Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.Therefore, below to attached
The detailed description of the embodiments of the present invention provided in figure is not intended to limit the range of claimed invention,
But it is merely representative of the selected embodiment of the utility model.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, belongs to the model of the utility model protection
It encloses.
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model is further described with specific embodiment below with reference to accompanying drawings.
As shown in Figure 1-3, a kind of post-tensioning pile composite foundation of the utility model embodiment, including pile body 1 and it is located at pile body 1
The bottom of the structure base slab 2 at top, the structure base slab 2 is laid with mattress layer 3, and muscle is arranged between the pile body 1 and structure base slab 2
Body, muscle body are preferable at the center that pile body 1 is arranged in, and the quantity of muscle body can be multiple.It is located at the portion in pile body 1 on the muscle body
It is divided into lower muscle body 4, the outer sheath of the lower muscle body 4 is installed with lower disrance sleeve 5, is located at mattress layer 3 and structure on the muscle body
Part in bottom plate 2 is upper muscle body 6, and the outer sheath of the upper muscle body 6 is installed with disrance sleeve 7, the bottom end of the lower muscle body 4
Equipped with bottom anchorage 8, the top of the upper muscle body 6 is equipped with top anchorage 9.
The lower muscle body 4 and the junction setting middle part anchorage 10 of upper muscle body 6 and the sealing off and covering anchorage body 11 of covering middle part anchorage 10,
Sealing off and covering anchorage body 11 can prevent the corrosion of middle part anchorage 10, can be by the tensioning work of muscle body relative to this structure in traditional construction technology
Skill is placed on before pouring sole plate, and stake top position directly applies straight up pre- after 1 intensity of pile body reaches design requirement
Stress avoids stretching construction and intersects with sole plate construction technology, and the concrete without sole plate reaches intensity requirement
Waiting time further improves construction efficiency.
Apply prestressing force at the top of pile body 1, the driven stake top of uplift force impetus for being subject to pile body 1 is transferred to pile body
1 bottom plays 1 side soil frictional resistance of pile body as the load increases and gradually from bottom to up, can give full play to 1 side of pile body soil
Frictional resistance, and pile body 1 has been applied prestressing force, and entire pile body 1 can be made to be in pressured state.Due to traditional resistance to plucking pile body 1
Uplift force acts on stake top position, and whole pile body 1 is in tension state, and pile body 1 is caused to be also easy to produce crack, and this structure makes pile body 1
At pressured state, the drawbacks of tension for solving traditional pile body 1 is also easy to produce crack.
The top of the mattress layer 3 is laid with plain concrete layer 12, and the top of the plain concrete layer 12 is laid with waterproof layer 13,
Between the waterproof layer 13 and upper muscle body 6 be equipped with seal ring 14, plain concrete layer 12 can smooth mattress layer 3 upper surface, make to tie
The bottom uniform force of structure bottom plate 2 improves the support stability of entire mattress layer 3.
The top anchorage 9 is equipped with metal cap 15, is equipped with the row moved up and down for top anchorage 9 in the metal cap 15
Journey space 16.When post-tensioning pile composite foundation plays resistance to compression function, since mattress layer 3 mostly uses rubble, aggregate chips, sand, flyash
Equal materials, pressure cross conference squeeze mattress layer 3 deformation occurs, the bottom for changing structure base slab 2 supports distribution of force, makes muscle body
Stress at 3 position of mattress layer is concentrated, therefore upper disrance sleeve 7 is arranged on the outside of upper muscle body 6, and be arranged on top anchorage 9
Metal cap 15, if structure base slab 2 is pressurized, muscle body has certain mobile space in the stroke space 16 in metal cap 15,
To solve the problems, such as that muscle body is broken, bends because stress is concentrated.
The top anchorage 9 includes billet 17 and bolt-nut 18, and the billet 17 supports metal cap 15 and anchoring
Nut 18, the bolt-nut 18 are fixed on muscle body 6, and the bolt-nut 18 is located in metal cap 15, and metal cap 15 is detained
On billet 17.
The bottom anchorage 8 is the downward taper structure of arrow, when 1 anti-plug of pile body of construct is placed in muscle body structure from
To positioning and guiding function, and reduce resistance when merging.
When the post-tensioning pile composite foundation is constructed, pile body 1 of constructing first, the pile body 1 is mostly rigid pile body 1, then by band
In the lower muscle body 4 merging pile body 1 of lower disrance sleeve 5, when the intensity of pile body 1 reaches requirement, muscle body is applied at 1 top of pile body
Locking middle part anchorage 10, is then laid with mattress layer 3 at the top of pile body 1 after prestressing force, finally at the top of the installation of the top of upper muscle body 6
Anchorage 9, pouring structure bottom plate 2 realize the anchor connection of post-tensioning stake and structure base slab 2, form post-tensioning pile composite foundation.
Finally, it should be noted that above-described each embodiment is merely to illustrate the technical solution of the utility model, rather than
It is limited；Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art
It is understood that it can still modify to technical solution documented by previous embodiment, or to part of or whole
Technical characteristic is equivalently replaced；And these modifications or substitutions, it does not separate the essence of the corresponding technical solution the utility model
The range of each embodiment technical solution.
