Abstract
The invention relates to a process for connecting reinforcement for prestressed pipe piles. The process comprises the following steps: (1) polishing the upper end faces of the prestressed pipe piles into radial planes and keeping prestressed reinforcement and the upper planes parallel; (2) manufacturing ring holes for installing clamp wires on the prestressed reinforcement, wherein the ring holes are coaxial with the prestressed reinforcement; (3) coaxially clamping the clamp wires at the ends of the prestressed reinforcement and locking and fixing the clamp wires; and (4) radially installing a pile tip end plate on the clamp wires by ensuring the upper parts of the clamp wires to protrude out of through holes manufactured on the pile tip end plate and then fixing the clamp wires on the pile tip end plate by adopting locknuts. According to the process, the clamp wires are adopted to lift the reinforcement of the prestressed pipe piles onto the pile tip end plate respectively and are in the form of two-section three-claw screw threads to connect and lift the reinforcement, and the connection is firm and reliable, thus the prestress of the reinforcement after the piles are cut off is continued, the strength of the prestressed pipe piles is maintained and the building quality is ensured.
Description
Technical field
The invention belongs to building field, relate to pile for prestressed pipe, especially a kind of pile for prestressed pipe connects the muscle process.
Background technology
Pile for prestressed pipe is the stake for building of directly being driven underground, and owing to underground ground geological condition complexity, therefore, the pile tube of equal length can not be realized the identical degree of depth, for the pile tube that can't go deep into, adopts a section stake mode to realize flushing of stake for building usually.But owing to be pile for prestressed pipe, the consequence of therefore cutting stake is the prestressing force that has destroyed reinforcing bar, and section stake of pile for prestressed pipe generally is difficult to connect muscle and keeps prestressing force, causes pile tube can't reach designing requirement.At present, still there is not the solution to the problems described above of discovery.
By retrieval, do not find the publication document identical with present patent application yet.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and after cutting stake, also can keep the prestressed, reinforced pile for prestressed pipe of pile tube to connect the muscle process.
The object of the present invention is achieved like this:
A kind of pile for prestressed pipe connects the muscle process, and step is:
(1) sagittal plane is worn in the upper surface of pile for prestressed pipe, prestressed reinforcement and last plane keeping parallelism;
(2) at the prestressed reinforcement position and with coaxial the making of prestressed reinforcement the annular distance that blocks silk is installed;
(3) will block the coaxial end that snaps fits into prestressed reinforcement of silk, and locking, fixing;
(4) on the card silk pile crown end plate is installed radially, card silk top leans out the made through hole of pile crown end plate, adopts locknut will block silk then and is fixed on the pile crown end plate.
And, described will block silk and be fixed on the pile crown end plate after, again at pile tube upper end coaxial package one pile protection hoop, this pile protection hoop adopts opening pile protection hoop, the opening at opening pile protection hoop adopts trip bolt to carry out fastening then; This position, pile protection hoop upper edge and the welding of pile crown end plate are fixing, and pile protection hoop upper edge is flushed with plane on the pile crown end plate.
And, the degree of depth 5-7cm of annular distance in the described step (2), diameter 4-6cm.
And, described card silk is made of swivel nut, locknut, taper silk braid and three-jaw screw thread, at swivel nut top engagement suit locknut, the taper silk braid is installed in coaxial engagement in swivel nut, this taper silk braid upper surface middle part is shaped on a cubic blind hole, the bottom of taper silk braid is shaped on bellmouth, radially uniform setting-in three-jaw screw thread in this bellmouth.
And, also being shaped on reverse taper hole in the swivel nut below corresponding three-jaw screw thread, the lower surface of corresponding three-jaw screw thread also is equipped with the screw thread of falling the three-jaw in this reverse taper hole, by the axial displacement of taper silk braid, the synchronous radial expansion of three-jaw screw thread and the screw thread of falling the three-jaw.
And, be shaped on radially upright groove in the swivel nut upper end.
Advantage of the present invention and good effect are:
1, the present invention adopts the card silk that the reinforcing bar of pile for prestressed pipe is lifted respectively on the pile crown end plate, the card silk is to adopt two sections three-jaw screw threads that reinforcing bar is connected to lift firm and reliable connection, the prestressing force of reinforcing bar after section stake that continued, the intensity that has kept pile for prestressed pipe has guaranteed the quality of building.
2, card silk of the present invention is to utilize manual engagement system to realize the radial expansion of two sections three-jaw screw threads, and adopt the taper silk braid to carry out the axial displacement of two sections three-jaw screw threads to realize automatic radial expansion, avoided the disturbance of reinforcing bar, guaranteed the supporting capacity of pile for prestressed pipe, simple in structure, design science, with low cost, result of use is good.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described; Need to prove: present embodiment is descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of pile for prestressed pipe connects the muscle process, and step is:
(1) sagittal plane is worn in the upper surface of pile for prestressed pipe 4, prestressed reinforcement 6 and last plane keeping parallelism;
(2) at the prestressed reinforcement position and with the coaxial annular distance 5 of making of prestressed reinforcement, this annular distance degree of depth 5-7cm, diameter 4-6cm;
(3) will block the silk 3 coaxial ends that snap fits into prestressed reinforcement, and locking, fixing;
(4) on the card silk pile crown end plate 2 is installed radially, card silk top leans out the made through hole of pile crown end plate, adopts locknut will block silk then and is fixed on the pile crown end plate;
(5) at pile tube upper end coaxial package one pile protection hoop 1, can adopt opening pile protection hoop, the opening at opening pile protection hoop adopts trip bolt to carry out fastening then; This position, pile protection hoop upper edge and the welding of pile crown end plate are fixing, and pile protection hoop upper edge is flushed with plane on the pile crown end plate.
The effect that installs the pile protection hoop is an intensity of strengthening prestressed pipe pile head position.
The present invention is made of swivel nut 10, locknut 9, taper silk braid 12 and three-jaw screw thread 13 at the card silk described in the step (3), be shaped on radially upright groove 8 in the swivel nut upper end, at swivel nut top engagement suit locknut, this locknut lockable Ben Kasi and pile crown end plate, and adopt the iron chi to be inlaid on the column 7 between the radially upright groove when locknut locks, to position; The taper silk braid is installed in coaxial engagement in swivel nut, and this taper silk braid upper surface middle part is shaped on a cubic blind hole 11, and this four directions blind hole can adopt cubic spanner to carry out the axial displacement of taper silk braid in swivel nut; The bottom of taper silk braid is shaped on bellmouth, radially uniform setting-in three-jaw screw thread in this bellmouth; Also be shaped on reverse taper hole in the swivel nut below corresponding three-jaw screw thread, the lower surface of corresponding three-jaw screw thread also is equipped with the screw thread of falling the three-jaw 14 in this reverse taper hole; By the axial displacement of taper silk braid, can realize the synchronous radial expansion of three-jaw screw thread and the screw thread of falling the three-jaw.
The present invention is suitable for the stake of circle stake, side's stake and other shapes equally.
