Large-span bridge sidewalk and non-motorized vehicle lane telescopic device
The invention particularly relates to a large-span bridge sidewalk and non-motorized vehicle lane telescopic device. The telescopic device is characterized by comprising a supporting beam, one end ofthe supporting beam is connected with the main beam on one side of the telescopic joint through a pin hinge structure, vertical support is provided for the supporting beam, a cambered surface slidingsupport is arranged at the other end of the supporting beam, a sliding groove is formed in the main beam on the other side of the telescopic joint, sliding connection is formed between the bottom of the cambered surface sliding support and the sliding groove, and a deformation gap is formed between the bottom of the supporting beam and the top of the sliding groove and can adapt to longitudinal deformation and rotational deformation. The sidewalk and non-motorized vehicle lane telescopic device is of a simply supported structure of the upper-layer cover plate and the lower-layer steel beam, isreliable in force transmission and low in construction cost, not only has the adaptive capacity of large-displacement stretching and rotating, but also has the anti-skid, dustproof and drainage functions, and is convenient to overhaul and maintain.
本发明具体涉及一种大跨度桥梁人行道及非机动车道伸缩装置，其特征在于所述伸缩装置包括支承梁，支承梁的一端通过销铰结构与伸缩缝一侧的主梁连接，为支承梁提供竖向支撑，支撑梁的另一端则设置弧面滑动支座，伸缩缝另一侧的主梁设有滑动槽，所述弧面滑动支座的底部与滑动槽之间形成滑动连接，支承梁底部与滑动槽顶部设变形间隙，能适应纵向变形和转动变形。本发明人行道及非机动车道伸缩装置为上层盖板、下层钢梁的简支结构，传力可靠，建设成本低，不仅具有大位移伸缩和转动的适应能力，而且具备防滑、防尘和排水功能，便于检修和维护。
