Description

Be used for syndeton of pull-out resistant pile foundation and attaching method thereof
Technical field
The present invention relates to a kind of syndeton that is used for pull-out resistant pile foundation; The invention still further relates to a kind of method that adopts this syndeton to connect uplift pile.
Background technology
Along with the raising of the significance level of modern building and the continuous increase of building height, supporting capacity to ground is had higher requirement, natural ground can better not born the load that upper building transmits, and use concrete pile to do the foundation pile of ground, with pile press stake being pressed into becomes foundation pile after underground, allows foundation pile top carrying building.The concrete pipe pile foundation of building construction in the past mainly bears the vertical compression load, but present many pile foundations then will be born vertical compression load and vertical drawing load simultaneously.More existing in recent years engineerings require to reduce under the pressure promotion of construction costs the owner, and pile tube is used as uplift pile.Being used for the pile tube of resistance to plucking engineering at present because joint is connected to the electric welding welding, and there is certain potential safety hazard in this kind welding manner, mainly is that the welding of tubular pile head place end plate and end plate exists potential safety hazard.Be construction quality problem on the one hand.Because on-the-spot pile foundation construction unit and personnel's level difference causes the mass discrepancy of pile crown and pile crown welding bigger, the quality of welding quality directly influences the use of uplift pile, causes potential safety hazard to engineering.This on the other hand welding manner required time is bigger, has influenced the progress of engineering, increases constructor's workload simultaneously.Because after pile crown and the pile crown welding, need can carry out pile sinking after the problem cooling at 10~15 minutes places to be welded, wasted a large amount of time, influenced the efficient of construction.Many pile foundation construction personnel do not wait the weld cooling just to continue pile sinking simultaneously, have reduced the quality of welding.
Summary of the invention
The objective of the invention is in order to overcome weak point of the prior art, provide a kind of simple in structure, can make fixedly connected fast, the safe and reliable syndeton of two uplift piles;
Another object of the present invention is for a kind of method that adopts above-mentioned syndeton to connect two uplift piles is provided.
In order to achieve the above object, the present invention adopts following scheme:
A kind of syndeton that is used for pull-out resistant pile foundation, comprise the square endplate that is fixedly installed on respectively on the two square resistance to plucking pile crowns, outside two square endplates of square resistance to plucking pile crown joint, be arranged with a plurality of bar shaped mechanical connection cards, thereby described bar shaped mechanical connection cartoon is crossed a plurality of screw and is connected and makes on the square endplate up and down that two uplift piles link together.
The aforesaid syndeton that is used for pull-out resistant pile foundation, it is characterized in that described square endplate comprises a square Plate with web, be provided with a plurality of end to end companies on outside being provided with on the described square Plate with web outside and bind round plate, described company binds round plate and is connected step with square Plate with web outward flange formation one, in the middle of described square Plate with web, be provided with the pile extension mouth, bind round in described company and be provided with the connection screw on the plate.
The aforesaid syndeton that is used for pull-out resistant pile foundation, it is characterized in that described bar shaped mechanical connection card comprises bar shaped card body, on described bar shaped card body, be provided with a strip groove that can be connected on upper and lower two square endplates, about described strip groove, be provided with a plurality of connecting holes on the bar shaped card body at two ends.
The aforesaid syndeton that is used for pull-out resistant pile foundation is characterized in that being evenly equipped with a plurality of holes that are connected that are used for connecting reinforcement on described square Plate with web.
The aforesaid syndeton that is used for pull-out resistant pile foundation, it is characterized in that the described hole that is connected comprises a screw stretch-draw hole and a heavy muscle hole, be provided with the muscle groove between described screw stretch-draw hole and heavy muscle hole, its head of reinforcing bar inserts behind screw stretch-draw hole hoop and passed the muscle groove and be stuck in then on the heavy muscle hole.
The aforesaid syndeton that is used for pull-out resistant pile foundation is characterized in that being provided with collar apertures in described the company on the garter spring, can be provided with steel hoop on described collar apertures.
The aforesaid syndeton that is used for pull-out resistant pile foundation is characterized in that described bar shaped mechanical connection card is four.
A kind of method that adopts above-mentioned syndeton to connect pull-out resistant pile foundation of the present invention is characterized in that may further comprise the steps:
A, on its head of uplift pile, circular end plate is set;
Before B, the pile extension, drawn the perpendicular positioning line at its connection screw center of square endplate at upper and lower two pile crowns, the perpendicular positioning line at pile crown place aligns mutually about making during pile extension, guarantees the connection screw alignment mutually up and down on two square endplates simultaneously;
C, square endplate and bar shaped mechanical connection card are cleaned out, and checked the smooth of square endplate end face with hairbrush;
D, bar shaped mechanical connection card is blocked on the connection step of two pile head end plates, adjust the position of bar shaped mechanical connection card, connecting hole on the bar shaped mechanical connection card is alignd with the screw that is connected on the end plate, then connecting hole be connected screw on the screw of screwing on reinforce, make fixedlying connected between concrete pile and the stake.
In sum, beneficial effect of the present invention:
Utilize the method for the invention can guarantee the quality that pull-out resistant pile foundation connects, improved the concrete pile construction quality, effectively avoid the generation of engineering safety accident, significantly reduce engineering safety hidden danger.
And at present concrete pile with between to be connected be at the scene to welding between end plate on the concrete pile and the end plate, because there are certain difference in limitation of field condition and site operation person's operant level, the quality of welding quality directly influences the use of uplift pile, can't guarantee the quality of weld seam, thereby make the concrete pile in the soil have certain engineering safety hidden danger.Simultaneously present this weld seam connected mode required time is bigger, has influenced the progress of engineering, increases constructor's workload simultaneously.Because after pile crown and the pile crown welding, need can carry out pile sinking after the problem cooling at 10~15 minutes places to be welded, wasted a large amount of time, influenced the efficient of construction.
Show that with observation mechanical connection method of the present invention is feasible by a plurality of field engineering practices.The bonding strength of the concrete pile of finishing by this mechanical connection method meets the demands, and required time is less simultaneously, does not need welding, the spent time is 2~3 minutes, finish connection after, can continue pile sinking, do not need to wait for the regular hour, saved the pile extension time greatly.
