Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with specific embodiments.

[0048] A variable-section cantilever formwork suitable for rapid construction, including a formwork system, an operating platform, and a connection system.

[0049] The formwork system includes multiple formwork units, and each formwork unit includes panels, I-beams, channel steel, connecting claws, bolts, steel nails, and hooks. In this embodiment, the panel adopts a 21mm multi-layer board. The length direction of the wooden I-beam is set along the height direction of the panel, and multiple wooden I-beams are arranged at intervals along the width direction of the panel, and the wooden I-beam is fixed on the panel by steel nails; the length direction of the channel steel is along the width direction of the panel It is provided that at least two channel steels are arranged at intervals along the height direction of the panel, and the channel steels are detachably...

Abstract

The invention relates to a variable-section cantilever formwork suitable for rapid construction. The variable-section cantilever formwork comprises a formwork system, an operating platform and a connecting system. The formwork system comprises a plurality of formwork units, and each formwork unit comprises a panel, a wood I-shaped beam, channel steel, a connecting claw, a bolt, a steel nail and alifting hook. Each template unit is provided with an operation platform; the connecting system comprises a core belt, a core belt pin, a cable-stayed seat and a pull rod; the adjacent template units arranged on the same surface are connected through a core belt and a core belt pin; the two formwork units arranged at the corners are connected through pull rods and cable-stayed seats, and the cable-stayed seats and the formwork units are connected through core belts and core belt pins. The invention further relates to a construction method adopting the variable-section cantilever formwork. The method is suitable for industrialized and standardized production, high-altitude operation rapid construction and installation standardized operation, efficient bridge construction is achieved, and themethod belongs to the technical field of bridge construction structures.

Description

technical field [0001] The invention relates to the technical field of bridge construction structures, in particular to a variable-section cantilever formwork suitable for rapid construction, and also relates to a construction method using the variable-section cantilever formwork. Background technique [0002] Nowadays, in the field of high-altitude operations, hanging formwork construction is still used in small-scale special high-altitude operations because of its economy, such as some cable-stayed bridge construction projects. Because of the height of the main towers of cable-stayed bridges, they often play the role of landscape architecture in cities. Therefore, the main towers of many cable-stayed bridges are designed with variable cross-sections while ensuring structural strength to improve their ornamental value. Choose a variable-section cantilever formwork with good economy and rapid construction, and carry out various constructions with variable sections. Not only...
