[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-2 As shown, this utility model provides a bridge pier mold for concrete pouring operations of bridge piers. The bridge pier mold includes an assembly section 1, a reinforcing component 2, and a tie rod assembly 3. Multiple assembly sections 1 are provided, and these sections 1 can be detachably assembled sequentially along the vertical direction. The cross-section of each assembly section 1 is rectangular and annular, and the multiple assembly sections 1 form a pouring cavity 100. The reinforcing component 2 includes multiple back ribs 21 spaced apart along the outer periphery of the assembly section 1, with the back ribs 21 abutting against the assembly section 1. The tie rod assembly 3 includes a tie rod 31, two pressing members 32, and two locking members 33. The tie rod 31 passes between two adjacent back ribs 21. The pressing members 32 and locking members 33 are both sleeved on the ends of the tie rod 31. The locking members 33 are configured to press the pressing members 32 against the back ribs 21. A pressing member 32 and a locking member 33 are respectively provided at both ends of the tie rod 31. Each end of the pull rod 31 is equipped with a pressing element 32 and a locking element 33.

[0033] The tie rod 31 and the locking member 33 work together to press the back rib 21 against the outer periphery of the assembly section 1 by the pressing member 32, thereby offsetting the lateral pressure of the concrete on the inner wall of the pouring cavity 100 during the concrete pouring operation, improving the overall stability of the pier mold, and having a simple structure, low production cost, and easy to use on-site materials.

[0034] It should be noted that the cross-sectional area of ​​the assembly section 1 in the horizontal direction can be determined according to the specific dimensions of the pier to be poured, and no specific limit is made here.

[0035] For example, in this embodiment, as the height increases, the cross-sectional area of ​​the pier to be poured gradually increases in the horizontal direction. Therefore, the cross-sectional area of ​​the assembly section 1 in the horizontal direction should also be adjusted accordingly to meet the operational requirements.

[0036] For example, in this embodiment, the pull rod 31 is specifically a precision-rolled threaded steel bar with a diameter of 20mm, and the locking member 33 is specifically a single nut structure adapted to the pull rod 31. The nut of the nut structure is 5cm long to ensure the connection strength between it and the pull rod 31.

[0037] Specifically, multiple reinforcing components 2 are spaced apart along the vertical direction. This arrangement ensures that the assembled sections 1 at different heights remain stable during the pouring process.

[0038] Specifically, a reinforcing component 2 is equipped with at least four back ribs 21 and at least four tie rod components 3. This arrangement makes the force distribution in the horizontal direction of the same assembly section 1 more balanced, further improving the stability of the pouring operation.

[0039] Specifically, the assembly section 1 includes multiple assembly segments 11 that are spliced ​​together horizontally. The arrangement of these assembly segments 11 facilitates the assembly and disassembly of the assembly section 1 and provides strong versatility.

[0040] For example, in this embodiment, the assembly segment 11 is configured as a steel plate with a thickness of at least 6 mm. In this embodiment, the thickness of the assembly segment 11 is 6 mm. In other embodiments, the thickness of the assembly segment 11 may be increased according to actual needs, and no specific limitation is made here.

[0041] More specifically, a connecting flange and / or connecting bolts are provided between two adjacent assembly sections 11. This arrangement increases the connection strength between adjacent assembly sections 11.

[0042] For example, in this embodiment, the connecting bolts are M20x65 bolts (8.8 grade), and the connecting flanges are 12×100mm flat steel.

[0043] Specifically, the pressure-blocking member 32 is V-shaped. This design saves materials while improving the stability and compressive strength of the pressure-blocking member 32.

[0044] For example, in this embodiment, the pressing member 32 is a commonly used angle steel or channel steel structure in the art, which will not be described in detail here.

[0045] More specifically, the locking element 33 is screwed onto the pull rod 31. With the above configuration, turning the locking element 33 will allow it to move along the pull rod 31, facilitating assembly and disassembly.

[0046] More specifically, the outer periphery of the assembly section 1 is provided with an anti-rust coating. The aforementioned anti-rust coating can prevent the assembly section 1 from being corroded during the concrete pouring and solidification process, thereby improving the durability of the assembly section 1.

[0047] For example, in this embodiment, the anti-rust coating is a commonly used anti-rust paint in the art, which will not be described in detail here.

[0048] Specifically, the pier mold also includes multiple vertical ribs, which are spaced apart along the outer periphery of the assembled section 1. The vertical ribs extend vertically and are positioned between adjacent assembled sections 1. The aforementioned vertical ribs prevent relative displacement of assembled sections 1 at different heights during concrete pouring and solidification, further ensuring the stability of the assembled section 1.

[0049] For example, in this embodiment, the vertical rib plate is a channel steel or angle steel structure commonly used in the art, which will not be described in detail here.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
