Novel assembly type buckling-restrained device with inner groove
The invention discloses a novel buckling-restrained device with an inner groove. The section of the buckling-restrained device is not limited to be round or square. The anti-buckling steel sleeve comprises a component, an inner groove type steel sleeve, a gasket and a bolt, various components such as dog-bone-shaped components and bamboo-joint-shaped components are connected through the bolt after the components are wrapped and clamped by the inner groove type steel sleeve through a protrusion in the center of a weakening section, and the anti-buckling steel sleeve is formed; in a test, a test machine is directly connected with the component, and the novel buckling-restrained device only provides lateral restraint, provides proper rigidity for the component, effectively prevents the component from buckling, reduces the risk of buckling damage, and reduces the error of a tension and compression test of the component; the buckling-restrained steel sleeve is formed by assembling all bolts and is convenient to mount and dismount, and a novel assembly type buckling-restrained device is provided for exploring tension and compression hysteresis behaviors of different components. In engineering, damage of the member after an earthquake can be observed only by replacing the member, and the buckling-restrained device can be repeatedly used.
本发明公开了一种具有内凹槽型的新型防屈曲装置，该防屈曲装置截面不拘泥为圆形、方形。本发明包括构件、内凹槽型钢套、垫圈和螺栓，无论狗骨型、竹节型等多种构件，通过削弱段中心处凸起，内凹槽型钢套包裹并卡住构件后用螺栓连接，形成防屈曲钢套；试验中，试验机器直接与构件连接，这种新型防屈曲装置仅提供侧向约束，为构件提供合适刚度，有效防止构件发生屈曲，降低屈曲破坏风险，减少构件拉压试验误差；该防屈曲钢套全螺栓装配而成，便于安装和拆卸，为探究不同构件的拉压滞回行为提供一种新型装配式防屈曲装置。工程中，仅需更换构件，可观察震后构件的损伤，该防屈曲装置可重复使用。
