The invention discloses an ultra-long truss type tower crane attachment structure with a support. The ultra-long truss type tower crane attachment structure comprises a truss type attaching rod and anattaching frame, wherein the attaching frame is installed on a tower crane standard knot, one end of the attaching rod is connected with the attaching frame, and the other end of the attaching rod isconnected with a wall body. The ultra-long truss type tower crane attachment structure is characterized in that the attaching rod is of a three-section type structure, a front variable cross-sectiontruss, a rear variable cross-section truss and a middle rectangular cross-section truss connecting the front variable cross-section truss and the rear variable cross-section truss are arranged, the front variable cross-section truss is gradually enlarged from the front to the rear, and the rear variable cross-section truss is gradually enlarged from the rear to the front. According to the ultra-long truss type tower crane attachment structure, the self weight of a whole attaching system is reduced, the stability of the attaching system is improved, and meanwhile, a material and cost of the attaching system are saved as well.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a superlong truss type tower crane attachment structure with supports. Background technique [0002] When the traditional tower crane is used, the installation position only needs to consider the general parameters such as lifting weight, coverage, installation height, installation and disassembly conditions, etc. For the installation of the tower crane attachment frame, the attachment distance is the length from the center of the tower crane standard section to the attachment point, which is basically based on production The manufacturer's standard accessories are mainly used, and they can be adjusted within the range of 4 meters to 4.5 meters. In recent years, with the changes in the design of public buildings and civil buildings and the improvement of the design of industrial building functions, tower cranes not only need to consider the above content...
