Problems solved by technology

[0004] With regard to the related technologies mentioned above, the inventor believes that there are the following defects: the elevator has a certain height, and when the operator moves the elevator platform, the elevator platform is not only susceptible to greater resistance, which increases the movement resistance of the car body, but also increases the resistance of the car body on the road. When moving, it is not easy to pass under the road gantry, which brings inconvenience to the operator to move the cast-in-place box girder span of the bridge without support and convenient construction support

Description

technical field [0001] The invention relates to the field of construction brackets, in particular to a bridge cast-in-place box girder span without supports and convenient construction brackets. Background technique [0002] With the continuous increase of traffic demand, bridges are becoming more and more common in our daily life, and the construction technology of bridges is becoming more and more developed. Among them, bridges built with box girders are called box girder bridges. Box girders are widely used in highway bridge construction. widely. The construction technology involved in the construction of the box girder is very comprehensive and complex, and the requirements are also very high. Deviations may affect the final project quality. [0003] Notification number is that the Chinese patent of CN213772976U discloses a kind of bridge cast-in-place box girder span without supporting convenient construction bracket, comprises car body, and the top of car body is fixe...
