Definitions

  • the invention relates to a hollow floor for covering a supporting floor, which has a cover layer, a support surface, supports and at least one interior extending between the supports and is at least partially formed from individual formwork elements, the edges of which overlap and have a seal running parallel to them.
  • Such a hollow floor consists of a supporting floor, formwork elements and a top layer, which is applied as an upper floor to the bearing surface of the formwork elements in the form of liquid screed.
  • the formwork element has downwardly projecting supports with the undersides of which the formwork element rests on the sub-floor.
  • the edges of the formwork elements are designed as uniformly profiled strips which lie at the level of the raised surface areas of the formwork element and overlap when stringing formwork elements together. Between the outer side of supports facing the respective edge and the outermost boundary of the edge, the edges have a groove-like bulge, so that the bulge of two adjacent formwork elements can be placed one inside the other.
  • the formwork elements of such a hollow floor which consist of flexible material, have a seal in the form of a bead in the most unstable area of the contact surface of the formwork element.
  • this requires such a viscosity of the screed that a time-consuming and therefore expensive mechanical smoothing of the screed surface must take place.
  • Flowing screed material to be applied generally has a weight of 75 to 80 kg / sqm. This relatively high weight alone causes the sealing surfaces to gap apart in the unstable edge areas, as a result of which screed material passes between the formwork. In the case of low-viscosity screed, this document therefore proposes to glue or weld the edges together. However, this is very time-consuming.
  • the hollow flooring known from US-A-3352079 consists of formwork elements which are placed on a supporting floor with their supports and on the bearing surface of which a cover layer in the form of a poured cement material is applied.
  • the cavity created between the supports can serve as an air duct for heating purposes, for example.
  • the edges of these formwork elements have semicircular beads outside the column area. Adjacent formwork elements are arranged so that the beads of adjacent edges overlap and interlock.
  • the beads In order to prevent warping of the edges or unintentional decoupling or misalignment of the formwork elements when entering, the beads have openings which are brought to cover during assembly, so that a correspondingly shaped end of a support column can be inserted and bent through the opening, while the other end of the support column is supported on the supporting floor.
  • the seal is designed as a labyrinth seal, which as a system of beads runs through the formwork element in the area of its support surface and has crossing points in the area of the supports.
  • a hollow floor essentially consists of formwork elements (1), supports (2) integrated into the formwork elements (1), one of the formwork elements (1) in the area of their vertical support surface (3) covering cover layer (4) and one between the Supports (2) extending interior (5), which is delimited in the vertical direction upwards by the support surface (3) and in the vertical direction below by a supporting floor (6) carrying the formwork elements (1).
  • the formwork element (1) has side edges (7, 8, 9, 10) in the region of its lateral boundaries. In each case two of the side edges (7,8,9,10) meet in the area of corners (11,12,13,14) essentially at right angles. Seals (15, 16) are arranged in the area of the side edges (7, 8, 9, 10). The seals (15, 16) are designed as labyrinth seals (17). The seals (15) arranged in the region of the side edges (8, 9) are each formed from three beads (18) which extend essentially parallel to one another. Seals (16) arranged in the area of the side edges (7, 10) are essentially designed as a bead (19) extending parallel to the side edge (7, 10) assigned to them.
  • the beads (18, 19, 20, 21) are essentially trapezoidal and have their largest extension in the horizontal direction in the area of the support surface (3).
  • the bead (19) extending between the beads (18, 20) has a greater extent in the vertical direction than the beads (18, 20).
  • the beads (21) are in the area of their outer boundary the course of the inner boundaries Beads (20) adjusted.
  • the beads (20) can thereby accommodate beads (21) that reach into them when formwork elements (1) are joined together.
  • the bead (19) extends in the area of its lower limit (22) in the vertical direction essentially arcuate. As a result of this arcuate course, the bead (19) has a greater extent in the vertical direction in the area of its boundaries facing the supports (2) than in an area between these boundaries.
  • the beads (18, 20, 21) run essentially tangentially to support openings (23), which are spanned by support casings (24) in the area of the support surface (3).
  • the column envelopes (24) span cuboids with their essentially perpendicular center lines.
  • the support openings (23) are each connected by beads (18, 19, 20) crossing them in the area of these support openings (23).
  • the crosswise arrangement of the beads (18, 19, 20) stiffens the formwork elements (1).
  • the beads (18, 19) run essentially tangentially to the support openings (23), the beads (19) run with their center lines through the center line of the support envelopes (24).
  • an edge (25, 26) is provided between the side edges (8, 9) and the support openings (23) arranged facing them.
  • the side edges (7, 10) run essentially at a distance from the beads (21) which corresponds to the distance of the beads (19) from the beads (20). This arrangement of the side edges (7, 10) in the area of these side edges (7, 10) of the column coverings (24) only results in partial areas resulting from a vertical cut.
  • the pillar coverings (24) extend in conical union and have their largest diameter in the horizontal direction in the area of the pillar openings (23). In the area of their lower boundaries in the vertical direction, the support envelopes (24) are delimited by support bottoms (27).
  • An inspection opening (28), which is closed by an inspection cover (29), is arranged in the area of the cover layer (4).
  • the inspection opening (28) is delimited in the horizontal direction by a frame (30) which essentially consists of a base leg (31) which faces the bearing surface (3), a vertical web (32) which extends essentially in the vertical direction, and an in turn horizontal leg (33) is formed.
  • the inspection cover (29) rests on the base leg (31) and essentially closes in the vertical direction at the top with the viewing leg (33).
  • the frame (30) has adjustment webs (35), in the area of which a height adjustment (36) is arranged.
  • the height adjustment (36) is essentially designed as a threaded bolt (37) which engages with an external thread (38) in an internal thread (39) arranged in the region of the adjustment web (35).
  • the adjustment web (35) has reinforcement webs (40) in the area of its boundaries facing the threaded bolt (37). With its lower end in the vertical direction, the threaded bolt (37) rests on the support base (27).
  • edges (25, 26) can lie in one plane with the rest of the contact surface (3). However, it is also possible to arrange the edges (25, 26) offset vertically downward relative to the rest of the bearing surface (3) and thereby also provide a substantially flat formwork element (1) resting on one another in the area of the seals (15, 16) To ensure contact surface (3) and supports (2) extending in the area of the entire extension of the formwork elements (1) to the supporting floor (6).
  • the formwork element (1) has a corner configuration which allows more than two formwork elements (1) to rest on one another avoids.
  • the formwork element (1) has bevels (41) in the area of the corners (12, 14) and a square recess (42) in the area of the corner (13).
  • the bevels (41) are provided at two opposite corners (12, 14). They each have a base (50) which encloses an angle of 135 degrees with two adjacent side edges (7, 10; 8, 9).
  • This base (50) runs on a support opening (51, 52) located in the area of the corner (12, 14), which is halved by the base (50).
  • This diameter line spans a vertical plane, which the supports (2) arranged in the corners (12, 14) cut in half and in this way form half supports (53, 54).
  • These half supports (53, 54) form a complete support (2) with corresponding half supports (55, 56) of an adjacent formwork element (57).
