prefabricated case beam, belong to the site operation apparatus field, include the backform that places the middle part, two side forms that are positioned at both sides and are hinged with backform, the side form below has the hinged angle mould of bearing pin respectively, be provided with hydraulic jack between its backform and the side form, also be provided with hydraulic jack between side form and the angle mould, the top, side, the middle part of the re-entrant cavity that angle mould forms is provided with away cross girders, it is supported on the special shoulder pole type case beam in baseplane by roller, and is provided with anchoring rod between the baseplane.The installation of inner membrance, shift out operation and simplify, simplified supporting form in the beam simultaneously, adopt the hydraulic pressure folding and retraction, needn't manually fold, pass through hydraulic-driven, template reaches the purpose of reduced volume with folding mode, the small space that overall time forms because of thickening web, top board and base plate at beam-ends by the case beam.4, " box girder inner formwork " application (patent) number CN 200720089937.6 the utility model discloses a kind of box girder inner formwork, its top template two side ends is hinged with the upper end of an epipleural respectively, the lower end of two epipleurals is hinged with the upper end of a lower side panel respectively, vertically whenever keep at a certain distance away along described top template a upright beam and jacking cylinder are set, all jacking cylinders upper end all with described top template longitudinal centre line on lower surface hinged, all jacking cylinder lower ends are installed on separately the upright beam, be provided with guide rail and roller between all upright beams and the support, top template vertically some horizontal tangent planes is provided with, following telescopic oil cylinder, last telescopic oil cylinder is arranged between top template and the epipleural, following telescopic oil cylinder is arranged between epipleural and the lower side panel, top template vertically some horizontal tangent planes is provided with, lower supporting rod, last strut is arranged between top template and the lower side panel, and lower supporting rod is arranged between epipleural and the upright beam.The utility model is simple in structure, have the advantage that system beam speed is fast, labour intensity is little, mechanization degree is high.
Yet these four patents have all adopted the hydraulic jack system, though a series of advantage is all arranged, at external mold Zhi Haohou, the remaining space in the external mold is limited, so concrete execution conditions are limited, as: the people can't enter at all, equipment also can't set up.For the narrow and small case beam of clear space in the beam body, especially be subjected to the restriction of equipment volume, hydraulic mechanism size, above-mentioned patented method and structure are inapplicable.
