Frame structure assembly type vibration reduction component and vibration reduction method
The invention belongs to the technical field of building vibration isolation, and discloses a frame structure assembly type vibration reduction component and a vibration reduction method, and the frame structure assembly type vibration reduction component is arranged at a beam-column joint gap position of a frame structure adjacent to a railway line. In the frame adjacent to the railway line, fabricated concrete building blocks are additionally arranged at the gap positions of beam-column joints, the component is fixed at the gap positions of the joints through expansion screws, cast-in-place and prefabrication can be performed in advance, and transmission of railway environment vibration to an upper floor can be effectively weakened due to increase of impedance after the component is additionally arranged; the vibration reduction component is made of concrete building blocks which are simple and common; and according to the action mechanism of the vibration reduction component, the proper floor is selected to arrange the vibration reduction component, and the railway environment vibration effect of the upper floor can be effectively reduced. According to actual requirements, another floor can be arranged below the floor needing further vibration reduction, so that the expected vibration reduction effect is achieved, and the additionally-installed floor is more flexible.
本发明属于建筑隔振技术领域，公开了一种框架结构可装配式减振构件及减振方法，框架结构可装配式减振构件设置于邻近铁路线的框架结构的梁柱节点空隙位置。本发明在邻近铁路线的框架中，在梁柱节点处的空隙位置加装可装配式混凝土砌块，该构件通过膨胀螺丝固定在节点的空隙位置，可以现场浇筑也可以提前预制，加装后由于阻抗的增加，可以有效减弱铁路环境振动向上部楼层的传递；减振构件的材料采用混凝土砌块，材料简单常见；根据减振构件的作用机理，选择合适的楼层设置减振构件，可以有效地降低上部楼层的铁路环境振动效应。本发明还可以根据实际要求，在需要进一步减振的楼层以下再布置一层，来达到预期减振效果，加装的楼层更加灵活。
