Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, the utility model discloses a scalable foldable elevartor shaft construction operation platform includes main platform 20 and the folding platform 30 that is located its horizontal both sides, and folding platform 30 is connected with folding platform 30 through hinge 12 that vertical interval set up. The main platform 20 is provided with telescopic support mechanisms at two longitudinal ends at intervals.
Referring to fig. 2, the main platform 20 is composed of a main platform frame and a steel mesh 13 covering and fixed on the main platform frame, the main platform frame is a rectangular frame composed of two rectangular pipe main beams 1 arranged at intervals transversely and two rectangular pipe secondary beams 3 arranged at intervals longitudinally, a plurality of middle angle steel secondary beams 5 are arranged between the two rectangular pipe secondary beams 3 at intervals longitudinally, and two ends of each rectangular pipe secondary beam 3 and each middle angle steel secondary beam 5 are welded with the rectangular pipe main beams 1. The telescopic supporting mechanism is a rectangular pipe inner sleeve main beam 2 inserted into the rectangular pipe main beam 1, positioning holes are formed in the rectangular pipe main beam 1 and the rectangular pipe inner sleeve main beam 2, and a positioning steel pipe 11 is vertically inserted into each positioning hole. The outer extending end of the main beam 2 in the rectangular pipe is sealed by a seal head steel plate 4. And round steel handles 10 welded with the inner side angle steel main beam 8 are arranged on the inner side angle steel main beam 8 at intervals for facilitating the stacking operation.
Referring to fig. 2, the folding platform 30 is composed of a folding platform frame and a steel mesh 13 covering and fixed on the folding platform frame, the folding platform frame is composed of an outer side angle steel main beam 7 and an inner side angle steel main beam 8 which are transversely arranged at intervals and a plurality of side angle steel secondary beams 6 which are longitudinally arranged at intervals, and two ends of each side angle steel secondary beam 6 are respectively welded with the outer side angle steel main beam 7 and the inner side angle steel main beam 8.
The main platform 20 and the unfolded folding platform 30 are matched in size, and a placing hole of a support beam (a main beam 2 is sleeved in a rectangular tube) is reserved on the shear wall according to the size of the operation platform.
