DE4314222C1 - Wall lead-through on a concrete vessel - Google Patents

Abstract

Concrete vessels, for example separating vessels in sewerage technology, require wall lead-throughs which, depending on the application purpose, have to have different diameters and arrangements. This necessitates an extremely large number of components to be kept in stock. In order to reduce the number of types of vessels kept in stock, the vessels (1) have wall openings (2) for the insertion of insert discs (3), in which the actual lead-through openings (4) are arranged. For each nominal size, only one single type of vessel is thus necessary, it being possible, depending on the requirements, to adjust said vessel type to the given application purpose by means of different insert discs. <IMAGE>

Description

The invention relates to a wall bushing according to the preamble of Claim 1.

A wall bushing of this type can be found in DE 43 08 942 A1. This has a sleeve or insert in the wall opening, the thickness of which Corresponds to the wall thickness of the container and inserted from the outside into the wall opening and glued there. It is a very flat element, which only has the task of the actual lead-through opening within the wall opening to create for the connecting piece.

The many different tasks in separation technology require one large number of container designs. For the same pot size, depending on the task, different diameters and heights of the Inlets and outlets. Before the pots are made, the inlet and outlet sleeves must be can be inserted into the mold according to the design. This is with one Not inconsiderable effort, since the drawing dimensions for each small series checked and the adjustments have to be adjusted. This approach also harbors the risk of errors caused by incorrectly chosen drawings gene, reading errors, measurement errors u. a., which causes defects to unusability can arise.

In addition, the resulting container can only be used for a very specific purpose use. Therefore, a complex manufacturing planning and a large one Stock required to be able to fulfill orders quickly. On Changes in the market cannot be reacted to flexibly.

The invention has for its object, wall bushings on the container mentioned type without creating complex manufacturing planning. Existing Container types should be used for a wide variety of purposes with those for them Wall bushings required for each purpose.

According to the invention, the wall bushing in the in the characteristic of Claim 1 created way.

Instead of precisely defined lead-through openings in the container wall, there are larger ones Wall openings formed in the container wall, which the insert discs with the integrated through openings. The wall openings are circular and flaring outwards. You have execution for everyone types of a container size the same positions. So there is one container size only one version, and now there is only one instead of several small series Series before. An insert disc is placed in the wall opening. This disc has outside the shape of a truncated cone and has one centrally or eccentrically circular opening required for pipe penetration. The truncated cone is like this designed so that it fits exactly into the conical wall opening. Using an adhesive the pane is permanently and tightly connected to the concrete wall. The design the container variants are therefore made by choosing the insert disc. Depending on the location the opening of the pane results in a different inlet or outlet height and depending on the Opening diameter another nominal size.

This will make the decision about the container variant away from the Container production shifted towards the selection of slices and their installation. this has following advantages:

• - The container production takes place in a rational large series.
• - There is no longer a committee due to incorrectly installed inlets and outlets.
• - The inventory of containers can be reduced. A big one must now Number of slices in stock. Due to the small dimensions, the Warehousing but not very expensive.  
• - Furthermore, adjustments to new market requirements Constructions are quick and inexpensive.

Further design options for the insert disc are in the subclaims contain:

• - The discs have two locking cams on the outside and the wall opening appropriate grooves so that the correct positioning during assembly is ensured.
• - The disc is made on the inside with one or more grooves for sealing rings or a seal (e.g. lip seal) is integrated.
• - The eccentricity of the disc opening is so with the height of the Wall opening matched that two required with a washer Feedthrough heights are achievable depending on the eccentric Feed-through opening is up or down from the center. In order to is a reduction in the number of disc variants and savings in production and storage of the discs achieved.
• - The designations of the Intended use, so that when installing the separator type on the in the container-facing end face and assembly errors be prevented. In the case of eccentric feedthrough openings, this is Label above valid.
• - Due to production reasons, the panes are placed on the panes pointing out of the container The faces "inlet" or "outlet" and the Manufacturer's name coined, so that inlet and outlet and manufacturer no longer must be written separately on the container and also assembly errors be prevented.
• - Containers with more than two openings and insert discs without Opening (as a sealing disc) made, so that even custom-made products can be delivered at short notice without much additional effort.

The accompanying drawing shows exemplary embodiments of the invention. It shows

Fig. 2 A insert disc in section and in the view,

Fig. 3 Multiple use disks in section with different passage openings,

The container 1 has circular wall openings 2 that widen conically outwards in its walls. Insert disks 3 , which with the outer shape of a truncated cone fit exactly into the wall openings 2 , have centrally or eccentrically arranged through openings 4 of the desired size. An insert disc 3 with an eccentric through-opening 4 can be used for an upper or lower connection of the connecting piece, depending on its installation. If no connecting piece is provided, the opening can be closed by an insert disk designed as a blind plate. Locking cams 5 on the insert disks 3 engage in corresponding recesses on the wall of the container 1 and thus ensure a fixation. Sealing elements 7 are to be inserted into circumferential grooves 6 at the through openings 4 . Impressions about the type of container, the type of connection or the manufacturer on the outside of the insert discs 3 enable a reliable assignment of the parts to the corresponding type of container.
