Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • Devices for molding sewer shafts each having at least two connecting sleeves with an at least two preferably mutually rotatable molded jacket sections provided with sleeve inserts, such as socket mirrors, and at least one jacket segment having a jacket segment and a mold core arranged therein are e.g. the DE 25 41 612 C and DE 26 25 506 C. Sewage ducts of known standardization can be produced with these devices, the advantage being that the angular adjustability of the shaped jacket sections having the socket inserts means that sewer ducts with a different angular profile of the connecting sleeves can be produced with one and the same device.
  • shaped jacket sections having the socket inserts have bottom horizontal flanges on the bottom, which can be moved on stationary base rings.
  • the shaped jacket sections referred to as shaped jacket halves have, on the outside, toothed ring segments which cooperate with drive pinions in order to enable the adjustable jacket halves to be adjusted relative to one another.
  • a formwork for concreting sewer shafts with the features mentioned in the preamble of claim 1 is known from DD 245 113 A3.
  • the formwork has jacket segments which are fixed in position on the outside by clamping elements resting on the jacket segments.
  • the tensioning elements are inserted into the receptacles and can be removed from the formwork in the direction of the end faces.
  • the known device has the disadvantage that a simple detachment of the formwork from the cast sewer shaft is not possible.
  • the clamping rings resting on the molded casing can be connected to it by mortar residues and, on the other hand, the entire device, with the sewage shaft located therein, has to be lifted, e.g. to remove the bottom clamping ring from the molded jacket.
  • the object of the present invention is to develop a device of the type mentioned at the outset in such a way that sewer shafts with the desired course of the connecting sleeves can be produced using structurally simpler means, not only simple assembly of the device but also direct removal of the same from the cast sewer shaft is, so that an increased use of the device can be achieved.
  • Mechanical manufacture of sewage shafts should also be possible.
  • the elements are designed as circumferential closed clamping rings and are held at a distance from the molded jacket section and the shell segments projecting receptacles to the molded jacket and that the clamping rings have different diameters, with a clamping ring running in the bottom region of the device having a larger diameter than one has clamping ring running in the upper region of the device.
  • This clamping ring engages in receptacles, such as mounting brackets, which protrude from the outer sides of the shaped jacket sections or the jacket segment or segments so that the position is fixed to such an extent that the device can be filled with concrete or other desired materials without the risk there is that the elements slip against each other in an uncontrolled manner.
  • receptacles such as mounting brackets
  • At least one jacket segment extends from each side of the shaped jacket sections having the sleeve insert.
  • At least one jacket segment has a sleeve insert.
  • At least one free longitudinal edge of the shaped jacket section has a receptacle for a subsequent jacket segment.
  • the jacket segments experience an additional positional fixation, at least in the region of the molded jacket section, so that the overall stability of the device is increased.
  • the shaped jacket section having the sleeve insert has a U-shape in section, the side legs of which for releasably receiving subsequent ones Sheath segments are formed.
  • the receptacles are preferably longitudinal slots running in the area of the longitudinal edges.
  • the shaped jacket sections having the socket inserts are first positioned at the desired position of the clamping rings, and then in the Longitudinal slots of the molded jacket sections to introduce jacket segments of the desired arc lengths which overlap between the molded jacket sections.
  • the shaped jacket sections having the socket inserts are first positioned at the desired position of the clamping rings, and then in the Longitudinal slots of the molded jacket sections to introduce jacket segments of the desired arc lengths which overlap between the molded jacket sections.
  • protruding receptacles for the clamping rings ensure that the jacket segments cannot tip away when the device is filled.
  • the device in the interior of which a mold core is arranged coaxially and the socket inserts are connected to one another via shaped bodies or channel shaped parts, is filled with concrete or other suitable materials, the device can be removed immediately from the sewage duct to be produced if the material is to a certain extent is set or hardened that a change in shape is no longer possible. It is then only necessary to remove the clamping rings and the jacket segments or molded jacket sections from the sewage shaft, and in order to facilitate the removal of the empty molded jacket sections, these can be provided on the bottom with sliding elements such as rollers.
  • the elements can then be reassembled into a device in order to produce a further sewerage shaft.
  • the device according to the invention is also suitable for the mechanical production of sewage ducts.
  • the molded jacket on z. B. a plate can be fixed in position, which has an annular groove or circular recess corresponding to the shaped jacket periphery, in which the shaped jacket is positioned.
  • the clamping rings can be z.
  • hydraulic cylinders can be raised or lowered to open or close the shell.
  • the devices (12) and (14) each have a hollow cylindrical shaped jacket (16) in which a mold core (1) is arranged coaxially.
  • the shaped jacket (16) in the embodiment of FIG. 1 consists of side sleeves (10) having molded jacket sections or sleeve mirrors (2) and molded jacket segments (3) and (4) which are arranged to overlap to the extent that a molded jacket (16) results in a closed form.
  • clamping rings (8) and (9) are provided, which are formed by the shaped jacket sections (2) and the shaped jacket segments ( 3) and (4) protruding receptacle as slotted brackets (6) and (7) can be inserted.
  • FIGS. 2 and 4 The consoles (6) and (7) with the slots are in FIGS. 2 and 4 and the tensioning rings (7) and (8) introduced into them, which can also be replaced by other peripheral elements, are shown in FIGS. 1 and 3 clearly removable.
  • the mounting brackets (6) and (7) run on the one hand in the bottom area and on the other hand in the upper edge area of the shaped jacket (16), so as to ensure high stability for the entire device (12) and (14) to achieve.
  • the diameter of the lower clamping ring (8) is also larger than that of the upper clamping ring (9) so that the former can be inserted into the slots of the lower clamping ring brackets (6) via the protruding clamping ring brackets (7).
  • recess inserts (11) emanate from the socket inserts (10), which later establish a connection to the space left free by the casing core (1).
  • the angle of 180 ° shown between the opposite sleeve inserts (10) can be changed by rotating the shaped jacket sections (2), which are referred to as sleeve mirrors, against each other, the clamping rings (8) and (9) forming guides.
  • the shaped jacket segments (4) overlap more or less with the segment-shaped sections (18) and (20) starting from the socket mirrors (2) or with the shaped jacket segments (3) which can be referred to as angle shaped sheets .
  • Fig. 1 illustrates that the middle shell segments (4) with respect to the shell segment (2) starting segment segments (18) and (20) and the interchangeable metal sheets (3) run inside. Nevertheless, a lower or upper clamping ring bracket (6) and (7), which are generally provided with the reference numerals (22) and (24) in FIG. 1, is only required in the central region of the shaped jacket segments (4), without there is a risk that the segments (4) will tip away when filling the mold; because the segments (4) are supported on the outside by the segment sections (18) and (20) or by the shell segments (3).
  • the elements forming the mold jacket (16) are supported on a profile ring (5), within which the mold core (1) is arranged centered.
  • the profile core (1) has a flange ring (26) running around the bottom, the outer diameter of which is a step (18) of the profile ring (5). is adjusted.
  • the device (14) according to FIGS. 3 and 4 differs from that of FIGS. 1 and 2 essentially in that the shaped jacket sections (2), which are also referred to as socket mirrors and which have the socket inserts (10), have a U-shape having vertical longitudinal edges (30), (31), (32) and (33) of the side legs (34), (36), (42) and (44) receptacles (35,), (37), (39 ) and (41) for mold jacket segments (38) and (40) which can be introduced into them and which correspond to the segments (3).
  • These measures allow the elements to be used universally, since the distance between the U-shaped shaped casing sections (2) having the socket inserts (10) can be adjusted to an even greater extent.
  • the receptacles (35), (37), (38), (39) and (40), (41) have a U-shape on average, the inner spacing of the side legs depending on the material thickness of the shaped jacket segments (3) or (4) or (38) or (40) is adapted.
  • rollers (46) on the bottom side which then do not engage with the Floor surface shown, on which the device (14) is parked, can be supported when the shaped jacket sections (2) are tilted.
