Background technology
At present, along with expanding economy, building trade also develops rapidly thereupon, and in construction work, reinforcing bar is widely used as main body supporting structure.Often need bar connecting in practice of construction, increase the length of reinforcing bar, to adapt to the needs of different occasion.
Existing connecting method for reinforcing bars has a lot, and the most frequently used is straight thread formula mechanical splice, namely makes the steel sleeve that an inside is processed with straight thread, and two of required connection reinforcing bar heads are processed into outer straight thread, make itself and sleeve connection tighten respectively.This method not only can make steel area reduce when machining screw, weakens the supporting capacity of reinforcing bar, and the labour intensity of attended operation is large, inefficiency.
Utility model content
Technical problem to be solved in the utility model is to provide the reinforcing steel bar machinery joint that a kind of supporting capacity is strong, attended operation efficiency is high.
The technical solution of the utility model is as follows: a kind of reinforcing steel bar machinery joint, comprise sleeve and two, left and right reinforcing bar, it is characterized in that: the two ends, left and right of described sleeve all have conical bore, the aperture of described conical bore the inner is larger than the aperture of outer end, the termination of two reinforcing bars in described left and right is stretched in the conical bore at two ends, sleeve left and right separately, and the termination stretching into conical bore at described reinforcing bar has axial joint-cutting, in joint-cutting, accompany bibeveled voussoir, described reinforcing bar stretches into one end of conical bore and the hole wall tensioner of corresponding circle taper hole.
Adopt said structure, left and right reinforcing bar is connected with bibeveled voussoir by sleeve, and wherein voussoir is had the steel bar clamping of joint-cutting, and reinforcing bar stretches into the termination of conical bore by voussoir spreading simultaneously, makes reinforcing bar stretch into one end of conical bore and the hole wall tensioner of corresponding circle taper hole; Like this when left and right reinforcing bar is subject to outside pulling force, pulling force is larger, the pressure that sleeve is applied to reinforcing bar is larger, frictional force between reinforcing bar and sleeve is larger, steel bar end is made to be locked in sleeve securely, thus make being connected firmly between the reinforcing bar of the right and left, after connecting, the supporting capacity of reinforcing bar is strong.And when carrying out attended operation, only need the outer end little head end of voussoir being stuck in joint-cutting, reinforcing bar is stretched into corresponding conical bore, then by forcing press, pressure is applied to reinforcing bar, the corresponding termination of reinforcing bar is clamp-oned in conical bore further, the termination of voussoir spreading reinforcing bar simultaneously, the arc surface of steel bar end and the hole wall of conical bore are pushed against, and can complete connection quickly, attended operation is simple, labour intensity is low, considerably improves the operating efficiency of bar connecting.
Chamfering is had in the outer end of described joint-cutting.Offer chamfering to lead to voussoir, be convenient to voussoir and insert in joint-cutting.
As preferably, the apex angle α 1-3 ° less of the apex angle ss of voussoir of described conical bore.
Preferred as one, through by small sircle hole in the middle part of the conical bore of described sleeve the right and left, this sleeve casting.The intensity of sleeve is high, and production is easy, cost of production is low.
Preferred as another kind, through by small sircle hole in the middle part of the conical bore of described sleeve the right and left, the interior end of described conical bore, is connected with the stub end of corresponding voussoir, and voussoir just has semicircular indentations to the position of small sircle hole, described sleeve and voussoir integrally casting shaping.Small sircle hole on sleeve and the semicircular indentations on voussoir, the integrally casting being convenient to sleeve and voussoir is shaping.By sleeve and voussoir integrally casting shaping, not only the intensity of sleeve and voussoir high, produce easily, cost of production is low, and the management and of voussoir is all convenient.
Beneficial effect: the utility model is by opening conical bore at sleeve two ends, the termination of left and right reinforcing bar is stretched in conical bore, and open joint-cutting in this termination, voussoir is inserted in joint-cutting, reinforcing bar is made to stretch into one end and the conical bore hole wall tensioner of conical bore, thus provide a kind ofly to be connected firmly, supporting capacity is strong, attended operation efficiency is high reinforcing steel bar machinery joint, have be skillfully constructed, the feature such as structure is simple, processing ease.
