Description

Field of the invention

The invention relates to the shaft frame of conveyors.

State of the art

Elevator systems, in particular platform lifts for the disabled or lifts for goods transport, are often erected with a prefabricated shaft scaffolding.

This can be mounted as a load-bearing or self-supporting shaft scaffolding indoors or outdoors. The load-bearing shaft framework construction consists of posts and crossbars in the form of scaffold profiles, in particular hollow steel profiles. In order to create a barrier that is closed at least over the travel path, shaft scaffolds are often lined with glass, facade panels or other material. The shaft framework serves - in addition to the static function and the inclusion of the shaft lining - also the guidance of the lifting device. The load-carrying means can be moved via a predefined path, the so-called delivery height. The load-receiving means may be an elevator car or just an elevator platform.

The main components of the guide of the load-carrying means include the guide rails, which are in the area between the load-carrying means and the inner boundary of the shaft - fixed in the concrete case on the shaft frame. At least one guide rail, but normally two, is required to guide the load handling device. As guide rails i. d. R. steel rails used in the form of T-profiles.

The guide rails may be arranged in a plan view orthogonal or parallel or at any other angle to the plane of the access side. The local orientation to the center of the earth can be vertical, horizontal or at any other angle.

The guide of the load-receiving means on the guide rails can be configured as a sliding guide or roller guide. In this case, the moving part of the elevator system, the load-carrying means, equipped with at least two guide shoes, which are mounted on the chassis of the load-carrying device.

In a sliding guide of the lifting device, the guide shoes are often equipped with a special plastic insert, which in combination with an oil lubrication helps reduce the friction of the guide shoes on the guide rail. In a roller guide, the guide shoes usually consist of stored plastic rollers that run along the guide rail. The load-carrying means can be electrically, for. B. with a rope, chain or with a spindle drive, or hydraulically, for. B. with a hydraulic ram are driven.

For mounting a conventional shaft scaffold posts and bars i. d. R. consuming bolted together. For this purpose, holes are made in posts and bars, which are tailored to the requirements of a specific installation situation -. As the floor spacings and the delivery height, are tuned or the items are welded together. For the assembly and alignment of the guide rails in conventional conveyor systems, a separate rail fastening system is required. This leads to an increased technical complexity, which has an effect on the manufacturing costs and in particular on the assembly times. The rail fastening system must be aligned by hand and also requires additional installation space. A space-saving installation variant is thus made more difficult. If the chess frame for security reasons i. d. R. obtained required all-sided shaft defense, the shaft framework is costly disguised after completion of the assembly work.

Object of the invention

The object of the invention is to provide a scaffolding system that is made largely independent of the local installation situation and allows a much simplified installation on site.

solution

This object is achieved by the invention with the features of the independent claim. Advantageous developments of the invention are characterized in the subclaims. The wording of all claims is hereby incorporated by reference into the content of this specification. The invention also includes all reasonable and in particular all mentioned combinations of independent and / or dependent claims.

To solve the problem scaffold posts with integrated grooves - a groove is an elongated recess in manufacturing technology - for guide rail, further grooves for simplified attachment of the crossbar and grooves for a standardized recording system for a variety of possible scaffold panels with the matching crossbars.

It is proposed an execution of the post according to the following description.

The post has a longitudinal axis and a wall. Formed on the post is a first groove for receiving a guide rail, the first groove being parallel to the longitudinal axis of the post, and the first groove projecting outwardly from the wall of the post. In this case, the first groove is open to the outside and accessible from the outside for receiving the guide rail.

Furthermore, two second grooves for fixing crossbars to the post are formed on the post, the two second grooves being parallel to the longitudinal axis of the post, and being disposed on both sides of the first groove on the post. The two second grooves are formed projecting from the wall of the post inwardly and opened to the outside. To attach the crossbar, the two second grooves are accessible from the outside.

Advantageously, two third grooves for attachment of a panel are formed on the post, wherein each second groove assigned to a third groove and disposed on the side facing away from the first groove side of the respective second groove.

The two third grooves are parallel to the longitudinal axis of the post, the two third grooves are open to the outside and are accessible for attaching the panel from the outside.

It is advantageous that the post is integrally formed with all the grooves.

The post can be mounted vertically, horizontally or at any other angle. Here is the post ( 101 ) integral part of a shaft framework or it can be mounted independently. As cladding glass plates, wall panels, facade panels o. Ä. Can be used.

The post can also be made in an advantageous embodiment of an extruded aluminum hollow profile.

A further advantageous embodiment is characterized in that a steel guide rail is inserted during the extrusion process in the first groove and forms a unit with the framework post.

It is also possible that instead of the first groove for receiving a guide rail, this guide rail is formed integrally with the post.

Already during the extrusion process, a guide rail made of aluminum can be formed. Should it be necessary z. B. for this purpose high-strength aluminum can be used or a higher strength can be achieved by anodizing or other surface treatment process.

Another advantageous embodiment of the post can also be characterized in that a guide rail made of steel is glued into the first groove. In this embodiment, the guide rail is already glued on the production side with composite adhesive after the extrusion process, so that no further screwing is required.

The invention also includes a shaft framework for a conveyor system with a load-receiving means, which has at least one post of the type described above and at least one cross bar. In this case, two fourth grooves for receiving a cladding are formed on the cross bar on opposite sides and these fourth grooves are in shape match with the third grooves of the scaffold post.

The matching to the scaffold posts crossbar allow in conjunction with the scaffolding posts the formation of a well-line-mounted shaft lining. If the system for fixing the manhole cover in the scaffold post is eliminated, thus allow the cross bar to form a two-sided horizontally mounted manhole cover.

The shaft frame thus represents a modular system, which has the possibility of uncomplicated installation of an easily installable panel. Cladding elements, such. B. glass can be used in commercial seals. The proposed solution represents an easy-to-assemble, modular, wind- and weather-protected shaft framework for elevator systems.

In this case, the shaft framework z. B. have a square outline. The shaft framework, consisting of the scaffold posts and the crossbars, can be designed such that it can be used as a supporting structure that supports the shaft reinforcement and other loads such. B. receives the drive for the movable elevator platform is configured. The shaft frame of the elevator system, which is suitable for the transport of persons and / or goods, can generally be used both indoors and outdoors.

Although the scaffold posts and crossbars are preferably made of extruded aluminum hollow sections, are also solid profiles, which can be produced on different types of production, conceivable. For reasons of weight and cost, however, extruded hollow profiles are to be preferred. The extrusion process allows the design of complicated geometries according to customer specifications by making a special tool. In the profile thus the required number of grooves can be incorporated, which allow the inclusion of guide rails, cross sections and manhole covers. Further advantages of this design are the low weight - the stability of the system is achieved by a suitably designed profile geometry - and the corrosion resistance, which allows a permanent outdoor use.

Guide rails and scaffold posts can be manufactured in different standard lengths, preferably lengths of 6 m are easy to handle and easy to handle. For higher shaft stands, the scaffold posts can be easily extended (extended) via plug connectors.

At least two (eg diagonally opposite) scaffold posts of the shaft framework are provided with guide rails.

The guide rails may consist of machined flat steel, the z. B. as unalloyed structural steel in lengths between about 3 to 13 m with standardized nominal widths and nominal thicknesses is commercially available. The guide rails can be designed with a nominal width of approx. 100 mm and a nominal thickness of approx. 10 mm. Other flat steels known to the person skilled in the art, but also other suitable metallic and non-metallic materials, which in particular meet the requirements for material properties for guide rails in elevator systems, can be used in the proposed solution.

It is favorable that the guide rails can be inserted into the groove provided in the framework post. Alignment during assembly is not required if both the groove in the framework post and the guide rails are made sufficiently accurate. The fastening of the guide rails via a screw connection. In the framework profiles and the guide rails for this purpose corresponding through holes are present, which are preferably lasered out. The mounting of the guide rails is preferably already in the manufacturing plant. The guide rails must therefore no longer be installed and aligned on site. As a result, no additional structures on the shaft framework are required, which require additional space. In particular, in a space-saving diagonal arrangement of the guide rails, the attachment and alignment of these structures is connected on site with greater effort.

The compact design of the chess frame is favorable for the optimal spatial utilization when installing an elevator system in buildings.

The attachment of the crossbar is preferably on preassembled fittings.

The fittings are already on the required distances, z. As the floor distances, pre-assembled on the inside T-slot. If the distances later do not match the structural requirements, the crossbars can be easily moved on site by loosening the screw. The fittings are bolted with a slot nut in the T-slot. The slot nuts can be inserted into the T-slot on the face side and ensure a stable connection as soon as the fastening screw of the connection piece is tightened. The crossbars have on the bottom or the top of a recess, which allows the cross bar to slide from below or from above the fittings. Also, the crossbars can simply be pushed vertically over the connector, this should allow the local installation situation. A recess on the crossbar can then be omitted. Thereafter, the crossbars are bolted to the fittings. For this i. d. R. 2 screws per crossbar sufficient.

The scaffolding cladding is installed via a clamping connection between the shaft-side stop edge and the storey-side terminal strip. Various dry seals are available on the open market for the terminal strip, as well as for the bay-side stop edge. This system is designed in the framework posts as well as in the crossbars, so that it is possible to realize a scaffold cladding supported on all sides in a linear manner. Alternatively, 2-sided vertically or horizontally mounted scaffold panels executable when dispensed either in the post or the crossbars on the holding system.

Further details and features will become apparent from the following description of preferred embodiments in conjunction with the subclaims. In this case, the respective features can be implemented on their own or in combination with one another. The possibilities to solve the problem are not limited to the embodiments. For example, area information always includes all - not mentioned - intermediate values and all imaginable subintervals.
