The invention discloses a connection mechanism between a concrete prefabricated pile and a pile foundation bearing platform. There is a sleeve, the inner wall of the sleeve is provided with threads, and the hollow part of the prefabricated pile is provided with a steel cage. The invention is stable in connection with the pile foundation cap, easy to operate, effectively prevents the core from being pulled out, the sleeve is directly welded on one side of the pile core on the end plate, the force is reasonable, the operation is simple, and the end plate mold does not need to be remade. It is necessary to open several anchor holes in the prefabricated pile end plate.
Description
Technical field
The present invention relates to architectural engineering stakes, and in particular to a kind of bindiny mechanism of concrete precast pile and pile foundation support table.
Background technique
Concrete prefabricated hollow pile is used as uplift pile using more and more extensive in practical projects, but prefabricated pile and cushion cap
Connect still problematic presence.Now construction mostly uses concrete to fill out core, is transmitted to buoyancy suffered by cushion cap by wadding weft variation mixed
On solidifying soil prefabricated pile.But due to factors such as site operation environment, causes concrete to fill out core quality and be difficult to ensure, exist and fill out core and pulled out
Danger out.
In addition, there are also the sides for connecting prefabricated pile main reinforcement and cushion cap anchor rib simultaneously using sleeve for the connection of prefabricated pile and cushion cap
Prefabricated pile main reinforcement is located in sleeve by method, this method, is unfavorable for applying prestressing force to prestressed concrete prefabricated pile.And prefabricated pile
During stake processed, since main reinforcement is longer, it is more difficult that main reinforcement is located at the construction in sleeve.
Summary of the invention
Goal of the invention: the object of the present invention is to provide the bindiny mechanisms of a kind of concrete precast pile and pile foundation support table, solve
The problem of existing prefabricated pile connect inconvenience with pile foundation support table, be easy to cause and fills out core and be pulled out, constructional difficulties.
Technical solution: the bindiny mechanism of concrete precast pile and pile foundation support table of the present invention, including end plate, the end
Plate is located at the top of prefabricated pile, is provided with dowel hole and cage bar holes on the end plate, the end plate side is connected with sleeve, the set
Cylinder inner wall is provided with screw thread, and the prefabricated pile hollow parts are provided with steel reinforcement cage.
The risk that wadding weft variation is pulled out is effectively reduced, the telescopic screw is connected with anchor bar, the anchoring steel
Muscle passes through dowel hole and connect with pile foundation support table.
Facilitate transmitting uplift force and construction, the steel reinforcement cage includes filling out core main reinforcement, fill out core stirrup and filling out core bottom plate, described to fill out
Core main reinforcement, which is vertically arranged in, fills out on core bottom plate, it is described fill out core stirrup and be horizontally installed on fill out between core main reinforcement.It is poured in the steel reinforcement cage
It has built concrete and has filled out core.
Core is filled out in order to which superstructure uplift force is passed to concrete, core main reinforcement one end stretching prefabricated pile of filling out is anchored in
In pile foundation support table.
In order to simple to operate, sleeve alignment dowel hole is welded on end plate by pile body side.
The utility model has the advantages that the present invention and pile foundation support table stable connection, easy to operate, it effectively prevent filling out core and is pulled out, sleeve is straight
It connects and is welded on stake core side on end plate, reasonable stress is easy to operate, does not need recasting end plate mold, it is only necessary in prefabricated pile end plate
On open up several dowel holes.
Detailed description of the invention
Fig. 1 is attachment structure schematic diagram；
Fig. 2 is square endplate schematic diagram；
Fig. 3 is circular end plate schematic diagram；
Fig. 4 is reinforced bar sleeve sectional view.
Specific embodiment
Invention is further explained with reference to the accompanying drawing.
As shown in Figs 1-4, the bindiny mechanism of concrete precast pile and pile foundation support table includes concrete prefabricated hollow pile 1, is mixed
It is equipped with end plate 3 at the top of solidifying soil Prefabricated hollow pile 1, end plate 3 is welded with sleeve 4 in stake core side, 31 He of dowel hole is provided on end plate 3
Cage bar holes 32, pre-buried anchor bar 5 in pile foundation support table 2, anchor bar 5 pass through dowel hole 31 and connect with 4 spiral of sleeve, concrete
The hollow parts of Prefabricated hollow pile 1 are provided with steel reinforcement cage 6 and casting concrete fills out core 7, and steel reinforcement cage 6 includes filling out core main reinforcement 61, filling out
Core stirrup 62 and fill out core bottom plate 63.Wherein, sleeve lining is helicitic texture, and anchor bar is spiral.
In using the present invention, firstly, opening dowel hole in advance in end plate and in the stake core side welded sleeve of end plate, work as pile foundation
It will include filling out at the steel reinforcement cage merging hollow pile hollow parts of core bottom plate, then poured to hollow pile hollow parts after the completion of construction
Wadding weft variation will be connected to coagulation with the anchor bar of pile foundation support table connection within the wadding weft variation strength enhancing time
On the prefabricated pile end plate of soil in pre-buried sleeve, to realize the connection of part pile cap steel muscle and prefabricated pile, reach to wadding weft variation
After some strength, pile foundation support table is poured, the final connection for realizing concrete precast pile and pile foundation support table.
