Betonvloeren, al of niet in systeem gemaakt, die door chloridenvervuiling en het daaruit ontstane "betonrot" d.m.v. een ondervloer op basis van hardschuim, hun oorspronkelijke constructiewaarden laten behouden of 5. weer hervinden.Concrete floors, whether or not made in system, which are contaminated by chloride pollution and the resulting "concrete rot" by means of Have a hard foam-based subfloor retain or restore their original construction values.
KENMERKCHARACTERISTIC
Het idee komt voort uit de algemeen begrijpelijke wens 10. dat e.e.a. kan worden uitgevoerd, zonder noemenswaardige overlast te bezorgen aan de gebruikers van een gebouw, door niet onnodig te slopen of te veranderen aan de bovenkant van de bedoelde vloeren.The idea stems from the generally understandable desire 10. that this can be carried out, without causing any significant inconvenience to the users of a building, by not unnecessarily demolishing or changing the top of the intended floors.
Voor wat overlast betreft, zal deze toepassing zich dan 15. ook richten naar de onderkant van de bedoelde vloeren c.q. het werk zal zich voornamelijk afspelen in de respectievelijke kruipruimtes.As far as nuisance is concerned, this application will also 15. focus on the underside of the intended floors, or the work will mainly take place in the respective crawl spaces.
Deze uitvinding of toepassing voorziet erin, door met behulp van een constructief metalen frame dat wordt 20. opgevuld met hardschuim, een ondervloer te creëren die voldoende ondersteuning biedt om het gewicht en de toelaatbare belasting van de oorspronkelijke systeemvloer te dragen.This invention or application provides, by using a structural metal frame that is filled with rigid foam, to create a subfloor that provides sufficient support to support the weight and permissible load of the original system floor.
Het verdient aanbeveling om voor elke maat van de 25. overspanning die een bestaande vloer heeft, een soort en maat van het metalen profiel te kiezen die overeenkomt met de belasting die er op wordt uitgeoefend.It is recommended that for each size of the 25. span that an existing floor has, choose a type and size of the metal profile that corresponds to the load that is applied to it.
Het hardschuim dat in situ moet kunnen worden verwerkt en vloeibaar moet kunnen worden geïnjecteerd, kan bij 30. een s.g. van maximaal 80kg./ M3. een druk weerstaan van minimaal 10 x de benodigde druk voor het opvangen van de bestaande systeemvloer.The hard foam which must be able to be processed in situ and which must be able to be injected in liquid form can be used at 30. a s.g. of maximum 80kg./ M3. withstand a pressure of at least 10 times the pressure required to absorb the existing system floor.
Dergelijke technieken bestaan reeds, maar worden dan T010743 -2- alleen gebruikt om te vullen, zonder eisen te stellen aan de draagkracht van het schuim.Such techniques already exist, but are then only used for filling T010743 -2-, without imposing requirements on the carrying capacity of the foam.
Deze toepassing is in feite een aanvulling op een reeds bestaand octrooi dat het schuim gebruikt als 5. constructief draagkrachtig en dat met deze eigenschappen d.m.v. injectie verzakte bouwdelen een "liftende werking" geeft. (Octrooinummer 1003362 en literatuurstudie naar lichte ophoogmaterialen W-DWW-93-507 Min.v.Verkeer en Waterstaat. Dienst Weg en 10. Waterbouw.)This application is in fact an addition to a pre-existing patent that uses the foam as a structural load-bearing and with these properties by means of injection sagging building parts gives a "lifting effect". (Patent number 1003362 and literature study into light embankment materials W-DWW-93-507 Min.v.Veereer en Waterstaat. Dienst Weg en 10. Waterbouw.)
Het metalen frame kan bij de montage zodanig worden gefabriceerd dat door het monteren van de verschillende onderdelen er één geheel kan worden gemaakt.The metal frame can be manufactured during assembly in such a way that by assembling the different parts one can be made into one whole.
De bekisting van het geheel die tussen het frame en de 15. betonvloer wordt gebruikt, kan variëren van een normale houten betonbekisting tot een hoogwaardige, rotbestendige, al of niet plaatstalen bekisting.The formwork of the whole used between the frame and the 15. concrete floor can vary from normal wooden concrete formwork to a high-quality, rot-resistant, whether or not sheet steel formwork.
20. De montage van dit systeem werkt als volgt;20. The mounting of this system works as follows;
Het systeem bestaat in principe uit een voldoende sterk metalen frame dat zodanig wordt opgebouwd dat de ruimte , tussen het frame en de bestaande betonvloer kan worden opgevuld met het eerder genoemde bekistingmateriaal. Er 25. wordt onder de vloer aan 2 kanten in de fundering, een metalen profiel bevestigd, welke we in dit stuk "de oplegging" noemen. De bevestiging gebeurt met chemische of mechanische ankers. Deze hoeklijn dient als drager voor het frame. Metalen balken met een bepaald vereist 30. profiel, worden op de oplegging geplaatst. Dit geheel noemen we "het frame". Door op of in dit frame van de gebruikte profielen een voldoende sterke plaat te plaatsen kan het frame als bekisting gaan fungeren voor 1010743 -3- een later in te spuiten, ambulant en vloeibaar hardschuim. De soort en maat van het profiel dat in het frame wordt verwerkt wordt per object bepaald aan de hand van de overspanning en de vloerbelasting. Door 5. afwisselend telkens profielen en een plaat bekistingmateriaal op de oplegging te plaatsen wordt nu de constructieve ondervloer gebouwd. Op 4 hoeken van het frame worden sparingen gehouden die dienen als vul en ontluchtingsopeningen. Tussen het frame en de bestaande 10. vloer is enige ruimte gehouden die per object verschillend kan zijn. In deze ruimte wordt een z.g.n. vulzak geplaatst. Deze zak heeft de maten van de betreffende vloer en is voopzien van injectie en ontluchtingssluizen. De zak heeft een bepaalde overmaat 15. t.o.v. de vloer om eventuele oneffenheden soepel te kunnen overbruggen. Nadat de vulzak is geplaatst wordt deze d.m.v. injectie gevuld met vloeibaar hardschuim totdat de zak "vol en zat" is en op spanning is gezet.In principle, the system consists of a sufficiently strong metal frame that is constructed in such a way that the space between the frame and the existing concrete floor can be filled with the aforementioned formwork material. A metal profile is attached under the floor on 2 sides in the foundation, which we refer to in this section as "the support". The fixing is done with chemical or mechanical anchors. This angle line serves as a support for the frame. Metal beams with a certain required 30. profile, are placed on the support. We call this whole "the frame". By placing a sufficiently strong plate on or in this frame of the profiles used, the frame can act as formwork for 1010743 -3- later injectable, ambulatory and liquid rigid foam. The type and size of the profile that is incorporated in the frame is determined per object on the basis of the span and the floor load. By placing profiles and a sheet of formwork material alternately on the support, the constructive subfloor is now being built. At 4 corners of the frame are recesses that serve as filling and venting openings. There is some space between the frame and the existing 10. floor that can differ per object. A so-called no. filling bag placed. This bag has the dimensions of the relevant floor and is provided with injection and vent valves. The bag has a certain oversize 15 to the floor to smoothly bridge any unevenness. After the filling bag has been placed, it is dm.v. injection filled with rigid liquid foam until the bag is "full and fed" and tensioned.
De zak zelf verliest zijn functie als het schuim is 20. uitgehard. De geileertijd van het hardschuim wordt afgesteld op de tijd die nodig is om de zak te vullen. Als laatste worden de injectie en ontluchtingssluizen afgesloten.The bag itself loses its function when the foam is cured. The hard foam foam time is adjusted to the time it takes to fill the bag. Finally, the injection and vent valves are closed.
25.25.
