Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of telescopic steel platform for elevator shaft, and this steel platform can promote with tower crane, so can not take a large amount of constructional materialss, meanwhile, has reduced the probability that security incident occurs.
For achieving the above object, the technical solution of the utility model is: for the telescopic steel platform of elevator shaft, comprise the steel pipe girder of rectangle, inferior girder steel and operating desk, wherein, be provided with two parallel steel pipe girders, inferior girder steel and steel pipe girder connect and compose the framework of rectangle, and steel pipe girder two ends are equipped with suspension ring; Described steel pipe girder two ends are respectively equipped with two locating holes, described locating hole arranges along steel pipe girder length direction, in being equipped with, described steel pipe girder two ends are placed on main girder steel wherein, described main girder steel insertion end is provided with several fixing holes that coordinates locating hole, and steel pipe girder is connected with latch by bolt with main girder steel; Between steel pipe girder, be provided with connector between inferior girder steel, described operating desk is located on framework.
While adopting technique scheme, in main girder steel, be placed on steel pipe girder, steel pipe girder two ends are respectively equipped with two locating holes, and main girder steel insertion end is provided with several fixing holes that coordinates locating hole, and be connected with latch by bolt, so be arranged at the main girder steel at steel pipe girder two ends, can stretch; When steel platform is installed, the main girder steel at steel pipe girder two ends is stretched out, and be connected with latch by bolt, main girder steel is erected on the floor of elevator shaft both sides, and main girder steel one end is stretched in the reserved hole of shear wall; In the time of need to carrying lift steel platform, first with tower crane, at the suspension ring of steel pipe girder, apply pulling force, by the main girder steel income at steel pipe girder two ends, and fix by bolt and latch, then whole steel platform is upwards promoted, be mounted to the construction location of top.The utility model can promote, so set up operating platform without using a large amount of constructional materialss, and be erected on the floor of elevator shaft both sides by four main girder steels, and one end stretches in the reserved hole of shear wall, stressed even and simple in structure, avoided support body to set up the stressed unstable security incident causing of higher existence.
Further, described main girder steel insertion end is provided with three fixing holes, and two fixing holes of three fixing holes and main girder steel, just can meet the operation that main girder steel stretches out and takes in.
Further, described operating desk is to be positioned at the upper and lower two-layer gauze wire cloth of framework, and upper strata protective screening is used for preventing construction material, and lower floor's gauze wire cloth can play protective action.
Further, described operating desk is the steel plate being welded on framework, at steel plate, as operating desk, can place more construction material.
Further, the surrounding of described framework is provided with protective screening, and the construction article that can effectively avoid being positioned on operating desk drop, and causes security incident.
