Abstract
The utility model discloses a rigging threaded sleeve device for abutting connection of reinforcing steel bars, comprising a middle connecting part, wherein one end of the middle connecting part is fixedly connected with a plus-thread connector, while the other end thereof is fixedly connected with a minus-thread connector; and the cross section of the middle connecting part is rectangular. The rigging threaded sleeve device for abutting connection of reinforcing steel bars avoids the operation of binding and abutting the reinforcing steel bars aloft, and is capable of binding the reinforcing steel bars into a standard steel reinforcement cage on the ground and then abutting and mounting the same aloft; therefore, the personal safety is guaranteed, the labor intensity is reduced and the abutting quality is greatly improved; and the middle connecting part with the rectangular cross section is capable of bearing high twisting moment so that the pipe tongs are incapable of sliding; therefore, the abutting efficiency is improved by more than 7 times.
Description
Technical field
The utility model relates to a kind of reinforcing steel bar connecting sleeve tube.
Background technology
The colligation of reinforcing bar construction is an important process in building operations at present, and the stud docking all is work high above the ground.The docking of the stud of prior art all is by docking sleeve, is screw threads in the same way because sleeve is two ends, can only a docking, but also to rotate the stud of top, and Active workings is dangerous, works heavy, and operating efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of clamping convenience, docking rapidly and reduces the amount of high-altitude operation steel reinforcement abutting joints sleeve arrangement of falling the plus thread.
For solving the problems of the technologies described above, the technical solution of the utility model is: the steel reinforcement abutting joints sleeve arrangement of falling the plus thread, comprise middle interconnecting piece, one end of described middle interconnecting piece is fixedly connected with the plus thread connector, the other end of described middle interconnecting piece is fixedly connected with down threaded connector, and the cross section of described middle interconnecting piece is rectangular.
As preferred technical scheme, the cross section of described middle interconnecting piece is square.
Owing to having adopted technique scheme, the steel reinforcement abutting joints sleeve arrangement of falling the plus thread, comprise middle interconnecting piece, one end of described middle interconnecting piece is fixedly connected with the plus thread connector, the other end of described middle interconnecting piece is fixedly connected with down threaded connector, and the cross section of described middle interconnecting piece is rectangular; The utility model can be avoided reinforcing bar binding being processed into the reinforcing cage of standard on the level land at high-altitude reinforcing bar binding butt-joint operation, then installs at overhead connection to get final product, and can guarantee personal safety, reduces labour intensity, and joint quality improves greatly; The torsional moment that the rectangular described middle interconnecting piece of cross section bears is large, and pipe wrench is skidded, and docking efficient improves more than seven times.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Among the figure: the 1-middle interconnecting piece; 2-plus thread connector; 3-falls threaded connector.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that do not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
As depicted in figs. 1 and 2, the steel reinforcement abutting joints sleeve arrangement of falling the plus thread, comprise middle interconnecting piece 1, one end of described middle interconnecting piece 1 is fixedly connected with plus thread connector 2, the other end of described middle interconnecting piece 1 is fixedly connected with down threaded connector 3, the cross section of the described middle interconnecting piece 1 of the present embodiment adopts the square structure form in the rectangle, the convenient manufacturing and clamping.
The present embodiment adopts the connection of falling the plus thread, advantage is that two reinforcing bar is motionless, middle by plus thread connector 2 and the threaded connector 3 of falling reinforcing bar is coupled together, can avoid at high-altitude reinforcing bar binding butt-joint operation, reinforcing bar binding is processed into the reinforcing cage of standard on the level land, then gets final product in the overhead connection installation, can guarantee personal safety, reduce labour intensity, joint quality improves greatly; It is large that cross section is the torsional moment that foursquare described middle interconnecting piece 1 bears, and pipe wrench is skidded, and docking efficient improves more than seven times.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the steel reinforcement abutting joints sleeve arrangement of falling the plus thread, comprise middle interconnecting piece, one end of described middle interconnecting piece is fixedly connected with the plus thread connector, and the other end of described middle interconnecting piece is fixedly connected with down threaded connector, it is characterized in that: the cross section of described middle interconnecting piece is rectangular.
2. the steel reinforcement abutting joints sleeve arrangement of falling the plus thread as claimed in claim 1 is characterized in that: the cross section of described middle interconnecting piece is square.
