Den kendte teknikThe prior art

Kloaksystemer er opbygget af rørledninger og brønde, som er udviklet til 20 bortledning af kloak-, spilde-, og regnvand fra veje, pladser, marker, boliger og industribygninger. Brøndene har til formål at samle eller ændre retningen af rørledningerne, ligesom de giver mulighed for inspektion af løbet i en rørledning og for at igangsætte rensning af rørledningssystemet, hvis det måtte være påkrævet.Sewerage systems are made up of pipelines and wells, which have been developed for 20 drainage of sewage, wastewater and rainwater from roads, squares, fields, homes and industrial buildings. The wells are intended to collect or change the direction of the pipelines, as well as to allow inspection of the barrel in a pipeline and to initiate purification of the pipeline system, if required.

Brønde fremstilles i mange størrelser og består af en brøndbund, én eller flere brøndringe, en kegle og et dæksel. Størrelsen på brøndringe, kegler og dæksler er standardiserede, hvorfor disse komponenter typisk er lagervarer. Brøndbunden skal derimod fremstilles individuelt til hver brønd.Wells are made in many sizes and consist of a well bottom, one or more well rings, a cone and a cover. The size of well rings, cones and covers are standardized, which is why these components are typically stock items. The well bottom, on the other hand, must be made individually for each well.

Der findes to typer brøndbunde til henholdsvis en sandfangsbrønd og en banketbrønd.There are two types of well bottoms for a sand trap and a banquet well, respectively.

2 DK 176847 B12 DK 176847 B1

Bunden til en sandfangsbrønd fremstilles af en brøndring, hvori der er støbt en plan bund. Rørtilslutningerne er typisk anbragt en halv meter over bunden, så sand og andre partikler kan bundfældes. Rørtilslutningernes placering i brøndringen bestemmes af rørledningernes forløb og retning.The bottom of a sand trap is made of a well ring in which a flat bottom is cast. The pipe connections are typically placed half a meter above the bottom so that sand and other particles can be deposited. The location of the pipe connections in the well ring is determined by the course and direction of the pipelines.

Bunden til en banketbrønd fremstilles af en brøndring, hvori der er støbt en bund. Bunden er udstyret med bundløb mellem rørtilslutningsåbningerne for at sikre det hydrauliske flow gennem brønden. Bundløbet kan være forgrenet. Mellem bundløbene og brøndens vægge er der støbt banketter med en 10 hældning, som leder partikler, slam og andet vandigt affald ned mod bund-løbene, så der ikke opstår ophobninger af affald i brøndbunden, og så at rotter ikke kan etablere reder.The bottom of a banquet well is made of a well ring in which a bottom is cast. The bottom is equipped with a bottom flow between the pipe connection openings to ensure the hydraulic flow through the well. The bottom run may be branched. Between the bottom trenches and the well walls there are casts with a 10 slope, which directs particles, sludge and other aqueous waste down towards the bottom troughs, so that no accumulation of trash debris occurs and that rats cannot establish nests.

Brøndbunden til en banketbrønd fremstilles individuelt til en specifik 15 opgave. Den samlede arbejdstid andrager mellem 4 og 6 timer fordelt over 3 dage. Processen er langsom, hvilket skyldes den individuelle opbygning.The well bottom for a banquet well is individually prepared for a specific task. The total working time is between 4 and 6 hours, spread over 3 days. The process is slow, which is due to the individual structure.

En brøndring tages fra lageret og der bores huller til rørtilslutninger, hvorefter bunden støbes og sættes til hærdning i mindst 12 timer. Støbning af bundløb og banketter udføres derefter som håndarbejde. Da brøndringene 20 typisk er fra 50 til 100 cm høje, giver det en meget uhensigtsmæssig arbejdsstilling. Bundløbet og banketterne bygges op i grovbeton, som senere finpudses. Dette arbejde foregår således foroverbøjet ned i brøndbunden og udgør en stor belastning for den person, der udfører arbejdet.A well ring is taken from the warehouse and holes are drilled for pipe connections, after which the bottom is cast and set to cure for at least 12 hours. Bottom casting and banqueting are then carried out as handwork. Since the well rings 20 are typically 50 to 100 cm high, this gives a very inappropriate working position. The bottom run and banquets are built up in coarse concrete, which is later refined. This work thus takes place bent over into the well floor and poses a great burden to the person performing the work.

25 Der er gjort forsøg på at afhjælpe denne uheldige fremstillingsmetode ved at standardisere brøndbundene, således at de kan fremstilles i forme med forskellige formkerner og lagerføres i et antal varianter Imidlertid har det vist sig, at de projekterende virksomheder ofte kræver løsninger, der ikke kan opfyldes af et standardiseret produkt. Såvel koter som vinkler skrider 30 under projekteringsprocessen og senere under monteringen, således at det ender med, at der skal fremstilles en individuel brønd.25 Attempts have been made to remedy this unfortunate manufacturing method by standardizing the well bottoms so that they can be made in molds with different mold cores and stocked in a number of variants. However, it has been found that the design companies often require solutions that cannot be met. of a standardized product. Both scopes and angles progress 30 during the design process and later during assembly so that an individual well must be produced.

Ofte gives ordren til levering af en individuel brønd så sent, at de tre dage, der skal anvendes til fremstillingen, medfører forsinkelser i byggeriet.Often, the order for the delivery of an individual well is given so late that the three days to be used for manufacturing cause delays in construction.

Beskrivelse af udførelseseksemplerne I det følgende vil udførelseseksempler vist på fig. 1-5 blive beskrevet.DESCRIPTION OF THE EMBODIMENTS In the following, embodiment examples shown in FIG. 1-5 are described.

5 Fig. 1 viser et negativt engangs-formstykke 1. Formstykket er fremstillet af et formbart materiale, som omfatter polystyrenskum eller andre kunststoffer, der ligeledes kan opskummes og bearbejdes og har styrkemæssige egenskaber som polystyrenskum.FIG. 1 shows a negative disposable molding 1. The molding is made of a moldable material comprising polystyrene foam or other plastics which can also be foamed and machined and having strength properties such as polystyrene foam.

10 Formstykket 1 er udformet, så det dækker hele brøndbunden og omfatter tre afgrænsninger. Den første afgrænsning 2 er udformet som et negativt aftryk af en komplet brøndbund med bundløb 5 og banketter 6. Den anden afgrænsning 3 er udført som en cirkelrund, plan flade 3a, hvis periferi støder op til den tredje afgrænsning 4, som i det væsentlige står vinkelret på 15 den plane flade 3a og danner forbindelse mellem den første afgrænsning 2 og den anden afgrænsning 3 og har et forløb, der matcher diameteren på et kerneformstykke 9 (se fig. 2).The molding piece 1 is designed to cover the entire well bottom and comprises three boundaries. The first boundary 2 is designed as a negative image of a complete well bottom with bottom run 5 and banquets 6. The second boundary 3 is formed as a circular, flat surface 3a, the periphery of which is adjacent to the third boundary 4, which essentially stands perpendicular to the planar surface 3a and connecting the first boundary 2 to the second boundary 3 and having a path matching the diameter of a core molding 9 (see FIG. 2).

Formstykket 1 kan udføres med bundløbet 5 i forskellige varianter. Det kan 20 udføres med et retlinet forløb, som et forløb med en bøjning eller som et forløb med afgreninger, og med forskellige koter for ind- og udløbsåbningerne 13,14.The molding piece 1 can be made with the bottom run 5 in different variants. It can be carried out with a straight line, as a bend or as a branch with branches, and with different angles for the inlet and outlet openings 13, 14.

Banketterne 6, der udgør den del af brøndbunden, som ligger mellem 25 bundløbene 5 og brøndens inderside, udformes med fald hen imod bundløbene således, at partikler, slam og andet vandholdigt affald ikke kan samles og således, at rotter ikke kan finde redeplads.The banquets 6, which constitute the part of the well bottom which lies between the bottom 5s and the inside of the well, are designed to fall towards the bottom so that particles, sludge and other aqueous waste cannot be collected and so that rats cannot find nesting space.

Formstykket 1 er fremstillet af en enkel massiv blok af kunststof på en pro-30 grammerbar maskine efter indlæste specifikationer. Den programmerbare maskine er typisk en robot eller en CNC-maskine med fræseværktøjer 6 DK 176847 B1 påmonteret, men også andre typer værktøj er velegnet til bearbejdning af opskummet kunststof vil kunne anvendes på den programmerbare maskine.The die 1 is made of a simple solid block of plastic on a programmable machine according to loaded specifications. The programmable machine is typically a robot or a CNC machine with milling tools 6 DK 176847 B1 mounted, but other types of tools suitable for machining foamed plastic can be used on the programmable machine.

5 Oplysningerne om brøndbundens størrelse, bundløbenes forløb, banketter nes hældning, størrelsen af tilslutningernes åbning, deres antal, vinklen mellem åbningerne og deres koter danner grundlag for fremstilling af 3D tegninger på et CAD-anlæg, hvilke tegninger ligger til grund for dannelse af programspecifikationer i et CAM-anlæg til indlæsning i den programmer- 10 bare bearbejdningsmaskine.5 The information on the size of the well bottom, the course of the bottom courses, the inclination of the banquets, the size of the openings of the connections, their number, the angle between the openings and their quotas form the basis for the production of 3D drawings on a CAD system, which drawings form the basis of program specifications in a CAM system for loading into the programmable machining machine.

Fig. 2 viser et snitbillede af en form til støbning af en brøndbund af beton, inden engangs-formstykket 1 er monteret.FIG. 2 shows a sectional view of a mold for casting a concrete well bottom before the disposable molding piece 1 is mounted.

15 Formen omfatter en yderform 7, som består af to halvparter af stål, der kan spændes sammen og danne et cylindrisk kammer. Yderformen er udstyret med kraver i top og bund til afstivning af formen og til fastspænding på en bundramme 8.The mold comprises an outer mold 7, which consists of two half parts of steel that can be clamped together to form a cylindrical chamber. The outer mold is equipped with top and bottom collars for stiffening the mold and for clamping on a bottom frame 8.

20 Bundrammen 8 er korsformet og har en størrelse, så den kan optage yder-formen med krave til fastspænding. På bundrammen inde i yderformen placeres en formkerne 9 af stål. Den fastspændes til bundrammen 8.The bottom frame 8 is cruciform and has a size so that it can accommodate the outer mold with collar for clamping. On the bottom frame inside the outer mold is placed a mold core 9 of steel. It is clamped to the bottom frame 8.

Højden og diameteren af formkernen kan reguleres efter opgaven ved 25 justering på en spændeanordning. Godstykkelsen af brøndbundens sider bestemmes af forskellen mellem yderformens indvendige diameter og formkernens udvendige diameter. Godstykkelsen af bunden kan bl.a. reguleres ved at ændre højden af formkernen 9.The height and diameter of the mold core can be adjusted according to the task by adjusting on a clamping device. The thickness of the wellbond sides is determined by the difference between the outer diameter of the outer mold and the outer diameter of the mold core. The thickness of the base may include is adjusted by changing the height of the mold core 9.

30 Formkernens øverste afgrænsning dannes af en topplade 11, som spændes fast på formkernen.The upper boundary of the mold core is formed by a top plate 11 which is clamped onto the mold core.

DK 176847 B1 7DK 176847 B1 7

Uden om formkernen er der placeret en profilring 10. Den er fastspændt til bundrammen 8. Profilringen danner en fordybning i det færdige emne, og forløber hele vejen rundt i midten af brøndringens kant. I fordybningen kan 5 der anbringes et tætningselement. Fordybningen virker også som styr for en efterfølgende brøndring.Outside the mold core, a profile ring 10 is placed. It is clamped to the bottom frame 8. The profile ring forms a recess in the finished workpiece and extends all the way around the center of the edge of the well ring. In the recess a sealing element can be placed. The recess also acts as a guide for a subsequent well change.
