Abstract
The utility model discloses a connection structure of construction steel bar, it includes reinforcing bar head one and reinforcing bar head two, and it still includes the adapter sleeve, the periphery of reinforcing bar head one and reinforcing bar head two is equipped with the screw thread, also be equipped with the screw thread on the inner wall of adapter sleeve, the screw thread of reinforcing bar head one, reinforcing bar head two and the screw thread phase-match that connects the adapter sleeve inner wall, connect the adapter sleeve in the reinforcing bar head one, reinforcing bar head two outsides. The screw thread on the periphery of the first reinforcing steel bar head is opposite to the screw thread on the periphery of the second reinforcing steel bar head. Preferably, the thread valley bottom of the thread on the periphery of the first reinforcing steel bar is level with the outer wall of the reinforcing steel bar; the thread valley bottom of the thread at the periphery of the two reinforcing steel bar heads is also equal to the outer wall of the reinforcing steel bar. By adopting the scheme, the two reinforcing steel bar heads are connected through the connecting sleeve threads, the influence on the strength of the reinforcing steel bar by the traditional high-temperature welding is avoided, and the circle centers of the two reinforcing steel bar heads are not deviated.
Description
Technical field
The utility model relates to a kind of syndeton, the syndeton of a kind of building iron of more specifically saying so.
Background technology
In building construction process, need the reinforcing bar of certain-length for certain building unit, therefore reinforcing bar needs splicing sometimes.The joining seam welding has been adopted in traditional reinforcing bar connection.Mainly there are following two aspect deficiencies in the joining seam welding method: the one, and the high temperature during welding has produced influence to the intensity of reinforcing bar; Therefore the 2nd, the center of circle of two steel bar ends that join has deviation, to tend to cause spacing inhomogeneous connecting.
The utility model content
At the problems referred to above, the center of circle that the problem that the utility model quasi-solution is determined provides a kind of two steel bar ends do not have deviation, without the syndeton of the building iron of high-temperature soldering.
For achieving the above object, the utility model is by the following technical solutions: a kind of syndeton of building iron, it comprises the first and steel bar end two of reinforcing bar, it also comprises adapter sleeve, described reinforcing bar is first to be provided with screw thread with periphery steel bar end two, also be provided with screw thread on the inwall of described adapter sleeve, described reinforcing bar is first, the screw thread of the screw thread of steel bar end two and adapter sleeve inwall is complementary, and described adapter sleeve is first at reinforcing bar, the outside of steel bar end two.
The hand of spiral of the screw thread of the first periphery of described reinforcing bar and steel bar end two peripheries is opposite.
As preferably, equal at the bottom of the groove of thread of the screw thread of the first periphery of described reinforcing bar with the reinforcing bar outer wall; Also equal at the bottom of the groove of thread of the screw thread of described steel bar end two peripheries with the reinforcing bar outer wall.
Adopt such scheme, the syndeton of a kind of building iron of the present utility model, two steel bar ends are threaded by adapter sleeve, avoided traditional high-temperature soldering to influence the intensity of reinforcing bar, and the center of circle of two steel bar ends do not have deviation yet.The adapter sleeve screw thread also can suitably be regulated length of said joint.The hand of spiral of two steel bar ends is opposite, makes the connection of reinforcing bar more convenient.Equal at the bottom of the groove of thread of the screw thread of two steel bar end peripheries with the reinforcing bar outer wall, guaranteed the intensity in the bar splice, concrete operations before making the steel bar end screw thread, are carried out axial forging and pressing to the aluminium head earlier together, make its diameter chap.
Description of drawings
Fig. 1 is the structural representation of the syndeton of building iron of the present utility model.
Among the figure, the 1-muscle is first, 2-steel bar end two, 3-adapter sleeve, 4, the 5-screw thread.
The specific embodiment
As shown in Figure 1, the syndeton of building iron of the present utility model, it comprises reinforcing bar first 1 and steel bar end 22, and adapter sleeve 3, the periphery of described reinforcing bar first 1 and steel bar end 22 is provided with screw thread 4.It is opposite that the screw thread 4 of the screw thread 4 of first 1 periphery of reinforcing bar and steel bar end 22 peripheries is preferably direction.Also be provided with screw thread 5 on the inwall of described adapter sleeve 3, described reinforcing bar is first 1, the screw thread of steel bar end 224 is complementary with the screw thread 5 that connects cover 3 inwalls, and described adapter sleeve 3 is first 1 at reinforcing bar, steel bar end 22 outsides.
As improvement, the syndeton of the utility model building iron, equal at the bottom of the groove of thread of the screw thread 4 of first 1 periphery of described reinforcing bar with the reinforcing bar outer wall; Also equal at the bottom of the groove of thread of the screw thread 4 of described steel bar end 22 peripheries with the reinforcing bar outer wall.
