Abstract

An outflow which can be installed in flat supporting elements (3), especially in a sub-structural tub for a shower basin, comprising a lower part (2) that is joined to the waste-water drain below the supporting element (3) and an upper part (1) that can be joined thereto above the supporting element (3), whereby the upper part (1) of the outflow has an insertable grid cover and at least one sealable, closeable opening (15) is provided inside said grid cover, creating a passage leading to the lower side of the supporting element (3).

Description

The invention relates to a sequence for installation in flat support elements, in particular undercarriage for Shower tray, with one under the support element on one Waste water pipe connected bottom part and one from above the carrier element connectable drain top, the drain top has an insertable drain grate.

A two-part, in drain bottom and drain top structure is state of the art well known. Such a process becomes an installation in flat support elements, for example floor structure elements etc. used. At within the area the process to be provided is different from the work process proved to be advantageous, first of all the process on to attach the supporting element and then the Lay the support element with the drain. Possibly at the same time, the process is carried out on a prepared sewage pipe connected.

Alternatively, a drain lower part can also be used first below the support elements still to be installed a sewage pipe can be connected. After that the support element provided with a corresponding hole laid and then the drain top of above through the hole in the support element with the drain bottom screwed tight. Then one suitable surface sealing on the flat Support elements sealing on the drain top then applied.

To attach and align the drain base can, is in the substructure, for example a bare ceiling left a depression. adversely is that this cavity after laying the Support elements and the insertion of the drain top is no longer accessible. It is also disadvantageous that the cavity deteriorates in thermal insulation, noise protection and possibly fire protection.

DE 195 41 366.0 A1 was therefore used for a shower base with an undercarriage with such Process proposed, the undercarriage with at least a filling opening arranged adjacent to the upper drain part to provide. Through the filling opening of the undercarriage through it becomes the cavity below filled with flowable, curable material.

The disadvantage here is that the undercarriage through at least one other opening is weakened. In particular is disadvantageous that the filling opening in the Substructure pan should only be tiled after filling can. Prefabricated tiled shower bases must therefore after filling the cavity in the area of the flush opening be tiled separately, which is time-consuming and costly is and as another trade from a tiler is to be carried out. This also requires one increased sealing effort. It is also a later one Do not check the cavity after sealing possible.

The object of the invention is therefore to provide a process for Installation in flat support elements of the aforementioned Specify the type of filling and / or Revision of the to be provided under the support element Cavity is possible at any time.

This task is solved with the above Process in that in the upper part of the drain within the Drain grate area at least one tightly closable Opening is provided that a passage to creates the lower side of the carrier element.

The tightly closable one located in the drain top Opening is also after sealing the adjacent one Surface of the support elements freely accessible, since the Opening arranged in the drain grate area of the drain upper part is. One below the drain top The cavity can be removed at any time Opening must be checked or filled.

The opening is therefore protected under the drain grate or a drain cover, but is always after Remove the cover or drain grate for Revision purposes or accessible for filling. The The opening is closed, for example, with a screw cap.

Because two identical openings are diametrically opposed to each other opposite to that intended for wastewater management Element are arranged, an opening for filling in the drain area under the support element cavity are used while the second opening for ventilation and level control serves.

Alternatively, the opening is an annular space around the Waste water management element designed. For example, this is used for wastewater management provided element or sewer pipe connection via webs held on the outer drain top. The filling, especially with viscous material facilitated. In this embodiment there is also a circular shape of the drain top easily achievable.

If a lid is used to close the opening (s) tightly provided is easy access to the Guaranteed openings. In particular, in that between upper drain part and cover O-ring seals are provided, the tightness remains repeated opening of the lids.

If an insert for temporarily closing the Sequence is provided in the construction phase, the Can also be used as a screwing tool to connect the Upper drain part is formed on the lower drain part, the tools required for assembly are at hand before and at the same time it is avoided that building materials in during the construction phase.

Because the use also as a screwing tool is designed to close the opening cover, is the same use for closing the filling / inspection openings usable.

A preferred exemplary embodiment of the invention is described in detail below with reference to the accompanying drawing. It shows:

Fig. 1

a partially sectioned side view of an inventive process and

Fig. 2

a plan view of the process shown in Fig. 1.

In Fig. 1 is a flow in a partially sectioned side view installed in an opening 31 of a Carrier element 3 shown. The process instructs Drain top 1 and one with a not shown Sewage pipe connected drain bottom part 2.

The lower drain part 2 has a housing 21 on which a vertical outlet 22 for connection to the not shown sewage pipe is molded. alternative can the drain base 2 also a horizontally on Housing 21 integrally formed outlet 23 for the essential horizontal drainage. The connecting piece 23 is shown in dashed lines in FIG. 1.

In the housing 21 of the lower drain part 2 is from above the drain top 1 can be used. The drain top 1 has a concentrically insertable into the housing 21 Drain pipe 11 in which a, not shown, removable odor trap or siphon 14 is integrated. On the drain pipe 11 is on the Top of a support frame 12 is arranged.

The upper drain part 1 is preferably formed in two parts, the support frame 12 individually on the Carrier element 3 can be placed and subsequently the drain connector 11 in the frame 12 sealed in the Housing 21 of the upper drain part 2 can be screwed in.

As shown in Fig. 2 in plan view, the support frame 12 square and has one Edge web 13 for holding a drain grate or a appropriate tile insert.

When using the drain as a floor drain in shower trays is the size of the spanned by the edge web 13 Area preferred that used for floor covering Customized tile.

Within the edge web 13 are in the support frame 12th two openings 15 are provided. The openings 15 have an internal thread, screwed into the screw cap 16 are. For sealing, there is between opening 15 and screw cap 16 an O-ring 17 is provided. The Screw lid has one on the outside Screwdriver slot 18 on.

Below is the installation of an inventive Sequence based on that shown in FIGS. 1 and 2 Exemplary embodiment explained.

A drainage base suitable for the purpose 2 with vertical or horizontal outlet 22 or 23 is connected to a drain pipe, not shown. In the substructure, not shown, for example a bare ceiling or flat roof construction is a corresponding cavity for receiving the Bottom drain part 2 provided. Below are the Carrier elements 3, for example as a floor structure system or roof insulation on the surface of the Substructure applied. In the area of the process becomes a carrier element 3 with a recess 31 the drain lower part 2 relocated.

Now the support frame 12 from above Recess 31 placed in the support element 3 covering and the drain connector 11 belonging to the upper drain part 1 through the circular opening in the support frame 12 in the Drain housing 21 of below the support element 3 arranged drain bottom part 2 screwed tight. A screwing tool, not shown, serves as the screwing tool Use the process in reverse orientation covers overlapping, for example in the Construction phase with a contamination of the drain Avoid building materials.

As an alternative to the above, this can be done with a Recess 31 for the drain element 3 be provided with the drain before installation. The lower drain part 2 on the underside of the Support element 3 held and the upper drain part 1 through the recess 31 into the lower drain part 2 screwed. Below is the process provided carrier element 3, in particular with a horizontal outlet 23 to one proper connection to the disposal line worry is. With a vertical outlet 22 cavity provided in the bare ceiling preferred as Breakthrough, with which from an underlying room Waste water pipe installation after laying the Carrier elements is possible.

When used as a floor drain is in the drain socket 11 a removable odor trap or Siphon 14 inserted.

To the cavity formed under the drain to be able to control or fill them Openings 15 by unscrewing the screw cap 16 open. Also serves as a screwing tool the use of a corresponding screwdriver-like element for engaging in the Screw lid 16 has formed slot 18.

When filling with flowable or free-flowing material, for example insulation, both are preferred Openings 15 opened and the one opening as a filling opening for filling the material and the other opening for monitoring the fill level and venting used.

After filling or checking the openings 15 by screwing on the screw cap 16 sealed again by means of the insert. Then the drain grate can be put back into the Edge web 13 are inserted.

There is a revision or filling of the cavity at any time regardless of the other surface sealing, for example, tiling. The surfaces immediately adjacent to the drain can therefore be completed throughout.
