Abstract
The invention discloses an uplift pipe pile and a connection method for the uplift pipe pile and a foundation bottom plate. The uplift pipe pile is characterized in that a pile head of a concrete pipe pile is provided with multiple sleeves in screwed connection with anchor steel bars, and the anchor steel bars are pre-buried in the concrete pipe pile after being in screwed connection with internal threads of the sleeves; and the concrete pipe pile and uplift steel bars of the foundation bottom plate are in screwed connection through the sleeves to form a pile foundation of the uplift pipe pile. Compared with the prior art, the working procedure of pile cutting construction is omitted, the construction that uplift treatment is carried out after the pile head is broken after pile sinking is completed is effectively replaced, the practical pile usage length is reduced, the construction difficulty is lowered, the on-site construction period is shortened, and therefore the material purchasing cost and the construction cost are saved; and the uplift pipe pile is particularly suitable for being applied and popularized in a pile foundation project with uplift requirements.
Description
Technical field
The present invention relates to pre-cast pipe pile technical field, a kind of anti-pulling pipe piles and with sole plate
Method of attachment.
Background technology
Along with the development of China's building trade, underground space building application is more and more extensive, and large-area applications has resistance to plucking
The pile foundation engineering required also gets more and more.At present, anti-pulling pipe piles the most all uses the method cutting stake to be connected with sole plate, cuts
Pile driving construction is on the basis of ensureing design effective length, and the pile tube that reserved stake top is divided, when being connected with sole plate by this portion
It is in charge of the concrete amputation of stake, retains deformed bar and pile crown end plate, then carry out pile tube and be connected with sole plate.
Cutting pile three unfavorable factors of existence of prior art: first, add the pile tube consumption of actual consumption, increase
The cost of processed materials purchased；Second, work progress increases pile driving engineering amount, increases cutting pile quantities after pile sinking, increase
Construction cost, extends construction period；3rd, the pile body integrity in below stake face of cutting should be ensured during cutting stake, again
Retaining pile crown end plate and cut stake partial prestressing reinforcing bar, difficulty of construction is the biggest.
Summary of the invention
It is an object of the invention to provide a kind of anti-pulling pipe piles and the company with sole plate thereof for the deficiencies in the prior art
Connecing method, use tube pile structure and the sole plate method of screwed connection anti-punching shear bar of pile crown embedded sleeve barrel, sleeve is by anchor
Gu steel bar preassembling is embedded in pile tube, the anti-punching shear bar of anchor bar and sole plate is all with screw thread with the sleeve being embedded in pile tube even
Connect, not only reduce the difficulty of construction that resistance to plucking processes, shorten the duration, but also reduce making and the construction cost of pile tube,
Overall structure is good, can be widely applied to the pile foundation engineering of anti-pulling pipe piles, has that stock utilization is high, processing technology simple, executes
The advantage that work speed is fast and construction costs is low.
The object of the present invention is achieved like this: a kind of anti-pulling pipe piles, including by pile crown end plate, deformed bar and fill out
The concrete tubular pile that in-core joint bar is prefabricated, is characterized in that the pile crown of concrete tubular pile is provided with several and anchor bar screwed connection
Sleeve, described anchor bar is embedded in concrete tubular pile by after the female thread screwed connection of sleeve；Described sleeve vertically sets
Put under pile crown end plate, and the port of sleeve is concordant with pile crown end plate.
A kind of method of attachment of anti-pulling pipe piles and sole plate, including using the pile foundation of anti-pulling pipe piles under sole plate, its
Feature is the pile foundation that concrete tubular pile is anti-pulling pipe piles that sole plate uses embedded sleeve barrel, and described concrete tubular pile is by sleeve
Female thread becomes the pile foundation of anti-pulling pipe piles with the anti-punching shear bar screwed connection of sole plate.
The present invention compared with prior art decreases cutting piles operation, effectively instead of after crushing pile crown after pile sinking completes
Make the construction that resistance to plucking processes, decrease actual pile length, reduce difficulty of construction, shorten the cycle of site operation, thus
Save the cost of processed materials purchased, construction cost, be particluarly suitable for there are popularization and application in the pile foundation engineering of resistance to plucking requirement.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is Fig. 1 top view；
Fig. 3 is that the present invention specifically uses schematic diagram；
Fig. 4 is sleeve and anti-punching shear bar and anchor bar connection diagram.
Detailed description of the invention
Refering to accompanying drawing 1～accompanying drawing 2, the present invention is by pile crown end plate 1, sleeve 2, deformed bar 9 and to fill out in-core joint bar 4 prefabricated
Concrete tubular pile 5, pre-buried five sleeves 2 being provided with female thread 6 on the pile crown of described concrete tubular pile 5, sleeve 2 is a length of
100mm and be screwed connection by female thread 6 and anchor bar 3；After described anchor bar 3 is by female thread 6 screwed connection of sleeve 2
It is embedded in the pile body of concrete tubular pile 5；Described sleeve 2 is vertically set on pile crown end plate 1 time, and the port of sleeve 2 and pile crown
End plate 1 is concordant, and carries out labelling on the pile crown end plate 1 of embedded sleeve barrel 2.
Refering to accompanying drawing 3～accompanying drawing 4, the present invention is performed such anti-pulling pipe piles construction: marked by above-mentioned embedded sleeve barrel 2 of carrying out
The concrete tubular pile 5 of note sit up straight as the direct pile sinking in stake top, when concrete tubular pile 5 is with basis floor 7 connection construction, by 25mm
Anti-punching shear bar 8 tapping hot-rolled ribbed for HRB500 become the silk tooth of 20mm, silk dental length is 50mm, directly be embedded in pile body
Female thread 6 screwed connection of sleeve 2.The present invention is embedded with the sleeve 2 of female thread 6, pipe of concrete during prefabricated tubular pile in advance
Stake 5 uses the pull-out resistant pile foundation on floor 7 based on sleeves 2 and the mode of anti-punching shear bar 8 screwed connection, instead of after pile sinking completes
The form of construction work that resistance to plucking processes made by broken pile crown, decreases cutting piles operation, thus is effectively shortened the cycle of site operation,
Greatly reduce difficulty of construction, decrease actual pile length, saved the cost of processed materials purchased and construction cost, be particluarly suitable for
Have in the pile foundation engineering of resistance to plucking requirement and apply.
More than simply the present invention is further illustrated, and is not used to limit this patent, all implements for equivalence of the present invention,
Within being intended to be limited solely by the right of this patent.
