Abstract

The invention discloses a bolt limiting device of a fabricated tower crane foundation, and belongs to the technical field of the related technology of construction field equipment maintenance and construction safety. The bolt limiting device is used for limiting the position of a fastened bolt. The bolt comprises a nut and a cap. The bolt limiting device comprises a nut limiting plate, a cap limiting plate and a jacking part. The nut limiting plate is configured to be matched with the size of a relatively-closed beam grillage of section steel, a through nut hole is formed in the position, corresponding to the bolt, of the nut limiting plate, and the nut hole is matched with the nut. A through cap hole is formed in the position, corresponding to the bolt, of the cap limiting plate, and thecap hole is matched with the cap. The jacking part is fixed to the position, provided with the bolt, of the fabricated tower crane foundation and is used for bearing the cap limiting plate. By means of the bolt limiting device, bolt loosening can be limited to the largest degree, the safety of a tower crane system is greatly improved, the requirement of safe construction of construction fields ismet, and the advantage of saving manpower and material resources is achieved.

Description

technical field [0001] The invention relates to a bolt limiting device for an assembled tower crane foundation, and belongs to the related technical field of equipment maintenance and construction safety at the construction site. Background technique [0002] In building construction, tower cranes are widely used to solve the problem of vertical transportation during construction. At present, tower cranes are installed on the basis of combined or fabricated steel structure tower cranes. These steel structure tower crane foundations are usually composed of multiple H-shaped steels in a single-layer or multi-layer combination. [0003] Single-story steel tower crane foundations are usually fully welded together and then fixed to steel lattice columns. In the multi-layer combined or assembled steel tower crane foundation, the different layers of steel are connected by bolts, and then fixed on the steel lattice column by bolts, and then the steel lattice column is inserted int...
