The utility model content
Technical problem to be solved in the utility model provide a kind of safe, take tear convenient and swift, high efficiency open, hoistway construction circulation turnover operating platform that the turnover that can circulate is used.
In order to solve the problems of the technologies described above, the hoistway construction circulation turnover operating platform that the utility model provides, comprise the crossbeam in the reserved opening that is located on the shear wall, be provided with the operating platform that adopts steel tube fastener to set up by vertical rod, horizon bar and bridging at described crossbeam, around described operating platform, be provided with the crown wall spare with jail, well enclosure top, middle part at the described horizon bar at the top of described operating platform is welded with hanger, is provided with safety net at the medium position of described operating platform.
Be provided with the reinforcing bar anchor point that docks with described vertical rod at described crossbeam.
Described reinforcing bar anchor point is the high A20 reinforcing bar of 20mm anchor point.
Described crossbeam is the 12# i iron.
Adopt the hoistway construction circulation turnover operating platform of technique scheme, offer reserved opening at shear wall, reserved opening internal frame crossbeam, establish by vertical rod, horizon bar and bridging at crossbeam and to adopt steel tube fastener to set up the high operating platform of three floors, around operating platform, stretch out crown wall spare and jail, well enclosure top, guarantee the stability of operating platform, at the middle part of top horizon bar welding hanger, so that tower crane lifting turnover, medium position at operating platform arranges safety net, guarantee personnel's job safety, prevent high pendant.Crossbeam guarantees that at the high A20 reinforcing bar of vertical rod place welding 20mm anchor point operating platform is unshift.The every construction one deck turnover of operating platform once.
Adopt the hoistway construction circulation turnover operating platform of technique scheme, simple to operate, technical essential is grasped easily.Compare with traditional hoistway handling frame, economize on resources, save trouble, save time, the saving of labor, safe and reliable, drop into low, good in economic efficiency.
In sum, the utility model be a kind of safe, take tear convenient and swift, high efficiency open, hoistway construction circulation turnover operating platform that turnover is used and simple in structure, the energy-conserving and environment-protective of can circulating, the job site that is worthy of popularization are used.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, reserve 100 * 160 reserved opening 4 at the shear wall of hoistway both sides, treat that its intensity reaches 20MPa when above, penetrate 12# i iron 1 as crossbeam, on 12# i iron 1, weld the high A20 reinforcing bar of 20mm anchor point 2 apart from the inboard 300mm of hoistway shear wall place, by vertical rod 5, the operating platform that horizon bar 6 and bridging 7 adopt steel tube fastener to set up, operating platform is set up three story heights, the lower end docking of the vertical rod 5 of operating platform is inserted on the A20 reinforcing bar anchor point 2, guarantee that operating platform is unshift, crown wall bar 3 is set around operating platform to be fixed with the borehole wall, guarantee the stability of operating platform, at the hanger 8 of the top of operating platform horizon bar middle part welding A20 reinforcing bar, so that lifting during the operating platform turnover.Need to check the screw-down torque of each fastening bolt after operating platform is set up and finished, guarantee to meet code requirement.Be provided with safety net 9 at the middle part of operating platform, be fixed on the horizon bar 6 of operating platform, prevent that the eminence of people and thing from falling down from the building.
The complete one deck turnover of the every construction of operating platform once, crown wall spare 3 around unclamping first during turnover, rear operating platform being hung with tower crane rises one deck, the workman takes out of 12# i iron 1 through walls and forwards last layer week to and install, operating platform is installed on the 12# i iron 1 that fixes with tower crane again, crown wall spare 3 around the operating platform is fixed, namely finished the once turnover of operating platform.
