Abstract

The invention discloses a fireproof plate for a tunnel and further discloses a mounting structure and construction method of the fireproof plate for the tunnel. A top plate body at least comprises the following raw material components of, by mass, 3.5%-5% of timber, 3%-5.5% of cement bags, 32%-45% of quartz powder, 22%-32% of cement, 10%-20% of calcium hydroxide, 3%-5% of aluminium hydroxide and 0.5%-1% of bentonite; a side wall fireproof plate body at least comprises the following raw material components of, by mass, 4%-5.5% of timber, 2%-3.5% of cement bags, 40%-55% of quartz powder, 30%-45% of cement, 2%-4% of aluminium hydroxide and 0.6%-1.2% of bentonite. The fireproof plate adopting the material components is good in flame retarding effect, high in product strength and good in toughness and bending resistant performance. The fireproof security level of the tunnel is effectively promoted, and the sound absorption and noise reduction effects and the visual effect are all better.

Description

technical field [0001] The invention relates to a tunnel fireproof board. Background technique [0002] The inner surface of the road tunnel is generally a concrete structure, which requires fireproofing treatment. At present, the fireproofing treatment on the top surface of the tunnel is sprayed with fireproofing paint, and the fireproofing and heat insulation effect is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fireproof board component, installation structure and construction method with unique structure and good fireproof and heat insulation effect. [0004] In order to solve the above technical problems, a fireproof board for tunnels according to the present invention includes a top fireproof board and a side wall fireproof board; the composition of the raw material of the top board contains at least the following substances in mass percentage: 3.5% to 5% of wood; Cement bag 3-5.5%; quartz...
