Description

Attachment for a formwork and formwork with an attachment

The invention relates to an attachment in the form of a heating cassette for heating a frame panel formwork element, wherein the heating cassette is reversibly releasably connectable to the frame panel formwork element and has a heating device for heat generation.

The invention further relates to a formwork with a

Frame panel formwork element and such an attachment.

It is known, heated formwork for casting a body of in-situ concrete, for example, for casting a concrete wall or a

Concrete column, use. The heated formwork allows the production of a body of in-situ concrete at low temperatures, especially in frost.

For example, it is known from DD 32 711 A3, a heatable formwork element with an electrically heatable

Steam generating chamber for shuttering one to be produced Use concrete wall. The steam generating chamber is integrated into the shell element, ie, inseparably connected to the shell element. As a result, it is not possible to use the formwork element in warm weather without the steam generating chamber.

Furthermore, DE 196 04 835 AI discloses a device for sealing duct walls. The device comprises an elastically expandable casing on which electric radiant heaters are arranged. The radiant heaters may be in the form of incandescent lamps. A disadvantage of this device, however, is that it must always be used together with the electric radiant heaters or transported and constructed.

From DE 2 061 394 A is a formwork for use in the

Processing of in-situ concrete has become known. The formwork comprises a formwork element with incorporated in the shell

Resistance heating. The resistance heating wires must also be transported and set up with the formwork element during operation in warm weather.

CA 1 158 119 A discloses a portable heater for heating freshly cast bodies of in-situ concrete. In this case, a liquid is heated in the heater and guided in flexible tubes around the body. The heating of a formwork has not become known from CA 1 158 119 A.

Finally, it is known from JP 2008095434 A to arrange an electric heater on a steel formwork by means of a magnetic connection reversibly detachable. The steel formwork is thus in the

Warm-weather operation can also be used without the electric heater. Due to the completely plate-shaped design of the heater and the flat magnetic connection of the known heater is relatively heavy, whereby the heater is expensive to transport. Furthermore, the magnetic connection between heater and steel formwork is difficult to solve.

In contrast, the invention is based on the problem of enabling the casting of a body of cast-in-situ concrete, both at high and at low outside temperatures, while at the same time allowing easy transport and easy handling of formwork.

Object of the present invention is therefore to provide a heating cassette, which is both easy to transport and easy to mount on a frame panel formwork element or dismountable from this.

This object is achieved by a heating cassette with the features of claim 1. The dependent claims indicate expedient developments.

The object of the invention is thus achieved by a heating cassette for heating a frame panel formwork element, wherein the heating cassette is reversibly releasably connectable to the frame panel formwork element and has a heating device for heat generation and wherein the

Heating cassette has a first part of a mechanical connection means for mounting the heating cassette on the frame panel formwork element.

According to the invention, the heating cassette is accordingly by means of a

mechanical connection device reversibly detachable with the

Frame panel scarf element connectable. The heating cassette has a first part of the mechanical connection device and the

Frame panel sheath a second part of the mechanical

Connection device on. Preference is given here as the second part of mechanical connection means used an element that already exists on the frame panel shell anyway. Thus, an already existing Rahmenafelschaleiement be retrofitted with a heating cassette.

The mechanical connection device is preferably not based on a magnetic connection. The mechanical connection device is designed in particular non-magnetic.

The mechanical connection device can be designed in the form of a tongue and groove connection. Furthermore, the mechanical connection device in the form of a hook-eye connection

be educated. The first part of the mechanical connection device can be designed in the form of a first projection, which engages behind a second part of the mechanical connection device in the form of a second projection. The mechanical connection device allows a quick and easy installation of the heating cassette on the frame panel sheath and a quick and easy disassembly of the heating cassette from the frame panel sheath. At the same time, the mechanical connection device leads to a continuous and reliable connection between the heating cassette and

Rahmentafelschaleiement. At high outside temperatures can be dispensed with the installation of the heating cassette. Transport and installation of the heating cassette thus actually fall only in the case of low

Temperatures or frost.
