Description
Technical field
Light steel tube-constraint timber with small diameter combination load-bearing pillar and the practice can be assembled the present invention relates to one kind, belongs to structure work
Journey technical field.
Background technology
With the fast development of China's dwelling construction, to meet the housing need that the people is growing, house is promoted
Industry modernization, develops steel house, expands the occupation rate of market of steel house.Mode of construction innovation is promoted, is sent out energetically
Assembly concrete building and steel building are opened up, development Modern Wood Construction is advocated in the place satisfied the requirements, constantly carries
Ratio of the high assembled architecture in new building.It is contemplated that fabricated construction is by as the following main building shape of China
Formula.
With the continuous scarcity of resource, the problem of timber resources of China is also faced with sternness, because majority state should be through
Embargo virgin wood, therefore become impossible by imported timber, meanwhile, in use due to major diameter
The favor of timber, causes the timber of minor diameter (size is 40mm~130mm) seldom by complete exploitation and uses, most paths
Timber is by serious waste.How complete development and utilization is had become the research of current hotspot by the timber with small diameter that people ignores
Problem, the solution of this problem not only will effectively alleviate crisis of resource, and forest reserves supply and demand is also solved to a certain extent
Contradiction.
Carbon fiber turns into the emphasis that world today's material subject is studied with its excellent combination property.Research shows：Carbon is fine
The tensile strength of dimension>3500MPa, tensile modulus>230GPa, density is only 1.76~1.94g/cm, with excellent mechanical property
Energy and overall characteristic；Carbon fiber is used widely in building, the energy etc. field and industry.
Traditional reinforced column structural bearing capacity is generally poor, and substantial amounts of (wood) mould is needed to use in work progress
Plate, easily causes the serious waste of resource, while construction and maintenance needs the substantial amounts of duration, it is impossible to adapt to current assembled architecture
Development.Based on this, the present invention, which proposes one kind, can assemble light steel tube-constraint timber with small diameter combination load-bearing pillar, light section pipe portion
Part as outside can assembly template, the filling timber with small diameter that is constrained by FRP carbon cloths in inside holds compared to traditional concrete
Weight post, its bearing capacity is significantly improved, the characteristics of being constructed with assembling, while giving full play to and make use of timber with small diameter, is accorded with
Close the new demand of current assembled development, it is adaptable to low, multilayer assembled architecture development.
The content of the invention
There is assembling construction, simple structure, easy construction, environmental protection one it is an object of the invention to provide one kind
Light steel tube-constraint the timber with small diameter that assembles of the advantages of body combines load-bearing pillar, is held to effectively solve conventional concrete post
Loading capability is not good, and assembling efficiency is low, the low problem of resource utilization.
To achieve the above object, the present invention is adopted the following technical scheme that：
One kind can assemble light steel tube-constraint timber with small diameter combination load-bearing pillar, the combination load-bearing pillar include timber with small diameter 1,
