Preferably, the top bracket is a 10# I-steel.
Preferably, the hanger rod is made of 25 phi finish-rolled deformed steel.
Preferably, the top plate and the bottom plate are made of 12 x 30 x 3cm Q235 steel plates, and holes matched with the hanging rods are reserved on the top plate and the bottom plate.
Preferably, the top plate is welded to the upper end flanges of the two sets of top brackets.
Compared with the prior art, the invention has the beneficial effects that:
1) this gallows of setting up of construction platform of construction behind public road bridge post tie beam under construction, convert the upper portion by traditional lower part pressurized system and draw the system, it is little to have the dead weight, ann tears the convenience open, low cost, safe and reliable and be convenient for have enough to meet the need the characteristics of utilization, effectively solved under the current bent cap newly-increased post tie beam construction platform because of the through hole does not reserve, the staple bolt is difficult to the installation and can't set up difficult problem in the limited height, newly-increased tie beam construction provides effectual solution for under the current bent cap, construction progress has been accelerated.
2) According to the hanging bracket erected on the construction platform constructed after the bridge and the column of the road under construction are tied, the top bracket adopts double-spliced 10# I-steel, and the top bracket, the hanging rod and the bottom plate form the whole supporting system. The main function is to transmit the constructed structure and other loads to the constructed capping beam. The steel is an economical section steel with better section mechanical property, and has wide flange, large lateral rigidity, strong bending resistance and convenient turnover.
3) According to the hanger erected on the construction platform constructed after the bridge and column tie beam of the road under construction, the hanger rod is used as a main stressed component of the whole hanger system and is made of phi 25 finish rolled deformed steel bar, the tensile strength of the hanger is high, and the hanger can be used with a matched nut to freely adjust the position of the whole support system in the vertical direction.
4) The hanging bracket erected on the construction platform constructed after the bridge columns of the highway under construction are tied is simple in erection method, and the connection of the hanging rod and the top bottom plate only needs the matched nut and the steel plate to be stably connected. The top plate steel plate and the top bracket are firmly connected by full welding.
5) This gallows of setting up of construction platform of constructing behind highway bridge post tie beam has saved at least one third cost for the construction of staple bolt method, and the staple bolt at first needs set up the support, and the turnover cycle is long, and the cost is higher. This gallows is direct two unifications, can embody its advantage more to it is ann to tear fast open, has improved the construction progress.
