Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated box girders, and more specifically, to a windproof reinforcement device for prefabricated box girders. Background Art

[0002] Box girder is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. Box girders of reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. Box girders prefabricated in an independent site can be erected in combination with a bridge-erecting machine after the lower project is completed, which can speed up the progress of the project and save construction time; cast-in-place box girders are mostly used for large continuous bridges. Commonly, they are divided into two types based on materials, one is prestressed reinforced concrete box girder, and the other is steel box girder. When erecting the prefabricated box girder, anchors are usually used to fix it on the pile foundation. In addition to using anchors, reinforced concrete pads can also be used to fix the prefabricated box girder on the pile foundation. After the prefabricated box girder is erected, it is at a high place. In severe weather such as strong winds, the side of the prefabricated box girder is blown by the wind, which can easily affect the stability of the prefabricated box girder installation. For this reason, we proposed a prefabricated box girder windproof reinforcement device. Utility Model Content
