Fabricated spandrel girder structure and construction method
The invention discloses a construction method of a fabricated spandrel girder structure. The method comprises the following steps: an internal steel bar structure is arranged according to a common fabricated spandrel girder, and longitudinal bars penetrate through steel bar round holes; the fabricated spandrel girder structure is poured; firstly, one fabricated spandrel girder structure is placed on a bearing column, and a lever rod is installed on a trapezoidal bearing frame body; the other fabricated spandrel girder structure is in butt joint with the lever rod; the interior is filled with an elastic rust-proof protective layer at high pressure, and protective putty is applied by smearing after the exterior is connected with a fixing block. According to the fabricated spandrel girder structure and the construction method, the design is scientific and reasonable, the structure for improving the high-speed rail elevated box girder is provided, in-situ casting of the spandrel girder in the prior art is avoided, and the mechanical strength is high; the creative connection mode not only avoids the problem that the joint is easy to break, but also prevents the supporting end from tilting when the middle part of the spandrel girder is stressed; and the structure is simple, the construction is fast, the cost is low, and popularization is worthy.
本发明公开了一种装配式承重梁施工方法，包括以下步骤，根据普通装配式承重梁配好内部钢筋结构，纵筋穿过钢筋圆孔后；浇筑好预制的装配式承重梁结构；先把一个装配式承重梁结构放置在承重柱上，安装杠杆棒到梯形承重框体上；另外一个装配式承重梁结构对接杠杆棒；内部高压填充弹性防锈保护层，外部连接好固定块后涂抹保护腻子。本发明配式承重梁结构及施工方法设计科学合理，提供改良高铁高架箱梁的结构，避免了现有技术中现场浇筑承重梁，而且力学强度大。开创性的连接方式，不仅避免了连接处容易断裂的问题，也避免了承重梁中部受力时使支撑端翘起。结构简单，施工快捷，成本低，值得推广。
