Construction method of inclined concrete-filled steel tubular column internally provided with reinforcing steel bars
The invention relates to a construction method of an inclined concrete-filled steel tube column internally provided with reinforcing steel bars, a plurality of circles of stud groups are arranged in a steel tube along the circumferential direction, and the construction method comprises the following steps: providing an arc-shaped supporting plate, the length of the arc-shaped supporting plate is the same as that of the steel tube, and the diameter of the arc-shaped supporting plate is not greater than the inner diameter of the whole circle of stud groups in the steel tube; the steel pipe is flatly placed on the ground, then the arc-shaped supporting plate is pushed into the steel pipe, the two ends of the arc-shaped supporting plate are flush with the head end and the tail end of the steel pipe respectively, and the peripheral face of the arc-shaped supporting plate abuts against the studs on the lower portion of the steel pipe in an attached mode. Aiming at the difficulty of mounting the reinforcement cage in the inclined steel pipe, the thought of fixing the prefabricated reinforcement cage with the steel pipe and integrally hoisting is determined, the distance between the reinforcement cage and the inner wall of the steel pipe is defined, and a non-contact lap joint connection mode between each section of reinforcement cage is provided; in the installation process, the supporting plate is used for overcoming the influence of studs in the steel pipe, the reinforcement cage is fixed by welding positioning ribs in batches, and the reinforcement cage and the steel pipe are integrally hoisted to install the reinforcement cage in the steel pipe.
本发明涉及一种内设钢筋的倾斜钢管混凝土柱施工方法，钢管内沿周向设有多圈栓钉组，步骤包括：提供弧形托板，所述弧形托板长度与钢管长度相同，且所述弧形托板的直径不大于钢管内整圈栓钉组的内径；将钢管平放在地面，然后将弧形托板推入钢管内并使弧形托板的两端分别与钢管的首端和尾端齐平，且弧形托板的外周面贴抵在钢管下部的栓钉上。本发明通过针对倾斜钢管内安装钢筋笼的难点，确定了预制钢筋笼并与钢管固定、整体吊装的思路，明确了钢筋笼与钢管内壁的间距，并提出每段钢筋笼之间非接触搭接的连接方式；在安装过程中利用托板克服钢管内栓钉影响、采用可分次焊接定位筋固定钢筋笼、钢筋笼与钢管整体吊装等方法进行钢管内钢筋笼的安装。
