Abstract

This utility model discloses a cantilever construction formwork for continuous beams with varying beam widths. A main beam micro-adjustment rotation mechanism and a main beam translation slide are installed at the columns on both sides, between the main beam and the central crossbeam, and between the central crossbeam and the columns, allowing the formwork to move in a figure-eight pattern. A movable system with a movable upper front crossbeam sleeve allows the formwork to be moved and locked. The upper front crossbeam adjustment cylinder guides the formwork to adapt to the varying cross-section box girder, solving the problems of traditional formwork not being suitable for varying cross-section box girders and formwork only being able to move in parallel straight lines. Furthermore, the formwork lateral movement device has a simple, robust, and stable structure, is easy to move forward and disassemble, and has strong reusability. The formwork lateral movement device also aims to shorten the construction period, ensure safety and efficiency, save energy and protect the environment, and reduce costs.

Description

Technical Field

[0001] This utility model relates to the field of hanging basket construction technology, and in particular to a cantilever hanging basket for continuous beams with varying beam width. Background Technology

[0002] The demand for bridge construction is driven by the increasing development of transportation infrastructure, leading to a surge in the construction of long-span bridges. In the construction of prestressed concrete continuous rigid frame bridges and continuous beam bridges, the cross-sectional shape of the beams often changes due to factors such as stress characteristics. Traditional formwork systems have limitations when constructing beams with variable cross-sections. Traditional formwork construction only allows for straight-line movement, suitable for casting box girders with uniform cross-sections but not for those with variable cross-sections. Variable cross-section box girders require frequent adjustments to the formwork's position and shape to accommodate the increased width. The formwork must withstand various loads during construction, exhibiting minimal deformation under stress while minimizing its own weight and facilitating movement and adjustment. Ordinary variable cross-section formwork uses multiple hydraulic cylinders for lateral movement, which is inconvenient for movement and adjustment, and the junctions of the main beams are prone to deformation, preventing overall lateral movement.

[0003] Therefore, it is necessary to develop a cantilever construction formwork for continuous beams with varying beam widths to solve the above problems. Utility Model Content
