Abstract
The utility model provides a foundation structure for a tower crane in a construction site, belonging to the technical field of construction machinery. The foundation structure for the tower crane solves the problem that the safety and the progress of construction are influenced by the lower stability and firmness of the tower crane. The foundation structure for the tower crane comprises four bored grout piles which are arranged at four corners of a rectangle; the upper side of each bored grout pile is fixedly provided with a lattice type steel column; the cross sections of the lattice type steel columns are rectangular; the lattice type steel columns are formed by welding four pieces of angle steel arranged at the four corners of the rectangle by means of batten plates which are axially arranged at intervals; slant supports are connected among the four lattice type steel columns; steel channels are horizontally connected between the two adjacent lattice type steel columns which are positioned at both ends of the slant supports; cross type horizontal supports are arranged on the diagonals of the rectangle enclosed by the steel channels; the upper ends of the lattice type steel columns are connected with section steel platforms; and the upper surfaces of the section steel platforms are provided with tower foot assembly parts for the tower crane. The foundation structure is firmer in structure and is more stable in the operating process of the tower crane.
