Description
Technical field
The utility model is related to a kind of composite structure, especially a kind of bamboo wood armored concrete structure belongs to building
Building field.
Background technology
In the middle of the 19th century, reinforced concrete structure is gradually used, so far only more than 100 years time, and but development is swift and violent.
At present, reinforced concrete structure has become the most common construction style of China's building trade.However, although reinforcing bar makes up well
The problem of concrete tensile strength is relatively low, enhances the intensity of concrete, but armored concrete there is also high cost-effectivenes and
The shortcomings that non-renewable.In addition reinforcing bar is easily rusted, therefore reinforced concrete structure answering on some Special zones
With being also somewhat limited.
In order to ensure economic sustainable development, energy crisis is avoided, finds a kind of free of contamination material of inexpensive low consumption
Material replaces steel rib reinforced concrete, and it is our current major tasks to change existing building form.Therefore, many researchers will grind
Directional steering is studied carefully using Material reinforcements concrete performances such as plant fibers, and wherein bamboo wood is because its unique advantage is in numerous plant fibers
In show one's talent.First, bamboo belongs to grass, and compared to slow-growing timber, its growth cycle is short, 3 to five years
Can maturation reach maximum intensity；Secondly, bamboo has very high tensile strength, is known as " plant steel bar ", some kind bamboos
The ultimate tensile strength of son is even similar with the tensile strength of mild steel, however its weight is but more light than steel；In addition, production
The energy consumption of bamboo wood also well below the energy consumption of production steel, can greatly reduce the consumption of the energy, save natural resources, reduce dirty
Dye.The bamboo resource very abundant in China, bamboo grove area account for a quarter of world's gross area, and bamboo wood is applied to enhancing coagulation
This behave of soil structure also takes full advantage of the bamboo timber resource in China.
Common bamboo wood enhancing coagulation structure is primarily present problems with and deficiency：(1) caking property of bamboo wood and concrete with
Reinforcing bar is poor compared with the caking property of concrete, and bond-slip destruction easily occurs under load action；(2) bamboo wood is brittleness material
Material, it is difficult to bend, be difficult to be molded rectangular in form when being especially used as stirrup；(3) simple bamboo wood is applied to inside concrete, bamboo
There is durability deficiency in material；(4) elasticity modulus of bamboo wood is smaller, under the same conditions than the deformation of Reinforced Concrete Units
It is larger, it is necessary to enhance with cracking.Only solve the problems, such as it is above-mentioned these, could further be promoted bamboo wood enhance concrete structure in work
The applicability of journey structure promotes its application in civil engineering.
The content of the invention
The purpose of this utility model is to provide a kind of bamboo wood armored concrete structure, overcomes existing armored concrete and common
Some shortcomings existing for bamboo wood enhancing coagulation structure play the two material advantage of bamboo wood and concrete, it is mixed to improve bamboo wood enhancing
The performance and applicability of Xtah Crude Clay structure, the vertical or horizontal member available for engineering structure field.
For this purpose, a kind of bamboo wood armored concrete structure provided by the utility model, including concrete, longitudinal bamboo reinforcement, bamboo wood
Stirrup, fibre bundle, longitudinal bamboo reinforcement are longitudinally arranged along component axis, and bamboo wood stirrup is transversely to the machine direction bamboo reinforcement arranged for interval, longitudinal bamboo
The core of muscle and bamboo wood stirrup is bamboo wood, and surface is equipped with anti-corrosion enhancement layer and sag and swell, and anti-corrosion enhancement layer is answered for fiber reinforcement
Condensation material forms and is stained with gravel, and anti-corrosion enhancement layer coats longitudinal bamboo reinforcement and bamboo wood stirrup using laying, winding or pultrude process,
Its machine direction is consistent with bamboo fiber direction, fibre bundle impregnating resin glue racking seizing longitudinal direction bamboo reinforcement and bamboo wood stirrup it is intersecting
Node forms bamboo reinforcement skeleton, and bamboo wood stirrup is cut by pre- round or rectangle bamboo trunk along cross section, and sag and swell is using recessed
The form of slot or fin, concrete are wrapped in bamboo reinforcement skeleton and form bamboo wood enhancing concrete structure.
The groove or fin is adopted on the surface of longitudinal bamboo reinforcement or bamboo wood stirrup for spiral or discontinuous, sag and swell
With groove or fin to enhance the cohesive force between longitudinal bamboo reinforcement or bamboo wood stirrup and concrete.
The fin is wound in longitudinal bamboo reinforcement using fibre bundle yarn impregnating resin glue or the surface of bamboo wood stirrup is formed,
It is arbitrary to wind spacing.
The fibre bundle is glass fibre, carbon fiber, aramid fiber or basalt fibre one or more of which.
The resin glue is epoxy resin, one kind in vinylite, polyurethane resin.
Longitudinal bamboo reinforcement and the cross sectional shape of bamboo wood stirrup are respectively one kind circular, in polygon.
In the utility model, anti-corrosion enhancement layer is formed for fibre reinforced composites, uses laying, winding or pultrusion work
The longitudinal bamboo reinforcement of skill cladding and bamboo wood stirrup, while ensure that the durability of longitudinal bamboo reinforcement and bamboo wood stirrup, improve longitudinal direction
The rigidity of the mechanical property of bamboo reinforcement and bamboo wood stirrup, especially section reduces deformation and the crack of bamboo wood enhancing concrete structure
Width；Bamboo wood stirrup is cut by pre- round or rectangle bamboo trunk along cross section, is solved bamboo wood and is difficult to complete to form stirrup
Problem；Longitudinal bamboo reinforcement and bamboo wood stirrup surface are equipped with sag and swell, ensure that the adhesive property of bamboo wood and concrete；Using fibre
The glue realization of dimension beam impregnating resin connects the binding of longitudinal bamboo reinforcement with the crossed node of bamboo wood stirrup, and bamboo wood stirrup is overcome to be difficult into
The technical issues of type rectangular in form.
The utility model overcome conventional steel bar concrete and common bamboo wood enhancing coagulation structure some defects, have with
Lower advantageous effect：
(1) enhancing of the anti-corrosion enhancement layer to longitudinal bamboo reinforcement and bamboo wood stirrup, be significantly increased the bearing capacity of component with
Rigidity, it is suppressed that the cracking of concrete reduces the deformation of structure.
(2) combination of fibre bundle and longitudinal bamboo reinforcement and bamboo wood stirrup is impregnated, realizes the spirit of bamboo wood enhancing concrete structure
Activity has preferable economy.
(3) compared with reinforced concrete structure, bamboo wood enhancing concrete structure reduces the uses of steel, and bamboo timber resource
It is abundant, there is recyclability, energy consumption is low, energy conservation and environmental protection.
(4) compared with the reinforcing bar easily corroded, the fine corrosion resistance of the bamboo wood of anti-corrosion enhancement layer is coated, to ground knot
The higher special engineering of the requirements for anticorrosion such as structure, offshore structure also has the interim knot removed in the later stages such as applicability, especially supporting
Structure.
