Description
Technical field
The utility model relates to a kind of reinforced concrete pile, particularly a kind of full prestressing steel concrete filled circles stake.
Background technology
In Building Engineering Design, common precast reinforced concrete piles is difficult to reach 4-5N/mm
2tensile stress.Therefore in the ordinary course of things, pile sinking buries in process, and preformed pile there will be crack unavoidably, and especially elongated stake also there will be crack in stacking, transporting and hoisting, setting process.And stake is in when underground, the erosion due to infiltration and hazardous substances, also can affect its durability.And even if the increasing reinforcement ratio still is difficult to solve the pile body crack problem, one can not guarantee the application life of stake, and two can not guarantee workmanship.Though current used pile for prestressed pipe has improved the cracking resistance of stake simultaneously, but due to pile tube thin-walled percolation-proof and corrosion resistance poor, and anti-fight not, its tensile capacity and shearing resistance are lower, therefore be prone to brittle failure at the construction pile, cracked, main muscle pier nose drops to the phenomenon that end plate lost efficacy, and affects the pile extension quality.Therefore need now a kind of Novel reinforced concrete stake that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, a kind of structure is proposed ingenious, reasonable in design, bearing capacity of single pile is high, pile body vertical bearing capacity characteristic value is large, tensile capacity is large, cracking resistance moment of flexure and ultimate bending moment can meet requirement of engineering, pile body is crack, anti-fight, anticorrosive not, and is convenient to the full prestressing steel concrete filled circles stake that continuous production-line style construction is produced.
Technical solution of the present utility model is: the stake of a kind of full prestressing steel concrete filled circles, comprise pile body 1, it is characterized in that: the cross section of pile body 1 is for circular, pile body 1 is comprised of cage of reinforcement and the concrete be filled on cage of reinforcement, cage of reinforcement comprises the main muscle 2 of outer ring, the main muscle 2 that quantity is 2n (n is natural number) is uniformly distributed on the circumference of pile body 1, main muscle 2 is integral by stirrup 3 colligations, stirrup 3 is divided into inner ring stirrup 4 and outer ring stirrup 5, outer ring stirrup 5 is wrapped in outside all main muscle 2, form the outer stirrup polygon that the limit number is 2n, inner ring stirrup 4 is wrapped in outside a plurality of main muscle 2 in the mode at interval of a main muscle 2, form the interior stirrup polygon that the limit number is n, inner ring stirrup 4 and outer ring stirrup 5 spiral winding on the length direction of pile body 1, cage of reinforcement also comprises the net sheet muscle 6 that is arranged on the pile body two ends, be provided with end plate 7 and skirtboard at the two ends of pile body 1.
Described inner ring stirrup 4 is identical with the hand of spiral of outer ring stirrup 5.
The hand of spiral of described inner ring stirrup 4 and outer ring stirrup 5 is contrary.
The utility model compared with the existing technology, has following advantage:
The disclosed reinforced concrete pile of the utility model, adopt solid cylinder pile body structure, and adopt bilayer, double-helical stirrup that main muscle colligation is structure as a whole, this special main muscle fixed form is changed into tension and compression stress by tensile stress, strengthen the stirrup cross section and improved its design strength, and its central axis moment of inertia of circular solids stake, pile body cross section increase, so shearing resistance, bending resistance, vertical bearing capacity of single pile, tension bearing capacity after its pile, cracking resistance moment of flexure, ultimate bending moment etc. all are greatly improved.Filled circles stake free from flaw in piling construction of this kind of form of structure, and there are the advantages such as anti-fight, corrosion resistance.It is the desirable structural element of contemporary pile foundation.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
The schematic diagram that Fig. 2 is the utility model embodiment cage of reinforcement end.
Fig. 3 is that the utility model embodiment stirrup is wrapped in the schematic diagram on main muscle.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.As shown in Figure 1, Figure 2, Figure 3 shows: the stake of a kind of full prestressing steel concrete filled circles, comprise pile body 1, the cross section of this pile body 1 is circular, it consists of jointly cage of reinforcement and the concrete that is filled in cage of reinforcement, be cast on cage of reinforcement; Cage of reinforcement comprises the main muscle 2 of outer ring, the main muscle 2 that quantity is 2n (n is natural number) is uniformly distributed on the circumference of pile body 1, main muscle 2 is integral by stirrup 3 colligations, and stirrup 3 is two: inner ring stirrup 4 and outer ring stirrup 5, wherein outer ring stirrup 5 is wrapped in all main muscle 2 outsides, forming a limit number is the individual regular polygon of 2n, is called outer stirrup polygon; Inner ring stirrup 4 is wrapped in a plurality of main muscle 2 outsides in the mode at interval of a main muscle 2, and forming a limit number is the individual regular polygon of n, is called interior stirrup polygon; And inner ring stirrup 4 and outer ring stirrup 5 spiral winding on the length direction of pile body 1, the hand of spiral of the two can be identical, also can be contrary; Cage of reinforcement also comprises the net sheet muscle 6 that is arranged on the pile body both ends, and the two ends of pile body 1 also are provided with end plate 7 and skirtboard.
A kind of full prestressing steel concrete filled circles stake of the utility model embodiment, when setting up cage of reinforcement, adopt bilayer, double helix stirrup by the many into a single integrated structure modes of main muscle 2 colligations, the mode of having avoided traditional stirrup and main muscle to be welded to connect causes main muscle injured, thereby affects the problem of pile body bulk strength.
Set main muscle 2 can also apply prestressing force by the hydraulic tensioning utensil, has greatly improved the shearing resistance after the pile, bending resistance, vertical bearing capacity of single pile, tension bearing capacity, the performances such as cracking resistance moment of flexure, ultimate bending moment.
The spacing that single stirrup is wound around can be regulated according to actual needs, and as the encrypted area for being wound around in the scope of distance pile body 1 each 1500mm of two ends, its spacing can be 50mm; And the pile body 1 of mid portion is non-encrypted area, its spacing can be 100mm.
If the curtailment of single pile body 1 in real work, can also connect as one structure by the pile body 1 of two basic embodiment by end plate 7, form long, a concrete pile that meet job requirement.
Also be respectively arranged with net sheet muscle 6 at the two ends of cage of reinforcement, after pile body 1 pour-shaping, because its two ends all are provided with the net sheet muscle 6 with booster action, therefore can greatly improve the anti-strike ability of pile body 1 end, prevent that the end of concrete pile from being occurred in impacting process that the even broken situation of crackle occurs.
