[0002] Because the integrated construction of prefabricated box girder bridge deck is completed in the prefabricated beam yard, the bridge deck construction content in the beam yard is numerous, and the transportation of materials such as steel bar templates required for the integrated construction of the bridge deck has become an important issue. Generally, the integrated construction of the bridge deck is carried out in units of a box girder. After the construction is completed, the construction materials are transported by crane. The crane is frequently moved and the amount of materials hoisted at one time is small, resulting in low efficiency and affecting the construction period of the bridge deck. Since the bridge deck construction template is generally a wooden template, the crane is lifted and fixed at two points, which can easily cause the template to deform, and the qualified rate of the template and the thickness of the protective layer is greatly reduced. It is very difficult to accept and adjust the protective layer, and it is also very time-consuming.
