Counter-force frame for cable saddle incremental launching construction
The invention discloses a counter-force frame for cable saddle incremental launching construction. The counter-force frame and a grid embedded in a main tower are of a split structure. When the cable saddle is subjected to incremental launching construction, the counter-force frame is fixed on the side span side of the main tower and is matched with the grating; the counter-force frame is provided with a box-type base body and a plurality of groups of counter-force seats, a plurality of groups of through holes are formed in the box-type base body, and the groups of counter-force seats are connected to a rear end plate of the box-type base body side by side at intervals and are of an integral structure with the box-type base body; when the side span side of the main tower is fixed, the front end plate of the box type base body is close to the side span side tower wall of the main tower, all the penetrating holes in the box type base body and all the tensioning channels in the main tower form a one-to-one corresponding matching relation, and all the prestress tensioning assemblies penetrating out of the corresponding tensioning channels in the main tower are anchored at the position of the rear end plate of the box type base body. The overall structural strength is high, the anchoring stress acted by the prestress tensioning assembly can be reliably diffused, the situation that local stress is too large is avoided, and the main tower is relatively friendly to a concrete structure forming the main tower.
本发明公开了一种索鞍顶推施工用反力架，其与主塔所预埋格栅为分体结构；在对索鞍进行顶推施工时，反力架固定在主塔的边跨侧、与格栅相配合；所述反力架具有箱型基体和多组反力座，箱型基体上开设有多组穿孔，各组反力座间距并排连接在箱型基体的后端板上、与箱型基体为整体结构；在主塔的边跨侧固定时，箱型基体的前端板靠近主塔的边跨侧塔壁，箱型基体上的各穿孔与主塔上的各张拉通道形成一一对应配合关系，经主塔上的对应张拉通道而穿出的各预应力张拉组件分别在箱型基体的后端板处锚固。本发明的整体结构强度高，且能够将预应力张拉组件所作用的锚固应力可靠地扩散开、以避免局部应力过大，对构成主塔的混凝土结构相对友好。
