[0002] With the development of my country's road and bridge industry, bridge construction is spreading to areas with complex terrain, and the height of bridge piers is also increasing. Variable-section box piers are gaining popularity due to their advantages of rapid construction, economical and aesthetically pleasing appearance, lightweight construction, and stability. Traditionally, the reinforcement binding for variable-section box piers is typically done by erecting conventional scaffolding around the pier body, or by constructing simple temporary supports on the construction surface using steel pipes and fasteners as a construction platform. However, these existing construction methods have drawbacks.

[0003] Erecting conventional scaffolding around the pier body takes a significant amount of time, slowing down pier construction speed and limiting safety. As the pier height increases, the scaffolding's stability gradually decreases, raising safety concerns. The extensive use of scaffolding reduces the economic benefits of pier construction. Using steel pipes and fasteners to erect simple temporary supports on the construction surface requires repeated disassembly and assembly, and the pipes and fasteners are prone to wear and loss.

[0023] With reference to the accompanying drawings, the specific implementation is as follows:

[0024] A steel bar binding platform for box pier construction, such as Figure 3 As shown in the figure, the lashing platform is a rectangular lashing platform that can surround the pier body and is composed of four L-shaped lashing platforms connected to each other. Figure 1 As shown, each L-shaped lashing platform includes two groups of vertical support rods 1, and multiple vertical support rods 1 in the same group are arranged in sequence at intervals. The arrangement directions of the two groups of vertical support rods 1 are set at an angle to form an L-shaped corner arrangement structure. The multiple vertical support rods 1 are provided with one or more groups of horizontal support components at different heights on the side facing the outside of the L-shaped corner. The horizontal support components include multiple inner horizontal support rods 2 connected to the side facing the outside of the L-shaped corner of the vertical support rods 1. The multiple inner horizontal support rods 2 have the same height and are connected to form an L-shaped structure.

[0025] like Figure 1As shown, a plurality of transverse support rods 5 are connected to the inner horizontal support rod 2. The transverse support rods 5 are arranged horizontally and perpendicular to the inner horizontal support rod 2. The plurality of transverse support rods 5 are spaced apart along the length direction of the inner horizontal support rod 2. An oblique support rod 6 is connected between the end of the transverse support rod 5 away from the inner horizontal support rod 2 and the vertical support rod 1. The end of the transverse support rod 5 away from the inner horizontal support rod 2 is also connected to the outer horizontal support rod 3. The plurality of outer horizontal support rods 3 cooperate to form an L-shaped structure parallel to the inner horizontal support rod 2. A plurality of construction pedals 4 for people to step on are placed between the L-shaped structure of the inner horizontal support rod 2 and the L-shaped structure of the outer horizontal support rod 3.

[0026] In this embodiment, three sets of horizontal support components at different heights are provided on one side of the outer side of the L-shaped corner, so that workers can perform construction at three heights at the same time. Figure 2 and Figure 6 As shown, the outer horizontal support rod 3 is connected to a plurality of guardrail uprights 14, and the guardrail uprights 14 are matched with a plurality of guardrail crossbars 15 to form a guardrail to provide protection for construction workers. The top of the vertical support rod 1 is connected to a lifting hook 16 to facilitate the transportation of the L-shaped lashing platform.

[0027] like Figure 1 As shown, the bottom end of the vertical support rod 1 is provided with a universal wheel 10 for the four L-shaped lashing platforms to move and dock. The vertical support rod 1 is a channel steel, and the inner horizontal support rod 2 and the outer horizontal support rod 3 are angle steels. The bottom sides of the construction pedal 4 are respectively placed on the side where the inner horizontal support rod 2 and the outer horizontal support rod 3 are close to each other. Figure 6 As shown, a plurality of support steel bars 17 are welded to the bottom surface of the construction pedal 4. The length direction of the support steel bars 17 is parallel to the inner horizontal support rod 2 and the outer horizontal support rod 3. The plurality of support steel bars 17 are pressed onto the plurality of transverse support rods 5.

[0028] As shown in the figure, one end of the horizontal support assembly is provided with two docking sleeves 8, which are respectively mounted on the same end of the L-shaped structure formed by the inner horizontal support rod 2 and the outer horizontal support rod 3. The other end of the horizontal support assembly is provided with two docking links 9, which are respectively mounted on the other end of the L-shaped structure formed by the inner horizontal support rod 2 and the outer horizontal support rod 3. In this embodiment, the docking links 9 are made of angle steel.

During assembly, the four L-shaped lashing platforms are first divided into two groups, which are docked to form two U-shaped lashing platforms. The two U-shaped lashing platforms are then docked with each other to form a complete rectangular shape surrounding the pier body. The docking sleeve 8 is provided with connecting bolts, and the docking link 9 is provided with multiple bolt holes at intervals. The multiple bolt holes are arranged at intervals along the length direction of the docking link 9. When the connecting bolts of the docking sleeve 8 are inserted into different bolt holes on the docking link 9, the length of the docking link 9 extending into the docking sleeve 8 can be adjusted, thereby changing the overall size of the rectangular lashing platform, so that the lashing platform can be adjusted according to the size of the pier body to adapt to the construction of pier bodies with different cross-sectional sizes.

[0030] like Figure 2 、 4 As shown in Figure 6, a base steel plate 7 is provided at each end of the horizontal support assembly. The base steel plate 7 is connected to the bottom side of the transverse support rod 5. A telescopic device 11 is provided on the bottom side of one of the base steel plates 7, and a storage device 13 is provided on the bottom side of the other base steel plate 7. When two L-shaped lashing platforms are docked with each other, the telescopic rod 12 of the telescopic device 11 of one L-shaped lashing platform can be extended and inserted into the positioning hole of the storage device 13 of the corresponding height on the other L-shaped lashing platform. As shown in the figure, the telescopic device 11 is located on the side of the horizontal support assembly close to the docking link 9, and the storage device 13 is located on the side of the horizontal support assembly close to the docking sleeve 8. Two hydraulic cylinders are provided on the telescopic device 11, and blind holes corresponding to the piston rods of the two hydraulic cylinders are provided on the storage device 13.

[0031] When adjusting the size of the present invention, first place the assembled rectangular lashing platform, loosen the connecting bolts of the docking sleeve 8, then determine the telescopic length of the telescopic rod 12 according to the size of the pier body, use the controller to adjust the telescopic rod 12 for telescopic movement, and then adjust the spacing of the L-shaped lashing platform. After reaching the appropriate position, stop the movement of the telescopic rod 12, insert the connecting bolts of the docking sleeve 8 into the bolt holes corresponding to the new positions on the docking connecting rod 9, and finally select a construction pedal 4 of appropriate size for operation and lay it flat on the horizontal support assembly to form a complete construction surface, thereby completing the size adjustment of the lashing platform.

[0032] When dismantling the present invention, first adjust the position of the tied steel bars to avoid collision with the rectangular tying platform, then use the lifting hook 16 and the tower crane to smoothly lift the rectangular tying platform to the horizontal ground, remove the construction pedal 4, and move the L-shaped tying platform to a suitable position for maintenance and size inspection, waiting for construction again.
