t for shuttering), walls to be concreted

The invention relates to a climbing frame for shuttering walls to be concreted, with one on the already concreted Part of the wall to be releasably attached frame, which has an upper working platform, over the one The formwork panel can be swiveled and can be reset from the working position »

Climbing frames are used to erect tall structures such as Transmission towers, cooling towers, bridge piers and the like used. For shuttering, the climbing scaffold is first attached to the already completed uppermost part of the concrete

building by means of anchoring elements provided there detachably attached. Are the reinforcement work of the to the next part or section of the structure to be concreted is finished, the one above the top working platform

It is known to arrange the formwork panel aiif a chassis' ^ which, on parallel beams of the upper ^; . Working platform supported by the frame «Here, the load of the formwork panel rests on the girders of the upper working platform, which are at different positions depending on the position of the formwork panel. A further disadvantage is that the pressure of the freshly poured concrete tends to push the formwork panel away from the wall, so that the record or its chassis is very carefully in the operating position must be locked

The invention is based on the object of an improved To create a climbing frame for shuttering walls to be concreted, in which the shuttering panel does not have any. '. . .. exerts bending moments on the frame and in the operating position with their weight against the concreting

! This object is achieved according to the invention in that; the formwork panel rests on supports that are pivotably mounted on the frame and are approximately vertical. This way '_

will and accordingly overcome a dead center, which is located between its operating position and the reset position, so that the weight of the ^: shell plate acts both in the operating position and in the reset position in the extreme position that can be reached, so that the shell plate pressed with its weight in the operating position against the wall section to be concreted. Accordingly, the panel does not need to be secured as firmly as before in the operating position, because its weight counteracts the pressure of the fresh concrete. In the reset position, the formwork panel does not need to be locked because it does not inadvertently move from this position into the operating position, v: ie this could be the case when it is supported on a chassis.

The supports carrying the formwork panel are preferably hinged below the upper working platform on the frame, so that the support of the formwork panel in the area or

; near the center of gravity of the frame. .

In addition, the supports can be attached to horizontal

can be that slidably sits on a carrier. This slide can be mounted on a support of the upper working platform sit * In this embodiment of the invention the support is also connected to a horizontally adjustable slide, the one additional Forms a support so that the formwork panel does not tip over during the adjustment test. “The slide also serves as an adjusting element for the formwork panel »

The formwork panel is preferably mounted on the supports in a height-adjustable manner in order to compensate for or avoid inclinations.

To adjust the slide, according to a further feature of the invention, it is provided with at least one detent and preferably provided with a plurality of notches into which a lever mounted pivotably on the frame can be engaged is. In addition, the slide can be stranded with a footrest. For adjusting the slide and with it the shuttering plate, the lever is engaged in a detent and then pivoted, whereby the slide is displaced on the relevant support of the frame. The foot ~ detent is expediently designed so that it has to be actuated to release and fixes itself when it does not is operated. Needs to move the lever to another detent or to stop the slide at all the operator just let go of the footrest, whereby it takes effect immediately and stops the carriage. If the .Schlitten is to be moved wider, you only have to step on the footrest again.
