Description

Description: The invention relates to a device for releasably fastening at least one parapet or scaffold console, with at least one first receiving element for receiving a first holding, supporting and / or clamping element of the parapet or scaffold console and at least one second receiving element for receiving a second Holding, supporting and / or clamping element of the parapet or scaffold console and at least one anchor element that can be concreted and anchored in a building, the first receiving element and the first anchor element being firmly connected to one another, and at least one insulating or formwork element being permanently connected to at least one receiving element is.

From WO 93/20308 A1 a device for releasably holding form panels, formwork boards, insulation and facade panels, parapet poles, scaffold consoles and the like is known, which has concretable and anchored L-shaped holding parts in the building. Each of these holding parts comprises a plurality of receptacles, in which corresponding areas of holding, supporting and / or clamping elements of parapets and / or scaffolding consoles or the like can be releasably inserted. First receptacles with a substantially vertical receptacle axis and second receptacles with a substantially horizontal receptacle axis are provided. Each first receptacle is formed by an upwardly open square tube of the holding part, into which a square-shaped plug part of a plug yoke can be inserted in the vertical direction. The second receptacle is formed by a lateral opening in the holding part, into which an adapter element for a holding, supporting and / or clamping element with its insertion area can be inserted. The adapter element has at its end facing away from the opening a square tube open at the top, into which a holding, supporting and / or clamping element of a parapet or a scaffold console can be inserted. The holding part also has grooves for releasably receiving insulation or holding and / or formwork panels.

From DE 295 04 806 U1 a holding device for releasably attaching formwork panels, formwork boards, facade and insulation panels, parapet poles, scaffolding consoles and the like is known, which has an L-shaped angle element with a first leg and a second leg, wherein the essentially horizontal first leg is designed to rest on and be fastened to a wall crown, a ceiling formwork or a filigree or prefabricated panel, and the essentially vertical second leg is provided to receive a holding, supporting or clamping element. Formwork boards can also be releasably attached to the holding device.

The CH 678081 A5 discloses a device for releasably attaching a parapet to the lateral ends of buildings, such as concrete ceilings, which have a one-part or multi-part, substantially L-shaped support element with at least one plug leg, and at least one arranged in or on the side end Includes plug-in receptacle with which the plug leg can enter into a releasable plug connection. The plug-in part is arranged horizontally and is intended for concreting in a building part. Support rods with brackets for barrier boards are arranged on the support element.

The known devices have the disadvantage that the exact positioning of the holding parts for a parapet or a scaffold console and the formwork elements, as well as the removal of the formwork elements takes a relatively long time, which increases the construction effort and thus the construction costs.

The object of the invention is to avoid these disadvantages and to reduce the time and cost involved in securing and formwork work on buildings.

According to the invention this is achieved in that the device is constructed in a modular manner and consists of at least two modules which are firmly connected to one another, each module having at least one receiving element and at least one insulating or formwork element,

Patent Office and wherein at least one insulating or formwork element is permanently connected to at least one receiving element.

The connection between the insulating or formwork element and the first and / or second receiving element can be made by screwing, riveting, welding and / or gluing.

The insulating or formwork element and at least one receiving element can thus be processed as a prefabricated part in one piece, whereby the assembly and positioning effort can be reduced. The connection and assembly of the insulation and formwork element with the receiving element can be done in advance in the factory, which minimizes the workload at the construction site. To make transportation easier, it is also possible to combine the individual prefabricated parts into one unit only at the construction site - before concreting.

It when the insulating or formwork element is designed as lost formwork is particularly advantageous. A lost formwork is a formwork that cannot or cannot be removed after the concrete has been concreted and hardened. If the formwork is lost, the time required to remove the formwork after the concrete has hardened is eliminated.

A particularly advantageous embodiment of the invention provides that the formwork element and / or insulating element is formed in one piece with at least one first receiving element, preferably in one piece with a plurality of first receiving elements. In particular, it can be provided according to an embodiment variant of the invention that at least one first receiving element is formed by the insulating or formwork element, preferably by a protrusion of the insulating and formwork element. An overhang in this case is an area of the insulating and formwork element that projects upward from the concrete ceiling essentially vertically when installed, ie concreted in. This projection can be provided with mounting holes for fastening screws or rivets for receiving first holding, supporting and / or clamping elements for a parapet or scaffold console or for a structural part.

Alternatively or additionally, it can be provided in a continuation of the invention that at least a first receiving element is formed by a profile tube or a profile bar or a flat bar or a plate. Profile tubes or profile bars in particular are particularly advantageous for positively receiving correspondingly reciprocally shaped holding, supporting and / or clamping elements of parapets or the like by pushing them into or over the profile tubes or profile bars. The profile tubes or profile bars can, for example, have a rectangular cross section. Of course, other cross sections, such as circular cross sections, hexagonal cross sections or the like, are also possible.

Conveniently, at least one first receiving element has at least one guide edge or guide surface which defines a first receiving axis for receiving the first holding, supporting and / or clamping element, the first receiving axis preferably being configured substantially vertically in the installed state. The first holding, supporting and / or clamping element is mounted and received essentially in a direction parallel to the first receiving axis.

The formwork or insulating elements form, together with the first and second receiving elements, a self-supporting structure, so that positioning before concreting is made considerably easier. In order to improve the self-supporting function, it is advantageous if the insulating or formwork element has individual segments, wherein a longitudinal stiffening, preferably made of flat steel or a profile tube, or the first receiving element is arranged between two adjacent segments, preferably parallel to the first receiving axis.

An advantageous embodiment of the invention provides that the second receiving element is formed by a sleeve, preferably a threaded sleeve, advantageously the

Patent Office

Sleeve - when installed - is aligned horizontally. Holding, supporting and / or clamping elements with a reciprocal external thread corresponding to the internal thread can be screwed into the threaded sleeve having an internal thread and thus releasably connected to the holding part.

The second receiving element is arranged, for example, normal to the first receiving element.

A simple manufacture results if at least one first anchor element is formed in one piece with at least one second receiving element, the first anchor element preferably being formed by a deformed region of the second receiving element.

The second receiving element has at least one guide edge or guide surface, which defines a second receiving axis for receiving the second holding, supporting and / or clamping element, wherein the second receiving axis is preferably formed substantially horizontally in the installed state.

The assembly and reception of the second holding, supporting and / or clamping element takes place essentially in one direction parallel to the second receiving axis.

In a further embodiment of the invention it is provided that the device has at least a second anchor element, wherein the second anchor element is preferably formed by a tension element, particularly preferably made of structural steel. This design has the advantage that insulating or formwork elements with a relatively large height can be used and that the device can be fixed in a particularly stable manner in the hardened concrete.

It when the insulating or formwork element has at least two segments, wherein the segments are arranged on both sides of a first receiving element is particularly advantageous. As a result, the connection between two adjacent modules along adjoining segments of the insulation and formwork elements of the two modules can be established, for example by screwing, riveting, gluing or welding.

The invention is explained in more detail below with reference to the non-restrictive exemplary embodiments shown in the figures.

At least two first receiving axes 3a span a first plane 3b, which - in the installed state - is arranged essentially vertically. At least two second receiving axes 4a span a second plane 4b, which is arranged essentially horizontally in the installed state. Thus, a receptacle for a substantially vertically oriented parapet 20 can be formed with the first receptacle elements 3 and a receptacle for a horizontally aligned scaffold bracket 21 with the second receptacle elements 4. In all versions, the first receiving element 3 can also protrude beyond the concrete ceiling 15 if necessary.

Furthermore, the holding part 2 has a first anchor element 5, which serves to form an indissoluble bond with the hardened concrete, for example the ceiling 15. In the embodiment variants shown, the second receiving element 4 is in each case made in one piece with the first anchor element 5.
