[0016] This application discloses a bridge pier formwork with an integrated design of an external ladder and a working platform. Multiple telescopic rods 51 are fixed to the ground by fixing nails 56 on the base 55, so that the multiple telescopic rods 51 support the outer formwork 10 and the top formwork 20 of the bridge pier, preventing tilting and loosening at the connection of the bridge pier formwork, and making the bridge pier formwork more stable.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please refer to Figure 1 This embodiment provides a bridge pier formwork with an integrated design of external ladder and working platform, including an outer pier formwork 10, a top pier formwork 20 on the top of the outer pier formwork 10, multiple working platforms 30 bolted to both sides of the outer pier formwork 10 and the top pier formwork 20, a staircase 40 in the middle of the multiple working platforms 30, and support mechanisms 50 on all four sides of the top pier formwork 20. Each support mechanism 50 includes telescopic rods 51, locking blocks 52, limiting blocks 53, springs 54, bases 55, fixing nails 56, and transverse support components 57. Adjacent telescopic rods 51 are interlocked, and the topmost telescopic rod 51 is hinged to the outside of the top pier formwork 20. The multiple telescopic rods 51... The length of the extension between them can be fixed. The base 55 is movably connected to the bottom end of the bottom telescopic rod 51. The base 55 is placed on the ground, and multiple fixing nails 56 are inserted through the base 55. The base 55 is fixed to the ground by the multiple fixing nails 56. The extension and contraction between the multiple telescopic rods 51 allows the base 55 on the bottom telescopic rod 51 to contact the ground. The fixing nails 56 on the base 55 are inserted into the ground, so that the base 55 and the telescopic rod 51 are fixed to the ground. The multiple telescopic rods 51 support the top template 20 of the pier at different angles on the four sides. When the top template 20 of the pier tends to tilt, the multiple telescopic rods 51 provide corrective support for the top template 20 of the pier, ensuring the overall stability of the top template 20 of the pier.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3The top of the telescopic rod 51 has a groove 511, and a locking block 52 is fixedly installed at the bottom of the telescopic rod 51. One locking block 52 at the top is slidably connected to the groove 511 of the bottom telescopic rod 51. A groove 521 is provided on one side of the locking block 52, and a limiting block 53 is slidably connected inside the groove 521. Limiting grooves 512 are provided at the top and bottom of one side of the telescopic rod 51, and the limiting block 53 passes through the inside of the limiting block 53. A spring 54 is installed inside the groove 521, and both ends of the spring 54 are fixedly connected to the limiting block 53 and the inner wall of the groove 521, respectively. The diameter of the locking block 52 is larger than the diameter of the telescopic rod 51 in which it is located, so that two adjacent The telescopic rods 51 will not separate. When the limiting block 53 moves to the position of the two limiting grooves 512, the elastic force of the spring 54 can drive the limiting block 53 to insert into the limiting groove 512, so that the extension length between the two adjacent telescopic rods 51 is fixed, so that the multiple telescopic rods 51 can be fixed to each other when supporting, ensuring the stability of the multiple telescopic rods 51 supporting the top template 20 of the pier. When the limiting block 53 is pressed, the limiting block 53 can retract into the groove 521, thereby releasing the fixation between the two telescopic rods 51, so that the multiple telescopic rods 51 can extend and retract, thereby retracting the multiple telescopic rods 51 into a smaller volume, which is convenient for carrying and installation.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 A transverse support assembly 57 is provided between multiple telescopic poles 51 and multiple working platforms 30. The transverse support assembly 57 includes a fixed pole 571 and a fixed rope 572. The fixed pole 571 is fixedly installed on the side of the working platform 30, and the fixed rope 572 is fixedly installed at one end of the fixed pole 571. One end of the fixed rope 572 is tied to the telescopic pole 51 on the same horizontal plane. By tying the two ends of the fixed rope 572 to the staircase 40 and the corresponding telescopic pole 51 respectively, the telescopic pole 51 and the staircase 40 become a whole. This allows the telescopic pole 51 to also support and limit the top template 20 of the pier and the working platform 30, thereby improving the overall stability.

[0021] The functional principle of this application can be explained through the following methods:

[0022] In use, each part of the outer formwork 10 of the pier is hoisted to the designated position, and then the top formwork 20 of the pier is hoisted to the top of the outer formwork 10 of the pier. Bolts are used to fix each part of the outer formwork 10 and the top formwork 20 of the pier. The working platform 30 is then bolted onto the outer formwork 10 and the top formwork 20 of the pier. The stairs 40 on the working platform 30 allow construction workers to work on the formwork at different heights. The limiting block 53 extending from the telescopic rod 51 is pressed down, and the telescopic rod 51 is pulled. The limiting block 53 retracts into the groove 521 under external force, allowing the telescopic rod 51 to be pulled out smoothly. The locking block 52 on the telescopic rod 51 is pulled to the outermost position of the slide 511, so that the limiting block 53, under the elastic action of the spring 54... The telescopic rod 51 extends into the limiting groove 512 on another telescopic rod 51, fixing the distance between two adjacent telescopic rods 51. Multiple telescopic rods 51 are extended so that the base 55 can contact the ground. Fixing nails 56 on the base 55 are inserted into the ground to fix the base 55, thus fixing multiple telescopic rods 51 to the ground. This allows multiple telescopic rods 51 to support the top template 20 of the pier at different angles. The fixing rope 572 at one end of the fixing rod 571 on the working platform 30 is tied to the corresponding telescopic rod 51, making the working platform 30 and the telescopic rod 51 a single unit. This allows the telescopic rod 51 to provide corrective tension to the outer template 10 of the pier and the working platform 30 when they tilt, ensuring the stability of the template.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
