Description

Technical Field

[0001] This utility model relates to the field of steel structure column base technology, specifically to shallow-buried steel structure rigid connection column base nodes and buildings. Background Technology

[0002] Steel column bases serve as the force-transfer link between steel columns and the foundation, transferring internal forces from the column base to the foundation and ensuring the stability of the main structure. Conventional steel column bases are divided into exposed and embedded types. Exposed column bases are shorter and easier to install, but they are usually higher than the finished building surface, which is detrimental to the building's aesthetics and requires regular maintenance. Embedded column bases have a more complex construction process, but provide direct and reliable force transfer, typically requiring a greater embedment height and thus a thicker foundation. This column base joint combines the characteristics of both exposed and embedded column bases, offering advantages such as short column base height, convenient installation, and reliable force transfer. Its easy installation and positioning can effectively shorten the construction period, and it requires a smaller foundation thickness, resulting in better economic efficiency. Utility Model Content

Set up column base installation grooves, and after the column base joints are installed, fill the grooves with concrete so that the column base joints are completely enclosed by the concrete foundation, connecting the steel column, the shallow-buried steel structure rigid column base joints, and the concrete foundation into a whole. The bending moment of the steel column is balanced by the embedded base plate structure and the concrete foundation reinforcement, greatly enhancing the bending resistance of the column base and reducing the number of anchor bolts; the shear resistance of the steel column section embedded in the concrete foundation is more direct and efficient.

[0025] 3. Three types of steel reinforcement connection sections and steel column connection methods are set to meet the usage conditions under different conditions, thus improving the versatility of this device.

[0026] 4. Grouting holes and grout outlet holes are provided on the central stiffening plate. The grouting holes are used to inject concrete into the column base, and the grout outlet holes are used to expel air from the column base.

[0027] 5. The distance between the upper surface of the lower embedded base plate and the surface of the lower embedded base plate is H2, where 0.3m ≤ H2 ≤ 0.5m.

[0041] Reference Figures 1-4 As shown, this utility model provides a shallow-buried steel structure rigid-connected column base node.

[0042] Example 1

[0043] It is applied to the connection between a concrete foundation 1 and a steel column 2; a column base installation groove 3 is reserved in the concrete foundation, and the concrete foundation reinforcement 14 is set in the poured concrete foundation and extends into the column base installation groove; the shallow-buried steel structure rigid connection column base node includes

[0044] Anchor bolt positioning frame structure 4 is embedded in the cast-in-place concrete foundation at the bottom of the column base installation groove, and several vertically arranged anchor bolts 4-1 are fixed inside the anchor bolt positioning frame structure. The anchor bolts extend from the cast-in-place concrete foundation into the column base installation groove.

[0045] Embedded base plate structure 5, the embedded base plate structure is placed in the column base installation groove and is fixedly connected to the anchor bolt; the bottom end of the steel column is fixedly connected to the embedded base plate structure;

[0046] The connecting section reinforcement 6 is used to fix and connect the steel column and the concrete foundation reinforcement located in the column base installation groove; wherein, the concrete foundation reinforcement and the connecting section reinforcement are connected by a threaded sleeve 11. Other reinforcement lap splicing methods can also be used.

[0047] A post-cast filling concrete layer is poured into the column base installation groove, connecting the steel column, the shallow-buried steel structure rigid column base node, and the concrete foundation into a whole.

[0048] In the aforementioned structure, column base mounting grooves are provided. After the column base joints are installed, concrete is filled into the mounting grooves, completely enclosing the column base joints within the concrete foundation. This connects the steel column, the shallow-buried steel structure rigid-connected column base joints, and the concrete foundation into a unified whole. The bending moment of the steel column is balanced by the embedded base plate structure and the concrete foundation reinforcement, significantly enhancing the bending resistance of the column base and reducing the number of anchor bolts. Furthermore, the shear resistance of the steel column section embedded in the concrete foundation is more direct and efficient.

[0049] Therefore, compared to exposed rigid column bases, this not only reduces size and improves the building's aesthetics but also significantly enhances the column base's durability. Furthermore, compared to embedded column bases, it eliminates the need for shear studs and ordinary reinforcing bars, requires less embedment depth, has a simpler structure, is easier to construct, and is more economical.

[0050] In addition, this column base joint can be prefabricated in the factory and then installed on site, which simplifies construction, facilitates transportation, and has a wider range of applications.

[0051] Example 2

[0052] Based on Embodiment 1, a preferred form of the embedded base plate structure is provided. The embedded base plate structure includes a lower embedded base plate 5-1, a middle stiffening plate 5-2, an upper embedded base plate 5-3, and a vertical stiffening plate 5-4; a leveling layer 7 is provided at the bottom of the lower embedded base plate, which is horizontally arranged in the column base mounting groove; the lower and upper embedded base plates are arranged in parallel and each has several sets of anchor bolt holes 5-5 for anchor bolts to pass through; the middle stiffening plate and the upper embedded base plate are located on the same horizontal plane, the middle stiffening plate is connected to the inner wall of the steel column, and the upper embedded base plate has a U-shaped structure and is connected to the outer wall of the steel column; several vertical stiffening plates are connected between the upper embedded base plate and the upper embedded base plate, and the vertical stiffening plates are fixedly connected to the outer wall of the steel column.

[0053] In the above embodiment, a leveling layer is provided at the bottom of the lower embedded part base plate to ensure that the bottom of the lower embedded part is in a horizontal installation state.

[0054] When a bending moment acts on a steel column, part of the moment is transferred to the foundation through the steel reinforcement connecting the column and the concrete foundation reinforcement. The other part is transferred to the concrete through the upper embedded base plate and anchor rods located around the steel column. During the transfer of the other part of the bending moment, a central stiffening plate is installed inside the steel column, and the central stiffening plate and the upper embedded base plate are located on the same horizontal plane. This ensures that when the bending moment acts on the steel column, the force on one side of the steel column is transferred to the opposite side by the central stiffening plate, ensuring that the force can be effectively transferred to the upper embedded base plate.

[0055] Since steel columns can be used in two forms depending on the requirements, one is a steel column and the other is a steel-concrete composite column; the difference between the two is that the latter is based on the former and concrete is poured into the column body as the column core. In order to facilitate the pouring of concrete into the steel column, grouting holes 12 and grout outlet holes 13 are provided on the middle stiffening plate. The grouting holes are used to pour concrete into the column base, and the grout outlet holes are used to expel air from the column base.

[0056] In the above embodiments, preferably, the distance between the upper surface of the upper embedded base plate and the upper surface of the concrete foundation is H1, where 0.3m ≤ H1 ≤ 0.5m. H1 mainly reserves space for the installation of the reinforcing bars and anchor bolt nuts of the concrete foundation surface layer; the distance between the upper surface of the lower embedded base plate and the surface of the lower embedded base plate is H2, where 0.3m ≤ H2 ≤ 0.5m, ensuring that the concentrated force of the steel column is effectively transferred to the concrete foundation, while improving the torsional resistance and stability of the steel column.

[0057] In the above embodiments, preferably, the thickness of the leveling layer is 30mm~70mm (50mm is used in the embodiment shown in the figure), and the leveling layer is made of M40 mortar; the post-poured filling concrete layer is made of C40 non-shrink fine aggregate concrete.

[0058] In the above embodiment, the anchor bolt positioning frame is determined by the construction unit, the anchor bolt diameter is determined by calculation, and the anchor bolt anchorage length is not less than 25 times the anchor bolt diameter. The anchorage length starts from the lower surface of the lower embedded part base plate. The anchor bolt holes provided on the lower and upper embedded part base plates are 1.2 to 1.5 times the diameter of the anchor rod, which facilitates the installation and adjustment between the anchor bolt and the embedded part base plate structure. Since the opening on the embedded part base plate is relatively large, an anchor bolt nut washer should be provided. After installation, the washer should be welded to the base plate and tightened with double nuts.

[0059] Example 3

[0060] Based on Examples 1 and 2, three preferred connection methods for steel reinforcement segments and steel columns are given.

[0061] The first type, such as Figure 5As shown, a number of through holes 8 are provided on the steel column for passing through the reinforcing bars. The reinforcing bar connection section passes through the prime number of through holes and overlaps with the concrete foundation reinforcement located in the column foot mounting groove. Concrete is poured inside the steel column, and the height of the concrete inside the steel column is higher than the reinforcing bar connection section.

[0062] The second type, such as Figure 6 As shown, several sleeves 9 are spaced apart around the steel column, and the sleeves are all located on the horizontal plane where the concrete foundation reinforcement is located; the steel bar connection section is fixedly connected between the sleeve and the concrete foundation reinforcement; the steel column is a steel column or a steel pipe concrete column.

[0063] The third type, such as Figure 7 As shown, several lap plates 10 are provided around the steel column, and the lap plates are located on the horizontal plane where the concrete foundation reinforcement is located; the steel bar connection section is fixedly connected between the lap plate and the concrete foundation reinforcement; the steel column is a steel column or a steel pipe concrete column.

[0064] In the above embodiments 1-3, the anchor bolt positioning frame structure includes a positioning frame 4-2 located in the concrete foundation at the bottom of the column base mounting groove, and several anchor bolts fixedly connected to the positioning frame.

[0065] The bending moment of the steel column (concrete-filled steel tube column) is balanced by the reinforcement of the concrete foundation surface. The axial pressure is diffused through the embedded base plate structure and borne by the concrete foundation. The shear force is transferred to the concrete foundation through the cross section of the steel column itself inserted into the concrete foundation as a shear key.

[0066] Compared to exposed column bases, this application replaces the tensile and compressive bending resistance of anchor bolts with the bending moment balance of the reinforced concrete foundation and embedded base plate structure, significantly enhancing the bending resistance of the column base and reducing the number of anchor bolts. Shear resistance is changed from relying solely on shear keys (anchor bolts cannot resist shear) to shear resistance from the steel column section embedded in the concrete foundation, which is more direct and efficient. Exposed rigid column bases are often too large, affecting the building's aesthetics and requiring secondary decoration; the column base node proposed in this invention only exposes the steel column itself, resulting in a more aesthetically pleasing design.

[0067] Compared to embedded rigid column bases, traditional embedded rigid joints require the steel column to be embedded in the concrete to a depth of not less than 2.5 times the side length of the steel column. This joint greatly reduces the embedment depth, saves materials, reduces the depth of earthwork excavation, and facilitates construction.

[0068] This utility model also provides a building, including the shallow-buried steel structure rigid column base node as described above.

[0069] The construction process of this utility model is as follows:

[0070] In step S10, steel columns and upper embedded base plates, lower embedded base plates, middle stiffening plates, vertical stiffening plates, etc. are prefabricated in the factory. The steel columns are welded to the lower embedded base plates, the upper embedded base plates are welded to the outer wall of the steel columns, the middle stiffening plates are welded to the inner wall of the steel columns, and the top, bottom, and sides of the vertical stiffening plates are welded to the upper embedded base plates, the lower embedded base plates, and the outer wall of the steel columns, respectively.

[0071] Step S20: Install anchor bolts and positioning frames before foundation pouring. Reserve column foot installation grooves on the concrete foundation on site. Pour the remaining foundation parts up to the top surface of the foundation.

[0072] Step S30: Install column base nodes, pour leveling layer (second pour), tighten anchor bolt nuts, and connect concrete foundation reinforcement to steel column through connecting section reinforcement; connection method can be lap plate, sleeve, or steel column with through hole and reinforcement directly anchored into column;

[0073] Step S40: Pour concrete into the rectangular steel pipe (this step can be omitted if steel columns are used), and pour the column base installation groove with micro-expansion non-shrinkage fine aggregate concrete of the same grade as the foundation.

[0074] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
