Description
Technical field
The present invention relates to a kind of steel bar anchoring device and anchoring process, particularly a kind of tapered sleeve without the need to arranging end reinforced screw thread locks steel bar anchoring device and anchoring process, belongs to steel concrete anchoring technical field.
Background technology
" reinforcing steel bar machinery anchoring " has the applicating history of decades in west economy developed country, start at nearly 10 years in the application of China.
To those skilled in the art, traditional is substantially all adopt " bent bar anchorage " for the Bar Anchorage in steel concrete, and disadvantage is waste reinforcing bar, and anchorage node place reinforcing bar is intensive, not easily ensure the quality of concreting, the curved muscle processing of reinforcing bar is made troubles.
And along with the progress of technology, mostly the reinforcing steel bar machinery anchor plate of current domestic use is straight thread and welding connecting mode, its Bar Anchorage plate adopts the female circular anchor plate of band and screwed reinforcing bar to combine, as illustrated in fig. 1 and 2.But this connected mode need when applying in engineering to process in advance prefabricated, time-consuming, take a lot of work, it has following shortcoming: 1) must to carry out processing in advance prefabricated for reinforcing bar, adds prefabricated process links and prefabricated cost; 2) the screw thread silk head after processing also answers safekeeping, just cannot connect once cause damage, install: 3) screw thread anchor plate needs all will ensure its quality requirement in processing and installation two links, and the anchor plate that this patent relates to only has a fixing link to be Quality Control Links; 4) thread parameter inconsistent (when the supplier of anchor plate and joint is not) of the bar splice providing the specification of the producer's screw thread steel that it requires processing, size and job site to use of general anchor plate, the independent separate machined of screw thread silk head is cumbersome, also not manageability, once silk head loads in mixture very easily will cause quality accident, so when causing project anchor plate negligible amounts, the situation of supplier's supply of being unwilling of anchor plate, but design has explicitly called for again use mechanical anchor plate.
Therefore, when current domestic cost of labor significantly improves, the mode be threaded is more and more inconvenient, and integrated cost is high, is not easy to the application in engineering.
Summary of the invention
The present invention is in order to overcome above-mentioned defect, propose a kind of tapered sleeve without the need to arranging screw thread steel silk head and lock steel bar anchoring device and anchoring process, it eliminates the prefabricated link of screw thread steel processing, effectively solves reinforcing bar and fast installs and the technical problem of quality control.
Technical scheme of the present invention is as follows:
A kind of tapered sleeve locking steel bar anchoring device, described tapered sleeve locking steel bar anchoring device comprises the tapered sleeve anchor plate outside intermediate plate and intermediate plate; Described intermediate plate is multi-disc, and it has cogged inner surface and single conical surface external surface, and intermediate plate described in multi-disc will treat that the reinforcing bar of anchoring wraps up, is engaged by cogged inner surface; Described tapered sleeve anchor plate is head shoulder disjunctor shape, its center is provided with the conical bore axially arranged, described intermediate plate and treat that anchor bar is set in the described conical bore inside center of tapered sleeve anchor plate successively, locks the reinforcing bar treating anchoring wrapped up in intermediate plate and intermediate plate simultaneously by tapered sleeve anchor plate; The tapering of described conical bore is identical with intermediate plate tapering, and conical bore diameter by inner side shoulder laterally head reduce gradually; Described intermediate plate cogged inner surface has spaced multiple stepped tooth; Described intermediate plate and tapered sleeve anchor plate all adopt alloy steel material manufacture; Describedly treat the end reinforced without the need to processing anchoring screw thread of anchoring.
Further, described tapered sleeve anchor plate shape of cross section is circular, square, oval or polygon.
Further, described intermediate plate be two panels, three or four.
Further, intermediate plate described in multi-disc is symmetricly set on and treats anchor bar surrounding.
Further, described intermediate plate outboard end flushes with when anchor bar outboard end is placed or does not flush.
Further, described head shoulder disjunctor shape tapered sleeve anchor plate is replaced with the cylinder of equal thickness, square body or polygon cylinder.
Further, described intermediate plate cogged inner surface is arc-shaped, in order to treat that the external surface of anchor bar is tightly fitted and is engaged.
Further, described intermediate plate has certain intensity and hardness and toughness, to ensure intermediate plate flexural deformation in clamping process, is unlikely to fracture; And described intermediate plate list conical surface external surface and tapered sleeve anchor plate conical bore inner surface are smooth treatment surface; Described intermediate plate and tapered sleeve anchor plate all adopt the alloy steel material manufacture containing Cr.
Further, treat described in that anchor bar is Ribbed Bar, plain bar or rod iron.
The anchoring process of above-mentioned tapered sleeve locking steel bar anchoring device, comprises the steps:
Step one: make corresponding intermediate plate and tapered sleeve anchor plate;
Step 2: make it circumferentially be uniformly distributed by a plastic cage intermediate plate described in multi-disc and be formed as an entirety, and loaded and treat the end reinforced of anchoring, and the larger one end of intermediate plate thickness is placed towards inboard, the less one end of thickness then towards arranged outside, and makes outboard end flush with when anchor bar outer end is placed;
Step 3: the conical bore of tapered sleeve anchor plate is corresponding consistent with the intermediate plate conical surface in step 2, by tapered sleeve anchor plate from treating that anchor bar end is stretched into and is enclosed within intermediate plate external surface;
Step 4: adopt clamping tool by tapered sleeve anchor plate and intermediate plate axial compression, the so far anchor device installation of reinforcing bar.
Wherein, the profile of tooth crown in the present invention can not excessively flat (than standard tooth form point), otherwise clamping reinforcing bar needs larger power, also easily damages reinforcing bar; But profile of tooth again can not be excessively sharp, otherwise the intensity of tooth can not meet the demands.Therefore, present invention employs stepped tooth shape, its one end towards the reinforcing bar comparatively other end is thin, and in order to improve snap-in force, and stepped tooth spacing designs according to standard pitch.
Beneficial effect:
1, the prefabricated link eliminating screw thread steel processing installed by anchor device of the present invention, saves worked structure and the processing cost of prefabricated link;
2, quick for installation, convenient, reliable, quality is easy to control;
3, with the processing of on-the-spot steel concrete supporting, prefabricated without any relation, the cross-cutting issue of quality managemant can not be caused, even if quantity does not affect the application of its product less yet.
