Definitions

• the invention relates to a device for the vertical arrangement of a pole-shaped or post-shaped object on a base-side fastening device, according to the preamble of claim 1.
• fastening devices which can be anchored in the ground and which then have the pile or carry post-shaped object.
• the fastening device which can be anchored in the ground comprises, for example, a screw or screw which is screwed into the ground in the manner of a corkscrew, after which the post or post is then screwed to this fastening device or inserted into it.
• DE-GM 93 13 260 proposes an adjusting or adjusting device between a fastening device that can be anchored in the ground, for example a ground screw, and the pile-shaped or post-shaped object to be fixed thereon.
• this adjusting device essentially comprises a cylindrical, elongated holding mandrel which projects upwards from the free upper side of the fastening device and which can be inserted into a receiving bore on the underside of the pole or post-shaped object.
• the axial length of the holding mandrel and the depth of the receiving bore are chosen so that the former is somewhat longer than the latter, so that when the pile-like or post-shaped object is placed on the holding mandrel, its free end sits on the bottom of the mounting hole.
• the pile-shaped or post-shaped object is now - if necessary with the help of a plumb line or a spirit level - aligned exactly vertically, after which one or more blows are applied to the upper end of the object, so that the free end of the holding mandrel is in the bottom of the blind hole digs in and so the object is fixed in position in relation to the fastening device in its exactly vertical orientation.
• DE-GM 93 13 260 The subject of DE-GM 93 13 260 has proven itself in practice; Nevertheless, he is also responsible for the lack of detail that, due to the tight, form-fitting grip of the pin by the material of the post or post, the post shoe itself must be anchored exactly vertically in the ground in order to ensure that the post or post held thereby is in a vertical position.
• the DE-GM 93 13 260 proposes adjustment devices between the post and the fastening device in further embodiments in order to be able to align the post exactly vertically even when the fastening device is sitting obliquely or obliquely in the floor, these adjustment devices are rather complex and therefore expensive.
• This known device comprises a base-side fastening device in the form of an anchoring part which can be anchored in the ground or in a foundation and a support part arranged thereon and which can be positively engaged with the post or post.
• the support part is in this case designed as a vertically extending pin which is held in a recess on the underside of the post in such a way that the post closely surrounds the pin on the circumference, that is to say practically in a form-fitting manner.
• a contact surface or support surface is also provided.
• the support plate for the post, from the level of which the pin protrudes upwards and on which the bottom of the post rests.
• the support plate also has a circumferential ring gear which digs into the face by applying impact to the upper end of the post and offers a positional fixation in the transverse direction.
• a transverse pin is provided which horizontally penetrates both the material of the post and the material of the pin.
• the post shoe according to DE-GM 89 03 236 can be used to solve the problem there and also essentially no problems with loosening the fastening device are to be expected, since the post - with the exception of the impact on the upper end - essentially is pushed force-free onto the spigot, but this post shoe or this fastening device again has the essential disadvantage that the post shoe itself must be anchored exactly vertically in the ground due to the material of the post or post due to the tight, positive engagement of the post Ensure the vertical position of the post or post held with it.
• the post shoe according to DE-GM 89 03 236 can also cause problems with loosening of the base-side fastening device if the material of the post or pile is particularly hard, so that the pressing of the ring gear into the end face of the post or post is a problem requires some effort.
• the blow or blows with which the pile-like or post-shaped object is fixed to the fastening device then must / must be rather strong to achieve the necessary holding forces for the object.
• the fastening device can therefore in the worst case - especially in loose soil or sand - tend to loosen up again through these blows, so that there is a risk of higher forces acting on the object that it loses its vertical orientation or even tips over.
• a device for the vertical arrangement of a pile-shaped or post-shaped object on a base-side fastening device has become known from PCT / EP 96/03704.
• This generic device consists essentially of a substantially cylindrical, elongated holding mandrel, which projects upwards from the free top of the fastening device and which can be inserted into a receiving bore on the underside of the pole or post-shaped object; and a support plate, which is separate from the fastening device and can be fastened to the lower end face of the pile-shaped or post-shaped object, from which at least one fastening projection projects upwards, which presses into the material of the pile-shaped or post-shaped object, wherein the support plate is centered on the cross-section of the holding mandrel has at least partially adapted opening, the holding mandrel being considerably thinner than the receiving bore on the underside of the pile-shaped or post-shaped object.
• the fastening device known from PCT / EP96 / 03704 is further developed in that a clamping section comprising the central opening is arranged on the support plate in the same direction as the at least one fastening projection.
• This Clamping section increases the contact surface between the holding mandrel and the support plate considerably compared to a support plate provided without a clamping section, so that far greater holding forces can be achieved which hold the pile-like or post-shaped object securely even against high acting forces.
• the holding mandrel and the opening preferably each have a round cross section. This makes it possible to rotate the pile in relation to the holding mandrel and thus the fastening device, so that, for example, any components attached to the pile and projecting radially therefrom can be brought into the desired orientation.
• the clamping section can preferably be at least partially applied with its outer circumference to the circumferential wall of the receiving bore. This results in an even better absorption and introduction of force from the pile-shaped or post-shaped object via the support plate into the fastening device.
• the holding mandrel preferably tapers conically from the free surface of the fastening device toward its free end. Together with the further preferred embodiment that the holding mandrel has an outer diameter adjacent to the free surface of the fastening device, which slightly exceeds the inner diameter of the clamping section, this creates the possibility that a particularly firm circumferential for and / or non-positive system.
• clamping section is also in the form of a cylindrical and circumferentially at least once in the axial direction device slotted sleeve is formed by the conically widening downward mandrel in the course of its penetration into the sleeve, a radial expansion of this sleeve, so that it can apply to the inner peripheral wall of the receiving bore under force or pressure.
• the sleeve is particularly preferably slotted equidistantly several times in the axial direction in such a way that a plurality of tongues projecting from the support plate and encompassing the central opening are formed.
• these tongues are expanded or pressed evenly radially outward, so that there is an intimate and resilient connection between the pile or post-shaped object, the support plate and the holding mandrel or fastening device.
• a plurality of fastening projections preferably protrude upward from the support plate.
• fastening projections are preferably designed in the form of conically tapering tips, so that they can easily dig into the material of the object.
• the fastening protrusions are evenly distributed on at least one circle concentric with the opening, in particular the radially widening sleeve absorbs forces acting outward in the object from the fastening protrusions, so that there is a risk of tearing or splitting the lower end of the object is significantly reduced. Further details, aspects and advantages of the present invention result from the following description of several embodiments with reference to the drawing.
• Fig. 1 is an exploded view of an embodiment of the present invention in a disassembled state
• Fig. 2 is a plan view from above of an embodiment of a support plate.
• Fig. 1 shows an embodiment of the present invention for vertically arranging a pole or post-shaped object (hereinafter referred to as "post") on a bottom-side fastening device.
• post a pole or post-shaped object
• FIG. 1 shows an embodiment of a device 2 according to the invention, which is used for the vertical arrangement of a post 4 on a fastening device 6 that can be anchored in the ground, for example.
• the fastening device 6 can, for example, be buried in the ground or concreted in, or preferably screwed into the ground in the manner of a corkscrew.
• a particularly preferred embodiment of the fastening device 6 is described in DE-GM 93 13 258 by the same applicant. Reference is hereby made in full to the disclosure content there.
• the device 2 shown in FIG. 1 it has a recessed area or shoulder 8 at the upper free end of the fastening device 6 which carries a tubular holding mandrel 10 in the center.
• the outer diameter of the holding mandrel 10 is significantly smaller than the inner diameter of a receiving or blind bore 12 which is formed at the lower free end of the post 4.
• the depth of the bore 12 is preferably less than the height of the holding mandrel 10.
• a support plate 16 can be arranged between the shoulder 8 and an end face 14 of the post 4, where the bore 12 is made.
• the shape and area of the support plate is preferably adapted to the shape and area of the end face 14, that is to say as a rule circular, as shown in FIG. 2.
• From the top of the support plate 16 at least one, preferably a plurality of fastening projections 18 point upwards in the direction of the end face 14.
• a plurality of prong, prong or thorn-shaped fastening projections 18 can extend upwards from the support plate 16, these fastening projections according to FIG. 2 preferably being arranged on one or more concentric circles 20 and 22 lying equidistant from one another are.
• the support plate 16 has a central opening 24 which is formed in the support plate 16 so that it is substantially aligned with the bore 12 in the lower end portion of the post 4 after the attachment of the support plate 16 on the end face 14.
• the central opening 24 in the support plate 16 is surrounded by a clamping section 26.
• the clamping section 26 essentially has the shape of a sleeve 28 which is divided in the axial direction, but is preferably divided several times by slots 30, so that the Sleeve 28 is divided into a plurality of tongues 32 depending on the number of slots 30.
• four slots 30 are provided, which are spaced apart from one another evenly on the circumferential side by 90 °, so that four tongues 32 are formed.
• the inside diameter of the sleeve 28 essentially corresponds to the inside diameter of the opening 24.
• the post 4 is fastened to the device 2 in such a way that the fastening device 6 is first anchored in the ground, for example by screwing in or concreting in.
• the support plate 16 is placed on the underside or end face 14 of the post 4 and connected to the end face 14.
• the fastening projections 18 are provided on the support plate 16, which protrude into the material of the post 4 when one or more hammer blows are applied to the support plate 16.
• the post according to FIG. 1 is placed on the fastening device 6 from above.
• the post 4 is then tilted, preferably with the aid of a plumb bob or a spirit level, in such a way that any inclined positions of the fastening device 6 are compensated for and the post 4 is exactly vertical.
• This tilting of the post 4 relative to the fastening device 6 is made possible by the fact that the outer diameter of the holding mandrel 10 is significantly smaller than the inner diameter of the bore 12, so that the mandrel 10 can run obliquely or obliquely in the interior of the bore 12.
• the upper free end of the holding mandrel 10 digs into a base 34 of the mounting hole 12, so that the post 4 is securely fixed in two points, namely once in the area of the sleeve 28 and once in the area of the base 34 of the mounting hole 12 As a result, the post 4 is held relative to the fastening device 6.
• the position fixing of the post 4 relative to the fastening device 6 can be regarded as practically immovable due to the high clamping forces between the sleeve 28 and the post 4, which are generated by the radial expansion of the sleeve 28.
• This non-positive and / or positive connection of the sleeve 28 to the holding mandrel 10 or the support plate 16 can be reinforced by the fact that the holding mandrel 10 also penetrates the opening 24 in a non-positive and / or positive manner by the maximum effective outer diameter of the holding mandrel 10 is made somewhat larger than the inner diameter of the opening 24.
• the cross section of the opening 24 depends essentially on the cross section of the holding mandrel 10. This means that if the holding mandrel 10 is tubular with a circular cross section, the opening 24 also preferably has a round cross section, as shown in FIG. 2. However, the opening 24 can equally well see square or have a polygonal cross section.
• a polygonal, i.e. polygonal cross section of the opening 24 can also be used with a round cross section of the holding mandrel 10.
• the forces required on the post 4 to fasten it to the fastening device 6 are limited to those forces which are necessary to attach the post 4 to the holding mandrel 10, which passes through the opening 24, which is preferably made with undersize, and the forces necessary for pressing or driving the mandrel 10 into the base surface 26 and for expanding the sleeve 28.
• the risk that the fastening device 6 can loosen due to the forces applied to the post 4 when it is fastened in the ground is thus considerably reduced.
• the radially widening sleeve 28, which rests under high pressure on the inner circumference of the receiving bore 12, allows very high and, in particular, permanent holding forces to be obtained, so that the post 4 can be reliably fixed in position.
