Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to an adjustable bending device for transportation road and bridge construction. Background Art

[0002] At present, during the construction of roads and bridges, some steel bars need to be bent for anchoring, and the bending of steel bars is easy to be carried out at room temperature. According to the current national standard GB50666-2011 "Concrete Structure Engineering Construction Code", Article 5.3.2 clearly stipulates that steel bar processing should be carried out at room temperature, and the steel bars should not be heated during the processing. The steel bars should be bent in place at one time, and the use of hot bending to bend the steel bars will cause annealing, resulting in a decrease in the strength of the steel. When bending steel bars of the same size, the position of the steel bar bending must be measured and marked each time the bending is performed, which is time-consuming and laborious. At the same time, the current device is not convenient for adjusting and fixing the steel bars according to the thickness of the steel bars. Therefore, we have launched a new adjustable bending device for transportation road and bridge construction. Utility Model Content
