Abstract
A drive-in post-support with a drive-in spike 2 having a plurality of wings includes a sleeve 1 welded to the upper end of the wings. Each wing has at its upper end an inward re-entrant step 4, the edge 5 of which is adapted to the internal dimensions of the sleeve, and the sleeve rests on the steps and is welded at least to the upper end of each step edge 5, e.g. at 9. An internal socket 7 for receipt of a driving tool 13 may be provided by steps 6 in the wings. <IMAGE>
Description
Drive-in Ground Sleeve
This invention relates to a drive-in ground sleeve with a drive-in spike having a plurality of wings and with a sleeve welded to the upper end of the wings.
Drive-in ground sleeves of this type are used for receiving posts or stakes. In this case the sleeve may have a base wall which is welded to the end faces of the wings. It is also known from EP-B-O 150 946, to insert the front edges of the wings into slots in the base of the sleeve in order to give the welding seams greater strength. The capacity of the welding seams for loading by tilting moments, however, is insufficient.
The object of the present invention is to provide an improvement of the drive-in ground sleeve with respect to tilting loads.
According to the present invention, there is provided a drive-in ground sleeve with a drive-in spike having a plurality of wings and with a sleeve welded to the upper end of the wings, wherein each wing has at its upper end an inward re-entrant step, the edge of which is adapted to the internal dimensions of the sleeve, and in that the sleeve rests on the steps and is welded at least to the upper end of each step edge.
Embodiments of the invention differ from the state of the art in that the sleeve is centred with its end face on the spike on the one hand and is welded to the spike at the upper ends of the step edges on the other hand. The join has therefore a high degree of stability and as a result of the long guiding can absorb high tilting loads.
A stable and loadable weld is attained by the sleeve wall having holes orientated in each case towards the upper end of a step edge in order to receive the welding compound.
The step edges can be used for additionally holding the respective stake in that four wings are arranged in the manner of a cross for receiving a cruciform slot in a post. In this way, a drive-in ground sleeve can be provided for different supports of stakes or posts. The greater support leads to greater stability.
For centring and orientating the drive-in ground sleeve it is provided that each wing has an internal step at the top.
Driving-in is facilitated by a cylindrical drive-in pin fitting into the recess formed by the internal steps.
The fact that a cap engaging over the sleeve opening is provided with a central passage for guiding the drive-in pin ensures the guidance of the drive-in pin.
The present invention will now be further described with reference to the accompanying drawing, in which:
Fig. 1 is an elevation, partly in section, of the drive-in ground-sleeve with a drive-in pin, and
Fig. 2 is a plan view of Fig. 1.
The drive-in ground sleeve comprises a sleeve 1 and a drive-in spike 2. The drive-in spike 1 comprises wings 3 which are arranged in a stellar shape and which are welded together and terminate in a point. Four wings in a cruciform arrangement are illustrated in the drawing. In the form illustrated, the sleeve 2 has a round cross-section. Depending upon the stakes to be received, the cross-section can also be square, polygonal or any other shape.
Each wing 3 is offset towards the inside by a step 4 in the upper region. The step edge 5, which is orientated approximately parallel to the axis, is set back accordingly. An internal step 6 is provided on the top of each wing. The internal steps 6 together form a recess 7.
The internal diameter of the sleeve 1 corresponds to the diameter of the circle formed by the step edges 5, so that the sleeve can be pressed onto the step edges 5 and rests on the steps 4. Elongate holes 8, which are each orientated towards the upper end of a step edge 5 and which are filled by welding compound 9, are provided in the wall of the sleeve, so that the sleeve 1 is anchored securely on the steps 4 by the said welding seams. The holes 12 in the wall of the sleeve 1 are intended for fastening elements for a post or stake. The post stands with its base surface on the upper edges of the wings 2.
It is possible to increase the support of the post by sawing a cruciform slot, into which the steps of the wings enter during insertion, in the base surface of the post.
In this way, the support is increased and, in addition, the strength of reception is improved by the positively locking guidance. It is therefore possible to use a drive-in ground sleeve for different degrees of support and thereby reduce the number of types and the cost of storage.
The sleeve 1 rests on the steps 4 with positive locking.
In addition, the welding seams form an integral join.
Since the elongate holes are at a considerable distance from the re-entrant face of the steps, the welded join has a high degree of stability.
A cover 10 with a central passage 11, which can be placed on the end face of the sleeve 1, is provided as a drive-in aid. A stable, cylindrical drive-in pin 13 can be passed through the passage 11 and fits into the recess 7. The drive-in ground sleeve can be driven into the ground by a hammering tool acting upon the drive-in ground sleeve pin 13.
