Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and in particular to a modular steel structure system with sleeve flange connection. Background Technology

[0002] Currently, steel structures are structures made of steel materials and are one of the main types of building structures. Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing, making them suitable for outdoor use.

[0003] Traditional steel structure residential building construction involves a large amount of welding, which results in slow construction speed, serious environmental pollution, and difficulty in controlling the quality of welds, seriously affecting the safety performance of the building. Summary of the Invention

[0004] The purpose of this invention is to provide a modular steel structure system with sleeve flange connection to solve at least one of the aforementioned technical problems in the prior art. This application is a divisional application of patent application No. 2023111633914, filed on September 11, 2023, entitled "A Modular Steel Structure System with Sleeve Flange Connection and its Building".

[0005] To solve the above-mentioned technical problems, the present invention provides a modular steel structure system for sleeve flange connection, comprising: splicing unit, sleeve and connecting flange;

[0006] The splicing unit includes a crossbeam and a column;

[0007] The columns are erected vertically; the four columns are arranged in a rectangular pattern; the two ends of the crossbeam are connected to the two adjacent columns respectively, thus forming a frame-like splicing unit;

[0008] Both the upper and lower ends of the column are provided with insertion slots and connecting flanges.

[0009] When two adjacent splicing units are connected, the column of the upper splicing unit is connected to the column of the lower splicing unit, and a connection node is formed after being fixed by connecting flanges and bolts.

[0010] The upper and lower parts of the sleeve are respectively inserted into the insertion slots at the ends of the two columns that are joined together, and are used to resist shear when the steel structure is subjected to horizontal force.

[0011] During construction, the two ends of the sleeve are inserted into the insertion slots of the two columns on the upper and lower splicing units, and then the connecting flanges on the two columns are fixedly connected with bolts. This realizes the modularization and high standardization of the modular steel structure system. The assembly work is simple and efficient, achieving the goal of improving construction progress and reducing costs.

[0012] Furthermore, the insertion slot is provided with a limiting structure for limiting the insertion depth of the sleeve.

[0013] Furthermore, the limiting structure is an annular boss disposed within the insertion slot.

[0014] Furthermore, the column is a tube (such as a circular tube or a rectangular tube); the limiting structure includes threaded holes provided on the tube wall near both ends of the column, and screws adapted to the threaded holes; after the screw is screwed into the threaded hole, the top of the screw extends into the insertion groove, and the end face of the sleeve abuts against the screw.

[0015] Furthermore, in the height direction of the column, a plurality of threaded holes are spaced apart, and a screw can be selectively screwed into one of the threaded holes to accommodate sleeves of different lengths.

[0016] Furthermore, it includes several layers of frame structure, each layer of frame structure including one or more of the splicing units; the cross-sectional shape of the column is rectangular. More preferably, the cross-sectional shape of the column is square.

[0017] Furthermore, the connecting flange is an annular flange (rectangular or circular ring) continuously arranged around the circumference of the column.

[0018] In a single-level frame structure, only one column is included at a single connection node, and the ring flange is suitable for connecting two columns, one above the other.

[0019] Furthermore, the connecting flange is a U-shaped flange continuously arranged around the three adjacent sides of the column.

[0020] When a frame structure on the same floor includes two columns arranged side by side and adjacent to each other at a single connection node, U-shaped flanges are installed on the two columns, and the two U-shaped flanges can be spliced ​​together to form a rectangle.

[0021] Furthermore, the connecting flange is an L-shaped flange continuously arranged around two adjacent sides of the column.

[0022] When a frame structure on the same floor has 2-4 columns arranged side by side and adjacent to each other at a single connection node, an L-shaped flange can be used to connect the upper and lower sets of columns at that connection node.

[0023] In summary, different types of connecting flanges can be selected according to the different splicing methods of the splicing units, so as to complete the connection between the upper and lower sets of splicing units and avoid interference between the connecting flanges on the same layer.

[0024] Furthermore, the crossbeam is fixedly connected to the column via an I-shaped conversion component; the I-shaped conversion component includes an upper flange, a lower flange, and a middle web; the two ends of the upper flange, the lower flange, and the middle web are fixedly connected to the crossbeam and the column, respectively.

[0025] Furthermore, the I-shaped conversion component is provided with conversion end plates on one or both sides, and the I-shaped conversion component is fixedly connected to the crossbeam and / or column through the conversion end plates.

[0026] Furthermore, it also includes lifting components for lifting the splicing units; the lifting components are detachably and fixedly connected to the splicing units.

[0027] Furthermore, the lifting component includes a lifting flange and a lifting ring. The lifting flange is detachably and fixedly connected to the connecting flange on the splicing unit, and the lifting ring is fixedly connected to the lifting flange.

[0028] With the above-mentioned improved technical solution, when using lifting components to lift splicing units, the lifting flange is connected to the connecting flange of the splicing unit, and then the lifting flange and the connecting flange are fixed with bolts. Finally, the lifting ring and the lifting hook are attached. When the splicing unit is lifted to the expected position, the lifting hook and the lifting ring are separated, and then the bolts are turned to separate the lifting flange and the connecting flange, so as to lift the next splicing unit.

[0029] Furthermore, it also includes a connecting pad, which is a continuous closed ring. The connecting pad is set at the connection node and between the upper and lower sets of connection flanges. After the splicing units of the upper and lower layers are connected and fixed by passing multiple bolts through the connection holes on the connection flange and the connecting pad, the connecting pad connects all the bolts on the connection node in series.

[0030] The installation of connecting pads can connect and fix several splicing units on the same layer at the connection node, increasing the integrity and shear resistance of the entire steel structure.

[0031] Furthermore, in terms of height, the lowest layer of the splicing unit is connected to the foundation through an energy-dissipating structure;

[0032] The energy-consuming structure includes: an upper connecting pipe, an energy-consuming cylinder, and a lower connecting pipe;

[0033] The upper end of the upper connecting pipe is fixedly connected to the lower end of the column of the bottommost splicing unit by means of fixing flange, welding, etc.

[0034] The energy-consuming cylinder includes: an upper connector, a lower connector, and an energy-consuming plate;

[0035] The upper connector is used to connect to the lower end of the upper connecting pipe;

[0036] The lower connector is used to connect to the upper end of the lower connecting pipe;

[0037] The lower end of the lower connecting pipe is fixedly connected to the foundation;

[0038] The two ends of the energy-consuming plate are connected to the upper connector and the lower connector, respectively. When the upper connector and the lower connector are relatively displaced, the energy-consuming plate undergoes plastic deformation and consumes energy.

[0039] Preferably, the foundation is a pile cap, frame column, or ground beam; the lower connecting pipe is a steel pipe section vertically installed on the pile cap, frame column, or ground beam; or, the lower connecting pipe is a steel pipe pile.

[0040] Furthermore, the energy-consuming plate includes an upper connecting part, a middle energy-consuming part, and a lower connecting part, all integrally made of energy-consuming soft steel;

[0041] The upper connecting part is used to connect with the upper connecting member, and the lower connecting part is used to connect with the lower connecting member;

[0042] The intermediate energy-consuming section includes several spaced-apart energy-consuming soft steel strips, with both ends of the energy-consuming soft steel strips fixedly connected to the upper connecting section and the lower connecting section, respectively.

[0043] The second aspect of this application discloses a building employing the aforementioned sleeve-type flange connection modular steel structure system.

[0044] By adopting the above technical solution, the present invention has the following beneficial effects:

[0045] This invention provides a modular steel structure system and its building with sleeve flange connection. Multiple splicing units can be spliced ​​together as needed, resulting in diverse and flexible forms. When vertical splicing is required, the two ends of the sleeve are inserted into the insertion slots of the upper and lower splicing units respectively, and then the connecting flange is fixedly connected with bolts. This realizes the modularity and high standardization of the steel structure system, and the assembly work is simple and efficient, achieving the purpose of improving construction progress and reducing costs.

Detailed Implementation

[0068] The present invention will be further explained and described below with reference to specific embodiments.

[0069] Example 1

[0070] like Figure 1-3 As shown, this embodiment provides a modular steel structure system for sleeve-type flange connection, including: splicing unit 1, sleeve 2 and connecting flange 3;

[0071] The splicing unit 1 includes a crossbeam 1b and a column 1a; the column 1a is erected vertically; the four columns 1a are arranged in a rectangle; the two ends of the crossbeam 1b are respectively connected to the two adjacent columns 1a, thereby forming a frame-type splicing unit 1.

[0072] Both ends of the column 1a are provided with insertion slots 1c and connecting flanges 3. When two adjacent splicing units 1 are connected, the column 1a of the upper splicing unit 1 is connected to the column 1a of the lower splicing unit 1, and a connection node is formed after being fixed by the connecting flange 3 and bolts (not shown). The upper and lower parts of the sleeve 2 are respectively inserted into the insertion slots 1c at the ends of the two columns 1a that are connected, and are used to resist shear when the steel structure is subjected to horizontal force.

[0073] During construction, the two ends of the sleeve 2 are inserted into the insertion slots 1c of the two columns 1a on the upper and lower splicing units 1 respectively, and then the connecting flanges 3 on the two columns 1a are fixedly connected with bolts. This realizes the modularization and high standardization of the modular steel structure system. The assembly work is simple and efficient, achieving the goal of improving construction progress and reducing costs.

[0074] Preferably, the insertion groove 1c is provided with a limiting structure for limiting the insertion depth of the sleeve 2. The limiting structure may be an annular boss provided in the insertion groove 1c. Alternatively, the column 1a is a tube (such as a circular tube or a rectangular tube); the limiting structure includes threaded holes provided in the tube wall near both ends of the column 1a, and screws adapted to the threaded holes; after the screws are screwed into the threaded holes, the top of the screws extends into the insertion groove 1c, and the end face of the sleeve 2 abuts against the screws.

[0075] More preferably, in the height direction of the column 1a, a plurality of threaded holes are arranged at intervals, and a screw can be selectively screwed into one of the threaded holes to accommodate sleeves 2 of different lengths.

[0076] Preferably, this embodiment further includes a connecting pad 4, which is a continuous closed ring. The connecting pad 4 is located at the connection node and between the upper and lower sets of connecting flanges 3. After the splicing units 1 of the upper and lower layers are connected and fixed by multiple bolts passing through the connection holes on the connecting flanges 3 and the connecting pad 4, the connecting pad 4 connects all the bolts on the connection node in series. The connecting pad 4 can be made of metal materials with high connection strength such as steel. The setting of the connecting pad 4 can connect and fix several splicing units 1 on the same layer at the connection node, increasing the integrity and shear resistance of the entire steel structure.

[0077] The modular steel structure system includes several layers of frame structure, each layer of frame structure including one or more splicing units 1 arranged side by side; the cross-sectional shape of the column 1a is preferably rectangular. More preferably, the cross-sectional shape of the column 1a is square.

[0078] The connecting flange 3 can take various forms depending on the connection requirements. See also Figure 4 and 5 As shown, the connecting flange 3 can be an annular flange 3a (rectangular or circular ring) continuously arranged around the circumference of the column 1a. The same layer of frame structure includes only one column 1a at a single connection node, and the annular flange 3a is suitable for connecting two columns 1a, one above the other.

[0079] See Figure 2 , 6As shown in Figure 7, the connecting flange 3 can be a U-shaped flange 3b continuously arranged around the three adjacent sides of the column 1a. When the same layer of the frame structure includes two parallel and adjacent columns 1a at a single connection node, U-shaped flanges 3b are installed on the two columns 1a, and the two U-shaped flanges 3b can be spliced ​​together to form a rectangle. See also... Figure 8 As shown, the connecting pad 4 at the connection node and between the upper and lower U-shaped flanges 3b is a rectangular pad 4a.

[0080] See Figure 9 and 10 As shown, the connecting flange 3 can be an L-shaped flange 3c continuously arranged around two adjacent sides of the column 1a. When the same layer of the frame structure includes three columns 1a arranged side by side and adjacent to each other at a single connection node, the L-shaped flange 3c can be used to connect the upper and lower sets of columns 1a at that connection node. See also Figure 11 As shown, the connecting gasket 4 at the connection node and between the upper and lower sets of L-shaped flanges 3c is set as L-shaped gasket 4b.

[0081] In summary, depending on the splicing method of the splicing unit 1, different types of connecting flanges 3 can be selected to complete the connection between the upper and lower splicing units 1, so as to avoid interference between the connecting flanges 3 on the same layer.

[0082] Preferably, the crossbeam 1b can be fixedly connected to the column 1a via an I-beam conversion member 5; the I-beam conversion member 5 includes an upper flange, a lower flange, and a middle web; the two ends of the upper flange, lower flange, and middle web are respectively fixedly connected to the crossbeam 1b and the column 1a. See also Figure 12 As shown, optionally, the I-shaped conversion component 5 is provided with conversion end plates 5a on one or both sides, and the I-shaped conversion component 5 is fixedly connected to the crossbeam 1b and / or column 1a through the conversion end plates 5a.

[0083] See Figure 12 As shown, this embodiment also includes a lifting component 6 for lifting the splicing unit 1; the lifting component 6 is detachably and fixedly connected to the splicing unit 1. The lifting component 6 includes a lifting flange 6a and a lifting ring 6b. The lifting flange 6a is detachably and fixedly connected to the connecting flange 3 on the splicing unit 1, and the lifting ring 6b is fixedly connected to the lifting flange 6a.

[0084] With the improved technical solution described above, when using the lifting component 6 to lift the splicing unit 1, the movable lifting flange is connected to the connecting flange 3 of the splicing unit 1. Then, the lifting flange 6a is initially fixed to the flange with bolts. Finally, the lifting ring 6b is hooked to the hook. After the splicing unit 1 is lifted to the expected position, the hook is separated from the lifting ring 6b, and then the bolts are rotated to separate the lifting flange 6a from the connecting flange 3, thereby lifting the next splicing unit 1. Alternatively, the lifting component 6 may also include only the lifting ring 6b, with both ends of the lifting ring 6b passing through the through holes on the connecting flange 3 and threadedly connected to nuts.

[0085] This invention allows multiple splicing units 1 to be spliced ​​together as needed, resulting in diverse and flexible forms. When splicing is required between upper and lower sections, the two ends of the sleeve 2 are inserted into the insertion slots 1c of the upper and lower splicing units 1, and then the connecting flange 3 is fixed with bolts. This achieves modularization and high standardization of the steel structure system, making the assembly work simple and efficient, and achieving the goals of improving construction progress and reducing costs.

[0086] Example 2

[0087] This embodiment is basically the same as embodiment 1, except that:

[0088] See Figure 13 As shown, in terms of height, the bottommost splicing unit 1 is connected to the foundation via an energy-dissipating structure; the energy-dissipating structure includes: an upper connecting pipe 10, an energy-dissipating cylinder 600, and a lower connecting pipe 20; in this embodiment, the foundation is a ground beam structure, and the lower connecting pipe 20 is vertically installed at the connection point of two ground beams. The upper end of the upper connecting pipe 10 is fixedly connected to the lower end of the column 1a of the bottommost splicing unit 1 through a fixing flange, welding, or other means.

[0089] See Figure 14 and 15 As shown, the energy-consuming cylinder 600 includes: an upper connector 610, a lower connector 620, and an energy-consuming plate 630; the upper connector 610 is used to connect with the upper connecting pipe 10; the lower connector 620 is used to connect with the lower connecting pipe 20; the two ends of the energy-consuming plate 630 are respectively connected to the upper connector 610 and the lower connector 620. When the upper connecting pipe 10 and the lower connecting pipe 20 are relatively displaced, the energy-consuming plate 630 undergoes elastic deformation or plastic deformation to consume energy.

[0090] The energy-consuming plate 630 includes an upper connecting part 631, an intermediate energy-consuming part 632, and a lower connecting part 633, all integrally made of energy-consuming soft steel. The upper connecting part 631 is used to connect with the upper connecting member 610, and the lower connecting part 633 is used to connect with the lower connecting member 620. The intermediate energy-consuming part 632 includes a plurality of spaced-apart energy-consuming soft steel strips, the two ends of which are fixedly connected to the upper connecting part 631 and the lower connecting part 633, respectively.

[0091] The upper connector 610 is cross-shaped or star-shaped, including an upper web plate 611 arranged in a cross-shaped or star-shaped manner, and an upper wing plate 612 is vertically arranged at the end of the upper web plate 611; the upper connecting part 631 of the energy dissipation plate 630 is fixedly connected to the upper wing plate 612; the lower connector 620 is cross-shaped or star-shaped, including a lower web plate 621 arranged in a cross-shaped or star-shaped manner, and a lower wing plate 622 is vertically arranged at the end of the lower web plate 621; the lower connecting part 633 of the energy dissipation plate 630 is fixedly connected to the lower wing plate 622.

[0092] See Figure 16 As shown, this embodiment also includes a reset structure 640, which includes: an anchoring top plate 641 fixedly disposed on the upper connector 610, an anchoring bottom plate 644 fixedly disposed on the lower connector 620, and a reset spring 643.

[0093] In this embodiment, the energy dissipation cylinder 600 is a rectangular cylindrical body, and the reset structure 640 is symmetrically arranged in the front-back direction and the left-right direction of the energy dissipation cylinder 600; while when the energy dissipation cylinder 600 is a circle or a regular polygon, the reset structure 640 is evenly arranged in the circumference of the energy dissipation cylinder 600.

[0094] The return spring 643 rests against the anchoring top plate 641 and the anchoring bottom plate 644 at both ends. During operation or after installation, the return spring 643 is compressed, thus generating a preload force that tends to straighten the upper connecting member 610 and the upper connecting pipe 10. That is, when the upper connecting pipe 10 and the lower connecting pipe 20 experience relative displacement, the preload force of the return spring 643 in the return structure 640 can force the upper connecting member 610 and the upper connecting pipe 10 to return to their original positions.

[0095] When the upper connecting pipe 10 shifts or shakes under external force, the energy-dissipating plate 630 in the energy-dissipating cylinder 600 undergoes plastic deformation and dissipates energy, thereby eliminating the destructive effect of the external force on the upper connecting pipe 10. Simultaneously, the return spring 643, through its preload, straightens and resets the upper connecting pipe 10 and the splicing unit 1 above it, thus preventing damage to the building in natural disasters such as earthquakes, reducing the cost of restoring its functionality, and improving the functional recoverability of the closed-section steel column base. Preferably, the reset structure 640 is located on the outside of the energy-dissipating plate 630.

[0096] The return spring 643 is fixed by the screw 642 and the nut; the anchoring top plate 641 and the anchoring bottom plate 644 are respectively provided with through holes; the screw 642 is inserted into the two through holes, and the return spring 643 is fitted on the screw 642; the two ends of the screw 642 are connected and fixed to the anchoring top plate 641 and the anchoring bottom plate 644 by nuts.

[0097] By tightening the nuts at both ends of the screw 642, the distance between the anchoring top plate 641 and the anchoring bottom plate 644 can be adjusted, as can the preload of the return spring 643.

[0098] Optionally, the top anchor plate 641 is fixedly mounted on the upper connector 610 or the upper connecting pipe 10; the bottom anchor plate 644 is fixedly mounted on the lower connector 620 or the lower connecting pipe 20.

[0099] In this embodiment, the upper wing plate 612 can be connected and fixed to the upper connecting pipe 10 by bolts, riveting or welding; the lower wing plate 622 can be connected and fixed to the lower connecting pipe 20 by bolts, riveting or welding.

[0100] This embodiment achieves functional recoverability of closed-section steel columns without occupying building space or affecting their functionality, thus enabling efficient prefabricated construction of buildings. In terms of stress, it achieves both functional recoverability and energy dissipation, as well as good performance of rigid column bases under minor earthquakes.

[0101] Example 3

[0102] This embodiment is basically the same as embodiment 2, except that:

[0103] Reference Figure 17 As shown, this embodiment also includes an arc-shaped strip 651 made of energy-dissipating mild steel. The arc-shaped strip 651 has connecting holes at both ends. After being fitted onto the ends of the screw 642, the connecting holes at both ends of the arc-shaped strip 651 are tightened with nuts, thereby fixing the ends of the arc-shaped strip 651 to the anchoring top plate 641 and the anchoring bottom plate 644. One or more arc-shaped strips 651 can be selectively disposed on the outside of one or more return springs 643 to reinforce the partially or completely failed energy-dissipating plate 630 facing the return spring 643.

[0104] When some or all of the intermediate energy-consuming parts 632 in the energy-consuming plate 630 fail and cannot dissipate energy through normal plastic deformation, an arc-shaped strip 651 can be added to the outside of the failed intermediate energy-consuming part 632. The arc-shaped strip 651 is connected to both ends of the screw 642 facing the failed intermediate energy-consuming part 632 through the connecting holes. When the upper connecting pipe 10 and the splicing unit 1 are displaced relative to the lower connecting pipe 20, the arc-shaped strip 651 deforms accordingly and performs the function of dissipating energy.

[0105] More preferably, this embodiment may also include a groove-shaped limiter 652, which is a U-shaped channel steel with connecting holes at both ends. Anchoring top plate 641 and anchoring bottom plate 644 are inserted into the U-shaped groove of the groove-shaped limiter 652, and the connecting holes at both ends of the groove-shaped limiter 652 are fitted onto the two ends of the screw 642.

[0106] The U-shaped channel limiter 652 uses the width of the U-shaped channel to limit the maximum displacement between the upper connecting pipe 10 and the lower connecting pipe 20. It prevents excessive deformation of the column base from causing structural damage. During minor earthquakes, it only provides partial stiffness to the node. During moderate earthquakes, it limits the vertical deformation of the structure to prevent excessive deformation from affecting structural stiffness and comfort. During major earthquakes, it can not only limit the deformation at the node, but also dissipate energy to protect the main structure after significant deformation.

[0107] Example 4

[0108] This embodiment is basically the same as Embodiments 2-3, except that:

[0109] Reference Figure 18 As shown, this embodiment also includes a steel ball 670. A lower arc groove is provided at the top center of the lower web plate 621; an upper arc groove is provided at the bottom center of the upper web plate 611. The upper and lower arc grooves are arranged vertically opposite each other and spaced apart, thus forming a spherical space in which the steel ball 670 is rotatably embedded. The upper part of the steel ball 670 is inserted into the upper arc groove, and the lower part of the steel ball 670 is inserted into the lower arc groove. The steel ball 670 abuts against the lower web plate 621 and the upper web plate 611 respectively, thereby transmitting the supporting force from the lower connector 620 to the upper connector 610. The steel ball 670 is rotatably mounted. During an earthquake, when the upper connecting pipe 10 shakes, the steel ball 670 forms a hinge structure with the lower and upper arc grooves, allowing the upper connecting pipe 10 to swing freely. This enables the energy-dissipating plate 630 to begin dissipating energy. After the shaking ends, the upper connecting pipe 10 quickly returns to its original position under the preload of the return spring 643. Whether during energy dissipation or resetting, the steel ball 670 plays a crucial supporting role, significantly reducing the load on the energy-dissipating plate 630 and preventing the return spring 643 from being excessively compressed and failing. This ensures the normal energy dissipation and resetting efficiency of both, and greatly extends the service life of the energy-dissipating plate 630 and the return spring 643.

[0110] Example 5

[0111] This embodiment is basically the same as embodiment 4, except that:

[0112] Reference Figure 19 As shown, this embodiment includes: an upper hemisphere 671, a lower hemisphere 672, a steel pin 673, and a thrust disc spring 674; the upper hemisphere 671 and the lower hemisphere 672 are arranged vertically opposite each other and spaced apart; an upper shaft hole is provided at the center of the bottom surface of the upper hemisphere 671, and a lower shaft hole is provided at the center of the top surface of the lower hemisphere 672; the upper part of the steel pin 673 is slidably inserted into the upper shaft hole, and the lower part of the steel pin 673 is slidably inserted into the lower shaft hole; the upper hemisphere 671 and the lower hemisphere 672 can be arranged relatively close to or far apart through the steel pin 673; the thrust disc spring 674 is fitted on the steel pin 673 and is disposed between the upper hemisphere 671 and the lower hemisphere 672.

[0113] The lower web 621 has a lower arc groove at the top center; the upper web 611 has an upper arc groove at the bottom center; the upper and lower arc grooves are arranged opposite each other and spaced apart, the upper hemisphere 671 is inserted into the upper arc groove and the lower hemisphere 672 is inserted into the lower arc groove; when assembled or in operation, the thrust disc spring 674 is compressed, and the upper hemisphere 671 and the lower hemisphere 672 abut against the upper web 611 and the lower web 621 respectively under the spring force of the thrust disc spring 674, so as to realize the transmission of the supporting force from the lower connector 620 to the upper connector 610.

[0114] In Example 4, during long-term use or during a major earthquake, the column base structure undergoes significant deformation, causing large displacements or deflections in the upper connecting pipe 10 and the upper connecting piece 610. This can lead to the upper web plate 611 temporarily or for an extended period of time detaching from the steel ball 670, resulting in a sudden increase in the load on the energy dissipation plate 630 and the return spring 643. Consequently, the energy dissipation plate 630 and the return spring 643 may fail to function properly or even be damaged.

[0115] In this embodiment, the upper hemisphere 671 and lower hemisphere 672, under the spring force of the thrust disc spring 674, always abut against the upper web plate 611 and lower web plate 621. Even if the column base structure undergoes significant deformation, or the upper connecting pipe 10 and upper connecting member 610 experience large displacement or deflection, the upper hemisphere 671 and lower hemisphere 672, under the spring force of the thrust disc spring 674, will always abut against the lower web plate 621 and upper web plate 611, ensuring the smooth transmission of support force from the lower connecting member 620 to the upper connecting member 610. This prevents a sudden increase in load on the energy dissipation plate 630 and the return spring 643, which could cause them to malfunction or even be damaged.

[0116] To prevent the upper hemisphere 671 and the lower hemisphere 672 from tilting, one of the upper hemisphere 671 and the lower hemisphere 672 can be fixedly connected to the upper web plate 611 or the lower web plate 621 by welding.

[0117] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
