Method for pouring high pier column through electric creeping formwork device

Abstract

The invention provides a method for pouring a high pier column through an electric creeping formwork device. By the adoption of the method for pouring the high pier column through the electric creeping formwork device, defects of the prior art are overcome, the high pier column can be poured rapidly, the overall structure is simple, construction is convenient, and the efficiency is high. According to the technical scheme, the method for pouring the high pier column through the electric creeping formwork device comprises the steps that a creeping formwork system, a part embedding system and a frame body system are prepared for later use; an electric chain-block self-creeping formwork is mounted; after concrete pouring is completed, steel bars are bound, a formwork is removed and moved backwards, a wall-attached hanging seat is mounted, climbing on a frame body is conducted, form boards are cleaned and coated with release agents, formwork assembling is conducted, the form boards are reinforced and aligned, an embedded sleeve of the hanging seat is mounted, concrete is poured, and the next cycle is conducted; and formwork assembling and disassembling are conducted. The method can be widely applied to the field of construction of high pier columns.

Description

technical field [0001] The invention discloses a method for pouring high pier columns by using an electric climbing formwork device, which belongs to the technical field of high pier column construction. Background technique [0002] With the rapid development of traffic and the improvement of bridge technology, modern bridges are gradually developing in the direction of large spans. Due to the structural needs and the constraints of the topography and landform of the bridge location, bridge piers with a height of more than 100 meters and hundreds of bridges are designed. Meter-high cable towers (used in cable-stayed bridges and suspension bridges) are no longer uncommon, which puts forward higher requirements for construction technology. Facing such a high hollow (or solid) thin-walled building, how to achieve high-quality, safe and efficient construction is a difficult problem in modern bridge construction. The traditional overturning construction method that has been use...

AI Technical Summary

Problems solved by technology

[0003] (1) The operating platform must be formed by floor-to-ceiling scaffolding or a climbing frame made separately. After the construction of pier columns reaches a certain height, it is extremely unsafe for personnel to operate. Similar safety accidents often occur in actual construction

[0004] (2) The loading and unloading of the formwork needs to be completed by lifting equipment. The lifting equipment has many lifting times and low efficiency. At the same time, the formwork installation error is large and the correction is difficult, which restricts the quality of pier column construction

[0005] (3) For every rising section of the pier column construction, it is necessary to manually connect the high scaffold or lift the climbing frame, which is low in operation efficiency and increases the safety risk

[0006] (4) The wind resistance is low, in order to ensure safety, the actual operation time will be greatly reduced

[0007] The Chinese patent with authorized publication number CN102535341A discloses a hydraulic climbing formwork construction process for a high pier, using a hydraulic electric climbing formwork device for lifting, which solves the above-mentioned problems. Inconvenient, the required accessories are complicated in structure, and the construction efficiency is low
