Definitions

  • the invention relates to a cavity floor formwork according to the preamble of claim 1.
  • a cavity floor formwork which consists of foil plates with molded foot shells and surrounded by deformation areas.
  • the foot covers are arranged at such mutual distances that they adapt to an uneven contour of the subfloor when the screed is applied.
  • Such cavity floor formwork is simple and inexpensive to manufacture, but has the disadvantage of low strength. With a film thickness of 0.6 to 1.5 millimeters and a foot spacing of more than 11 centimeters, the film formwork is too weak to be able to bear the weight of a person.
  • the formwork must be accessible, for example when laying the hoses with which screed is pumped onto the surface, or if unforeseen events, such as leaks, occur when pouring the liquid screed.
  • DE-OS 21 64 897 describes a channel-like formwork for a beam frame, on which raised floor panels are laid after pouring with screed.
  • the formwork channels have holes under which foot covers are placed, which bump into the sub-floor.
  • These foot covers are designed in the manner of elastic balloons, which adapt to any unevenness in the sub-floor when filled with the screed. The foot covers are thus elastically stretchable.
  • Such foot covers with balloon-like wall parts are difficult to manufacture.
  • the foot covers must be attached individually to the formwork channels. It is not an area-covering cavity floor formwork.
  • DE-OS 31 13 633 describes a cavity floor formwork according to the preamble of claim 1. With this formwork, each foot cover must also be individually fastened to the rigid formwork panel and the entire formwork must be level-supported before the screed is brought in.
  • the invention has for its object to provide a cavity floor formwork, in which the foot covers automatically adapt to unevenness in the sub-floor and which has such a high load-bearing capacity that it is easy to walk on and easy to manufacture.
  • the cavity floor formwork consists of two panels, namely the relatively rigid formwork panels, which are provided with holes, and the foil panels arranged underneath, on which the foot covers are formed.
  • the formwork panels distribute the load on the foil panels so that the foil panels do not buckle when they are walked on.
  • the foot covers of the film plate can be moved downwards due to their movable arrangement under the weight of the screed mass that is in and on them. In a flat area of the sub-floor, all foot covers rest evenly on the sub-floor, so that individual foot covers do not stretch. However, if an insulated foot cover stands over a valley of the sub-floor while the neighboring foot covers stand on the sub-floor, then this one foot cover lowers into the valley until it has gained firm hold.
  • the formwork does not adapt overall to the contour of the subfloor, but such an adjustment is only carried out in isolation on individual foot covers, while the formwork panels remain at a uniform level.
  • the film panels and the formwork panels can generally be stacked independently of one another, the film panels forming a separate stack and the formwork panels forming another stack. Both types of panels can also be laid individually and independently of one another. Before laying, however, the film panels are preferably each individually assigned to a formwork panel and fastened under this formwork panel, for example by gluing or tacking. The resulting composite panels can then be placed as a unit on the sub-floor.
  • the film plates each have a substantially horizontal deformation area around a foot cover and a support area around this.
  • the support area lies essentially over the entire surface of the formwork panel, regardless of the size of the load on the foot cover. Neither the foot cover itself nor the support area are deformed by the action of a load. The only thing that is deformed is the annular deformation area, which determines the height of the relevant foot cover.
  • relatively rigid formwork panels 10 are provided, which are flat and e.g. are made of plasterboard. These formwork panels have holes 11 arranged in the manner of a grid.
  • a film plate 12 is arranged, which consists of a thermoformed plastic film, which is a film thickness in the original state from about 0.6 to 1.5 millimeters.
  • Foot covers 13 are formed in the film, which in the present exemplary embodiment have a circular cross section and taper conically towards the bottom.
  • the foot covers 13 are closed at their lower ends 14 and they transition at their upper ends into a horizontal deformation region 15 which surrounds the upper end of the foot cover in a ring.
  • the horizontal deformation area 15 forms a step, from which the film plate rises into a likewise horizontal support area 16. While the foot cover 13 has a circular cross section, the circumference of the deformation region 15 is square, with rounded corners and arcuate edges.
  • the support area forms a grid-like pattern between continuous and interconnected streets between the foot covers, as shown in FIG. 2.
  • Adhesive strips 17 are fastened on the film plate 12 in the support area 16. These adhesive strips 17 can be covered with removable protective strips. With them, the film plate 12 is attached to the underside of the formwork plate 10.
  • the foot covers 13 have e.g. a height of 6 centimeters.
  • the height difference between the deformation area 15 and the support area 16 is approximately 10 to 15 millimeters.
  • the support area 16 has a width of approximately 4 to 8 centimeters.
  • the film panels 12 are at the edges 18 with their support areas 16 slightly above the formwork panels 10, so that the edge 18 of a film panel between the edge 18 of the adjacent film panel and the adjacent formwork panel 10 are inserted can and both edges 18 overlap each other under the butt joint 19 of the formwork panel 10. In this way, the butt joint 19 is sealed by the film plates 12.
  • pourable screed is poured over the formwork. This screed penetrates through the holes 11 into the film plate and fills the foot covers 13. If a foot cover does not stand on the under floor as a result of an unevenness in the sub-floor, the deformation region 15 deforms under the weight of the screed mass so that this foot cover is lowered, as shown in Fig. 1 by dashed lines 20.
  • the deformation regions 15 also allow one of the foot covers 13 to be pushed up, as is indicated in FIG. 1 by the dashed lines 21. As a result, the foot cover deflects when individual elevations occur in the sub-floor, so that damage due to overload does not occur.
  • the deformation area 15 is arranged at the same height as the support area 16 in the relieved state of the formwork panel.
  • the deformation area 15 is formed here like a bellows with concertina-like ring folds so that its length can increase when the foot cover 13 is lowered.
  • the state when the foot cover 13 is lowered is indicated by dashed lines in FIG. 3.
  • the holes 11 of the formwork panel 10 are only arranged over the foot shells 13, but they do not extend into the area 15 covering the deformation area Area inside.
  • the filling takes place at the lower end of the foot covers and continues upwards until the entire space between the film plate 12 and the formwork plate 10 is filled to form a support foot. Thereafter, the flowable screed rises above the formwork panel 10 and forms a later accessible screed layer there.
  • the mutual distance between the foot covers is about 20 to 25 centimeters.
  • the thickness of the formwork panel 10 is 8 to 20 millimeters.
  • the screed is filled, for example, at a height of 3 to 4 centimeters above the formwork panel.
