DESCRIPTION:
BRIEF SUMMARY
The invention relates to a discharge fitting for a tiled floor having a sink made of plastics material and being provided with a headpiece carrying a grate. The sink (gully) is cast in an integral cylinder of a plate made of concrete, preferably polyester concrete. At the surface of the plates, there are formed faces leading from the plate edges to the gully. A discharge fitting of this kind is known from German Offenlegungsschrift No. 36 27 807.
In such a discharge fitting, gully and concrete plate are a prefabricated unit which may be placed on the finished raw concrete. Recesses are formed in the concrete for the purpose of receiving the gully and the connecting pipes. Plaster floor may be applied around the plate on the concrete up to the level of the plate edge. This has as a result an automatically correct height adjustment of the gully and the plate surfaces inclined towards the gully present a geometrically exact foundation for a tile flooring having the required inclination.
The subject matter of the present invention is a further development of a discharge fitting of the kind described as regards a mechanically solid connection between the plate and the plaster floor being adjacent thereto.
This object is attained by the features of the main claim. The subclaims contain preferred embodiments.
In such a discharge fitting, a lattice of glass fibers is cast integral with the concrete plate during manufacture and is placed on the floor surrounding the plate when being applied to the floor. When the mortar or the adhesive material for the tiles has been applied, a tension-proof connection is achieved between the plate and the surroundings, because the lattice of glass fiber is bound in the compound material and such represents the foundation for the tile flooring. The formation of cracks in the joints is in particular avoided thereby.
According to a preferred embodiment of the invention, the concrete plate is continued at all sides by reinforcement wire meshes which form, after the bedding works, the connection between the concrete plate and the plaster floor. By the reinforcement wire meshes, a rigid connection in particular between the discharge fitting and the surrounding regions is produced. Thus, a shifting of the discharge fitting in particular in the case of unskilled bedding works is avoided. Preferably, four reinforcement wire meshes arranged cross-like are used which, during production of the concrete plate, may be placed laterally into a two-piece casting mold.
The anchoring of the reinforcement wire meshes with the discharge fitting may additionally be improved in that the reinforcement wire meshes are directly welded to the sink, provided that the latter consists of gray cast iron as known per se.
In the following text, the present invention is described in closer detail by means of embodiments and with reference to the accompanying drawings. Therein is:
FIG. 1 a plan view of the discharge fitting according to the invention;
FIG. 2 a vertical sectional view of the discharge fitting;
FIG. 3 a vertical sectional view of the discharge fitting according to another embodiment;
FIG. 4 a section on the line A-B of FIG. 3.
In this discharge fitting, a sink 35 (gully) made of plastics material and known per se is cast in a plate 30 of concrete, preferably polyester concrete. The concrete plate is square in plan view and bas faces 33 starting from the sides and being inclined towards the gully. The gully comprises a vertical discharge pipe 37. In the region of transition, the plate 30 is reinforced by an integrally formed cylinder 34. Besides, the gully may comprise odor sealing elements in a manner known per se. It has a headpiece 38 carrying a grate 39.
The sides of the square are extended all around by a lattice 40 of glass fibers, a solid connection being made between said lattice and the plate.
The discharge fitting is inserted in a corresponding recess of the local concrete. The discharge pipe is connected to the stationary discharge pipe line. The lattice lies on the concrete floor or the pl
