Steel structures are increasingly used in building construction, especially factory buildings, and the steel structure construction forms are increasingly complex. The current conventional steel structure hoisting mode mainly adopts a tower crane or an automobile crane, and forward hoisting is carried out after strapping by a sling, and the construction process is required to be gradually hoisted from bottom to top. Taking an automobile crane as an example, when the steel member is hoisted by adopting the automobile crane, the hanging strip sagging and the safe operation space requirement are considered, the hoisting part needs enough upper space, the front end of the large arm is required to be far higher than the installation surface of the steel member, and the steel structure roof can be stretched generally, for example, the steel structure roof can not be hoisted in time, and the integral construction of the steel structure is restricted. When the steel frame structure factory building roofing design, have some horizontal direction's secondary structure component generally, like the circular pull rod of steel construction, the distribution is more extensive, quantity is more, and hoist and mount spends time for a long time, and because arrange closely, often can appear the problem that the preceding step component hoist and mount is accomplished, but follow-up component is difficult to hoist and mount, the construction degree of difficulty is big, and has restricted the progress of steel construction to a certain extent.
The existing steel structure hoisting mode can meet the hoisting requirements of conventional steel structure components, but in a steel frame structure factory building, the conditions that the construction period is short and the roof is required to be closed as soon as possible often exist, and in the conditions, besides the fact that the field hoisting is quickened by adding machinery and the like, the installation of secondary structure components in the steel structure can be considered to be postponed, the roof enclosing system is constructed in advance, and the installation of the secondary structure components at the lower part is reversely carried out after the roof enclosing system at the corresponding part is completed. However, since the hoisting work space is limited and the level of the secondary structural member (support) is difficult to control by the strapping, the holes at both ends of the secondary structural member (support) and the screw holes of the ear plates are difficult to align at the same time, the installation speed is slow, and the overall progress is affected. Based on the above conditions, taking a conventional steel structure supporting tie bar as an example, the anti-lifting device for the steel member is provided, and the purpose of post-mounting of the horizontal secondary member of the steel structure is achieved by locally refitting and applying the anti-lifting device to the end part of the lifting arm of the automobile crane.
