- the fittings 9a and 9b can be screwed through the bottom 4 therethrough.
- FIG. 3 which shows the mold bottom 3 without mold jacket 2, it is intended to produce a channel with a radially continuous section and two sections which open at an acute angle. For this purpose, in turn, only straight fittings 14 are required, which must be cut to length and trimmed accordingly. As can be seen in FIG. 3, it is by no means necessary to specify uniform cross-sectional dimensions for the slug parts.

- This bottom mold 1 in turn has one of a mold shell 2 enclosed Mold bottom 3, which is pot-shaped and carries on its bottom 22 a replaceable bottom 4, which has a continuous, adapted to the inclination of the Gerinnege materialss inclination. Since thus the channel slope is already taken into account by the inclination of the bottom 4, the fittings 9 need not be circumcised to form the Gerineverile with respect to their height. Accordingly, shaped pieces can be prefabricated with a profile cross-section which corresponds exactly to the channel cross-section, the shaped pieces 9 only having to be cut to length accordingly.
- the shaft bottom can also be produced separately from the pot-shaped shaft with a flat bottom and subsequently be inserted into the pot-like shaft.
- a bottom mold is required, which has a corresponding bottom 4 within a mold shell 23.

- a seal 24 in the recess body 11 is formed in two parts, for example composed of two pipe sections 11 'and 11 ".
- a cutting device here in the Formkö ⁇ er 8 already provided before its attachment in the bottom mold 1 heating wires 29 are used, which are connected to a power source when stripping and then a simple cutting out of a wedge-shaped part allow (see Fig. 18 and 19) - by moving out in each different directions 29 'and 29 ".
- a strip 30 is provided as a separating aid, for example a tear-resistant adhesive tape which surrounds the shaped body 8 or the shaped piece 9 at least at one point of its longitudinal extent. This band 30 then allows easy gripping and pulling out of the shaped body 8 or shaped piece 9 from the channel.
- the band 30 is expediently used in a provided from the outset on Formgro ⁇ er 8 and extending around the circumference of Formgro ⁇ ers 8 depression, the depth of this recess is dimensioned such that when applied tape 30 a completely smooth surface 31 of the molded body is given.
- the invention is of course not limited to the illustrated embodiments, which merely serve to illustrate the concept of the invention, which consists in the provision of prefabricated fittings 9 with adapted to the respective channel cross-section profile cross-section of various channels courses by a suitable assembly of the separated pieces 9 of the pieces to be able to realize without having to do without a mechanical production.
- a matte foam in particular the well-known under the brand "Styrofoam” rigid foam plastic, has proven to be in a simple manner in molds to the Fittings 9 can be foamed, after foaming has a sufficiently high compressive strength and dimensional stability, can be easily cut by suitable cutting tools, such as hot wire, saws, knives, and ultimately represents a very cheap product.
- fittings made of polystyrene Styrofoam 8 can be made in a concrete plant by foaming in various forms, it is usually appropriate prefabricate fittings 9 in different dimensions, cross-sections and radii of curvature, which may provide price advantages and consistent properties or quality guaranteed. From different fittings 9 then suitable for the individual channels to be produced specimens are selected and cut to predetermined final dimensions. For this purpose, especially heating wire cutting devices with adjustable linear and arcuate Thomastexi ⁇ ing are. The die segments cut to final dimensions are then joined together to form the respective molded article, e.g. glued together. The one-piece molding 8 thus formed is finished after finishing, e.g. with respect to its height on the mold bottom 3, positioned in a predetermined position and e.g.
- the cut fittings 9 can also be individually releasably fastened to the mold bottom 3 in virtually seamless joint system.
- the material and manufacturing costs of molded articles made of styrofoam 8 are so small that a single use is economically justifiable and the molded body 8 is removed from the already hardened channels even if the molded articles 8 are damaged, e.g. can be knocked out.
- Previously production of individual channels by walling by hand there are serious cost advantages of the cheap Formkö ⁇ er 8 and the possibility of automated production of the shaft bottoms with individual channels.
- the molded body 8 can also be made of hollow moldings 9, for example of plastic pipe blanks, which are connected at their butt ends thermally or by gluing together and / or with the core bottom.
- the Formgro ⁇ er 8 should have smooth smooth outer surfaces throughout, so that the molded channels are smooth-walled. When using rigid foam, the desired smooth surfaces already result from the foaming process.
- Anchored open-pore areas of such fittings 9 and also Formgro ⁇ er 8 with relatively rough surface can be covered, for example by applying cut films or liquid or pasty substances before the concrete pouring takes place.
- the covers of films or other substances or formed by release agents, such as wax or oil, can prevent caking of the concrete and facilitate the removal of the molded body 8.
- the fittings 9, 10, 14, 15 are made of inexpensive materials and can be processed by simple technical means, such as knives, saws, cutting wires.
- the assembly of the fittings 9, 10, 14, 15 to the molding 8 and also the fixing of the individual fittings 9 or the molded body 8 on the mold bottom 3 is also carried out in a technically simple manner, e.g. by gluing or by means of suitable fasteners, such as screws, dowels, etc. It is essential that all these measures be carried out by the manufacturer of the manhole bottoms on site, i. in the concrete plant, can be made.
