Problems solved by technology

[0004] 1. When the length of the anti-buckling support steel core is long, the steel core will form multiple bands of bending deformation. When the bending of multiple bands is leveled by applying a force perpendicular to the length direction of the steel core, the leveling accuracy is not high;
[0005] 2. After the leveled steel core is placed for a period of time, due to its own weight or the stress left by the leveling process, the plane deflection will gradually recover and increase;
[0006] 3. When assembling the steel core and the constraining sleeve, in order to reduce the deflection and deformation of the steel core in the constraining sleeve, it is necessary to design a positioning and deformation limiting device in the constraining sleeve, which not only increases the workload, but also due to space constraints, positioning and The limit is difficult to be accurate

Abstract

A buckling-restrained brace manufacturing device comprises a clamping mechanism, an adjusting and leveling mechanism, a tension mechanism, a control mechanism and a pressure sensor, wherein the clamping mechanism is used for clamping a steel core, the tension mechanism is used for applying axial tension to the steel core to realize secondary leveling, the control mechanism is used for controlling stretching action and tension strength of the tension mechanism by extracting information of the pressure sensor, and the adjusting and leveling mechanism is used for adjusting a restraint sleeve to be centered. A manufacturing method includes the steps: clamping the steel core penetrating into the restraint sleeve; applying axial tension to the steel core to realize secondary leveling; adjusting the steel core to be positioned at the center of the restraint sleeve; sealing end openings of the restraint sleeve; filling fillers into the restraint sleeve; and unloading, loosening a fixture and taking down a finished product. The buckling-restrained brace manufacturing device is simple in structure, scientific in design, convenient to mount, economical and practical. The manufacturing method is simple to operate, accurate in control, fine in secondary leveling effect and low in manufacturing cost, the steel core is high in planeness precision, and superior overall performance of a buckling-restrained brace is ensured.

Description

technical field [0001] The invention relates to a production device and method for buckling-resistant braces used in bridges and construction projects, in particular to a device for manufacturing high-precision buckling-resistant braces and a method for manufacturing buckling-resistant braces using the same. Background technique [0002] The anti-buckling brace used in bridges and construction projects includes a restraint sleeve and a steel core inside the restraint sleeve. During the manufacturing process, how to control the accuracy of deflection and deformation of the steel core in the restraint sleeve has a great impact on the overall performance of the buckle-resistant brace. , because there is no special anti-buckling support manufacturing device, the main process currently used is: firstly, the deformation and deflection of the steel core is leveled and straightened by applying a force perpendicular to the length direction of the steel core, and then penetrated into t...
