Definitions

  • the invention relates to a post according to the preamble of claim 1.
  • Such posts generally serve as load-bearing elements for objects of all kinds and can be designed in particular as ramming posts.
  • a ram post is driven with its lower end into a floor, so that the lower part of the pile post sunk in the ground and there is fixed in position fixed.
  • the upper part of the piling juts out over the floor surface so that objects can be placed there, which are then carried by the piling.
  • such posts may be provided at their lower ends with screw threads or the like.
  • Posts of this type can be used in a wide variety of applications. In principle, applications are conceivable in which a single post is provided, which alone carries an object, such as a poster or an advertising medium.
  • Posts are particularly frequently used in applications where several posts are required for the storage of articles.
  • An example of this are supporting structures for solar modules, which are designed in particular as outdoor facilities.
  • a series arrangement of Post needed, which are introduced into the soil.
  • the supporting structure consisting of an assembly of individual carriers, mounted, which then carries the solar modules.
  • a problem with such systems is generally a stable, strong anchoring of the posts in the ground, especially in the soil.
  • a more or less stable hold of the posts is obtained.
  • posts are anchored in a loose soil, only a small hold of the post is obtained.
  • the number of posts must be significantly increased so that despite the poor support of the posts in the ground, a secure storage of the support structure for the solar modules is obtained.
  • the disadvantage here is that due to the large number of posts required, the manufacturing costs of the entire system are undesirably high.
  • the invention has for its object to provide a post of the type mentioned, which is safely and firmly anchored there after ramming in a ground there.
  • the post according to the invention can be inserted with its lower end in a bottom, wherein in a set position introduced into the ground, a portion of the lateral surface of the post is sunk in the ground. At least one anchoring element is provided, which protrudes from the retractable surface in the ground.
  • Particularly advantageous post of the invention is designed as a ram post, which is rammed into a floor.
  • the post according to the invention at its lower end a screw thread, a rotary anchor or the like, so that the post is sunk by screwing in the ground.
  • the at least one anchoring element is locally obtained a cross-sectional broadening of the post, which may otherwise have a constant over its length cross section as known posts.
  • the at least one anchoring element is designed such that on the one hand does not hinder the insertion of the post.
  • the local cross-sectional enlargement, which causes the anchoring element, the friction between the post and the floor is increased significantly, whereby the support of the post in the ground is significantly improved.
  • anchoring elements are also arranged on the posts in such a way that, in addition, the posts are secured against tilting when external loads act.
  • the post according to the invention advantageously has a circular or polygonal, in particular rectangular cross section.
  • the lower end is advantageously pointed or sharp-edged in order to facilitate insertion of the pile post into the ground.
  • the ram post consists of a circular or polygonal metallic hollow profile whose lower edges have small cross-sectional areas, so that the ramming post can be easily inserted into the ground.
  • the ram post advantageously has a constant cross-section, so that the lateral surface forms a uniform, in particular cylindrical surface.
  • the inventive post can in principle also consist of a solid body, which may not necessarily consist of a metallic material but also of wood.
  • the one or more anchoring elements are advantageously made of a metallic material, in particular steel.
  • an anchoring element has a plurality of anchoring segments arranged offset in the circumferential direction of the post.
  • the anchoring segments of the anchoring element are rotationally symmetrical with respect to a rotation about the longitudinal axis of the post, that is, the anchoring elements are arranged in the circumferential direction of the Pfos- tens at equal distances from each other, whereby in the circumferential direction a symmetrical force absorption is achieved by the individual anchoring segments.
  • Anchoring segments of an anchoring element Essential for an efficient absorption of force of the anchoring segments of an anchoring element is that the anchoring segments protrude in the radial direction from the jacket surface of the post.
  • the anchoring segments cause a high cross-sectional enlargement of the post, wherein their axially projecting from the lateral surface of the post surfaces form large contact surfaces with the surrounding soil and thus ensure a good grip of the post in the ground.
  • an anchoring segment of an anchoring element on one or more wing segments wherein advantageously each wing segment extends in the direction of the longitudinal axis of the post.
  • a wing segment is generally designed in the form of a rigid, flat body, wherein one or each wing segment consists of a flat rectangular plate. Since the wing segments form planar elements which are aligned in the longitudinal direction of the post, the wing segments thus formed do not hinder the insertion of the post into the ground, since the small cross-sectional edges on the undersides of the wing segments do not present any great resistance to insertion of the post train in the ground.
  • Another advantage of the wing segments is that they have large cross-sectional areas at low volume, thus forming large contact surfaces with the ground, whereby a good and secure hold of the post is achieved in the soil.
  • an anchoring segment has one or more barbs.
  • the barbs are formed integrally with wing segments of the anchoring segment.
  • the barbs open at an angle to the respective wing segment.
  • these units can be made particularly efficient and inexpensive.
  • the angle of inclination of the barbs can be easily determined by bending over part of a wing segment.
  • the barbs are arranged on the upper side of the respective guide segment.
  • the barbs do not hinder the insertion of the post into the ground but, when the insertion of the post into the ground is completed, provide for a good hold of the post in the ground.
  • an anchoring element on the post is already sufficient to significantly improve the post's stability.
  • this has two anchoring elements, wherein a first anchoring element is arranged at the lower end of the post, and wherein the second anchoring element is arranged above the first anchoring element so that when rammed in the desired position post, the second anchoring element just below the bottom surface is arranged.
  • This arrangement is particularly advantageous in posts designed as a ram.
  • the lower anchoring element mainly causes an increase in the pull-out values of the post, while the upper anchoring element mainly secures the post against tilting when external forces act.
  • the post according to the invention can be used for applications of different types.
  • applications are conceivable in which only a single post is provided on which a single object is stored after insertion into the ground.
  • a plurality of posts are provided, which carry common objects after insertion into the ground.
