Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically a building support structure. Background Technology

[0002] The traditional method for connecting steel lattice column inserts to the foundation involves directly using cup-shaped foundations or short columns with high cup-shaped foundations. Cup-shaped foundations are variable-section stepped foundations, while short columns with high cup-shaped foundations are short reinforced concrete columns with uniform cross-sections. This traditional method is suitable for foundations located below ground level with shallow excavation, but not for deep foundation pits where the steel lattice column inserts are buried at significant depths. Constructing long, uniform-section reinforced concrete columns to secure the inserts, or replacing the inserts with steel-framed columns encased in reinforced concrete extending down to the foundation surface, would result in considerable waste and increased construction difficulty.

[0003] In addition, when designing frame or truss steel structures with bridge cranes, the above-ground steel lattice columns are generally double-stage columns. The underground reinforced concrete columns that embed the steel lattice columns transform them from double-stage to triple-stage columns, increasing the difficulty of overall structural analysis and hindering rapid optimization and adjustment. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a building support structure that saves engineering costs, reduces the difficulty of overall structural analysis, and facilitates rapid optimization and adjustment of the structure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a building support structure, including a support body;

[0006] The support body includes a working section, an intermediate section, and a connecting section connected from top to bottom;

[0007] The longitudinal cross-sectional widths of the working section, the intermediate section, and the connecting section decrease sequentially, and the longitudinal cross-sectional structure of the intermediate section is an inverted T-shape.

[0008] As a further technical solution, a connector is also included, wherein the two frame columns at the lower part of the connector are respectively inserted into the two cup openings of the working section;

[0009] The bottom of the frame column is equipped with a leveling component, which controls the connector to be placed horizontally inside the cup opening.

[0010] As a further technical solution, the leveling component includes a sleeve, a screw, and a pad;

[0011] The top of the sleeve is fixed to the bottom end face of the frame column, the lower part of the sleeve is threaded to the upper part of the screw, the lower part of the screw is connected to the upper end face of the pad, and the lower end face of the pad abuts against the inner bottom wall of the cup opening.

[0012] As a further technical solution, the bottom end of the frame column is provided with a base plate, through which the frame column and the sleeve are connected.

[0013] As a further technical solution, the portion of the frame column exposed on the top surface of the support body is provided with a protective layer, and the height of the protective layer is 140-160mm.

[0014] As a further technical solution, at least three inverted U-shaped ribs are provided along the width direction of the working section, and the inverted U-shaped ribs are located between the two cup openings.

[0015] As a further technical solution, the top of the working section is provided with a first structural rib and a second structural rib, and the first structural rib and the second structural rib are horizontally arranged and form a mesh.

[0016] The first structural rib between the two cup openings is located inside the opening of the inverted U-shaped rib.

[0017] As a further technical solution, a gap is provided between the inner wall of the cup opening and the frame column, and the gap is filled with a filling material.

[0018] As a further technical solution, it also includes a base and a steel section, wherein the base is located at the bottom end of the support body, one end of the steel section is located in the support body, and the other end of the steel section is located inside the base.

[0019] The beneficial effects of this utility model are:

[0020] 1. The structural design of the working support body in this utility model ensures that its bottom cross section meets the lateral stiffness requirements of the support structure, and is suitable for use scenarios with large foundation depth. It also has the comprehensive advantages of reliable force bearing, convenient construction, good economy, and strong applicability.

[0021] 2. The combined design of the support body and the connector in this utility model makes the support structure suitable for a firm connection when the foundation is buried at a great depth. That is, the firmness and stability of the connector makes the structure of this utility model more widely applicable. In addition, the leveling part design at the bottom of the connector can, on the one hand, realize the quick connection between the connector and the support body and has a certain guiding function; on the other hand, the use of the leveling part can make the connector horizontally placed in the support body, so that the force is evenly distributed and further improves the stability of the overall structure.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0037] Example 1

[0038] See Figure 1 To improve the stability and load-bearing capacity of the structure when the foundation is buried at a great depth (e.g., 5-10 meters), and to facilitate structural analysis and on-site construction, this embodiment provides a building support structure, including a support body 1; the support body 1 includes a working section 11, an intermediate section 12, and a connecting section 13 connected sequentially from top to bottom;

[0039] The longitudinal section widths of the working section 11, the intermediate section 12, and the connecting section 13 decrease sequentially, and the longitudinal section structure of the intermediate section 12 is an inverted T-shape, such as the slope of the intermediate section 12 being 1:3 (i.e., width-to-height ratio). It should be noted that the width-to-height ratio at the section can be adjusted according to requirements, such as appearance requirements. The supporting body 1 of this structure meets the overall lateral stiffness requirements of the structure and also has a supporting function, such as bearing the weight and horizontal force of the building above.

[0040] For example, the supporting body 1 is a pier column, which can be formed by reinforcing steel formwork and then pouring concrete.

[0041] In the specific implementation process, see Figures 1-3This embodiment also includes a connector 2. The two frame columns 21 at the lower part of the connector 2 are respectively inserted into the two cup openings 111 of the working section 11. It should be noted that the longitudinal centerline of the connector 2 coincides with the longitudinal centerline of the support body 1. The upper part of the connector 2 is used to connect the building above ground. The gravity and horizontal force of the building are transmitted to the support body 1 through the connector 2, and then the gravity and horizontal force are distributed to the ground through the support body 1. For example, the connector 2 is a steel grating frame column structure.

[0042] The bottom of the frame column 21 is equipped with a leveling component 3. This leveling component 3 controls the connector 2 to be horizontally positioned within the cup opening 111. The leveling component 3 allows for quick connection between the connector 2 and the support body 1, preventing tilting. It also controls the insertion depth of the connector 2 into the support body 1, offering wider adaptability and improving construction speed and connection accuracy. For example, multiple leveling components 3 can be installed at the bottom of each frame column 21, with specific numbers determined according to requirements.

[0043] There is a gap between the inner wall of the cup mouth 111 and the frame column 21, and a filling material 4 is provided in the gap. The filling material 4 can be a non-shrink fine stone concrete or cement-based grout of a higher grade than that in the support body 1. An expansion admixture can be added to the filling material 4.

[0044] For example, the longitudinal section of the cup opening 111 is a frustum shape, and the depth of the cup opening 111 is greater than the depth of the connector 2 inserted into the support body 1, so as to meet the embedding requirements.

[0045] In the specific implementation process, see Figure 4 The leveling component 3 includes a sleeve 31, a screw 32, and a pad 33; the top of the sleeve 31 is fixed to the bottom end face of the frame column 21, the lower part of the sleeve 31 is threadedly connected to the upper part of the screw 32, the lower part of the screw 32 is connected to the upper end face of the pad 33, and the lower end face of the pad 33 abuts against the inner bottom wall of the cup mouth 111.

[0046] It can be noted that the lower part of the sleeve 31 is provided with an internal thread, while the upper part of the screw 32 has an external thread structure. The lower part of the sleeve 31 and the upper part of the screw 32 are connected by a thread to achieve a quick connection between the connector 2 and the support body 1. At the same time, the connector 2 can be placed flat in the support body 1, improving the stability of the overall structure.

[0047] For example, the cross-section of the frame column 21 is an I-beam. To improve anchorage, studs 22 are welded to the outer sides of both horizontal sides of the I-beam. For example, they can be spaced out along the length and height of the horizontal side. The outer edges of the top and bottom of the frame column 21 are 0.15m and 0.1m away from the inner wall of the cup opening 111, respectively.

[0048] The vertical distance between the outer edge of the top of the working section 11 and the outer edge of the top of the cup 111 shall not be less than 0.4m and shall meet the requirements for subsequent tie beam anchoring; the depth of the cup 111 shall be 0.2m greater than the depth to which the connector 2 is inserted into the support body 1;

[0049] Furthermore, the bottom end of the frame column 21 is provided with a base plate 23, which connects the frame column 21 and the sleeve 31. To facilitate venting and filling during the preparation process, the base plate 23 is provided with a vent hole 231. For example, the diameter of the vent hole 231 can be 80-100mm. The distance between the bottom end face of the base plate 23 and the inner bottom wall of the cup mouth 111 is 90-100mm. It should be noted that, depending on the requirements, a stiffening rib (not shown in the figure) can be provided at the bottom of the base plate 23. In this case, the position of the vent hole 231 should avoid the stiffening rib. For example, the stiffening rib is an inverted triangle set on the bottom end face of the base plate 23 to enhance the stability between the connector 2 and the support body 1.

[0050] In the specific implementation process, see Figure 1 The portion of the frame column 21 exposed at the top surface of the support body 1 is provided with a protective layer 5, and the height of the protective layer 5 is 140-160mm. It should be noted that the protective layer 5 can be used for corrosion protection of the frame column 21 at the ground level, and can also serve as an anti-collision device to prevent the frame column 21 at that location from being subjected to external impacts. The edge of the protective layer 5 is located between the outer edge of the cup rim 111 and the outer edge of the corresponding side of the frame column 21. For example, the distance between the outer edge of the protective layer 5 and the outer edge of the corresponding side of the frame column 21 can be 100mm.

[0051] For example, the protective layer 5 is made of low-strength concrete, and crack-resistant steel mesh is provided inside the protective layer 5. The spacing between adjacent steel bars in the crack-resistant steel mesh can be 150mm, and the spacing size can be selected according to actual needs. The horizontal bars in the mesh are closed into hoops.

[0052] In the specific implementation process, see Figures 1-3At least three inverted U-shaped ribs 6 are provided along the width direction of the working section 11, and the inverted U-shaped ribs 6 are located between the two cup openings 111 to improve the stability between the connector 2 and the support body 1. For example, the inverted U-shaped ribs 6 are evenly distributed along the width of the support body 1, and the bottom of the inverted U-shaped ribs 6 is located below the bottom end face of the cup opening 111.

[0053] Furthermore, the top of the working section 11 is provided with a first structural rib 14 and a second structural rib 15, and the first structural rib 14 and the second structural rib 15 are vertically arranged on the horizontal plane to form a mesh; in order to enhance the stability of the overall structure, the first structural rib 14 between the two cup mouths 111 is located inside the opening of the inverted U-shaped rib 6.

[0054] In the specific implementation process, see Figure 1 , Figure 5 This embodiment also includes a base 7 and a steel section 8. The base 7 is located at the bottom end of the support body 1, one end of the steel section 8 is located on the support body 1, and the other end of the steel section 8 is located inside the base 7.

[0055] It should be noted that the base 7 can be a structure made of concrete; the steel section 8 has an I-shaped cross-section, and a single row of studs is welded on the flange of the steel section 8 to improve the seismic performance of the overall structure and enhance the shear resistance of the bottom of the support body 1.

[0056] The construction steps of this utility model are as follows:

[0057] Step 1: Cast the foundation 7;

[0058] Step 2: Tie the reinforcing bars and support the body 1 mold, and reserve the cup mouth 111 in the shape of an inverted truncated pyramid, and reserve the position for the first structural reinforcement 14 of the protective layer 5. After acceptance, pour concrete into the support body 1 mold to form the support body 1.

[0059] Step 3: After the cup mouth 111 is formed and demolded, the upper surface of the cup mouth 111 is roughened using an electric roughening machine;

[0060] Step 4: Adjust the length of the leveling piece 3 in the longitudinal direction according to the design depth, so that the lengths of the two frame columns 21 are the same, and then insert the connector 2 with the leveling piece 3 into the cup opening 111.

[0061] Step 5: Use filler material 4 to fill the gap between the bottom plate 23 and the bottom of the cup mouth 111. After the frame column 21 is fixed and corrected, pour and fill the other gaps between the cup mouth 111 and the frame column 21 (i.e., the part above the bottom plate 23).

[0062] Step 6: Tie the horizontal rings in the protective layer 5, set up the mold of the protective layer 5 and pour the outer concrete.

[0063] Compared with the support structure in traditional buildings, the structure of this embodiment is suitable for scenarios with large foundation depths, and the connection between the connector and the support body is more robust. It can also meet the embedding requirements, facilitate quick optimization and adjustment of the building structure, and is convenient and economical to construct.

[0064] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
