Aflobsbronde ifolge disse publikationer har nok separate indsatse, men brondene har desuden en lav gennemstromnings-kapacitet i forhold til deres ydermâl.Drainage wells according to these publications probably have separate inserts, but the wells also have a low flow capacity in relation to their outer dimensions.

2Q Ved kendte gulvbronde af den i indledningen angivne art er det nemlig vanskeligt under bibeholdelse af bestemte ydermâl pâ enkel mâde at opnâ stor gennemstromnings-kapacitet.2Q With known floor wells of the type specified in the introduction, it is difficult to achieve a large flow capacity in a simple manner while maintaining certain external dimensions.

2^ Formâlet med den foreliggende opfindelse er derfor at eliminere dette problem, det vil sige at afstedkomme stor gennemstromningskapacitet uden at bronden derved bliver komplicered.The object of the present invention is therefore to eliminate this problem, i.e. to produce large flow capacity without thereby complicating the well.

g. Dette opnâs ifolge opfindelsen ved at skærmvasggen er udformet som en foroven âben forlængelse af udlobsroret og rager ind i en del af indlobsdelen, som der er bredere end forlængelsen og ligger bag vandlâstungen.g. This is achieved according to the invention in that the screen wall is designed as an upper open extension of the outlet pipe and projects into a part of the inlet part which is wider than the extension and lies behind the water lock tongue.

^ Herved bliver skærmvasggens ovre kant. væsentligt længere end udlobsrorets diameter og vandet kan passere ind i aflobs-roret via denne længere kant.^ This will be the upper edge of the screen wall. significantly longer than the diameter of the outlet pipe and the water can pass into the drain pipe via this longer edge.

Dette er en stromningsteknisk fordel.This is a flow engineering advantage.

Ved at indsatsen er monterbart anordnet kan den loftes ud af br0nden og derigennem kan man let komme ind i lommen bagved væggen og ogsâ ind i afl0bsr0ret nærmest lommen for rengoring af disse omrâder.By the insert being mountably arranged, it can be ventilated out of the well and through it one can easily get into the pocket behind the wall and also into the drain pipe closest to the pocket for cleaning these areas.

0get gennemstromningskapacitet opnâs ogsâ ved at skærm-væggen ifolge krav 2 har i hovedsagen samme eller storre 10 bredde end udlobsroret.Increased flow capacity is also obtained by the screen wall according to claim 2 having substantially the same or greater width than the outlet pipe.

Ifolge krav 3 er skærmvæggen forbundet med en sâdân del af indlobsdelen som ligger pâ et lavere niveau end udlobs-rorets laveste del til dannelse af en lomme, hvis laveste del ligger pâ et lavere niveau end udlobsrorets laveste del. Herved hindres i stor udstrækning at vand strommer retur ind i indlobsdelen.According to claim 3, the screen wall is connected to such a part of the inlet part which is at a lower level than the lowest part of the outlet pipe to form a pocket, the lower part of which is at a lower level than the lowest part of the outlet pipe. This largely prevents water from flowing back into the inlet part.

For at lette fremstillingen af skærmvæggen udformes denne 20 ifolge krav 4 med dels to med hinanden og i hovedsagen ogsâ . med udlobsrorets længdeakse parallelle vægge og dels med en disse parallelle vægge forbindende endevæg.In order to facilitate the manufacture of the screen wall, it is designed according to claim 4 with partly two with each other and mainly also. with the longitudinal axis of the outlet pipe parallel walls and partly with an end wall connecting these parallel walls.

Opfindelsen skal i det folgende forklares nærmcre i for-25 bindelse med tegningen, hvor fig. 1 viser et snit gennem en aflobsbrond med en anordning ifolge opfindelsen, 30 fig. 2 et snit gennem en alternativ udforelsesform for aflobsbronden, fig. 3 et snit langs linien III - III i fig. 2, og fig. 4 og 5 snit gennem partier af aflobsbronde med for-skelligtformede sæder og snapfatninger.The invention will be explained in more detail below in connection with the drawing, in which fig. 1 shows a section through a drain well with a device according to the invention, fig. 2 is a section through an alternative embodiment of the drain well, FIG. 3 is a section along the line III - III in fig. 2, and FIG. 4 and 5 sections through portions of drain wells with differently shaped seats and snap sockets.

Den pâ tegningen viste afl0bsbr0nd har en indlobsdell med mindst et fra denne siderettet udlobsror 2. I indlobsdelen 1 er aftageligt anbragt en indsats 3, som dels kan optages, dels omfatter en vandlâstunge 4 og har et indl0bsparti 5 5 med mindst en 0vre indlobsâbning 6 og mindst en nedre gennemstr0mningsâbning 7, der foroven er begrænset af vand-lâstungens 4 underkant 8.The drain well shown in the drawing has an inlet part with at least one outlet pipe 2 directed from this side. In the inlet part 1 an insert 3 is removably arranged, which can partly be accommodated, partly comprises a water trap tongue 4 and has an inlet portion 5 with at least one upper inlet opening 6 and at least one lower flow opening 7, which is limited at the top by the lower edge 8 of the water-lock tongue 4.

For ved br0nden med den nævnte indsats 3 dels at kunne rense udlobsroret 2 effektivt, dels kunne opnâ lav total-hojde pâ bronden under bibeholdelse af den krævede vandlâs-hojde og desuden opnâ bedst mulig gennemstromningseffekt og trykvariationseffekt, er indsatsens 3 gennemstromnings-âbning 7 for neden begrænset af et vægparti 9 af en med ^ vandlâstungen 4 forbunden og indsatsens 3 indlobsparti 5 fra indlobsdelen 1 afskærmende væg 10, hvilket vægparti 9 er beliggende pâ et lavere niveau 11 end udlobsrorets 2 laveste del 12.In order to be able to clean the outlet pipe 2 efficiently at the well with the said insert 3, partly to achieve a low total height of the well while maintaining the required water trap height and also to achieve the best possible flow effect and pressure variation effect, the flow opening 7 of the insert 3 is for below limited by a wall portion 9 of a wall 10 connected to the water supply tongue 4 and the inlet portion 5 of the insert 3 from the inlet part 1, which wall portion 9 is located at a lower level 11 than the lowest part 12 of the outlet pipe 2.

7 Ω υ Strommngen gennem indsatsen og skærmens 13 afskærmnmg mod tilbagelobende vand kan gores effektiv ved, at det skærm-dannende vægparti 13 udgores af en under vandlâstungen 4 beliggende, med en udstromningsâbning 14 forsynet del af en skâlformet ydervæg af indsatsen 3.7 υ υ The flow through the insert and the shield 13 of the screen 13 against refluxing water can be made effective in that the screen-forming wall portion 13 consists of a part of a shell-shaped outer wall of the insert 3 provided under the water trap tongue 4, provided with an outflow opening 14.

25 Særlig god afskærmning mod tilbagelobende vand kan opnâs ved, at det skærmdannende vægparti 13 i det mindste for neden i udlobsrorets 2 munding hælder til dannelse af en lomme 15 nedenfor indsatsens 3 udstromningsâbning 14.Particularly good shielding against refluxing water can be obtained by the screen-forming wall portion 13 sloping at least below the mouth of the outlet pipe 2 to form a pocket 15 below the outflow opening 14 of the insert 3.

30 I visse tilfælde kan det ud fra stromnings-, fremstillings-og stabilitetssynspunkter være fordelagtigt at lade indsatsens 3 vægparti 9 udmunde ved en i indlobsdelen 1 ind-gâende skærmvæg 16, som afskærmer udlobsrorets 2 indre med 35 undtagelse af en udstromningsâbning 17, som tillader ud-stromning til udlobsrorets 2 ovre del.In certain cases, from a flow, manufacturing and stability point of view, it may be advantageous to have the wall portion 9 of the insert 3 open at a screen wall 16 entering the inlet part 1, which shields the interior of the outlet pipe 2 with the exception of an outflow opening 17 which allows outflow to the upper part of the outlet pipe 2.

For ved denne udforelsesform at opnâ den bedst mulige skærmeffekt mod tilbagelobende vand, kan skærmvæggen 16 være forbundet med en del 18 af indlobsdelen 1, som ligger pâ et lavere niveau end udlobsrorets 2 laveste del 12 til 5 dannelse af en lomme 19, hvis laveste del ligger pâ et lavere niveau end udlobsrorets 2 laveste del 12.In order to obtain in this embodiment the best possible screen effect against refluxing water, the screen wall 16 can be connected to a part 18 of the inlet part 1, which is at a lower level than the lowest part 12 of the outlet pipe 2 to 5 forming a pocket 19, the lowest part of which is at a lower level than the lowest part 12 of the outlet pipe 2.

Den i indlobsdelen 1 indgaende skærmvæg 16 skyder som en foroven âbèn forlængelse af udlobsroret 2 ind i en sâdan 1® del af indlobsdelen 1, som dels er bredere end for-længelsen, dels er beliggende bag vandlâstungen 4. Som folge heraf kan skærmvæggen 16 ligge nær vandlâstungen 4 uden at disse dele danner en stromningseffekten væsentlig nedsættende drovling. Af fremstillingstekniske ârsager er det fordelagtigt at udforme forlængelsen, sâledes at den dels har to med hinanden og i det væsentlige ogsâ med udlobsrorets 2 længdeakse parallelle vægge 20 og dels udviser en disse parallelle vægge 20 forbindende endevæg 21.The screen wall 16 entering the inlet part 1 projects as an upper leg extension of the outlet pipe 2 into such a 1® part of the inlet part 1, which is partly wider than the extension, partly located behind the water load tongue 4. As a result, the screen wall 16 can lie near the water load tongue 4 without these parts forming a flow effect significantly reducing drooling. For technical reasons of manufacture, it is advantageous to design the extension so that it has two parallel walls 20 with each other and substantially also with the longitudinal axis of the outlet pipe 2 and partly has an end wall 21 connecting these parallel walls 20.

30 Indsatsen 3 kan fastholdes i indlobsdelen 1 pâ en enkel og formâlstjenlig mâde, ved at indlobsdelen 1 for oven har et sæde 23, mod hvilket et ovre parti 24 af indsatsen 3 ligger an via et tætningsorgan 25.The insert 3 can be held in the inlet part 1 in a simple and expedient manner, in that the inlet part 1 above has a seat 23, against which an upper portion 24 of the insert 3 abuts via a sealing member 25.

35 Indlobsdelens 1 sæde 23 for indsatsen kan ligge nærmere centrum af indlobsdelens 1 ovre âbning end et andet i indlobsdelen 1 indgâende sæde 26, som skal udgore anlægs-The seat 23 of the inlet part 1 for the insert may be closer to the center of the upper opening of the inlet part 1 than another seat 26 included in the inlet part 1, which is to form a system.
