High-strength bolt connection I-shaped straight web steel beam composite beam and construction method
The invention relates to a high-strength bolt connection I-shaped straight web steel beam composite beam and a construction method. Longitudinal beam I-shaped steel unit pieces adopt assembling jig frames with temporary stable adjusting devices and are fixed to the temporary stable adjusting devices of butt joints of cover beam sections; bolting the construction bracket and the operation platform by adopting a parallel connection and a main longitudinal beam; a bridge floor steel bar binding type steel support placing technology, a flange plate overhanging and hanging formwork supporting pouring technology and a bridge floor concrete pouring movable operation platform are researched and developed. According to the invention, an adjustable assembly jig frame structure is adopted, so that accurate adjustment and positioning of segments are realized; the mounting precision and the construction efficiency of the superposed beam are improved through the adjustable shelving support and the bolting type connecting system; the material storage platform steel frame is used as a support, the suspenders and the channel steel underframe are installed to complete flange plate formwork erecting construction, formwork erecting efficiency is improved, and good technical and economic benefits can be obtained when the formwork erecting device is applied to actual engineering.
本发明涉及一种高强螺栓连接工字型直腹板钢梁叠合梁及施工方法，纵梁工字钢单元件采用带临时稳固调整装置拼装胎架，固定于盖梁梁段对接接头临时稳固调整装置；采用平联与主纵梁栓接施工支架与操作平台；研发了桥面钢筋绑扎型钢支架搁置技术、翼缘板悬挑吊挂支模浇筑技术、桥面混凝土浇筑移动式操作平台。本发明采用可调式拼装胎架结构，实现了节段精确调整定位；通过可调式搁置支座、栓接式联结系，提高了叠合梁安装精度和施工效率；以存料平台钢架为支撑，安装吊杆、槽钢底架完成翼缘板支模施工，提高了模板支设效率，应用于实际工程中可取得较好的技术经济效益。
