Description
Technical field
The present invention relates to a kind of precast concrete pile mechanical connection pile crown, particularly relate to mechanical connection pile crown and the manufacture method thereof of a kind of end plate recycling precast concrete pile.
Background technology
The pile tube of existing centrifugal forming, hollow square pile, after pile foundation construction, the main method that pile crown is connected with cushion cap is: scene is cleared up, chisel out the laitance layer of an endoporus, a pallet is suspended in midair at stake endoporus, the reinforcing cage that colligation is good inserts endoporus, building slightly expanded concrete to endoporus again makes endoporus fill out core completely, this construction technology is complicated, cycle is long, costly, quality control difficulty is large, it is also often not enough that endoporus fills out core bonding frictional force, especially high in groundwater table, when storm drain not in time etc. causes basement buoyancy large, endoporus institute wadding weft variation is easily separated with pile body, thus also easily there is basement floating-up, the quality accident of tilting, and the method that solid square pile pile crown is connected with cushion cap mainly: adopt broken pile crown, pull down end plate, expose reinforcing bar, curved for reinforcing bar anchor is anchored into cushion cap concreting together with cushion cap reinforcing bar binding, impact is had to cause damage to the concrete of pile crown, pile body when the shortcoming of this connected mode is broken pile crown, difficulty of construction is large, and efficiency is also very low.Pile for prestressed pipe, the offcenter squared pile of current national standard specification have end plate, but the non-dismountable recovery of pile crown end plate, and when being connected with foundation platform, pile crown end plate all anchors into cushion cap, wastes steel resources.And solid square pile end plate and reinforcing bar directly weld, impact pile crown during dismounting, and dismantle with gas cutting, end plate is easily out of shape can only regard scrap iron process.
Summary of the invention
Object of the present invention is just the mechanical connection pile crown and the manufacture method thereof that provide a kind of end plate recycling precast concrete pile in order to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of mechanical connection pile crown of end plate recycling precast concrete pile, comprise end plate, branch sleeve, reinforcing bar and pre-embedded bolt, described reinforcing bar is connected with described branch sleeve, described end plate is connected by high-strength set bolt with described branch sleeve, described end plate is provided with multiple high-strength fixed bolt hole, three pre-embedded bolt holes and three plate screwed holes, described pre-embedded bolt hole and described plate screwed hole are distributed on the concentric circles center line of end plate, described pre-embedded bolt is installed in the pre-embedded bolt hole on described end plate and with two nuts, described end plate is locked, described reinforcing bar is that head is processed into the prestressed reinforcement of Upsetting head shapes or the indented bars after being processed into screw thread, described pre-embedded bolt is common double hook bolt or screw.
If produce the preformed pile of prestressed concrete centrifugal forming, on, spraying one deck interleaving agent in lower punching block, put on branch sleeve after Steel Reinforcing Bar Material and be processed into Upsetting head at reinforcing bar head again, then reinforcing cage is worked out, reinforcing cage is put into counterdie, utilize stretch board, anchor plate and high-strength set bolt will install the end plate of pre-embedded bolt, branch sleeve is together with assembling steel reinforcement cage, then by the even feeding of concrete for preparing in counterdie, close upper punching block again, with wind big gun locking mold closing screw, carry out prestressed stretch-draw again, centrifugal forming is carried out after stretch-draw, curing pool maintenance is inserted after centrifugal forming, preformed pile carries out the demoulding after reaching demoulding strength, remove the high-strength set bolt of stretch-draw anchor, change fixed charge method end plate high-strength set bolt and at end plate counterbore internal locking.C80 preformed pile in this way, also needs through autoclave steam pressure, reaches to go out still after C80 intensity and be deposited into that final product storage is quiet stops natural curing until concrete, in high-strength fixed bolt hole and pre-embedded bolt hole, rises on plate screwed hole and embeds vinyl cover, deliver to building site piling after 3 days.If solid square pile, when reinforcing bar is prestressed reinforcement, put on branch sleeve after Steel Reinforcing Bar Material and be processed into Upsetting head at reinforcing bar head again, then reinforcing cage is worked out, reinforcing cage is put into the punching block having sprayed interleaving agent, utilize stretch board, anchor plate and high-strength set bolt by installing the end plate of pre-embedded bolt, branch sleeve together with assembling steel reinforcement cage, then carries out prestressed stretch-draw, if nonprestressed reinforcement (screw-thread steel), screw thread is processed at the head of screw-thread steel, then reinforcing cage is worked out, reinforcing cage is put into the punching block having sprayed interleaving agent, before and after utilizing, anchor plate and high-strength set bolt will install the end plate of pre-embedded bolt, branch sleeve is together with assembling steel reinforcement cage, then by the even feeding of concrete for preparing in punching block, employing vibrate or self-compaction shaping, the demoulding after demoulding strength is reached after natural curing or outer heating and moistening maintenance, remove the high-strength set bolt of anchoring, change fixed charge method end plate high-strength set bolt and at end plate counterbore internal locking, in high-strength fixed bolt hole and pre-embedded bolt hole, rise on plate screwed hole and embed vinyl cover, then proceed to that final product storage is quiet stops natural curing.After concrete precast pile piling, remove the nut of high-strength set bolt, pre-embedded bolt in counter sink on end plate, then crab bolt will be played screwed in plate screwed hole, by end plate jack-up, recyclable recycling that end plate is intact.
Particularly, described end plate is divided into hexagon socket head cap screw nose end plate and interior hexagonal flower pattern sunk screw end plate according to the different of the connected mode from described branch sleeve.
Particularly, described hexagon socket head cap screw nose end buttress is divided into the boss end plate of band punching press boss and the platform end plate not with punching press boss according to structure difference, and the inner plane side of described boss end plate is provided with cylindrical boss along the position of described high-strength fixed bolt hole.
Particularly, described branch sleeve is divided into prestressing force sleeve and non-prestressed sleeve, described prestressing force sleeve is connected with described end plate and described high-strength set bolt by PC rod iron, and described non-prestressed sleeve is connected by described high-strength set bolt with described end plate by screw-thread steel.
