Further, above-mentioned bayonet socket block is rectangular block, and projection is vertically located at rectangular block both ends.
Further, above-mentioned two projections are respectively equipped with the shoulder hole corresponding with screwed hole, and namely resilient wedge member is located in shoulder hole.
Further, upper resilient wedge member comprises stepped pin member, is positioned at spring part and the cover plate of pin member head end, and the tail end of described stepped pin member is cammed surface, and spring part is arc elastic sheet.
The quick connecting method of the utility model prestressed concrete pipe pile bayonet socket block formula fast joint structure, described prestressed concrete pipe pile bayonet socket block formula fast joint structure comprises the flange be located on two docking prestressed concrete pipe pile end faces, on two flange end faces, correspondence offers screwed hole, two prestressed concrete pipe piles are laid with the fluting connected with screwed hole on the perisporium of flange, two flutings on described two docking prestressed concrete pipe piles are provided with a bayonet socket block, two projections of bayonet socket block snap in fluting, the inner side that two projections are relative is provided with the resilient wedge member be trapped in two docking prestressed concrete pipe pile screwed holes, during docking, flange that is upper and lower, two pile tubes is mutually close, and the screwed hole of upper and lower pile tube is aligned, thus ensure that the fluting of pile tube is positioned in same lengthwise position, then in fluting, snap in bayonet socket block, namely two resilient wedge member on bayonet socket block are trapped in screwed hole, complete two pile tube docking.
The utility model instead of welding connecting mode by safe and reliable mechanical connection manner, and bayonet socket block, as the main body connecting pile tube, uses 6-22 bayonet socket block annular spread to connect pile tube according to the diameter of pile tube.
Compared with prior art, the beneficial effects of the utility model comprise following some:
1, the bayonet socket block of mechanical connection connects reliable for effect, can meet the requirements such as resistance to plucking, bending resistance, shearing resistance.
2, be mechanically connected time saving and energy saving, need good construction environment by welding, and length consuming time.Bayonet socket block only needs to be pressed into pile tube, greatly raises the efficiency.

detailed description of the invention:
The utility model prestressed concrete pipe pile bayonet socket block formula fast joint structure, comprise the flange 1 be located on two docking prestressed concrete pipe pile K end faces, on two flange end faces, correspondence offers screwed hole 2, two prestressed concrete pipe piles are laid with the fluting 3 connected with screwed hole 2 on the perisporium of flange 1, two flutings 3 on described two docking prestressed concrete pipe piles are provided with a bayonet socket block 4, two projections of bayonet socket block 4 snap in fluting 3, and the inner side that two projections are relative is provided with the resilient wedge member 5 be trapped in two docking prestressed concrete pipe pile screwed holes.
Further, for the ease of operation, above-mentioned bayonet socket block 4 is rectangular block 401, and projection 402 is vertically located at rectangular block 401 both ends.
Further, in order to reasonable in design, above-mentioned two projections are respectively equipped with the shoulder hole 6 corresponding with screwed hole, and namely resilient wedge member 5 is located in shoulder hole 6.
Further, in order to reasonable in design, upper resilient wedge member 5 comprises stepped pin member 501, is positioned at the spring part 502 of pin member head end and cover plate 502, and the tail end of described stepped pin member is cammed surface, and spring part is arc elastic sheet.
The quick connecting method of the utility model prestressed concrete pipe pile bayonet socket block formula fast joint structure, described prestressed concrete pipe pile bayonet socket block formula fast joint structure comprises the flange be located on two docking prestressed concrete pipe pile end faces, on two flange end faces, correspondence offers screwed hole, two prestressed concrete pipe piles are laid with the fluting connected with screwed hole on the perisporium of flange, two flutings on described two docking prestressed concrete pipe piles are provided with a bayonet socket block, two projections of bayonet socket block snap in fluting, the inner side that two projections are relative is provided with the resilient wedge member be trapped in two docking prestressed concrete pipe pile screwed holes, during docking, flange that is upper and lower, two pile tubes is mutually close, and the screwed hole of upper and lower pile tube is aligned, thus ensure that the fluting of pile tube is positioned in same lengthwise position, then in fluting, snap in bayonet socket block, namely two resilient wedge member on bayonet socket block are trapped in screwed hole, complete two pile tube docking.
The utility model instead of welding connecting mode by safe and reliable mechanical connection manner, and bayonet socket block, as the main body connecting pile tube, uses 6-22 bayonet socket block annular spread to connect pile tube according to the diameter of pile tube.
As figure shows, this connection device be used to there are certain requirements pile tube and flange.First must at upper and lower pile tube place fluting, this fluting is used for filling in bayonet socket block, and the size of fluting should meet carries out interference fit with bayonet socket block, secondly, flange is furnished with screwed hole originally, is convenient to coordinate the effect playing fastener buccal mass with resilient wedge member.
Specific operation process is in the groove press-in of bayonet socket block held successfully at upper and lower pile tube in advance with relevant device, the height of bayonet socket block opening just in time equals the thickness of two pieces of flange, in the process of press-in bayonet socket block, the tapered ramp of resilient wedge member while higher than flange, now tapered ramp is subject to a downward power and arc elastic sheet is shunk bayonet socket block can be loaded smoothly.When whole bayonet socket block is filled in the groove of pile tube, whole resilient wedge member also just in time arrives the position of screwed hole in flange, and now resilient wedge member is no longer subject to the pressure of flange, and arc elastic sheet is upheld, and tapered ramp snaps in the screwed hole of flange and restores.The inclined-plane of resilient wedge member snaps in the screwed hole of flange and prevents whole bayonet socket block from sliding.
Compared with prior art, the beneficial effects of the utility model comprise following some:
1, the bayonet socket block of mechanical connection connects reliable for effect, can meet the requirements such as resistance to plucking, bending resistance, shearing resistance.
2, be mechanically connected time saving and energy saving, need good construction environment by welding, and length consuming time.Bayonet socket block only needs to be pressed into pile tube, greatly raises the efficiency.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
