[0035] In specific work, the long-line table mold is cleaned by manual or cleaning spraying machine, the debris on the long-line table mold is removed, and the mold release agent is uniformly sprayed. The side mold is placed on the long-line table, and then the prestressed steel bar is placed on the long-line table, and the two ends of the steel bar are fixed on the tensioning beam and the fixed pedestal respectively. The steel bar is combed by the film covering and combing and separating integrated machine 60. After the combing is completed, the numerical control hydraulic tensioning machine 20 is started to tension the prestressed steel bar as a whole. After the steel bar is tensioned, the tensioning length is measured to detect whether the tensioning force meets the requirements. At the same time, according to the required length of the composite slab, the film covering and combing and separating integrated machine is used to place the separating plate, and the embedded part is installed in the composite slab.

After the concrete reaches the tensioning strength, the stiffening rib is installed above the prestressed composite slab and connected with the bottom plate to form a whole. Thereafter, the tensioning treatment is performed, the steel bar is cut at the reserved space of the separating plate, and the composite slab can be demolded and transported after the cutting is completed.

The compression longitudinal beam is composed of a plurality of prefabricated concrete pipe piles, and the concrete pipe piles are connected by flanges, so that the flow line equipment can be quickly installed, disassembled and replaced.
[0037] The production line proposes to set steel sleeve shoes at both ends of the compressed stringers, so that the pulling force borne by the fixed cross beam can be evenly transmitted to the compressed stringers on both sides in the form of concentrated load, preventing the stress concentration of the compressed stringers from causing the extrusion damage of the side concrete, and ensuring the safe and stable arrangement of the whole system and the reasonable stress.
