High tensile reinforcement refers to that tensile yield strength reaches 400MPa and above indented bars, has that intensity is high, the excellent feature of combination property, substitutes a large amount of 335MPa indented bars used at present with high tensile reinforcement, on average can saving steel more than 12%.Apply corresponding with high tensile reinforcement, the exploitation of high tensile reinforcement mechanical connecting joint technology becomes the hot issue that engineering circles is badly in need of solution.
At present, the most frequently used in engineering reinforced bar mechanical connector form has two kinds: cold extrusion sleeve pipe jointing and straight thread joint.Because the bearing capacity of high tensile reinforcement increases, to the requirement for bearing capacity also corresponding raising of sleeve pipe.Continue to adopt traditional cold extrusion sleeve pipe jointing, make it produce plastic strain by hydraulically operated fixture squeezing bushing, then have two kinds of possibilities: (1) if sleeve pipe adopts more low intensive steel, then casing size can be very large; (2) if sleeve pipe adopts high strength steel, cold extrusion produces the operating difficulties of plastic strain and easily there are quality problems after plastic strain.Adopt straight thread joint, then there is stripping rib, make the loaded down with trivial details operational sequence such as screw thread, and there is high tensile reinforcement cross section and weaken impaired situation, thus affect bearing capacity.
Utility model content
The purpose of this utility model is to provide a kind of cone wedge-type casing joint being applicable to high tensile reinforcement mechanical connection.
In order to solve the above problems, the utility model provides the cone wedge-type casing joint of a kind of high tensile reinforcement mechanical connection, comprise Ribbed Bar, cone wedge shape bushing pipe and steel sleeve, described cone wedge shape bushing pipe is provided with notch, Ribbed Bar is located in cone wedge shape bushing pipe, and described cone wedge shape bushing pipe is located in steel sleeve.
As further improvement of the utility model, described steel sleeve is arranged with horn mouth, described horn mouth inwall is provided with stairstepping pawl, and described cone wedge shape bushing pipe inwall and Ribbed Bar are fitted, described cone wedge shape bushing pipe outer wall and the horn mouth of steel sleeve and stairstepping pawl suitable.
As further improvement of the utility model, described cone wedge shape bushing pipe (2) adopts low-intensity steel to make.
As further improvement of the utility model, described steel sleeve (3) adopts high strength steel to make.
Implementation method of the present utility model comprises the following steps: step one: will bore wedge shape bushing pipe (2) and be enclosed within Ribbed Bar (1), and with special vice crush cones wedge shape bushing pipe (2), produce circumferential deformation, its notch (2-1) is diminished, and cone wedge shape bushing pipe (2) and Ribbed Bar (1) begin to take shape one.
Step 2: settle cone wedge shape bushing pipe (2) in the horn mouth (3-1) of steel sleeve (3) symmetrically, and cone wedge shape bushing pipe (2) is contacted with stairstepping pawl (3-2), carry out Primary Location.
Step 3: the end of symmetrical top cone-pressing wedge shape bushing pipe (2), make cone wedge shape bushing pipe (2) that enough accordion-like plastic strain occur, produce the double wedge matched with stairstepping pawl (3-2), simultaneously under the effect of extruding force, rib (1-1) in Ribbed Bar (1) embeds the inwall of cone wedge shape bushing pipe (2), by controlling the pressure on top surface of cone wedge shape bushing pipe (2) end, complete the enforcement of mechanical connection bar splice.
Compared with prior art, the utility model has the following advantages.
1. the high tensile reinforcement mechanical connecting joint that adopts of the utility model, sleeve pipe adopts high strength steel, and physical dimension is little, saves material.
2. joint of the present utility model is without the need to carrying out stripping rib, making the processing process such as screw thread to the termination of high tensile reinforcement, also produces plastic strain without the need to carrying out cold extrusion to steel sleeve, only needs to carry out axial compression to cone wedge shape bushing pipe, easy and simple to handle.
3. joint of the present utility model adopts the steel sleeve of high strength steel, in extruding construction, only elastic deformation occurs; The cone wedge shape bushing pipe generation accordion-like plastic strain of low-intensity steel, form double wedge, lock with the stairstepping pawl in steel sleeve, enough bond stresss and frictional force can be produced, and steel sleeve is uniform stressed circumferentially, make the mechanical connecting joint transmission force property of high tensile reinforcement excellent.
4., in the utility model, the double wedge that the stairstepping pawl on steel sleeve and cone wedge shape bushing pipe are formed, all has the feature that tooth root cross section is large, thus can bear larger axial push-pull stress.And under tension and compression effect, stairstepping pawl all can produce larger oblique compression power, make cone wedge shape bushing pipe tightly bond Ribbed Bar, make the connection status of mechanical connecting joint more tight, transmission force property is excellent.
