Method for producing of a load-bearing grid, preferably a platform grid and/or deck grid and the load-bearing grid, preferably the platform grid and/or deck grid

摘要

the object of the application is a way of supporting bars, especially bars bridging and / or bars podestowej and grill carrier, especially bars bridging and / or grill podestowa.process for the production of supporting bars is characterised by that the wire rod in the form of a rod (1) first straightens and clears.after the rod is spłaszczaniu by rolling in the longitudinal smooth horizontal rollers (2), and subsequently obtained płaskownik (3) walcuje in the at least two frames (4,5) wykrojowych horizontal cylinders (6), whereby the tape płaskownika (3) runs through the guidewires.where any of the guidewires consists of at least two rolls about the vertical axis and at least two rolls about the horizontal axis.which is steerable are situated in the płaskownika (3) to the first cage (4) wykrojowych horizontal rollers (6), between the cages (4, 5) wykrojowych rollers (6),and the cylinders kalibrujących vertical cylinders (8) and at the output of the other cage (5) wykrojowych rollers (6) and (7) kształtownik output from the first cage (4) wykrojowych rollers (6),calibrated in the at least two vertical cylinders (8),i obtained profiles (7) arranged in a row is connected in the upper part of the longer sides of the intrinsically with transverse rows of structural elementsin the form of flat bars or wires, after which cuts them on a specific dimension and links inextricably with closure profiles.the supporting grate is characterized by the fact that part of the carrier are profiles (7) with variable thickness, where in the central part kształtownik (7) has a thickness and containing in the range 0.05 to 0.25 height h kształtownika (7), preferably the thickness is equal to 0.10 height h kształtownika (7), while the end sections kształtownik (7) has a thickness of b containing in the range of from 1.2 to 1.8 thickness and in the middle part, preferably thickness b kształtownika (7) on the end sections of equal thickness and 1.55 in the middle part.
