Embodiment Construction

[0013] The present invention is further illustrated below by specific examples.

[0014] A temporary reinforcement method for replacing equipment anchors in tension lifting construction, including tooling lugs (2), first steel plates (3), dowel bars (5), extended casing connectors (7), second Steel plate (9) and stop nut (10); when the cable structure (1) is in the process of tensioning and lifting, when the anchorage of the lifting equipment breaks down and needs to be replaced or when the lifting steel strand is broken, the following steps should be implemented:

[0015] Step 1. Determine the lug plate (2), the first steel plate (3), the dowel bar (5), the extension sleeve connector (7), and the second steel plate (9) according to the size of the anchorage and steel strand and the specification and size of the stop nut (10), and the model of the hydraulic jack (8);

[0016] Step 2. Place two first thick steel plates (3) around the oblique cable tensioning tool lugs (2) arou...

Abstract

The invention relates to a temporary reinforcing method for replacement of an equipment anchorage device in tensioning and lifting construction. The temporary reinforcing method comprises temporary reinforcing assemblies and is characterized in that in the tensioning and lifting construction process of a cable structure (1), when the lifting equipment anchorage device breaks down and needs to be replaced or a lifting steel strand outgoing line is broken, the method comprises the following steps of (1) determining the model of the temporary reinforcing assemblies according to the size of the anchorage device and the size of the steel strand; (2) arranging the temporary reinforcing assemblies on the periphery of the cable structure (1); and (3) unloading the load of a lifting mechanism step by step in a synchronous graded loading mode by four dowel bars (5) after the step (2) is implemented. The method provided by the invention is applied to a load transfer device used for hydraulic tensioning and lifting equipment ahchorage device or steel strand replacement when the cable head of an inclined cable is close to an anchoring point, the load on the tensioning and lifting mechanism with problems is safely and reliably transferred to a temporary reinforcing device, so that equipment replacement and load transfer are safely and smoothly completed.

Description

technical field [0001] The invention relates to the technical field of cable structure engineering tension lifting construction, in particular to a temporary reinforcement method for replacing equipment anchors in tension lifting construction. Background technique [0002] Usually, during the construction process of cable net tensioning and lifting, if the anchorage of the lifting equipment breaks down and cannot be repaired, the existing technology cannot solve this problem well, and the cable body can only be unanchored and placed on the tire frame to replace the anchor. The re-tensioning of the tool not only affects the construction efficiency but also affects the overall structural safety. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and propose a reinforcement method with simple structure, large bearing capacity and good stability, which can effectively solve the problem of difficult replacement of ...
