Description
Verfahren und Vorrichtung zur HerstellunG von Foruköp #2ern mit Hoh12äurnen .Die,3rfiiidung begrifft ein Verfahren und eine Vorrichtung zur Hürotellung von Formkörpe-on mit längs durchlaufenden -zylindi,ischen Hohlzäumen, insbesondei-e voii Hühlraumdeckenplatten aus Beton, unter Verwendung längsbeweglicher paralleler Ke2nrolu!e zur Hohlraumbildung.Method and device for the production of molds with hollow spaces. The 3rfiinung refers to a method and a device for the production of moldings with longitudinally continuous cylindrical hollow bridges, in particular hollow space ceiling plates made of concrete, using longitudinally movable, parallel hollow spaces! e for cavity formation.
Es ist behannt, Hohlvaumdeckenplatten aus Beton mit Yer--U'-it#ungsa.g.regaten herzustellen, die sich über die Produktionsfläche bewegen. Die Hohlraumbildung erfolgt dabei durch an jYerti.,uii[;saggregat anL#ebrachte kurze starre Kern-Dieses Herstellungsverfahren ermöglicht eine Frischentschalung der Hohlräume, ist jedoch nicht auf Produktionsverfahren, bei denen das Produkt den Produkt-ionsprozeß du2chläuft, die sogenannte Äggregatfließfertigung, übertragbar. It is reluctant to make concrete hollow vault slabs with Yer - U'-it # ungsa.g.regaten that move across the production area. The cavities are formed by a short, rigid core attached to jYerti., Uii [; sag aggregate.
Es ist in der 4gregatfließfertigung bekannt, Hohlraumdeckenplatten aus Beton derart herzustellen, daß die einzeln oder in benötigter Anzahl miteinander verbundenen Kernrohre bis zu einem gewissen Stadiuu der Betonerhärtung im Element verbleiben und dann mit Seilwinden oder ähnlichen AGGregaten gezogen werden, Dieses Verfahren ermöglicht zwar eine einwandfreie Herstellung der Botoneleftenteg bedingt jedoch durch die große Anzahl dei benötik#ten Kernrohre einen aufwendigen Formenpark. Außerdem entstehen beim Ziehen der Kernrohre Querrisse, uie auf Vakuum- u. Sogbildung zurückzuführen sind.It is known in the 4-unit flow production, cavity ceiling panels Manufacture from concrete in such a way that the individually or in the required number with each other connected core pipes up to a certain stage of concrete hardening in the element remain and then be pulled with winches or similar AGGregaten, this The process allows a flawless production of the Botoneleftenteg conditionally However, due to the large number of core tubes required, a complex range of molds. In addition, when pulling the core tubes, transverse cracks arise, due to the formation of vacuum and suction are due.
Es ist weiterhin bekannt, Hohlrau4ideckenplatten aus Beton Z .#a ' risch zu entschalen, indem die Kernrühre nach dem Verüich-UuxiUo-vorL;an-- durch ein I,c2nzieh,#erät geradlinig aus uerfi ton gezo-en weruen, DieS6L. Verfahren haftet der Nachteil ang daß wohl eine Frischentschalung erzielt wird$ zur ÜberviiiidunG der Haft-und Reibungskräfte jedoch eine t;roi;l#e Zugi#vaLZz bL#nG-Gigt wird und beiu Ziehvorgang ein sogenanntes -1-jachsac'x-#.en ae#-; Betons in den Hohlraum eintritt.It is also known to demoulding Hohlrau4ideckenplatten concrete Z # a 'driven by the Kernrühre after Verüich-UuxiUo-FLOW;. On-- by a I, c2nzieh, # et up instrument rectilinearly from uerfi ton Gezo-en weruen, DieS6L. The process has the disadvantage that a fresh demoulding is achieved $ to overcome the adhesive and frictional forces, however, a t; roi; l # e Zugi # vaLZz bL # nG-Gigt and during the pulling process a so-called -1-jachsac'x- # .en ae # -; Concrete enters the cavity.
Zweck der #=findun, ist est unter Vermeidung der anLieführten Nachteile die Herstellung von Hohlrauaaeckenplatben aus Beton im Aggregatfließverfahren mit 22ischentschalung der Elemente zu ermöglichen.The purpose of the # = findun is to avoid the disadvantages mentioned the production of Hohlrauaaeckenplatben from concrete in the aggregate flow process with 22 to enable demoulding of the elements.
Die Erfindung stellt sich die Aufgabe, die h#arnrohre, so auszubilden und den Ziehprozeß so zu jGestalten, da.13 eine Frischentschalung mit t;eringeai Kraftaufwand und ohne Beeinträchtigung der Betonqualität erfolgen kann.The object of the invention is to design the horn pipes in this way and to design the drawing process in such a way that a fresh demoulding with t; eringeai Effort and can be done without impairing the quality of the concrete.
Diese'Äufgabe wird erfindungsgemäß wie folgt gelöst: Die bekannten längsbevieglichen parallelen Nernrohre sind an dem längsverfahrbaren Kernziehgerät mit einem Antrieb drehbar angeordnet. Die Frischentschalung der HohlräuLe -erfolgt durch ein vorzugsweise paarweise geijenläufiges Drehen der Kernrohre mit gleichzeitiger ziehender Län"sbewegung derselben, Es wurde dabei gefunden, daß durch das gleiche vorzugsweise paarweise gegenläufige Drehen der KernrGhre ohne Längabewegung derselben und eine simultan erfolgende äußere oder innere Vibration eine sehr günstige Verdichtungswirkung erzielt wird.This task is solved according to the invention as follows: The known Longitudinally parallel core tubes are on the longitudinally movable core puller arranged rotatably with a drive. The fresh demoulding of the hollow spaces takes place by rotating the core tubes in parallel, preferably in pairs pulling longitudinal movement of the same, it was found that by the same rotating the core tubes in opposite directions preferably in pairs without moving them longitudinally and a simultaneous external or internal vibration has a very favorable compression effect is achieved.
Das erfindungsgemäße Verfahren mit der Vorrichtung beinhaltet wesentliche
technische und ökonomische Vorteile. Durch das Drehen der Kernrohre gleichzeitig
mit der üb-
lichen Vibrationsverd:Lehtung tritt eine Erhöhung der Verdichtung
im Bereich der Bewehrung- und der Stege ein, da das sich drehende Kernrohr wie eine
Verdichtungswalze wirkt,
