Air transportation device for large cement foam roof panels

Abstract

The invention relates to an air transporting apparatus for large-scale cement foamed roof boards. The apparatus comprises a pair or rails which can be welded and fixed on a roof truss, and a vehicle frame assembly which is arranged on the rails and can move along the rails. With roofs with large spans, large altitudes and space truss structures, a construction area can not be covered by sling-equipment. With the large-scale cement foamed roof board air transporting apparatus provided by the invention, the difficulty can be solved, a phenomenon of cross construction caused by ground direct lifting can be eliminated, construction labor intensity can be greatly reduced, construction time can be shortened, working efficiency can be improved, machinery operation rate can be substantially improved, labor cost and machinery cost can be saved, and engineering cost can be reduced.

Description

technical field [0001] The invention relates to a transportation device, in particular to a large-scale cement foam roof panel aerial transportation device. Background technique [0002] Foamed cement composite board is a high-tech building board with light weight, high strength, heat preservation, load-bearing, fire prevention, waterproof, decoration, environmental protection, energy saving, durability, heat insulation, sound insulation and earthquake resistance. A new type of building product that conforms to the concept of circular economy and low carbon. figure 1 It is a cross-sectional schematic diagram of the WB-shaped steel frame of the commercially available cement foam roof panel, figure 2 It is a schematic cross-section diagram of the commercially available cement foam roof panel DB type steel frame, in which the WB size of the grid roof panel is 3.0×3.0m, and the unit weight of each piece is 562.5kg; the DB size of the large roof panel is 1.5×6.0m, and the unit ...

AI Technical Summary

Problems solved by technology

[0003] However, since the board is a new type of material, it adopts a 4-point support fixing method, the width of the bottom surface of the steel frame is only 25-30 mm, and the upper support plate of the roof truss structure is only a round steel plate of Φ200 mm; the roof board is a rigid structure, which is affected by the deflection of the roof truss system. The impact is relatively large. If there is no controllable means, local reverse slope and water accumulation will eventually be formed on the roof; since the large-area installation is located in the grid area, the conventional direct hoisting method of the crane cannot be used, and only one-sided or fixed-point vertical transportation can be used. Upper board, roof horizontal transportation method, and the roof horizontal transportation span is large, the longest transportation distance, the horizontal transportation distance is 84m, and the vertical transportation distance is 200m, the operation is very difficult

At present, there is no perfect and reliable transportation equipment for the construction of large-scale cement foam roof panels for space structures, ultra-high altitudes, and long-span roofs, and there is no mature and reliable construction technology for reference. The roof works of the T1 and T2 terminals of Pudong Airport adopt a suspension cable traction structure and human-assisted transportation, which cannot meet the construction time and schedule requirements.

[0004] Therefore there are above-mentioned inconveniences and problems in the known conventional hoisting mechanical hoisting and manpower-assisted transportation mode
