A method for fire protection of wooden structural members

Abstract

The invention relates to a method for fire protection of wooden structural components, comprising the following steps: S1, performing surface treatment on the wooden components, removing sundries on the surface of the components, grinding the working surface and dusting off the generated sawdust; S2, decorating the working surface One layer of anti-corrosion paint; S3. After the anti-corrosion paint is completely dry, apply the first layer of ash, and scrape it to make it smooth; Lay a layer of sackcloth evenly on the first layer of ash, and roll the fluffy part with a board; S5, apply the second layer of ash; the second layer of ash is made of anti-corrosion paint, gypsum powder and tile ash in a ratio of 1:1 : 1 prepared; S6, stand still, apply primer after the ashes are dry; S7, apply topcoat the next day. The invention obviously improves the fire resistance performance of the wooden structure components, improves the fireproof safety performance of the wooden structure building; adopts the inorganic ash material, reduces the cost, is simple and convenient in construction, has fewer steps, is economical and reasonable, and is effective.

Description

technical field [0001] The invention relates to a method for fire protection of wooden structural components, belonging to the technical field of civil engineering. Background technique [0002] There are many traditional wooden structures with a long history left in our country, most of which are important historical and cultural heritages in our country. Because wood is a combustible material, the fire load in traditional wooden structure buildings is large, and after thousands of years of wind and sun, the wood is dehydrated to form "dry firewood", which is very easy to be ignited. Therefore, the fire risk of traditional wooden structure buildings is very high. , it is necessary to adopt fire protection methods to improve the fire resistance of wooden structural members. The surface of wooden beams and wooden columns in traditional palace buildings and temple buildings is usually treated with ground wares. The typical ground wares manufacturing process includes one hemp ...

Problems solved by technology

The commonly used method of spraying fire-resistant and flame-retardant coatings can only improve the combustion performance of wood, and has very limited improvement in the fire resistance limit.
