Definitions

  • the invention relates to a method for producing a ceiling element.
  • the invention relates to a slab formwork for producing a ceiling element.
  • the object of the present invention is to alleviate or remedy at least individual disadvantages of the prior art.
  • the invention has the particular object of specifying a method and a slab formwork, with which or with which the use of lost ceiling panels is made simple and secure.
  • the casting of the ceiling element from the ground can be prepared.
  • the lost ceiling panel is disposed on the ceiling formwork frame, while the ceiling formwork frame is disposed in the intermediate position inclined from the first toward the second end portion toward the floor.
  • the slab formwork frame is easily accessible from the ground to attach the lost ceiling slab to the slab formwork frame.
  • the ceiling formwork frame is preferably arranged at an angle of at least 10 degrees, in particular of at least 20 degrees, preferably of at least 30 degrees, to a horizontal plane through the connection points of the first end region of the slab formwork frame with the floor supports.
  • the present method allows a safe and simple production of ceiling elements with at least one lost, ie remaining in the ceiling element, ceiling plate.
  • the ceiling element is made by supplying concrete to the lost ceiling slab.
  • the location and directional references such as “up,” “down,” “horizontal,” “vertical,” refer to a horizontal usage condition of the slab formwork frame for casting the slab member.
  • the slab formwork frame can also be arranged inclined to the horizontal in order to produce an oblique ceiling element.
  • the lost ceiling plate is preferably a ... plate used.
  • the lost ceiling panel is made of a material of the group consisting of gypsum, wood, wood composite, plastic, steel, aluminum and / or a combination thereof.
  • the lost ceiling panel may have reinforcements, e.g. Glass fibers, or have a reinforcement.
  • the lost ceiling slab has markings on the upper side (ie on the side facing away from the floor) which preferably illustrate a duct layout for the slab member to prevent the installation of ducts such as electrical wiring or piping on the lost prior to concreting Ceiling plate to facilitate.
  • the lost ceiling panel for connecting to the slab formwork frame in a holder of the Ceiling formwork frame inserted.
  • the lost ceiling panel can be connected without tools in the intermediate position with the holder of the slab formwork frame.
  • the holder preferably has a bearing surface for placing the lost ceiling plate.
  • the bearing surface preferably has one section each along two transverse and two longitudinal sides of a ceiling formwork frame which is rectangular in plan view. It is particularly preferred if the support surface extends continuously along the two transverse and the two longitudinal sides of the slab formwork frame. Accordingly, a peripheral support for the lost ceiling plate is preferably provided.
  • the lost ceiling slab does not protrude beyond the longitudinal and transverse sides of the slab formwork frame. Due to the lack of overhangs, the safety when installing and removing and the quality of the cast ceiling element is increased.
  • the holder preferably has a holding web which projects upwards from the supporting surface.

  • At least two slab formwork frames each with a lost ceiling slab in the raised position next to each other are arranged in a preferred embodiment, before the ceiling element is poured together with the lost ceiling panels on the slab formwork frame.
  • two adjacent longitudinal or transverse sides of two slab formwork frames can be supported on two common slab props.
  • a gap between facing side surfaces of the lost ceiling panels is filled after casting the ceiling element with a filling compound.
  • the gap is formed in particular as a negative mold adjacent holding webs of the ceiling formwork frame.
  • a sealing tape is disposed along adjacent edge portions on the tops of the lost ceiling panels.
  • the sealing tape makes it possible to cover the gaps between the lost ceiling panels due to tolerances and to prevent soiling of the lower ceiling surface.
  • a gap between the lost ceiling slab and the slab formwork frame can also be closed. Furthermore, the pivoting of the frame can be facilitated.
  • the slab formwork frame has an overhang along its longitudinal and / or transverse sides, i. a curvature upwards, up.
  • the elevation may be, for example, several millimeters to centimeters.
  • the lost ceiling panel in the use position in an upwardly arched state wherein the plate is preferably arranged on bearing surfaces in the slab formwork frame for the lost ceiling plate, are present.
  • This elevation allows a significant weight reduction in the dimensioning of the slab formwork frame with respect to the flatness of the finished ceiling element.
  • the floor props or the at least one additional floor prop can be removed or transferred to an inclined rest position. Thereafter, the slab formwork frame can be arranged in the intermediate position. Subsequently, the slab formwork frame can be detached and removed from the remaining in the support position ceiling supports.
  • Fig. 1 shows a slab formwork 1 for concreting a ceiling element 2 (see Fig. 12 . 14 ).
  • the slab formwork 1 has two ceiling supports 3 for supporting a first (longitudinal) end region 4 of a slab formwork frame 5 and two further floor supports 6 for supporting a second end region 7 of the slab formwork frame 5.

  • the other slab formwork frame together with further lost ceiling panels 10 are supported on additional ceiling supports 11.
  • the other slab formwork frame 9 are formed according to the slab formwork frame 5 and the other lost ceiling slabs 10 corresponding to the lost ceiling slab 8.
  • the ceiling supports 3, other ceiling supports 6 and additional ceiling supports 11 may also be identical.
  • the structure of the slab formwork 1 goes out of the Fig. 2 to 5 out.
  • each ceiling support 3 has an upper ceiling support part 13 and a lower ceiling support part 14, which are adjustable in the vertical direction to adjust the height (ie the vertical extent) of the ceiling support 3 depending on the application.
  • the ceiling support 3 has a locking device 15 for locking the upper ceiling support part 13 in different height positions relative to the lower ceiling support part 14.
  • the locking device 15 may have a bracket 16, which can be inserted through corresponding, spaced apart in the vertical direction holding openings 17 of the upper ceiling support member 13.
  • a head portion 18 is further provided, which is adapted for a detachable connection with the first end portion 4 of the ceiling formwork frame 5.
