Definitions
- the invention relates to a formwork element made of foamed hard plastic for the shell-concrete construction, consisting of two parallel plates with tongue and groove design on their edges and of webs connecting the plates together.
- the object of the invention is to improve a formwork element according to the type mentioned in the introduction in that with ensuring excellent thermal insulation on the room side a relatively quick vapor permeability, better use of the filled concrete as a heat accumulator and secure anchoring of fasteners is achieved.
- the solution to this problem is that the plate forming the outer jacket is thicker than the plate forming the inner jacket of the element and that the plate forming the outer jacket has a wider tongue and groove configuration than the thinner plate.
- the thinner, later on the room-side panel also improves the vapor permeability from the room side, so that moisture from the room can penetrate relatively quickly into the concrete core, which is located in the formwork elements that are assembled and filled with concrete , so that the moisture-related part of the indoor climate regulates itself quickly.
- the concrete core can also be used better as a heat store, since it is reached more quickly by the room heat and, conversely, can return relatively more stored heat into the room. Because of the relatively thin plate forming the inner jacket or the inside of the room, longer fastening means, in particular dowels, penetrate sufficiently deep into the concrete and thereby give more hold, so that even heavy objects can be fastened to such a wall.
- Such a formwork component has an increased breaking strength when using both stamped concrete and plastic concrete.
- no holes or voids are created during tamping directly below the downward horizontal surfaces of the connecting parts of the webs, since the ramming tool can easily reach these points or can safely bring concrete in the direction of these points.
- segregation can no longer take place, since coarser gravel parts of the concrete can reach these points.
- an increase in strength is also achieved by the fact that more concrete can be introduced into at least some of the spaces between the plate and the web, due to the recesses provided on the plate in question, so that a thicker concrete web is formed.
- the formwork element 1 used for the shell concrete construction in building construction consists of two mutually parallel plastic panels 2 and 3 made of foamed hard plastic, for. B. Styrofoam. At their edges or narrow sides, the plates are provided in the usual way with a training consisting of groove 4 and tongue 5.
- One of the panels is thicker than the other and is used to form a highly heat-insulating outer shell of the building's outer walls.
- the thicker plate 2 can be considerably thicker than thinner plate 3, e.g. B. three times as thick. In general, the thickness of the plate 2 will be on the order of 4 to 20 cm and preferably about 12 cm; the thickness of the thinner plate 3 will be of the order of 2 to 8 cm and preferably about 5 cm.
- the tongue and groove formation 4, 5 of the thicker plate 2 is also wider than that of the thinner plate 3. This stronger dimensioning of a tongue and groove design, with a correspondingly narrow fit, contributes to a firmer cohesion of the assembled formwork elements and is also less prone to breakage during transport and handling of the elements.
- the plates 2, 3 are preferably connected to one another by Z-shaped webs 6 and 7, as can be seen from FIG. 1.
- the middle part 6a, 7a of the webs extends on both ends up to the edges or narrow sides of the plates 2, 3 and can on be provided at one end with a pin 8 and at the other end with a corresponding recess 9.
- the regions 6b and 7b of the webs which are directly opposite the plates are advantageously rounded, polygonal or curved in another way (FIG. 2).
- the connection parts 6c and 7c of the webs 6 and 7 extend approximately over half the height of the plates 2, 3 and are flush at one end and flush with the plate edge and the end of the web center parts 6a, 7a.
- their inner horizontal region 6d or 7d is rounded in profile or curved in another way, as FIG. 3 clearly shows.
- At least the thicker plate 2 of the element 1 has cutouts 10, which lie opposite the area 6b or 7b of the webs 6 and 7 and enable thicker concrete connecting webs to be created later in the spaces between them.
- the webs 6, 7 can have provisions with the aid of which conventional reinforcing bars are fixed.
- profiles 11 can be integrated, which receive or fix reinforcing bars 12.
- the Z-shaped webs 6, 7 of the element 1 are arranged in a mirror-inverted manner relative to one another. This later results in a meandering course of the filled concrete, which means in particular an increase in the structural strength of the set concrete.
- the thicker plate 2 forming the outer jacket is preferably provided with vertical grooves 13. These grooves ensure improved adhesion of a plaster layer (not shown) on the outer surface of the plate 2.
- horizontal grooves 14 can also be provided. The grooves are about 2 to 3 mm wide and 2 mm deep.
- the formwork element described is advantageously made in length in pitch, z. B. in the masses 12.5, 25.50 and 100 cm.
- the height can e.g. B. 33.3 cm and the width z. B. 36 cm.
