Abstract

The invention discloses a welded ball mesh frame locating device for a building house with the long span, and belongs to the field of roof construction of tall buildings. The welded ball mesh frame locating device comprises a plurality of ball holding units and a plurality of connecting mechanisms; the ball holding units comprise ball holding adjusting mechanisms, height adjusting mechanisms and support seats; the ball holding adjusting mechanisms comprise cylindrical shells, large cone gear discs, six holding jaws and three small cone gears; the large cone gear discs are driven to rotate in the cylindrical shells by the three small cone gears, and the six holding jaws are close to or away from the centers of the large cone gear discs simultaneously; the heights of the ball holding adjusting mechanisms are adjusted by the height adjusting mechanisms; the connecting mechanisms comprise two sleeve rings and connecting rods; the sleeve rings rotatably sleeve ring grooves formed in the circumferential surfaces of the cylindrical shells; and the two ends of the connecting rods are correspondingly hinged to the two sleeve rings. According to the welded ball mesh frame locating device forthe building house with the long span, quick locating welding can be conducted on the ground according to the irregular shape of the welded ball mesh frame of a tall building, and the working efficiency and the connecting precision are improved.

Description

Technical field [0001] The invention belongs to the field of roof construction of tall buildings, and specifically relates to a welding ball grid positioning device used for roofs of large-span buildings. Background technique [0002] Steel structure is a statically indeterminate space system composed of steel pipe, section steel or angle steel and other cross-section types of rods combined according to a certain geometric drawing. Steel grid structure began to appear in China in the 1960s, and now a large number of buildings in China have adopted steel grid structure. There are many types of joints in the steel grid, and the commonly used ones are welded ball joints and bolted ball joints. The welded ball joint is suitable for the connection of round steel pipes. The joint structure is simple, the force transmission is clear, and the overall rigidity is relatively large. However, it is more difficult to realize the grid frame when it is installed in place, and it often require...
