1 The scientific research proved that:the life-span of people who
live in log made houses is 9 to 10 years longer! |
The life is more and more precious.Today, people not only request health body and spirit, moreover request health living space.Log house can satisfy the people who pursue the high quality life and good health.
Overseas research organization specially is engaged in the human body natural sciences investigation indicate that, the life-span of people who live in log made houses is 9 to 11 years longer than people who live in ferroconcrete made houses!
Log house is the true environmental protection construction in the world. Chinese forestry teaching material "Lumber Protection Study" also elaorated the thesis that the life-span of people who live in log made houses is 9 to 11 years longer.(read "Lumber Protection Study" on 16th page of 12th line). The reason is as follows:
1.The fragrance multi- essences and the anoin (air vitamin) in Log house compares the ferrocondrete made house to outdo dozens of times to hundreds of times.The fragrance multi- essences and the anoin are the substance which the modern forest bathing penson like, they can kill the bacterium in the air, restrain the human disease,amplify immunity.
2 .Compareing identical biology under the wooden environment and the concrete environment , its difference is approximately 42% in immunity,generating and so on.Former is the modern humanity's best existing space.
3.The lumber can absorb the ultraviolet ray in the sunlight,reduces injury of the ultraviolet ray to the human body,simultaneously it can reflect the infrared.The lumber is the porous material,its surface forms small concave-convex which can become the reflex phenomenon or absorb partial lights,so the dizziness light can become gentle.Therefore, the log house stimulates to person's visual slightly.
4.The lumber has the function for adjusting the room temperature.It can bring people the warm feeling in winter,this is other building materials is unable to compare.Adjustment humidity is one of peculiarities,log house can alleviates the humidity change by its peculiaritiy. The research indicated that log made house is lower than ferroconcrete made house 8% to 10% on average humidity per year and Range of variation remain 60% to 80%.It most approaches with the best environment target that the relative humidity 60% about .
5.The log house has strong quakeproof capability.The mass of houses survived fortunately were log made houses in 1995 Japanese Kobe big earthquake. The Russia type log houses that are constructed by the log materials has the unique wooden dent channel,the structure is stable ,so the log houses have strong quakeproof capability.
In summary, the log house has many meritssuch as durable and corrosion preventing,it will be the best choice for people environment to reside. |
| 2 Log houses can breathe |
The log house can breathe,certainly it's not likely the animal's breath,it
refers to the lumber's characteristic in adjusting temperature and humidity.
The lumber is one kind of porous material,the thermal conductivity is
smaller and is not good conductor.The structure of lumber interior is similar to
sponge, it can absorb or discharges the moisture according to the environment
humidity change, thus adjust the temperature and the humidityof log house. The
lumber is the natural material and it is similar to a natural air conditioner.The
log house is like as if identical natural air conditionerWhen the humidity is
high,log house can automatically absorb moisture.And it can emit the moisture
from its cell when dry.American New York country laboratory research proved that
in the world it only can be called the green environmental protection log house,
it can conserve energy 50% compare with the ferroconcrete made houses.
It's well known that the trees exhale the oxygen and absorb carbon dioxide,
which is opposite to the human being.Therefor, the trees are the human friends,
and the log houses are oxygen bar. |
| 3 The log houses'development cannot destroy the ecological environment. |
The healthy ecology environmental protection log house is the outstanding product which the forest resources contribute for the humanity.
The lumber is renewable resources. It won't be able to destroy the ecological environment and can lead the forest activeness if we suitably use the lumber. Therefore, using the lumber material for the residence environment can improve people's residence quality, leaves behind happier space for the descendants.
The forest resources are one kind of renewable resources.So the good management plan may enable this global most precious resources to circulate,and the resources will continue to provides the help for the human being. |
| 4 The log houses can prevent burning and moisture. |
According to the technical service department of American forest product association pointed out that as early as in 1800 it's already pointed out the big
timber framework has the enough fire resistance.But in nowadays ,the society has
a wrong conception that the steel and iron cannot burn.In fact, when the lumber's the cross section has certain degree,even if surface combustion,it can form the
carburization zone after,so the way of lumber's burning way can change slowly,and
intensity of the lumber interior cannot change weakly.We can konw from the result of fireproof experimental by the wooden joist and the steel system joist, the
wooden joist which don't have the protection and chemistry processing has a higher fire resistance than the non-protection steel system joist in the scene of
a fire and carries a heavy load in the size same situation,has a higher fire resistance than the steel system joist,has a higher fire resistance.Majority of
modern people live in the RC (Reinforced Concrete, reinforced concrete) structure building,but the RC structure building mostly has shortcoming that it doesn't
ventilate , has high temperature in summer,so you always can feel sultry.
And in the room it can multiply germ and some allergic sources,which causes
hygiene condition of the rooms to go bad. The lumber compares with other building materials, its water absorbability is higher and can carry on the temperature
control along with the humidity change, therefore don't need to worry the lumber
can be affected its intensity because of absorbing the excessively moisture or has other not good influence to the building. |
