Description

Przedmiotem wynalazkujest zlacze odcinków kabla pretowego, stosowany w technice spreza¬ nia elementów betonowych.Znane zlacze odcinków kabla pretowego stanowi tuleja gwintowana, która laczy odcinki proste kabli pretowych zakonczonych gwintem. Wada takiego zlacza jest mozliwosc prowadzenia kabli pretowych tylko w linii prostej, badz lukowo o stalym promieniu.Zlacze wedlug wynalazku wyróznia sie tym, ze zawiera przegub, w którym obrotowo sa osadzone jednym koncem co najmniej dwa odcinki kabli pretowych z osadzonymi na stale slizgami lukowymi.Korzystne jest jesli przegub sklada sie z co najmniej dwóch pierscieni.Zgodnie z wynalazkiem zlacze zwieksza zakres stosowania kabli pretowych. Umozliwia stosowanie kabli pretowych o dowolnej lamanej trasie zarówno jako kable odkryte w konstruk¬ cjach budowlanych zelbetowych jak i stalowych. Ponadto przez zastosowanie przegubu uzyskano mozliwosci zmiany polozenia odcinków kabli pod obciazeniem.Przedmiot wynalazkujest przedstawiony w przykladzie wykonania na rysunku, który na fig. 1 przedstawia zlacze odcinków kabla pretowego w dzwigarze zelbetowym, na fig. 2 — przegub w ujeciu z boku, zas na fig. 3 — przegub w widoku wzdluz odcinków kablowych.Jak pokazano na fig. 1 rysunku, dzwigar zelbetowy ljest sprezony w pasie dolnym trzema kablami pretowymi 2, 2', 2" polaczonymi pomiedzy odcinkami kabli 2, 2', 2" przegubami 3, 3', a konce skrajnych odcinków kabli 2, 2" sa zakotwione na czolach dzwigara 1 zakotwieniami 4, 4'.Zastosowanie przegubów 3,3' pozwala na prowadzenie odcinków kabli pretowych 2,2', 2" w dolnym pasie przekroju dzwigara zelbetowego 1, narazonego najbardziej na sily rozciagajace.Przeguby 3, 3', sa podparte na wspornikach 7, 7\ Uwidoczniony na fig. 2 i fig. 3 rysunku przegub 3, 3' zlozony jest z dwTóch pierscieni 3a, 3a\ wewnatrz których sa osadzone odcinki kabli pretowych 2,2', 2" zakonczone slizgami lukowymi 6, 6', które stanowia nakretki osadzone na nagwintowanych koncach odcinków kabli 2, 2', 2".2 147195 Zastrzezenia pa t e n t o w e 1. Zlacze odcinków kabla pretowego, znamienne tym, ze zawiera przegub (3, 3'), w którym obrotowo sa osadzone jednym koncem co najmniej dwa odcinki kabli pretowych (2, 2', 2") z osadzonymi na stale slizgami lukowymi (4, 4'). 2.

Naklad 100 egz.Cena 400 zl PLThe subject of the invention is a joint between sections of a cable tie, used in the technique of tensioning concrete elements. A known joint between sections of a cable tie is a threaded sleeve which connects straight sections of threaded cables. The disadvantage of such a connector is the possibility of running the rod cables only in a straight line or with a fixed radius. The connector according to the invention is distinguished by the fact that it includes a joint in which at least two sections of rod cables with permanently mounted arch slides are rotatably mounted at one end. It is advantageous if the joint comprises at least two rings. According to the invention, the joint increases the range of use for the cable. It enables the use of cable cables with any broken route, both as exposed cables in reinforced concrete and steel building structures. In addition, the use of a joint provides the possibility of changing the position of the cable sections under load. The subject of the invention is presented in the example of embodiment in the drawing, which in Fig. 1 shows the joint of the cable sections in the reinforced concrete girder, in Fig. 2 - the joint in the side view, and in Fig. 3 - joint in the view along the cable sections. As shown in Fig. 1 of the figure, the reinforced concrete girder 1 is prestressed in the lower chord with three rod cables 2, 2 ', 2 "connected between the cable sections 2, 2', 2" with joints 3, 3. ', and the ends of the extreme sections of cables 2, 2 "are anchored on the fronts of the girder 1 with anchors 4, 4'. The use of 3.3 'hinges allows for running sections of 2.2', 2" cable cables in the lower section of the reinforced concrete girder 1, Joints 3, 3 ', are supported on brackets 7, 7 \ The joint 3, 3' shown in Fig. 2 and Fig. 3 of the drawing is composed of two rings 3a, 3a \ inside which are embedded cable sections pr 2.2 ', 2 "cables terminated with 6, 6' slots, which are nuts mounted on the threaded ends of the cable sections 2, 2 ', 2" .2 147195 Patent claims 1. Joint of the cable sections, characterized by a joint (3, 3 '), in which at least two sections of rod cables (2, 2', 2 ") are pivotally mounted at one end with permanently mounted hatch slides (4, 4 '). 2. Connector according to claim 2. The apparatus of claim 1, characterized in that the joint (3, 3 ') consists of at least two rings (3a, 3a'). 67 ^ FIG. 3 Printing House of the People's Republic of Poland.
