Description

Die bisher verwendeten ausziehbaren Stahlstützen zum Abstützen des Schalungsgerüstes für Betonkonstruktionen weisen den Nachteil auf, daß, falls die ineinanderschiebbaren Rohre mittels Schraubklemmen gegeneinander festgelegt werden, die Verbindung immer eine unsichere bleibt, da das Anziehen der Schrauben schwer kontrollierbar ist und durch den Verschleiß mit der Zeit immer unsicherer wird. Ferner verteuert eine stete Betätigung der Schrauben die Schalungsarbeit. Eine Verbesserung dieser Rohre ist durch eingelegte Konusse erfolgt, jedoch lassen auch diese Stützen noch einen Mangel bestehen. Es müssen im Betonbau die Stützen jeweils entsprechend dem Schaffungsfortgang um geringe Beträge, die oft nur einige 'Millimeter betragen, gehoben oder gesenkt werden. Desgleichen ist es beim Ausschalen der erhärteten Betonkonstruktion erforderlich, daß die Stütze nur ganz langsam, in Bruchteilen von Millimetern, gelöst wird, damit die Betonkonstruktion langsam in Spannung kommt.The extendable steel supports used to date to support the Formwork scaffolding for concrete structures have the disadvantage that if the telescopic pipes are fixed against each other by means of screw clamps, the connection always remains unsafe because it is difficult to tighten the screws is controllable and becomes more and more unsafe due to wear and tear over time. Furthermore, constant actuation of the screws makes the formwork work more expensive. An improvement this tube is made by inlaid cones, but these also leave supports there is still a defect. In concrete construction, the supports must be appropriate the progress of creation by small amounts, often only a few millimeters, be raised or lowered. It is the same when stripping the hardened concrete structure required that the support is only released very slowly, in fractions of a millimeter so that the concrete structure slowly comes into tension.

Zur Verbesserung dieser Stützen ist eine ausziehbare Stütze gewählt, welche Fig. i in der Seitenansicht, Fig. 2 im Querschnitt zeigt. Fig.3 stellt den Grundriß der Stütze mit Fußplatte dar, geschnitten in Höhe A-B, mit Blick nach unten in Pfeilrichtung. Das Rohr i am Kopfe der Stütze hat den gleichen Durchmesser wie das kurze Rohr 2 am Fuße der Stütze. Beide lassen sich über das mittlere Rohr oder den massiven Stahlzylinder 3 schieben. Das obere Rohr i trägt zur Aufnahme der Schalungskonstruktion einen beliebig ausgebildeten Kopf ,4. Das Fußrohr 2 ist auf eine Fußplatte 5 aufgeschweißt. Zur besseren Versteifung zwischen Fußrohr 2 und Fußplatte 5 sind dreieckige Stahlbleche 6 angeschweißt. Das Kopfrohr i ist mit mehreren durchgehenden Löchern 7 versehen. Diese Löcher sind in größeren Abständen längs des ganzen Rohres angeordnet. Das Mittelstück 3 hat am Kopfende mehrere durchgehende Löcher 8 in geringen Abständen. Bei Verschiebung des oberen Rohres i gegen das 'Mittelstück 3 lassen sich beide Rohre durch einen Splint 9, welcher jeweils durch sich gegenüberliegende Löcher 8 und 7 gesteckt wird, feststellen. Fußrohr 2 und Mittelstück 3 haben beide sich gegenüberliegende Ausnehmungen zur Aufnahme eines Keiles i i. Soll eine beliebige Höhe eingestellt werden, so läßt sich das obere Rohr i gegen das Mittelstück 3 verschieben, und zwar erfolgt die Grobeinstellung durch die weiter voneinander entfernten Löcher 7. Eine feinere Einstellung erfolgt über die wenigen. in kürzeren Abständen angebrachten Löcher 8, wobei Splint 9 zur Festlegung der beiden Rohre gegeneinander dient. Die feinste Einstellung erfolgt durch Eintreiben des Keiles i t am Fuße der Stütze. Beim Ausschalen erfolgt durch Lösen des Keiles ein langsames Senken und Lösen der Stütze, wie es für die Betonkonstruktion erforderlich ist.To improve these supports, an extendable support has been chosen, which Fig. i shows in side view, Fig. 2 in cross section. Fig.3 represents the Floor plan of the support with base plate, cut at height A-B, looking down in the direction of the arrow. The tube i at the head of the support has the same diameter as the short tube 2 at the foot of the support. Both can be accessed via the middle tube or slide the massive steel cylinder 3. The upper tube i supports the formwork construction a head of any shape, 4. The foot tube 2 is welded onto a foot plate 5. Triangular steel sheets are used for better stiffening between the foot tube 2 and the foot plate 5 6 welded on. The head pipe i is provided with several through holes 7. These holes are arranged at greater intervals along the entire length of the pipe. That Middle piece 3 has several through holes 8 at small intervals at the head end. When moving the upper tube i against the 'middle piece 3, both Pipes through a split pin 9, which each through opposite holes 8 and 7 is plugged in. Foot tube 2 and middle piece 3 both have one another opposing recesses for receiving a wedge i i. Should any Height can be adjusted, so the upper tube i can be moved against the middle piece 3, the coarse adjustment is carried out through the holes that are further apart 7. A finer adjustment is made over the few. attached at shorter intervals Holes 8, with split pin 9 used to fix the two tubes against each other. the The finest adjustment is made by driving in the wedge i t at the foot of the support. When stripping the formwork, the wedge is slowly lowered and loosened by loosening the wedge Support as required for the concrete structure.
