Description
Technical Field
The utility model relates to the technical field of steel structures, in particular to a lifting frame without rod piece replacement.
Background
The lifting technology belongs to a common steel structure construction technology, the structure is positioned on the ground or assembled in a low altitude mode during construction, and the whole structure is lifted to a specified installation position through computer hydraulic control equipment. The lifting support is an essential link in the lifting construction process. Only when the lifting equipment is fixedly arranged on the upper part of the lifting support, the structure can be accurately lifted in place. The installation and disassembly simplicity degree of the lifting support directly influences the construction period of the lifting construction; the accuracy of the height of the lifting support directly influences whether the structure can be installed in place or not in the lifting process; the stability and safety in the lifting process are directly influenced by the arrangement of the lifting support and the firmness of the lifting support.
Therefore, each construction unit, construction administration unit, supervision unit, and the like pay attention to the type selection and erection of the lifting support. The conventional lifting support mainly adopts a four-limb lattice column form, although the form is strong in universality, a plurality of obvious problems also exist, and the conventional lifting support is specifically as follows:
1. the workload of installation and disassembly is large. Because the structure adopts four limbs truss type, the web member is many, and the welding volume is big, and manufacturing time is long, loaded down with trivial details when demolising.
2. Rod replacement is required. Before the promotion construction, the structure is assembled and will be taken out with the hoisting frame setting position overlap position member, need add the anchor strut temporarily around the primary structure simultaneously for guaranteeing structural strength. After the reinforcing rods are lifted in place, the reinforcing rods are dismantled, and the original designed rod pieces are installed. This has prolonged the promotion construction period, has destroyed original structural design simultaneously.
3. The eccentricity is stressed seriously. If the lifting point is a single lifting point, the upper part of the four-limb lifting support needs to be temporarily provided with a one-way cantilever frame for placing a lifter, and the four-limb lifting support is eccentric and seriously stressed during lifting (a typical single-lifting-point four-limb lattice lifting support is shown in a figure 1), and is easy to incline. Therefore, the four-limb lifting frame has low bearing redundancy, the section of the rod piece is inevitably increased to ensure the bearing capacity, and the material consumption is increased.
4. Can not be repeatedly used, and a specific design structure is needed for specific engineering.
