Further advantages of the invention are the difference in height between the Rip-45s, which run perpendicular to one another pen depending on the steel diameter and in

The invention relates to a permanent dependence on the concrete cover. In particular formwork panels, of which a plurality of those next to one another with more elaborate reinforcements do not need to be laid, supported by removable supports and panels made especially for these reinforcements with a preferably rectangular base are used; Only one reinforced concrete ceiling or wall is formed and 50 normal standard panels are used, on which the reinforcement, made of concrete, is put together on the room side,

A reinforced concrete ceiling plate is known which takes into account the required in-situ concrete individual ceiling panels are formed, the already 55 cover for the reinforcing steel provides the permanent the reinforcement panel required to stiffen the ceiling has a flat surface on the outside tion included. For this reason, the top layer, which replaces plastering, is available. The joint Reinforcing bars out of the ceiling panels and between the formwork panels can only be reached in spach work in the area of mutual approach if closed surfaces are desired, two plates alternately one inside the other. Will then- 60 According to an advantageous embodiment of the invention the in-situ concrete on this prepared ceiling is the mutual spacing of the longitudinal ribs pours, then the reinforced concrete slab ceiling forms a length that remains about 5 cm or a multiple of this dimension Formwork, and in the area of the protruding- agrees on the same spacing of the bars from The iron connects the plates with each other, so reinforcement meshes.

that in the end a closed ceiling is created. 65 On the one hand, through the ribs, the intimate Ver-Um the intimate connection between the cover plates connection of the formwork panel with the in-situ concrete and the cast-in-place concrete, the ceiling tiles are improved; on the other hand, this results in a verten on the side facing the in-situ concrete, even greater load-bearing capacity for the panel itself.

Claims (2)

1 2 provided with elevations in the form of ribs Patent claims: (German Patent 943 905). The main disadvantage of this known ceiling 1. Permanent formwork panel, one of which is a construction that the individual part-majority placed next to each other by removable 5 pieces must be mutually tension anchored and Bare supports are supported and preferably that the in-situ concrete is no longer reinforced with reinforcement rectangular base the formwork is reinforced. Should such a reinforcement pre-reinforced concrete ceiling or form a wall and those, which are excluded, then concrete must be produced in the conventional way, and additional spacers must be worked flat on the room side, and on the side of the in-situ concrete of the ceiling or io because the ribs do not readily match those of the required wall is provided with ribs, thereby lending concrete cover corresponding to the reinforcement characterized in that the ribs have a grid-like height. perpendicular to each other and with a rectangular base. It is the object of the invention when using surface of the formwork panel parallel to its side - a permanent formwork the use of a conventional edge ve-run that the in the direction of support of the 15 reinforcement in in-situ concrete.
Panel running longitudinal ribs (3) are higher ribs than the perpendicular to them running transverse shuttering panel of the type mentioned (4) and that the difference in height between that, according to the invention, the ribs grating the longitudinal ribs (3) and the transverse ribs (4) approximately perpendicular to each other and at rectangular shirt is equal to the diameter of the in Tragrich ao base area of the formwork panel running parallel to its direction, the furthest outer side edges that are in the direction of the reinforcing steel (S), while the height of the ribs panel is higher than those above the on-site concrete side The surface of the table is equal to the transverse ribs running perpendicular to them and that the required concrete cover of the concrete is the difference in height between the longitudinal ribs and the steel with in-situ concrete. 95 the transverse ribs approximately equal to the diameter 2.
