Problems solved by technology
Therefore, the hoisting of roof eaves steel structure trusses will be widely involved in construction applications. For non-single building complexes, there are often construction blind spots, that is, the construction site in the middle of the adjacent building is narrow, and large tower cranes or truck cranes cannot be used. For overall hoisting, when it is not possible to use large-scale mechanical hoisting equipment to install large-scale cornice steel frames, the keel frames are usually hoisted separately, and then workers carry out high-level bulk installation. A certain pressure is caused, which affects the assembly quality; on the one hand, positioning and setting out at a high position reduces the accuracy, which also affects the assembly quality; moreover, because of the inconvenience of high-altitude operations, it seriously affects the construction efficiency, prolongs the construction period, and increases the construction cost.
To sum up, traditional construction methods have a great impact on progress, quality and cost

The invention discloses a sliding hoisting device and method for a large-scale steel truss in a narrow space, which specifically adopts a construction method of setting up a temporary installation platform, pre-assembling, and overall sliding hoisting; the pre-assembly of the reverse eaves keel is performed through the temporary installation platform , using the combined system of lifting device and lifting pulley, multi-lifting point binding is carried out on the keel of the reverse eaves, the steel cable track is used as the sliding track, the lifting pulley is used as the lifting point and the traveling tool, and the translation pulley is used as the direction control to complete the construction area Full-coverage multi-point stable control and the overall lifting and sliding of the anti-eave keel in the up-down, front-back and left-right directions; after reaching the installation surface, use the sliding device to fine-tune the position to complete the splicing with the main structure. The invention fully reduces the number of construction personnel and the application of large-scale machinery, shortens the construction period, improves construction efficiency, and brings good economic benefits.
Description
technical field [0001] The invention relates to the technical field of high-altitude steel structure installation, in particular to a sliding hoisting device and method for a large steel truss in a narrow space. Background technique [0002] At present, prefabricated steel structures and metal roofs are used for most large-scale complex buildings such as large-scale convention and exhibition centers and cultural venues. Therefore, the hoisting of roof eaves steel structure trusses will be widely involved in construction applications. For non-single building complexes, there are often construction blind spots, that is, the construction site in the middle of the adjacent building is narrow, and large tower cranes or truck cranes cannot be used. For overall hoisting, when it is not possible to use large-scale mechanical hoisting equipment to install large-scale cornice steel frames, the keel frames are usually hoisted separately, and then workers carry out high-level bulk insta...
