Abstract
The invention discloses a preformed pile connecting structure which comprises positioning rings (1) and connecting hoops (2). The positioning rings (1) are preformed at the periphery of the connection parts of preformed piles (4); the connecting hoops (2) are sleeved at the periphery of the two positioning rings (1) of the two preformed piles (4) needing to be connected; and the connecting hoops (2) and the positioning rings (1) are fastened by a plurality of bolts. Due to the adoption of the preformed pile connecting structure, the preformed piles can be connected firmly, and the connection parts of preformed piles can meet the force bearing requirement.
Description
Technical field
The present invention relates to the preformed pile technical field, be specifically related to a kind of preformed pile pile extension structure.
Background technology
At present; The pile extension of China's preformed pile in foundation pile construction mainly is welded construction; Welded construction is owing to be site operation, can not satisfy that the end plate end face need be cleared up, the electric welding of jointing positions groove groove needs that three layers of symmetry are carried out, weld seam needs the pile joint full, that welding is accomplished to need after the nature cooling continuously regulations such as pile sinking, thereby causes welding quality not guarantee; The preformed pile pile extension is insecure, causes the preformed pile junction to become the weakest link of foundation pile.
So; Prior art also has only a few to adopt the meshing structure of machinery to accomplish the pile extension of preformed pile; This kind pile extension structure adopts that pipe joint stake band connecting pin is connected the pot shell ways of connecting with the compression spring band of following pipe joint stake on each, is connected with the interaction of compression spring through each connecting pin.But this kind pile extension structure is owing to be that each connecting pin interacts respectively, and it all is identical being difficult to each connecting pin of assurance stressed, so after preformed pile connects, can not guarantee that in loading process pile extension partly reaches force request.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can make pile extension between the preformed pile firmly, pile extension partly reaches the preformed pile pile extension structure of force request.
For addressing the above problem; The present invention provides a kind of preformed pile pile extension structure; Comprise that prefabricated stake in preformed pile connects the peripheral locating ring in position, is socketed in the peripheral connection hoop of two locating rings that two need stakes connect preformed pile, connects between hoop and the locating ring by a plurality of bolton.
The specific operation process that this preformed pile pile extension structure connects two preformed piles is:
(1) in process of production the directly prefabricated stake at preformed pile of the locating ring that processes is connect the periphery, position;
(2) one of construction earlier the is prefabricated preformed pile of locating ring;
(3) preformed pile of an other prefabricated locating ring is aimed at placement with the preformed pile of having constructed, and make the screwed hole on the locating ring of two preformed piles be positioned at same axis;
(4) will connect the locating ring periphery that hoop is socketed in two preformed piles, and, fix with bolt then the screwed hole on its screwed hole aligned ring.
After adopting above structure, the present invention compared with prior art has the following advantages: be connected firmly between two preformed piles that connect through above structure stake; And the pile extension part is stressed evenly, test shows each item mechanical property, and flexural strength, tensile strength, shear strength all reach construction reference; The preformed pile that can be used for number of different types connects; As: PHC stake, PHDC stake, PHRC stake, SP steel pipe and STC stake, and this preformed pile pile extension structure link is convenient, and applicability is strong.
The end plate end of said preformed pile is provided with the radial protrusion ring, and the inwall of said connection hoop is provided with the groove that is used for ccontaining radial protrusion ring.Connect more firm between the preformed pile that such structure connects two need stakes.
Said connection hoop constitutes for being spliced into a circle by a plurality of arc parts, and being preferably by three radians is that 120 ° arc part is spliced into a circle and constitutes.Such connection hoop both can have been realized connecting hoop and connect the periphery, position in the stake of two preformed piles, can prevent the discontinuity that too much causes owing to arc part again.
The internal diameter of said connection hoop equals the external diameter of locating ring.This connection that two need stakes are connect between the preformed pile is more tight and firm.
Spacing equates between said a plurality of bolt.This preformed pile that two need stakes are connect is peripheral stressed more even.
Description of drawings
Shown in the drawings is the schematic cross-section of preformed pile pile extension structure of the present invention.
Wherein: 1, locating ring; 2, connect hoop; 3, bolt; 4, preformed pile; 5, end plate; 6, radial protrusion ring; 7, groove.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is made further detailed description.
Of accompanying drawing, preformed pile pile extension structure of the present invention comprises that prefabricated stake in preformed pile 4 connects the peripheral locating ring 1 in position, is socketed in the connection hoop 2 that two need stakes connect two locating rings, 1 periphery of preformed pile 4.Connect between hoop 2 and the locating ring 1 by a plurality of bolt 3 fasteningly, spacing is equal between a plurality of bolts 3.End plate 5 ends of preformed pile 4 are provided with radial protrusion ring 6, and the inwall that connects hoop 2 is provided with the groove 7 that is used for ccontaining radial protrusion ring 6.Connect hoop 2 for being that 120 ° arc part is spliced into a circle and constitutes by three radians.Certainly, connecting hoop 2 also can be for being that 90 ° arc part or other arc parts is spliced into a circle and constitutes by two semi-circular features or four radians.The internal diameter that connects hoop 2 equals the external diameter of locating ring 1.
Above embodiment is to explanation of the present invention and further explanation, rather than limitation of the present invention, and any modification of in interest field of the present invention, being done all falls into protection scope of the present invention.
