Abstract
The invention discloses a precast pile splicing connector which comprises a hoop (1) with the same shape of the section of a precast pile, and is characterized in that an inward contracting opening (2) is formed in the top end of the hoop (1). The precast pile splicing connector is simple to manufacture, firm to connect, convenient to construct, and low in cost, and has a high application value and a high promotion value.
Description
Technical field:
The present invention relates to a kind of preformed pile pile extension connector, belong to the building pile foundation engineering technical field.
Background technology:
At present, the connected mode of concrete precast pile has many kinds, connects as end plate welding or the bolt of pile tube by the stake two ends; Precast concrete square pile is by connecting with sulphide mastic at stake end reserved steel bar and concrete hole, or is welded to connect with angle steel and steel plate by pre-buried steel hoop.These connected modes or construction complexity or cost height have certain technical limitation.The steel hoop of the steel hoop connected mode of prior art does not have to close up in the position, end, thereby two when butt joint joint stake do not form butt joint and welding job face, can not connect two joint stakes up and down by direct welding, it can only be by waiting to connect two joint stakes up and down at steel hoop external welding angle steel or steel plate, this link technique waste material, construction is slow, and pile extension efficient is low.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of making simple, be connected firmly, easy construction, cost is low, it is reliable for effect to connect, save material, and construction is fast, the preformed pile pile extension connector that pile extension efficient is high.
Purpose of the present invention can reach by following measure: a kind of preformed pile pile extension connector, it comprises the cuff identical with the preformed pile section form, it is characterized in that the top of cuff is provided with interior closing in.
In order further to realize purpose of the present invention, described interior the closing in forms the interior closing in littler than preformed pile cross section to oblique interior receipts of preformed pile end.
In order further to realize purpose of the present invention, close up in described to receive in the preformed pile end to form and close up in isoplanar with the stake end.
In order further to realize purpose of the present invention, described cuff inboard is provided with steel plate.
In order further to realize purpose of the present invention, described cuff inboard is provided with steel bar.
In order further to realize purpose of the present invention, each side of described cuff is equipped with a steel plate or a steel bar.
In order further to realize purpose of the present invention, the length of described cuff is 0.01-1m.
The present invention can produce following good effect compared with the prior art: the present invention receives formation butt joint and welding job face by steel hoop in the stake end, can make two joint stakes dock easily and weld, and has saved engineering time and construction costs.The sulphide mastic connected mode of contrast prior art is made simple, and easy construction connects reliable for effect; Steel hoop connected mode than prior art is saved connecting angle and steel plate, and it is fast to construct during joint material joint, pile extension efficient height, and the coupling part sealing is corrosion-resistant; More existing end plate connected mode connects reliable for effect, and forms the constraint of horizontal axle center at the stake end and make anti-the impacting of stake end.This preformed pile connector inboard is welded with steel plate or steel bar again, has just more strengthened this connector and the concrete reliability that is connected of pile body, has further improved the fastness that be connected of this connector with stake, makes the connection of two joint stakes more solid and reliable.

The specific embodiment: preferred forms of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment 1: a kind of preformed pile pile extension connector is (referring to Fig. 1-Fig. 3), it comprises cuff 1, the section form of this cuff 1 is identical with the section form of preformed pile 4, the length of cuff 1 is 0.01-1m, stressing conditions after concrete length connects according to stake determines that stake is stressed few, and the length of cuff 1 is just short, stake is stressed big, and the length of cuff 1 is just long.
Receive in the top of cuff 1 is oblique to the preformed pile end and form the interior closing in 2 littler than preformed pile cross section.Cuff 1 is connected with the interior reinforcing cage 3 of prefabricated pile body, during pile extension, and the preformed pile pile extension connector of stake butt joint up and down, 2 places that close up in the preformed pile pile extension connector have just formed butt joint and welding job face, weld the butt joint of having finished two joint stakes once enclosing along the docking port place.
Embodiment 2: (referring to Fig. 4-Fig. 6), its structure and principle be substantially with embodiment 1, and the top that its difference is cuff 1 is received in the preformed pile end to form and closed up 2 in isoplanar with the stake end for a kind of preformed pile pile extension connector.Present embodiment is than embodiment 1, and to be plane and interior receipts area big than closing up in oblique among the embodiment 1 because of the interior closing in of pile extension device, and butt joint is comparatively convenient during pile extension.
Embodiment 3: a kind of preformed pile pile extension connector (referring to Fig. 7, Fig. 8), its structure is substantially with embodiment 1, and its difference is in described cuff 1 inboard and is provided with steel plate 6, strengthens this steel hoop and is connected with pile body is concrete, each side can be provided with one, symmetrically.
Embodiment 4: a kind of preformed pile pile extension connector (referring to Fig. 9, Figure 10), its structure is substantially with embodiment 2, and its difference is in described cuff 1 inboard and is provided with steel bar 5 and steel plate 6, strengthens this steel hoop and is connected with pile body is concrete, each side can be welded with one, symmetrically.
Can be provided with steel plate 6 and steel bar 5 simultaneously in the above-mentioned cuff 1 as required, can be provided with steel plate 6 in two relative sides, two relative sides are provided with steel bar 5 in addition.
Above embodiment is described preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
