U-shaped aqueduct truss type all-steel formwork construction method
The invention discloses a U-shaped aqueduct truss type all-steel formwork construction method. A formwork used in the method comprises a steel bottom plate, a supporting frame, outer side formworks, a bottom formwork and an inner formwork. The steel bottom plate is arranged at the bottom, the supporting frame is erected above the steel bottom plate, the bottom formwork is arranged above the supporting frame, the bottom formwork is located in the middle of the bottom of the whole aqueduct formwork and used for being connected with the outer side formworks symmetrically arranged on the two sides, the inner side faces of the outer side formworks are in an arc shape attached to a U-shaped aqueduct, and the outer side faces of the outer side formworks are vertically provided with supporting columns on the inner sides. The inner formwork is arranged above the outer formwork, a reinforcement cage is arranged between the inner formwork and the outer formwork, and a U-shaped aqueduct pouring cavity is formed between the inner formwork and the outer formwork; and the inner formwork is of a U-shaped structure, and a plurality of pouring holes are formed in the inner formwork. According to the U-shaped aqueduct truss type all-steel formwork construction method, one-time forming construction of aqueduct reinforced concrete is achieved through the formworks, the stable structure guarantees the forming section of the aqueduct, and the pouring holes are reasonably formed so that the flow passing face of the aqueduct can be smooth and flat; and the whole truss structure is not provided with concrete-penetrating opposite-pulling steel bars, so that the hidden danger of overflowing leakage corrosion of the aqueduct caused by the concrete-penetrating opposite-pulling steel bars is solved.
本发明公开了一种Ｕ型渡槽桁架式全钢模板施工方法，该方法所用的模板包括钢底板、支撑架、外侧模、底模和内模；所述钢底板设在底部，支撑架搭设在钢底板的上方，支撑架上方设有底模，底模位于整个渡槽模板底部的中间位置，用于连接两侧对称设置的外侧模，所述外侧模内侧面为贴合U型渡槽的弧形，外侧面为垂直内侧设置支撑柱；所述内模设在外侧模上方，内模与外侧模之间设有钢筋笼，内模和外侧模间形成U型渡槽浇筑腔体；内模为U型结构，内模上设有多个浇筑孔。本方法采用的模板解决渡槽钢筋砼一次成型施工，稳定的结构既保证渡槽的成型断面，合理设置浇灌孔使渡槽过流面光滑平整；整体的桁架结构不设置穿砼对拉钢筋，解决了穿砼对拉筋导致渡槽过流渗漏腐蚀的隐患。
