Description
Technical Field
The invention relates to a method for protecting a wood structural member from fire, and belongs to the technical field of civil engineering.
background
Most of the traditional wooden structure buildings with more and long-standing histories are important historical heritages in China. Because the wood is a combustible material, the fire load in the traditional wood structure building is large, and after thousands of years of wind and sunshine, the wood is dehydrated to form dry wood which is easy to ignite, so that the fire risk of the traditional wood structure building is great, a fire protection method is required to be adopted, and the fire resistance of the wood structure component is improved. The surfaces of wooden beams and wooden column members in the traditional palace buildings and temple buildings are usually processed by adopting the plaster, and the manufacturing process of the plaster typically comprises the processes of five ashes, four ashes, six ashes, and the like, and is mainly formed by mixing organic matters and inorganic matters such as brick ash, blood materials, lime, flour, raw tung oil, and the like. However, materials such as oil, blood and the like need to be decocted on site, and the ground layer process has more construction procedures and more complex construction process.
the wood structure building has the advantages of simple construction, short construction period, energy conservation, environmental protection, good earthquake resistance and the like, and the modern wood structure gets more and more attention and development in China along with the development of the fast growing technology of the wood and the increase of the quantity of imported wood. The existing wood structure building is high in height, and the fire endurance requirement of the wood structure member is high. The common method for spraying fireproof flame-retardant coating can only improve the combustion performance of wood, and has very limited improvement on the fire resistance limit.
Therefore, a new method is required to simply and effectively improve the fire resistance of the wood structural member.
Disclosure of Invention

The invention adopts the following technical scheme:
A method for protecting a wood structural member from fire includes S1, performing surface treatment on the wood structural member 1, removing impurities on the surface of the member, polishing a working surface and removing generated wood chips by dusting; s2, coating a layer of anticorrosive paint 2 on the working surface; s3, after the anticorrosive paint is completely dried, coating a first layer of ash 3, and leveling and decorating; the first layer of ash 3 is prepared from anticorrosive paint and gypsum powder according to the mass ratio of 1: 1; s4, uniformly paving a layer of linen 4 on the first layer of ash 3, and rolling and pressing the fluffy part by using a plate; s5, coating a second layer of ash 5; the second layer of ash 5 is prepared from anticorrosive paint, gypsum powder and tile ash according to the mass ratio of 1:1: 1; s6, standing for several days, and after the ash materials are completely dried, operating the primer 6; and S7, finishing the top coat 7 the next day after finishing the priming.
Preferably, the anticorrosive paint 2 is a self-drying liquid coating prepared by diluting natural raw lacquer harvested from a lacquer tree with an organic solvent after cleaning, filtering, dehydrating, activating and oxidative polymerizing.
Preferably, the primer 6 is prepared from anticorrosive paint, iron oxide red powder and a diluent according to the mass ratio of 2:1: 1.
Preferably, the finish paint 7 is prepared from anticorrosive paint and tung oil according to the mass ratio of 1: 1.
Preferably, the surface of the primer 6 and the surface of the finish paint 7 is smooth and clean after being coated, and no wrinkles are left.
the invention has the beneficial effects that:
1) the method can delay the carbonization time of the wood, reduce the carbonization speed of the wood, obviously improve the fire resistance of the wood structural member and improve the fire safety performance of the wood structural building;
2) The method adopts inorganic ash, is convenient to construct, economic, reasonable and effective.
3) The first layer of ash material is prepared from anticorrosive paint and gypsum powder according to the mass ratio of 1:1, the second layer of ash material is prepared from anticorrosive paint, gypsum powder and tile ash according to the mass ratio of 1:1:1, both the fireproof performance and the firmness are considered, and the design is ingenious.
