FIELD: construction. ^ SUBSTANCE: scaffolding includes support-adjustment accessories in the form of jack screws and support structure that bears casing bottom and consists of longitudinal and transverse beams. Jack screws in span and at the ends of bridge span are fixed on side walls and diaphragms of the main beams with the help of T-shaped cantilever tables equipped with vertical tubular elements, where screws of jacks are freely installed, having spherical head in upper part with a cup freely placed on it and having a location plate with a reverse spherical surface. On upper plane of cup there are transverse beams of support structure installed, which are fixed on it with the help of side limiters in the form of pins and L-shaped stops, and at the end of vertical tubular elements of T-shaped cantilever tables there are flanges arranged, on which jack screw nut rests. ^ EFFECT: expansion of technological resources of scaffolding. ^ 3 cl, 3 dwg |
