The purpose of the invention is to create a post which can be anchored easily and safely in the ground. This is achieved according to the invention in that the through the Protrusion formed surface with the end of the post to be driven into the ground an angle of less than 9o ° includes, and that the projection with the side wall of the post is closed at the top and to the side Forms a pocket that is open in the direction of driving the post.

In the post according to the invention, the projections form, preferably in pairs, symmetrically to the post axis or arranged around them, a digging and compressing device. When driving the post will the soil is compressed in the angular range determined by the inclined surfaces below the projections, so that the part of the post located below the projections is surrounded by heavily solidified soil and is securely held will. Above the projections, channels form that can be filled with rammed earth. One special However, a secure connection of the post to the ground results when these channels are filled with liquid concrete will.

In the case of a post with an I-shaped cross-section, each projection is expediently formed from two plates, on both sides of the post between the profile

present and rest against the profile web, each Plate with the side wall of the post part of the pocket "forms the side of the inner surfaces of the profile web and the profile is not limited. The pocket formation is achieved here in the simplest way in that the profile parts are used to form pockets will.

For tubular posts, on the other hand, it is preferable to if the protrusion extends around the longitudinal axis of the post and the inclined surface is an inverted one, forms a funnel placed on the post, deyinit the Side wall of the post created the pocket. This creates a funnel-shaped pocket that surrounds the soil compacted completely evenly around the post.

According to an expedient development of the invention it is provided that the post is in different levels Has projections, wherein the projections of a higher level have an outwardly further inclined surface than that of a level below, viewed in the direction in which the post is driven. In this embodiment, the Projections in their width transversely to the post axis stepped in such a way that they are from the end to be rammed up seen to be wider. This results in a step effect when driving in, which allows it to be done with a smaller one Driving force to get along. During the ramming will be

first the channels formed by the lower projections and then the channels formed by the upper projections filled out.

The lowermost projection is advantageously arranged at a certain distance from the lower end of the post, this distance depending on the nature of the soil in which the post is driven. This remains below the lowermost projection a post section that is compressed in that of the lowermost projection Earth is held. The softer and less resistant this soil is, the longer it should be be protruding post section.

To set the post according to the invention one proceeds appropriately as follows that the post is driven into the ground by means of a suitable device such as a hammer device, furthermore in the extent to which the post is rammed into the ground, relatively liquid concrete into the length of the side wall or the Side walls of the post pours formed by the projections grooves, and that this concrete under the Effect of the blows exerted by the hammer device on the post shakes and lets itself sit.

In Fig. 1 Ms 3, a post 1 partially inserted into the floor 2 is shown. Der.Pfosten 1 has an I-profile. Between the legs 3 »4 · of the post 1, projections 7» 8 and 9 »10 are provided, distributed over its height, ie in planes denoted by 5 and 6, which preferably incline towards the lower end section 11 of the post 1 Plates are made. The projections -7 »8 and 9> 1o are arranged symmetrically in pairs on both sides of the web 12 of the profile. The projections 9 »1o of the upper level 5 are wider than the projections 7 ·> 8 of the lower level 6. The projections 9, 1o are located at a certain distance from the end 13 of the post 1, this distance depending on the nature of the Depends on the soil. It also depends on whether the end 13 is tapered to a point or not. The projections 7 »8 and 9, 1o are reinforced by supporting ribs 14 which are arranged in the longitudinal direction of the post 1 above the projections.

The post 1 is rammed into the ground by means of a hammer or striking device, not shown. Through the. In the position of the projections 7, 8, the soil in the area 15 is very strongly compressed at the wall of the post 1. As a result, this soil lies firmly against the end section 11 of the post 1 and forms a zone with very great resistance. The projections 7, 8 form at the same time when rammed into the

Bottom on both sides of the post 1 channel-shaped grooves the end. As the post is driven into the ground, these grooves 16 become relatively more fluid High quality concrete poured. By ramming the post and the vibrations caused by the hammer the concrete is vigorously vibrated and set. If the post 1 is driven further, so that the upper projections 9, 1o penetrate into the ground, so these ribs form 9? 1o on both sides of the post 1 also channel-shaped Punctures 17, which are wider than the punctures 16. As with these, so is also the punctures 17 concrete poured in that settles under the effect of the vibrations of post 1 «,

The concrete thus forms a good protection for the post and ensures good adhesion between the Post and the "neighboring soil As the concrete at

In Pig. 8 is also shown a tubular post, in which the projections of a plane through a Truncated conical bag pushed onto the post 19 are formed.

In IFig. 9 and 1o is as in B ¹ Ig. 6 to 8, a likewise tubular post 1 is shown, around which a multiplicity of identical projections 7, 8, 7 '? 8 ¹ , 7 ", 8" etc. of short length are arranged. These ribs are attached to mounting plates 18.

The invention is not limited to the illustrated embodiments. For example, the post can be made of be formed several pieces that are joined together when driving the post. This can do a lot long posts can be made without the need for major hammer mills. It is also conceivable that the Posts made of metal are replaced by posts made of reinforced concrete or wood, on which then the ribs in corresponding Way are attached.

All from the description and the drawings, including their structural details Features and procedural steps can also be found in any combination be essential to the invention.
