Large-span box-type steel beam sliding installation construction process and device
The invention discloses a large-span box-type steel beam sliding installation construction process and device, and relates to the technical field of structural engineering. Thick rail pressing platesare arranged on the upper portions of the two sides of the lower end of a sliding rail, a jig frame and a wedge-shaped clamping block are arranged at the upper end of the sliding rail in a sliding mode, square steel is fixedly arranged on the two sides of the upper end of the jig frame, a to-be-installed steel beam is clamped at the upper end of the jig frame through the square steel, and a pushing lug plate is arranged on the outer surface of the to-be-installed steel beam; the fixed end of a hydraulic oil cylinder is rotationally connected with the pushing lug plate, a hydraulic crawl deviceis in rigid connection with a to-be-slid component, and the connection mode is good in synchronism control over all sliding (pushing) points when the sliding span and the spacing distance are large and the number of trusses is large, so that the problem that the in-place accuracy of the steel beam is not high is solved; and the assembly and accumulated slippage of each unit structure can be constructed at the same time and do not influence each other, and the absolute time of hydraulic slippage operation is short so that the installation period of a roof box girder can be effectively ensured.
本发明公开了一种大跨度箱型钢梁滑移安装施工工艺及装置，本发明涉及结构工程技术领域。通过滑移轨道的低端两侧上部处设置有厚轨道压板，滑移轨道的上端上滑动设置有胎架和楔形夹块，胎架的上端两侧均固定设置有方钢，胎架的上端位置处通过方钢卡装有待安装钢梁，待安装钢梁的外表面上设置有顶推耳板，液压油缸的固定端与顶推耳板之间转动相连，液压爬行器与待滑移构件间采取刚性连接的方式，该连接方式对于滑移跨度及跨距较大、榀数较多的结构时，其各滑移(顶推)点的同步性控制较好，解决了钢梁就位准确性不高的难题，并且每榀单元结构的拼装与累积滑移可同时施工，互不影响，加之液压滑移作业绝对时间较短，能够有效保证屋面箱梁的安装工期。
