The processing template structure includes two processing cross templates 2 arranged on the opposite side of the two processing side templates 1. There is a longitudinal reinforcement bar 3 between the two processing side templates 1. A transverse reinforcement bar 4 is wound around the outside of the longitudinal reinforcement bar 3. There is a hollow slab beam inner mold 5 between the two processing side templates 1. The longitudinal reinforcement bar 3 is located between the hollow slab beam inner mold 5 and the two processing side templates 1.

[0026] Among them, the longitudinal reinforcement bars 3 are evenly distributed around the hollow slab beam inner mold 5. The outer surface of the hollow slab beam inner mold 5 is in contact with the longitudinal reinforcement bars 3. The length of the longitudinal reinforcement bars 3 is greater than the length of the processing side templates 1. The longitudinal reinforcement bars 3 and the transverse reinforcement bars 4 form a steel bar mesh.

[0027] It should be noted that the number of processing cross templates 2 is multiple. The multiple processing cross templates 2 are evenly distributed between the two processing side templates 1. By setting the processing side templates 1 and the processing cross templates 2, a space template is formed between the processing side templates 1 and the processing cross templates 2. Then, by setting the hollow slab beam inner mold 5, when pouring the prestressed hollow slab beam, its interior can be in a hollow state, thereby improving the overall strength of the prestressed hollow slab beam.

[0028] In addition, the inner and outer molds of the prestressed hollow slab adopt integral large-sized fixed steel molds to reduce the number of joints. The steel plate thickness is 5 mm. The template structure adopts a fixed steel skeleton with a 5 mm steel plate veneer. The template skeleton is made of No. 8 channel steel. The longitudinal spacing of the channel steel is 75 cm, and the transverse spacing is 30 cm. The side mold joints form tongue-and-groove joints. The wharf longitudinal beams and panels adopt wooden templates, and the hollow panels adopt disposable hard plastic foam inner molds with a diameter of 300 mm.

[0029] In this embodiment, a positioning block 6 extending into the interior of the processing cross template 2 is fixedly connected to one side of the processing side template 1. A fixing bolt 7 extending into the interior of the positioning block 6 is threadedly connected to the top of the processing cross template 2.

[0030] Embodiment Two:

[0031] Please refer to Figures 1 to 4 , on the basis of Embodiment One, it includes a concrete filling 8 arranged between the processing side template 1 and the hollow slab beam inner mold 5.

Side channel steels 10 are arranged on both the left and right sides of the concrete filling 8. A transverse connecting screw 11 is threadedly connected to the opposite side of the two side channel steels 10.

[0033] By adopting the above technical solution, through the arrangement of the side channel steels 10 and the transverse fixing channel steels 12, it is convenient to support the concrete filler 8 after pouring is completed. By further arranging the transverse connecting screws 11, the two side channel steels 10 can be fixed, and at this time, it is convenient for the staff to carry out curing treatment on the surface of the concrete filler 8.

[0034] The working principle of the above embodiment is as follows:

[0035] First, the staff binds the transverse reinforcing steel bars 4 to the surface of the longitudinal reinforcing steel bars 3. At this time, the inner formwork 5 of the hollow slab beam is located inside the longitudinal reinforcing steel bars 3. Subsequently, the two processed side formworks 1 and the two processed cross formworks 2 are spliced. During the splicing process, the transverse reinforcing steel bars 4 are located between the two processed side formworks 1. Then, the two processed side formworks 1 and the processed cross formworks 2 are fixed by using the fixing bolts 7. After that, the concrete filler 8 can be poured between the two processed side formworks 1. After the concrete filler 8 is completely solidified, the processed side formworks 1 and the processed cross formworks 2 are removed, and the surface of the concrete filler 8 can be cured.
