Definitions
- the present invention relates to a connecting device for joining end to end two bars whose at least the ends are threaded, intended in particular but not exclusively, for the building industry.
- US-A-4,081,219 describes a coupling of the ends of two cables or benches allowing a pre-tension to be established thereon.
- a hollow socket In a hollow socket are mounted two threaded rings in one of which is screwed the end of a cable while the end of the second cable is screwed in a stop piece bearing on the second ring. But these connections do not make it possible to make up for the misalignments mentioned above.
- the object of the present invention is to overcome these drawbacks and to allow the end-to-end connection of immobilized bars when these are not exactly aligned and / or do not come into contact with each other or when the bars axes have a relative inclination.
- the end-to-end connection device for two bars comprising a hollow socket intended to receive the ends of the two bars, at least one end of the socket being threaded, a hollow nut allowing the axial passage of a bar being screwed onto said end, characterized in that it comprises at least one stop piece fixed to the end of a bar coming into contact with the internal face of the nut, the external transverse dimensions of the stop piece being smaller to the internal transverse dimensions of the sleeve.
- the abutment part has a clearance inside the bushing which allows make up for misalignments for example of the order of 1 to 2 centimeters.
- connection device can be symmetrical, the sleeve being tapped or threaded at its two ends. It can also be disy etric and in this case, the structure of the socket is generally more complex.
- the socket is of generally hollow cylindrical shape and the external diameter of the abutment piece is less than the internal diameter of the socket.
- the bars are quick step bars used in the building industry and known, for example, under the names of "DYWIDAG” or "GEWI" (Trademarks).
- certain elements are threaded at a pitch conforming to the ISO standard for example.
- the invention is independent of the mode of threading or tapping.
- the abutment pieces consist of sleeves which are screwed on. the ends of the bars.
- these stop pieces can also be crimped or welded rings in the workshop before assembly on site.
- FIG. 1 there is a cylindrical sleeve 1. Inside this sleeve, are included the ends of two bars, respectively 2 and 12, which are aligned and in contact with each other. On the end of the bar 2 is screwed, by a thread 6, a sleeve 4 or stop piece, the external surface of which is cylindrical and smooth. As shown in the figure, the sleeve 4 is slightly set back from the contact plane between the bars 2 and 12 so as to release a space 9. The second end of the sleeve 4 is in contact with the internal face of a nut 3 The nut 3 is screwed into the socket 1 by an ISO thread 5. Likewise, on the other side of the socket, the nut 13 comes to bear against a sleeve 14 which is screwed by a rapid pitch tapping on the bar 12.
- the diameter of the sleeves 4 and 14 is less than the internal diameter of the sleeve 1 and releases a space 7 allowing an alignment take-up.
- the nut 13 is screwed onto the sleeve 1 by a thread 6.
- the threads 5 and 6 are threaded in opposite directions, that is to say that if the thread 6 is on the left, the thread 5 is on the right for ensure mutual blocking. If the step difference between the two nets 5 and 6 is important, we can, if need be, carry them out in the same direction.
- the internal non-threaded diameter of the nuts 3 or 13 is greater than the diameter of the bars 2 and 12 so as to allow a connection of these bars with respect to one another when the latter are not aligned.
- the assembly is symmetrical and the socket D is tapped according to the ISO standard at its two ends.
- the sleeves 4 and 14 are externally cylindrical and enter the sleeve 1 with a very large clearance. It is thus possible to make up for a misalignment of the order of one centimeter, for example.
- the nuts 3 and 13 are threaded on the outside and are screwed inside the socket. They can be tightened by a hexagon and the clearance of the rod or bar 2 or 12 is equal to that which was created between the sleeve 1 and the sleeves 4 and 14. The assembly of the assembly is ensured by the sleeve 1 .
- Figure 2 which is similar to Figure 1 shows the mounting of two non-aligned bars.
- the sleeve 14 can come into contact with the internal surface of the sleeve 1.
- the connection nevertheless remains as strong as ever.
- the sleeves 4 and 14 are not in contact with each other and prestressing can be applied by means of a wrench to the two nuts 3 and 13.
- the ends of the bars are always in contact with each other, on a sufficient surface.
- FIG 3 there is shown another embodiment which differs from the first only by the shape of the nut 23.
- the sleeve 1 is externally threaded at its two ends and the nut 23 is tapped so as to be able to screw on the outside of socket 1.
- the other part of the connection (not shown) is perfectly symmetrical.
- This type of nut makes it possible to have a connection device slightly shorter than in the previous example but whose radial size is greater. The choice of nut type therefore depends on the work to be carried out.
- the mounting method is as follows: firstly, the nut 3 or 23 is placed on the rod 2. Given the significant play existing, the nut moves freely on the rod and possibly can fall until it is held, for example, by a concrete block with reinforcements waiting to be connected to upper reinforcements. The sleeve 4 is then screwed onto the bar 2, leaving a clearance 9 so that the bars actually come into contact with one another. Then the sleeve 1 is slid around the bar 2 until it comes onto the nut 3 or 23.
- the nut 13 is then slid onto the bar 12 and then the sleeve 14 is screwed to the front end of the bar 12, the thread being a quick pitch thread.
- the socket is positioned and the two nuts 3 and 13 are then brought together and are screwed inside the socket.
- the screwing is stopped by the abutment of the nuts against the external faces of sleeves 4 and 14 respectively.
- a prestress is then applied using a torque wrench, the contact of the sleeves 4 and 14 on the nuts 3 and 13 avoiding any separation of the bars 2 and 12. The forces are transferred to the bush 1.
- FIG. 4 represents an alternative embodiment in which the device is no longer symmetrical. That is to say that the sleeve 11 has an internal thread by which it is screwed at the end of the rod 12. As before, the nut 3 is slid over the bar 2 and the sleeve 4 is screwed (with rapid pitch) onto the end of rod 2. These operations are, of course, carried out before the ends of the bars are brought together. In this case, the sleeve 11 has on one of its ends a hexagon. In the example shown, the two bars 2 and 12 are in end-to-end contact. The sleeve 4 is not in contact with the groove formed inside the sleeve 11 and a space 9 remains in front of the sleeve 4. In fact in this embodiment the nut 13 has been somehow integrated into the socket. But, of course, we can only make up for half of the misalignment that we could correct in Figure 1.
- FIG. 5 represents a connection device in the case where the ends of the bars cannot come into contact with one another.
- the connection device can somehow make up for the difference in height in the case of a vertical connection or the difference in length of the two bars.
- the socket 1 the ends of which have two ISO 5 threads.
- nuts 3 and 13 are screwed into these threads, but the ends of the two bars 2 and 12 are not in contact.
- Sleeves 4 and 14 are screwed, with rapid pitch, on the ends of the bars 2 and 12.
- this assembly it is essential to provide a blocking for example by means of the locknuts 15 intended to ensure a prestressing between the bars 2 and 12 and the sleeves 4 and 14 which are face to face and bear one against the other by tightening the nuts 3 and 13.
- the mounting method is the same as above except that the sleeves 4 and 14 project from the ends of the rods.
- length of the threads 5 must be provided for being used only in part and it is necessary to determine beforehand a maximum distance between the bars so that a sufficient number of threads are engaged.
- the sleeves 4 and 14 touch each other and their length defines the depression of the nuts 3 and 13 inside the sleeve 1. In this case, there remains a space 10 between the bars 2 and 12.
- the sleeves are blocked by the nuts 3 which are themselves locked by the locknuts 15. In this assembly,. the prestressing is exerted on the sleeves and not on the bars.
- the abutment parts consist of sleeves 4, 14.
- the present invention can be implemented with bars of non-threaded concrete steel.
- the abutment pieces constituted by rings or the like are joined together in the workshop with the end of the bars by crimping, welding or even forging, after insertion of a nut 3 or 13.
- the radial dimensions of the rings or other added elements must be less than the internal diameter of the sleeve in order to allow clearance.
- the sleeving according to the invention can be filled with grease, a cement or resin grout, either during assembly, or by injection through a hole drilled in the socket.
- the invention also allows the connection of bars of different diameters.
- the connecting device is characterized in that the rear face of at least one of the sleeves is curved so as to be able to bear on the nut in an angular position varying by a few degrees around the axis of the nut.
- Figure 6 shows in vertical section such an arrangement.
- the sleeves 4, 14 are frustoconical and have a curved rear face 16 resting in a bowl 17 formed inside the nuts 3, 13.
- the bearing surface of the sleeves on the front face of the nut is no longer flat but is more or less spherical.
- the body of the sleeves. 4, 14 is of generally frustoconical shape to allow maximum angular displacement inside the bush 1 and with respect to the axis of the latter.
- the front part of the nut receiving the convex face 16 of the sleeve is shaped into a bowl 17 to ensure a better, substantially ball-and-socket type bearing of the sleeve against the nut.
- the two sleeves of the same device can have the same structure or be different.
- the sleeve can in certain cases be crimped at the end of a threaded bar or not. It is also possible to forge at the end of one or both bars a protuberance intended to ensure the function of the sleeve, that is to say essentially the contact with the nut.
