Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction, relates to high pier construction using a hydraulic climbing formwork, and specifically relates to a hydraulic climbing formwork wind-resistant reinforcement method. Background Art

[0002] Hydraulic climbing formwork is often used for the construction of high bridge piers. The hydraulic climbing formwork includes a formwork system, a climbing system and a protection system. The formwork system is fixed to the pier body through a climbing cone, and the climbing system and the protection system are fixed to the formwork through bolts and latches. The climbing system includes a climbing frame, a guide rail and a hydraulic system for lifting the formwork. The protection system is equivalent to a scaffolding, on which a construction platform and guardrails are set.

[0003] Typhoons are often encountered during the construction of coastal areas and offshore bridges. The climbing system and protection system of the hydraulic climbing formwork protrude from the outside of the pier and have weak wind resistance. To ensure construction safety, the climbing system and protection system are usually temporarily removed before the typhoon arrives and reinstalled after the typhoon. Both disassembly and installation take a lot of man-hours, and the risk of high-altitude construction is high. Summary of the invention

[0004] The purpose of the present invention is to provide a method for wind-resistant reinforcement of a hydraulic climbing formwork in order to solve the above-mentioned problem, so as to directly reinforce the climbing formwork in situ without dismantling the climbing frame, so as to improve construction efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] A method for wind-resistant reinforcement of a hydraulic climbing formwork, the hydraulic climbing formwork comprising a formwork system, a climbing system and a protection system, the formwork system being fixed to the pier body through pre-embedded climbing cones in the pier body, and the climbing system and the protection system being fixed to the formwork through bolts and latches, characterized in that the method comprises the following steps:

[0007] (1) Install the outer reinforcement chain: a layer of outer ring chain is bundled around the protective system of the climbing formwork at a certain height, and multiple outer vertical chains are connected at equal distances between the outer ring chains to form an outer chain network;

[0008] (2) Install the inner reinforcement chain: tie a layer of inner ring chain around the climbing formwork climbing system at a certain height, the interval height is the same as the interval height of the outer ring chain, and connect multiple inner vertical chains at equal distances between the inner ring chains to form an inner chain network;

[0009] (3) Multiple radial chains are connected equidistantly in the annular direction between the outer chain network, the inner chain network and the pre-embedded climbing cones of the pier body to form a three-dimensional climbing formwork reinforcement chain network.

[0010] The present invention adopts a chain combination system bundling scheme, which bundles the climbing formwork climbing system, the protection system and the constructed pier body into an integral structure, realizes the on-site wind-resistant reinforcement construction of the climbing formwork, can ensure the wind-resistant ability of the climbing formwork, effectively solves the problem of difficult wind resistance of the climbing formwork, and improves the construction efficiency and safety of the climbing formwork.
