Nowadays, with the continuous improvement of living standards, people are more and more advocating nature, paying attention to health, and advocating the concept of energy conservation and environmental protection is also more and more recognized, followed by the wood structure building with its natural affinity into people’s life, the nine advantages of wood structure building, do you know? 1、 Wood is green, low-carbon, healthy and safe
. 
Wood gives people a comfortable feeling of natural affinity
. 
There are a lot of phendoline released from wood in wood structure buildings (which can kill bacteria in the air, curb human diseases, enhance immunity, restore consciousness, improve memory, reduce blood pressure, stabilize human autonomic nervous system and make human feel comfortable) and negative effects Ions (known in science and medicine as “air vitamins”)
. 
Radon is the most important source of pollution for household, and wood structure buildings hardly emit radon
. 
According to a study by Tsinghua University, a 100 m2 wooden building can store 29 tons of carbon without carbon emission
. 
2、 Stable and durable, moisture-proof and insect proof wood structure building is resistant to settlement and aging, fully accepts the earth’s magnetic field, and has stable balance
. 
With the application of modern science and technology, it has a service life of more than 100 years and is durable
. 
In the wood structure building, the wood itself has the function of moisture absorption and desorption, which can directly ease the change of indoor humidity, and there is a breathing paper in the middle of the multi-storey roof, so that the moisture can be discharged smoothly, and the rainwater can be avoided to invade the interior, and the internal and external balance can be maintained, so that the humidity can be effectively adjusted
.
The annual average indoor humidity is 8-10% lower than that of brick and concrete buildings, and the variation range is about 60-80%, which is closest to the index of 60% relative humidity of the best living environment
.
The components of wood structure building are processed through a series of physical processes, which are harmless to human beings and have certain moth proof effect
.
Especially, the average moisture content of wood used for construction is below 14%, which becomes another natural barrier against moth
.
3、 In the structure, wood structure building has the best seismic performance
.
It has strong resistance to instantaneous impact load and periodic failure, and can reset itself elastically without collapse during earthquake
.
According to an investigation and analysis in Canada, wood has carbonization effect
.
In case of fire, carbonization layer will be formed on the surface of wood
.
Its low conductivity can effectively prevent the flame from spreading inward
.
In case of fire, the fire will spread to the second floor after 45 minutes
.
The excellent thermal conductivity of steel structure will lead to rapid heating, softening and falling of the whole steel structure
.
Traditional houses will be covered by fire in 10 minutes It’s all around
.
When the high temperature of the building fire reaches 200 ℃, the steel structure will lose its structural integrity, and the resistance is less than 20%; while the resistance of the wood structure building is still 80% even if it burns for 50 minutes
.
4、 The construction period is short and suitable for all seasons
.
All wood structure building components and connectors are produced and prefabricated in the factory
.
The main structure of a 200 m2 house can be installed in 15 days, and other projects can be completed in 20 days and delivered for use
.
It takes six months for a brick concrete structure house to be built
.
And the seasonal change has little influence on the construction of wood structure buildings
.
5、 Environmental protection, energy saving, thermal insulation and sound insulation wood structure building takes natural green wood as raw material, which does not pollute the environment in the construction process
.
The porous structure of wood is superior to other materials in sound insulation, which is 4 times of brick concrete structure
.
The roof and floor are made of thermal insulation material, which has good thermal insulation and sound insulation performance
.
The thermal conductivity of wood is low, which is one sixth of that of brick concrete structure
.
The thermal insulation value of wood is 16 times higher than that of standard concrete and 400 times higher than that of steel
.
The research shows that the thermal insulation performance of 120 mm thick wood structure wall is equivalent to that of 720 mm thick brick wall, which can save 50-70% energy compared with brick concrete structure
.
6、 The design is flexible, the rate of house acquisition is high, the timber structure building adopts standard timber, and the plane layout is more flexible
.
Because of factory production, designers can use more imagination to design, and can make arbitrary changes to the non load bearing structure after completion, which other building systems can’t do
.
Because of its good heat insulation performance and strong support, it can release more space as long as needed
.
For the same building area, the occupancy rate (usable area) is 15-20% higher than that of brick concrete structure
.
7、 Because wood is porous material, the surface forms small concave convex, which absorbs part of the light and diffuses the light, making the light soft in vision
.
The surface of the wood does not produce static electricity, and the handle is mild
.
Because of its natural characteristics, combined with modern science and technology, the best interior and exterior decoration makes people enjoy modern life and return to nature
.
8、 Because of its characteristics of heat insulation, temperature and humidity regulation, anti-seismic and anti-corrosion, fire protection and environmental protection, it is suitable for both north and south of China
.
It has a wide range of uses
.
For example, from villas, large clubs, high-end hotels to ordinary buildings, swimming pools, saunas, bathrooms, to guard rooms, special bookstores and so on
.
It is especially suitable for the construction of ecological functional areas, tourism, leisure, health care, pension and other places, without damaging the integration of environment and nature, which is incomparable with brick concrete structure
.
9、 The total cost is low and the performance ratio is high
.
Although the one-time investment of wood structure house is higher than that of brick concrete house, the house acquisition rate of wood structure house is about 20% higher than that of traditional brick concrete house, and the house cost is about the cost paid in the whole life cycle of the house
.
Including the construction cost, use cost and operation cost of the house
.
It is estimated that the actual construction cost of wood structure houses is 25% – 53% higher than that of traditional houses
.
From the use process of the house, the operation energy consumption of the wooden structure house is 23% lower than that of the traditional concrete structure
.
In the whole life of the building (calculated according to the use of 50 years), the energy saving of the wooden structure building will greatly reduce the operation cost of the building
.
According to the comprehensive calculation, the cost gap between the wooden structure building and the traditional brick concrete building is only 3.5% – 11.4% Because of more than 30 years, the cost of wood structure house is lower than that of traditional brick concrete house
.
The wood structure house has incomparable advantages in heat preservation, energy saving, environmental protection, comfort, structural flexibility and other aspects of the traditional brick concrete structure..
