The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] The high-level water tank in the high-level water tank assembly is supported by a support. Since the upper high-level water tank is a concrete pouring structure, the bottom surface of the high-level water tank is supported by a support (usually a steel support), and the structure is in a head-heavy foot-light form. Under various load working condition combinations, the horizontal force and vertical force at the connection between the support and the high-level water tank are large. In particular, in order to ensure that the steel support and the high-level water tank do not produce relative displacement in the horizontal direction and the connection is stable, in addition to relying on the friction resistance to resist sliding, structural measures should be strengthened to further ensure the stability of the structure and the safety of the force.

[0041] The utility model provides a kind of high-level water tank assembly and the connecting mechanism of high-level water tank and support, can make high-level water tank effectively resist horizontal force caused by earthquake and wind load, meet the use demand of horizontal load, guarantee the stability of water tank, in addition, it is convenient to construct, low in cost.

[0042] Please refer to Figures 1 to 5This application specification provides a connection mechanism between a high-level water tank and a support. The high-level water tank 100 is provided with a tank bottom plate 3 and a tank side wall 4 surrounding the tank bottom plate 3. The high-level water tank 100 is formed by concrete casting. The support has a support top surface, and the connection mechanism is disposed between the tank bottom plate 3 and the support top surface. A steel plate 1 is provided on the support top surface, and a plurality of steel beams 6 arranged in a crisscross pattern are fixedly connected to the lower surface of the steel plate 1. Specifically, the support can be a steel support 200.

[0043] The connection mechanism between the elevated water tank and the support includes a shear-resistant component, which includes multiple shear keys 2. The multiple shear keys 2 are fixed to the upper surface of the steel plate 1 and are integrally cast into the bottom plate 3 of the water tank. The multiple shear keys 2 are arranged at intervals along the longitudinal extension direction of the steel beam 6. The shear keys 2 have a embedment depth dimension along the height direction, and the embedment depth dimension is smaller than the thickness of the bottom plate 3 of the water tank.

[0044] In this embodiment, multiple shear keys 2 are spaced apart along the longitudinal extension direction of the steel beam 6 on the steel plate 1, and these shear keys 2 are fixed to the upper surface of the steel plate 1 and integrally cast into the bottom plate 3 of the water tank. After casting, the shear keys 2 and the concrete bottom plate of the elevated water tank 100 are integrally cast and become one unit. The horizontal force of the elevated water tank 100 is transmitted to the steel plate 1 through the shear keys 2, meeting the shear resistance (resistance to horizontal force) requirements of the shear keys 2 and the steel plate 1. This ensures that the shear keys 2 themselves will not be damaged by shear and tension, and also ensures the effective connection and force transmission between the shear keys 2 and the steel plate 1, playing a role in the overall structural stability. Ultimately, the elevated water tank 100 can effectively resist the horizontal force caused by earthquakes and wind loads, meeting the usage requirements of horizontal loads and ensuring the stability of the water tank. In addition, the connection mechanism between the elevated water tank and the support is easy to construct, low in cost, and has significant market application value.

[0045] like Figure 3 As shown, the shear key 2 and the upper surface of the steel plate 1 can be fixedly connected by welding. Specifically, a first weld portion 51 is formed between the shear key 2 and the upper surface of the steel plate 1. Further, the first weld portion 51 is a circumferential weld portion formed between the shear key 2 and the upper surface of the steel plate 1 by peripheral welding, thereby ensuring the reliability and strength of the weld. Specifically, the weld height of the circumferential weld portion includes any one of the following: 6 mm, 8 mm, 10 mm, and 12 mm. For example, when the weld height of the circumferential weld portion reaches 6 mm, the reliability and strength of the connection between the shear key 2 and the upper surface of the steel plate 1 can be reliably guaranteed.

[0046] In addition, the steel beam 6 and the steel plate 1 can be fixedly connected by welding, and specifically, the second welding portion 52 is formed between the steel beam 6 and the lower surface of the steel plate 1. Further, the second welding portion 52 is a circumferential welding portion formed between the steel beam 6 and the lower surface of the steel plate 1 by circumferential welding, so as to ensure the reliability and firmness of welding. Specifically, the weld height of the circumferential welding portion can be 8 mm. For example, when the weld height of the circumferential welding portion reaches 8 mm, the reliability and firmness of the connection between the steel beam 6 and the lower surface of the steel plate 1 can be reliably ensured.

[0047] When pouring, the shear key 2 is integrally poured with the water tank concrete bottom plate, the water tank horizontal force is transmitted to the first welding portion 51 through the shear key 2, the first welding portion 51 is transmitted to the steel plate 1, and the steel plate 1 is transmitted to the steel beam 6 through the second welding portion 52. When it is ensured that the shear key 2 itself has sufficient strength and is not easy to be pulled and sheared, the shear key 2 and the steel plate 1 are connected by a welding seam, and the size of the welding seam is set, so that the shear resistance (resistance to horizontal force) and tensile resistance (resistance to vertical pulling force) requirements of the shear key 2 and the steel plate 1 are met. In this way, it is ensured that the shear key 2 itself will not be damaged by shearing and pulling, and the effective connection and force transmission of the pull bar and the steel bottom plate are ensured, which plays a role in stabilizing the overall connection of the structure.

[0048] In the determination of the strength of the shear key 2 itself, it can be determined according to the following relationship:

[0049] Shear resistance of the shear key 2 itself: V≤fv×As×n;

[0050] Tensile resistance of the shear key 2 itself: V≤f×As×n;

[0051] V represents the shear design value at the shear key 2;

[0052] F represents the tensile strength design value;

[0053] Fv represents the shear strength design value;

[0054] As represents the cross-sectional area of the shear key 2;

[0055] n represents the number of cross sections of the shear key 2.

[0056] In addition, the stress condition of the weld formed at the first welding portion 51 can be determined by the following relationship:

[0057] Front fillet weld (force perpendicular to the length direction of the weld) N≤βf×he×Lw×ffw;

[0058] Side fillet weld (force parallel to the length direction of the weld) V≤he×Lw×ffw;

[0059] N represents axial tension or axial compression;

[0060] V represents shear force;

[0061] Lw represents weld length;

[0062] Ffw represents strength design value of weld;

[0063] He represents calculated thickness of weld;

[0064] Βf represents strength design value increase coefficient of fillet weld.

[0065] In the embodiment, the shear key 2 can be made of any one of the following: shear steel, square steel, I-beam, channel steel, round steel and round pipe. When the shear key 2 is made of the above materials, it is easy to construct and saves engineering materials. Of course, the raw materials for making the shear key 2 can also be other forms of small-diameter steel bars, and the raw materials for making the shear key 2 are not limited to the above description. Those skilled in the art can also make other changes under the inspiration of the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0066] In a specific embodiment, the shear key 2 can be made of H-shaped steel. For example, the shear key 2 can be made of H-shaped steel or square steel such as HW150x150x7x12, HW100x100x6x8, etc.

[0067] Specifically, the size of the H-shaped steel should not be too large (B and H should not exceed 200 mm), so as to ensure that the construction difficulty is small. Since the concrete bottom plate steel bars need to pass around the shear key 2, if the size of the steel bar is large, the number of steel bar bypass positions will increase, which will increase the construction difficulty.

[0068] In the embodiment, when a plurality of shear keys 2 are arranged at intervals along the longitudinal extension direction of the steel beam 6, the distance between the two adjacent shear keys 2 is between 200 mm and 600 mm.

[0069] When the distance between the two adjacent shear keys 2 can be controlled between 200 mm and 600 mm, specifically, the distance between the two adjacent shear keys 2 can be 300 mm, 400 mm or 500 mm. By arranging the shear keys 2 at equal intervals and arranging the main force components, the stress at the connection is more uniform, which conforms to the actual stress condition and avoids causing uneven stress and local connection failure.

[0070] Please refer to Figure 2 , Figure 3 In an embodiment, the steel beam 6 has a center symmetry plane: the projection of the shear key 2 towards the steel beam 6 is symmetrically arranged about the center symmetry plane.

[0071] In the embodiment, when the shear key 2 is symmetrically arranged about the center symmetry plane with respect to the projection of the steel beam 6, the force balance among the shear key 2, the first welding part 51, the steel plate 1, the second welding part 52 and the steel beam 6 can be achieved, and the horizontal and vertical forces can be counteracted, so that the high-level water tank 100 can effectively resist the horizontal force caused by the earthquake and wind load, and the use requirement of the horizontal load can be better met.

[0072] Please refer to Figure 4 and Figure 5 For example, the shear key 2 is an I-beam, the height of the shear key 2 is H, the width of the shear key 2 is B, the web thickness of the shear key 2 is tw, the flange thickness of the shear key 2 is t, and the length of the shear key 2 is L.

[0073] Since the shear key 2 is mainly used for horizontal shear, the length L (i.e., the embedding depth L of the shear key 2) of the shear key 2 is generally not less than 200 mm, for example, 200 mm or 250 mm can be preferred. The embedding depth L of the shear key 2 can ensure that the bearing capacity of the concrete when it is damaged is greater than the horizontal force borne by the column foot. Specifically, the embedding depth of the shear key 2 can be determined according to the following relationship:

[0074] L≥1.45V / (fc×B);

[0075] V represents the column foot shear force;

[0076] fc represents the design value of the axial compressive strength of the foundation concrete;

[0077] B represents the width of the shear key 2.

[0078] In addition, in order to ensure that the embedding depth of the shear key 2 does not affect the structure of the high-level water tank 100 itself, the embedding depth of the shear key 2 is less than the thickness of the water tank bottom plate 3.

[0079] The connection mechanism of the high-level water tank and the support provided in the embodiment can achieve effective connection of steel and concrete, and can achieve the effects of preventing the high-level water tank 100 from slipping under the action of the horizontal force and facilitating construction and saving design cost.

[0080] The embodiment of the application further provides a high-level water tank assembly, which comprises a high-level water tank 100, a support and the connection mechanism of the high-level water tank and the support. The high-level water tank assembly can achieve the technical effects achieved by the connection mechanism of the high-level water tank and the support, and specific descriptions are made in the above embodiment, which will not be repeated here.

In addition, in the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0082] The above various embodiments in the specification are described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0083] The above is only a few embodiments of the present application, although the embodiments disclosed by the present application are as above, but the content is only to facilitate the understanding of the present application and the adopted embodiment, not for limiting the present application.
