Abstract
The invention discloses a bar connection structure, which comprises the following parts: bar end, a couple of semi-circular connecting jacket and a couple of hoop, wherein the outer face of bar end and inner surface of connecting jacket contain the corresponding gauffer; the external jacket concludes two hoops. The bar end manufacturing method comprises the following steps: reinforcing the bar connecting end axis vertically in the atmospheric temperature; pressing the external surface of bar connecting end as a group of convex groove and projecting rib for connecting. The structure design is longer external diameter in the middle of connecting jacket, which displays fastening effect through the hoop moving toward center in the connecting course. Any part of bar can be connected conveniently and rapidly and the precision of convex groove and projecting rib is high, which can match the gauffer of connecting jacket to accomplish the satisfactory effect.
Description
Technical field
The present invention relates in the construction work end reinforced processing method in a kind of steel bar connecting structure (device) and this syndeton.
Background technology
In the modern architecture, reinforcing bar connects speed of application and joint quality has very big influence to programming and workmanship, therefore is regarded as a key link of structure design and construction always.At present, the connecting method for reinforcing bars that adopts in the concrete building structures mainly contains colligation connection, welding both at home and abroad, and various mechanical connection methods, wherein, the taper thread with the mechanical connection method connects, the sleeve extruding connects, jumping-up is threaded, roll extrusion straight thread connection etc. used more general.But these methods all exist deficiency: taper thread connects, and the intensity of joint does not reach parent material of reinforcement rebar intensity, and the application in structure is restricted; Cover letter extruding connects, and the sleeve steel using amount is big, and cost is higher, and equipment is heavy when station is constructed, and connection speed is slower; Jumping-up connects, and makes steel bar joint screw and needs jumping-up, cutting thread twice manufacturing procedure, and operation and qualifying point are more; The roll extrusion straight thread connects, and with the technology of rolling and processing screw thread again behind the stripping rib, a screw thread steel silk machining period is longer usually, and the number of turns of rotational sleeve is also more when connecting, and the winding operation in the intensive reinforcing bar is pretty troublesome.In addition, once the someone had proposed a kind of " Ribbed Bar kink jointing " (Chinese patent ZL97215872.3), it is quick and convenient when this joint connects, but need the cross rib of reinforcing bar appearance and the helicla flute in its adapter sleeve well to coincide and to use, and concerning reinforcing bar, the cross rib of reinforcing bar appearance itself is not to design and process for connecting reinforcement, so the product differentiation of different manufacturers is very big, even the mould of the different steel rolling muscle of same producer also has than big-difference, the manufacturer of adapter sleeve can not design by the rolling mould of corresponding reinforcing bar correspondingly, produce adapter sleeve, so this joint can't be applied so far.
Summary of the invention
Purpose of the present invention just provides end reinforced processing method in a kind of steel bar connecting structure and this syndeton, solves construction inconvenience and inefficient problem that prior art exists.Satisfy architectural design, unit in charge of construction better to reinforcing bar connection speed and performance demands.
Technical scheme of the present invention is:
A kind of steel bar connecting structure, comprise the end of a pair of reinforcing bar that will dock, a pair of semicircle chuck and two hoops of connecting, a pair of connection chuck to be buckled in a pair of end reinforced outside, two hoops are enclosed within and connect outside the chuck, be equipped with the asperities of coincideing mutually in the described end reinforced outside and the inboard that is connected chuck, and be meshing with each other together; The middle part diameter in the outside of described connection chuck is greater than the diameter at two ends; The internal diameter of described hoop is slightly larger than the external diameter that connects the chuck two ends, and two hoops make two connection chucks draw close and be close to reinforcing bar when the joint middle part advances.
End reinforced processing method in the described steel bar connecting structure of a kind of claim 1, at normal temperatures with processed end reinforced placing in the moulding form, the inboard of this mould be provided with described connection chuck in identical groove and the fin of asperities, use then hydraulic test perpendicular to end reinforced axis to the mould reinforcing, suppress one group of described asperities by mould at reinforcing bar link external surface, this group asperities is used for and the described asperities engagement that is connected in the chuck, transmits suffered pulling force when the reinforcing bar tension.
Because of we's non-machining owned by France, similar to the rolled thread principle, reinforcing bar connection asperities is made in cold working, can not reduce the bonding strength of reinforcing bar linkage section, and the groove and the fin precision height of processing, can be good fit with the asperities that is connected chuck, reach good connection effect.
Advantage of the present invention: 1, the processing method of this reinforcing bar link is simple, quick, is better than existing screw thread steel processing method; 2, reinforcing bar applied widely, that the appearance and size deviation is big, reinforcing bar with ribbing, not with ribbing can both process the asperities that satisfies the switching performance requirement with this method; 3, be embedded in steel bars in concrete, also can have gone up asperities, and realize connecting with this syndeton with this method processing; 4, winding is very convenient at the scene for this syndeton, and the reinforcing bar at any position of structure can both be finished connection apace with this syndeton; 5, the bonding strength of this syndeton surpasses parent material of reinforcement rebar, and quality of connection is reliable; 6, this syndeton volume is little, and production technology is simple, and cost is low, is better than existing reinforcing steel bar machinery method of attachment;
Below in conjunction with accompanying drawing syndeton of the present invention and processing method are described further.
