Description

Technical Field

[0001] The invention relates to the technical field of processing prefabricated bridge components, and in particular to a processing device for prefabricated assembled bridge components. Background Art

[0002] At present, when a bridge is erected, its concrete components are prefabricated in the factory and then transported to the site for assembly. This can speed up construction efficiency. When the prefabricated components are processed in the factory, they are generally grouting and solidifying through molds on the processing mold table, and then demolding is performed after forming.

[0003] Then, the current mold is more troublesome when forming the frame. It is necessary to manually move the mold, position and fix the mold, which is prone to inaccurate positioning. In addition, when the prefabricated components are cast, the double-layer steel trusses inside will be erected at different heights in the mold through metal parts. In this way, after the concrete is poured and solidified, it will remain in the prefabricated components, thereby increasing the material cost of the prefabricated components. For this reason, we have designed an assembled bridge prefabrication processing device.

[0094] The erection of the double-layer steel truss is firstly to erect the double-layer steel truss at the height of the fixing hole 43 by means of tools such as jacks, so that the fixing blocks at the ends of the steel truss are butted, and then the power assembly 45 pushes the fixing plate 42 to move a small distance inward, so that the ends of the double-layer steel truss are inserted into the fixing hole 43, and then the jacks and other tools are pulled out, and at the same time, the connection between the fixing plate 42 and the side mold 2 and the connection between the fixing hole 43 and the fixing plate 42 are sealed (wherein, the distance of pushing the fixing plate 42 in is small, so that the ends of the double-layer steel truss can be erected in the fixing hole 43, so that the model of the bridge prefabricated component after grouting molding is not affected within the error range);
