[0026] As shown in FIGS. Figure 1 and Figure 2 A post-cast strip combined triangular steel pipe support structure, including a center steel pipe 1, the center steel pipe 1 outside is equipped with connecting piece 2, connecting steel pipe 3, adjusting piece 4 and locking rod 5. Connecting piece 2 is sleeved on the outside of center steel pipe 1, connecting steel pipe 3 is evenly distributed around the center steel pipe 1, and is movably connected with connecting piece 2, and the other end is movably connected with adjusting piece 4, and locking rod 5 is symmetrically and movably distributed on both sides of adjusting piece 4. The center steel pipe 1 is spliced by connecting piece 2, and the connecting piece 2 is provided with a groove 21 corresponding to the connecting steel pipe 3, and the groove 21 is provided with a bolt structure penetrating through itself and a section of the connecting steel pipe 3. The end of connecting steel pipe 3 close to groove 21 is arc-shaped, which can swing within a certain range in groove 21, and the other end is movably connected with adjusting piece 4 through bolt structure, and the two sides of adjusting piece 4 are fixedly connected with extension plate 41.

[0027] In this embodiment, both ends of the locking rod 5 are equipped with rotating grooves 51 that match the extension plates 41, allowing the extension plates 41 to be set through themselves and the frame steel pipes 6 of the locking rod 5, thereby enabling the extension plates 41 to swing left and right around the frame steel pipes 6, enhancing the flexibility and adaptability of the structure. The frame steel pipes 6 are externally sleeved with gaskets on both sides of the locking rod 5, and the bolt structures are all adjustable locking bolt structures, which not only ensure the stability of the structure but also allow for fine-tuning according to specific construction conditions to adapt to different gap widths and structural requirements. This design significantly improves the efficiency and economic benefits of post-cast strip construction while ensuring the safety and reliability of the structure, especially in the face of temperature changes and foundation settlement that cause structural stress changes, effectively dispersing and bearing these stresses, reducing the occurrence of cracks, and improving the overall stability and durability of the structure. As shown in the figure, both ends of the locking rod 5 are equipped with rotating grooves 51 that correspond to the extension plates 41, and the extension plates 41 are set through themselves and the frame steel pipes 6 of the locking rod 5, with the extension plates 41 swinging left and right around the frame steel pipes 6. The frame steel pipes 6 are externally sleeved with gaskets on both sides of the locking rod 5, and the bolt structures are all adjustable locking bolt structures to achieve the stability and adjustability of the structure.

[0028] It should be noted that the length of the locking rod 5 is determined according to specific installation and construction conditions, thereby ensuring that the adjusting steel pipe 2 adapts to the width of the crack and provides the best support effect, while the adjusting piece 4 adapts to the internal shape of the crack to ensure stable contact.

[0029] As shown in Figure 3 and Figure 4 , both ends of the locking rod 5 are equipped with rotating grooves 51 that correspond to the extension plates 41, and the extension plates 41 are set through themselves and the frame steel pipes 6 of the locking rod 5, with the extension plates 41 swinging left and right around the frame steel pipes 6. The frame steel pipes 6 are externally sleeved with gaskets on both sides of the locking rod 5, and the bolt structures are all adjustable locking bolt structures to achieve the stability and adjustability of the structure.

[0030] In this embodiment, the flexible rotation between the connecting steel pipe 3 and the adjusting piece 4 is realized through the cooperation of the rotating groove 51 on the locking rod 5 and the extension plate 41, which allows the support structure to adaptively deform slightly when facing the micro-variation and stress adjustment in the construction of the post-cast strip, thereby reducing the stress concentration inside the structure. The setting of the frame steel pipe 6 provides a solid peripheral support, and the gaskets outside can provide additional stability while protecting the locking rod 5 from wear. The adjustability of the bolt structure means that construction personnel can quickly adjust the tightness of the support structure according to the actual construction conditions and the width of the post-cast strip, ensuring the stability and safety of the structure. This design not only improves construction efficiency and reduces labor intensity, but also enhances the adaptability of the structure to environmental changes, especially when subjected to thermal stress caused by temperature changes and additional stress caused by foundation settlement, it can more effectively protect the integrity of the structure, reduce the occurrence of cracks, and prolong the service life of the structure.

[0031] In use, first place the center steel pipe 1 at the predetermined position, then set the connecting piece 2 outside the center steel pipe 1, ensure that the connecting piece 2 can be firmly fixed on the center steel pipe 1; then, the connecting steel pipe 3 is evenly wrapped around the center steel pipe 1 and is movably connected with the connecting piece 2, forming a basic frame of support, one end of the connecting steel pipe 3 is designed as a curved surface, so as to swing up and down in the groove 21, increasing the adaptability of the structure; then, the other end of the connecting steel pipe 3 is movably connected with the adjusting piece 4 through the bolt structure, the adjusting piece 4 is fixedly connected with the extension plate 41 on both sides, the extension plate 41 is provided with a rotating groove 51 for cooperation with the locking rod 5; the rotating grooves 51 at both ends of the locking rod 5 match the extension plate 41, so that the frame steel pipe 6 can penetrate the extension plate 41 and the locking rod 5, and allow the extension plate 41 to swing left and right with the frame steel pipe 6 as the center, the frame steel pipe 6 is sleeved with gaskets outside the locking rod 5, to enhance the stability of the structure; finally, through the adjustable locking bolt structure, the tightness of the support structure is adjusted according to the specific construction conditions and the width of the post-cast strip, to ensure the stability and safety of the structure, and the construction of the entire post-cast strip support structure is completed, so that it can effectively withstand the stress caused by temperature changes and foundation settlement, reduce the occurrence of cracks, and improve the stability and durability of the overall structure.

[0032] Although the utility model has disclosed as above with preferred embodiments, it is not intended to limit the utility model, and anyone skilled in the art can make various modifications and modifications without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model should be defined by the claims.
