Description

TECHNICAL FIELD [0001] The present invention relates to a method for recovering and repairing damaged wooden timber structures,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood processing method, and more particularly, to a processing method for repairing and maintaining damaged wood of a wooden building.

Outdoor wood is affected by sunlight, rainstorm, air pollutants and microorganisms. Specifically, sunlight is caused by low molecular weight and discoloration of lignin component due to ultraviolet rays, rainwater is catalytic action of photo-oxidation reaction, , Peeling occurs, leaching of low-molecular-ized soluble matter, wind is supplying nutrients by soil dust transport, dropping of crushing parts, air oxidation, temperature promoting photooxidation, micro-heat generation by freezing and thawing, , Hydrolysis of cellulose by hydrolysis, microbial degradation and decay by fungus, fungus, insect pests cause deterioration such as damage of wood by insect and termite.

Wood, which is the most important part of a wooden building, is left untreated for a long time without any additional protection. It is discolored or damaged by these environmental factors, resulting in decay and loss of function. If the cracks are not properly treated, rainwater will penetrate through the crevices and cause more serious damage. In addition, recently, the climate change in the country has become severe, and the appearance of termites, which mainly live in the subtropical region, has already been seriously affected by the wood structures in the southern part.

In the case of such damage, the traditional method is to protect the discolored wood surface by grinding with a grinder or by grinding or mono-etching or rubbing, or by cutting a similar kind of wood into the cracks. However, it is the most effective method to polish the surface of wood when it is discolored by ultraviolet rays or rot fungi. However, since the damaged part of the dead bacteria must be completely changed, a lot of waste is generated, This is not only costly, but also because it does not perform post-processing properly, so the same result will be seen over time. In addition, when the crevice is inserted into the wood, the cut wood shrinks due to shrinkage of the wood. In recent years, epoxy resins have been used to replace cracks to replace them. However, even if the epoxy resin is treated, the hardened epoxy resin may lose its bonding strength for a long time and become like powder, which makes it difficult to reprocess. On the other hand, in case of insect pests, the method of completely destroying the insects is used through fumigation, but it is short-term and has no preventive function.

Therefore, in the case of traditional hanok or wooden buildings, it is difficult to treat them by the conventional methods. In some cases, wood preservative insect repellent coatings are applied instead of mono-faced or chiseled, but system for systematic restoration management has not been established so far. Korean Patent Registration No. 10-1438457 discloses a prior art document on flame retarding treatment of wood and Korean Patent Registration No. 10-0286530 discloses a prior art document on a preservation treatment method of wood products .

Further, depending on the embodiment, it may be preferable to wash within 1 hour after the decolorization of the wood and the removal of the soil-decontamination agent.

In addition, parts of the wood which are damaged by ultraviolet rays and which are severely discolored can be ground using an electric sander.

Step S200 is a step of performing preservation treatment on the wood part recovered in step S100. At this time, the preservation treatment can be performed only when the surface moisture of the wood part is dried to 20% or less. More specifically, if the surface humidity exceeds 20% or the relative humidity exceeds 60%, step S200 may not be performed. At this time, the surface moisture of the wood can be measured using an electronic surface hygrometer.

In this step S200, the wood preservative is applied to the wood to be preserved. At this time, the wood preservative is an environment-friendly water-soluble wood preservative containing propiconazole as a constituent when the wood is an indoor wood, Is an outdoor wood, it is preferable to use an oily material containing propiconazole, 3-iodo-2-propenyl butan carbamate, and cypermethrin as a constituent, It may be a wood preservative. Here, the wood preservative can be applied so as to be sufficiently absorbed into the wood by using the sprayer, the roller and the brush. Depending on the embodiment, an electric atomizer may be used.

Also, in the case of applying the wood preservative, the coating may be applied two to three times, and the waiting time between the coatings may be from 24 hours to 48 hours. That is, after the wood preservative is applied and dried for 24 to 48 hours, the wood preservative can be applied again and dried for 24 to 48 hours. As described above, depending on the embodiment, it may be preferable to paint twice.

On the other hand, propiconazole, which is included in the wood preservative as a constituent component, sterilizes dead bacteria and can prevent the generation of long-term microorganisms, and 3-iodo-2-propenylbutanecarbamate (3-Iode -2-propenyl butan carbamate) works in a short period of time but has a very high bactericidal effect. Cypermethrin, as an insecticide, can kill long-term larvae and termites in woods and show long-term preventive effects.

Step S300 is a step of cutting the cracks of the wood with a wood plug. At this time, as the wood plug, products containing 65 to 75% of barium sulfate can be used. Also, the deep part of the crevice can be covered a plurality of times, and finally, when the burr part is dried, it can be sanded and finished.

Step S400 is a step of finally preserving the state of the wood so that the anticorrosion paint is finally applied to the wood to be maintained for a long period of time. At this time, if the wood through the process up to the step S300 is dried, the wood anticorrosive paint is painted, and the paint is applied when the surface moisture of the wood is dried to 20% or less. That is, more specifically, if the surface humidity exceeds 20% or the relative humidity exceeds 60%, step S400 may not be performed. Also, the surface moisture of the wood can be measured using an electronic surface hygrometer.

On the other hand, the wood anticorrosive paint used in step S400 is a first wood anticorrosive paint containing 30 to 40% of Alkyd resin and a second wood containing 40 to 50% of Alkyd resin Anticorrosion paints. Details of step S400 will be described in detail with reference to FIG.

FIG. 2 is a view showing a flow of a processing method for recovering and maintaining damaged wood of a wooden building according to another embodiment of the present invention. As shown in FIG. 2, according to another embodiment of the present invention, when the surface moisture of the wood repaired in step S300 is dried to 20% or less, the first wood antiseptic paint is applied to the wood, (S410) drying the wood for 12 hours (S410), applying a second wood anticorrosive paint to the dried wood in step S410 and drying the wood for a minimum of 12 hours (S420), and drying the second wood antifouling paint And applying (S430) drying the coating for at least 12 hours.

The concrete structures of the first wood anticorrosive paint and the second wood anticorrosive paint of steps S410 through S430 are as described in detail with reference to FIG. 1, and the description thereof will be omitted. Further, the first wood antiseptic and second wood antifouling paints used in steps S410 to S430 may be applied by using an atomizer, a roller and a brush, and in some embodiments, an electric atomizer may be used.

More specifically, step S410 is a step of applying and drying the first wood anticorrosive paint when the surface moisture of the wood repaired in step S300 is dried. At this time, the first wood anticorrosive coating material is an ultraviolet screening agent Or more.

On the other hand, in applying and drying the first wood antiseptic paint, it may be dried for at least 12 hours, and depending on the embodiment, it may be desirable to dry as long as possible. However, more specifically, it may be dried for at least 12 hours and at most 36 hours.
