Opfindelsen angår en underform til fremstilling af betontagsten ved strengpresning, hvilken underform er af den i krav l's indledning nærmere angivne art.The invention relates to a sub-mold for the production of the concrete roof by compression, which is of the kind specified in the preamble of claim 1.
5 Kendte underformer af denne art tilføres af et transportbånd i form af en uafbrudt streng til udstøbnings- og fortætningsudstyr, hvori der på underformene anbringes et lag frisk betonmasse. Dette lag bliver derpå mekanisk fortættet og profileret til dannelse af de ønskede form-10 legemer.5 Known sub-molds of this kind are supplied by a conveyor belt in the form of an uninterrupted string for casting and densification equipment, in which a layer of fresh concrete is applied to the sub-molds. This layer is then mechanically densified and profiled to form the desired mold bodies.
Fra AT-patentskrift nr. 180.886 kendes en underform af den indledningsvis nævnte art, hvori underskallen er udformet med to i længderetningen gennemgående, rendeformede fordybninger, der befinder sig under flade områder i 15 overskallen på begge sider af den i midten forløbende vulst. Ved de flade områders tværkanter er der udskåret nedadbøjede pladeflige svarende til fordybningerne til dannelse af endevægge i formkamre til fremstilling af teglnæser. Sammen med endeplader, der er påsvejset mellem 20 formkamrene, skal endevæggene desuden afstive underformen i tværretningen. Da der imidlertid findes gennemgående hulrum under de i overskallen langsgående vulster og over de i underskallen udformede rendeformede fordybninger mellem de respektive endevægge, vil en sådan underform, 25 dersom den kun er fremstillet af tyndt plademateriale, i dette område ikke kunne modstå de ovenfra virkende, høje sammenpresningskræfter.From Patent Specification No. 180,886 there is known a sub-mold of the type mentioned in the beginning, in which the lower shell is formed with two longitudinal, groove-shaped recesses which lie beneath flat areas in the upper shell on both sides of the middle extending bead. At the transverse edges of the flat areas, downwardly bent plate tabs are cut corresponding to the recesses to form end walls in mold chambers for the manufacture of brick noses. In addition, with end plates welded between the 20 mold chambers, the end walls must support the sub-mold in the transverse direction. However, since through-cavities exist beneath the upper longitudinal bumps and above the gutter-shaped recesses between the respective end walls, such a sub-mold, if only made of thin sheet material, will not be able to withstand the above acting, in this area. high compressive forces.
Det er på denne baggrund opfindelsens formål med enkle midler og på rationel måde at tilvejebringe en særlig let 30 og stabil underform, der både kan tåle de ovenfra på formen virkende høje sammenpresningskræfter og er effektivt afstivet imod bøjning i længde- og tværretningen, og som også er egnet til fremstilling af betontagsten af den art, der er udformet med en midterfalsbue og en vandfals 35 henholdsvis en dækfals ved længdekanterne.It is in this context the object of the invention with simple means and in a rational way to provide a particularly light and stable sub-mold, which can both withstand the high compressive forces acting from the top and is effectively stiffened against longitudinal and transverse bending, and which also is suitable for the manufacture of the concrete roof tiles of the type formed with a center fold arch and a water drop 35 and a cover roll at the longitudinal edges, respectively.

Det angivne formål opnås ved en underform, som ifølge opfindelsen tillige udviser de i krav l’s kendetegnende del angivne træk. Herved opnås, at sikkerne støtter 5 overskallen imod underskallen, så formen kan tåle selv meget høje sammenpresningskræfter, og samtidigt hermed bevirker sikkerne henholdsvis vulsterne en afstivning i tværretningen henholdsvis længderetningen, der gør formen særdeles bøjningsstiv i disse retninger.The stated object is achieved by a subform which according to the invention also exhibits the features of claim 1. This ensures that the safe supports the upper shell against the lower shell, so that the mold can withstand even very high compressive forces, and at the same time, the secure and the beads respectively provide a stiffening in the transverse direction and the longitudinal direction, which makes the mold extremely bending stiff in these directions.
10 Ved den i krav 2 angivne udførelsesform opnås en for de fleste anvendelser tilstrækkelig stabilitet med en rimelig materialeøkonomi.In the embodiment of claim 2, stability is obtained for most applications with a reasonable material economy.
Ved den i krav 3 angivne udførelsesform undgås, at formen beskadiges af fremføringsknasterne på transportbåndet, 15 idet kraften fra disse knaster optages og fordeles af indsatsdelen.In the embodiment according to claim 3, the mold is prevented from being damaged by the conveyor lugs on the conveyor belt, as the force from these lugs is absorbed and distributed by the insert part.
Den i krav 4 angivne foranstaltning tjener dels til yderligere forbedring af underformens formstabilitet, dels til støjdæmpning, og dels til korrosionsbeskyttelse i 20 hulrummet mellem overskallen og underskallen.The measure of claim 4 serves partly to further improve the mold stability of the sub-mold and partly to noise attenuation and partly to corrosion protection in the cavity between the upper shell and the lower shell.
