Description
<Desc/Clms Page number 1>
De uitvinding heeft betrekking op het fabriceren in prefab van balk- jes, die in doorsnede bijv. rechthoekig, rond of ovaal kunnen zijn, welke balk- jes dezelfde functie verrichten als het thans nog gebezigde voorgespannen beton.
In deze balkjes worden het voor een bepaald doel vereiste aantal staafjes of snaren van bijv. staal, nylon of soortgelijke materialen aangebracht. De staaf- jes of snaren worden omsloten door een snelwerkend cement, al dan niet voorzien van een toeslag, o. a. bestaande uit hollith, asbestvezel of anderstins.
De op deze wijze geprefabriceerde voorspanningsbalkjes kunnen in verschillende lengten gefabriceerd en geleverd worden.
Eén der voordelen van deze werkwijze is o.a., dat op elk willekeurig werk deze balkjes in de bekisting kunnen worden gelegde welke daarna omsloten wordt door de beton, zodat de sparingen waarin normaal de staven voorgespannen worden, niet meer door vloeibaar cement geïnjecteerd behoeven te worden.
Een ander voordeel is, dat bij toepassing van asbestoement als om- sluiting van de staafjes en snaren, de balk bestand is tegen zeer hoge tempera- turen. **WAARSCHUWING** Einde van DESC veld kan begin van CLMS veld bevatten **.

The invention relates to the prefabrication of beams, which in cross-section may for instance be rectangular, round or oval, which beams perform the same function as the prestressed concrete still used today.
In these bars the number of bars or strings of e.g. steel, nylon or similar materials required for a particular purpose are arranged. The rods or strings are enclosed by a fast-acting cement, which may or may not be provided with a supplement, eg consisting of hollith, asbestos fiber or other inserts.
The prestressing beams prefabricated in this way can be manufactured and supplied in various lengths.
One of the advantages of this method is, among other things, that on any given work these beams can be placed in the formwork, which is then enclosed by the concrete, so that the recesses in which the rods are normally prestressed no longer need to be injected by liquid cement.
Another advantage is that when asbestos material is used to enclose the rods and strings, the beam can withstand very high temperatures. ** WARNING ** End of DESC field may contain beginning of CLMS field **.
