The present invention relates to the noggin piece and the manufacture method thereof of steel bar concrete.Be specifically related to the improvement of filling thin-walled pipe (box) and manufacture method thereof.
Concrete hollow board, particularly cast-in-situ reinforced concrete hollow slab non-core-drawing pore-creating technology mostly adopt light-wall pipe to fill, and have the advantage of convenient construction and transport.But because its tube wall mostly is a homogenous material (as paper tube), have insufficient strength, non-deformability is poor, the shortcoming that the anti-vibration damage capability is also bad.
The objective of the invention is to overcome the shortcoming of prior art, a kind of high strength, resistance to deformation, light-wall pipe (box) that the anti-vibration performance is good are provided, and easy construction, manufacture method that cost is low.
Fiber reinforcement-type light-wall conduit for reinforcing steel bar concrete filling of the present invention (box), pipe (box) wall that is characterized in described pipe (box) body is the composite in proportion high-strength compound of inorganic binder, filler, Admixture, fiber.
In order to guarantee to implement, concrete does not enter in the box and influence hollow rate, and pipe (box) body of light-wall pipe of the present invention (box) can have and seals formation cavity light-wall pipe (box); The cross section of light-wall pipe can be circular square or trapezoidal or other are special-shaped, and the cross section of thin-walled box can be circular square or spherical or polygon or other abnormity; In the thin-walled box ribs can be set, described ribs can be in-line or cross or groined type structure.
The manufacture method of fiber reinforcement-type light-wall conduit for reinforcing steel bar concrete filling of the present invention (box) is:
(1) specification, size mfg. moulding die as required, its shape can be tube core mould or box former or formpiston;
(2) the high-strength compound slip of preparation, by cement inorganic material: filler: Admixture: the weight ratio of fiber is 100: 20-350: 0.01-10: 0.1-15 gets the each component material ready, and other is mixed into high-strength compound slip at suitable quantity of water.
(3) it is floating high-strength compound slip to be coated on the mould compacting, and its mode can adopt manual or mechanical, adopts machinery high-strength compound slip to be ejected on the mould by mortar pump or cutting spraying machine, and this mode fiber should prescind, and it is floating to spray the back compacting.
(4) maintenance, the demoulding and obtain described enhancement mode light-wall pipe (box).
In addition, according to aforementioned gained, opening thin pipe (box) opening size, shape cut to seal plate and be adhered to opening part and form cavity light-wall pipe (box), and described sealing can be homogenous material or high-strength compound; On mould, can be provided with barrier film or scribble demoulding spacing agent; Admixture can be one or more in early strength admixture, water reducing agent, retarding agent, the glue; Cement inorganic material can be portland cement or portland cement or sulphate aluminium cement or iron aluminic acid cement or magnesia oxychloride cement or alkali slag cement or ground caustic coal ash cement or rapid setting cement or special cement; Fiber can be one or more in glass fiber, carbon fiber, organic fiber, the natural fiber.
