Abstract

Injection system for the sealing of joints in concrete structures having joint surfaces arising from stepwise casting of such structures and extending between an outer or upper side (the water pressure side) and an inner or lower side (the dry side), for the purpose of preventing penetration of moisture from the water pressure side. The system comprises a per se known profile (1) having a lengthwise through injection passage (3) with an opening (4, 5) to that side of the profile which is to face the joint surface (6), in combination with a per se known swelling material (8, 9) attached to the profile on that side thereof which is to face the water pressure side of the concrete structure. The swelling material (8, 9) shall be disposed along the full length of the profile (1) and around at least one of the end faces of the profile. The opening (4, 5) from the injection passage (3) may be in the form of a continuous slot (4) opening into a widened portion (5) adapted to receive a porous barrier against the intrusion of concrete mass to the injection passage.

Description

Foreliggende oppfinnelse angår et injeksjonssystem for fugetetting i betong- o.l. konstruksjoner. Spesielt, men ikke utelukkende, får oppfinnelsen sin anvendelse for fugetetting ved overgangen (fugen) mellom en grunnmursåle og grunnmur-ytter-veggene. The present invention relates to an injection system for joint sealing in concrete and the like. constructions. In particular, but not exclusively, the invention is used for joint sealing at the transition (joint) between a foundation wall sole and the foundation wall outer walls.

Det er alminnelig kjent at det kan oppstå riss, sprekker o.l. i betongkonstruksjoner, særlig i forbindelse med fuger mellom betongstøp som foretas til forskjellig tid. Disse riss, sprekker o.l. oppstår eksempelvis som følge av manglende homogenitet eller annen konsistensmangel i betongen eller som følge av betongens herdekrymping, og den kan føre til vanngjennomtrengning. It is common knowledge that cracks, fissures etc. can occur. in concrete structures, especially in connection with joints between concrete casts which are made at different times. These cracks, cracks etc. occurs, for example, as a result of a lack of homogeneity or other lack of consistency in the concrete or as a result of the concrete's curing shrinkage, and it can lead to water penetration.

For å utbedre slike sprekk- og riss-skader i betongen og for å oppnå tetting av betongen mot vanngjennomtrengning har det tidligere vært foreslått en punktvis injeksjon av et tettende material, særlig i form av et polymer. Andre injeksjonsmaterial-er som benyttes for dette formål er polyuretaner, epoksyer, akryl-geler og mikro-sementer. Det foreligger dessuten flere forslag til injeksjonsslanger som støpes inn i betongen for å tillate etterfølgende injeksjon av tettematerial, eller som anbringes langs en fugeflate på et allerede støpt parti, f.eks. en fundament såle, før det påfølgende parti, f .eks. en fundament-yttervegg, støpes. Slike injeksjonsslanger er omtalt eksempelvis i US patent 4.499.925, EPO publ. 0.125.696, norsk patent 163194 og norsk patentsøknad 911086. In order to repair such crack and tear damage in the concrete and to achieve sealing of the concrete against water penetration, it has previously been proposed to inject a sealing material at points, particularly in the form of a polymer. Other injection materials used for this purpose are polyurethanes, epoxies, acrylic gels and micro-cements. There are also several proposals for injection hoses which are cast into the concrete to allow subsequent injection of sealing material, or which are placed along a joint surface on an already cast part, e.g. a foundation sole, before the following lot, e.g. a foundation-external wall, is cast. Such injection hoses are described, for example, in US patent 4,499,925, EPO publ. 0.125.696, Norwegian patent 163194 and Norwegian patent application 911086.

Foreliggende oppfinnelse går ut på et injeksjonssystem for fugetetting i betongkonstruksjoner, med en fugeflate som oppstår ved trinnvis støping og som strekker seg mellom en ytre eller øvre side (vanntrykkside) og en indre eller lavere side, for å hindre gjennomtrengning av fuktighet fra vanntrykksiden, hvorved utleggingen blir vesentlig enklere og sikrere og virkningen blir sterkt forbedret. Det særegne ved injeksjonssystemet i henhold til oppfinnelsen består i at det omfatter The present invention concerns an injection system for joint sealing in concrete constructions, with a joint surface which is created by stepwise casting and which extends between an outer or upper side (water pressure side) and an inner or lower side, to prevent the penetration of moisture from the water pressure side, whereby the installation becomes significantly easier and safer and the effect is greatly improved. The distinctive feature of the injection system according to the invention is that it includes

a) et i og for seg kjent profil med langsgående gjennomgående injeksjonskanal med åpning ut mot den side av profilet som a) a profile known in and of itself with a longitudinal continuous injection channel with an opening towards the side of the profile which

skal ligge mot fugeflaten , i kombinasjon med must lie against the joint surface, in combination with

b) et i og for seg kjent svellende material festet til profilet på den side av dette som skal vende mot vanntrykksiden av betongkonstruksjonen, og at c) det svellende material er anordnet langs hele lengden av profilet og rundt den ene endeflate av dette. b) a known in itself swelling material attached to the profile on the side of it which is to face the water pressure side of the concrete structure, and that c) the swelling material is arranged along the entire length of the profile and around one end surface thereof.

Ytterligere trekk ved oppfinnelsen vil fremgå av de etterfølg-ende patentkrav. Further features of the invention will appear from the subsequent patent claims.

Oppfinnelsen skal nærmere beskrives under henvisning til vedføyde tegning. Fig. 1, 2 og 3 viser et tverrsnitt gjennom tre alternative uftørelsesformer for et profil for anvendelse i et injeksjonssystem i henhold til foreliggende oppfinnelse. Fig. 4 viser skjematisk en leggemåte for profilenheter i et injeksjonssystem i overensstemmelse med oppfinnelsen. The invention shall be described in more detail with reference to the attached drawing. Figs. 1, 2 and 3 show a cross-section through three alternative unwitting forms for a profile for use in an injection system according to the present invention. Fig. 4 schematically shows a method of laying profile units in an injection system in accordance with the invention.

I henhold til oppfinnelsen omfatter et injeksjonssystem for fugetetting i betongkonstruksjoner et langstrakt profil 1 med en langsgående kanal 3 med åpning 4, 5 ut mot undersiden av profilet, som skal vende mot en fugeflate 6 i betongkonstruksjonen. Langs denne undersiden er profilet 1 utformet med en leppe eller flens 7 langs den ene sidekant, innrettet til å ligge mot fugeflaten 6 og mot den innovervendende side av betongkonstruksjonen. På den siden av profilet 1 som skal vende utover i forhold til betongkonstruksjonen, dvs. til dennes "vanntrykkside", er det festet et svellende material i form av "pølser" 8 (fig. 1) eller strimler 9 (fig. 2, 3). Hensiktsmessig er profilet 1 utformet med en langsgående leppe eller flens 10 som dekker i det minste noe av oversiden av det svellende material 8, 9. Det svellende material 8, 9 er festet til profilet 1 ved hjelp av klebemiddel og/eller ved hjelp av mothaker 11 (fig. 2) eller ved å holdes bak flenser e.l. 12 (fig. 1) . Som det fremgår av fig. 4 er det svellende material 8, 9 brettet rundt den ene ende av profilet. Det svellende material 8, 9 vil, når det kommer fuktighet til, svelle til å bli bortimot 100% fuktighets-ugjennomtrengelig. According to the invention, an injection system for joint sealing in concrete structures comprises an elongated profile 1 with a longitudinal channel 3 with opening 4, 5 towards the underside of the profile, which must face a joint surface 6 in the concrete structure. Along this underside, the profile 1 is designed with a lip or flange 7 along one side edge, arranged to lie against the joint surface 6 and against the inward-facing side of the concrete structure. On the side of the profile 1 which should face outwards in relation to the concrete structure, i.e. to its "water pressure side", a swelling material in the form of "sausages" 8 (fig. 1) or strips 9 (fig. 2, 3 ). Conveniently, the profile 1 is designed with a longitudinal lip or flange 10 which covers at least some of the upper side of the swelling material 8, 9. The swelling material 8, 9 is attached to the profile 1 by means of adhesive and/or by means of barbs 11 (fig. 2) or by being held behind flanges etc. 12 (fig. 1) . As can be seen from fig. 4, the swelling material 8, 9 is folded around one end of the profile. The swelling material 8, 9 will, when moisture enters, swell to become almost 100% impermeable to moisture.

Ved hjelp av tilløps- og fraløps-slanger 13 (fig. 4) tilføres kanalen 3 et tettende material, f .eks. i form av en polymer, som trenger gjennom slissen 4 og det utvidete parti 5 og ut til sprekker og riss i betongen. For å hindre at betongmaterial ved den etterfølgende støping skal trenge inn i det utvidete parti 5 og videre inn i slissen 4 og derved hindre injeksjonsmaterial-et fra å trenge ut til sprekkene og rissene, er det hensiktsmessig anordnet en "pølse" (ikke vist) av et gjennomgående porøst material i det utvidete parti 5. Denne pølsen vil, sammen med leppen eller flensen 7, bevirke at hele anordningen i overensstemmelse med oppfinnelsen får et gjennomgående fullstendig anlegg mot fugeflaten, uhindret av eventuelle ujevnheter i denne. Det ligger innenfor oppfinnelsens ramme å utforme profilet 1 med den slissformede åpning 4 direkte fra kanalen 3 og ut mot undersiden av profilet, uten å gi plass for noen porøs pølse som hindrer inntrengning av støpemasse til slissen 4 og kanalen 3. By means of inlet and outlet hoses 13 (fig. 4), a sealing material is supplied to the channel 3, e.g. in the form of a polymer, which penetrates through the slit 4 and the extended part 5 and out to cracks and cracks in the concrete. In order to prevent concrete material during the subsequent casting from penetrating into the extended part 5 and further into the slot 4 and thereby preventing the injection material from penetrating to the cracks and cracks, a "sausage" is appropriately arranged (not shown) of a continuous porous material in the extended part 5. This sausage will, together with the lip or flange 7, cause the entire device in accordance with the invention to have a continuous complete contact with the joint surface, unimpeded by any unevenness therein. It is within the framework of the invention to design the profile 1 with the slot-shaped opening 4 directly from the channel 3 and out towards the underside of the profile, without leaving room for any porous sausage that prevents the penetration of molding compound into the slot 4 and the channel 3.

Profilet 1 med påfestet svellende material 8, 9 og monterte tilløps- og fraløpsslanger 13 leveres og monteres hensiktsmessig som enheter, eksempelvis med lengder på 3 eller 6 meter, og monteres på en slik måte at det svellende material 8, 9 danner en sammenhengende barriere. Dette oppnås ved at de enkelte enheter legges noe forsatt ved de innbyrdes tilstøtende ender, f .eks. slik som antydet i fig. 4, hvorved det svellende material 8, 9 på den ene enhet ligger tett mot det svellende material på en tilstøtende enhet. Fig. 4 viser bare ett av mange mulige leggemønstre som antas å ikke trenge nærmere beskrivelse her. The profile 1 with attached swelling material 8, 9 and fitted inlet and outlet hoses 13 is supplied and fitted appropriately as units, for example with lengths of 3 or 6 metres, and is fitted in such a way that the swelling material 8, 9 forms a continuous barrier. This is achieved by placing the individual units slightly offset at their mutually adjacent ends, e.g. as indicated in fig. 4, whereby the swelling material 8, 9 on one unit lies close to the swelling material on an adjacent unit. Fig. 4 shows just one of many possible laying patterns which are assumed not to need further description here.
