Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is illustrated.
The present invention discloses a kind of positioner combined steel formwork bored concrete pile, including pile foundation positioner and connection first
Steel form 3 on the positioning device, bored concrete pile casting concrete and vibrating from steel form is molded with.Positioner bag
Include：Locating support 1, locating support includes framework, and die plate locating holes 31 are provided with framework；Adjusting screw 2, the one of adjusting screw 2
End fixes on the ground, and the other end is connected with framework；Adjustment silk braid 4, adjustment silk braid 4 is fixed on locating support 1, adjusts silk braid
The internal thread matched with external screw thread on adjusting screw 2 is provided with 4.After adjusting screw and adjustment silk braid coordinate, positioning is can adjust
The height of support 1.The fixed steel form bolt coordinated with die plate locating holes 31 on steel form 3.Also it is provided with locating support 1
Installation of embedded parts hole 5.
In the present embodiment, locating support 1 includes vertical support and stull, and two steel forms are at least connected with stull, if connection
Steel form be two, double positioner combined steel formwork bored concrete pile is formed, because the steel form of two bored concrete piles connects
It is connected in same stull, therefore spacing is uniform between two bored concrete piles and meets the requirements.
In the present embodiment, built-in fitting is U-bolt, and U-bolt passes through installation of embedded parts hole by being bolted in stull,
Therefore built-in fitting absolute altitude is impartial.
The invention also discloses a kind of construction method of positioner combined steel formwork bored concrete pile, the construction method include with
Lower step：
1）Line setting：Follow " by overall to part " principle, it is to avoid the accumulation of setting-out error.First set up the control of whole place
Net, then the control net of each sub- square formation is set up respectively.Finally, survey and set each group of axial line control point, it is desirable to which every group with two timbers
Carry out control stake.The central point of each is marked according to every group of control stake again.Points for attention：Live many appearance are straight over long distances
Connect and use tape measure positioning phenomenon, this way easily causes deviation accumulation, so positioned with tape measure being difficult more than one group.
2）Drilling and borehole cleaning：Machine drilling is selected, drilling key control point is to be accurately positioned, borehole perpendicularity, drilling are deep
Degree and diameter.
Each stake has centre of location point, and drill bit is aligned the centre of location point of each bored concrete pile during drilling, to ensure to bore
Bar perpendicularity；After starting drilling, drilling machine installs protective cap, for controlling drilling rod perpendicularity；Keyhole machine balance in itself
And it is smooth, it is to avoid there is inclined hole, inclined hole.After the completion of drilling, there is surface dust to drop in hole during because of drilling, typically also need to artificial two
Secondary borehole cleaning.During borehole cleaning, if discovery has inclined hole, inclined hole phenomenon, hole is repaired and arrived by the mode that need to be expanded bore dia with special instrument
Position, if deviation is excessive, should tamp rear redrilling by hole.
3）Make steel reinforcement cage：Fabrication of reinforcing cage and the key control point of installation：Reinforcing cage stirrup encrypted area and non-confidential are interval
Away from control；The fastness of steel reinforcement cage colligation.
The characteristics of fabrication of reinforcing cage is that quantities is big, repetitive operation, weakening of quality controlling consciousness.Steel reinforcement cage is made by oneself and has added in scene
Work platform for making.There are hoop reinforcement and non-encrypted area spaced scale on the scaffold tubes chosen on this platform, colligation workman is direct
Directly colligation, both improves operating efficiency after according to scale, stirrup is corresponded, and it also avoid the random colligation of stirrup, causes
The undesirable problem of spacing.Steel reinforcement cage processes the scene of being transported in steel bar meter area, steel reinforcement cage deformation, loose often occurs
Phenomenon.This improvement of problem main points is that colligation point must not leak and tie up, be should be noted that during colligation adjacent colligation point steel wire buckle will into splayed,
To avoid steel reinforcement cage diagonal distortion.
4）Steel reinforcement cage is installed：Steel reinforcement cage installs main key control point is how to ensure steel reinforcement cage thickness of protection tier.
The method generally taken is, during casting concrete, it is found that steel reinforcement cage is attached on template or hole wall, manually goes to correct steel again
Muscle cage location, this method is difficult supervision with control.According to bored concrete pile feature, the steel for ensureing thickness of protection tier has been made
Muscle cage card, steel reinforcement cage card has the endoporus being adapted with steel reinforcement cage external diameter size.This cage card by by steel reinforcement cage card in a template
Heart position, it is ensured that protective layer thickness, also improves operating efficiency.
5）Install pile foundation positioner：Positioner includes：Locating support, locating support includes framework, positioning framework
On be provided with die plate locating holes；Adjusting screw, one end of adjusting screw fixes on the ground, and the other end is threaded；Adjustment silk
Set, adjustment silk braid is fixed on locating support, and the internal thread matched with external screw thread on adjusting screw is provided with adjustment silk braid.
6）Steel form is connected on the pile foundation positioner through steel form bolt：Locating support is according to setting
Meter is required to fix spacing between each pile foundation and formed, and the hole of fixed form and built-in fitting is reserved on locating support.Apply
In man-hour, first support can be fixed in pre-drilled stake holes by adjusting screw and flitch, then by steel shutterings mounted in positioning
On support, if find that indivedual stake holes are corresponding with steel form not going up, this hole You Pian holes phenomenon is can determine that substantially, after the completion of need to repairing,
Next procedure is carried out again.After model sheetinstallat is finished, pre-embedded bolt is installed, should be noted that bolt leakage size should be unified and meet design
And code requirement.Finally, whole group absolute altitude is adjusted.According to two control lines, by way of adjusting screw, it is ensured that corner and centre
Unified absolute altitude is all kept with line, adjusting screw is just fixed.
7）Casting concrete：Under the premise of concrete raw material quality in itself is controlled, scene is focused on for concreting
Emphasize vibrating for concrete.
After pile foundation form removal, honeycomb, pitted skin substantial majority because vibrate it is not in place caused by.Concrete vibrating one is
GPRS vibrating method, vibrating spear is quickly stretched pile foundation bottom, is slowly pulled up.Two is control vibrating time；Vibrate continuity
Time, should make concrete not in up effervescent, surface is presented laitance and not untill when sinking.
8）The dismounting of pile foundation positioner and the maintenance of concrete：Form removable principle：Concrete strength ensures its table
Face, corner angle are not damaged because of form removal, just dismountable.Concrete curing is typically conserved using cover film, it is desirable to be its outer surface
Parcel should all be covered tight, and answer and have condensate in protective film.Curing time is divided into according to the difference using cement type
Less than 7 days and must not must not be less than 14 days.
Certainly, described above not limitation of the present invention, the present invention is also not limited to the example above, the art
Change, remodeling, addition or replacement that those of ordinary skill is made in essential scope of the invention, fall within guarantor of the invention
Shield scope.
