the technical field of fireproof plugging structures, and aims to solve the problem that oncean existing fireproof plugging structure at a pipeline continuously bears a high temperature of more than 300 DEG C, a load gradual losing effect is achieved, and smoke leakage is caused. An engineering pipeline is fixedly mounted in a heat-insulation fireproof curtain wall, a fireproof plugging mechanism is fixedly mounted at the joint of the engineering pipeline and the heat-insulation fireproof curtain wall, and an outer elastic fireproof sealant is arranged at the joint of the outer wall of the fireproof plugging mechanism and the heat-insulation fireproof curtain wall; an inner elastic fireproof sealant is arranged at the joint of the inner wall of the fireproof plugging mechanism and the heat-insulation fireproof curtain wall, a ceramic heat-resisting ring is arranged in the fireproof plugging mechanism and fixedly connected with the inner wall of the fireproof plugging mechanism through the inner elastic fireproof sealant, and air holes are formed in the ceramic heat-resistingring; and the plurality of air holes are formed.

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
