Abstract
The invention discloses a kind of production methods of Reactive Powder Concrete composite beam.Composite beam is mainly made of the Reactive Powder Concrete precast beam of mixing of steel fiber, overlapping layers, vertical muscle, U-stirrups and stirrup cap.Reactive Powder Concrete composite beam need to pour in two times, and to guarantee that precast beam and the overlapping layers of Reactive Powder Concrete composite beam form whole co-operation, superposed surfaces are roughened.Reactive Powder Concrete is applied to iterative structure by the present invention, is promoted iterative structure to develop to superelevation, slim and graceful, large span, high resistance to direction of waiting so long, is complied with the demand of current social development.
Description
Technical field
The present invention relates to a kind of production methods of Reactive Powder Concrete composite beam.
Background technique
Reactive Powder Concrete is the good new material of a kind of superhigh intensity, high-durability, high tenacity, volume stability,
The construction requirements for meeting economical and environment-friendly society, promote structure to it is towering, slim and graceful, greatly develop across, high resistance to direction of waiting so long.Reinforcing bar is mixed
Solidifying soil iterative structure can save material, shorten the construction period, improve the overall stiffness and anti-seismic performance of structure, while avoid assembled mixed
It the shortcomings that Xtah Crude Clay structure and cast-in-place concrete structure, has a good application prospect, in order to promote iterative structure to superelevation, gently
Be full of, large span, high resistance to direction of waiting so long are developed, this excellent material of Reactive Powder Concrete, which is applied to iterative structure, seems outstanding
It is important.
Summary of the invention
Present invention aims at Reactive Powder Concrete is applied to iterative structure, promote iterative structure to superelevation, it is slim and graceful,
Large span, high resistance to direction of waiting so long are developed, and the demand of current social development is complied with.
The present invention is implemented as follows: Reactive Powder Concrete composite beam include bottom indulge muscle, U-stirrups, precast beam,
Muscle, stirrup cap and overlapping layers are indulged in superposed surfaces, top.
It is fine that the steel that percent by volume is 2% is mixed in the Reactive Powder Concrete for pouring precast beam and overlapping layers
Dimension.
Make the specific steps of Reactive Powder Concrete composite beam are as follows:
One, Reactive Powder Concrete composite beam pours in two times, in order to control the accuracy for pouring height every time, in two times
Make side template, the side template height of production is identical with prefabricated height for the first time, the side template height of second production with entirely
Deck-molding is identical.Beam bottom portion is indulged into muscle and U-stirrups binding is securely put into the template of production for the first time, is occurred in order to prevent swollen
Mould phenomenon, in template top surface, nail batten is reinforced.
Two, according to Reactive Powder Concrete match ratio weigh needed for a variety of materials, by the quartz sand of three kinds of different-grain diameters,
Cement, silicon ash are successively poured into forced mixer by first big after small sequence, and the suitable steel of steel fibre is sieved stirred
Mixing material is repeatedly sieved into journey, siccative elder generation premixing 4 minutes is sufficiently mixed solid material.Water-reducing agent and water are added again, stirring
5~8 minutes, stir after-pouring concrete.
Three, superposed surfaces are smoothed out after the completion of pouring for the first time, standing 20~carry out intersecting after forty minutes and draw a hair draws hair depth
For 6mm, drawing hair spacing is 100~150mm, keeps superposed surfaces uneven, stands remove side form afterwards for 24 hours at room temperature, with wet
Sawdust covering, natural moisture-keeping maintaining 28d at room temperature.
Four, second of production side template on conserving the component completed, it is secondary to pour the preceding superposed surfaces cleaning that drawn hair
Completely, brush plain-water slurry is together to guarantee that precast beam and overlapping layers bonding are good, then back portion is indulged muscle and is bound with U-stirrups
Securely, finally stirrup cap is bound and forms combined closing stirrup on opening reinforcing bar.
Five, after the completion of pouring for the second time, demoulding after standing at room temperature for 24 hours is covered with wet sawdust, at room temperature certainly
Right moisture-keeping maintaining 28d.

Specific embodiment
The present invention is described in detail below.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
Embodiment:
Reactive Powder Concrete is applied to iterative structure by the present invention, is implemented as follows:
As shown in Figs 1-4.Reactive Powder Concrete composite beam includes that muscle 1, U-stirrups 2, precast beam 3, overlapping are indulged in bottom
Muscle 5, stirrup cap 6 and overlapping layers 7 are indulged in face 4, top.
It is fine that the steel that percent by volume is 2% is mixed in the Reactive Powder Concrete for pouring precast beam 3 and overlapping layers 7
Dimension.
Make the specific steps of Reactive Powder Concrete composite beam are as follows:
One, Reactive Powder Concrete composite beam pours in two times, in order to control the accuracy for pouring height every time, in two times
Make side template, the side template height of production is identical with prefabricated height for the first time, the side template height of second production with entirely
Deck-molding is identical.Beam bottom portion is indulged muscle 1 to bind in the template for being securely put into and making for the first time with U-stirrups 2, is occurred in order to prevent
Swollen mould phenomenon, in template top surface, nail batten is reinforced.
Two, according to Reactive Powder Concrete match ratio weigh needed for a variety of materials, by the quartz sand of three kinds of different-grain diameters,
Cement, silicon ash are successively poured into forced mixer by first big after small sequence, and the suitable steel of steel fibre is sieved stirred
Mixing material is repeatedly sieved into journey, siccative elder generation premixing 4 minutes is sufficiently mixed solid material.Water-reducing agent and water are added again, stirring
