Description

Reinforced power consumption wood joist
Technical field
The invention belongs to technical field of buildings, particularly relate to a kind of reinforced power consumption wood joist.
Background technology
According to statistics, builing industry consume on the earth about 50% the energy, the water resource of 42%, the material of 50% and 48% arable land.Cause disruption of ecological balance, create the whole world 24% air pollution, the greenhouse effect of 50%, the pollution of waterhead of 40% and 50% CFC etc.
Green building is curbed environmental pollution in China, energy-saving and emission-reduction, play vital effect in industry restructuring.Past, China was in Development of Green Building, an emphasis steel work and concrete structure and have ignored wooden construction green building.The non-renewable unsustainable property of steel, cement, plastics clearly.The building materials that present developed country has generally acknowledged Wood construction and utilized agricultural wastes to process are correct directions of building industry sustainable development, but the extensive use that department of the Chinese government and various circles of society build for Novel wooden also also exist a lot of mistaken ideas.
For this reason, be necessary to carry out systematic research and development for wooden construction green building and industrialization thereof, make China's building industry really realize the green, capable of circulation, sustainable of overall process.
Ancient and modern timber buildings, start the arena stage getting back to builing industry gradually, mainly timber buildings has the advantages such as huge sustainable development: 1. green: forest often grows one cubic metre of timber, the carbon dioxide in Absorbable rod air about 850 kilograms.And produce one cubic metre of steel discharge carbon dioxide 12 tons, a cubic meter of concrete discharge carbon dioxide 3 tons.In addition, contain a large amount of polyphenol powdes in timber buildings room air and be called as the vitaminic anion of air, the useful people are physically and mentally healthy.2. energy-conservation: the properties of heat preservation and energy saving of wooden frame structure is better than any other form of structure.The insulation value of timber is higher than concrete 16 times, higher than steel 400 times, higher than aluminium 1600 times.3. environmental protection: timber be natural can growth material, large 120 times of the damage ratio timber of steel to water.4. anti-seismic performance: wooden construction has superior pliability, good ductility and energy dissipation capacity.Even if strong earthquake makes whole building depart from its basis, its structure is also often intact.Wooden construction toughness is large, and destroying for moment impact load and Cyclic fatigue has very strong resistivity, and in all structures, have best shock resistance, this point obtains sufficient proof in many large earthquake centres.5. durability: timber is a kind of stable, the life-span is long, durability is strong material.China's Wood construction in numerous ancient times experienced by the hardships precipitation of more than one thousand years, still stands erect.External a large amount of wooden house, employs the centuries, still plays using function preferably.6. fire resistance: the wooden construction through flame treatment has charing effect, its low conductivity can effectively stop flame inwardly to spread, thus ensures that whole wooden construction is not damaged in for a long time.7. flexible design, utilization rate are high: compare with masonry structure with steel work, concrete structure, the type of attachment of wooden construction is the most various, and space layout is the most flexible, and utilization rate is the highest.8. construct: the construction period of wooden construction is the shortest, and weatherproof, can construct any time.
Timber buildings not only has huge sustainable development advantage, and has enormous industrial advantage: 1. assembling rate is high: concrete structure is difficult to more than 80%, and wooden construction can reach 100%.2. standardization, general rate are high: Structural Laminated Wood material list one, and standardization, generalization degree are higher than concrete structure.3. job-shop automation level is high: wooden construction workability is strong, and the percent of automatization that workshop component is produced is far above concrete structure.4. processing cost is low: wood structures without the need to mould, pouring & maintenance, processing save time, saving of labor, save money.5. machining accuracy is high: wooden construction process all adopts lathe program control operation, and machining accuracy is high.6. cost of transportation is low: wooden construction not only quality is light, and profile is more regular, without a large amount of exposed steel bars.7. assembling speed is fast: assembling concrete structure still needs a large amount of wet trades, and by comparison, the wooden construction construction period can shorten several times.8. workman requires low: concrete structure assembling needs large quantities of high-quality professional contingent, a large amount of precisely operation, grouting and cast-in-place.Especially a large amount of bar connecting, operation easier is large.And the fitting operation of wooden construction significantly simplifies.9. large component general assembly: because wooden construction quality is light, more regular, therefore can adopt large component general assembly, industrialization degree is higher.
China is in the period of history of industrialization, urbanization and new countryside construction fast development, deeply advances building energy conservation, accelerates development green building and be faced with rare historic opportunities.Realize the great demand that the industrialization of modern wood structure green building has become national sustainable development.
Summary of the invention
In order to improve overall performance and the lateral rigidity of I-shaped wood joist, propose the method for designing of reinforced Wasted-energy steel plate (3), in order to improve its property indices further, a series of reinforcement process is carried out to it, develops that a kind of good integrity, power transmission are clear and definite, simple structure, safe and reliable, the reinforced power consumption wood joist of saving material and easy construction.
The technical solution used in the present invention is as follows:
Reinforced power consumption wood joist comprises the wooden edge of a wing, web and reinforced Wasted-energy steel plate, the wood edge of a wing is provided with groove, web lower edges inserts the wooden edge of a wing respectively, the i shaped cross section both sides that the wood edge of a wing and web are formed evenly arrange reinforced Wasted-energy steel plate respectively, and reinforced Wasted-energy steel plate connects the edge of a wing up and down respectively.
Described web lower edges inserts the wooden edge of a wing respectively and adopts structure glue to be connected with it.
Described reinforced Wasted-energy steel plate comprises delthyrium, crowsfeet, power consumption arc plate, web stiffener and edge of a wing stiffener, and edge of a wing stiffener is two pieces of horizontal steel plate, and web stiffener is one block of vertical steel plate, is therebetween power consumption arc plate; For cutting and overturning the crowsfeet of 90 ° on web stiffener and edge of a wing stiffener, crowsfeet is vertical with web stiffener, edge of a wing stiffener respectively; Crowsfeet on web stiffener is horizontal, longitudinal is all no less than 4 rows, and the crowsfeet on the stiffener of the edge of a wing is horizontal, longitudinal is all no less than 2 rows; Delthyrium web stiffener cutting crowsfeet is symmetrical up and down along center line, and delthyrium is isosceles triangle, and down, the following delthyrium base of center line upward on center line above delthyrium base.
Described reinforced Wasted-energy steel plate adopts crowsfeet to be connected with the edge of a wing up and down respectively, and reinforced Wasted-energy steel plate and web adopt crowsfeet to be connected.
Beneficial effect of the present invention:
Effect of the present invention and advantage are that bearing capacity is high, easy construction, good economical benefit, significantly reduce that cost, good integrity, power transmission are clear and definite, simple structure, safe and reliable, save material, easy construction, matter are equal and lightweight, large load can be supported and not bending subsidence in very large span, and can reduce owing to shrinking, warping, bending, problem that distortion and cracking cause, avoid the floor that causes therefrom uneven.
