Definitions
- the invention relates to a lifting platform, in particular for motor vehicles according to the preamble of claim 1 and a method for producing the lifting platform.
- Lifting platforms have so far been provided with supporting columns, which are produced, for example, by welding correspondingly strong steel sheets together.
- a support column In order to meet the high requirements of a lifting platform, for example for lifting motor vehicles, such a support column must have a certain stability. This is achieved either by using a large amount of material or by appropriate shaping. Even with a corresponding profiling of the support column, there is a corresponding effort in production, in particular when welding the steel sheets or profiles. In addition, a large amount of material is still required.
- the object of the invention is therefore to propose a lifting platform that enables production with greatly reduced effort and thus reduced costs.
- this object is achieved by the characterizing features of claim 1.
- a lifting platform according to the invention with a support column which comprises a shaped body which consists at least partially of flowable, curable material.
- cross sections can be circular, oval, star-shaped or as any polygon.
- a lift with a support column can be made, which consists essentially of concrete.
- Flowable materials such as concrete or concrete combined with special aggregates, can be considerably cheaper than the relatively thick-walled steel used up to now.
- the flowable material can be processed, for example, by pouring, spinning or extruding. Concrete in particular can be processed using this method.
- a waterproof special concrete is preferably used as the material for casting the support column.
- special concrete that is not only waterproof but also hardens with a slippery and structurable surface.
- the support column can be used without additional coating on the outside.
- a colored concrete is used.
- an envelope is also used which at least partially forms the outside of the support column and is filled with the curable, pourable material.
- This cover can on the one hand have a positive influence on the appearance of the support column, and on the other hand the technical properties, for example the sliding ability of the surface, can be improved accordingly.
- Guide means for a lifting device which are essentially parallel to the axis are preferably integrated into a support column of a lifting platform according to the invention.
- the support column can easily be provided with a lifting unit by such guide means.
- the guide means advantageously comprise at least one guide groove formed in the support column. Corresponding sliding or rolling elements of a lifting unit can be reliably guided in such a guide groove along the axis of the support column.
- the shell can be assembled from sections. This makes it possible, for example, to manufacture the cover from a less expensive material in an area that is not visible depending on the area of use or the shape of the support column. Furthermore, a composite shell made of different Materials also bring about desired optical effects on the surface of a support column according to the invention. Depending on the shape of the support column, the manufacture of a casing according to the invention is also considerably simplified by assembling it from different sections.
- a support column according to the invention can be covered with a covering material for various reasons.
- the covering material can be applied, for example, for reasons of the optical impression or also to improve the surface properties, for example the sliding properties, etc.
- Such covering material can for example be glued and / or jammed or attached in some other way.
- the sleeve is at least partially made of a preformed, dimensionally stable material.
- This embodiment variant has the advantage in production that no external shaping tools are required after the casing has been finished.
- the inherently stable shell preferably made of a metal sheet of appropriate wall thickness and possibly with corresponding stiffening elements, only needs to be filled with the filling material, for example concrete, after its completion, which increases the rigidity of the support column thus formed.
- an extruded profile is used for the outer wall of the support column.
- Such an extruded profile for example made of anodized aluminum, offers the advantage of inexpensive production with a large selection of shapes for the profile cross section.
- This manufacturing process can be further developed by dividing the entire support column in the longitudinal direction into individual extruded profiles, which are only assembled and cast during the manufacture of the support column.
- Such individual segments of a sheath separated in the longitudinal and / or transverse direction, in particular in the form of individual extruded profiles, are connected in a particularly advantageous embodiment with the aid of latching means for connecting individual segments.
- latching or snap closures can be molded into the individual segments, for example, during extrusion and make production considerably easier.
- additional sealing means are provided for individual filling areas of the support column to be filled with filling material. This is particularly advantageous if the inner or outer shell of the support column is interrupted for manufacturing reasons, which can be the case, for example, when using multiple extruded profiles.
- the envelope that at least partially forms the outside of the support column is at least partially formed by a film that is not independently dimensionally stable.
- the filling material is of even greater importance for the rigidity and thus the resilience of the support column than in the aforementioned exemplary embodiment.
- the cost of materials or the cost of procuring the necessary material is reduced enormously in this exemplary embodiment.
- the casing of the support column is arranged in a manufacturing mold and is designed such that it is at least partially deformable when filled with the hardenable filling material and / or the hardening of the filling material to form a positive fit with the manufacturing mold.
- the deformable casing is first introduced into the mold and then the curable filler material is poured in.
- the filler material presses the casing against the inner wall of the mold in a form-fitting manner, so that there is a smooth outer wall of the molded body in the region of the casing.
- the stability of the molded body is ensured by the filler material after the filler material has hardened.
- This support column can be shaped with any design and still fulfill a supporting function due to the shape or the choice of material. Due to the prefabrication in a corresponding shape, almost any shape can be created for a support column. In addition, the outer skin protects the corresponding support column from corrosion, since the penetration of moisture is prevented.
- a sliding surface that can be used, for example, for guiding a lifting truck for the lifting platform can be realized by a casing of a molded body according to the invention.
- the filling of curable filling material is additionally z. B. by shaking or pumping condensed. This increases the shape accuracy, stability and load capacity of the support column.
- a prestressed reinforcement is preferably provided for a support column.
- a prestressed concrete molded body results, if necessary, with an outer skin such as the above.
- Such reinforcements possibly in conjunction with a bracing, can significantly increase the stability and resilience as well as the material utilization of the molded body, which enables more cost-effective production.
- the prestressed reinforcement parts can be, for example, in the form of tension rods, tension wires or tension cables, e.g. B. made of steel or the like.
- the prestress offers the advantage known from prestressed concrete, particularly in the case of concrete, that it remains permanently stable and does not crack.
- Clamping elements only introduced after pouring and hardening of the filling material. Suitable openings are provided for this. These passages can be present, for example, in an extruded profile in the form of through-tubes.
- the column is placed on a base plate, which is connected to the clamping elements.
- tie rods can be screwed to the base plate or anchored in some other way.
- the support column can then be clamped by attaching a cover plate and tightening with the aid of the tensioning elements passing through the support column.
- the edge elements are connected to the molded body with the aid of such reinforcement parts.
- the connection of the edge elements for example pasture of a base or cover plate, can in this case, for example through continuous reinforcement parts as mentioned above.
- a base plate is provided as the edge element, which can be fastened to the floor or the foundation of a building.
- the insert parts for stabilization for example reinforcing steel, are designed to be continuous, since this greatly improves the load-bearing capacity of the support column.
- the outer skin of the molded body is designed as a slidable surface and at the same time a sliding guide, for example in the form of a guide groove, is molded into the support column during manufacture.
- a lifting unit for example in the form of a lifting truck, is preferably arranged inside such a guide groove.
- This pallet truck is preferably mounted on the groove wall by means of additional sliding elements and is height-adjustable by means of a drive unit, for example a spindle drive.
- the drive spindle also preferably finds space inside the guide groove formed in the support column.
- the shell is entirely or partially preferably in the form of a film or sheet made of steel, in particular stainless steel.
- a smooth steel surface can be slidably mounted on a pallet truck.
- outer shells it would also be conceivable for outer shells to be made entirely or partially from other materials, e.g. B. are made of aluminum, gold, platinum, titanium, etc.
- a manufacturing mold is used to manufacture the support column according to the invention, which comprises a shrinkable molding compound.
- a casting resin that has a certain temperature expansion comes into question. If such a temperature-dependent molding compound is heated and then cooled during production, such a production mold can be more easily released due to the shrinkage during cooling.
- the manufacturing mold is provided with a tensionable outer wall. It would be conceivable, for example, to provide a metal outer wall adjoining the shrinkable molding compound with a small clamping gap, which is advantageously also incorporated into the molding compound. By contracting this gap, the outer wall of the manufacturing mold is then clamped.
- an inner mold core is preferably provided, for example in the form of a tube.

- it allows heating means to be introduced into the interior of the production mold.
- heating elements in connection with media guides come into question here.
- a separating layer is provided between the molding compound in different filling areas. A certain shrinkage behavior during cooling can be achieved with this.

- Such a clamping bracket advantageously has a vertical section, for example in the form of a support tube, which is inserted into the interior of the support column to be manufactured. This vertical section is supported on the base plate of the support column to be manufactured. Corresponding fastening elements for tensioning the reinforcement parts are provided on the top of the vertical section. Fastening elements of this type are provided in a simple exemplary embodiment by a horizontal flange which has circumferential bores for receiving the reinforcement parts, for example the reinforcement rods, cables or wires.
