Problems solved by technology

However, in each construction cycle of the hydraulic climbing formwork, the pre-embedding of the anchor, the installation of the hanging seat, and the conversion of the fulcrum after the bracket climbs into place require high precision in order to ensure smooth climbing and reliability of the fulcrum, so the construction progress is not high.

Embodiment Construction

[0033] Such as Figure 1 to Figure 7 Shown is the high pier hydraulic jacking integrated steel frame platform turning form construction system of the present invention, which includes: hydraulic jacking system, steel frame platform system, formwork and formwork lifting system.

[0034] The hydraulic jacking system includes a support rod 3, a lifting frame 4, a hydraulic jack 2, a hydraulic solenoid valve, a hydraulic pump, and a hydraulic console. The support rod 3 is fixed on the ground foundation, and the hydraulic through-hole jack 2 is clamped on the support rod and climbs along the support rod. The hydraulic through-hole jack, the hydraulic solenoid valve and the hydraulic pump are connected to form a hydraulic working circuit through the hydraulic oil pipe, and the climbing height of the hydraulic through-hole jack is controlled by the hydraulic console. The lifting frame includes a plurality of outer vertical rods and a plurality of lifting frame beams passing through ...

Abstract

The invention provides a high-pier hydraulic jacking integral type steel frame platform turnover construction system and a construction method. The construction system comprises a hydraulic jacking system, a steel frame platform system, a formwork and a formwork lifting system. The hydraulic jacking system comprises a supporting rod, a lifting frame, a hydraulic center hole jack and the like. Thehydraulic center hole jack is clamped on the supporting rod and climbs along the supporting rod. The steel frame platform system, the lifting frame and the hydraulic center hole jack are connected into a whole and ascend and descend synchronously. A plurality of sets of detachably connected supporting rods are arranged between the steel frame platform system and the formwork, when the supporting rods are locked and connected, the steel frame platform system and the formwork are synchronously lifted by the hydraulic center hole jack, when connection of the supporting rods is released, positionlocking of the steel frame platform system and the formwork is released, and lifting of the formwork is controlled by an electric hoist. The steel frame platform system and the formwork are lifted step by step, safety is high, construction efficiency is high, and the system is quite suitable for high pier construction.

Description

technical field [0001] The invention relates to the technical field of bridge pier construction, in particular to a formwork lifting system used in bridge pier construction. Background technique [0002] The construction of high bridge piers has the characteristics of high construction difficulty and high safety risk. The existing construction techniques commonly used in the construction of high bridge piers include methods such as tower crane overturning formwork, hydraulic sliding formwork and hydraulic climbing formwork. The concrete joints of the tower crane overturning construction method are smooth, the grouting effect is good, and the appearance quality of the concrete is guaranteed. However, when the formwork is disassembled and turned up, it is difficult for the operators to gain a foothold, and the construction conditions are difficult, resulting in a low number of work. The construction condition of the hydraulic slip form is better than that of the tower crane,...
