SU898009A1 - Movable scaffold for servicing arch-shaped structures - Google Patents

Description

The invention relates to slide platforms for the production of sprayed toning on a pneumatic panel, preferably an arched form.

Known scaffolding for servicing dome-shaped structures, containing a cargo cabin, movably mounted on a farm, made in the form of a semi-arch with a rotary support in the upper part and movable around the structure with a wheel support in the lower part 1.

The disadvantage of these scaffoldings is that with the help of scaffolding of such a construction, it is impossible to maintain the structures of the arched form and ensure effective maintenance of sprinkling works.

Closest to the proposed invention are mobile scaffolding for servicing structures of arched shape, made in the form of a truss, carrying a mobile cabin and resting on the undercarriage and

consisting of upper and lower tips 2.

The disadvantage of these scaffoldings is that they cannot be used to maintain arched structures and cannot provide effective sprinkling work due to the fact that the cab suspension to the carriage does not allow it to be moved precisely along the contour of the erected structure. with a nozzle for sprayed concrete, as well as the inconvenience of handling sprayed concrete from the cabin inside the truss.

The aim of the invention is to increase the efficiency of conducting the sprinkling of concrete on the pneumatic deck, increasing labor productivity and ease of maintenance.

Operators who perform splashing work m, still in cab 12. The system for hanging cab 12 and performing the lower landing 2, in a configuration different from the upper landing 1, allow the cabin to remain parallel to itself when moving around the truss, which provides ease of operation, while the nozzle is perpendicular The surface of the structure being built, which creates conditions for efficient work, the quality of sprayed concrete on the pneumatic deck and the increase in labor productivity. The operation of mobile submt | oste is as follows. The process of spraying concrete onto a pneumatic deck is carried out, for example, by strips located across the structure axis. To apply the strip, the operators located in the cabs 12 turn on the pin drive 6, and the cabs 12 move upwards along the truss-shaped truss. Operators at this time controlled by nozzles 13, ensuring the efficiency, quality and uniform distribution of concrete over the surface of the pneumatic panel in the area of sprayed concrete. After the strip has been sprayed to the top of the pneumatic form, the operator switches on the drives of the undercarriage H, and the scaffolds move along the structure axis for the next nest (strip). The process of applying concrete in the zone of a new strip is carried out with due regard for ensuring the solidity of the seam by partially overlapping the areas of splashing of adjacent lanes when the cabs move from top to bottom. In the lowest position of the cabs, the drive mechanism is turned on, and the scaffolds are moved along the structure to the next setting of the sprayed concrete. Further, the cycle is repeated in the sequence indicated. The use of this invention allows to increase the efficiency of work on the spraying of concrete on the pneumatic partition, labor productivity and improve ease of operation. Claims 1.
