Folding telescopic triangular bracket and construction method thereof
The invention discloses a folding telescopic triangular bracket and a construction method thereof.The triangular bracket comprises a corbel, a vertical rod, an inclined rod, a chord member and a telescopic chord member, the lower end of the vertical rod is hinged to the upper portion of the corbel, a pin hole is formed in the lower section of the vertical rod, and the lower end of the inclined rod is hinged to the upper portion of the corbel; the rear portion of the lower side of the chord member is connected with one of the pin holes in the upper end of the vertical rod or the lower section of the vertical rod, the front portion of the lower side of the chord member is hinged to the upper end of the inclined rod, and the telescopic chord member and the front section of the chord member are slidably sleeved and positioned through a pin shaft. The construction method comprises the steps of pier column construction, bracket embedded part installation, bracket pull rod installation, bracket pre-pressing test, bracket hoisting, transverse connection installation between brackets, pull rod pre-tightening, installation of other parts and formworks of the support, structure construction, bracket dismantling, folding and warehousing and the like. The method has the characteristics of no need of on-site high-altitude welding, low construction difficulty, small potential safety hazard, short construction time, high cyclic utilization rate, lower cost, few scattered parts, easiness in storage and wide application range.
本发明公开了一种折叠伸缩式三角托架及其施工方法，三角托架包括牛腿、竖杆、斜杆、弦杆和伸缩弦杆，竖杆的下端铰接于牛腿的上方，竖杆的下段设有销孔，斜杆的下端铰接于牛腿的上方，弦杆的下侧后部与竖杆的上端或竖杆下段的销孔择一连接，弦杆的下侧前部与斜杆的上端铰接，伸缩弦杆与弦杆的前段滑动套设且两者通过销轴进行定位。施工方法包括墩柱施工、托架预埋件安装、托架拉杆安装、托架预压试验、托架吊装、托架间横联安装、拉杆预紧、支架其他部分及模板安装、结构物施工、托架拆除以及折叠入库等。具有不需要现场高空焊接、施工难度小、安全隐患小、施工时间短、循环利用率高、成本较低、零散件少、易保管、应用范围广的特点。
