In order to overcome the defect that the bridge steel box girder is inconvenient to disassemble in the prior art, one of the purposes of the utility model is to provide a municipal bridge steel box girder structure.
One of the purposes of the utility model is realized by adopting the following technical scheme: a municipal bridge steel box girder structure, comprising a transverse plate: the lower side of the transverse plate is fixedly connected with a bottom frame, the upper sides of the left end and the right end of the transverse plate are respectively provided with a connecting side plate, the connecting side plates are in U-shaped structure, the upper sides of the connecting side plates are provided with bridge top plates, and the outer sides of the connecting side plates are provided with stabilizing units;
The utility model discloses a firm unit, including the curb plate, the curb plate is connected to the connecting plate, the connecting plate sets up in the outside at both ends about the curb plate, upper and lower both sides be provided with firm board between the connecting plate, the equal fixedly connected with installation piece in the left and right sides of firm board, the mounting hole has all been seted up in the outside of bridge roof, connection curb plate, connecting plate and installation piece, be provided with the firm pole between diaphragm and the bridge roof, the outside at both ends all sets up the external screw thread about the firm pole.
According to the municipal bridge steel box girder structure, the stabilizing plates are arranged in an X-shaped structure.
According to the municipal bridge steel box girder structure, the inner side of the mounting hole is provided with internal threads, and the internal threads are arranged in an adaptive manner with external threads. The bridge steel box girder is convenient to install by the stabilizing rod.
According to the municipal bridge steel box girder structure, a plurality of mounting holes and stabilizing rods are formed in the steel box girder structure.
According to the municipal bridge steel box girder structure, a filler is arranged between the connecting plate and the bridge roof.
According to the municipal bridge steel box girder structure, the filler is made of concrete materials. And the bridge roof is convenient to reinforce.
The beneficial effects are that:
1. Through being provided with connection curb plate, connecting plate, firm board, a plurality of mounting holes and firm pole, be convenient for through rotating firm pole, convenient quick dismantlement with the bridge roof to conveniently install, reduce staff's work load.
2. Through being provided with connecting plate, firm board, firm pole and installation piece, the steadiness of being convenient for increase the bridge roof makes whole steel case roof beam structural stability increase.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
