[0031] 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.

[0032] like Figures 1-3As shown, this embodiment provides a rebar tying platform for a precast bridge deck system, including a base 1, a first crossbar 2 arranged on the base 1, and several sets of supports 3 arranged above the first crossbar 2. In this embodiment, three bases 1 are arranged, and the bases 1 are made of I-beams. Positioning kits 4 are adjustablely arranged on the bases 1, and the positioning kits 4 are used to support movable pads 5 or to connect vertical supports 6. Vertical rods are also arranged on the bases 1 at the ends, and a first bent rod 7 is arranged at the top of each vertical rod, and a second crossbar 8 is arranged between two first bent rods 7.

[0033] In this embodiment, as Figures 1-4 The positioning kit 4 shown has an I-shaped outline and an internal slot 41 that matches the I-beam base 1. The bottom flange of the positioning kit 4 has positioning holes 42 for fixing the positioning kit 4 to the ground. Because the slot 41 in the positioning kit 4 matches the outline of the base 1, the positioning kit 4 can be moved to the desired position along the I-beam base 1 even when not fixed. Then, anchor rods or bolts are used to pass through the positioning holes 42 to fix the positioning kit 4 to the ground for rebar tying. Several corresponding fixing holes are pre-drilled at corresponding positions on the ground.

[0034] Furthermore, such as Figures 5-8 As shown, an auxiliary pad 9 can be optionally provided on the top of the positioning kit 4. The bottom of the auxiliary pad 9 has a groove 91 that matches the top of the positioning kit 4. The top of the auxiliary pad 9 has a protrusion 92 that matches the groove 91. Therefore, one auxiliary pad 9 can be placed on the top of the positioning kit 4 to support the moving pad 5. When the support height is still insufficient, two or more auxiliary pads 9 can be used to increase the height so as to support the moving pad 5 at a suitable height and facilitate the rebar binding operation.

[0035] The top of the positioning kit 4 located at one end of the base 1 is also fixed with a vertical support column 6. The vertical support column is made of vertically arranged I-beams and is used to provide lateral support or fixation for the edge reinforcement during the reinforcement binding operation.

[0036] In this embodiment, a fixing plate 10 is fixed on the base 1, and the fixing plate 10 is located next to the first crossbar 2; the bases 1 of two adjacent I-beams are also fixedly connected by a third crossbar 11.

[0037] The base 1 at the end has three first vertical bars 12 of the same height and one second vertical bar 13 lower than the first vertical bars 12. The tops of each first vertical bar 12 and second vertical bar 13 are connected by a first bent bar 7. Two first bent bars 7 are connected by a second horizontal bar 8. Two adjacent second horizontal bars 8 are connected by a right-angle bent bar 14. An L-shaped support bar 22 is fixed to the middle of each first vertical bar 12 on the same side. Two L-shaped support bars 22 are fixedly connected by two fourth horizontal bars 15. The tops of two L-shaped support bars 22 are connected by a fifth horizontal bar 16. Multiple sets of brackets 3 are arranged on the two fourth horizontal bars 15. The brackets 3 are arranged horizontally in a grid pattern. Adjacent brackets 3 are connected by a third vertical bar 17. The tops of the third vertical bars 17 connecting two adjacent brackets 3 are connected by a sixth horizontal bar 18. The brackets 3 are connected at the middle of the third vertical bars 17. The bottom of each third vertical bar 17 is fixed to a first horizontal bar 2. The third vertical bar 17, located at the edge, is connected to the adjacent first vertical bar 12 by a seventh horizontal bar 19; the sixth horizontal bar 18, the seventh horizontal bar 19, and one of the second horizontal bars 8 are connected by an eighth horizontal bar 20, which is perpendicular to the second horizontal bar 8. Each of the second horizontal bars 8 and the seventh horizontal bar 19 is also connected by a second bent bar 21.

[0038] The rebar tying platform for the precast bridge deck system provided in this embodiment uses multiple I-beams as the base 1, providing a stable support foundation for the entire platform. Positioning kits 4 are adjustablely arranged on the I-beam base 1. The slots 41 of the positioning kit 4's base are adapted to the I-beam base 1, allowing the positioning kit 4 to be moved to the required position according to the rebar tying needs. Anchor rods or bolts are then used to pass through the positioning holes 42 to fix the positioning kit 4 to the ground for rebar tying operations. The positioning kit 4 can support movable pads 5 and connect vertical supports 6, providing appropriate auxiliary support for the rebar tying operation of the precast bridge deck system. The movable pads 5 can support the rebars being tied, and the required number of auxiliary pads 9 can be added according to the height of the pads to meet the padding requirements. Figures 7-8 As shown, this platform is designed to accommodate the support needs of rebars at different heights during rebar tying operations. The positioning kit 4 can also be used to fix the vertical support column 6, which provides lateral support or fixation for edge rebars during rebar tying. Therefore, this platform can flexibly install pads or wooden blocks on the sides according to actual construction needs, solving the problem of the inability to support rebars on the sides in existing technologies.

[0039] The steel reinforcement binding platform for the precast bridge deck system provided in this embodiment forms an integral frame through the connection of multiple vertical bars on both sides, multiple bent bars at the top, and multiple horizontal bars; multiple sets of brackets 3 and various horizontal bars are used to connect and form a stable operating platform, while multiple bent bars and L-shaped support bars 22 and other structures enhance the overall stability of the platform.

[0040] The design of the positioning kit 4 and auxiliary pads 9 adapts to the needs of lateral support of reinforcing bars in different precast bridge deck construction scenarios. The positioning kit 4 can move along the base 1 of the I-beam, and after moving to the required position, it can be fixed to the ground for use. Furthermore, the height of the moving pad 5 can be flexibly adjusted by adding an appropriate number of auxiliary pads 9, allowing the platform to be quickly adjusted according to specific construction needs.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
