Abstract
The invention discloses a pile splicing structure for precast piles, which comprises inner hoops (1) and outer hoops (2), wherein the inner hoops (1) are sheathed at the peripheries of two pile splicing parts required to perform pile splicing on the precast piles; the outer hoops (2) are sheathed and fastened onto the peripheries of the inner hoops (1); each inner hoop (1) is formed in a way that two or more than two arc-shaped components are spliced to form a ring; the inner ring of the inner hoop (1) is provided with at least two radial bulge loops (4); and the periphery of each pile splicing part required to perform the pile splicing on the precast piles is provided with a groove (5) matched with the radial bulge loops (4). By adopting the pile splicing structure for the precast piles, the pile splicing among the precast piles is firm, and the pile splicing parts reach the stress 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 cause 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 provides the preformed pile pile extension structure that pile extension is firm between a kind of preformed pile, pile extension partly reaches force request.
For addressing the above problem; The present invention provides a kind of preformed pile pile extension structure; Comprise be socketed in stake that two need stakes connect preformed pile connect position peripheral interior hoop, socket and be fastened in the peripheral outer hoop of hoop; In hoop constitute for being spliced into a circle by two and two above arc parts; The inner ring of interior hoop is provided with at least two radial protrusion rings, and each stake that needs stake to connect preformed pile connects the position outer periphery and is equipped with the groove that mates with the radial protrusion ring.
The specific operation process that this preformed pile pile extension structure connects two preformed piles is:
(1) elder generation will bind round outward with locator and be fixed on the preformed pile periphery of having constructed, and hoop placement location in reserving;
(2) place the preformed pile orientation tool at the preformed pile end plate position of having constructed;
(3) an other preformed pile is aimed at placement through orientation tool with the preformed pile of having constructed;
(4) stake that interior hoop is socketed in two preformed piles connects the periphery, position;
(5) hoop was peripheral in hoop will bind round outward after putting well and be pushed in, and will bind round outward with jack and to shift the precalculated position onto.
After adopting above structure; The present invention compared with prior art; Have 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, link is convenient, and applicability is strong.
Outer wall that binds round in said socket and fastening being meant and the circular cone table top of the inwall of outer hoop for mutual coupling, and the circular cone table top is provided with the sawtooth that interior hoop and outer hoop can be tightened.Hoop was good with outer banding solidity in such structure made.
Hoop constitutes for being spliced into a circle by two semicircles in said.Constitute interior hoop by two semicircles and both can realize that the stake that interior hoop is enclosed within two preformed piles connects the periphery, position, can prevent the discontinuity that too much causes owing to arc part again.
The inner ring of said interior hoop is provided with two radial protrusion rings, and said each stake that needs stake to connect preformed pile connects the periphery, position and is respectively arranged with a groove that mates with the radial protrusion ring.The cross sectional shape of said radial protrusion ring is a rectangle.Said groove is positioned at the contact site of preformed pile upper head plate and pile body.Such structure can make between two preformed piles connect more firm.
Description of drawings
Shown in the drawings is the schematic cross-section of preformed pile pile extension structure of the present invention.
Wherein: 1, interior hoop; 2, outer hoop; 3, sawtooth; 4, radial protrusion ring; 5, groove; 6, end plate; 7, pile body.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is made further detailed description.
As described in accompanying drawing, preformed pile pile extension structure of the present invention comprise be socketed in stake that two need stakes connect preformed pile connect position peripheral interior hoop 1, socket and be fastened in the peripheral outer hoop 2 of hoop 1.In hoop 1 constitute for being spliced into a circle by two semicircles, the inner ring of interior hoop 1 is provided with two radial protrusion rings 4, each stake that needs stake to connect preformed pile connects the periphery, position and is provided with one the groove 5 that mates with radial protrusion ring 4 is arranged.The outer wall of interior hoop 1 is the circular cone table top of mutual coupling with the inwall of outer hoop 2, and the circular cone table top is provided with the sawtooth 3 that interior hoop 1 and outer hoop 2 can be tightened.In on hoop 1 the circular cone table top crown direction of sawtooth 3 be partial to the circular cone table top than larger diameter side.In the stake that is provided with 4, two preformed piles of two radial protrusion rings of hoop 1 inner ring connect the periphery, position and be respectively arranged with a groove 5 that mates with radial protrusion ring 4.The cross sectional shape of radial protrusion ring 4 is a rectangle.Groove 5 is positioned at the contact site of preformed pile upper head plate 6 and pile body 7.
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.
