Description

The pre-stressed concrete hollow square stake of band stake point

Technical field

The utility model relates to a kind of concrete pile, particularly a kind of pre-stressed concrete hollow square stake with the stake point.

Background technology

Civil engineering is extensive use of preformed pile, prestressed concrete pipe pile and pre-stressed concrete hollow square stake on ground is handled at present.The solid side's stake of prefabricated reinforced concrete is directly concrete to be filled in the prefabricated reinforcing cage, through the natural curing moulding because employing is manually cast.Its point can with the pile body one-shot forming, but since steel can not autofrettage, defective such as concrete strength is on the low side, waste of material is serious, will be substituted by energy-conservation other the high-strength series products of material that subtract.

Prestressed concrete pipe pile and pre-stressed concrete hollow square stake are batch production production, are by fill concrete in prefabricated reinforcing cage, and through technology such as centrifugal, steam-cured and make, have the energy-conservation high-strength advantage of material that subtracts, and more and more are widely used at present.But this type of stake during fabrication, owing to be subjected to the influence of centrifugal forming, often makes all belt end plates of two ends, the stake point is not made of one with pile body, and install after employing will shift to an earlier date prefabricated concrete pile point mostly.This not only makes troubles to construction, and because installation is not in place, tends to cause pile body out of plumb, displacement, as for phenomenons such as breakage fracture.

Summary of the invention

The utility model provides a kind of simple in structure at the problems referred to above of the prior art, making, easy to use, the vertical one of pile body pile crown, significantly overcome out of plumb, displacement, the breakage defective that fractures, the pre-stressed concrete hollow square stake that has improved the band stake point of city quality of pile effectively.

For achieving the above object, the pre-stressed concrete hollow square stake of the utility model band stake point is concrete hollow side's stake of end band point formula pile crown, and the pile body base portion has the square base end plate that is welded with cuff, pile body and the pile crown joint portion of band center hole to have the length of side to be shorter than the prestressed reinforcement gripper shoe of base portion end plate with the belt transect center hole; The stake side of being divided into, tip platform shape, square platform shape stake point have the sharp end plate of square stake; Link to each other by the prestressed reinforcement cage between base portion end plate and the prestressed reinforcement gripper shoe, the prestressed reinforcement gripper shoe links to each other by prestressed reinforcement cage or steel frame with stake point end plate, and is formed by the concrete once-cast.So design, both convenient manufacturing of pile body skeleton by prestressed reinforcement cage connection base portion end plate and prestressed reinforcement gripper shoe are formed has structural performance preferably again; The prestressed reinforcement gripper shoe links to each other by prestressed reinforcement cage or steel frame with stake point end plate, can both guarantee the pile crown structural strength conscientiously; Pile body that connects as one and pile crown skeleton are formed by the concrete once-cast, have stronger overall structure performance.Therefore, it has simple in structure, making, easy to use, and the vertical one of pile body pile crown does not exist installation not in place, causes pile body out of plumb, displacement, as for phenomenons such as breakage fracture, effectively improves the advantage of pile foundation quality.

As optimization, pile body partly has manhole, and pile crown partly has the conical blind hole that communicates with the pile body manhole; The base portion end plate is connected with the sharp end plate of stake by the many equally distributed prestressed reinforcements that pass the prestressed reinforcement gripper shoe.So design, pile body partly has manhole, and pile crown partly has the conical blind hole that communicates with the pile body manhole, can guarantee structural strength, can alleviate the pile body deadweight again as much as possible.The base portion end plate is connected with the sharp end plate of stake by the many equally distributed prestressed reinforcements that pass the prestressed reinforcement gripper shoe, and pile body and pile crown be firm and support with the integral type prestressed reinforcement, and overall construction intensity is better, more convenient manufacturing.

As optimization, the described prestressed reinforcement that passes the prestressed reinforcement gripper shoe is 8, and wherein each middle part, one, every limit, place, four angles is each one; Be shaped on the reinforcing bar through hole on the prestressed reinforcement gripper shoe, the base portion end plate is shaped on the reinforcing bar through hole that a corresponding with it side has the reinforcing bar draw-in groove, also is shaped on the reinforcing bar through hole that the reinforcing bar draw-in groove is arranged in the circumferential equally distributed outside that is harmonious with it on the sharp end plate of stake.So design, the described prestressed reinforcement that passes the prestressed reinforcement gripper shoe is 8, and wherein each middle part, one, every limit, place, four angles is each one, and prestressed reinforcement is in the operation at stake point end plate place when then making with the least possible prestressed reinforcement is more convenient.Two ends have the reinforcing bar through hole of reinforcing bar draw-in groove then to make things convenient for tension reinforcing steel bar and fixedly allow reinforcing bar pass through through hole during the steel tension reinforcing steel bar, fixedly just reinforcing bar are clamp-oned in the draw-in groove during reinforcing bar, and the outer end reinforces clamp, cuts very convenient use again after maintenance is good.After reinforcing bar was clamp-oned draw-in groove, the through hole of vacating also can be used for being connected and fixed a top of a most advanced and sophisticated front edge of board, with other side's stake that links to each other with the base portion end plate, and promptly can the plug-in mounting alignment pin.

As optimization, the sharp end plate of stake also is shaped on center screw or through hole.So design, the top of more convenient equipped pile crown end.

As optimization, between base portion end plate and the prestressed reinforcement gripper shoe except that the main prestressed reinforcement by the sharp end plate of above sensible stake links to each other, also link to each other with the secondary prestressed reinforcement of prestressed reinforcement gripper shoe by the base portion end plate that is connected: prestressed reinforcement gripper shoe and stake point end plate is except that the main prestressed reinforcement by sensible base portion end plate links to each other, and is also continuous by steel frame.So design can improve overall construction intensity greatly.

As optimization, described reinforcing cage is formed by connecting by many axial prestress reinforcing bar and spiral reinforcements arranged side by side.So design, structural performance is better.

After adopting technique scheme, the pre-stressed concrete hollow square stake of the utility model band stake point has simple in structure, make easy to use, the vertical one of pile body stake point, can improve overall construction intensity greatly, significantly overcome out of plumb, displacement, the breakage defective that fractures, the advantage that pile quality significantly improves.
