Construction method for bracket steel anchor beam of main tower of cable-stayed bridge
The invention relates to a cable-stayed bridge main tower bracket steel anchor beam construction method. The method comprises the following steps that steel anchor beams are assembled in a factory; carrying out field trial splicing on the steel anchor beam; constructing a steel anchor beam positioning bracket; hoisting the steel anchor beam; and mounting the steel anchor beam. The bracket steel anchor beam assembling jig frame and the in-situ jig frame have the beneficial effects that the bracket steel anchor beam assembling jig frame and the in-situ jig frame are developed, efficient assembling of complex bracket steel anchor beams in a factory area and a construction site is met by changing the structural design, and the manufacturing precision of the bracket steel anchor beams is improved; a steel anchor beam positioning support is developed, a steel anchor beam high-precision positioning platform is composed of a following device, a jack and the like, the positioning precision of the steel anchor beam is improved, and the construction difficulty is reduced; a steel anchor beam inverted-sequence installation technology is provided, a temporary fixing support is pre-buried in the tower before the main tower is poured, the pre-burying precision of a steel anchor beam bracket is improved, and the construction quality is improved.
本发明涉及一种斜拉桥主塔牛腿钢锚梁施工方法，包括以下步骤：钢锚梁工厂组拼；钢锚梁现场试拼；钢锚梁定位支架施工；钢锚梁吊装；钢锚梁安装。本发明的有益效果是：研制了牛腿钢锚梁拼装胎架和原位胎架，通过改变结构设计满足复杂牛腿钢锚梁在厂区和施工现场的高效拼装，提高了牛腿钢锚梁制造精度；研制了钢锚梁落位支架，由跟随装置和千斤顶等组成的钢锚梁高精度落位平台，提高了钢锚梁的定位精度，降低了施工难度；提出了钢锚梁逆序安装技术，主塔浇筑前在塔内预埋临时固定支架，起到了钢锚梁牛腿的预埋精度，提高了施工质量。
