Steel-concrete composite beam suitable for integral carrying installation and construction method of steel-concrete composite beam
The invention discloses a steel-concrete composite beam suitable for integral carrying installation and a construction method of the steel-concrete composite beam. A top plate supporting system is erected in a channel beam to provide stable support for construction of a bridge deck located over the channel beam, and flange plate supporting systems are erected on the outer sides of the two sides of the channel beam to provide support for construction of flange plates of the bridge deck; a supporting system is not erected below the bottom plate of the channel beam, and in this way, the stress state of the bridge deck is not changed before and after the whole steel-concrete composite beam is jacked in the follow-up carrying stage, the construction safety of the bridge deck is guaranteed, and the situation that in the prior art, due to the fact that a supporting system is also arranged below the bottom plate of the channel beam in advance, when the steel-concrete composite beam is jacked, the bridge deck slab is pulled to deform and crack is avoided. Meanwhile, the end partition plates and the transverse partition plates are arranged in the channel beams, and end cross beams and middle cross beams are connected between the pair of channel beams, so that the rigidity of all the structures in the steel-concrete composite beam is enhanced, the steel-concrete composite beam can be suitable for overall carrying installation, and therefore the construction efficiency is improved.
本发明公开了一种适用于整体驮运安装的钢混组合梁及其施工方法，通过在槽形梁的内部搭设顶板支撑系统对位于槽形梁正上方的桥面板施工提供稳固支撑，在槽形梁的两侧外侧搭设翼缘板支撑系统对桥面板的翼缘板施工提供支撑，而未在槽形梁的底板下方搭设支撑系统，这样在后续驮运阶段顶升整个钢混组合梁的前后，桥面板受力状态不变，保证了桥面板施工的安全性，避免现有技术中预先在槽形梁底板下方也设置支撑系统而导致顶起钢混组合梁时，桥面板受拉变形开裂，同时通过在槽形梁内部设置端隔板、横隔板，在一对槽形梁之间连接设置端横梁和中横梁，加强了钢混组合梁内部各处结构的刚度，使得钢混组合梁能够适用于整体驮运安装，从而提高施工效率。
