Technical field

The invention describes a floor-embedded drain intended for internal or possibly external use where waste-water needs to be conducted off of the floor. The canal ¹ is placed on a floor with tiles or any other type of, pavement.

Background art

The drainage channels and intakes are covered with grids of various shapes and structures. These are plates with holes inside (an intake lattice put atop the drain) or a body consisting of a perforated plate and side walls or legs inserted into the channel withioutlet. Water flows into the collecting pipeline through the holes. Drains are installed inside buildings as well as on outer surfaces, namely- car, parks and roads.-They collect waste-wateji,Water from outer surfaces and other liquidsuThe perforated slate, is^made of various materials, commonly steel, non _r ferrous metals, plastic etc. and using different manufacturing methods - molding sheet metal, casting, welding, injection etc. The plate is usually flat or with little bumps which prevent sliding.

The drain is accountable for several functions. Its task is to efficiently drain away water which is not to remain at the canal. Contemporarily, the aestethics properties, especially of interior drains, are taken into consideration as well. For the application of.dra _. ins,, important aspects are also its manufacturing costs and additional exp^nse^s on its installation,- including the intake. These requirements are ,bei.ng.met by many de.signeϊs and their designs are protected by a number of patents or utility designs. Howevex, ja _x solution with its main ¹ construction target being the easy installation of the drain tjod.ty jsyet to be revealed. At present, the drain body firstly has tpi be ^" properly aligned,, theriiparirally embedded in concrete and overlaid with a finishing material ip:the,form of tiles, plates ^, etc! f, insulation is used„ (water-proofing or heat insulation), the task of embedding in.concretfc must be split, insulation applied, the process of embedding continued thereafter and the floor finished.

Dislosure of invention

The disadvantage discussed above is largely eliminated with a drain where the body of which is given an opening and a protective grid, as described by the invention, the essence of which is that the drain body and the surrounding surface finish may be laid out at the same time . Also, the area of the drain's opening equals or exceeds the area of the opening of the intake. Finally, theiheightM of <tbe φain sbody lequaKor apprø^imatesftoihe _t height h2 of the surrounding finish. The invention's advantage is the setup of the drain in relation to the paving or tiling finish leveled against it. The _; installation becomes easy and quick thanks to the very low height of the drainage, approximately matching the height of the floor's finishing layer. When the inlet has been embedded in concrete, the surface finish may begin to be laid down together with the* drainage. Another significant advantage being that the position of the drainage body is not pre-set before the floor's finishing, basically meaning that the drainage may be laid. out with-the surface fintøhjiot having to be cutT*hough this versatility is_n_ot * boundless.Jt provides enough options for the convenient placement of the drainage io _t β|l directions, The new drainage design accelerates the installation noticeably whjleiretaining all drainage features.

Brief description of the drawing

A drain based ,oκι the invention is demonstrated in the drawing^yvhere Fϊg.1 representsja . crossrsection of atflopr with emb,eddec| drainage, Fig^ .the.drjaijj) body and Fig«.3,^detail of the intake.

Example of carnving-outitheinvention!-. The drain channel 2 with a covering grid 3 is of rectangular shape and has an opening 2a at its bottom. The drain body 2 is placed above the intake 1 with a drainage pipeline 4, which is in the area of the opening secured with a circular pressure sealing 5 due to the possibility of waste-water leaking into the intake's 1 neck area. The placement of the drain body 2 is leveled with the surface finish 6 surrounding it. Height M_ of the drain body equals height h2 of the finish 6 lining the body. The area of the drain's 2 opening 2a equals or exceeds the area of the opening Ia of the intake ±. When appropriate, an insulation layer 7Js placed under the finish 6 and partially under the drain body 2, glued 8 to the edges of the intake 1.

Upon the embedding of the intake 1 in concrete, the drain can only be layed simultaneously

S

with the finish 6. An opening 2a in the drain body 2 larger than the intake's 1 opening Ia allows for a deviation of the drain body 2 of up to 20mm on the x and y axes relative to the intake 1_axis. Where insulation is used* the drain is put straight onto the insulation layer 7 along with the surface finish.

In case height hj. of the drain body 2 does not match height h2'of the finish 6, the drain body 2 is underlaid with a layer of glue or othersuitable material.
