Abstract

The invention discloses a tower crane foundation structure for transmitting force to existing columns and a construction method thereof, which comprises a pair of tower crane foundation frames, an underground structure roof, connecting secondary trusses, secondary truss connecting ear plates, secondary truss connecting plates, and oblique inter-column trusses. Bracing and diagonal bracing connecting plates; the foundation frame of the tower crane is set above the roof of the underground structure, and a connecting secondary truss is arranged between the foundation frames of a pair of tower cranes. The inner side of the foundation frame is connected; between the lower end surface of the connecting secondary truss and the bottom of the foundation frame of the tower crane, inter-column diagonal braces are arranged, and a pair of inter-column diagonal braces are arranged symmetrically on both sides of the vertical central axis of the connecting secondary truss; the present invention utilizes both There are columns to convert the force of the tower crane foundation, effectively changing its mechanical transmission path, and directly acting the reaction force of the tower crane foundation on the existing columns of the original underground structure; it solves the problem that the back support at the bottom of the garage affects the passage of vehicles.

Description

technical field [0001] The invention relates to the technical field of tower crane foundation structures, in particular to a tower crane foundation structure that transmits force to an existing column and a construction method thereof. Background technique [0002] At present, the common construction method of tower crane foundation is based on cast-in-place concrete, and there are also prefabricated assembled foundations. However, the volume of poured concrete foundations is generally large, and the construction also needs to go through tying steel bars, supporting formwork, pre-buried bolts and pouring concrete. The construction period of the cast-in-place tower crane foundation is long. After the construction is completed, the tower crane foundation cannot be reused. After the tower crane is dismantled, the concrete foundation needs to be demolished by blasting or mechanical crushing. Inconvenient to transport and install. It is not conducive to the continuous developmen...
