Definitions

• Heat-insulating shuttering element in particular for producing the formwork of a floor slab of a building and method for producing such
• the invention relates to a thermally insulating shuttering element, in particular for the production of the formwork of a floor slab of a building.
• the invention further relates to a method for producing a bottom plate formwork of such formwork elements.
• thermally insulated floor panels by means of thermally insulating formwork elements is e.g. known from DE 101 03 470 AI.
• L-shaped edge elements are connected to a circumferential closed outer frame together and filled the remaining space with an insulating layer.
• a foil is placed on the trough-shaped formwork produced in this way in order to prevent cemented milk from getting into the joints of the insulating layer, and fix the edge elements on the outside by means of ballast filling.
• the pouring of the concrete in the trough-shaped, consisting of the insulating formwork elements formwork to form the bottom plate.
• edge elements are interconnected only in the circumferential direction via a groove / spring connection and can move laterally against each other, so that despite the ballast support the emergence of an uneven edge contour, for example when pouring the concrete into the tray formed by the formwork elements are not excluded can.
• the invention has for its object to provide heat-insulating formwork elements with which in particular a trough-shaped formwork for the production of the bottom plate of a building can be built, with an additional support, e.g. by a timber formwork or a gravel filling, can be omitted. Furthermore, a method for producing a floor slab formwork from such formwork elements is to be specified.
• the invention is based essentially on the idea to provide the top and / or bottom of the formwork elements with knob-shaped connecting elements which are arranged such that depressions are formed from adjacent connecting elements, in which in the intended use of the formwork element corresponding noppenformige connecting elements at least one Connecting plate (hereinafter referred to as cover plate) formed formwork element engage positively to connect adjacent formwork elements together.
• cover plate Connecting plate
• knob-shaped connecting elements have a substantially truncated pyramidal shape, wherein the individual truncated pyramids can be connected to one another in their lower region.
• the formwork elements according to the invention can each have a different outer Have shape. It has proved to be particularly useful for building tannenformiger formwork for the production of floor slabs, both plate-shaped formwork elements having on its top and bottom knob-shaped connecting elements (base plates) and plate-shaped formwork elements, the knob-shaped fasteners only on its top or bottom bear (cover plates), as well as angle-shaped edge elements to stockpile, which have at least one vertical and one horizontal leg, the latter being provided on top and / or bottom side with knob-shaped connecting elements.
• the edge elements may also be formed as deliberatelyeck- or êteckmaschine.
• the edge elements can not move laterally during pouring of the concrete to form the bottom plate of the corresponding building, since the cam-shaped connecting elements of the cover plate engage positively in the corresponding recesses of the base plates and the edge elements.
• the dimensions of the cover plates are selected such that they fill the entire space between the vertical limbs of the edge elements and thus cover the joints of adjacent lower formwork elements.
• the end faces of the edge elements can be positively connected to one another via corresponding projections and grooves such that e.g. a Schwalbenschwanzf ⁇ hrung or a flat guide or the like. results.

• Fig. 1 denotes a thermally insulating formwork element (base plate), e.g. from a polystyrene foam, to form a floor slab of a building.
• the base plate 1 has both on its upper side 2 and on its underside 5 in each case a multiplicity of uniformly distributed, knob-shaped connecting elements 3.
• the knob-shaped connecting elements 3 have a substantially truncated pyramidal shape and are arranged such that each of four horrele- elements 3 a recess 4 is formed, in which a corresponding knob-shaped connecting element of an upper or lower side arranged further formwork element can intervene.

• the corner element 21 has dovetailed recesses 30 dovetail-shaped in a partial region of its first end face 28 of the vertical leg and strip-shaped projections corresponding to the second end face 31
• edge elements 21 to be connected can be quickly moved into a precisely defined vertical position in the relatively rough conditions of practice, there are at the ends of the groove-shaped recesses 30 stops 26, whose surfaces are slightly chamfered to prevent water can collect in these areas.
• corner elements 21 and the subsequent further edge elements 41 are formed such that the wall thickness of the respective edge element in the lower region 42 of the vertical leg 29 is greater on the outside than in the upper region 43.
• edge elements including the corner elements
• corner elements connected to each other laterally, so that a frame results, which is filled with loose side by side laid base plates 1 (in Figure 4, only one base plate 1 is shown for reasons of clarity).
• connection of the base plates 1 with the edge elements 21, 41 by 11 cover plates are placed on the prefabricated base trough so that they each cover a base plate 1 and the horizontal leg 27 of a peripheral element 21, 41 ( Figure 5).
• the formwork elements not only plate-shaped or L-shaped, but also have other shapes.
• the corner elements may also be inner corner elements (see FIG.
• knob-shaped connecting elements do not necessarily have to be designed in the shape of a truncated pyramid, even though this knobbed shape has proven particularly useful in practice.
• the base plates ie plates with top and bottom arranged knob-shaped connecting elements
• cover plates This is particularly useful when the wall thickness of the trough-shaped formwork is to be doubled on the bottom side.
