Patent number: 9222358Abstract: A sealing arrangement for shaft and tunnel constructions. The sealing of gaps between components of shaft and tunnel constructions is improved, in particular if the components are misaligned. For this purpose a) the sealing arrangement (1) comprises at least two components (2), which lie against each other at butt sides (3) so as to form a gap (4), b) the components (2) have an elastic sealing profile (5) on each butt side (3), and c) the sealing profiles (5) of the butt sides (3) that lie against each other lie against each other on a contact plane (6) and bridge the gap (4) in a sealing manner. The sealing profiles (5) have areas (7, 8) of different hardness arranged in alternation in the transverse direction (9) perpendicular to the respective profile longitudinal plane (10), the sealing profiles (5) of butt sides (3) that lie against each other differing from each other in the arrangement of the areas (7, 8) of different hardness in the transverse direction (9).Type: GrantFiled: November 29, 2010Date of Patent: December 29, 2015Assignee: Daetwyler Sealing Technologies Deutschland GmbHInventors: Heiko Hoeft, Holger Gutschmidt, Andreas Diener, Andreas Artus, Marc Fischer, Matthias Klug

Publication number: 20090148658Abstract: The invention relates to a sealing arrangement composed of at least: two adjoining structural parts (2) made of concrete, steel, reinforced concrete, cast iron or other materials, and a sealing profile (8) which is made of polymer material and sealingly bridges the gap (4) between the two structural parts (2). The sealing arrangement according to the invention is characterized in that: the sealing profile (8) is composed of two or more co-extruded sealing parts (A1, B1) that form an adhesive join, the sealing parts being produced using at least two different types of polymer materials that are distinguished by having common elastic properties but having different mechanical and/or chemical and/or biological properties. Advantageous co-extruded sealing part constructions and material combinations are proposed.Type: ApplicationFiled: August 18, 2005Publication date: June 11, 2009Applicant: PHOENIX DICHTUNGSTECHNIK GMBHInventors: Holger Gutschmidt, Heiko Hoft, Andreas Diener

Patent number: 6592296Abstract: A sealing assembly comprising two abutting components and a sealing profile produced from an elastomeric material, which bridges the gap between the two components to form a seal. The components are configured in particular as sections which are assembled into a tubular tunnel thus forming transverse and longitudinal joints. There is also a sealing profile being located in turn in each recess, thus forming a cornered sealing framework. There is also a lubricant for the contact surfaces between each component and the sealing profile, in particular for the contact surfaces between two sealing profiles. The sealing assembly has at least one sealing profile that has at least two protrusions in the vicinity of the contact surfaces. The protrusions form a sealed chamber, in which the lubricant is contained.Type: GrantFiled: November 28, 2001Date of Patent: July 15, 2003Assignee: PhoenixInventors: Holger Gutschmidt, Heiko Höft, Dieter Kassel

Patent number: 6575664Abstract: A sealing arrangement which comprises at least two abutting components that form a gap therebetween and a seal that sealingly bridges the gap. The inventive sealing arrangement is characterized in that the seal entirely consists of a matrix or is provided with a matrix representing a composite system. The matrix is combined with a base body and is a pasty mixture comprising a water-soluble material. A lubricant and a swelling agent which can be activated by means of water as well as optionally additional additives are mixed into the material. In an advantageous embodiment, the matrix is introduced into the chamber. The wall of the chamber is configured in the form of a web that can be torn out. The web is removed before assembly. The base body consisting of an elastomeric material is provided with channels and grooves which extend in an extruded-like manner.Type: GrantFiled: May 14, 2001Date of Patent: June 10, 2003Assignee: Phoenix AGInventors: Dieter Kassel, Werner Degel, Holger Gutschmidt

Patent number: 6434904Abstract: The invention relates to a sealing device consisting of two contiguous building elements made of concrete, steel, reinforced concrete, cast iron or other materials, and a shaped sealing element made of an elastomer material which is inserted into a recess and bridges the gap between the building elements in a sealing manner. The building elements are in particular segments which are assembled into a tube-like tunnel such that transverse and longitudinal joints are formed. Each segment has a recess which runs around all bearing surfaces and has two outer side faces and a base side. A rod-shaped sealing element is positioned in the recess. According to the invention the recess within the central area of its base side has a support for the shaped sealing element such that two parallel recesses are formed. Each recess has an outer side face, an inner side face and a base side and a shaped body is housed in each recess.Type: GrantFiled: December 1, 2000Date of Patent: August 20, 2002Assignee: Phoenix AktiengesellschaftInventors: Holger Gutschmidt, Dieter Kassel
