Cast-in-place concrete arc-shaped beam and construction method
The invention relates to a cast-in-place concrete arc-shaped beam and a construction method. According to the scheme, the cast-in-place concrete arc-shaped beam comprises a steel bottom die, steel side dies, a reinforcement cage, and opposite pull rods. The top of the steel bottom die is detachably connected with the bottoms of the two steel side dies to form a pouring area for pouring the arc-shaped beam; the reinforcement cage is arranged in the pouring area; the opposite pull rods are detachably arranged between the two steel side dies; and a plurality of detachably connected supporting structures are arranged at the bottom of the steel bottom die. The method includes the steps that observation points and the central axis of the arc-shaped beam are set; a supporting frame is positioned, and a cross beam is installed on the supporting frame; steel bottom formworks are manufactured; the multiple steel bottom formworks are spliced to form a curve steel bottom formwork; according to the observation points, the position of the arc-shaped beam is paid off on the steel bottom dies, and the central axis of the arc-shaped beam and the side line of the arc-shaped beam are determined; the steel side dies are mounted on the steel bottom die according to the side line of the arc-shaped beam to form the pouring area; and the reinforcement cage is placed in the pouring area. The cast-in-place concrete arc-shaped beam has the advantages that the construction difficulty is remarkably reduced, the construction efficiency is improved, and the construction quality is guaranteed.
本发明涉及一种现浇混凝土弧形梁及施工方法，该方案包括钢底模、钢侧模、钢筋笼及对拉杆；钢底模顶部与两个钢侧模底部可拆卸连接形成供弧形梁浇筑的浇筑区域；钢筋笼设于浇筑区域内；对拉杆可拆卸设于两个钢侧模之间；钢底模底部设有多个可拆卸连接的支撑结构，方法包括设定观测点和弧形梁中轴线；定位支撑架并在支撑架上安装横梁；制作钢底模板；多个钢底模板拼接形成曲线钢底模；根据观测点，在钢底模上进行弧形梁位置放线，确定弧形梁中轴线和弧形梁边线；根据弧形梁边线在钢底模上安装钢侧模形成浇筑区域；将钢筋笼放置于浇筑区域内；在浇筑区域浇筑混凝土，本发明具有显著降低施工难度，提高施工效率，保证施工质量的优点。
