Abstract
The utility model discloses central screwing type construction line traction gripping apparatus, adopt central authorities in sleeve to extend out mode to be fixedly clamped construction line, namely by screwing in puller bolt, because puller bolt is with certain tapering, so along with screwing in going deep into of the outer expanding wall of central authorities, the opening position that central authorities extend out stress deformation gradually, makes the outer expanding wall of central authorities expand outwardly, thus is fastened by construction wire clamp by the clamping action of expanding wall outside the outer wall of sleeve and central authorities.In actual use, only need to screw in puller bolt and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.
Description
Technical field
The utility model relates to construction engineering technical field, more specifically, relates to central screwing type construction line traction gripping apparatus.
Background technology
In building operations, often need to carry out threading operation, namely in the duct various line for building or reinforcing bar (line of namely constructing) are connected, in construction, often adopt the external equipment such as hoist engine, strand pulling machine to carry out.Need to clamp in one end of various line to be connected or reinforcing bar, to make various line or reinforcing bar firmly be connected with external equipment, enough external force could be kept in whole threading process to draw.The construction line connected once disposable or number of steel bars more, will produce relative slip between each construction line or reinforcing bar, simple fastening structure very easily causes connection loosely, makes troubles to threading, such as broken string, slippage, upper power inconvenience etc. problem.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of central screwing type construction line traction gripping apparatus is provided, be intended to quickly and easily construction line to be compiled bundle clamping firmly, to realize efficient lashing smoothly, ensure whole bundle construction line in lashing process can all make in order, be not wound around each other.
Central authorities' screwing type construction line traction gripping apparatus, comprising: traction draw ring, puller bolt, sleeve, sleeve outer wall, the outer expanding wall of central authorities, puller bolt external screw thread, the outer expanding wall internal thread of central authorities, the outer expanding wall gap of central authorities.
One end of described sleeve is provided with traction draw ring, sleeve also comprises expanding wall outside sleeve outer wall and central authorities, outside described central authorities, expanding wall and sleeve outer wall are coaxially fixed, and expanding wall outside central authorities is arranged on the center of barrel bore, outside described central authorities, expanding wall entirety is cylindrical structure, its inner surface is provided with the outer expanding wall internal thread of central authorities, and the outer expanding wall of central authorities is also evenly provided with the outer expanding wall gap of central authorities, described puller bolt is provided with puller bolt external screw thread, and puller bolt is the taper bolt with certain taper, puller bolt extends out in wall construction by being threaded into central authorities, outside the puller bolt external screw thread of puller bolt and central authorities expanding wall inner surface central authorities outside expanding wall internal thread match.
In technique scheme, the quantity of described gap is 3 or 4.
In technique scheme, described gap is isosceles triangular structure, and its drift angle is 2--3 degree, and summit is 6--8 centimetre to the distance (i.e. the height of isosceles triangle) on base.
In technique scheme, outside the inner surface of described sleeve outer wall and central authorities expanding wall external surface between distance be 8--12 centimetre (specifically determining according to the diameter of line of constructing).
In technique scheme, the tapering of described puller bolt is 2--5 degree.
Compared with prior art, the technical solution of the utility model adopts central authorities in sleeve to extend out mode and clamps construction line, namely by screwing in puller bolt, because puller bolt is with certain tapering, so along with screwing in going deep into of the outer expanding wall of central authorities, the opening position that central authorities extend out stress deformation gradually, makes the outer expanding wall of central authorities expand outwardly, thus is fastened by construction wire clamp by the clamping action of expanding wall outside the outer wall of sleeve and central authorities.In actual use, only need to screw in puller bolt and can realize clamping connection easily and reliably, improve engineering construction efficiency, facilitate threading.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the sleeve used in the utility model;
Fig. 3 is the structural representation of expanding wall outside the central authorities that use in the utility model.
Wherein: 1 is traction draw ring, and 2 is puller bolt, and 3 is sleeve, and 4 is sleeve outer wall, and 5 is the outer expanding walls of central authorities, and 6 is puller bolt external screw thread, 7 is the outer expanding wall internal threads of central authorities, and 8 is the outer expanding wall gap of central authorities.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.
As shown in accompanying drawing 1-3, central screwing type construction line traction gripping apparatus, comprising: traction draw ring 1, puller bolt 2, sleeve 3, sleeve outer wall 4, the outer expanding wall 5 of central authorities, puller bolt external screw thread 6, the outer expanding wall internal thread 7 of central authorities, the outer expanding wall gap 8 of central authorities.
Wherein:
One end of described sleeve 3 is provided with traction draw ring 1, sleeve 3 also comprises expanding wall 5 outside sleeve outer wall 4 and central authorities, outside described central authorities, expanding wall 5 and sleeve outer wall 4 are coaxially fixed, and expanding wall outside central authorities 5 is arranged on the center of sleeve 3 inner chamber, outside described central authorities, expanding wall 5 entirety is cylindrical structure, its inner surface is provided with the outer expanding wall internal thread 7 of central authorities, and the outer expanding wall 5 of central authorities is also evenly provided with the outer expanding wall gap 8 of central authorities, described puller bolt 2 is provided with puller bolt external screw thread 6, and puller bolt 2 is the taper bolt with certain taper, puller bolt 2 is by being threaded in outer expanding wall 5 structure of central authorities, outside the puller bolt external screw thread 6 of puller bolt 2 and central authorities expanding wall 5 inner surface central authorities outside expanding wall internal thread 7 match.
In technique scheme, the quantity of described gap is 3 or 4.
In technique scheme, described gap is isosceles triangular structure, and its drift angle is 2--3 degree, and summit is 6--8 centimetre to the distance (i.e. the height of isosceles triangle) on base.
In technique scheme, outside the inner surface of described sleeve outer wall and central authorities expanding wall external surface between distance be 8--12 centimetre (specifically determining according to the diameter of line of constructing).
