Definitions
- the invention relates to a frame formwork element for forming a solidifiable building material, with a frame and a multi-layer formwork facing attached to the frame according to the preamble of claim 1.
- the invention also relates to a formwork system according to claim 12.
- Frame formwork elements are used as parts of formwork systems, in particular for the production of concrete components.
- the frame formwork elements are arranged in such a way that they form a mold into which a solidifiable building material, mostly a liquid concrete, is introduced for the production of a concrete component, for example a wall element. After the concrete has solidified, the frame formwork elements are usually removed.
- the frame formwork elements have a frame to which the formwork skin is attached.
- the frames of the frame formwork elements should be stable in order to be able to transfer the loads that occur when the formwork system is filled with solidifiable concrete.
- the frame should be sufficiently rigid to ensure high dimensional accuracy and avoid undesirable deformation.
- the structure of a surface of the concrete component facing the formwork skin is determined by the formwork skin attached to the frame.
- a front side of the formlining faces the concrete to be filled, that is, the front side of the formwork skin forms the surface in contact with the concrete, while the rear side of the formwork skin is attached to the frame.
- Damage to the front side of the formwork facing the concrete which can result, for example, from the transport or handling of the panel formwork element in construction site operation, is reflected accordingly on the visible surface of the concrete component to be produced from the concrete. Damage to the formlining must therefore be repaired, which is done, for example, by filling out minor damage or by implementing repair sheets in the case of larger-area damage.
- the formwork skin is structured in its surface as a result, which is undesirable when producing concrete components.
- Frame formwork elements made of wood are known from the prior art. These have the disadvantage that they swell due to penetrating moisture. In the event of heavy use, the protective impregnation layer is destroyed and the surface frays. Furthermore, nails that are hammered into the formwork element during use lead to damage to the veneer layer or the protective impregnation layer, so that water can penetrate at these points.
- Frame formwork elements made of plastic are also known from the prior art. These do not show any swelling behavior due to penetrating water when they are damaged, but like wooden panels they have to be repaired in a complex and manual manner if they have been damaged during use, in particular on the surface of the formwork facing the concrete.
- a frame formwork element of the generic type is known from DE 101 14 161 A1.
- the generic frame formwork element has a frame and a multilayer formwork skin attached to the frame. It is provided that the surface of the formwork facing or touching the concrete is formed by a formwork foil.
- DE 101 14 161 A1 is based on the idea of avoiding time-consuming repair and improvement work on the formwork facing for reuse by replacing a scratched or otherwise damaged surface of the formwork facing with a new formwork film.
- DE 101 14 161 A1 provides for the surface of the formwork facing facing the concrete to be coated with a new formwork sheet in order to reuse the frame formwork element.
- the framed formwork element known from DE 101 14 161 A1 is intended to have a formwork skin with a formwork film, which can be detached from the carrier system and exchanged without being destroyed.
- the formwork foil is supposed to form the actual contact surface with the concrete and is responsible for the surface structure and the surface quality of the concrete.
- the object of the present invention is therefore to improve the frame formwork elements known from the prior art for forming a solidifying building material, in particular to enable a repair if the surface of the formwork facing the building material is damaged, and to increase the static load-bearing capacity of the frame formwork element as much as possible to enhance.
- Another object of the present invention is to improve the formwork systems known from the prior art, in particular to simplify their repair and to improve the static load-bearing capacity as far as possible.
- the frame formwork element according to the invention for forming a solidifying building material has a frame and a multi-layer formwork skin attached to the frame.
- the formwork skin has a support plate and a rigid wear plate.
- the support plate is attached to the frame and the wear plate is releasably attached to the support plate.
- a front side of the wear plate facing away from the support plate is designed as a surface in contact with the building material.
- the support plate is attached to the frame in a tensile and shear-proof manner in such a way that the support plate statically supports the frame, the support plate being permanently or partially releasably connected to the frame.
- the formlining according to the invention has a support plate and a rigid wear plate results in several advantages.
- the inventor has recognized that a rigid wear plate can be detached from the support plate in a particularly simple and advantageous manner.
- the rigid wear plate thus forms a wear layer that can be changed if necessary.
- the wear plate the front of which is facing the building material to be consolidated and thus the structure of the surface, d. H. the visible surface, the building material, especially concrete, can be replaced quickly and easily if the wear plate is damaged. This measure can be carried out in particular if the front side of the wear plate facing the building material should be damaged. It is easier to replace the rigid wear plate than to coat the formlining with a new formwork foil. Furthermore, a rigid wear plate is more robust than a shuttering foil, which is particularly advantageous in daily use on the construction site.
- the feature that the wear plate is releasably attached to the support plate preferably also includes a conditionally releasable connection, i.e. H. if only the auxiliary joining parts have to be destroyed in order to detach the wear plate from the support plate.
- the frame of the frame formwork element is preferably made of metal, in particular iron or steel.
