Description
Technical field
The utility model belongs to technical field of buildings, protects more particularly to a kind of thin-walled C-shaped steel cork wood composite structure load-bearing
Warm wallboard.
Background technique
According to statistics, construction industry consumes about 50% energy on the earth, 42% water resource, 50% material and 48%
Arable land.Cause disruption of ecological balance, produce global 24% air pollution, 50% greenhouse effects, 40% pollution of waterhead and
50% chlorofluorocarbons etc..
Green building curbs environmental pollution in China, energy-saving and emission-reduction, plays vital work in terms of the adjustment industrial structure
With.Past China in terms of Development of Green Building, emphasis steel construction and concrete structure and have ignored timber structure green building.
Steel, cement, plastics non-renewable unsustainable property clearly.Present developed country have been recognized that Wood construction and
The building materials processed using agricultural wastes, are the correct directions of building industry sustainable development, however department, the Chinese government and society
Can all circles for the extensive use of novel Wood construction, there is also many mistaken ideas.
For this reason, it is necessary to carry out systematic research and development for timber structure green building and its industrialization, produce China's building
Industry really realizes the green, recyclable, sustainable of overall process.
Ancient and modern timber buildings start the arena theatre for gradually returning to construction industry, and mainly timber structure is built
It builds with advantages such as huge sustainable developments: 1. green: forest one cubic metre of timber of every growth, the titanium dioxide caning absorb in atmosphere
About 850 kilograms of carbon.And produce one cubic metre of steel and discharge 12 tons of carbon dioxide, a cubic meter of concrete discharges 3 tons of carbon dioxide.
In addition, containing a large amount of polyphenol powde and the referred to as vitaminic anion of air in timber buildings room air, beneficial to the people
It is physically and mentally healthy.2. energy conservation: the properties of heat preservation and energy saving of wooden frame structure is better than other any other structure types.The insulation value of timber
It is 16 times higher than concrete, it is 400 times higher than steel, it is 1600 times higher than aluminium.3. environmental protection: timber be naturally can growth material, steel
It is 120 times big to the damage ratio timber of water.4. anti-seismic performance: timber structure has superior flexibility, good ductility and energy consumption energy
Power.Even if strong earthquake makes whole building be detached from its basis, structure is also often intact.Timber structure toughness is big, for
Moment impact load and Cyclic fatigue destruction have very strong resistivity, have optimal shock resistance in all structures, this
A little sufficiently proved in many big earthquake centres.5. durability: timber is a kind of stabilization, the material that the service life is long, durability is strong.
The numerous ancient times Wood constructions in China experienced the hardships precipitation of more than one thousand years, still stand erect.External a large amount of wooden houses, have used
Centuries still plays and preferably to use function.6. fire resistance: the timber structure of flame retardant treatment has charing effect, low
Conductibility effectively can prevent flame from inwardly spreading, to guarantee that entire timber structure is not damaged within some time.7. design spirit
Living, utilization rate height: compared with steel construction, concrete structure and masonry structure, the type of attachment of timber structure is the most various, space cloth
The most flexible, the utilization rate highest of office.8. construction: the construction period of timber structure is most short, and weatherproof, all may be used any time
With construction.
Timber buildings not only have huge sustainable development advantage, and have enormous industrial advantage: 1. assembling rate
High: concrete structure is difficult more than 80%, and timber structure can reach 100%.2. standardization, general rate are high: Structural Laminated Wood material list
One, standardization, generalization degree are higher than concrete structure.3. job-shop automation is horizontal high: timber structure machinability is strong, workshop structure
The percent of automatization of part production is much higher than concrete structure.4. processing cost is low: wood structures are not necessarily to mold, pour and conserve,
It processes time saving, saving of labor, save money.5. machining accuracy is high: timber structure process is all made of lathe program control operation, and machining accuracy is high.
6. transportation cost is low: timber structure not only light weight, and shape is more regular, without a large amount of exposed steel bar.7. assembling speed is fast: assembly
There is still a need for a large amount of wet constructions for concrete structure, in contrast, the timber structure construction period can be shortened several times.8. worker requires low:
Concrete structure assembly needs large quantities of high-quality professional contingents, a large amount of precisely operations, be in the milk with it is cast-in-place.Especially a large amount of reinforcing bar
Connection, operation difficulty are big.And the installation operation of timber structure is significant simplified.9. big component general assembly: due to timber structure light weight,
It is more regular, therefore big component general assembly can be used, industrialization degree is higher.
The combination collaboration of steel wood component easily forms rationally efficient new structural form；And the steel construction auxiliary of part, can have
The innovation of the freedom degree that the relieving timber structure form of effect itself is pioneered and invented, steel wood composite construction form modern first shows spirit
It is living to use modern structure theoretical result, and the combination based on different carrying systems, the mixing of comprehensive various structural advantages and
In space structure.Further, since using novel node, many traditional integrality performance of the structure are significantly improved, are working as
It is also continued to introduce new in architectural creation, these structure types not only can solve the span that numerous traditional timber structures face and ask
Topic, but also bring the modern wood structure form of expression abundant.
The rigidity of lightweight steel construction is small, is easy to appear flat out-of-plane buckling, and be easy overall collapse.And due to keeping the temperature problem, very
Hardly possible forms modularization processing and fabricating.
The thin-walled C-shaped steel cork wood composite structure load bearing heat preserving wallboard production of the utility model is simple, at low cost, intensity height,
Simple installation.
