Description
Technical field
The present invention relates to a kind of building structure, and in particular to a kind of parallel truss flooring of Crossing brace.
Background technique
Light-duty wooden increasingly has been favored by people in recent years, this is determined by the good performance of light-duty wooden
's.Light-duty wooden generally has the advantage that
1) structure safety: light-duty wooden, which destroys moment impact and Cyclic fatigue, has good resistivity,
Such as in San Francisco, Kobe, TaiWan, China violent earthquake, most wood-frame houses still keep completely being exactly good card
It is bright.In addition, the timber by flame retardant treatment also has flame retarded energy, so that timber will not burn in a short time, won for fire-fighting
Obtain the time.
2) energy-saving heat preserving: timber is compared with steel, aluminium, plastics, and not only its production consumption is minimum, but also light-duty wooden is built
Also there is good heat preservation and insulation.Research shows that: identical heat insulation effect, the thickness that timber needs is the 1/ of concrete
15, when the 1/400. of steel uses same glass fibre or foamed plastics as thermal insulation material, guarantor of the timber structure than steel construction
The high 15%-70% of warm nature energy, can be such that the Energy in use of building substantially reduces.
3) environment is friendly: General Life average out to 50 years or so of building, the processing to the building material being removed,
Always perplex the big problem of urban ecological environment.For this purpose, modern material should towards " 4R " principle (Re-new, Recycle,
Reuse, Reduce) direction develop, wood materials substantially conform to above-mentioned requirements.There is scholar to do construction material life cycle pair
The comparison that environment influences, the environment-friendly advantage that discovery timber has.The production of nation-building ecological residence was both met using wooden building materials
Industry policy complies with the theory of healthy residence again.
4) protect soil: so far, China makes room every year need to produce 700,000,000,000 pieces of clay brick, 100,000 mu of damage arable land with
On.Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD), Ministry of Land and Resources etc. have sent the documents, it is desirable that forbid using solid clay brick in residential housing in limited time.Wood knot
Structure is one of good substitute of brick mix structure.
5) construction time is short, easy to maintenance: the construction period of general timber buildings is the 1/2-1/ of similar brick mix structure
3, have the characteristics that layout with moulding flexibly and repair and overhaul it is convenient.Timber required equipment when repairing or being transformed
Relatively easy, required construction personnel is also less.
6) material resources are renewable and utilize: timber is renewable resource, if forest to be subject to the management of science, adheres to giving birth to
Long amount is greater than cutting, and the forest reserves are recycled with regard to sustainable use.
7) construction cost is low: for the quality in house itself, building operability, source benefit and speed of application, wood knot
The cost-effectiveness in structure house is best.
For the flooring of light-duty wooden mainly using being made of the joist that SPF dimension stock forms, amount of deflection is a weight of joist
Want design objective, common joist often because the problem of degree of disturbing, influences user's acceptance, so that the popularization of light-duty wooden flooring
It meets obstructions.
