Description
Technical field
The invention belongs to technical field of buildings, more particularly to a kind of NCCLT sound insulating floor slabs.
Background technology
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 the whole world 24% air pollution, 50% greenhouse effects, 40% pollution of waterhead and
50% chlorofluorocarbons etc..With modern wood structure science and technology and timber treatment technology continue to develop, be fully solved fire prevention, it is moisture-proof,
The series of problems such as anti-corrosion, ant proof, sound insulation allow challenge of the timber in any building, and in projected life and use
On service life, wooden frame structure is considerably longer than concrete structure house.Timber structure and its industrialized continuous development build China
Industry really realizes the green, recyclable, sustainable of overall process.Therefore, ancient and modern timber buildings start gradual
The arena theatre of construction industry is returned to, mainly timber buildings have the advantages such as huge sustainable development：1. green：Forest often gives birth to
Long one cubic metre of timber, can absorb about 850 kilograms of carbon dioxide.And produce 1 cubic metre of about 12 tons of carbon dioxide of steel discharge, 1
Cubic meter of concrete discharges about 3 tons of carbon dioxide.2. health：In timber buildings room air containing a large amount of polyphenol powde and by
The referred to as vitaminic anion of air, it is physically and mentally healthy beneficial to the people.It is 3. energy saving：The properties of heat preservation and energy saving of wooden frame structure is better than appointing
What his structure type.The insulation value of timber is 16 times higher than concrete, 400 times higher than steel, 1600 times higher than aluminium.4. ring
It protects：Timber be naturally can growth material, steel, manufacture of cement cause air, water pollution.5. anti-seismic performance：Timber structure has
Superior flexibility, good ductility and energy dissipation capacity.Even if strong earthquake makes whole building be detached from its basis, structure
It is often intact.Timber structure toughness is big, has very strong resistivity for moment impact load and Cyclic fatigue destruction,
There is best shock resistance, this point has fully been proved in many big earthquake centres in all structures.6. durability：Timber is one
The strong material of kind stabilization, long lifespan, durability.The numerous ancient times Wood constructions in China experienced the hardships precipitation of thousand, still stand erect.
External a large amount of wooden houses, are used for centuries, still play and preferably use function.7. fire resistance：Through fire-retardant
The timber structure of processing has charing effect, and low conductivity effectively can prevent flame from inwardly spreading, so as to ensure entire timber structure
It is not damaged within some time.8. flexible design, utilization rate are high：Compared with steel construction, concrete structure and masonry structure, wood
The type of attachment of structure is the most various, and space layout is the most flexible, utilization rate highest.9. it constructs：The construction period of timber structure is most
It is short, and weatherproof, it can construct any time.
Timber buildings not only have huge sustainable development advantage, and with enormous industrial advantage：1. assemble rate
It is 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 far above concrete structure.4. processing cost is low：Wood structures without mold, pour and conserve,
It processes time saving, saving of labor, save money.5. high precision machining：Timber structure process is using lathe program control operation, high precision machining.
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：Assembling
Concrete structure is there is still a need for a large amount of wet construction, in contrast, the timber structure construction period can shorten several times.8. worker requires low：
Concrete structure assembling 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 significantly simplifies.9. big component general assembly：Due to timber structure light weight,
It is more regular, therefore big component general assembly, industrialization degree higher may be used.
Cross-bedding building blocks（CLT）It is a kind of Novel wooden construction material, it is sorted and cut into using kiln drying specification finger joint lumber
Flitch, through orthogonal（90 degree）After stacking, solid wood board is composed using high-strength material, area and thickness can be customized as required；
Its main feature is that the staggered specification wood gluing of band and vertical line is molded, the alternative concrete material of intensity, surveyed through related
It takes temperature bright：With the combination of materials into Wood construction object anti-seismic performance it is good.
CLT substantially just has very strong load-bearing capacity, and whether in longitudinal direction or transverse combination application aspect,
It can serve as a kind of important load-bearing material.Theoretically, CLT can be used for the structural wood of up to 10 layers timber buildings
Material, and can be as the alternative materials of cement or steel.
CLT belongs to heavy timber construction, the crosswise lamination wood plank of large area, can directly after notch, as the exterior wall of building, floor and
Roof boarding etc. is suitable for more than ground building；Because the technology has the advantage constructed efficiently, at a high speed, and low to weather requirement,
Construction speed can be greatlyd improve.The intrinsic fabulous fire resistances of CLT, this is similar to the characteristic of heavy timber construction：Once fire occurs
Calamity, CLT wood materials surface layer can be slowly carbonized with certain rate and at the same time original inside the maintenance of energy long period
Structural strength.Therefore this charred effect can also be further ensured that the structural strength of plank.In the area that earthquake takes place frequently, in safety
The emphasis considered in design process is the shock resistance of structural system.CLT under construction makes as a kind of construction material with other
The connector and fastener used ensure that overall structure has stronger shock resistance together.Materials are natural, environmentally protective,
In whole life cycle, greenhouse gas emission can be greatly decreased；It is low to execution conditions requirement, it builds installation quickly, saves the duration,
So as to reduce cost；Compared to traditional construction material, material is light, not high to fundamental importance, is conducive to accelerate construction progress and reduce cost；
The timber buildings fire prevention of crosswise lamination timber, anti-seismic performance are excellent.
However there is also the shortcomings that itself by CLT：1. the stationary phase of the structure glue used often only has 50 years, part-structure
Glue stationary phase was less than 20 years, and timber buildings structural life-time is often up to centuries or even thousands of years, the stability of structure glue
Seriously affect the durability of structure.2. it is not only harmful to health largely using structure glue, certain destroy also is generated to environment.3. wood
Its surface is needed to be put down as mirror during material gluing, lumber recovery significantly reduces.4. the materials such as heat preservation, sound insulation can not integrate, increase
Field procedure extends the duration, increases cost.
Invention content
In order to improve the durability of CLT, glue connection is replaced using nail nail connection, no longer using chemical products, extends CL's
Service life, and avoid environmental pollution.Plank lumber recovery is greatly improved, and uses a large amount of internal cavities design side
