Abstract

Belka nośna o konstrukcji skrzynkowej, z wewnętrznymi wzmocnieniami, ograniczona czterema płytami zewnętrznymi górną (1) i dolną (2), usytuowanymi poziomo, połączonymi nierozłącznie z dwoma płytami bocznymi (3, 4) usytuowanymi pionowo, posiadająca nadto wewnętrzne prostopadłościenne płyty wzmacniające, dwie (6, 8) usytuowane poziomo i dwie (9, 10) usytuowane pionowo, z których krawędzie górne i dolne wewnętrznych płyt (9, 10) usytuowanych pionowo posiadają występy zamocowane metodą spawania w przelotowych otworach górnej (1) i dolnej (2) płyty zewnętrznej. Krawędzie boczne wewnętrznych płyt (6, 8) są wyposażone w występy zamocowane metodą spawania w przelotowych otworach wewnętrznych płyt (9, 10). Belka jest wyposażona nadto w dodatkowe wewnętrzne elementy wzmacniające (5, 7, 11, 12), które stanowią prostopadłościenne ażurowe płyty z otworami o kształcie heksagonalnym, o gęstości otworów zmiennej wzdłuż tych płyt na całej ich długości i największej gęstości otworów w połowie szerokości tych płyt, z których dwie ażurowe płyty (11, 12) są usytuowane pionowo po jednej między zewnętrznymi (3, 4) i wewnętrznymi (9, 10) płytami belki usytuowanymi pionowo, wzdłuż tych płyt na całej ich długości oraz dwie ażurowe płyty (5, 7) są usytuowane poziomo po jednej między zewnętrznymi (1, 2) i wewnętrznymi (6, 8) płytami belki usytuowanymi poziomo, na całej długości belki lub tylko w pobliżu jej końców. Górne krawędzie ażurowych płyt (11, 12) są przymocowane do górnej płyty zewnętrznej (1) belki, zaś dolne krawędzie tych ażurowych płyt (11, 12) do dolnej zewnętrznej płyty (2) belki. Górne krawędzie ażurowej płyty (5) usytuowanej poziomo między górnymi poziomymi płytami belki (1, 6) są przymocowane do górnej zewnętrznej płyty (1) belki, zaś dolne krawędzie tej ażurowej płyty (5) do górnej wewnętrznej płyty (6) belki. Górne krawędzie ażurowej płyty (7) usytuowanej między dolnymi płytami belki (2, 8) są przymocowane do dolnej wewnętrznej płyty (8) belki, zaś dolne krawędzie tej ażurowej płyty (7) do dolnej zewnętrznej płyty (2) belki.A box-shaped load-bearing beam with internal reinforcements, bounded by four outer plates: upper (1) and lower (2), arranged horizontally, inseparably connected to two side plates (3, 4) arranged vertically, and further comprising two inner rectangular reinforcing plates (6, 8) arranged horizontally and two (9, 10) arranged vertically, of which the upper and lower edges of the inner plates (9, 10) arranged vertically have projections fastened by welding in the through holes of the upper (1) and lower (2) outer plate. The side edges of the inner plates (6, 8) are equipped with projections fastened by welding in the through holes of the inner plates (9, 10). The beam is further equipped with additional internal reinforcing elements (5, 7, 11, 12), which are cuboid openwork plates with hexagonal openings, with a variable hole density along these plates along their entire length and the highest hole density at half the width of these plates, of which two openwork plates (11, 12) are located vertically, one each between the outer (3, 4) and inner (9, 10) beam plates located vertically, along these plates along their entire length, and two openwork plates (5, 7) are located horizontally, one each between the outer (1, 2) and inner (6, 8) beam plates located horizontally, along the entire length of the beam or only near its ends. The upper edges of the openwork plates (11, 12) are attached to the upper outer plate (1) of the beam, and the lower edges of these openwork plates (11, 12) to the lower outer plate (2) of the beam. The upper edges of the openwork plate (5) located horizontally between the upper horizontal plates of the beam (1, 6) are attached to the upper outer plate (1) of the beam, and the lower edges of this openwork plate (5) to the upper inner plate (6) of the beam. The upper edges of the openwork plate (7) located between the lower plates of the beam (2, 8) are attached to the lower inner plate (8) of the beam, and the lower edges of this openwork plate (7) to the lower outer plate (2) of the beam.
