Definitions
- the invention relates to a negative mold of at least part of a channel of a monolithic shaft bottom forming molding according to the preamble of claim 1.
- Manhole bottoms provide the bottom seal of generally vertical manholes that provide access to sewer systems, such as sewers, and underground pipe systems. Such wells are often located in interfaces of conduits, i. at channel branches or outlets and junctions of secondary channels, etc.
- the bottom of such shafts forming shaft bottoms are pot-shaped structures with a relatively thick-walled dense bottom and a mostly cylindrical side wall, in which connection openings for the tubes and / or channels are formed.
- connection openings for the tubes and / or channels are formed in the shaft bottom run open at the top, referred to as channels channels of mostly semi-circular or approximately U-shaped cross section between the respective provided in the side wall of a shaft bottom connection openings.
- the channels In order to ensure a jam-free flow of the frequently contaminated with significant amounts of large-scale solids liquids, the channels have a certain slope and the bottom of the shaft called a berm appearance of low slope.
- the shafts are constructed of standardized individual rings, the shaft bottoms are individually designed components which differ from one another with regard to the positioning of the connection openings acting as inlets and outlets, the cross-sectional shape of the channels and the pipes to be connected.
- only high-quality, liquid-tight concrete may be used for the production of manhole bases and in particular their channels.
- the profile pieces can not only frontally, but also in the area of the tread surface of the mold surface facing attachment surface in any way with the help of a heating wire in a relatively simple manner cut.
- the feed of the heating wire can be controlled mechanically depending on the respective required shape.
- the invention aims at a further development of these known fittings, in such a way that the fittings can be easily removed after solidification of the concrete.
- a simple production of a shaped piece is ensured when the cavity extends, starting from the base surface into the interior of the shaped body tapering.
- a sufficient strength of a fitting - even if this must be reduced according to the local conditions of the shaft floor - results from the fact that several longitudinally of the fitting successive cavities are provided, which are separated from each other by extending substantially to the base intermediate walls.
- a particularly expedient embodiment of a shaped piece is characterized in that it extends with its longitudinal extension over a quarter circle arc and that three cavities arranged one behind the other in the longitudinal direction are arranged uniformly distributed.
- a simple orientation aid in assembling a plurality of shaped pieces to a shaped body or when providing connections results from the fact that a center mark in the form of a V-shaped recess or V-shaped elevation is provided on a shaped piece at its arcuate vertex.
- a shaped piece is formed such that the base of the mold with an arcuate recess extending over the entire longitudinal extent a molding extends, is provided, wherein the curvature of the arcuate recess corresponds to the curvature of the arcuate crest of the molding.
- the shaped pieces In order to obtain a smooth concrete surface, it is expedient for the shaped pieces to be closed-pored on the outer surface, which may be e.g. can be achieved in hard foam plastic characterized in that the molds are polished for the production of the fittings or are provided with a special vapor deposition.
- a simple mounting possibility of a molded piece or of a shaped body consisting of two or more moldings on a mold bottom of a bottom mold is obtained if a permanent magnet arranged approximately in alignment with the base surface is fastened in at least one cavity, wherein preferably the permanent magnet is fastened to a holder, which is fastened by means of a fastening means on a side wall of the molding.
- a particularly simple assembly of two or more fittings can be achieved by using a mounting plate, which is characterized in that the mounting plate has a diameter which is slightly smaller than the diameter of a mold bottom of the negative mold of the shaft bottom, wherein the mounting plate with at least about a portion of the circumference and circumferentially uniformly distributed recesses is provided, are inserted into the bolts, which are insertable in recesses of the end and / or intermediate walls of a molding, which recesses of the fitting emanate from the base surface.
- a bolt which can be inserted into a recess of an end and / or intermediate wall of a shaped piece, is rigidly arranged at one point of the circumference of the mounting plate.
- the recesses of the mounting plate are formed as arranged in the radial direction slots.
- FIG. 1 a partially sectioned plan view of a shaped piece in a bent embodiment
- the Fig. 2 an end view in the direction of arrow II
- the 3 and 4 Illustrate sections along lines III-III and IV-IV.
- Fig. 5 shows the top view of a rectilinear fitting
- Fig. 6 a section according to the line VI-VI of Fig. 7 having a section along the line VII-VII of Fig. 5 shows.
- Fig. 8 gives a detail of a fitting in section again
- Fig. 9 illustrates a composite of several moldings molded body which is mounted on a mounting plate.
- the FIGS. 10, 11 and 12 illustrate a further embodiment of a shaped piece in oblique, in plan view and in sectional view on an enlarged scale.
- FIG. 1 illustrated molding 1 made of foam, in particular rigid foam plastic or thermoplastic material, such as EPS, extends over a quarter circle and has an approximately U-shaped cross-section, wherein the legs of the U-forming sides 2 diverge from the open end of the U.
- the molding 1 has three in the longitudinal extent of the molding 1 successively arranged cavities 3, between which intermediate walls 4 are provided, wherein the ends of the molding 1 are closed by end walls 5.
- These cavities 3 are open towards the base surface 6 of the molded piece 1 and likewise have side walls 7 diverging towards the open side, so that the production, in particular the removal from a production mold, is simplified.
- a mark 8 preferably formed as a groove or as a small elevation, whereby a central attachment of terminals is facilitated to the fitting 1.
- a further marking may also be provided vertically on the outside of the molding 1 in order to allow an accurate cutting of any protrusion on the front side.
- the fitting 1 is provided with arcuate recesses 9, which have the same curvature as the apex portion of the molding 1, so that the fittings 1 are stackable without any pressure points that could cause a deformation of a fitting 1.
- the fittings 1 are designed closed pores on the outside in contact with concrete in contact with the outside. This can be effected, for example, by polishing or steaming the manufacturing molds, when the shaped pieces are formed of hard foam plastic or the like.
- Shaped piece 10 has a rectilinear longitudinal extension and is also arranged with successively arranged cavities 3, which extend from the base 6 of the fitting 10 upwards, ie in the direction of the arcuate apex portion of the U-shaped cross section of the fitting 10, as well widening conically towards the outside.
- the end portions of this fitting 10 are end walls 5 - greater thickness 11 - equipped as the Partitions 4, so that an arcuate trimming or trimming with regard to a slope to be maintained, as for example for the end walls 5 in Fig. 7A is possible.
- the second intermediate wall 4 ' is also thick-walled in the straight fitting 10, so that when separating the first cavity 3, this partition can also serve as an end wall.
- Fig. 8 which illustrates a cross section through a fitting, is shown how a permanent magnet 12 by means of an angle bracket 13 and a special screw 14 on the fitting in the cavity 3 can be fastened.
- This permanent magnet 12 reliably holds the molding on a magnetic mold bottom of a bottom mold, so that the molding can not float when poured with concrete.
- the composition of Mehererer fittings 1 and / or 10 to a shaped body 15 is, as this Fig. 9 illustrated facilitated by a mounting plate 16.
- This mounting plate has at one point a fixedly arranged bolt 17, which in a corresponding recess 18 (see. Fig. 7 ) of a fitting 1 - for example, with a diameter of 12 mm - can be used when this fitting 1 is placed on the mounting plate 16.
- the mounting plate 16 is further equipped at least over an angle of 180 ° close to the circumference with recesses 19, in the bolts 20 which are provided in fittings, ie in recesses 18 of the fittings 1 and 10 were introduced, can be used, so that the other Fitting 1 or 10 can take a precise position relative to the arranged on the mounting plate previously fixed bolts 17 fitting.
- the bolts 20, which suitably have a rectangular approach at the bottom are to be arranged according to the required angles in the slots 19 at the inlet and inlet sides.
- the already glued main chute 21 is attached.
- the sub-channel (indicated by the arrow 22) is adhered to the main chute 21.
- the bolt 20 is placed first, the sub-channel (which is already adapted according to the main channel) centered on the bolt and against pushed the main channel (the bolt is movable in the slot 19 in its longitudinal direction).
- the thus assembled channel can now be cut round.
- the molded pieces 15 and / or 10 glued together from the moldings 15 can be fitted after the circular cutting with the described permanent magnet 12.
- the angle bracket 13 is pressed on an inner side 7 of a cavity 3 first in the wall (eg made of polystyrene) and then screwed with the special screw 14.
- the magnet 12 on the underside neither looking forward nor back it makes sense to use a non-magnetic bar to help to press the angle bracket 13 (with already mounted magnet 12) in the Styrofoam.
- the molded body 1 or 10 is placed on the mold bottom of a bottom mold, wherein it is aligned with the bolt which is attached to the outlet side. At the inflows and outlets, the channel is fixed by means of retaining strips, which prevent floating.
- FIGS. 10, 11 and 12 illustrated embodiment of a molded piece this is provided in its apex area with recesses V, are formed by the increases in the channel.
- the depressions V have a depth of 3 to 5 mm and they are arranged with their longitudinal axis at an angle of about 45 ° relative to the longitudinal axis of the shaped piece (according to the plan view Fig. 11 ).
