Ground anchor type cable-stayed bridge midspan axial-force-free connecting device and mounting method thereof
The invention discloses a ground anchor cable-stayed bridge midspan axial-force-free connecting device and a mounting method thereof.The ground anchor cable-stayed bridge midspan axial-force-free connecting device comprises an outer sleeve large steel box girder and an embedded small steel box girder, a plurality of support cross beams are arranged on the inner periphery of the outer sleeve large steel box girder, and transverse spherical supports or vertical spherical supports are arranged on the support cross beams; the embedded small steel box girder is fixedly supported in the outer sleeve large steel box girder through the transverse spherical supports and the vertical spherical supports; the transverse spherical supports in the same section are symmetrically arranged, and the vertical spherical supports in the same section are also symmetrically arranged; according to the connecting device without the axial force, due to the arrangement of the structure, the longitudinal large displacement and additional stress caused by a large-span bridge under the effects of temperature difference changes, concrete shrinkage, creep, earthquakes and the like can be effectively solved, the stress performance of the large-span bridge is effectively improved, and the larger spanning and passing capacity of a modern bridge is achieved; and the whole structure system is smooth in force transmission, convenient to construct, and relatively convenient to operate, maintain and replace.
本发明公开一种地锚式斜拉桥跨中无轴力连接装置及其安装方法，包括外套大钢箱梁和内嵌小钢箱梁，所述外套大钢箱梁的内周布置有若干支座横梁，所述支座横梁上设置有横向球形支座或者竖向球形支座，所述内嵌小钢箱梁通过若干所述横向球形支座和所述竖向球形支座固定支撑在所述外套大钢箱梁内；同一断面内的所述横向球形支座对称设置、所述竖向球形支座也对称设置；本无轴力连接装置通过上述结构的设置能够有效解决大跨度桥在温差变化、混凝土收缩、徐变和地震等作用下引起的纵向大位移和附加应力，有效改善大跨度桥梁受力性能，实现现代桥梁更大的跨越和通行能力；而且整个结构体系传力顺畅、施工便利，运营维护和更换也较为方便。
