The invention relates to a device for releasably attaching at least one parapet or a scaffolding bracket, with at least one first receiving element for receiving a first holding, supporting and / or clamping element of the parapet or scaffold bracket and at least one second receiving element for receiving a second support, support - And / or clamping element of the parapet or scaffold bracket and at least one einbetonierbares in a building and anchorable first anchoring element, wherein the first receiving element and the first anchor element are firmly connected to each other, and wherein at least one insulating or shuttering element is firmly connected to at least one receiving element.

From the WO 93/20308 A1 a device for releasably retaining formwork panels, shuttering boards, insulation and facade panels, parapet rods, scaffolding brackets and the like is known, which in the building einbetonierbare and anchored L-shaped holding parts. Each of these holding parts comprises a plurality of receptacles in which corresponding areas of holding support and / or clamping elements of parapets and / or scaffolding brackets or the like are releasably insertable. In this case, first images are provided with a substantially vertical recording axis and second images with a substantially horizontal recording axis. Each first receptacle is formed by an upwardly open square tube of the holding part, in which a square shaped plug-in part of a plug-in yoke can be inserted in the vertical direction. The second receptacle is formed by a lateral opening in the holding part, in which an adapter element for a holding support and / or clamping element can be inserted with its insertion region. The adapter element has an end facing away from the opening an upwardly open square tube, in which a holding, supporting and / or clamping element of a parapet or a scaffold bracket can be inserted. The holding part further has grooves for releasably receiving insulating, or retaining and / or shuttering panels.

From the DE 295 04 806 U1 For example, a fixture for releasably securing formwork panels, shuttering boards, facade and insulation panels, parapet poles, scaffold brackets, and the like is known, which includes an L-shaped angle member having a first leg and a second leg, with the substantially horizontal first leg being formed auflieiegen on a masonry crown, a slab formwork or a Filigran- or precast panel and to be attached and the substantially vertical second leg is provided to receive a holding support or clamping element. Here also shuttering boards can be releasably attached to the fixture.

The CH 678081 A5 discloses a device for releasably attaching a parapet to lateral ends of structures, such as concrete ceilings, which comprises a one- 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 socket receiving part, with which the plug leg can enter a re-releasable connector. The plug-in receiving part is arranged horizontally and is provided for setting in concrete in a building part. On the support element support rods are arranged with holders for Abschirmungsbretter.

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

The object of the invention is to avoid these disadvantages and to reduce the time and cost of safety and formwork of buildings.

According to the invention this is achieved in that the device is constructed like a module, and consists of at least two mutually firmly connected modules.

It is preferably provided that at least one insulating or shuttering element is permanently connected to at least one receiving element.

The connection between insulating or formwork element and the first and / or second receiving element can be done by screws, rivets, 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 joining and joining of the insulating and formwork element with the receiving element can already be done in advance in the factory, which minimizes the workload on the site. In order to facilitate the transport, it is also possible to assemble the individual prefabricated parts only on the construction site - before setting in concrete - into a single unit.

It is particularly advantageous if the insulating or shuttering element is designed as permanent formwork. A lost formwork is understood to mean a formwork that can not be removed or removed after concreting and curing the concrete. For lost formwork thus eliminates the time required to remove the formwork after curing of the concrete.

A particularly advantageous embodiment of the invention provides that the formwork element and / or insulating element is formed integrally with at least one first receiving element, preferably in one piece with a plurality of first receiving elements. In particular, according to an embodiment variant of the invention, it can be provided that at least one first receiving element is formed by the insulating or shuttering element, preferably by a projection of the insulating and shuttering element. As supernatant here in the installed, so concreted state upwards substantially vertically from the concrete ceiling outstanding region of the insulating and formwork element is referred to. This supernatant can be provided for receiving first support support and / or clamping elements for a parapet or scaffolding bracket or for a building part with mounting holes for fastening screws or rivets.

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

Conveniently, at least one first receiving element on at least one leading edge or guide surface, which defines a first receiving axis for receiving the first holding, supporting and / or clamping element, wherein preferably the first receiving axis in the installed state is formed substantially vertically. The mounting and receiving of the first holding, supporting and / or clamping element takes place substantially in a direction parallel to the first receiving axis.

The shuttering or insulating together with the first and second receiving elements form a self-supporting structure, so that the positioning before setting in concrete is substantially facilitated. To the self-supporting function too it is advantageous if the insulating or shuttering element has individual segments, wherein between two adjacent segments a preferably parallel to the first receiving axis aligned longitudinal reinforcement - for example, flat steel or a profile tube - or the first receiving element is arranged.

An advantageous embodiment of the invention provides that the second receiving element is formed by a sleeve, preferably a threaded sleeve, wherein advantageously the sleeve - in the installed state - is aligned horizontally. In the threaded sleeve having an internal thread holding, supporting and / or clamping elements can be screwed with a reciprocal external thread corresponding to the 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 production results when at least one first anchor element is formed integrally with at least one second receiving element, wherein preferably the first anchor element is 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 preferably the second receiving axis in the installed state is formed substantially horizontally. The mounting and receiving of the second holding, supporting and / or clamping element takes place substantially in a direction parallel to the second receiving axis.

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

In a particularly advantageous embodiment variant of the invention, it is provided that each module has at least one first receiving element, at least one second receiving element and at least one insulating or shuttering element. It when the insulating or shuttering element has at least two segments, wherein the segments are arranged on both sides of a first receiving element is particularly advantageous. This allows the connection between two adjacent modules along adjacent segments of the insulating and formwork elements of the two modules, for example by screws, rivets, gluing or welding, are produced.
