Construction method of large-span large-section steel structure beam
The invention discloses a construction method of a large-span large-section steel structural beam. The construction method comprises the steps that the large-span large-section steel structural beam is divided into a plurality of beam sections; structural columns are erected at the two opposite ends of the installation position of the large-span large-section steel structural beam, and steel corbels are installed on the opposite sides of the two structural columns. A plurality of counter-force frames are erected on the installation position, and the counter-force frames are arranged at the butt joint position of every two adjacent beam sections or below the butt joint position of the large-span large-section steel structure beam and the bracket; an arching jack is installed on the counter-force frame; the beam section is hoisted, so that the two ends of the beam section are placed on the two adjacent counter-force frames respectively; a plurality of arching jacks are used for adjusting the inclination of a plurality of beam sections; the multiple beam sections are connected in a butt joint mode to form the large-span large-section steel structure beam, and the beam sections at the two ends of the large-span large-section steel structure beam are connected with the steel corbels. The problem that a conventional hoisting construction method for the steel structural beam is not suitable for construction of the large-span large-section steel structural beam is solved.
本发明公开了一种大跨度大截面钢结构梁的施工方法，包括：将大跨度大截面钢结构梁划分为多个梁段；于大跨度大截面钢结构梁的安装位置的相对两端架设结构柱，两个结构柱的相对侧安装有钢牛腿；于安装位置上架设多个反力架，反力架设置于相邻两个梁段的对接处或大跨度大截面钢结构梁与牛腿对接处的下方；于反力架上安装起拱千斤顶；吊装梁段，使得梁段的两端分别搁置于相邻两个反力架上；多个起拱千斤顶调整多个梁段的倾斜度；将多个梁段对接连接形成大跨度大截面钢结构梁以及大跨度大截面钢结构梁的两端的梁段与钢牛腿连接。本发明解决了常规钢结构梁的吊装施工方法不适用大跨度大截面钢结构梁的施工的问题。
