Description
Verfahren zur Herstellung von Eisenbetonrippendecken mit vorher angefertigten Rippenträgern. Es ist bekannt, Eisenbetonrippendecken -in der Weise herzustellen, daß vorher hergestellte Rippenträger in Abständen verlegt werden, wonach der die Rippenträger verbindende Druckgurt, die Platte, auf einer Schalung zwischen oder auf die Köpfe der Rippenträger geschüttet wird.Process for the production of reinforced concrete rib ceilings with previously made Ribbed straps. It is known to produce reinforced concrete rib ceilings in the manner that previously made rib beams are laid at intervals, after which the Ribbed support connecting pressure belt, the plate, on a formwork between or is poured on the heads of the rib supports.
Es .ist ferner bekannt, die in der Werkstatt hergestellten Eisenbetonrippenträger zum Schutze gegen Beschädigungen, beim Versenden, Aufziehen und Versetzen mit einem abnehmbaren Druckgurt oder sonstigen abnehmbaren Versteifungsplatten zu verbinden.It. Is also known, the reinforced concrete rib girders produced in the workshop to protect against damage when shipping, opening and moving with one to connect removable pressure belt or other removable stiffening plates.
. Demgegenüber bildet den Gegenstand der Erfindung ein Verfahren zur Herstellung von Eisenbetonrippendecken mit vorher hergestellten Rippenträgern, nach welchen diese während der Handhabung, d. h. entweder schon bei der Herstellung oder erst für die Versendung und für das Versetzen am Bau; durch seitlich befestigte Versteifungen verstärkt werden, die nach Lösen sämtlicher oder nur der mittleren Befestigungsmittel bei der Herstellung der Decke als Träger der Schalung für den Druckgurt der Rippendecke dienen. Hierdurch werden einerseits die Versteifungsplatten verschiedenen Zwecken nutzbar gemacht und dadurch besser ausgenutzt, anderseits schützen sie die schwachen, durch den Druckgurt noch nicht verstärkten. Rippenträger gegen Mehrbeanspruchungen.. In contrast, the subject matter of the invention is a method for Manufacture of reinforced concrete rib ceilings with previously manufactured rib girders, according to which these during handling, d. H. either during production or only for dispatch and for moving on site; by laterally attached Stiffeners are reinforced after loosening all or only the middle Fastening means in the manufacture of the ceiling as a support for the formwork Pressure belt of the ribbed ceiling are used. As a result, on the one hand, the stiffening plates made usable for various purposes and thus better exploited, on the other hand protect the weak ones that have not yet been reinforced by the pressure belt. Ribbed support against increased loads.
Ein Ausführungsbeispiel eines solchen Verfahrens ist in der Eig. i im Quers:chnittdurch eine Eisenbetonrippendecke dargestellt. Die Fig.2 zeigt eine abgeänderte Ausführungsart und die Fig. 3 einen verstärkten Rippenträger in der Seitenansicht.An embodiment of such a method is in the prop. i Cross-section through a ribbed reinforced concrete ceiling. The Fig.2 shows a modified embodiment and FIG. 3 shows a reinforced rib support in the Side view.
Bei der Herstellung der Decke werden die in Abständen verlegten, vorher angefertigten Eisenbetonrippenträger i durch die im Bau hergestellten Platten 3 miteinander verbunden. Es werden. vorzugsweise Eisenbetonträger i gewählt, die keinen oder nur einen kleinen Druckflansch (siehe in der Fig. i den mit gestrichelten Linien angedeuteten Druckflansch 2), also im wesentlichen Stegform haben und deren. Druckflansch die Platte 3 bildet. Der Trägerbeton wird wie üblich durch die herausragenden Bügel 5 mit dem Druckgurtbeton innig verbunden.When making the ceiling, the spaced layers are laid beforehand manufactured reinforced concrete rib girders i through the slabs manufactured in the building 3 connected with each other. It will. preferably ferro-concrete girders i chosen that do not have any or just a small pressure flange (see in Fig. i the one with dashed lines indicated pressure flange 2), so essentially have a bar shape and their. Pressure flange the plate 3 forms. The carrier concrete is, as usual, through the protruding brackets 5 intimately connected with the compression belt concrete.
Die Rippenträger i werden gegen Beanspruchungen während der Handhabung .durch seitlich daran befestigte (angeschraubte) Balken: 13 gesichert, .die zweckmäßig auch schon als Schalung bei der Herstellung der Rippenträger dienen. Diese Balken 13 haben zweckmäßig die Form von hochkantig gestellten Balken, die den Träger fast vollständig umschließen und ihn wirksam gegen Bruch oder Beschädigung beim Versenden, Aufziehen und Versetzen schützen.The rib girders i are secured against stresses during handling .by laterally attached (screwed) beams: 13, which also serve as formwork during the manufacture of the rib girders. These bars 13 are expediently in the form of bars placed on edge, which almost completely enclose the carrier and effectively protect it against breakage or damage during shipping, mounting and moving.
Diese Sicherungsbalken werden bei der Herstellung der Decke nunmehr derart benutzt, daß .die Rippenträger möglichst entlastet werden. Zu diesem Zweck werden die Befestigungsmittel (Verschraubungen) der Balken 13 am Rippenträger i vor dem Aufbringen des Druckgurtbetons entweder sämtlich oder bis auf die Schrauben; 16 in der Nähe der Auflagerenden des Rippenträgers gelöst. Die Balken 13 tragen dann die zur Herstellung der Platten 3 dienende Schalung 8 entweder unmittelbar (Fig. 2) oder z. B. mittels seitlicher Auflagerleisten 15.These safety bars are now used in the manufacture of the ceiling used in such a way that .the rib girders are relieved as much as possible. To this end the fasteners (screw connections) of the beams 13 on the rib beam i before applying the compression chord concrete either all or except for the screws; 16 solved in the vicinity of the support ends of the rib beam. The beams 13 carry then the formwork 8 used to produce the panels 3 either directly (Fig. 2) or e.g. B. by means of lateral support strips 15.
Durch diese Verwendungsart der Balken 13 wird erreicht, daß der Rippenträger i währen4 der Deckenherstellung nur sein Eigengewicht und bei Durchführung des Druckgurtes über den Träger den darüber lagernden Beton zu tragen hat, während der Plattenbeton 3 im wesentlichen von, den auf den Widerlagern ruhenden . Balken 13 getragen wird, wenn sämtliche Befestigungsmittel gelöst werden. Werden nur die mittleren Schrauben gelöst, so wird die Last erst in der Nähe der Auflagerenden,der Rippenträger auf diese übertragen (Fig.3). Das von den Rippenträgern aufzunehmende Moment ist also sehr klein. Die Rippenträger werden daher bei der Herstellung der Decke möglichst entlastet und in wenig belastetem Zustand, also auch bei wenig gespanntem Zugeisen in den Plattenbeton einbetoniert.This type of use of the beams 13 ensures that the rib support During the manufacture of the ceiling, only its own weight and when the pressure belt is being carried out has to carry the overlying concrete via the girder, while the slab concrete 3 essentially from those resting on the abutments. Beam 13 is supported, when all fasteners are loosened. Will only be the middle screws released, the load is only in the vicinity of the support ends, the rib girder on these transfer (Fig. 3). So the moment to be absorbed by the rib supports is tiny. The rib beams are therefore as possible in the manufacture of the ceiling relieved and in a lightly loaded condition, i.e. even with a slightly tensioned pull bar concreted in the slab concrete.
Die Balken 13 erfüllen. hiernach einen mehrfachen Zweck: Erstens schützen sie die Rippenträger beim Versenden,- Aufziehen und Versetzen gegen örtliche Beschädigungen und unzulässige Beanspruchung, insbesondere bei umgekehrter oder flacher Läge. Zweitens dienen sie nach Lösen der mittleren Verbindungsmittel als Träger der Plattenschalung und schützen so die. schwachen, durch den Druckgurt des Plattenbetons noch nicht verstärktenTragrippengegenMehrbeanspruchung und somit auch gegen Mehrbeanspruchung der Zugeisenoinlage. Daher können die Rippenträger bei diesem Arbeitsverfahren: geringere Abmessungen und schwächere Bewehrung erhalten, womit auch eine Ersparnis an Baustoff und Arbeit und ein geringeres Gewicht gegeben ist. Drittens können die Balken auch noch als Schalung bei der Herstellung der Rippenträger selbst benutzt werden.The bars 13 meet. hereafter a multiple purpose: First, to protect they the rib beams when shipping, - pulling up and moving against local damage and inadmissible loads, especially if they are upside down or flat. Secondly After loosening the middle fasteners, they serve as a support for the panel formwork and protect them. weak, not yet due to the pressure belt of the slab concrete reinforced support ribs against increased stress and thus also against increased stress the train iron insert. Therefore, with this working method, the rib beams can: Get smaller dimensions and weaker reinforcement, which also means savings of building material and work and a lower weight is given. Third, the Beams are also used as formwork in the manufacture of the rib girders themselves will.
