Double up land assembly floor hanging mechanism for driving floor preceding rise type construction methods

摘要

PROBLEM TO BE SOLVED: To facilitate the level adjustment by supporting a lower fitting with a hoisting rod, which is suspended from an upper fitting, and supporting an upper part of the hoisting shaft with the lower fitting freely to be moved in the vertical direction, and hoisting a floor, which is assembled on the ground, with the hoisting shaft through a hoisting tool. ;SOLUTION: An upper fitting 7 is placed on a flange of a large beam 6 of a driving floor so as to ride over it in the cross direction. An upper part of two hoisting rods 8 are respectively fitted to the upper fitting 7 by a double nut 9 so as to be hoisted in parallel with each other. A lower fitting 10 is fitted to a lower part of the hoisting rods 8 by a double nut 11, and while a hoisting shaft 12 is fitted to an intermediate position of the hoisting rods 8 by a double nut 14 so as to pass through the lower fitting 10. A hoisting tool 15 is connected to a lower part of the hoisting shaft 12 by screwing. A hoisting part 20, which is provided in the top surface of the flange of a steel framed beam 19 of a floor assembled on the ground, is pinched by the hoisting tool 15, and a pin 21 is inserted for connection. Level adjustment of the height position of the floor, which is assembled on the ground, can be easily performed by turning the nut 14 in the normal direction or the reverse direction so as to move the hoisting shaft 12 in the vertical direction.;COPYRIGHT: (C)1997,JPO
