Description
20~61 BACKGROUND OE INVENTION
Field of the Invention The present invention relates to a connecting system for interconnecting two elements together, and more particularly, to a universal connector which is securable to the end of concrete piles to interconnect these piles end-to-end.
Description of Prior Art It is known to interconnect concrete piles end-to-end by securing circular end caps in the end of the piles. At one end of the pile, a male connector cap is provided and at its opposed end, a female connector cap is provided. These connectors are interlocked together by steel rods which are power driven into a circular channel formed about the connectors when mated with one another. A disadvantage of such connecting system is that a power tool is required to drive the interconnecting steel rods within these channels as the channels have a curvature. Also, once the steel rods are driven in the channels, it is extremely difficult to remove the rods therefrom and, therefore, it is time-consuming to disconnect the piles, if this is required. Also, these steel rods can break in the channel and make it extremely difficult then to disconnect the piles. In such a case, it would be necessary to cut the connectors with a torch or with other type power tools and thereby destroying the piles.
Furthermore, with these connectors, it is necessary to have both a female and a male type connector for each pile and the construction is therefore more complex and ~ 2~5561 costly and care must be taken during the construction of each pile to make sure that the proper connector is secured at both ends of the pile.

BRIEF DESRIPTION OF DRAWINGS
A preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which:
FIGURE 1 is a perspective fragmented view of the connecting system of the present invention as used for interconnecting two concrete piles end-to-end;
FIGURE 2 is a cross-section view illustrating the construction of the locking channel formed by two connector plates positioned one on top of another;
FIGURE 3 is a section view showing the configuration of the locking bar; and FIGURE 4 is an exploded view showing the assembly of the connecting system for interconnecting two concrete piles end-to-end.
DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, and more particularly to Figure 1, there is shown generally at 10, the connecting system of the present invention for interconnecting two elements, herein concrete piles 11, together and in an end-to-end relationship. The connecting system comprises at least two identical connector plates 12 and 12' each having an outer flat surface 13 and at least two straight edge sections 14 (see Figure 4) of predetermined length. As herein shown, the plates have a polygonal contour thereby providing 2~5~61 eight straight edge sections 14. It is also conceivable that the piles and connectors could be of triangular cross-section.
Referring now additionally to Figures 2 to 4, it can be seen that at least two opposed ones of the straight edge sections 14 are provided with locking grooves 15, four of these being shown in Figure 4 and which are formed all along the straight edge sections 15.
As can be more clearly seen in Figure 2, these locking grooves 15 extend to the outer flat surface 13 of the connector plate 12.
As shown in Figure 2, the locking groove 15 is a rectangular cross-section groove formed along the straight edge sections 14. The groove defines a clamping cavity 16 of rectangular cross-section and formed as an undercut cavity which is spaced below the outer flat surface 13 and formed in a vertical edge wall 17 of the locking groove. Retention cavity 18, also of rectangular cross-section, is disposed in a horizontal edge wall 19 of the locking groove.
When both plates 12 and 12' are positioned in alignment with their flat surfaces 13 in contact with one another and their locking grooves 14 aligned, the locking grooves 15 formed in each of the plates 12 and 12' thereby form a locking channel 20. In order to interlock the plates 12 and 12' together, a straight locking bar 21 is slidingly insertable in the channel 20 from an end of the channel.
20~5561 Referring now more specifically to Figure 3, there is shown the cross-section configuration of the locking bar 21. As herein shown, the locking bar is a straight bar provided with two elongated spaced-apart parallel ribs 22 extending along an inner wall 23 thereof and these ribs 22 constitute clamping protrusions which are received in the clamping cavity 16 to interlock the plates 12 and 12' together. The locking bar 21 is also provided with an elongated straight shoulder 24 extending along opposed side walls 25 of the bar and extend coextensive therewith in alignment with the longitudinal axis of the locking bar. The bar also has a flat outer wall 26 so that when positioned within the locking channel 20, this wall 26 is disposed in flush alignment with the straight wall section 27 on opposed sides of the locking channel 20 not to cause any outer interference with the pile.
Referring again to Figures 2 and 3, it is pointed out that the thickness "a", "c" and "d" of the ribs 22 is calculated to take stresses in the locking bar due to axial load and/or the bending moment of piles interconnected together. The distance "b", which is also the distance between the ribs 22, is the combined distance of the vertical edge wall 17 of two plates 12 and 12' joined together, is calculated to take stresses in the plates due to axial load and/or the bending moment of the interconnected piles. The locking bar 21 is dimensioned for close friction fit within the locking channel 20 and they are insertable therein by the use of a hammer and accordingly no special pneumatic or electric l 2055561 tools are necessary to interconnect these connector plates together. The plates and the locking bar are constructed from steel material. Once the locking bar is inserted in the locking channel 20, it is then arrested therein by a threaded lock pin 30 which extends in a threaded bore 31 formed in the flat outer wall 26 of the locking bar 21 and extends therethrough. The lock pin 30 has an arresting inner end 32 to engage with a vertical wall 17 of the locking channel 20 and is engageable by an Allan key.
As shown more clearly in Figures 1 and 4, the connector plates 12 and 12' are each provided with alignment means in the form of an alignment pin 33 which is disposed in aligning cavities 34 and 34' of opposed connector plates 12 and 12' and centrally located in the plates whereby these plates are perfectly aligned with one another. In order for the locating grooves 15 to also be aligned perfectly with one another, there is also provided an anti-rotation means in the form of a further pin 35 (see Figure 4) which is insertable in further locating holes 35 and 35' provided in the outer surfaces of both plates required to be interconnected. Thus, the plates are perfectly positioned with respect to one another with their locking grooves 15 aligned to form the locking channels 20.
On the side opposite the outer flat surface 13, herein outer side wall 36, there is provided attachment means to secure the concrete piles and in the form of anchoring reinforcing rods 37 which are each formed with a securing end 38 which may be of enlarged cross-section 2055~61 and provided with a thread 39 thereabout. Accordingly, the connecting end of the reinforcing rods 37 is not weakened by having a reduced cross-section, if these rods did not have an enlarged end and with threads having been formed therein. This threaded securing end 38 is connected to the outer side wall 36 in threaded bores 40 spaced apart circumferentially therein. The outer side wall 36 is further provided with a plurality of bores 41 extending therethrough and which are aligned with one another when two plates, such as plates 12 and 12', are interconnected together whereby to permit passage for steel cables (not shown) which are utilized to prestress the concrete piles. A skirt 42 is welded about the contour of the connector plates to form connector caps for securing two opposed ends of the concrete piles. In fact, when the piles are formed, the concrete is poured in these caps.
Although the preferred embodiment herein illustrates the connector plates as used in forming end caps of concrete piles for interconnecting the piles end-to-end, it is also within the ambit of the present invention to utilize the connector plates to interconnect other elements together. For example, the connector plate 12' may be embedded in a concrete bed and the other connector plate 12 may be secured to the bottom of a post, such as a lamp post, to interconnect it to the bed.
With this method, the post could be easily connected and disconnected and holes could be provided in the plates and along the posts for the passage of electrical wiring.
Many other uses are foreseen for these connecting plates 20~5~61 to interconnect elements together. The mechanical connector can also be designed and used to support a compression force, a tension force, and a flexural force as well as a combination of an axial force and a flexural force. As pointed out above, the machining of the locking grooves 15 is simple as it extends along a linear axis only. This provides two advantages and namely, that the machining is limited to a small number of operations, making the machining more expedient at a reduced cost, and secondly, the mechanical tolerances are reduced to a minimum (as dictated by field installation), and thereby providing a more effective mechanical behaviour to withstand the load. Because the locking groove is located on the outer edge of the plates that are joined together, it provides for a maximum resistance to a bending moment.
It is within the ambit of the present invention to cover any obvious modifications of a preferred embodiment described herein, provided such modifications fall within the scope of the appended claims.
