DEVICE FOR LIFTING SLIDING MOLDS ALONG STEEL BARS FOR THE CONSTRUCTION OF CONCRETE BUILDINGS ETC.

摘要

AbstractIn the device for lifting sliding molds at steel barsaccording to the sliding mold system for the productionof concrete buildings etc. having variable cross sectionsof straight and curved walls, use is made of a supportscaffolding comprising hoists operating mechanically orhydraulically to lift it. To this effect, a system of beamsmounted in star form, of yoke structures is provided which carryslide molds displaceable in radial direction. In addition,adjusting of the radially movable yoke structures is performedby a ring-shaped frame-work construction which consists ofa frame-work being repeated per support unit each, andwhich, along the periphery of the building is connectedtangentially and arranged in ring symmetry.The frame system and the control device for adjusting andguiding the sliding molds comprises a yoke structure(6) which has a traverse (11) provided below the hoist (2)and secured thereto, and a traverse (14) extending above thehoist (2). The inner and the outer yoke post (7,8) areflexibly connected to the traverses (11,14).Moreover, the ends of the traverses at the side of theinner yoke post (7) are flexibly connected by the latterand the free end of the upper traverse (14) with theouter yoke post (8) by a brace (18) adjustable in length.In this connection, the adjustable parallelogram-shapedyoke structure (6) formed by the traverses (11,14) andof the yoke posts (7,8) is supported to be displaceablein total along a star beam (27). By this means, the yokeposts of the yoke structure are in parallel to the axisof the wall under erection, and the lower and upper traversesof the yoke structures as well as the traverse of theworking and hanging platform may be easily maintained toextend in horizontal direction.(Fig.1.)
