Abstract
The utility model discloses a flange plate for uplift pile foundation, comprising a connecting ring. One end of the connecting ring is provided with a connecting rib board, and the other end of the connecting ring is provided with a tension connection plate. The connecting ring, the connecting rib board and the tension connection plate are tightly fixed into a body, and a plurality of reinforced blocks are uniformly distributed between the connecting rib board and the tension connection plate. The connecting rib board is uniformly distributed with a plurality of combining holes for connecting reinforcing bars, and the tension connection plate is uniformly distributed with a plurality of screw tension connection holes. The purpose of the utility model is to overcome the defects in the prior art. Concrete piles as uplift piles can be used in basic anti-uplift engineering, and the reliability of high pile foundation connection is increased.
Description
Technical field
The utility model relates to a kind of flange that is used for pull-out resistant pile foundation.
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.When the pile tube of being produced at present was used for the resistance to plucking engineering, because the electric welding that is connected at joint end plate place is welded, there was certain potential safety hazard in this kind welding manner, mainly was that the end plate at tubular pile head place and the end plate welding at adjacent studs pile crown place exist 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 the welding of pile crown place end plate and adjacent studs end plate needs 10～15 minutes, need to wait for 10～15 minutes cool time after end plate welds simultaneously and can carry out pile sinking, 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.
The utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, provides a kind of and makes concrete pile can be used as uplift pile to be applied in the basic anti-floating engineering, and improve the reliability that pile foundation connects and make pile foundation realize quick flange connecting dish simultaneously.
In order to achieve the above object, the utility model adopts following scheme:
A kind of flange that is used for pull-out resistant pile foundation, comprise a connecting ring, on described connecting ring one end, be provided with Plate with web, on the described connecting ring other end, be provided with the stretch-draw terminal pad, described connecting ring, Plate with web and stretch-draw terminal pad fasten as one, and are evenly equipped with a plurality of reinforcement blocks between described Plate with web and stretch-draw terminal pad, on described Plate with web, be evenly equipped with a plurality of combination bore that reinforcing bar connects that are used for, on described stretch-draw terminal pad, be evenly equipped with a plurality of screw stretch-draw connecting holes.
Aforesaid a kind of flange that is used for pull-out resistant pile foundation, it is characterized in that described combination bore 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, reinforcing bar inserts screw stretch-draw orifice ring and is connected after passing the muscle groove on the heavy muscle hole.
Aforesaid a kind of flange that is used for pull-out resistant pile foundation is characterized in that being provided with ring-shaped step on the described Plate with web outside.
Aforesaid a kind of flange that is used for pull-out resistant pile foundation is characterized in that can being fixedly connected with steel hoop in described collar apertures.
Aforesaid a kind of flange that is used for pull-out resistant pile foundation is characterized in that described Plate with web is annular Plate with web.
Aforesaid a kind of flange that is used for pull-out resistant pile foundation is characterized in that described stretch-draw terminal pad is annular stretch-draw terminal pad.
In sum, the utility model with respect to its beneficial effect of prior art is:
1, making the concrete pile of being produced can be used as uplift pile is applied in the basic anti-floating engineering.When the concrete pile that is used for the anti-floating engineering need carry out pile extension, as long as connect with the screw of some stretch-draw terminal pad with two pile head places, just can realize concrete pile with between be connected.
2, guarantee concrete pile crown bonding strength, improved the concrete pile construction quality, effectively avoided the generation of engineering safety accident, significantly reduced engineering safety hidden danger.And at present being connected between the end plate of the end plate of concrete pile crown and adjacent pile crown is 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 end plate welding quality directly influences the use of uplift pile.Owing to the restriction of job site condition, can't guarantee the quality of weld seam, thereby make the concrete pile of finishing of constructing have certain engineering safety hidden danger on the other hand.
3, during being connected between concrete pile and the stake, required time is less, does not need welding, does not also need to wait for cool time and can continue pile sinking, as long as the screw of some of screwing between the stretch-draw terminal pad has been saved the time of having constructed.And present end plate connected mode is welding, and required time is more, has influenced the progress of engineering, increases constructor's workload simultaneously.Because the welding of pile crown place end plate and adjacent studs end plate needs 10～15 minutes, after the end plate welding, need can proceed pile sinking after the place to be welded cooling in 10～15 minutes, wasted a large amount of time, influenced the efficient of construction.
4, the stake and the connect hours of stake were controlled at 2～3 minutes, have saved the concrete pile engineering time, accelerated programming to a certain extent.
