The invention discloses an installation method for suspending a cable bridge under a high-altitude platform. The method comprises the steps of production and installation of a mobile platform, installation of the cable bridge, laying of a spring board and a safety rope, cable laying and subsequent disassembly and the like. The mobile platform comprises a steel tube erect rod, a cross beam, a skipping board, and a right-angle coupler, the steel tube erect rod comprises a left erect rod and a right erect rod, the bridge installation position is surveyed and mapped on site based on an operation map, the steel tube right-angle coupler is utilized to connect the left erect rod and the right erect rod, and the left erect rod, the right erect rod and a lifting lug at the upper end are connected through bolts, which facilitates assembly and disassembly. By means of the installation method for suspending the cable bridge under the high-altitude platform, the operation tasks of installation of the bridge and laying of cables in the bridge can be completed safely, efficiently, conveniently and with good quality, and the rental fee of all-around scaffolds is saved; the problem that in a conventional installation method, a passage is occupied for a long time is solved, and the installation method for suspending the cable bridge under the high-altitude platform has the advantages that the installation is convenient, the operation is safe, the operation cost is reduced, and the passage is not occupied and the like.

The invention relates to a formwork bar laying construction method, a combined type splitting formwork and a formwork quick connector. The method comprises the following construction steps that supporting racks are erected in a full hall mode; a bar paving mode is adopted for laying battens and rib beam formworks; the combined type splitting formwork is installed between rib beams in a laid mode; rib beam steel bars and top plate steel bars are bound; concrete is poured; a side formwork body and a bottom formwork body of the combined type splitting formwork are split; the beam bottom supporting racks and the rib beam formworks are disassembled. The method has the advantages that the battens and the rib beam formworks are laid in a bar mode, compared with an existing full formwork laid mode, the formwork area can be saved, the number of the adopted steel bars is reduced, and the amount of the adopted concrete is reduced; compared with an existing integral plastic formwork, formwork disassembling is finished at least 20 days earlier, the formwork circulation cycle is shortened, the formwork lease fee is saved, and the construction period is shortened greatly; the side formwork body and the bottom formwork body of the combined type splitting formwork can be disassembled fast, and rigidity of a whole supporting system is ensured after the formwork is disassembled.

Disclosed is a steel beam hydraulic lifting emplacing device on the top of silo structure building, which comprises a sliding formwork device and a hydraulic lifting system, and is characterized in that the sliding formwork lifting frames of the sliding formwork device are connected with an inside formwork, an outside formwork, and an operating platform, a scissors support is connected between twolifting frame upright columns, the sliding formwork lifting frame is also connected with a steel beam supporting frame, the steel beam support frame is connected with the steel beam on the top of thesilo to form a lifting integration, the hydraulic lifting system is utilized to be the lifting power system for the lifting integration, and the hydraulic lifting system is composed of a hydraulic jack, a support rod, a hydraulic console, and an oil circuit. The invention can rapidly, conveniently, reliably, and safely complete the construction task of mounting the steel beam on the top of the silo, without using large scale hoisting equipment, thereby avoiding the problems of difficult emplacement and lower efficiency of large scale hoisting equipment. The device of the invention can be widely applied to the hoisting and emplacement construction for the steel frame on the top of silo buildings.
