System description, underfloor boxPlanning aid, screed-covered duct system08 UFS_Katalog_Middle_East_2010 / en / 13/12/2010 (LLExport_01150)Application with installation ductsUnderfloor boxes of type UZD-3/UGD-3 haveside walls, which have prepared installationopenings for sheet steel installation ducts.Underfloor connection boxes arecomponents of the screed-coveredinstallation duct system. They areinserted at intersections of screedcoveredduct sections or installationpipes and in duct runs and,depending on the expansion, allowaccess to the cables routed in theduct or in the pipes or the installationof electrical resources. Thebox bodies are available in thesystem sizes 250 and 350to match the screed-coveredducts. The box bodies possess aninternal height-adjustment with asetting range of + 55 mm.The minimum construction heightis 70 mm. For higher screed structures,box bodies of an appropriateheight (115 to 170 mm or 165to 220 mm) are used. Height compensationconstruction sets (raisingaids) allow underfloor connectionboxes to be converted to therequired height range. Dependingon the design, the box bodies caneither be closed using a mountingprotection lid (max. approved load75 kg) or with a 4 mm-thick blankinglid with a blind cover. Theopenings for the duct sections orinstallation pipes in the side wallsof the junction and branch boxesare prefabricated and can be easilycreated on the construction site.The boxes are principally suited foruse in floor structures with cementscreed, poured asphalt and anhydritescreed. The covers of the boxbodies can be decoupled from thebases after screed laying.Expansion of underfloor boxesUnderfloor boxes end flush with the top edgeof the screed. Function lids create installationopenings for flush-mount units or inspectioncovers.Expansion of underfloor boxesUnderfloor boxes end flush with the top edgeof the screed.
