Description
i 147574in 147574
Den foreliggende opfindelse angår en fremgangsmåde ved forskal-ling/støbning af betonvægge og af den i indledningen til krav 1 angivne art. For at betonen ikke skal binde til afstandsholderne, beskyttes disse i mange tilfælde af plastrør eller hylstre, der kan være cirkulære eller rektangulære.The present invention relates to a method of grinding / casting concrete walls and of the kind specified in the preamble of claim 1. In order not to bind the concrete to the spacers, in many cases these are protected by plastic pipes or casings which can be circular or rectangular.
Når betonblandingen er hærdet, fjernes forskallingerne, og afstandsholderne trækkes ud af de beskyttende plastrør, der imidlertid bliver siddende tilbage i betonen. De huller, som dannes af plastrørene, udfyldes med en passende cementmørtel fra begge sider, en proces, der er forholdsvis tidskrævende, og hyppigt er det vanskeligt at få fyldt hullet fuldstændigt, hvilket blandt andet kan føre til lydgennemgang. Ved visse former for stålforskallinger benyttes stålkonusser i stedet for plastrør til beskyttelse af afstandsholderen. Når canentblan-dingen er hærdet, fjernes afstandsholderen, og derefter slås konusserne ud, og hullerne fyldes med betonmørtel eller betonkonusser. De ovenfor nævnte fremgangsmåder er enten for dyre eller ikke tilfredsstillende. Derudover vil stålkonus- -ser, når de bruges til en krydsfinerform, deformere denne.When the concrete mix is hardened, the formwork is removed and the spacers are pulled out of the protective plastic tubes, which however remain in the concrete. The holes formed by the plastic pipes are filled with a suitable cement mortar from both sides, a process that is relatively time-consuming and frequently it is difficult to fill the hole completely, which can, among other things, lead to sound penetration. In certain types of steel formwork, steel cones are used instead of plastic tubes to protect the spacer. When the cane mixture is hardened, the spacer is removed and then the cones are knocked out and the holes filled with concrete mortar or concrete cones. The above-mentioned methods are either too expensive or unsatisfactory. In addition, when used for a plywood mold, steel cones will deform it.
Det er den foreliggende opfindelses formål at undgå de ovenfor nævnte ulemper ved at anvise en ny fremgangsmåde, der er væsentlig billigere og betydeligt mere arbejdsbesparende end de kendte fremgangsmåder, og som resulterer i færdige vægge, der tilfredsstiller kravene med hensyn til decibeltransmission.SUMMARY OF THE INVENTION It is an object of the present invention to avoid the aforementioned disadvantages of providing a new method which is substantially cheaper and considerably more labor-saving than the known methods and which results in finished walls that satisfy the requirements of decibel transmission.
Dette formål tilgodeses ved, at den indledningsvist omtalte fremgangsmåde ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 anførte, hvorved man opnår, at de tilbageværende huller meget enkelt og let kan tætnes ved, at man kun indfører letbetonkonussen, der er forsynet med klæbemiddel, ind i de tilbageværende huller. Opfindelsen angår også en fremgangsmåde til fremstilling af en letbetonkonus til brug ved den ovenfor omtalte fremgangsmåde, som anført i indledningen til krav 2. Ved det i den kendetegnende 2 147574 del af krav 2 anførte opnår man på enkel måde, at letbetonkonus-. , sernes længde kan justeres ved af savning på tværs af deres længderetning, medens konusserne stadig befinder sig i deres støbeform, idet der i hver enkel støbeform befinder sig et antal koniske elementer, således at elementerne i' hver støbeform kan justeres i længderetningen i en enkelt arbejdsgang ved at save gennem støbeformen med de der værende koniske elementer.This object is met by the fact that the method according to the invention mentioned above is characterized by the method of claim 1, whereby the remaining holes can be very easily and easily closed by introducing only the lightweight concrete cone which is provided. with adhesive, into the remaining holes. The invention also relates to a method for producing a lightweight concrete cone for use in the above-mentioned method, as set out in the preamble of claim 2. By the characterizing part of claim 2, it is readily achieved that lightweight concrete cones. , the length of the molds can be adjusted by sawing across their longitudinal direction while the cones are still in their mold, with in each mold a plurality of conical elements so that the elements of each mold can be adjusted longitudinally in a single direction. workflow by cutting through the mold with the tapered elements.
Ved hjælp af den foreliggende fremgangsmåde 'kan efterbehandlingen af støbt betonvæg således foretages hurtigt og rationelt i forhold til de hidtil mest almindeligt benyttede teknik, hvor man fylder hvert enkelt hul med mørtel og puds'.Thus, by the present method 'the finishing of cast concrete wall can be done quickly and rationally in relation to the hitherto most commonly used technique, where each hole is filled with mortar and plaster'.
Nedenfor gives en noget mere detaljeret redegørelse for fremgangsmåden ifølge opfindelsen.A somewhat more detailed description of the method according to the invention is given below.
I stedet for plastrør og stålkonusser benyttes på kendt måde koniske plastelementer i forbindelse med forskallingen, hvilke elementer kan benyttes mange gange og er væsentlig lettere end tilsvarende stålkonusser. Koniske plastelementer kan anvendes til alle typer forskallinger i modsætning til stålkonusser., der ved brug til en krydsfinerform deformerer denne. Ved anvendelse .af egnet plastmateriale for det koniske plastelement er det muligt at få en konus, der nemt udtrækkes fra den hærdede beton, er tilstrækkeligt blød til ikke at deformere formvæggen, og som samtidigt har tilstrækkelig·styrke til at modstå de belastninger, som den underkastes under støbningen.Instead of plastic pipes and steel cones, conical plastic elements are used in connection with the formwork, which elements can be used many times and are considerably lighter than corresponding steel cones. Tapered plastic elements can be used for all types of formwork as opposed to steel cones which, when used in a plywood form, deform it. By using suitable plastic material for the conical plastic element, it is possible to obtain a cone that is easily extracted from the hardened concrete, is sufficiently soft not to deform the mold wall, and at the same time has sufficient strength to withstand the stresses it be subjected during casting.
Som letbetonkonus bvenyttes ved fremgangsmåden ifølge opfindelsen fortrinsvis en konus af hærdet skumbeton. Skumbeton er en tyndtflydende opskummende cementblanding, som kræver vandtætte forme.As a lightweight concrete cone, a method of hardened foam concrete is preferably used in the process according to the invention. Foam concrete is a thin-flowing foaming cement mix that requires watertight molds.
Til fremstilling af disse betonkonusser benyttes en ikke-kra- i kelerende skumbetonblanding, der støbes i vandtætte isolerende forme.For the preparation of these concrete cones, a non-cracking foam concrete mix is used, which is cast in waterproof insulating molds.

Som vandtæt varmeisolerende støbeform for konusserne benyttes på kendt måde en skumplastform. Som følge af skumpla stens gode isoleringsegenskaber er det let at kontrollere temperaturen under hærdningstiden, hvilket fører til en ensartet kvalitet for de hærdede og færdige konusser. En foretruk-ken udførelsesform kan indbefatte en skumplastblok, hvori der er udboret eller på anden måde er fremstillet et antal huller med den ønskede diameter for formen, således at det er muligt at støbe mange konusser i én og samme blok. Da en sådan skumplastblok er forholdsvis billig, vil den også kunne tjene som transportemballage for de hærdede konusemner. Ifølge opfindelsen opnås en yderligere fordel ved at støbe konusserne af letbeton i den ovenfor beskrevne form ved, at de færdige konussers længde nemt kan afpasses ved, at hele kombinationen af hærdede eller tilnærmelsesvis hærdede konusemner og formen skæres eller saves til korrekt længde. Ved at konusemnerne ligger delvis fastholdt i deres form, vil man i et enkelt arbejdstrin kunne afskære eller ge'nnemsave et stor antal konusser til den ønskede længde. På denne måde er det muligt at fremstille konusser med længder,der er nøjagtigt tilpasset den aktuelle vsgtykkelse.As a waterproof heat-insulating mold for the cones, a foam plastic is used in a known manner. Due to the good insulating properties of the foam, it is easy to control the temperature during the curing time, which leads to a uniform quality for the cured and finished cones. A preferred embodiment may include a foam plastic block in which a bore or otherwise made of a number of holes of the desired diameter for the mold is made so that it is possible to mold many cones into one and the same block. Since such a foam plastic block is relatively inexpensive, it can also serve as transport packaging for the cured cone blanks. According to the invention, a further advantage of casting the lightweight concrete cones in the above-described form is obtained by the fact that the length of the finished cones can be easily adjusted by cutting or cutting the entire combination of hardened or approximately hardened cone pieces to the correct length. By partially holding the cone blanks in their shape, you can cut or cut a large number of cones to the desired length in a single working step. In this way, it is possible to produce cones with lengths exactly adapted to the current thickness.
De med langsgående huller forsynede konisk formede plastelementer anbringes i forskallingen før støbning, og afstandsholderne føres gennem de koniske elementer og fastgøres til formen på kendt måde. Efter at støbningen er hærdet, fjernes forskallingen og afstandsholderne, og de koniske plastelementer slås ud ved hjælp af et egnet redskab. Derefter påføres de forud fremstillede letbetonkonusser et egnet klæbemiddel og indsættes i de huller, hvorfra plastkonusserne er blevet fjernet. Da letbeton er relativt blød, kan man både sømme og save i den, eller den kan om ønsket behandles på anden måde.The conical shaped plastic elements with longitudinal holes are placed in the formwork before casting, and the spacers are passed through the conical elements and secured to the mold in a known manner. After the casting has hardened, the formwork and spacers are removed and the tapered plastic elements are knocked out using a suitable tool. Then the pre-made lightweight concrete cones are applied to a suitable adhesive and inserted into the holes from which the plastic cones have been removed. Since lightweight concrete is relatively soft, both seams and saws can be used, or it can be treated differently if desired.
