A double clutch transmission with two clutches connected to a drive shaft and to one of two transmission input shafts. Fixed gears are coupled to the input shafts and engage idler gears. Several coupling devices connect the idler gears to a respective countershaft which have an output gear that couple gears of an output shaft such that forward and reverse gears can be shifted. Three dual gear planes each comprise two idler gears, each supported by a respective countershaft, and one fixed gear. In each dual gear plane, at least one idler gear wheel can be used for implementing at least two gears so that at least one winding-path gear can be shifted via a shifting device.

The clamping element is supported in a positive fit on the base plate in the direction of traction of the traction element in the anchoring for pre-stressed strip-shaped traction elements on supporting structures. The traction element is received between a base plate which is fixed to the supporting structure and a clamping plate which can be clamped against the base plate and is fixed by adhesion and clamping. The clamping plate can include, on each side of the traction element, a retaining cam plate which projects in a downward manner and which engages in a retaining recess of the base plate, or can include a retaining projection which supports a stop which is connected to the base plate. The stops on the upper side of the base plate are welded push blocks which are arranged on both sides and/or in the region of the front side of the clamping plate. The clamping plate can be secured in the position thereof such that it supports the base plate in a positive fit by a positioning device which is mounted in a detachable manner in the direction of traction of the traction element. The positioning device is a threaded rod operating between the clamping element and a bridge connected to the base plate.

The invention relates to a mixture composition having dispersing properties, containing copolymers based on unsaturated mono or dicarboxylic acid derivatives and oxyalkylene ethers as component I and water-soluble copolymers and terpolymers containing sulfo groups having an average molecular weight of 50 000-20 000 000 g/mol as component II. By combining both components, which can be respectively characterized by four different structural units, it is possible to obtain mixture compositions which can, more particularly, be used as dispersing agents for organic and/or inorganic pigments and fillers, in addition to known applications in the field of structural chemistry. In the field of structural chemistry, the mixture compositions are suitable for use on account of the dispersing properties thereof, particularly in ceramic systems and in water-based painting and coating systems. Independently of the dispersing effect thereof, the described mixture compositions are also excellent solvents, wherein they can be used more particularly as casein substitutes, even in self-levelling gap-filling materials and trowelling compounds by virtue of the stabilizing effect thereof. The inventive mixture composition combines known positive properties of components I and II and can be used in new fields of application, even in the non-structural chemistry field.
摘要:
Pre-stressed, strip-type tension members are applied to supporting structures, especially concrete supporting structures. To this end, a clamping device is used to pre-stress the tension member at least at one end, at a distance from the surface of the supporting structure, by a temporary clamping element which is fixed to the tension member, and the tension member is then pressed onto the surface by at least one permanent brace. The two temporary clamping elements are removed from the surface once the tension member has been pressed onto the surface.
摘要:
A tensioning device for strip-shaped tension members on supporting structures, especially concrete supporting structures, exhibits a tensioning traverse, which is detachably fastened to a base plate that is permanently fastened to the supporting structure. A prestressing ancho), which is connected to the strip-shaped tension member by means of clamping, may be displaced by means of pressing elements for the purpose of applying tension to tension member and supported against the tensioning traverse or the base plate. A guide body, which supports the tension member so that it may glide, at least upward, is arranged between the tensioning traverse and the prestressing anchor so as to be stationary. The guide body exhibits a guide slit that accommodates the tension member so that it can glide, and it is mounted on a guide support that is connected to the tensioning traverse so as to be deflection resistant.
摘要:
A reinforced or prestressed concrete structure is strengthened and/or restored by attaching a strip-shaped tensional member thereto. Prior to attaching the tensional member, a central portion thereof is prestressed. Then, the tensioned central portion is bonded to a concrete surface of the concrete structure by a first adhesive having a high deformation modulus. Thereafter, the non-prestressed end portions of the tensional member are bonded to the concrete surface by a second adhesive having a low deformation modulus, whereby the second adhesive is substantially less deformable than the first adhesive.
