Traditional prefabrication platforms often use concrete structures, requiring large sites, fixed platform locations, and significant investment. Furthermore, traditional prefabrication platforms are prone to cracking and difficult to repair. For example, traditional concrete prefabrication platforms are prone to cracking during the hardening process, affecting their durability and stability. Moreover, when concrete prefabrication platforms are damaged or require repair, the repair process is complex and time-consuming. Utility Model Content

[0046] This utility model embodiment at least alleviates the technical problems existing in the prior art, such as the tendency of precast concrete platforms to crack, the difficulty of repair, and the long construction period.

[0047] In this embodiment of the invention, the supporting mold structure 1 has a space for pouring concrete, preferably a cuboid structure, and a reinforcing steel structure 4 is provided within this space. This reinforcing steel structure 4 can be a mesh structure. During use, concrete is poured into the space, and after the concrete dries, it connects with the reinforcing steel structure 4 to form a reinforced concrete bridge deck. Finally, the reinforced concrete bridge deck is removed from the supporting mold structure 1. When bridge decks of different cross-sectional sizes need to be prefabricated, simple disassembly and repetition of the above operations are sufficient for prefabrication.

[0048] Compared with the prior art, the combined precast bridge deck template provided by this utility model, by setting a grid-like steel reinforcement structure 4 in the supporting mold structure 1, so that after concrete is poured into the accommodating space and dried, a reinforced concrete bridge deck is formed.

[0052] Specifically: the side comb plate 5 is provided with a first groove 51 along the vertical direction, and multiple first grooves 51 are distributed at certain density intervals. Each first groove 51 is connected to the relevant components of the steel reinforcement structure 4 so that the steel reinforcement structure 4 is positioned in the same way for the support mold structure 1, thereby making each concrete bridge panel 3 made by the combined precast bridge panel template provided in this embodiment the same specification.

[0053] Furthermore, referring to Figure 1 The side comb plate 5 is provided with a plurality of reinforcing ribs 52 at intervals along its extension direction, and the plurality of reinforcing ribs 52 are all arranged along the first direction.

Each vertical rib 41 is distributed at a 90-degree angle to the horizontal rib 42. The two intersect each other to form a mesh structure and are connected at the intersection by fasteners 43, which can be metal wires, etc.

[0059] In an optional implementation of this embodiment, refer to Figure 2 , Figure 6 and Figure 7 The precast bridge deck template also includes a reserved plug structure 2, which is located within the accommodating space and is used to separate the concrete to reserve slots for later construction.

At this time, due to the function of the reserved plug-in structure 2, the insertion position will not be filled with concrete. After the concrete dries, the reserved plug-in structure 2 will be removed to create through holes 31.

[0061] Furthermore, referring to Figure 4 The reserved plug-in structure 2 includes a plug-in 21 and a fixing component 22. The plug-in 21 is plugged into the steel reinforcement structure 4.

[0063] Furthermore, referring to Figure 4 and Figure 6 The plug-in 21 has a second groove 212, which is plugged into the steel structure 4; the plug-in 21 is equipped with a lifting beam 211.

[0064] Specifically, the side wall of the plug-in 21 has a second groove 212, and the second grooves 212 are spaced apart, with the spacing matching the spacing of the support ribs. This allows the second grooves 212 of the plug-in 21 to connect with the corresponding support ribs when it is inserted into the support mold structure 1, thereby positioning the plug-in 21. A lifting beam 211 is provided at the top of the plug-in 21 for easy placement and retrieval by the user.

[0065] Furthermore, referring to Figure 4 The fixing component 22 includes a connector 221, a first fixing component 222 and a second fixing component 223. One end of the connector 221 is connected to the plug-in 21 through the first fixing component 222, and the other end is connected to the supporting mold structure 1 through the second fixing component 223.

[0066] Specifically: both the first fixing member 222 and the second fixing member 223 can be nuts. Correspondingly, the connecting member 221 is a connecting rod with threads at both ends. One end of the connecting member 221 passes through the insert 21 and the bottom template 12 in sequence and is fixed by the second fixing member 223. A gasket can be set between the second fixing member 223 and the bottom template 12. The other end of the connecting member 221 is provided with the first fixing member 222. The first fixing member 222 abuts against the top of the insert 21. That is, the connecting member 221 is fixed relative to the insert 21 and the bottom template 12 by the first fixing member 222 and the second fixing member 223, so that the insert 21 is fixedly connected to the bottom template 12.
