Abstract
The invention particularly relates to a temporary reinforcing method for replacing an anchorage device in tensioning and lifting construction, which comprises a temporary reinforcing component and is characterized in that: when the cable structure (1) is in a tensioning and lifting construction process, the lifting equipment anchorage device fails and needs to be replaced or the lifting steel strand is outgoing and broken, the following steps are implemented: step 1, determining the model of a temporary reinforcing component according to the sizes of an anchorage device and a steel strand; step 2, arranging temporary reinforcing components on the periphery of the cable structure (1); and 3, after the step 2 is implemented, the four dowel bars (5) unload the load of the lifting mechanism step by step in a synchronous step loading mode. The load conversion device for replacing the anchorage device (or the steel strand) of the hydraulic tensioning and lifting equipment when the distance between the inclined cable head and the anchoring joint is close converts the load on the tensioning and lifting mechanism with problems to the temporary reinforcing device safely and reliably, and ensures the safe and smooth completion of equipment replacement and load conversion.
Description
Technical Field
The invention relates to the technical field of tensioning and lifting construction of cable structure engineering, in particular to a temporary reinforcing method for replacing an anchorage device in tensioning and lifting construction.
Background
Usually, in the cable net stretch-draw lifting work progress, if lifting means ground tackle when breaking down unable maintenance, this problem of unable fine solution of prior art can only move back the anchor with the cable body and put on the bed-jig, changes ground tackle and stretch-draw again, not only influences the efficiency of construction but also influences overall structure safety.
Disclosure of Invention
The invention aims to overcome the defects and provides a reinforcing method which is simple in structure, large in bearing capacity and good in stability and can effectively solve the problem that the anchor of the lifting equipment is difficult to replace.
In order to achieve the above object, the present invention is realized by:
a temporary reinforcing method for replacing an anchorage device in tensioning and lifting construction comprises a tooling lug plate (2), a first steel plate (3), a dowel bar (5), a lengthened sleeve connecting piece (7), a second steel plate (9) and a spigot nut (10); when the cable structure (1) is in a tensioning and lifting construction process, the lifting equipment anchorage device fails and needs to be replaced or the lifting steel strand is outgoing and broken, the following steps are implemented:
step 1, determining the specifications and sizes of an ear installing plate (2), a first steel plate (3), a dowel bar (5), a lengthened sleeve connecting piece (7), a second steel plate (9) and a spigot nut (10) and the model of a hydraulic jack (8) according to the sizes of an anchorage device and a steel strand;
and 3, after the step 2 is finished, the load of the lifting mechanism is unloaded step by the four dowel bars (5) in a synchronous step loading mode, and when the load of the lifting mechanism is not large, the steel strand (11) is cut off, and the anchorage device of the tensioning lifting mechanism or the steel strand for lifting is replaced.
The load conversion device for replacing the anchorage device (or the steel strand) of the hydraulic tensioning and lifting equipment when the distance between the inclined cable head and the anchoring joint is close converts the load on the tensioning and lifting mechanism with problems to the temporary reinforcing device safely and reliably, and ensures the safe and smooth completion of equipment replacement and load conversion.
