Problems solved by technology

[0003] Most of the existing tunnel flue panels are made of concrete materials. This type of flue panel has the following problems: 1. Due to the limitations of its structure and material, the concrete flue panel will crack under continuous high temperature, so there will be sundries Falling from the top of the tunnel, or even a collapse accident; 2. If the vehicle in the tunnel explodes, the flue plate of the concrete structure will have gravel splashing, causing a secondary accident; 3. The fire protection level of concrete is low

Abstract

The invention relates to a tunnel flue plate. The tunnel flue plate comprises a plate body, the plate body is of a hollow structure, the upper surface and the lower surface of the plate body are provided with dovetail grooves, and fireproof coating is arranged on the upper surface and the lower surface of the plate body; the plate body is formed by compounding a fiber material, a resin material and an auxiliary agent. A manufacturing process of the tunnel flue plate comprises the following steps of 1, yarn arrangement and connection of the fiber material; 2, fiber impregnation; 3, preforming and solidification; 4, cooling; 5, drawing; 6, cutting; 7, arrangement of the fireproof coating. The tunnel flue plate has the advantages of good fireproofness, high strength, low weight and convenientinstallation, wherein the fireproofness reaches the A2 fireproof grade; the phenomena such as high-temperature cracking, explosion splashing and the like of concrete does not occur; collapse accidents do not occur.

Description

technical field [0001] The invention relates to a tunnel flue plate. It belongs to the field of mechanical technology. Background technique [0002] The interior of the tunnel is narrow and long, coupled with its unique closed structure on both sides, it is difficult to evacuate vehicles and people on board. In the event of a fire, the high-temperature smoke has a long flow path in the tunnel, causing heavy losses. Among them, the flue plate structure under the centralized smoke exhaust mode is an important structure to improve personnel safety in case of fire. [0003] Most of the existing tunnel flue panels are made of concrete materials. This type of flue panel has the following problems: 1. Due to the limitations of its structure and material, the concrete flue panel will crack under continuous high temperature, so there will be sundries Falling from the top of the tunnel, or even a collapse accident; 2. If the vehicle in the tunnel explodes, the flue slab of the concr...
