Damping anti-collision wind-resistant limiting device, suspension bridge steel truss girder and suspension bridge
The invention discloses a damping anti-collision wind-resistant limiting device, a suspension bridge steel truss girder and a suspension bridge, and relates to the technical field of suspension bridge damping limiting. The damping constraint device comprises a connecting piece, a rigidity element and a damping element; the number of the connecting pieces is two, and the connecting pieces are parallel to each other and used for connecting two adjacent steel truss pieces. And the rigidity element is arranged between the two connecting pieces and is used for supporting the two adjacent steel truss pieces. The temporary restraint system has the beneficial effects that the temporary restraint system with the rigidity elements and the damping elements connected in parallel is installed between the upper chords and the lower chords, it can be guaranteed that the adjacent steel truss girder sections form a continuous restrained whole in the construction process, and when the suspension bridge in the construction state is in any state and suffers from the wind load effect, the suspension bridge cannot be damaged. Relative displacement between the lower chords is slow, damping is provided for a suspension bridge system in a construction state by the temporary restraint system, and power performance such as wind resistance and shock resistance is improved.
本发明公开了一种阻尼防撞抗风限位装置、悬索桥钢桁梁及悬索桥，涉及悬索桥阻尼限位技术领域，包括：阻尼约束装置和铰接结构；阻尼约束装置包括连接件、刚度元件、阻尼元件；连接件包括两个，且相互平行，用于相邻的两个钢桁片连接；刚度元件，设置在两个连接件之间，用于支撑该相邻的两个钢桁片。本发明的有益效果是：通过上弦铰接，下弦杆之间安装刚度元件和阻尼元件并联的临时约束系统，能够保证相邻钢桁梁节段在施工过程中形成连续的受约束的整体，使施工状态的悬索桥在任意状态下，受到风荷载作用时，下弦杆之间的相对位移都是缓慢的发生，而且该临时约束系统为施工状态的悬索桥系统提供了阻尼，提升了抗风抗震等动力性能。
