[0005] To achieve the above objectives, this utility model provides the following technical solution: A precast platform for steel-concrete composite beam bridge deck includes a bottom mold, side molds fixedly installed at both ends of the bottom mold, movable end molds movably installed on both sides of the bottom mold, and reinforcement grooves spaced apart on the side walls of the movable end molds. Support seats and support frames are spaced apart at the bottom of the bottom mold, and reserved slots for installing reserved steel plates are spaced apart at the top of the bottom mold. End mold adjustment components connected to the movable end molds are movably installed at both ends of the support frame. An assembly component is fixedly installed on the top of the support seat, and auxiliary adjustment parts capable of adjusting the size of the reinforcement grooves are installed on the movable end molds.

[0006] As a further embodiment of this utility model, the auxiliary adjustment component includes a fixing plate, which is fixedly installed on the top of two sets of movable end molds on opposite sides. A lifting plate is provided on the top of the movable end mold, and a handle is fixedly installed at intervals on the top of the lifting plate. Movable grooves communicating with rib grooves are opened at intervals inside the movable end mold. Ribs are symmetrically arranged on both sides inside the movable grooves. An extrusion block is provided at the bottom of the inner side of the movable groove. A pull rod is fixedly installed on the top of the extrusion block, and the top of the pull rod slides through the movable end mold and the lifting plate to connect with each other.

[0007] As a further embodiment of this utility model, magnetic blocks are installed on both sides of the two sets of rib plates, and the corresponding magnetic blocks on the two sets of rib plates are attracted to each other by magnetic force, with the pull rod located between the two sets of magnetic blocks on the rib plates.

[0008] As a further embodiment of this utility model, the side wall of the fixing plate is provided with an adjustment groove spaced apart, the side wall of the lifting plate is provided with a positioning groove spaced apart, and the two sets of fixing plates are provided with a clamping plate on the side away from each other. The clamping plate is fixedly installed with a positioning plate that can be inserted into the adjustment groove and the positioning groove on the side close to the fixing plate.

[0009] As a further embodiment of this utility model, the assembly component includes a support plate, which is fixedly installed on a support base. A snap-fit ​​groove is provided on the top of the support plate, and an insert plate is provided on one side of the support plate. A movable rod is fixedly installed on the insert plate corresponding to the snap-fit ​​groove. A pull groove is provided in the support plate corresponding to the snap-fit ​​groove. A limit plate is fixedly installed on the movable rod corresponding to the middle position of the snap-fit ​​groove. An auxiliary groove is provided in the snap-fit ​​groove near the insert plate. A snap block is fixedly installed at the bottom of the bottom mold corresponding to the support base. A limit groove penetrating both sides of the snap block is provided on the side wall of the snap block, and a locking groove is provided at the middle position of the bottom of the snap block.

[0010] As a further embodiment of this utility model, the end mold adjustment assembly includes a movable block.

The reinforcement groove on the movable end mold can effectively and quickly carry out the reinforcement binding operation, thereby effectively saving the concrete pouring and curing time of traditional concrete platforms and greatly avoiding unnecessary waste of resources.

[0012] 2. In use, by raising or lowering the lifting plate, the lifting plate drives the extrusion block to rise or fall via the pull rod. When the extrusion block rises, it extrudes the two sets of reinforcing plates, causing them to move closer to the reinforcing groove, thereby reducing the width of the reinforcing groove. When the extrusion block falls, it does not extrude the two sets of reinforcing plates, and the two sets of reinforcing plates are attracted together by the adsorption magnet, causing the reinforcing plates to move into the movable groove, thereby expanding the width of the reinforcing groove. This effectively avoids the situation where the reinforcing bar diameter is too large, making it impossible to insert, or the reinforcing bar diameter is too small, causing grout overflow.

[0013] 3. When using this utility model, the bottom formwork can be disassembled through the assembly components, which facilitates the disassembly of the entire platform, making it easy to transport and move. This allows the platform to be reused in different areas and can also be adjusted on-site, greatly reducing the transportation cost of bridge deck panels. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 In this embodiment of the present invention, a prefabrication platform for steel plate concrete composite beam bridge deck includes a bottom mold 1, side molds 2 are fixedly installed at both ends of the bottom mold 1, movable end molds 3 are movably installed on both sides of the bottom mold 1, and rib grooves 10 are spaced apart on the side walls of the movable end molds 3. Support seats 4 and support frames 5 are spaced apart at the bottom of the bottom mold 1, and reserved grooves for installing reserved steel plates are spaced apart at the top of the bottom mold 1. End mold adjustment components connected to the movable end molds 3 are movably installed at both ends of the support frames 5. Assembly components are fixedly installed on the top of the support seats 4, and auxiliary adjustment parts capable of adjusting the size of the rib grooves 10 are installed on the movable end molds 3. The movable end mold 3 is adjusted by the end mold adjustment component, so that the two sets of movable end molds 3 on the bottom mold 1 are firmly fixed. At this time, the steel bars that need to be tied are arranged and tied through the bar grooves 10 on the movable end mold 3. After the tying is completed, concrete pouring is carried out. After the panel is formed, the movable end mold 3 is adjusted by the end mold adjustment component, so that the demolding operation can be completed.

[0024] The bottom mold 1 can be fixed and disassembled by the assembly components on the support base 4.

[0025] The size of the reinforcing bar groove 10 can be adjusted by the auxiliary adjustment component, so that the size of the reinforcing bar groove 10 can be adapted to the size of the reinforcing bar. This can effectively avoid the reinforcing bar diameter being too large to be inserted, or the reinforcing bar diameter being too small to cause grout overflow.

[0026] The auxiliary components include a fixing plate 6, which is fixedly installed on the top of two sets of movable end molds 3 on opposite sides. A lifting plate 7 is provided on the top of the movable end mold 3, and a handle 8 is fixedly installed on the top of the lifting plate 7 at intervals. Movable grooves 11 are provided inside the movable end mold 3 at intervals. The movable grooves 11 penetrate the movable end mold 3 and are interconnected with the rib grooves 10. Ribs 12 are symmetrically arranged on both sides inside the movable grooves 11. The two sets of ribs 12 are arc-shaped blocks that are close to each other on one side. A pressing block 14 is provided at the bottom of the inner side of the movable groove 11. The pressing block 14 is located between the two sets of ribs 12. A pull rod 13 is fixedly installed on the top of the pressing block 14. The top of the pull rod 13 slides through the movable end mold 3 and is interconnected with the lifting plate 7. Adsorption magnetic blocks 15 are installed on both sides of the two sets of ribs 12, and the corresponding adsorption magnetic blocks 15 on the two sets of ribs 12 are magnetically attracted to each other. The pull rod 13 is located between the two sets of adsorption magnetic blocks 15 on the ribs 12.

[0027] By raising the handle 8, the lifting plate 7 is raised on the movable end mold 3. The rising of the extrusion block 14 causes the two sets of ribs 12 to be squeezed and move away from each other, thereby reducing the width of the rib groove 10. Conversely, when the extrusion block 14 descends, it does not squeeze the two sets of ribs 12. However, the magnetic attraction of the magnetic blocks 15 on the two sets of ribs 12 causes them to move closer together, thereby increasing the width of the rib groove 10. The pull rod 13 is set between the two sets of magnetic blocks 15 on the same side, which can effectively prevent the pull rod 13 from hindering or interfering with the magnetic force of the magnetic blocks 15. The side wall of the fixed plate 6 is provided with an adjustment groove 32 at intervals. The adjustment groove 32 is arranged side by side along the length and height of the fixed plate 6. The side wall of the lifting plate 7 is provided with a positioning groove 30 at intervals. The size of the positioning groove 30 is adapted to the size of the adjustment groove 32. The two sets of fixed plates 6 are provided with a retaining plate 9 on the side away from each other. The retaining plate 9 is fixedly installed with a positioning plate 31 that can be inserted into the adjustment groove 32 and the positioning groove 30 on the side close to the fixed plate 6.

[0028] By using the clamping plate 9 and the positioning plate 31 on the clamping plate 9, after the lifting plate 7 is adjusted to the designated position, the adjusting groove 32 at the corresponding position on the fixing plate 6 is inserted into and extends into the positioning groove 30 on the lifting plate 7, thereby completing the positioning limitation of the height of the lifting plate 7.

[0029] The assembly includes a support plate 16, which is fixedly mounted on a support base 4. A slot 18 is formed on the top of the support plate 16, and an insert plate 17 is provided on one side of the support plate 16. A movable rod 20 is fixedly installed on the insert plate 17 corresponding to the slot 18. A pull groove 25 is formed inside the support plate 16 corresponding to the slot 18, allowing the movable rod 20 to be inserted into the slot 18 and moved for adjustment. A limiting plate 19, which is disc-shaped, is fixedly installed on the movable rod 20 at the middle position inside the slot 18. The limiting plate 19 is located near the insert plate 18. 7. An auxiliary groove 24 is provided at one end. The width and thickness of the auxiliary groove 24 are adapted to the outer diameter and thickness of the limiting plate 19. A buckle 21 is fixedly installed at the bottom of the bottom mold 1 corresponding to the position of the support base 4. The size of the buckle 21 is adapted to the size of the buckle groove 18. A limiting groove 22 is provided on the side wall of the buckle 21, which runs through both sides of the buckle 21. The width and thickness of the limiting groove 22 are adapted to the width and thickness of the limiting plate 19. A slot 23 is provided at the middle position of the bottom of the buckle 21. The width of the slot 23 is adapted to the outer diameter of the movable rod 20.

[0030] By installing the buckle 21 on the bottom mold 1 onto the movable rod 20 in the buckle groove 18 via the slot 23, the insert plate 17 is pushed, causing the limit plate 19 to move from the auxiliary groove 24 into the upper limit groove 22 of the buckle 21 via the movable rod 20, thereby completing the fixed support of the bottom mold 1. When the insert plate 17 is pulled, the insert plate 17 will move the limit plate 19 out of the limit groove 22 on the buckle 21 and into the auxiliary groove 24 via the movable rod 20. At this time, the buckle 21 is no longer restricted by the limit plate 19, thus enabling the bottom mold 1 to be disassembled from the support base 4.

[0031] The end mold adjustment assembly includes a movable block 26. The top of the movable block 26 is fixedly mounted with a support rod 27 that is connected to the movable end mold 3. The movable block 26 is located at both ends of the support frame 5. The two ends of the support frame 5 are fixedly mounted with screws 28. The screws 28 slide through the side wall of the movable block 26 and extend to the end of the movable block 26 away from the support frame 5. The side wall of the screws 28 is provided with threads, and a nut 29 is threaded on the screws 28. By tightening the nut 29, the nut 29 will push the movable block 26 to move closer to the support frame 5 until it can no longer move. At this time, the support rod 27 will drive the movable end mold 3 to move on the bottom mold 1, so that it moves to the designated position. The support rod 27 can support the movable end mold 3 and prevent the movable end mold 3 from deforming due to the lateral pressure of the concrete.

[0032] The working principle of this utility model is as follows: In use, the bottom mold 1 is installed on the support base 4 via the assembly components on the support base 4, and is supported and fixed by multiple sets of support bases 4. Adjustment is made by turning the push nut 29, causing the movable block 26 to move and fix the movable end mold 3 in the designated position. Then, according to the operational requirements, the bottom mold 1 is... Positioning plate 31 is moved out of the positioning position by clamping plate 9 30 slot and adjusting groove 32At this point, after raising or lowering the lifting plate 7 to the designated position, the positioning plate 31 is inserted again into the adjusting groove 32 on the fixing plate 6 and the positioning groove 30 on the lifting plate 7 via the clamping plate 9. During this process, when the lifting plate 7 drives the pull rod 13 to rise, the pressing block 14 will press the two sets of rib plates 12, thereby reducing the width of the rib groove 10. When the lifting plate 7 drives the pull rod 13 to fall, the pressing block 14 will not press the two sets of rib plates 12. The two sets of rib plates 12 are attracted by the magnetic force of the adsorption magnetic block 15 on them and move towards the pull rod 13. When the reinforcement is moved closer, the width of the groove 10 will increase, allowing for adjustment of the reinforcing bars according to actual needs. After the reinforcing bars are tied and the pouring is completed, direct curing can be carried out on the bottom formwork 1. When demolding is required, the nut 29 is rotated in the opposite direction to create a gap between the nut 29 and the movable block 26. Then, by pushing the movable block 26 closer to the support frame 5, the movable block 26 moves on the screw 28, thereby separating the movable end formwork 3 from the panel, thus completing the demolding operation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
