Abstract

Węzeł kalenicowy ramy portalowej łączący dwa dźwigary charakteryzuje się tym, że zakończenia dźwigarów (3) i (4) w węźle kalenicowym usytuowane są w odległości równej długości pręta sztywnego dwuprzegubowego (5) usytuowanego pionowo w osi symetrii ramy portalowej, połączonego przegubowo za pomocą sworzni na obu jego końcach z zakończeniami dźwigarów (3) i (4), ponadto zakończenia dźwigarów (3) i (4) w węźle kalenicowym są połączone prętami wiotkimi (6) i (7) w sposób przegubowy za pomocą sworzni, pod kątami ostrymi po obydwu stronach osi symetrii ramy portalowej, przy czym odległości punktów połączenia prętów wiotkich (6) i (7) z zakończeniami dźwigarów (3) i (4) od osi symetrii ramy portalowej oraz ich kąty nachylenia są tak dobrane, że przecięcie przedłużenia osi podłużnej pręta sztywnego dwuprzegubowego (5) i jednego z prętów wiotkich dwuprzegubowych (6) znajduje się na osi symetrii ramy portalowej pod węzłem kalenicowym w odległości y<sub>01</sub> od punktu przecięcia osi ciężkości dźwigarów (1) i (2) wyznaczonej z zależności przedstawionej na wzorze (fig. A) gdzie: H jest wysokością słupa ramy portalowej, h<sub>1</sub> jest różnicą wysokości pomiędzy kalenicą ramy portalowej a wysokością słupa, a przecięcie przedłużenia osi podłużnej pręta sztywnego dwuprzegubowego (5) i przecięcie osi podłużnej drugiego z prętów dwuprzegubowych wiotkich (7) z osią symetrii ramy portalowej znajduje się na osi symetrii ramy portalowej nad węzłem kalenicowym w odległości y<sub>02</sub> od punktu przecięcia osi ciężkości dźwigarów (1) i (2) wyznaczonej z zależności przedstawionej na wzorze (fig. B) gdzie: H jest wysokością słupa ramy portalowej, h<sub>1</sub> jest różnicą wysokości pomiędzy kalenicą ramy portalowej a wysokością słupa.The ridge node of the portal frame connecting two girders is characterized by the fact that the ends of the girders (3) and (4) in the ridge node are located at a distance equal to the length of a rigid double-hinged bar (5) located vertically in the symmetry axis of the portal frame, jointly connected with pins on the both of its ends with the ends of the girders (3) and (4), moreover, the ends of the girders (3) and (4) in the ridge node are connected with flexible rods (6) and (7) in an articulated manner using pins, at acute angles on both sides of the symmetry axis of the portal frame, where the distances of the connection points of the flexible bars (6) and (7) with the ends of the girders (3) and (4) from the symmetry axis of the portal frame and their angles of inclination are selected in such a way that the intersection of the extension of the longitudinal axis of the rigid bar double-hinged rod (5) and one of the double-hinged flexible rods (6) is located on the symmetry axis of the portal frame under the ridge node at a distance y<sub>01</sub> from the point of intersection of the gravity axis of girders (1) and (2) determined from the relationship shown in the pattern (fig. A) where: H is the height of the column of the portal frame, h<sub>1</sub> is the difference in height between the ridge of the portal frame and the height of the column, and the intersection of the extension of the longitudinal axis of the rigid double-hinged rod (5) and the intersection of the longitudinal axis of the second double-hinged rod slender (7) with the symmetry axis of the portal frame is located on the symmetry axis of the portal frame above the ridge node at a distance y<sub>02</sub> from the point of intersection of the gravity axes of girders (1) and (2) determined from the relationship presented in the formula ( Fig. B) where: H is the height of the portal frame column, h<sub>1</sub> is the height difference between the portal frame ridge and the column height.
