Boksprofil for kraner i letbygning designBox profile for cranes in lightweight design

FrembringelseGeneration

Frembringelsen vedrører bærende profiler (boksprofiler) for kraner (f.x. traverskraner, portalkraner, gantry kraner) i et letbygget design. En eller flere vægge {kropsplader) er helt eller delvist udført i trapezplader med eller uden ydeligere forstærkninger.The production relates to load-bearing profiles (box profiles) for cranes (eg traverse cranes, portal cranes, gantry cranes) in a lightweight design. One or more walls {body panels) are made wholly or partially in trapezoidal panels with or without additional reinforcements.

I det konkrete tilfælde er trapezplader anvendt som elementer der indgår i en bærende kranprofil. Iht. en yderligere udførelsesform af frembringelsen kan trapezplader i forskellige passende designs generelt anvendes til bærende bjælker eller bomme til eksempelvis bygningskonstruktioner, hvor der eksempelvis ønskes en vægtreduktion.In the specific case, trapezoidal plates are used as elements that form part of a load-bearing crane profile. Acc. In a further embodiment of the fabrication, trapezoidal panels in various suitable designs can generally be used for supporting beams or booms for example building structures, where, for example, a weight reduction is desired.

Kendt teknikPrior art

Ved kendte bærende konstruktioner ved kraner bruges i mange tilfælde såkaldte boksprofiler. Det er typisk af plader opsvejste profiler som danner et boks-/hulprofil. Profilet er typisk forstærket fx. ved hjælp af skot, ribber og/eller profiler. Vægten af et sådan profil er både forholdsvis høj og produktionsomkostninger for svejsearbejde er ligeledes høje.In known cases, crane profiles are used in many cases, such as box profiles. It is typically of sheet welded profiles that form a box / hole profile. The profile is typically reinforced e.g. using bulkheads, ribs and / or profiles. The weight of such a profile is both relatively high and production costs for welding work are also high.

Det tekniske problem, der skat tøsesThe technical problem of tax thawing

Med frembringelsen ønskes tilvejebragt - en bærende profil til kraner, som har en lavere vægt end kendte profiler opsvejst af plader reduceret arbejds- og svejseomfang og derved reducerede omkostningerWith the production, it is desired to provide - a load-bearing profile for cranes having a lower weight than known profiles welded by sheets reduced working and welding scope and thereby reduced costs

Den nye teknikThe new technique

Den nye teknik er: i stedet for vægge, f.eks. sidevægge af (forstærket) pladestål i siderne af profiler bruges trapezplader Trapezpladevægge kan være udformet på forskellige måder.The new technique is: instead of walls, e.g. side walls of (reinforced) sheet steel in the sides of profiles used trapezoidal panels Trapezoidal plate walls can be designed in different ways.

Den tekniske virkningThe technical impact

Konstruktioner som kendt teknik (eksempelvis boksprofiler af plader) kræver forholdsvis tykke plader og forstærkninger i form af skot, ribber og profiler for at undgå at plader folder under last.Constructions such as prior art (eg box profiles of sheets) require relatively thick sheets and reinforcements in the form of bulkheads, ribs and profiles to avoid sheets folding under load.

Trapezplader har pga. deres udformning relativ høj stivhed. Sidevæg kræver derfor ikke yderligere forstærkninger. Der kan vælges tyndere pladetykkelser til trapezplader.Trapezoidal plates have a relatively high stiffness due to their design. Side walls therefore do not require additional reinforcements. Thinner plate thicknesses can be selected for trapezoidal panels.

Dette medfører en mere simpel konstruktion og derved reducerede produktionsomkostninger side 1This results in a simpler design and thereby reduced production costs page 1
