Technical Field
The utility model relates to the technical field of building construction, in particular to a tower crane standard knot convenient to disassemble and assemble.
Background
The tower crane is a rotary crane arranged at the upper part of the high-rise tower body. The tower crane has large operation space, is mainly used for vertical and horizontal conveying of materials in house building construction and installation of building components, and consists of a metal structure, a working mechanism and an electrical system.
The standard section of the tower crane is an important component of the tower crane and is also an important component with stable main structure of the tower crane, the tower crane not only bears the load of the dead weight of the upper structure of the tower body and wind load, but also supports the normal operation of the structural members and the mechanism of the upper structure of the tower body, and along with the continuous rising of a building, the height is continuously increased by overlapping the standard section so as to adapt to the vertical transportation of the rising of the building, and the standard section are fastened and connected through bolts.
A qualified standard section can not only improve the stability of the tower crane cranes, but also obviously improve the safety performance and the working efficiency of the tower crane, and even can achieve the effect of twice the result with half the effort.
At present, the standard section of the tower crane is assembled by producing the integrated standard section in a factory, then transporting the standard section to a construction site, and finally installing the standard section on the tower crane by using hoisting equipment, wherein the standard section is connected with the standard section by using bolts. However, during transportation, it is found that the integrated standard knot occupies more space during transportation, so that the parts loaded by the primary truck are limited, and the corresponding transportation cost is increased. Therefore, the standard section can be split into a plurality of connecting rods and then transported to a construction site, and the standard section is assembled and welded together at the construction site.
The connecting piece and the welding of connecting piece constitute the standard festival, when dismantling a section of standard festival, can only wholly transport a section of standard festival, perhaps cut off standard festival connecting rod, unify and transport, and this kind of transportation mode, corresponding transportation cost also can correspondingly increase, and the efficiency of transportation is not very high yet simultaneously.
