Damping beam structure based on rubber concrete damping layer
The invention discloses a damping beam structure based on a rubber concrete damping layer. The damping beam structure comprises a concrete base beam, the concrete base beam, a rubber concrete damping beam and a concrete constraint beam are sequentially stacked and fixed from bottom to top to form a constraint damping beam, longitudinal bars extending in the length direction of the concrete base beam are arranged in the concrete base beam, longitudinal bars extending in the length direction of the concrete constraint beam are arranged in the concrete constraint beam, the upper portions of stirrups wrap the longitudinal bars in the concrete constraint beam, the middle portions of the stirrups penetrate through the rubber concrete damping beam, and the lower portions of the stirrups wrap the longitudinal bars in the concrete base beam. Mechanical energy is converted into heat energy through deformation of the rubber concrete damping beam to be dissipated, and therefore the damping effect is achieved. Energy can be effectively absorbed, possible earthquake damage of the beam structure is avoided, and therefore operation safety of constructional engineering is guaranteed.
本发明公开了一种基于橡胶混凝土阻尼层的减震梁结构，包括混凝土基梁，混凝土基梁、橡胶混凝土阻尼梁和混凝土约束梁从下至上依次叠放固定构成约束阻尼梁，混凝土基梁内设置有沿混凝土基梁长度方向延伸的纵筋，混凝土约束梁内设置有沿混凝土约束梁长度方向延伸的纵筋，箍筋上部包裹混凝土约束梁内的纵筋，箍筋中部贯穿橡胶混凝土阻尼梁，箍筋下部包裹混凝土基梁内的纵筋。本发明利用橡胶混凝土阻尼梁通过形变将机械能转变为热能耗散出去，从而达到减震的效果。可以有效吸收能量，避免梁结构出现可能的震害，从而保证建筑工程的运营安全。
