Description
Technical field
The utility model relates to a kind of building unit, especially relates to a kind of Prefabricated Reinforced Concrete Square Pile, belongs to building material field.
Background technology
China's precast concrete pile is fast-developing more than 20 year, produces from national precast concrete pile, and within 2011, preformed pile output has reached 2.8 hundred million meters; Global economy depression in 2012, China's concrete precast pile is produced and has been experienced the recent two decades underproduction first, and output is 2.6 hundred million meters; The above concrete precast pile cumulative production of the scale first half of the year in 2013 increases by 11.1% on a year-on-year basis.Above-mentioned data show that precast concrete pile occupies very important position in China's concrete and cement products industry, and the market demand is very large.
Prefabricated Reinforced Concrete Square Pile, as a kind of stake type wherein, has himself advantage.Compared with prestressed concrete pipe pile, this solid design of square pile, has increased second moment of area, contributes to improve the tensile capacity of square pile; Secondly in the design of the structure of square pile, adopt high amount of reinforcement, contribute to equally to improve the stress performance of square pile.As compared with PHC-400 (95) A-C80, in Ф 400mm, connect square and approach 300 × 300mm, circumscribed square is 400 × 400mm, in the time that Crack Control is 0.2mm, press the maximum stretching resistance of pile body that load effect standard combination is calculated, Driven Piles, cross section 300 × 300, length are no more than the C stake (C50) of 12m, pile body stretching resistance 245KN; Driven Piles, cross section 400 × 400, length are no more than the C stake (C50) of 12m, pile body stretching resistance 385KN, with approaching of PHC-400 (95) A-C80, main muscle is the reinforcing bar of 8 Ф 18, and the main muscle of PHC-400 (95) A-C80 is 7 Ф 9.0.
In atlas 04G361 " Prefabricated Reinforced Concrete Square Pile ", stirrup must adopt manual colligation to be connected with main muscle, and not only handwork amount is large, production efficiency is low, can not meet modern factories production requirement; And stirrup position dimension error is large, cause pile body mechanical property to reduce and durability deficiency, particularly, low, the resistance to poor performance that impacts of its end place vertical bearing capacity.
Summary of the invention
The technical problem solving: for overcoming the defect of prior art, provide a kind of stirrup position dimension error little, be suitable for roll welding operation, production efficiency is high, and pile body mechanical property is strong, vertical bearing capacity is high, the resistance to Prefabricated Reinforced Concrete Square Pile impacting.
Technical scheme: enhancement mode Prefabricated Reinforced Concrete Square Pile of the present utility model, comprise that cross section is square pile body main body, main muscle, stirrup, pile cover and concrete, main muscle longitudinally arranges along pile body, and described pile cover is made up of end plate and shirt rim, is provided with longitudinal anchor rib in end plate inboard; Described stirrup is the spirality stirrup that is welded on main muscle outer rim, and it is foursquare column reinforcing cage main body that main muscle and spirality stirrup connect into cross section.
First the anchor rib that, square pile of the present utility model is set up at stake petiolarea can improve the intensity of a petiolarea.Secondly, the helical structure of spirality stirrup, can realize in roll welding mode main muscle and stirrup are connected into square reinforcing cage main body, greatly enhances productivity.Meanwhile, the spirality stirrup that the utility model is made by roll welding, can ensure pitch precision and the mechanical property of stirrup, strengthens the horizontal restrain power of stake petiolarea, improves the vertical carrying of pile body.
Described spirality stirrup is less than its pitch in the pile body district at middle part in the pitch of the stake petiolarea at anchor rib place, with the mechanical property of consolidating pile petiolarea.
Described main muscle is at least 8, increases progressively with 4 multiple, is arranged on 4 seamed edges of square reinforcing cage and is distributed on 4 cylinders.
Especially, the unstability of the parallelogram square for overcoming, rhombus draws hoop, the inside restraint forces that strengthens pile body opposite, diagonal angle, further to strengthen the horizontal restrain power of a petiolarea and the vertical bearing capacity of pile body, the utility model is at least provided with a pair of cross and draws hoop between described main muscle; Described a pair of cross draws hoop, is in the square cross-section of described reinforcing cage, is connecting and is being positioned at foursquare two the cross one another hoops that draw that connect the main muscle of foursquare two pairs of diagonal positions in this cross section.---in foursquare one of this described cross section, connect square, refer to that any one four drift angle in this cross section square lay respectively at the square on the foursquare four edges in this cross section.
Preferably, described cross draw hoop be arranged between the main muscle in the centre position in four cylinders of reinforcing cage, and or be arranged between the main muscle on the seamed edge in reinforcing cage diagonal angle.Aforesaid two kinds of crosses draw hoop right, can be referred to as opposite and draw hoop and diagonal angle to draw hoop.
Described cross draws hoop longitudinally to distribute along pile body, and the stake petiolarea that distributed areas are not less than anchor rib place, to strengthen especially the horizontal restrain power of a petiolarea, improves the anti-fight performance of stake petiolarea.
For the effect that further strengthening cross draws hoop, described longitudinal adjacent two pairs of spacing that cross draws hoop, be less than the pitch of the spirality stirrup at its place place.
Beneficial effect: square pile of the present utility model compared with prior art, there are two large advantages: anti-fight power and the vertical bearing capacity of (1) stake end increase, the utility model is when stake end is set up anchor rib, the alternative square stirrup of the prior art of compound reinforcement manner and the rhombus that draw hoop to combine with spirality stirrup and cross again draw hoop, strengthen concrete horizontal restrain effect, can significantly improve anti-fight power and the vertical bearing capacity of stake end.(2) production efficiency improves, and spirality stirrup of the present utility model and main muscle can adopt roll welding mode to weld, in improving the dimensional accuracy of reinforcing cage, reduce again handwork amount, be conducive to ensure product size and quality, enhance productivity, reduce the cost of production of single pile.
