Definitions

  • the invention relates to a fastening element for formwork and heat insulation components made of rigid foam, in particular for the shell-concrete construction.
  • the invention is therefore based on the object to provide a fastener for formwork and heat insulation components made of rigid foam, which is universally applicable, avoids fire and cold bridges and is cheap and easy to manufacture.
  • the formwork elements themselves should be improved and supplemented.
  • the invention is based on a fastening element of the type mentioned Type and is characterized by a plate which can be fixed to the component made of rigid foam and which is provided with further fastening means.
  • panels according to the invention enable a large-area connection to the surfaces of formwork and thermal insulation components made of rigid foam, with a large number of conventional and different fastening means then defining the panels and so that the rigid foam components can be easily carried out on other structures.
  • the plate on the one hand and the component made of rigid foam on the other hand can be provided with corresponding latching means, which are expediently formed, for example, by spaced-apart, continuous grooves in one part, for example the plate, and corresponding webs in the other part, for example in the component made of rigid foam .
  • the cross section of the grooves can be complementary to the cross section of the webs remaining between two adjacent grooves.
  • the grooves are expediently designed to be expanded at their base.
  • the continuous grooves and webs allow displacement and thus any placement of the panels with their fastening elements.
  • the cross-sectional shape of the grooves and webs should be dimensioned such that the frictional forces that occur prevent unintentional shifting even when shaken or when a concrete jet hits the concrete.
  • the plate can have any shape, but is advantageously designed in the form of a plate and has, on its rear side facing away from the component made of rigid foam, the respective fastening means which are arranged in, on or on a rear shaft of the plate are arranged. Concrete is used in particular as the production material for the plate and the shaft, so that the fastening element later forms a piece with the filled in-situ concrete of the formwork elements. A weakening of the concrete wall with regard to a fire breakdown is thus avoided.
  • one or more binding wires can be anchored in the shaft, which enable a tensile connection to neighboring components.
  • the fastening means can also be designed in the form of a straight or deformed rod anchored in the shaft.
  • the rod can be a round or flat rod.
  • a deformed rod can, for example, form a hook or an open or closed eyelet.
  • a threaded nut or a threaded rod can be fixed in the shaft. With the aid of screws or nuts, it can then be attached to or by means of any other parts, for example angles, perforated bands or the like, it also being possible to adjust the distance using the threads.
  • the shank is expediently provided with at least one and preferably two adjacent, circumferential grooves into which reinforcing bars can be inserted with precise fixation of their position and their distance from the outer surface of the concrete.
  • Two adjacent grooves allow the adjacent insertion of, for example, a horizontal and a vertical reinforcing bar.
  • two plates are combined into a pair via a deformable connecting piece.
  • Straight steel rods of different lengths enable the production of connecting pieces for the side walls of formwork elements with any internal width. Concrete walls of the desired thickness, even deviating from standard dimensions, can thus be easily realized will.
  • the connecting piece can also be shaped such that the plane of the two plates forms a desired angle to one another, for example an angle of 90 ° for the connection point between an outer wall and a vertically opening inner wall. Other angles allow the connection of ledges.
  • a ceiling finish can be achieved in a particularly expedient manner by embedding the rod in the concrete of the stone lying under the ceiling.
  • a large number of plates can also be combined with a common connecting element, for example when a special course, for example an arch in a wall, is to be realized.
  • a special embodiment of the invention provides a formwork element made of hard foam for the sheath-concrete construction with side walls which have grooves arranged at the same distance from one another, running from top to bottom and distributed over the entire inner surface of the side walls, with a plate made of hard foam arranged between the side walls the edges adjoining the side walls are provided with webs which correspond to the grooves.
  • the plate that forms the floor in the formwork element and determines the height of the girder or the lintel can be the cover of a roller shutter box, which is arranged under a keystone.
  • End walls arranged between the side walls of the formwork element and provided with webs and corresponding to the grooves in the side walls can accommodate roller shutter anchors for mounting a roller shutter, the anchors having anchoring parts that protrude through the end walls and are to be embedded in the concrete of the neighboring elements to be filled.
  • the fastening, formwork and thermal insulation elements according to the invention allow a very flexible use of the sheathed concrete construction, and even complicated shapes can be produced quickly and safely and in a reproducible manner.
  • the formwork elements are made with predetermined locking dimensions and the grooves and ridges within the formwork elements have a predetermined, smaller grid, it can be built without a grid, because both abutting walls and corners do not have to adhere to the grid, as will be explained below .
  • Free-standing surfaces of formwork elements made of hard foam can be secured with the aid of the fastening elements according to the invention so that no deformations occur when filling even high walls. Because of the height-adjustable fasteners and floor or ceiling panels made of hard foam between the side walls, any heights between the standard or grid dimensions of formwork elements can be achieved.
