Definitions
- the invention relates to the joining of a pair of concrete reinforcing bars or rods or the like, in end-to-end relation.
- the invention concerns the joining of the bars in end-to-end relation by means of a two part connector in such a way that the tensile strength of the joint is not less than that of the bars or otherwise satisfies the requirements of a building code or regulation.
- the steps of the method may be performed in any sequence; the threaded parts may be interengaged before both sleeves are swaged on to the bars.
- the threads are parallel and/or inclined to the major axis of the sleeve, say by about 10 degrees.
- the threads may be of any suitable shape: threads of V section may be used; in some instances, e.g. for joining bars of relatively larger diameter, it is preferred to use square threads with sloping faces such as ACME threads.
- the lead of the threads may be greater than the pitch.
- the lead of the thread may be double, triple or higher; generally a double lead pitch is preferred.
- the two part connector especially the male part
- the male part of a material which can both be swaged and threaded without any decrease of strength. Steel is preferred.
- the male sleeve threaded part to be received in the female sleeve threaded socket one wishes to avoid an increase in the overall diameter of the sleeve assembly. This may involve a reduction in the cross-sectional area of the part of the male sleeve to be threaded.
- connection of two concrete reinforcing bars arranged in end-to-end relation a first sleeve being -waged to one bar and projecting towards the second bar, the sleeve having a bore with a threaded portion, a second sleeve swaged to the second bar and projecting towards the first, the second sleeve having an externally threaded end portion which is received in the threaded portion of the first sleeve.
- a two part connector adapted and dimensioned for use in joining together two concrete reinforcing bars, the connector comprising two sleeves, each sleeve having one end portion for swaging to a bar and another end portion for interengagement with the other sleeve, one of the sleeve engaging parts having a male extension and locating nose, the other sleeve having a female socket for reception of the male extension, the interengaging parts being threaded, and preferably the lead of the threads being greater than the pitch thereof.
- the concrete reinforcing bars range from about 10 mm to 57 mm in diameter.
- the bars may be of any type and have any rib deformation and are available under a variety of names.
- the bars B1 and B2 of Figure 1 are to be joined by ...eans of two sleeves S1 and S2.
- the sleeve S1 has a bore 1 with an unthreaded portion S1A which has been swaged on to the bar B1 and a threaded portion S1B, which has a screw thread 2 at one end, the right, as seen in Figure 1.
- the sleeve S2 has a portion S2A with an unthreaded bore 3 and the left hand end portion S2B has an internal thread 4, shaped and dimensioned to complement the thread 2 of the sleeve S1.
- the sleeve S2 is swaged onto the bar B2 and the thread 4 is then threaded into the threaded bore 2 of the sleeve S1.
- the assembled connection of the sleeves is of substantially uniform external diameter. which is an advantage.
- coupler S3, S4 two lengths of concrete reinforcing bars B1, B2 are to be joined by couplers S3, S4.
- One coupler S3, the male comprises a length of steel, originally having a straight sided end portion S3A, which as shown, has been swaged on to the bar B1, a threaded portion S3B, and a nose 7, the portions transist by an integral neck 5.
- the threaded portion S3B comprises threads 6 which have a multi- lead, ie. a double lead, so that rotation of a nut thereon moves two threads per full rotation.
- the nose 7 serves for location and alignment into coupler S4.
- the coupler S4 has an originally straight sided end portion S4A, and a socket end portion S4B which is internally threaded to receive the threaded portion S3B of the male coupler S3.
- the threads 8 of the socket S4B mate with those 6 of the male coupler.
- the mouth of the socket S4B has an internal chamfer to initially guide the nose of the male into the socket.
- one of the couplers S4, S4 is swaged to a bar -1, B2.
- the male coupler S3 may be swaged to the bar B1 in a fabrication shop.
- the female coupler is then swaged to the bar B2 and brought to the male coupler or vica versa, and by a few rotations the female is threaded on to the male so joining the bars together. (If the bar B2 is too long to rotate, the couplers may be joined and then the bar B2 may be swaged to the coupler S4).
- the joint formed meets the appropriate building code requirements. The joint is fast to assemble. It is easy for an operator to see that the couplers are properly'joined, since no full threads will be left exposed.
- the bars may range from U.S. size no. 4 (12 mm) to U.S. size no. 18 (57 mm).
- the invention is further illustrated by the following example.
- Two concrete reinforcing bars of diameter specified in the Table below were joined by appropriately dimensioned connectors according to Figure 2 above.
- the sleeves were swaged on to the bars and the splice was completed by threading the connector parts together to a hand tight connection and then unthreading the connection one half turn to simulate the situation where such unthreading may be necessary for example to join misaligned bars.
- the joint was then continuously tensioned under a load until the joint failed.
- the tensile strength was determined by dividing the maximum load by the nominal reinforcing bar area.
