Definitions

• the invention relates to an elevator, in particular for connecting different floors in buildings according to the preamble of claim 1 and a method for its production.
• elevators including backpack elevators
• self-supporting scaffolding or supporting columns connected to the building which are manufactured, for example, by screwing together or welding correspondingly strong steel profiles.
• a scaffold or support column In order to meet the high requirements of such an elevator, such a scaffold or support column must have a certain stability. This is achieved through high material expenditure and appropriate shaping in connection with large assembly effort.
• the object of the invention is therefore to propose an elevator that enables production with greatly reduced effort and thus reduced costs.
• an elevator according to the invention is provided with a support column which comprises a shaped body which at least partially consists of flowable, curable material.
• cross sections can be circular, oval, star-shaped or as any polygon.
• an elevator can be produced with a support column 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, flowable 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 an elevator 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 casing made of different materials can 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, production is simplified an envelope according to the invention by assembling from different sections also considerably.
• 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 filler material and / or the hardening of the filler 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 elevator can be realized by a casing of a molded body according to the invention.
• the filling of curable filler material is hardened before curing, e.g. B. additionally compacted by shaking or pumping.
