Abstract: The invention relates to a gutter system (1) comprising at least one frame unit (10), at least one cover unit (20) and at least one securing element (30), wherein the frame unit (10) comprises at least one receiving area (12) for arranging the cover unit (20), and wherein the securing element (30) is adapted to engage in the cover unit (20) and to releasably engage in the receiving area (12) so the cover unit (20) can interlock in the receiving area (12) of the frame unit (10). The invention also relates to a cover unit (20) and a securing element (30).

Abstract: The invention relates to a gutter system (1) with at least one frame unit (10), at least one cover unit (20) and at least one first damping element (14), wherein the frame unit (10) has at least one receiving area (12) for arranging the cover unit (20). The receiving area (12) of the frame unit (10) has at least three side walls (12.1; 12.2; 12.3; 12.4; 12.5), wherein the first damping element (14) is provided between the frame unit (10) and the cover unit (20) in such a way that the cover unit (20) is received in the frame unit (10) in a damping mariner in at least three spatial directions.

Abstract: A The manhole cover is described with a supporting structure device comprising force distribution ribs for supporting a top surface of the manhole cover which can be driven over, and a hollow force distribution cylinder arranged substantially centrally, in particular a circular force distribution cylinder, for supporting the force distribution ribs, characterised by a force distribution plate to relieve the load on the force distribution cylinder, wherein the force distribution plate at least substantially completely covers an underside of the force distribution cylinder in relation to the top surface, and wherein the force distribution ribs transform smoothly into the force distribution plate.

Abstract: A surface water drainage system according to the present invention includes a structure that can be installed in the ground, and a cover that can be laid onto an upper edge of the structure. Fixation devices that are attached to the cover include a locking system in a form of elastic hook elements fixed to edges of the cover that can be brought into snap-on engagement with other locking system on the structure in order to retain the cover on the structure.

Abstract: A one-piece drainage channel for surface drainage is disclosed that comprises a molded, elongate body, in particular made of concrete polymer, with an upper surface over which vehicles can travel and which comprises inlet openings that open into a channel compartment, with side walls and a floor and with end faces to which can be connected additional drainage channels, catch pits or similar drainage installations, wherein the channel compartment comprises adjoining boundary surfaces, in particular a ceiling boundary surface nearest to the upper surface, side boundary surfaces and a base boundary surface. In order to provide easier manufacture along with high stability, even in the case of large channel widths and lengths, it is proposed to construct at least one side boundary surface and the base boundary surface or the ceiling boundary surface so that the channel compartment tapers conically in the direction from one of the end faces to the other.

Abstract: The invention relates to a cover for a surface drainage device or similar hollow body that is to be embedded in the ground and to be opened. The cover comprises an upper surface over which pedestrian and/or vehicular traffic can pass, and at least one locking element that is attached to an underside of the cover such that the upper side is closed over the locking element. The locking element is disposed at a specified distance from the underside in such a way as to form an air gap for thermal insulation between the underside and the locking element.

Abstract: A surface water drainage system is provided that comprises a structure that can be installed in the ground, and a cover that can be laid onto an upper edge of said structure. Fixation devices are provided that are attached to the cover and comprise a locking means in the form of elastic hook elements fixed to edges of the cover that can be brought into snap-on engagement with other locking means on said structure in order to retain the cover on the structure.

Abstract: The invention relates to a drainage device for surface drainage, in particular to drainage channels with a channel body and a frame which fits on an upper edge of the channel body, comprising an outer arm and an inner arm between which the upper edge of the channel body sits, for housing a cover. According to the invention, simple economic production and assembly of the frame on the channel body may be guaranteed whereby the frame is embodied such as to be able to be cast within the body of the channel body on the casting thereof, or alternatively, may be fixed to the channel body by means of continuous jointing to a pre-fabricated channel body.
