Opfindelsen angår en væsketæt betonelementsamling til dannelse af et kammer med en bund og sider bestående af i hovedsagen rektangulære betonelementer og mellem disse anbragt tætningsmateriale.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a liquid-tight concrete element assembly for forming a chamber having a bottom and sides consisting of substantially rectangular concrete elements and between sealing material disposed therebetween.
5 Sådanne betonelementsamli nger anvendes f.eks. som fjernvarmebrønde, udskil lebrønde o.l., hvor der ved nedgravning af sådanne er behov for tætning mod indtrængende eller udstrømmende væske, eksempelvis vand.Such concrete element joints are used e.g. such as district heating wells, separate wells and the like where, when buried, such sealing is required for penetrating or outflowing liquid, for example water.
10 Ved kendte samlinger er sideelementerne monteret således, at to elementer er indspændt mellem to øvrige sideelementer, og bundelementet er indspændt mellem sideelementerne. Tætningsmaterialet er således anbragt mellem et sideelements endeflade og et tilstødende elements sideflade samt mellem side- og bundelementet. Dette bety-15 der, at det tætningsmateriale, der forløber horisontalt, vil overlappe vertikalt forløbende tætningsmateriale, således at der vil være mange frie ender ved samlepunkterne.In known assemblies, the side elements are mounted such that two elements are clamped between two other side elements and the bottom element is clamped between the side elements. The sealing material is thus disposed between the end surface of a side element and the side surface of an adjacent element as well as between the side and bottom element. This means that the sealing material extending horizontally will overlap vertically extending sealing material so that there will be many free ends at the focal points.
Herved opstår der mulighed for utætheder ved overlapningsstedet 20 eller samlestedet.This creates the possibility of leaks at the overlap 20 or the assembly point.
Derudover kræver en sådan betonelementsamling, at de anvendte betonelementer fremstilles inden for meget små tolerancer for at sikre en tilnærmelsesvis væsketæt samling. Dette betyder, at der 25 stilles store krav til produktionsprocessen samt til samleprocessen., som bliver meget tidskrævende.In addition, such a concrete element assembly requires that the concrete elements used be manufactured within very small tolerances to ensure an approximate fluid tight assembly. This means that there are high demands on the production process as well as on the assembly process, which will be very time-consuming.
Formålet med opfindelsen er derfor at angive en betonelementsamling, der kan monteret enkelt og hurtigt samtidig med, at en effektiv 30 tætning mod væskeindtrængning eller -udstrømning sikres.The object of the invention is therefore to provide a concrete element assembly which can be mounted simply and quickly while ensuring an effective seal against liquid penetration or outflow.
Dette opnås ved en betonelementsamling, der er karakteristisk ved, at tætningsmaterialet har form som en liste og forløber horisontalt langs hvert sideelements nedre kant med en fri ende ved den ene 35 sidekant og vertikalt langs hvert sideelements anden sidekant, i ét stykke og fastgjort til elementet, at betonelementerne, der danner kammerets sider, ligger an mod bunddelens lodrette sider, således at hver tætningslistes horisontalt forløbende del tætner mod denne, og således at hvert betonelement med den endeflade, hvor tætningslis- DK 170427 B1 2 tens horisontale del har en fri ende, støder op mod den med tætningsliste forsynede side på et i hovedsagen vinkelret derpå beliggende betonelement, således at tætningslistens frie ende på et element støder op mod tætningslisten på et andet element omkring 5 området, hvor listen danner en i hovedsagen ret vinkel.This is achieved by a concrete element joint, characterized in that the sealing material is shaped like a strip and extends horizontally along the lower edge of each side element with a free end at one side edge and vertically along the other side edge of each side element, in one piece and attached to the element. that the concrete elements forming the sides of the chamber abut the vertical sides of the bottom part so that the horizontally extending portion of each sealing strip seals against it, and so that each concrete element with the end surface, where the horizontal part of the sealing strip has a free end , abuts the sealing strip side on a substantially perpendicular concrete element located thereon, so that the free end of the sealing strip abuts the sealing strip on another element about the region where the strip forms a generally right angle.
Herved er der angivet en betonelementsamling, der kan samles hurtigt og effektivt, idet der ikke som ved kendte samlinger stilles store krav til elementernes fremstillingstolerancer, og idet tætnings!is-10 terne kun har få indbyrdes berøringssteder. Især i byområder, hvor kloakledninger og fjernvarmerør føres sammen med vejnettet, er det vigtigt med en hurtig og effektiv montering, da trafikken generes meget ved udgravningsarbejdet.Hereby, a concrete element assembly is provided which can be assembled quickly and efficiently, as, as in prior art assemblies, no high demands are made on the manufacturing tolerances of the elements, and the sealing elements have only a few contact points. Especially in urban areas, where sewer lines and district heating pipes are routed together with the road network, it is important to have a fast and efficient installation, as traffic is greatly disturbed by the excavation work.
15 Tætningslisten er hensigtsmæssigt fremstillet af et fleksibelt kunststof, f.eks. syntetisk gummi, ved en ekstruderingsproces.The sealing strip is suitably made of a flexible plastic, e.g. synthetic rubber, by an extrusion process.
Særlig hensigtsmæssigt er tætningslisten udformet som et fleksibelt legeme med anordninger på ydersiden til indgreb i en rille på betonelementet. Anordningerne på listen kan være udformet som finner 20 eller modhager, hvilket sikrer en let indføring i rillen samtidig med, at en modstand mod udtrækning skabes.Particularly conveniently, the sealing strip is designed as a flexible body with devices on the outside for engagement in a groove on the concrete element. The devices on the list may be designed as fins 20 or barbs, which ensure easy insertion into the groove while creating a resistance to pull-out.
Fastholdelsen af sideelementerne mod hinanden og mod bundelementet sker eksempelvis ved sammenspænding. Således kan sideelementerne ved 25 deres ender samt bundelementet på dets lodrette sider være forsynede med indstøbte gevinddele, mens det op til endedelene stødende . naboelement er udformet med huller til bolte ud for de førnævnte gevinddele. Boltehullerne kan være dannet med en noget større diameter end boltenes skaftdiameter for således at tillade større 30 tolerancer ved fremstilling af betonelementerne og ved samlingen af disse. Mellem betonelementerne kan afstandsstykker anbringes ved sammenspændingen, således at tætningslisten ikke beskadiges ved for tæt sammenspænding af elementerne.The side elements are held against each other and against the bottom element, for example, by compression. Thus, the side members at their ends, as well as the bottom member on its vertical sides, may be provided with molded thread members while abutting the end members. adjacent elements are formed with holes for bolts next to the aforementioned threaded parts. The bolt holes may be formed with a somewhat larger diameter than the shaft diameter of the bolts so as to allow greater tolerances in the manufacture of the concrete elements and in their assembly. Between the concrete elements, spacers can be placed at the tension so that the sealing strip is not damaged by too tight tension of the elements.
35 Efter samling kan ringrummet mellem bolten og hullets væg eventuelt 1 udfyldes med et isolerende materiale for at imødegå korrosionsproblemer, der ellers kan forekomme.35 After assembly, the annulus between the bolt and the wall of the hole may optionally be filled 1 with an insulating material to counter corrosion problems that may otherwise occur.
Bundelementet kan fordelagtigt være udformet med udragende dele på DK 170427 B1 3 sine lodrette sideflader, mens sideelementerne kan have korresponderende udsparinger ved deres nedadvendende kanter. Ved montering af sidevæggene kan de udragende dele danne styr for sidevæggene og derved yderligere lette monteringen.The bottom member may advantageously be formed with protruding parts on its vertical side surfaces, while the side members may have corresponding recesses at their downward-facing edges. When mounting the sidewalls, the projecting parts can guide the sidewalls and thereby further facilitate mounting.

En udførelsesform for opfindelsen forklares i det følgende nærmere med henvisning til den ikke-begrænsende tegning, hvorAn embodiment of the invention is explained in more detail below with reference to the non-limiting drawing, in which
Fig. 1 viser en delvist færdiggjort betonelementsamling, 10 fig. 2 viser et hjørne af en betonelementsamling mere detaljeret og fig. 3A, B viser et tværsnit af en tætningsliste i en umonteret 15 tilstand henholdsvis monteret tilstand.FIG. 1 shows a partially completed concrete element assembly; FIG. 2 shows a corner of a concrete element assembly in more detail; and FIG. Figures 3A, B show a cross-section of a sealing strip in an unmounted state and mounted state respectively.
På fig. 1 vises en betonelementsamling bestående af fire sideelementer 1-4 samt en bunddel 5. Hver af sidevæggene 1-4 har på den mod kammerets indre vendende sideflade en tætningsliste 6-9, der er 20 monteret forløbende horisontalt langs elementets nedre kant, i en afstand fra denne, der ligger inden for tykkelsen af bunddelen 5 og vertikalt langs elementets ene sidekant, i en afstand fra denne, der ligger inden for tykkelsen af det tilstødende betonelement.In FIG. 1, a concrete element assembly consisting of four side elements 1-4 and a bottom part 5 is shown. Each of the side walls 1-4 has a sealing strip 6-9, which is mounted horizontally along the lower edge of the element, on the side face of the chamber interior facing the chamber. from it, which lies within the thickness of the bottom part 5 and vertically along one side edge of the element, at a distance from it which lies within the thickness of the adjacent concrete element.
25 På fig. 2 vises mere detaljeret et hjørne af betonelementsamli ngen vist på fig. 1.25 In FIG. 2, a corner of the concrete element assembly shown in FIG. First
Fig. 3A viser en tætningsliste 6-9 i en foretrukken udførelsesform. Listen er udformet med en tilnærmelsesvis cirkelrund del 10, hvorfra 30 en fastgørelsesdel 11 omfattende tilspidsede og mod begge sider udragende bøjelige finner 12. På fig. 3B er en sådan liste vist monteret i en rende 13 i et betonelement 1-4. Ved indføringen af listen i renden bøjes finnerne 12 mod renden 13's indføringsåbning, og disse vil således skabe en modstand mod udtrækning af listen 6-9 35 fra elementet 1-4.FIG. 3A shows a sealing strip 6-9 in a preferred embodiment. The molding is formed with an approximately circular part 10, from which 30 a fastening part 11 comprising tapered and projecting flexible fins on both sides 12. In FIG. 3B, such a list is shown mounted in a gutter 13 in a concrete element 1-4. Upon insertion of the groove into the gutter, the fins 12 bend toward the insertion opening of the groove 13, thus creating a resistance to extracting the groove 6-9 35 from the element 1-4.
Ved samling af elementerne føres et første element 1 op mod bunddelen 5, således at den horisontalt forløbende del af tætningslisten ligger an mod bunddelen, og at den endeflade af elementet, hvor den DK 170427 Bl 4 horisontalt forløbende tætnings!iste har en fri ende, forløber flugtende med en hosliggende sideflade af bunddelen.When assembling the elements, a first element 1 is brought up against the bottom part 5, so that the horizontally extending part of the sealing strip abuts the bottom part and that the end surface of the element, where the horizontally extending sealing strip has a free end, extends flush with an adjacent side surface of the bottom portion.
Den endeflade af et element, der er beliggende modsat endefladen med 5 tætningslistens frie horisontale ende, vil da være beliggende i en afstand fra bunddelen, der i alt væsentligt svarer til tykkelsen af et tilstødende betonelement. Et andet betonelement anbringes dernæst ved den endeflade, der omfatter den frie ende af den horisontale tætningsliste, således at den vertikalt forløbende del af tætnings-10 listen på det andet element ligger an mod det første betonelements endeflade på en sådan måde, at den frie ende af den horisontalt forløbende del af tætningslisten på det første element støder op mod tætningslisten på det andet element.The end surface of an element located opposite the end surface with the free horizontal end of the sealing strip will then be located at a distance from the bottom portion substantially corresponding to the thickness of an adjacent concrete element. A second concrete element is then placed at the end surface comprising the free end of the horizontal sealing strip, so that the vertically extending portion of the sealing strip on the second element abuts against the end surface of the first concrete element in such a way that the free end of the horizontally extending portion of the sealing strip of the first element adjacent to the sealing strip of the second element.
15 Et tredie element monteres analogt hermed i forbindelse med det andet og et fjerde i forbindelse med det tredie og samtidig i forbindelse med det første element.A third element is mounted analogously thereto in connection with the second and a fourth in connection with the third and at the same time in connection with the first element.
Hvert element forbindes til bunddelen 5 og til tilstødende sideele-20 menter ved sammenspænding med bolte. Derfor er alle sideelementerne forsynede med indstøbte gevinddele og huller til boltegennemføring (ikke vist). Bundelementet er udelukkende forsynet med indstøbte gevinddele (ikke vist). Hullerne i elementerne kan udformets med forholdsvis store diametre for derved at sikre en problemløs og ikke 25 toleranceafhængig sammenspænding. Mellem betonelementerne kan afstandsstykker indsættes for at sikre, at tætningslisten ikke -beskadiges. Efter sammenspænding kan ringrummet, der er dannet omkring boltene, fyldes med et flydende og størknende middel, eksempelvis et to-komponent klæbemiddel, for at sikre boltene mod 30 korrosion.Each element is connected to the bottom part 5 and to adjacent side elements by clamping with bolts. Therefore, all the side elements are provided with molded threaded parts and holes for bolt penetration (not shown). The base element is provided with embedded threaded parts only (not shown). The holes in the elements can be formed with relatively large diameters, thereby ensuring a trouble-free and not tolerance-dependent tension. Spacers can be inserted between the concrete elements to ensure that the sealing strip is not damaged. After tightening, the annulus formed around the bolts can be filled with a liquid and solidifying agent, for example a two-component adhesive, to secure the bolts against corrosion.
Betonelementsamlingen kan til afdækning forsynes med et dæksel af iøvrigt kendt type.The concrete element assembly can be provided with a cover of a otherwise known type for covering.
35 Ved anvendelse af den samlede betonelementkonstruktion ifølge opfindelsen som fjernvarmebrønd eller som udskil!erbrønd udformes sideelementerne med huller til rørgennemføring eller rørtilslutning.35 Using the assembled concrete element structure of the invention as district heating well or as separator well, the side elements are formed with holes for pipe entry or pipe connection.
