[0026] In order to make the person skilled in the art better understand the technical scheme of the utility model, the technical scheme of the utility model will be further explained in combination with specific embodiments below.

[0027] In combination Figures 1 to 6 As shown in the drawings, the embodiment is a water tank pull structure, which comprises a main pull structure 2 and an inclined pull structure 3. The main pull structure 2 comprises a first main pull 20, and the inclined pull structure 3 comprises a second main pull 30 and a plurality of inclined pulls. The first main pull 20 is arranged inside the water tank, and the two ends of the first main pull 20 are connected to the inner side of the wallboard 1 of the water tank. In the embodiment, the second main pull 30 and the plurality of inclined pulls are prefabricated as an integrated structure in the factory in advance, and the connection points of the plurality of inclined pulls on the second main pull 30 are staggered with each other. The second main pull 30 is connected in abutment with the first main pull 20 and can cooperate to form a closed cross section.

[0028] In some embodiments, as Figure 2 With Figure 3 As shown in the drawings, the main pull structure 2 further comprises a first positioning plate 21, and the inclined pull structure 3 further comprises a second positioning plate 35. The first main pull 20 is provided with the first positioning plate 21, and the second main pull 30 is provided with the second positioning plate 35 corresponding in position to the first positioning plate 21. The second positioning plate 35 is used for positioning the connection points of the inclined pulls. The welding position can be ensured to be the same as the design through the first positioning plate 21 and the second positioning plate 35, and the shear resistance of the connection can be enhanced by using the first positioning plate 21 and the second positioning plate 35.

[0029] Further, taking a commonly used inclined pull with a length of 500 mm and an included angle of 45° as an example, the theoretical intersection point of the inclined pull is at But due to the welding space, the connecting point of the diagonal tension bar needs to be staggered by a certain distance, so the first positioning plate 21 can be welded on the first main tension bar 20 at a position about 350mm away from the wall plate 1.

[0030] In some embodiments, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, four diagonal tension bars are used in the diagonal tension bar structure 3 in this embodiment, which are the upper diagonal tension bar 31, the lower diagonal tension bar 32, the left diagonal tension bar 33 and the right diagonal tension bar 34. The four diagonal tension bars are arranged in the upper, lower, left and right directions of the second main tension bar 30, and are not completely aligned with the center of gravity, thereby forming a "claw-shaped" structure to ensure that the tensile performance of the main tension bar structure 2 is fully utilized. Specifically, the upper diagonal tension bar 31 and the lower diagonal tension bar 32 are connected to the vertical side wall outside the second main tension bar 30, and the left diagonal tension bar 33 and the right diagonal tension bar 34 are connected to the horizontal side wall outside the second main tension bar 30.

[0031] Further, considering the stress working condition of the upper diagonal tension bar 31 in this embodiment, the upper diagonal tension bar 31 uses a steel strip, and the first main tension bar 20, the second main tension bar 30, the lower diagonal tension bar 32, the left diagonal tension bar 33 and the right diagonal tension bar 34 all use angle steel.

[0032] The implementation principle of the water tank tension bar structure of the embodiment is:

[0033] By prefabricating the second main tension bar 30 and the four diagonal tension bars into an integrated diagonal tension bar structure 3 in the factory, and then performing butt welding between the first main tension bar 20 in the main tension bar structure 2 and the second main tension bar 30 in the diagonal tension bar structure 3 on site, only two welds are needed to complete the fixed connection of the main tension bar structure 2 and the diagonal tension bar structure 3, reducing welding and minimizing the adverse effects of welding temperature stress on the main tension bar structure 2. At the same time, the first main tension bar 20 and the second main tension bar 30 are connected and matched to form a closed section, and the stress performance of the closed section is much better than that of the open section, which can improve the stress performance of the main tension bar structure 2 under complex stress state.

[0034] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
