Description
Technical field
The present invention relates to a kind of mechanical connecting structure for pull-out resistant pile foundation; The invention still further relates to a kind of method that adopts this mechanical connecting structure to connect uplift pile.
Background technology
Along with the raising of significance level and the continuous increase of building height of modern building, 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, stake is pressed into after underground and becomes foundation pile with pile press, allow foundation pile top carrying building.The concrete pipe pile foundation of building construction in the past mainly bears vertical compression load, but current many pile foundations will be born vertical compression load and vertical drawing load simultaneously.More existing engineerings require to reduce under the pressure promotion of construction costs owner in recent years, and pile tube is used as uplift pile.The current pile tube for resistance to plucking engineering is because joint is connected to electric welding, and this kind of welding manner exists certain potential safety hazard, is mainly that tubular pile head place end plate and end plate welding exist potential safety hazard.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 larger, the quality of welding quality directly affects the use of uplift pile, causes potential safety hazard to engineering.This welding manner required time is larger on the other hand, has affected the progress of engineering, increases constructor's workload simultaneously.Because after the welding of pile crown and pile crown, can carry out pile sinking after needing the problem at 10-15 minute place to be welded cooling, waste a large amount of time, affect the efficiency of construction.Many pile foundation construction personnel do not wait the cooling pile sinking that just continues of weld simultaneously, have reduced the quality of welding.
Summary of the invention
The object of the invention is in order to overcome weak point of the prior art, provide a kind of simple in structure, can make two uplift piles be fixedly connected with fast, safe and reliable mechanical connecting structure;
Another object of the present invention is for a kind of method that adopts above-mentioned mechanical connecting structure to connect two uplift piles is provided.
In order to achieve the above object, the present invention adopts following scheme:
A kind of mechanical connecting structure for pull-out resistant pile foundation, comprise the circular end plate being fixedly installed on respectively on two resistance to plucking pile crowns, be arranged with multiple arc mechanical connecting clamps outward in two circular end plate of resistance to plucking pile crown joint, thereby described arc mechanical connecting clamp is fixedly connected in circular end plate upper and lower two uplift piles is linked together by multiple screws.
A kind of mechanical connecting structure for pull-out resistant pile foundation as above, it is characterized in that described circular end plate comprises a circular Plate with web, the company's of being provided with garter spring on described circular Plate with web outside, described company's garter spring and circular Plate with web outward flange form an outer ring step, in the middle of described circular Plate with web, be provided with pile extension mouth, on described company's garter spring, be provided with connecting screw hole.
A kind of mechanical connecting structure for pull-out resistant pile foundation as above, it is characterized in that described arc mechanical connecting clamp comprises arc card, in described arc card, be provided with an arc groove that can be connected in upper and lower two circular end plate, in the arc card at the described upper and lower two ends of arc groove, be provided with multiple connecting holes.
A kind of mechanical connecting structure for pull-out resistant pile foundation as above, it is characterized in that being evenly equipped with multiple holes that are connected for connecting reinforcement on described circular Plate with web, the described hole that is connected comprises a screw stretch-draw hole and a heavy muscle hole, between described He Chenjin hole, screw stretch-draw hole, be provided with muscle groove, after behind its head insertion screw stretch-draw hole of reinforcing bar, hoop passes muscle groove, be stuck on heavy muscle hole, on described company's garter spring, be provided with collar apertures, in described collar apertures, can be provided with steel hoop.
A kind of mechanical connecting structure for pull-out resistant pile foundation as above, is characterized in that described arc mechanical connecting clamp is three.
The method that the present invention adopts above-mentioned mechanical connecting structure to connect two uplift piles comprises the following steps:
A, on its head of uplift pile, circular end plate is set;
Before B, pile extension, pull perpendicular positioning line at its connecting screw hole center of circular end plate of upper and lower two pile crowns, when pile extension, make the perpendicular positioning line at upper and lower pile crown place mutually align, guarantee the connecting screw hole alignment mutually up and down in two circular end plate simultaneously;
C, circular end plate and arc mechanical connecting clamp are cleaned out with hairbrush, and checked the smooth of circular end plate end face;
D, arc mechanical connecting clamp is blocked on the outer ring step of two pile head end plates, adjust the position of arc mechanical connecting clamp, connecting hole on arc mechanical connecting clamp is alignd with the connecting screw hole on end plate, then the screw of screwing on connecting hole and connecting screw hole is reinforced, and makes being fixedly connected with between concrete pile and 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 concrete pile construction quality, effectively avoid the generation of engineering safety accident, greatly reduce engineering safety hidden danger.
And being connected between current concrete pile and stake is at the scene to welding between the end plate on concrete pile and end plate, because restriction and site operation person's operant level of field condition exist certain difference, the quality of welding quality directly affects the use of uplift pile, cannot guarantee the quality of weld seam, thereby make the concrete pile in soil have certain engineering safety hidden danger.Simultaneously current this weld seam connected mode required time is larger, has affected the progress of engineering, increases constructor's workload simultaneously.Because after pile crown and pile crown welding, after the problem at 10 1 15 minutes places to be welded of needs is cooling, can carry out pile sinking, waste a large amount of time, affect the efficiency of construction.
Show with observation by multiple field engineering practices, mechanical connection method of the present invention is feasible.The bonding strength of the concrete pile completing by this mechanical connection method meets the demands, and required time is less simultaneously, does not need welding, the spent time is 2 one 3 minutes, completes after connection, can continue pile sinking, do not need to wait for the regular hour, greatly saved the pile extension time.
