A prefabricated retractable early warning unloading platform and its assembly and construction method

Abstract

The invention relates to an assembling type telescopic early-warning discharging platform and an assembling construction method thereof. The platform comprises a fixing part, a telescopic part, a transmission mechanism and an early-warning system, wherein the inner side of the fixing part is anchored to a structural floor slab, and the outer side of the fixing part is movably connected with the telescopic part through the transmission mechanism. The fixing part and the telescopic part are two intelligent wholes, are of a drawer type design, can stretch out and shrink in by virtue of rolling wheels and the transmission mechanism, so as to regulate the stretch-out length of the discharging platform; the discharging platform can easily shrink in or stretch out by virtue of the transmission mechanism, so that the stretch-out length of the discharging platform can be flexibly regulated, and the problem that a tower crane is difficult to operate when site operation conditions are limited, particularly a cornice is formed in an upper part structure is solved; the fixing part and the telescopic part are respectively of an assembling design, and components are connected through bolts, so that the platform is convenient to detach and transport; and by arranging the early-warning system, the tensile force on a steel wire rope is monitored in real time by virtue of a tension sensor, and sound-light alarm is given when the load exceeds a design limiting value, so that the accident is prevented.

Description

technical field [0001] The invention relates to an assembled unloading platform, in particular to an assembled and disassembled, expandable, acousto-optic early-warning unloading platform for material transportation in construction projects and its assembly and construction method . Background technique [0002] At present, the construction industry is developing rapidly, the building structure is becoming more and more mature, and there are more and more high-rise buildings and super high-rise buildings. As we all know, in the process of building construction, the transfer of materials between layers is generally carried out by vertical transportation tools, and the unloading platform has become an indispensable equipment for material transportation. In the construction of the secondary structure, the transportation of blocks, mortar, etc. also needs to be realized through the unloading platform. The use of the unloading platform significantly speeds up the progress of th...

AI Technical Summary

Problems solved by technology

The current types of unloading platforms mainly include floor-standing unloading platforms and cantilevered unloading platforms, and the cantilevered unloading platforms currently used are mainly welded on site, which not only has hidden dangers in safety, but also cannot be used for turnover. , under some special construction conditions, especially when there are overhanging eaves on the upper part of the building, the reverse transportation of materials will be greatly restricted, and the versatility is not strong
