According to the steel bar joint fastener, steel bars can be conveniently and rapidly in butt joint with steel bars in the prestressed concrete member. The steel bar joint fastener consists of a steel bar coupling nut and an annular clamping piece, wherein an annular clamping piece clamping hole is formed in the bottom of the steel bar coupling nut; the annular clamping piece is arranged in the annular clamping piece clamping hole; an annular clamping table is arranged at the upper end of the annular clamping piece clamping hole; a screw thread is formed in the inner wall of the steel bar coupling nut. The steel bar joint fastener has the advantages that 1, the defects existing in the background technology are overcome, the butt-joint speed is high, and the reliability is high; 2, a stress signal between the butt-jointed steel bars is high in transfer strength and is conveniently detected; 3, an upset head between the steel bars is absent, so that the strength of the steel bars is ensured, the raw material consumption is reduced, and the energy consumption is avoided.
Description
Technical field
The utility model relates to a kind of prestressed concrete member reinforcing bar that can easily reinforcing bar be implemented to rapid abutting joint with the reinforcing bar in concrete precast element and connects button, belongs to prefabricated component steel reinforcement abutting joints fastener and manufactures field.
Background technology
CN1740456A, title " top pile extension and prefabricated component under upper spiral shell ", fastener is female thread structure or is external thread structure or is interior interface arrangment or is outer interface arrangment, the fastener Qiang Di center of female thread structure, external thread structure, interior interface arrangment, outer interface arrangment has reinforced hole, the periphery of reinforced hole one end is reinforcing bar end upset Ka Tai, and the heading of reinforcing bar is connected on Ka Tai.On this background technology is fundamentally eliminated, lower pile crown plate, guaranteed that the steel hoop on pile tube skeleton not only can be around to pile tube skeleton two ends, and can guarantee that its point is welded on the longitudinal reinforcement of skeleton, guarantee the uniformity of pile tube intensity, fundamentally avoid the fracture of pile tube with broken, solve some longitudinal reinforcements in pile tube and longitudinally haled extension uniformity, guarantee the uniformity of industrialized mass production pile tube inherent quality, but be subject to the impact of bar diameter error, exist reinforcing bar and stretch-draw nut or top to draw nut contact area little, a little less than stress signal transmits, be not easy to detect, secondly, because reinforcing bar end upset is large, during making, not only need reinforcing bar heating high-temperature process, cause the intensity of reinforcing bar end upset and reinforcing bar end upset joint portion reinforcing bar to decline, affect reinforced steel bar strength, and waste of raw materials greatly, consume energy high, particularly antiseptic property improves, because of the antiseptic property of steel and iron parts after being heated, to reduce all too large, existing without heading just, without being hurt, that just needn't preservative treatment.
Current existing concrete tubular pile is after completing piling, and the reinforcing bar on its concrete tubular pile basseting need to extend docking during reinforcing bar, can only adopt the mode of wire binding to carry out or adopt electric welding.Its weak point: wire binding intensity is low, poor reliability; And electric welding is not only time-consuming, and in operation inconvenience.
utility model content
[0004]purpose of design: avoid the weak point of background technology, design a kind of prestressed concrete member reinforcing bar that can easily reinforcing bar be implemented to rapid abutting joint with the reinforcing bar in concrete precast element and connect button.
Design scheme: in order to realize above-mentioned purpose of design.At the bottom of reinforcing bar coupling nut cap, have annular card blocked hole, annular card is positioned at the design of annular card blocked hole, is one of technical characterictic of the present utility model.The object of doing is like this: because the annular card blocked hole diameter at the bottom of cap in reinforcing bar coupling nut is upper large, descend little and mate with the annular card of conical external circle face, when annular card anchor ear is on reinforcing bar, what its annular card periphery formed with annular card blocked hole at the bottom of cap in reinforcing bar coupling nut is that face interference clamping coordinates, when reinforced bar stretching, its reinforcing bar and annular card, annular card blocked hole in annular card and reinforcing bar coupling nut at the bottom of cap forms powerful combination with pressure, both guaranteed reliable contact the between reinforcing bar and annular card, guaranteed again reliable contact the between reinforcing bar and annular card, not only stress transmission of signal intensity is good, and be convenient to detect.2, reinforcing bar upper end, without the design of heading, is two of technical characterictic of the present utility model.The object of doing is like this: because reinforcing bar of the present utility model upper end is without heading, therefore in processing, both reduced the consumption of reinforcing bar material, and reinforcing bar loss had been reduced and reach 100%, and guaranteed again the impact of high temperature heading processed on reinforced steel bar strength, and avoided energy consumption consumption.3, annular card and reinforcing bar card access surface are provided with the design of boss, are three of technical characterictics of the present utility model.The object of doing is like this: because the boss of annular card card access surface is arc boss and forms clamping with groove on reinforcing bar (screw-thread steel) and coordinates, so anti-sticking reinforcing bar is deviate from from annular card effectively.
Technical scheme: a kind of prestressed concrete member reinforcing bar is haled fastener, reinforcing bar coupling nut bottom endoporus is up big and down small conical wall, annular card external diameter is up big and down small taper, interior tooth or the tongue and groove being consistent with reinforcing bar is set in the other direction, makes the concavo-convex muscle shape of reinforcing bar firmly be clipped in card, be subject to nut that reinforcing bar connects spiral shell inwall to carry out stretch-draw with haling after screw thread that bolt is consistent docks, after making product, be connected with the bolt thread of external reinforcing bar, reach the seamless link of prefabricated component and external steel reinforcement abutting joints and any cast-in-place concrete structure.
The utility model is compared with background technology, and the one, the weak point of having avoided background technology to exist, docking speed is fast, reliability is high; The 2nd, between the reinforcing bar after docking, stress signal transfer strength is high, is convenient to detect; Three because reinforcing bar is without heading, has both guaranteed reinforcing bar reinforced steel bar strength, has reduced raw materials consumption not only but also avoided energy consumption consumption.
