The triangular prism-shaped anti-corrosion reinforcing pile has the advantages that after the triangular prism-shaped pile with the reinforcements is used, concrete materials are saved; the bulged parts ensure the thickness of a reinforcement protective layer, the bearing performance, anti-bending performance and anti-corrosion performance of the pile are improved effectively, the ductility of a pile body is improved by over 20 percent, the phenomenon of the cracking of the pile body is avoided, and the integral performance of the pipe pile is improved by over 30 percent; and the triangular prism-shaped anti-corrosion reinforcing pile is simple in process, low in cost, high in cost performance and high in adaptability on geological conditions, and can be widely applied to the foundation construction of various soil textures.
Description
Technical field
The utility model relates to foundation construction technology in the civil works, particularly a kind of triangular prism shaped anticorrosion reinforcement stake.
Background technology
Piling as the foundation pile engineering is more on market, and if any pile tube, all kinds of side stake, castinplace pile, drilled pile etc., these pilings mainly divide non-prestressed member and prestressed member two big classes.The prestressed member piling comprises, pile tube, centrifugal prestress square pile etc.Their shortcoming is; The ability of four limit bearing loads is identical, and under actual a lot of operating mode, the bearing load of stake is directive; As in foundation ditch or highrise building; Little then more than needed more in main stress direction drag in another direction, cause bigger waste, there is architectural characteristic and born the unmatched phenomenon of directionality load.This problem is particularly outstanding with the areas that Taiwan, Japan, China etc. shake more in base pit engineering.Non-prestressed member stake comprises, traditional side's stake, tube-sinking cast-in-situ pile etc.It is relatively low to show as bearing capacity of single pile, and bending resistance (drawing) shear behavior is poor, long construction period, and pile quality does not meet designing requirement; Piling well damage in transportation and the use causes the pile concrete durability bad.The preformed pile smooth in appearance, the frictional force of piling and soil layer is little.Also there be a kind of end that the prestressed centrifugally concrete square pile of end plate is arranged, from heavy and light, material-saving, lifting, convenient transportation, bearing capacity of pile is big.But its main muscle layout is reasonable inadequately, and poor as main muscle, pile body anti-bending strength with prestressed reinforcement or plain bars.End plate four limits do not have the welding groove, have influenced the pile connectivity robustness.The pile body cross section is a quadrangle, and pile body very easily damages for four jiaos in the building operations, causes whole stake to be scrapped, and not only causes waste, but also can influence construction speed.
In addition; The endurance issues of construction of structures is more and more paid attention to by owner and engineering construction person in the highly corrosive stratum; The actual useful year of many traffic, electric power and industrial infrastructure project is all far below the design service life, and corrosivity stratum and underground water have caused the object of construction production later maintenance costly to the burn into corrosion function of constructional materials.
Summary of the invention
To structural deficiency in the prior art; The purpose of the utility model provides a kind of triangular prism shaped anticorrosion reinforcement stake, has been beneficial to improve effectively carrying, bending resistance and the antiseptic power of stake, has avoided pile body in work progress; Tilt, displacement is excessive, even the phenomenon of fracture.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts provides a kind of triangular prism shaped anticorrosion reinforcement stake; This includes the end plate at concrete body and two ends; Wherein: in said concrete body, be provided with the cage of reinforcement cage, described cage of reinforcement cage includes many prestressing force master muscle, nonprestressed reinforcement and spiral bars, and said prestressing force master muscle and nonprestressed reinforcement are for arrange symmetrically and evenly; Said concrete body is the triangular prism shape that the center is provided with through hole, on said triangular prism shaped each facade, is provided with the bossing of perforation, and central through hole partly forms the tensile region.
The beneficial effect of the utility model is to use the unique shape of the triangular prism shaped stake of this arrangement of reinforcement to save concrete material, and bossing has guaranteed the thickness of stake reinforcement cover, has improved carrying, bending resistance and the antiseptic property of stake effectively; The ductility that has improved pile body has been avoided the phenomenon of pile body cracking more than 20%, and the overall performance that improves pile tube is more than 30%; And technology is simple; Cost is low, and cost performance is high, is widely used in the foundation construction of various soil properties.This triangular prism shaped anticorrosion reinforcement stake is strong to geological conditions compliance, and concrete strength of pile is high, and closely knit anti-beating has stronger penetration capacity, with the geology that is corrosive stronger compliance is arranged to the bearing stratum fluctuations is big.

Fig. 3 is the triangular prism shaped pilework schematic cross-section that does not add bossing.
Among the figure:
1, prestressing force master muscle 2, nonprestressed reinforcement 3, spiral bar 4, concrete body 5, fixing end plate 6, cage of reinforcement cage 7, tensile region 8, the bossing in two ends
The specific embodiment
In conjunction with accompanying drawing the triangular prism shaped anticorrosion reinforcement pilework of the utility model is explained.
The triangular prism shaped anticorrosion reinforcement stake of the utility model; This includes the end plate 5 at concrete body 4 and two ends; In said concrete body 4, be provided with cage of reinforcement cage 6; Described cage of reinforcement cage 6 includes many prestressing force master muscle 1, nonprestressed reinforcement 2 and spiral bars 3, and said prestressing force master muscle 1 and nonprestressed reinforcement 2 are for arrange symmetrically and evenly; Said concrete body 4 is provided with the triangular prism shape of through hole for the center, on said triangular prism shaped each facade, is provided with the bossing 8 of perforation, and central through hole partly forms tensile region 7.
Described nonprestressed reinforcement 2 is evenly distributed on the spiral bar 3 in the tensile region 7.Described prestressing force master muscle 1 is the PC rod iron of tensile strength >=1570Mpa.
Function like Fig. 1, the utility model shown in 2 is achieved in that
Earlier with prestressed reinforcement 1, nonprestressed reinforcement 2, spiral bar 3 fixed length, cut off blanking, again with prestressed reinforcement 1 heading, and then the mother metal cold-drawn of spiral bar 3 become hand-drawn wire.
Make end plate 5; Then cage of reinforcement cage 6 is put into mould with end plate 5; Install concrete body 4 feedings in the mould of cage of reinforcement cage 6 and end plate 5, carry out prestressed stretch-draw behind the cover mold that closes, nonprestressed reinforcement 2 is not participated in prestressed stretch-draw.
And then mould placed carry out centrifugal forming on the centrifuge, topple over surplus slurry after finishing.
Then the mould that centrifugal forming is good is put into steam-cured pond, carries out stream curing by the strength grade of concrete requirement; And then put and open, judge the pile tube credit rating through the Quality Inspector after the demoulding, stake entrucking is again gone into still and is carried out steam curing at high pressure, puts into a yard then, carries out natural curing.
Fig. 1 and Fig. 3 contrast: Fig. 1 has increased bossing 8 than Fig. 3; And bossing 8 has increased the protective layer thickness of reinforcing bar; The effect of topping mainly is the protection reinforcing bar prevents the corrosion of reinforcing bar; Necessary simultaneously thickness also can guarantee the bond stress of concrete to reinforcing bar, to guarantee to reach the requirement of design load.
