Sliding positioning-based screw safety docking device and implementation method

Abstract

The invention discloses a sliding positioning-based screw safety docking device and implementation method, belonging to the technical field of bridge construction. Load-bearing rods are symmetricallyequivalently distributed on the both sides of a split screw which passes through the middle gap; the periphery of a nut is fully welded to a backing plate with a circular hole, the center of the nut is in line with the center of the circular hole in the backing plate, and the diameter of the circular hole in the backing plate is slightly larger than the inner diameter of the nut, to ensure the welding quality; one leg of limiting angle steel is welded on the thickness direction plane of the backing plate, the limiting angle steel fulfills the function of lateral limiting, and the limiting angle steel also serves as a neck allowing the load-bearing members to slide up and down; and steel slings are fixed on the backing plate, and the steel slings can be manually pulled to adjust the position of the connecting member composed of the limiting angle steel, the nut and the backing plate until the positioning requirements are met. The invention provides a new on-line construction method, which has obvious advantages such as reducing falling objects, simple and convenient operation, capability of speeding up construction and the like, and has high practicability when being compared with the conventional construction methods.

Description

technical field [0001] The invention relates to a screw safety docking device based on sliding positioning, which is suitable for the safety application technical field of railway bridges, highway bridges, urban viaducts and various large-scale continuous beam structure buildings spanning existing lines, and avoids the external construction process of the structure. A falling object belongs to the field of bridge building construction. Background technique [0002] Railway transportation has always occupied a pivotal position in our country and is an important channel for the circulation of people and materials. Therefore, the normal and safe operation of the line is very critical. The construction period of intercity railways, passenger dedicated lines and highways across existing lines will be longer, which will have a great impact on offline business lines, and the potential safety hazards will be prominent.

Problems solved by technology

The construction period of intercity railways, passenger dedicated lines and highways across existing lines will be longer, which will have a great impact on offline business lines, and the potential safety hazards will be prominent

[0003] At present, the possibility of falling objects is inevitable in high-altitude construction, which not only affects the normal operation of traffic, but also may easily cause major safety accidents and cause huge economic losses

For common construction methods, such as hanging basket construction, the components are complicated, there are many operations on the outside of the formwork, the process of formwork removal is complicated, and the possibility of tools and components falling is high.
