[0057] The implementation principle of the mold for manufacturing a thin concrete truss floor deck in the embodiment of the present application is as follows:

[0058] During the floor decking manufacturing process, the first bracket 2 and the second and third brackets 4 are appropriately sized based on the length of the floor decking. The first bracket 2, the second bracket 4, and the third bracket 4 form a fixed support frame.

The reciprocating screw 61 drives the sliding block 62 to move along the length of the sliding slot 41. The sliding block 62 causes the fourth bracket 5 to move laterally, achieving adjustment in the width direction of the mold.

[0059] When the mold adjustment is completed, the operator drives the rotating rod 71 to rotate in the opposite direction. The first pawl 723 is compressed by the reverse tooth surface resistance of the inner ratchet 722 to compress the first spring 724. The first pawl 723 and the inner ratchet 722 are disengaged. The outer ratchet 731 abuts against the second pawl 733. The second pawl 733 limits the outer ratchet 731. The outer ratchet 731 pushes the first bevel gear 732 to rotate synchronously through the second pawl 733. The first bevel gear 732 drives the second bevel gear 82 to rotate. The second bevel gear 82 drives the drive shaft 811 to rotate. The drive shaft 811 drives the third gear 83 to rotate. The third gear 83 meshes with the rack 84. The third gear 83 slides along the length direction of the rack 84. The third gear 83 drives the first gear 721 to disengage from the second gear 725.

[0060] When the truss reinforcement is placed in the template, the operator places the compression rod on the truss reinforcement, and the operator rotates the first screw 913 and the second screw 933. The first screw 913 drives the first compression rod 92 to compress the truss reinforcement, and the second screw 933 drives the second compression rod 94 to compress the truss reinforcement.

When there are no more obvious bubbles on the surface of the concrete, and the concrete is evenly and densely filling every corner of the mold, the vibration can be stopped. After the vibration work is completed, steam and water curing are carried out. Before curing, the prefabricated components are kept at room temperature for 2h-6h, and the heating and cooling rates are controlled within 20℃ / h. The maximum curing temperature is controlled within 70℃, and the difference between the surface temperature of the prefabricated component curing kiln and the ambient temperature is controlled within 25℃;
