Precast beam longitudinal and transverse slope wedge block accurate adjustment construction method and device
The invention relates to a precast beam longitudinal and transverse slope wedge block accurate adjustment construction method and device, and the construction method comprises the following construction steps: a, arranging transverse support profile steel on a support base, welding longitudinal support profile steel on the transverse support profile steel to connect the transverse support profile steel, welding a support steel plate on the longitudinal support profile steel, and connecting a precast beam template system; b, distributing hydraulic jacks at four corners of the wedge block according to the size of the wedge block, freely lifting the hydraulic jacks according to design requirements to adjust longitudinal and transverse gradients, supporting and placing adjusting steel plates on piston stroke shafts of the hydraulic jacks, and changing the size of the adjusting steel plates according to different lengths, orthogonality or oblique crossing of the precast beams; c, installing the outer molds on the outer side of the precast beam pedestal, connecting and fixing the outer molds on the two sides through pull rods, placing the inner mold on an adjusting steel plate, and fixing the upper portion of the inner mold through a pressing rod. According to the adjustment construction method and device, the adjusting precision is high, influences caused by some unfavorable climatic environments can be well resisted, operation is easy, and the construction efficiency can be improved.
预制梁纵横坡楔形块精确调节施工方法及装置，施工步骤为：a、在支撑底座上设置横向支撑型钢，在横向支撑型钢上焊接纵向支撑型钢将横向支撑型钢联系起来，在纵向支撑型钢上焊接支撑钢板，连接预制梁模板体系；b、液压千斤顶根据楔形块尺寸分配在楔形块的四个角，液压千斤顶根据设计要求自由升降来调节纵横坡度，在液压千斤顶的活塞行程轴上支撑放置调节钢板，调节钢板根据预制梁的不同长度，正交或斜交来变换尺寸；c、将外模安装在预制梁台座外侧，用拉杆将两侧的外模连接固定，内模放置在调节钢板上，上部用压杆固定。本调节施工方法及装置调节精准度高，能较好地抵御一些不利的气候环境带来的影响，且操作简单，能够提高施工效率。
