[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Reference Figures 1 to 6This embodiment proposes a formwork structure for an irregularly shaped bridge pier tie beam, including a pair of first arc-shaped plates 1 spaced apart, and a plurality of second arc-shaped plates 2 spaced apart between the first arc-shaped plates 1. The first arc-shaped plates 1 and the second arc-shaped plates 2 are integrally connected by a plurality of first support templates 3, and two adjacent second arc-shaped plates 2 are integrally connected by second support templates 4. The first support templates 3 and the second support templates 4 are provided with a plurality of support components 5 for enhancing the stability of the first support templates 3 and the second support templates 4. The first arc-shaped plates 1, the second arc-shaped plates 2, the first support templates 3, and each of the second support templates 4 enclose a casting space for casting the bridge pier tie beam. A reinforcing cage (not shown in the figure) is provided in the casting space, which can be used to enhance the bonding force between concrete. By setting up a pair of first arc-shaped plates 1, and providing multiple second arc-shaped plates 2 between the pair of first arc-shaped plates 1, and by using first formwork 3 and second formwork 4 to integrally connect the first arc-shaped plates 1, the second arc-shaped plates 2, and two adjacent second arc-shaped plates 2, the aforementioned arc-shaped plates and formwork 4 enclose the pouring space for the pier tie beam, forming an integrated pouring formwork for the pier tie beam. This ensures that the poured pier tie beams are free from quality problems such as misalignment and cracks, resulting in a superior appearance and improved quality. The presence of a reinforcing cage in the pouring space enhances the bonding force between concrete sections, extending the service life of the pier tie beam. The installation of multiple support components 5 effectively fixes the first formwork 3 and the second formwork 4, ensuring continuous pouring.

[0033] Specifically, the spacing of the first template 3 is equal to the spacing of the second template 4, thus ensuring that the width of the cast tie beam is consistent.

[0034] Specifically, the support assembly 5 includes a first support rod 51, a second support rod 52, and a third support rod 53. The first support rod 51 is mounted on one side of the first formwork 3 or the second formwork 4, and the second support rod 52 is mounted on the other side of the first formwork 3 or the second formwork 4. The third support rod 53 connects the first support rod 51 and the second support rod 52. The first support rod 51, the second support rod 52, and the third support rod 53 combine to form a support frame. In this way, the support frame enhances the wind resistance and stability of the first formwork 3 and the second formwork 4, providing a guarantee for subsequent pouring.

[0035] Specifically, the first support rod 51, the second support rod 52, and the third support rod 53 are all steel structural components. This ensures that the first support rod 51, the second support rod 52, and the third support rod 53 have high strength, which in turn gives the first formwork 3 and the second formwork 4 high compressive strength.

[0036] Specifically, the axial direction of the third support rod 5 is perpendicular to the axial directions of the first support rod 51 and the second support rod 52, respectively. This perpendicular axial distribution facilitates rapid subsequent installation and ensures uniform force distribution at both ends of the third support rod 53. Of course, depending on the actual situation and specific needs, the axial directions of the first support rod 51 and the second support rod 52 can also be set at other angles to the axial direction of the third support rod 53; this is not a unique limitation.

[0037] Specifically, the irregularly shaped bridge pier tie beam formwork structure also includes a first stop block 6, which is used to install the third support rod 53 onto the first support rod 51. Specifically, the first support rod 51 has a first notch 510, and the third support rod 53 has a first fastener 8, which is used to push the first stop block 6 against the first support rod 51. When assembling the support frame is required, the third support rod 53 is passed through the first notch 510, and then the first stop block 6 is pushed by the first fastener 8 to fix the first support rod 51 in place. Because the first support rod 51 and the third support rod 53 are detachably connected, after the concrete pouring and curing period, the first support rod 51 and the third support rod 53 can be removed, which is simple, convenient, and facilitates subsequent reuse.

[0038] Specifically, the first fastener 8 is a fastening nut, and the third support rod 53 is provided with a fastening thread. After the third support rod 53 passes through the first notch 510, the third support rod 53 can be fixed to the first support rod 51 by tightening the fastening nut.

[0039] Specifically, the irregularly shaped pier tie beam formwork structure also includes a second stop block 7, which is used to install the third support rod 53 onto the second support rod 52. Specifically, the second support rod 52 has a second notch 520, and the third support rod 53 has a second fastener 9, which is used to push the second stop block 7 against the second support rod 52. When assembling the support frame, the third support rod 53 is passed through the second notch 520, and then the second fastener 9 pushes the second stop block 7 to fix the third support rod 53 in place. Because the second support rod 52 and the third support rod 53 are detachably connected, after the concrete pouring and curing period, the second support rod 52 and the third support rod 53 can be removed, which is simple, convenient, and facilitates subsequent reuse.

[0040] Specifically, the second fastener 9 is a fastening nut, and the third support rod 53 is provided with a fastening thread. After the third support rod 53 passes through the second notch 520, the third support rod 53 can be fixed to the second support rod 52 by tightening the fastening nut.

[0041] Specifically, the cross-sections of the first template 3 and the second template 4 are U-shaped.

[0042] Specifically, the outer walls of the first arc-shaped plate 1 and the second arc-shaped plate 2 are provided with a plurality of first reinforcing ribs 11 and a plurality of second reinforcing ribs 12, which are arranged in a vertically intersecting manner. By setting the first reinforcing ribs 11 and the second reinforcing ribs 12, the structural strength of the first arc-shaped plate 1 and the second arc-shaped plate 2 is enhanced, thereby improving the service life of the first arc-shaped plate 11 and the second arc-shaped plate 12.

[0043] Specifically, the outer walls of the first template 3 and the second template 4 are provided with multiple third reinforcing ribs, and the first support rod 51 and the second support rod 52 are respectively welded to the third reinforcing ribs. Through welding, the structural strength of the first template 3 and the second template 4 is ensured, and the bonding strength between the first support rod 51 and the second support rod 52 and the first template 3 and the second template 4 is enhanced.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
