Description
Haltevorrichtung zur Auflagerung von Vorspanngliedern in Stahlbeton.Holding device for supporting tendons in reinforced concrete.
Bei Vorspannung von Betonteilen werden in : ~den Beton Drähte von hoher Festigkeit eingelegt, die vielfach zu mehreren als Spannglieder zusammengefaßt werden. Damit die rechnerisch ermittelten Spannungen in dem Spannbetonkörper auch richtig eingehalten werden, müssen die Vorspanndrähte eine genau bestimmte Lage erhalten. Zu diesem Zwecke werden die Vorspannglieder an der ohnehin vorhandenen schlaffen Bewehrung befestigt.When pre-stressing concrete parts, wires from high strength inserted, which are often combined into several as tendons will. This also applies to the calculated stresses in the prestressed concrete body are properly adhered to, the prestressing wires must be in a precisely defined position obtain. For this purpose, the tendons are attached to the existing one slack reinforcement attached.
In der Regel erfolgt die Verbindung der Vorspannglieder mit letzterer mit Hilfe senkrecht stehender, in der Regel als Bügel bezeichneter Stäbe, an welchen in der rechnerisch bestimmten Höhenlage horizontal liegende Stäbe befestigt Werden, auf denen die Spannglieder aufgelegt werden.As a rule, the tendons are connected to the latter with the help of vertical rods, usually referred to as stirrups, on which horizontally lying rods are attached at the calculated height, on which the tendons are placed.
Diese Verbindung der senkrechten Stäbe mit den horizontal liegenden Stäben muß zwei Bedingungen genügen : Sie muß einerseits genau in der vorgeschriebenen Höhe angebracht werden und andererseits so fest sein, daß sich der Querstab während des Betoniervorganges nicht verschieben kann.This connection of the vertical bars with the horizontally lying ones Bars must meet two conditions: On the one hand, it must be exactly as prescribed Height to be attached and on the other hand be so firm that the crossbar is during the concreting process cannot move.
Gemäß dem Muster wird diese Aufgabe durch eine Haltevorrichtung gelöst, die aus einer Klemme besteht, durch welche der zur Auflagerung der Spannglieder dienende horizontale Querstab fest mit dem senkrecht stehenden Längsstab (Bügel) verbunden wird. Diese Verbindung erfolgt erfindungsgemäß in einfacher Weise durch Zusammenpressen mittels einer Schraube, die eine genaue Einstellung und Regelung der Höhenlage des Querstabes ermöglicht. Im wesentlichen dient hierzu eine Schelle aus gelochtem oder gekerbtem Blech, durch welche der Anpreßdruck von der Schraube auf den Querstab übertragen wird.According to the pattern, this object is achieved by a holding device, which consists of a clamp through which to support the tendons serving horizontal cross bar fixed to the vertical longitudinal bar (bracket) connected. According to the invention, this connection is carried out in a simple manner Compression by means of a screw that allows precise adjustment and regulation the height of the crossbar allows. Essentially, a clamp is used for this made of perforated or notched sheet metal, through which the contact pressure from the screw is transferred to the crossbar.
Zwei Ausführungsbeispiele von Haltevorrichtungen nach dem Muster sind in der Zeichnung in schematischer Form dargestellt : Fig. 1 zeigt eine schaubildliche Ansicht einer Klemme, Fig. 2 eine Seitenansicht zu Fig. 1 Fig. 3 eine Draufsicht Fig. 4 zeigt in gleicher Darstellung wie Fig 1 ein anderes Ausführungsbeispiel für die Halteklemme.Two embodiments of holding devices according to the pattern are shown in schematic form in the drawing: FIG. 1 shows a diagrammatic view View of a clamp, FIG. 2 shows a side view of FIG. 1, FIG. 3 shows a plan view FIG. 4 shows, in the same representation as FIG. 1, another exemplary embodiment for the retaining clip.
In Fig. 1 bis 3 ist mit 1 die nach Art einer halben Rohrschelle ausgeführte Klemme bezeichnet, mit 2 der senkrechte Stab, mit 3 die Schraube, durch welche letzterer an den Querstab 4 gepreßt wird. Die Klemme 1, die aus einem gebogenen Blech oder auch aus einem Gußeisenstück bestehen kann, besitzt Bohrungen 5, durch welche der Querstab 4 gesteckt ist. In Fig. 1 to 3, 1 is executed in the manner of a half pipe clamp Terminal denotes, with 2 the vertical rod, with 3 the screw through which the latter is pressed against the cross bar 4. The clamp 1, which consists of a bent sheet metal or can also consist of a piece of cast iron, has holes 5 through which the Cross rod 4 is inserted.
Durch das Anziehen der Schraube 3 entsteht eine sehr feste Verbindung zwischen Querstab und Längsstab ; die Höhenlage der Verbindung kann in einfacher Weise durch Lockern der Schraube geregelt werden. Tightening the screw 3 creates a very firm connection between cross bar and longitudinal bar; the altitude of the connection can be made in simpler Way can be regulated by loosening the screw.
Fig. 4 zeigt ein ähnliches Ausführungsbeispiel, bei welchem jedoch anstelle der gestanzten Löcher 5 in den Seitenwangen der Klemme Kerben 7 getreten sind, in welche der Querstab 4 eingelegt werden kann. Fig. 4 shows a similar embodiment, but in which stepped notches 7 in place of the punched holes 5 in the side walls of the clamp are, in which the cross bar 4 can be inserted.
Anstelle von Klemmen aus Blech oder Gußeisen oder dgl. können auch Drahtklemmen verwendet werden, welche so gebogen sind, daß die Querstäbe in sie eingelegt werden können.Instead of clamps made of sheet metal or cast iron or the like. Can also Wire clips are used which are bent so that the cross bars into them can be inserted.
