Abstract
The invention discloses a portable traction and reinforcing device for construction wires. The portable traction and reinforcing device is characterized in that one end of a sleeve is sealed and fixedly provided with a pull ring at the center, the other end of the sleeve is open and coaxially fixedly provided with a central clamping column, and a second thread is arranged on the outer side of the wall of the sleeve; a tightening part is arranged on the outer side of the sleeve wall at the sealed end of the sleeve, a first thread is arranged on the inner side of the tightening part, and the first thread is matched with the second thread; the thickness of the wall of the sleeve gradually increases from the sealed end of the sleeve to the open end of the sleeve, and notches are evenly formed in the sleeve wall at the open end of the sleeve along the circumferential direction of the sleeve wall. The portable traction and reinforcing device has the advantages that clamping is performed from the outer side of the sleeve, connection can be achieved conveniently and reliably by tightening the tightening part during actual use, project construction efficiency is increased, and threading is facilitated.
Description
Technical field
The present invention relates to construction engineering technical field, more specifically, relate to portable construction line traction bracing means.
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.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide portable construction line to draw bracing means, be intended to quickly and easily construction line to be compiled and restraint, and can convenient connection and running through.
Technical purpose of the present invention is achieved by following technical proposals:
Portable construction line traction bracing means, comprises draw ring, cylindrical shell and screw parts, wherein:
One end of described cylindrical shell is closed and is fixedly installed draw ring in middle position, and the other end opening of described cylindrical shell is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, described first screw thread and the second screw thread match;
From cylindrical shell blind end to cartridge openings end, described barrel inner surface surrounds the cylindrical lumens of equal diameter, and the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.
In technique scheme, the quantity of described gap is 3 or 4.
In technique scheme, the drift angle of described gap is 10-15 degree.
In technique scheme, described in screw parts be hex nut.
Compared with prior art, technical scheme of the present invention adopts clamping mode outside sleeve, utilization screws parts and implements to screw along barrel, space between barrel and central clamping column is reduced gradually, to realize the fixing of line of constructing in sleeve, namely by screwing parts, container wall inwardly shrinks, owing to arranging gap at the barrel of cartridge openings end, the barrel receiving extruding will radially inwardly shrink, clamp the construction line be arranged between barrel and central clamping column, to realize the fixing of connection.In actual use, only need to screw parts and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.

Fig. 1 is structural representation of the present invention (1);
Fig. 2 is structural representation of the present invention (2);
Fig. 3 is structural representation of the present invention (3).
Wherein 1 is draw ring, and 2 is cylindrical shell, and 3 is the first screw thread, and 4 for screwing parts, and 5 is barrel, and 6 is the second screw thread, and 7 is central clamping column, and 8 is gap.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with specific embodiment.
Three figure as shown in accompanying drawing 1-3 are respectively sectional view of the present invention, lateral view and elevation, and the present invention's portable construction line traction bracing means, comprises draw ring, cylindrical shell and screw parts, wherein:
One end of described cylindrical shell is closed and is fixedly installed draw ring in middle position, and the other end opening of described cylindrical shell is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, described first screw thread and the second screw thread match;
From cylindrical shell blind end to cartridge openings end, described barrel inner surface surrounds the cylindrical lumens of equal diameter, and the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.
In technique scheme, the quantity of described gap is 3 or 4, is shown as four in figure.
In technique scheme, the drift angle of described gap is 10-15 degree.
In technique scheme, described in screw parts be hex nut.
Compared with prior art, technical scheme of the present invention adopts clamping mode outside sleeve, utilization screws parts and implements to screw along barrel, space between barrel and central clamping column is reduced gradually, to realize the fixing of line of constructing in sleeve, namely by screwing parts, container wall inwardly shrinks, owing to arranging gap at the barrel of cartridge openings end, the barrel receiving extruding will radially inwardly shrink, clamp the construction line be arranged between barrel and central clamping column, to realize the fixing of connection.In actual use, only need to screw parts and can realize easily and reliably connecting, improve engineering construction efficiency, facilitate threading.
Above to invention has been exemplary description; should be noted that; when not departing from core of the present invention, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection scope of the present invention.
Claims (4)
1. portable construction line traction bracing means, it is characterized in that, comprise draw ring, cylindrical shell and screw parts, wherein: one end of described cylindrical shell is closed and is fixedly installed draw ring in middle position, the other end opening of described cylindrical shell is also fixedly installed central clamping column at central coaxial, at barrel arranged outside second screw thread; The barrel arranged outside closing one end at cylindrical shell screws parts, described in screw parts inner side the first screw thread is set, described first screw thread and the second screw thread match; From cylindrical shell blind end to cartridge openings end, described barrel inner surface surrounds the cylindrical lumens of equal diameter, and the thickness of barrel increases gradually, and on the barrel of cartridge openings end, evenly arranges gap along barrel circumferencial direction.
