Reinforcing method for in-service expressway local structure defect portal frame type sign structure
The invention discloses an in-service expressway local structure defect portal frame type sign structure reinforcing method. The method comprises a reinforcing method for partial overall structure instability of a portal frame type sign structure and a transformation method for a local sign panel without steel pipe reinforcement. The reinforcing method for the overall structure instability of the partial portal type sign structure is modified in a welding and hoop mode and comprises the following steps that A1, in order to reduce welding, an upper inclined rod support, a lower inclined rod support and a steel plate are welded in advance, and anti-corrosion treatment of a steel structure is conducted; a2, a worker completes reinforcement and transformation of upper and lower inclined rod supports which are partially lost through bolt welding on site; according to the method, structural defect portal-type signs of different structural forms can be reinforced and transformed, the portal-type signs do not need to be integrally disassembled and returned to a factory, workers can conduct construction on site easily during transformation, construction can be completed only by closing a traffic lane locally for a short time on site, and the method is more convenient.
本发明公开了一种在役高速公路局部结构缺陷门架式标志结构加固方法，包括部分门架式标志结构整体结构失稳的加固方法和对局部标志面板未进行钢管加强的改造方法；所述部分门架式标志结构整体结构失稳的加固方法为采用焊接加抱箍的形式进行改造，包括如下步骤：A1、为减少焊接，预先对上下斜杆支撑与钢板焊接，并做好钢结构的防腐处理；A2、由工人现场通过螺栓焊接完成对局部缺失的上下斜杆支撑的加固改造；本发明可对不同结构形式的结构缺陷门架式标志进行加固改造，而不用将门架式标志整体拆卸回厂，且在改造时工人现场施工简单，现场只需局部短时封闭行车道即可完成施工，更具便利性。
