SUMMARY OF THE INVENTION It is an object of the present invention to provide a connector which can be used in a plurality of ways, in particular a connector which can be used for a plurality of different types of sheet piles.

[0004]

SUMMARY OF THE INVENTION The present invention comprises a central bridge element and two hook-shaped shoulders extending symmetrically from the longitudinal ends of the central bridge element, the shoulders having a central portion. Together with the bridging elements form two claws having a C-shaped cross-sectional shape, each claws having jaws open in opposite directions at right angles to the central bridging element, and furthermore at least the central bridging A sheet pile connector having a connector block extending from at least one longitudinal end of the element, the connector block having a neck portion and a head portion.

DETAILED DESCRIPTION OF THE INVENTION The connector according to the invention has a central bridge element, which is, for example, a strip-like element, with two shoulders extending symmetrically from the longitudinal end of the central bridge element. To form two claw sections of C-shaped cross section. Each tab together with the central bridge element forms an open jaw. Each jaw is perpendicular to the central bridge element and faces in opposite directions.
A connecting block extends from at least one of the longitudinal ends of the central bridge element, the connecting block having a neck portion and a head portion. The cross section of the connector of the present invention resembles a puzzle piece or a single stylized mannequin. The inner and outer contours of the cross section of the connector of the present invention are preferably a combination of a plurality of arcs. Hereinafter, embodiments of the connector of the present invention will be described in detail with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The connector 1 of the present invention has one central bridge element 2, and upper and lower longitudinal ends of the central bridge element 2 have shoulders 4 symmetrically with respect to a central plane 3 of the connector.
5 and 6, 7 are extended. Hook-shaped shoulders 4, 6, and 5, 7
Together with the central bridge element 2 form two pawls 8, 9 each having a C-shaped cross-section, each pawl 8, 9 forming an open jaw 10, 11. Nail parts 8 and 9 are central planes
It is divided into two parts symmetrical to each other by a cross section 12 perpendicular to 3 and passing approximately through the center line of the central bridge element 2. The jaws 10, 11 face in opposite directions.
On the extension of the longitudinal end of the central bridge element 2 this element
A connection block 13 is formed as an extension of the second block.
The connecting block 13 has a relatively narrow neck portion 14 and a relatively wide, substantially elliptical head portion 15 coupled to the neck portion 14. As shown by the dotted line in the figure,
At the longitudinally opposite end of the central bridge element 2, another connector block 13 having the same shape as the connector block 13 can be provided.

This connector is shown on the drawing at a scale of 1: 1. With two connector blocks 13, 13 ′, the connector 1 is symmetrical about the midplane 3 and symmetrical about the cross section 12. It will also be clear that the profile of this profile is obtained by combining a plurality of circular segments (arcs) having different radii. That is, the inner contour of the claw portion has a relatively large radius (for example, 20 mm) in the area of the central bridge element 2.
And a circle segment having a substantially small radius (eg, 8 mm) defining the pawls 4, 5, 6, 7 connected to the segment.
The outer contour of the claws is substantially parallel to the claws, and each shoulder has a thickness of about 10 mm. A circular segment having a relatively small radius (for example, 8 mm) that becomes the neck portion 14 is connected to the outer contours of the claws 4 and 5. The segment of the circle defining the upper head portion 15 has a larger radius (eg, 16 mm). Each segment of the circle other than the above is selected such that the transition portion describes a smooth arc.

In the direction of the center plane, the connector has a length of about 75 mm, the maximum dimension of the inner contour of the claws 8, 9 parallel to the center plane is about 28-30 mm, and the open contour parallel to the center plane. The length of the jaws is about 15mm. The thickness of the central bridge element near the cross section 12 is about 10 mm, the thickness of the connector block 13 near the one-sided section 14 is about 8 mm, and the maximum dimension of the head section 15 parallel to the cross section 12 is about 24 mm It is. The overall width of the connector in 12 transverse cross sections is about 60 mm. Of course, the above values can be varied. For example, the profile of the inner contour of the claw portion can be bent outward to have an oblong shape or the like.
