The composite driving mechanism comprises a first pushing ring 13 connected with the first pushing pin and a second pushing ring 14 connected with the second pushing pin, a plurality of elastic strips 15 are uniformly distributed between the first pushing ring and the second pushing ring in the circumferential direction so as to enable the first pushing pin and the second pushing pin to be relatively far away, and the projection of one end of each elastic strip on the first pushing ring and the projection of the other end of each elastic strip on the first pushing ring are distributed in a staggered mode.
After the manufacturing die of the assembled reinforced concrete U-shaped frame beam is installed, concrete is injected between the outer side die and the U-shaped thin steel groove inner die, and the concrete is gradually solidified along with the lapse of time; in the concrete solidification process, the first ejector ring 13 and the second ejector ring 14 respectively and correspondingly eject the first ejector pin and the second ejector pin towards two ends in the axial direction under the action of the elastic strip 15, so that the first ejector pin and the second ejector pin are relatively far away, the first ejector pin ejects lubricating oil liquid to enable the lubricating oil liquid to flow out from the liquid outlet hole 12, a layer of lubricating oil is coated on the outer surfaces of the first sleeve 6 and the second sleeve 7, the first sleeve 6 and the second sleeve 7 are isolated from the concrete, and the first sleeve 6 and the second sleeve 7 are prevented from being adhered to the concrete; in the process of the axial extension of the elastic strip 15, the elastic strip 15 rotates circumferentially at the same time, so the elastic strip 15 can drive the first sleeve 6 and the second sleeve 7 to rotate relatively, so that the first sleeve 6 and the second sleeve 7 always keep relative movement with concrete, and the concrete does not have enough time to be adhered to the first sleeve 6 and the second sleeve 7.
An embodiment 2 of a manufacturing mold of an assembled reinforced concrete U-shaped frame beam comprises an outer mold, a U-shaped thin steel groove inner mold and a traction mechanism playing a role in traction and fixation, wherein the traction mechanism comprises a first traction rod 1 and a second traction rod 2 which are oppositely arranged, the first traction rod and the second traction rod are connected through a connecting shaft 3, a first locking bolt 4 is arranged at the end part of the first traction rod, a second locking bolt 5 is arranged at the end part of the second traction rod, the first traction rod is sleeved with a first sleeve 6, the second traction rod is provided with a second sleeve 7, a first oil storage hole 8 is formed in the first sleeve along the direction of a central axis, a second oil storage hole 9 is formed in the second sleeve along the direction of the central axis, a first push pin 10 used for pushing oil is arranged in the first oil storage hole, a second push pin 11 used for pushing oil is arranged in the second oil storage hole, liquid outlet holes 12 communicated with the outside are densely distributed in the first oil storage hole and the second oil storage hole, and a composite driving mechanism used for enabling the first push pin and the second push pin to be relatively far away from the second sleeve and enabling the second sleeve to relatively move relatively is arranged between the first traction rod and the second pull rod.
