Steel internal mold for anchoring area of concrete bridge tower and construction method of steel internal mold
The invention relates to the technical field of bridge construction, and discloses a steel internal mold for a concrete bridge tower anchoring area, the steel internal mold comprises tower column internal molds and twisted steel, each tower column internal mold is a box body formed by welding steel plates, the periphery of each box body is closed, the upper portion and the lower portion of each box body are open, the number of the tower column internal molds is multiple, and the multiple tower column internal molds are welded together end to end; a plurality of twisted steel bars are welded and fixed on the outer side wall of the tower column inner mold; according to the construction method, a technical means of a permanent steel inner mold is provided, according to the geometric configuration of a concrete bridge tower anchoring area, steel plates are welded into a plurality of semi-closed box bodies to serve as tower column inner molds, twisted steel is welded to the sides, making contact with concrete, of the steel plates, and when the bridge tower anchoring area is constructed, the inner mold steel boxes are hoisted in a segmented mode, and adjacent segments are welded into a whole; during concrete pouring, the steel plate box serves as an inner formwork, the twisted steel bars are embedded in the tower column, after concrete pouring of the anchoring area is completed, the steel inner formwork does not need to be disassembled and participates in bridge tower stress in the later period, and the construction method reduces high-altitude operation and improves construction precision and construction efficiency.
本发明涉及桥梁施工技术领域，且公开了一种用于混凝土桥塔锚固区的钢内模，包括塔柱内模和螺纹钢筋，所述塔柱内模是使用钢板焊接形成四周闭合上下开口的箱体，所述塔柱内模的数量为多个，多个所述塔柱内模首尾焊接在一起，所述塔柱内模的外侧壁焊接固定有若干个所述螺纹钢筋；本发明中，该工法提出一种永久钢内模的技术手段，根据混凝土桥塔锚固区几何构形，使用钢板焊接成多个半封闭箱体作为塔柱内模，钢板与混凝土接触一侧焊接螺纹钢筋，桥塔锚固区施工时，内模钢箱分节段吊装，相邻节段焊接成整体，混凝土浇筑时钢板箱体作为内模板，螺纹钢筋埋入塔柱中，锚固区混凝土浇筑完成后，钢内模无需拆卸，后期参与桥塔受力，该施工工法减少高空作业，提高施工精度与施工效率。
