Definitions

  • the invention relates to a formwork system for forming a transition of a reinforcement of a concrete component to a neighboring in a connecting direction, further concrete component, or the front end of a concrete formwork, comprising two formwork elements and a central element, preferably wherein the formwork elements parallel, planar, vertically aligned Schalphaseute , wherein the middle element is arranged between the shell elements in the region of one end of the shell elements, and wherein in each case elastic sealing lips are arranged between the shell elements and the middle element.
  • a generic formwork system is from the DE 198 00 569 C2 known.
  • Formwork systems are used to make concrete components on site.
  • the formwork system limits to the four sides (and down) a space in which uncured, liquid concrete is poured. After hardening of the concrete, the formwork is removed, and a solid concrete component is released.
  • Reinforcements are steel structures, in particular reinforcing mesh or parallel oriented round steel, which are poured into the concrete.
  • a typical wall of a building contains one or two levels of reinforcement aligned parallel to the wall surface.
  • the reinforcements In order to obtain an improvement in the strength of the concrete component also and just at the interfaces of adjacent sections, the reinforcements must be conducted across the interfaces. This means, the reinforcement must protrude from the formwork during filling of the concrete and during hardening.
  • a formwork system is proposed, with which two levels of reinforcement can be carried over the front end of a concrete wall section.
  • the formwork system on two vertically oriented system elements, which can be attached to the front side, for example, two parallel, opposing, spaced apart, flat and vertically oriented formwork elements.
  • the system elements are connected to a central part by means of tongues, plates and wedges, wherein in each case a gap remains between the system elements and the middle part.
  • the reinforcements are guided through the gap.
  • the gap is covered by elastic sealing lips, which fit tightly against the reinforcements and cause a substantial sealing of the gap for the uncured concrete.
  • a disadvantage of this known formwork system is fixed rigidly with this formwork system thickness of the concrete wall can be created. To change the thickness of the concrete wall, at least the middle part must be replaced.
  • Another disadvantage is the rigidly fixed with this formwork system depth of the concrete cover of the concrete wall can be created.
  • the depth of a concrete cover is the distance between the surface and the underlying reinforcement inside a concrete component.
  • the depth of the concrete cover is defined in the known formwork system with the associated system element. For a change in the depth of the concrete cover must be replaced in any case, the associated system element.

  • US-A-3,731,902 discloses a formwork system having the features of the preamble of claim 1.
  • the formwork system limits a space for filling with liquid concrete by the two formwork elements (to which further formwork elements and / or already hardened sections of a concrete component and / or other concrete components can connect), the middle part, the side surfaces of spacer profile elements and at least two elastic sealing lips. Due to the area of the sealing lips, which each span a gap between the uppermost spacer profile elements of two opposite mounting positions, the reinforcements can protrude.

  • an elastic sealing lip is arranged on the respectively uppermost spacer profile element of each mounting position.
  • the sealing lip is typically made of rubber, such as a hollow rubber profile.
  • the sealing lips of those uppermost spacer profile elements which are mounted on mutually facing mounting positions are pressed against each other.
