the two-step two-span connecting rods 7 are arranged between the inner well and other full-span scaffold 1 and the outer ring double-row ground-falling hand frame 2, a plurality of two-step two-span connecting rods 7 are uniformly arranged along the circumferential direction of the cylinder 8, and two ends of each two-step two-span connecting rod 7 are respectively connected with the inner well and other full-span scaffold 1 and the outer ring double-row ground-falling hand frame 2;
the stair units 9 are arranged between two adjacent layers of the cross-hall scaffold 1 such as an inner well, and the stair units 9 are Z-shaped stair structures;
and the connecting channel 10 is horizontally arranged between the inner well platform and the outer ring platform 11, and two ends of the connecting channel 10 are respectively connected with the inner well platform and the outer ring platform.
In the embodiment, a cylindrical structure internal full-hall floor scaffold is built in a desulfurization absorption tower, firstly, the span and the step distance are calculated according to the tower diameter of the desulfurization absorption tower, and then the position of a vertical rod is determined by scribing and positioning. The inner well and the like span the hall scaffold 1 and vertically set up the central position in the desulfurizing absorption tower along the direction of height of the desulfurizing absorption tower, the outer ring double-row falling foot hand rest 2 is close to the inner wall of the desulfurizing absorption tower and is built, the inner well and the like span the hall scaffold 1, and the outer ring double-row falling foot hand rest 2 is also vertically set up along the high-speed direction of the desulfurizing absorption tower. The outer ring double-row drop leg hand frame 2 is arranged into two rows of inner rings and outer rings because the outer ring platform 11 is formed by paving a second steel plate on the outer ring double-row drop leg hand frame 2. The inner well and the like span-full-hall scaffold 1 and the outer ring double-row floor scaffold 2 are respectively erected in a layered structure layer by layer along the height direction of the desulfurization absorption tower, and the inner well and the like span-full-hall scaffold 1 and the outer ring double-row floor scaffold 2 have the same layer number and are correspondingly arranged in a matching manner. A plurality of two-step two-span connecting rods 7 are arranged between each inner well and the like span hall scaffold 1 and the outer ring double-row lower foot hand frame 2, and each two-step two-span connecting rod 7 connects the inner well and the like span hall scaffold 1 and the outer ring double-row lower foot hand frame 2 into a whole, so that the whole scaffold is more stable. The stairway units 9 are arranged between adjacent layers of the inner well and other cross-filling hall scaffold 1, and workers can go up and down the whole scaffold through the stairway units 9 without climbing the scaffold, so that the safety risk of the workers is greatly reduced. The inner well platform which is 1.5mx1.5m and is arranged on the inner well and other cross-hall scaffold 1 is used for buffering the up-and-down congestion and rest of personnel, and the outer ring double-row falling foot hand frame 2 is provided with the outer ring platform 11 which is used for the personnel to stand when overhauling the desulfurization absorption tower. A connecting channel 10 is arranged between the inner well platform and the outer ring platform 11, so that workers can conveniently reach the working surfaces of all floors through the stair units 9.
Further, the transverse and longitudinal spans of the well lattice structure are all 1.5m.
Further, the interval between adjacent layers of the cross-hall scaffold 1 of the inner well and the like is 1.8m.
Further, the double-row annular structure comprises an outer annular longitudinal rod 3, an outer annular transverse rod 5 and a short longitudinal compensation rod 4, the outer annular longitudinal rod 3 and the short longitudinal compensation rod 4 are arranged at intervals and are sequentially connected end to form an inner ring and an outer ring of the double-row annular structure respectively, the outer annular transverse rod 5 spans the inner ring and the outer ring, and two ends of the outer annular transverse rod 5 are connected with the joint of the outer annular longitudinal rod 3 and the short longitudinal compensation rod 4. Because the outer ring double-row falling foot hand rest 2 is of an annular structure, arc transition cannot be formed only by using the outer ring longitudinal rods 3 with the same length, and therefore, a short longitudinal compensation rod 4 is additionally arranged between two adjacent outer ring longitudinal rods 3 to form arc transition, and finally, an annular shape is formed, the length of the outer ring longitudinal rods 3 in the embodiment is 1.5m, and the length of the short longitudinal compensation rod 4 is determined by a specific excessive arc to form a smooth arc shape. The outer ring cross rod 5 connects the inner ring and the outer ring with two double rows of circular rings, so that the two rows of circular rings form a whole on one hand, and the outer ring double rows of lower foot hand frame 2 can form a frame structure on the other hand, and the outer ring platform 11 can be conveniently built. The length of the outer ring rail 5 in this embodiment is 1m. In specific working conditions, the distance between two rings of the outer ring double-row landing scaffold 2 is required.
Further, the outer ring longitudinal bars 3, the outer ring transverse bars 5 and the short longitudinal compensation bars 4 are all provided with a plurality of.
Further, the stairway unit 9 includes a steel frame plate, a scaffold tube and a fastener, the fastener connects the scaffold tube to form a Z-shaped frame with a 45-degree inclination angle, and the steel frame plate is laid on the Z-shaped frame. The steel frame plate in the embodiment is selected from steel frame plates with the specification of 600mm-250mm-50 mm.
Further, the second steel plate is an isosceles trapezoid with the width of 25cm and the thickness of 5 cm. Because the outer ring double-row falling leg hand frame 2 is of an annular structure, a standard steel frame plate with the diameter of 3000mm-250mm-50mm cannot be used, and potential safety hazards exist in gaps between adjacent steel plates due to the adoption of standard steel plates. The second steel plate in this embodiment is selected to be 25cm wide isosceles trapezoid, 5cm thick, and four second steel plates form a unit when laying, so alright make second steel plate zero clearance connect, can be safer when staff walks or the operation.
