[0002] In recent years, steel structure buildings have become increasingly popular due to their short construction time and good earthquake resistance. The connection between beams and columns plays a vital role in the overall stability, strength and solidity of steel structures. In particular, although the connection columns of circular hollow sections have excellent buckling resistance and aesthetics, due to the curved surface design, the connection columns of circular hollow sections often require more complex connection designs than the connection columns of H-section and rectangular hollow sections.

[0003] At present, the two main types of connections in steel structures are welding and bolting. In terms of assembly, welded connections have high strength and rigidity, but on-site welding requires skilled welding technology; while bolted connections, in which bolts are manufactured off-site and assembled on-site by bolts, usually require multiple bolts to connect and fix each beam and column, which takes a lot of time and leads to low installation efficiency. In terms of disassembly, welded connections are difficult to disassemble and usually require time-consuming cutting, which damages structural components and makes steel components unreusable; and the time taken to dismantle the bolted beam-column connection structure is three times the time taken to cut the welded beam-column connection structure, which seriously wastes time and leads to low disassembly efficiency. Summary of the invention

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Please also read Figures 1 to 3 The recyclable assembled beam-column connection structure provided in the embodiment of the present application is now described. The recyclable assembled beam-column connection structure comprises: a connection column 10, a cross beam 20 and a connection sleeve 30.

[0039] A first connecting portion 11 is provided on the circumferential side surface of the connecting column 10; a second connecting portion 21 is provided at the end of the crossbeam 20; a connecting sleeve 30 is sleeved on the connecting column 10, and a third connecting portion 31 is provided on the inner side surface of the connecting sleeve 30, and the third connecting portion 31 is detachably engaged with the first connecting portion 11, and a fourth connecting portion 32 is provided on the outer side surface of the connecting sleeve 30, and the fourth connecting portion 32 is detachably engaged with the second connecting portion 21.

[0040] For example, Figures 1 to 3 As shown, the first connecting portion 11 on the connecting column 10 is arranged at a preset installation position of the connecting sleeve 30, the second connecting portion 21 of the cross beam 20 is arranged at one end of the cross beam 20 close to the connecting column 10, the connecting sleeve 30 is an annular structure with openings at both ends, the third connecting portion 31 is arranged on the inner side surface of the connecting sleeve 30, and the shapes of the third connecting portion 31 and the first connecting portion 11 are adapted to each other, and the two can be engaged with or separated from each other without the use of fasteners, and the fourth connecting portion 32 is arranged on the outer side surface of the connecting sleeve 30, and the shapes of the fourth connecting portion 32 and the second connecting portion 21 are adapted to each other, and the two can be engaged with or separated from each other without the use of fasteners, which can well ensure the reusability of the connecting column 10, the cross beam 20 and the connecting sleeve 30.

[0041] Furthermore, the connecting sleeve 30 can be used to splice two connecting columns 10. The connecting sleeve 30 used here is not a hollow structure. A cross-partition needs to be arranged inside the connecting sleeve 30 used to connect the two connecting columns 10 so that the two connecting columns 10 can be accurately positioned when they are inserted into the connecting sleeve 30. The two connecting columns 10 spliced ​​with each other are both provided with a first connecting portion 11. The first connecting portions 11 in the two connecting columns 10 are both arranged at a position close to the other connecting column 10, and the ends of the two connecting columns 10 close to the first connecting portions 11 abut against each other, and the two are arranged along the extension direction of their own lengths. Then, the connecting sleeve 30 is inserted into one of the two connecting columns 10, and is sleeved at the intersection of the two connecting columns 10 along the length of the connecting column 10 in the extension direction. Finally, the connecting sleeve 30 is rotated so that the third connecting portion 31 on the connecting sleeve 30 is respectively engaged with the first connecting portions 11 on the two connecting columns 10 to complete the assembly.

[0042] The recyclable assembled beam-column connection structure provided by the present application is compared with the prior art. The recyclable assembled beam-column connection structure of the present application is provided with a connecting sleeve 30 between the connecting column 10 and the cross beam 20, and a first connecting portion 11 is provided on the peripheral side surface of the connecting column 10, and a third connecting portion 31 adapted to the first connecting portion 11 is provided on the inner side surface of the connecting sleeve 30, and the first connecting portion 11 and the third connecting portion 31 are detachably engaged and connected, so that the connecting column 10 and the connecting sleeve 30 can be detachably connected. At the same time, a second connecting portion 21 is provided at the end of the cross beam 20, and a fourth connecting portion 32 is provided on the outer side surface of the connecting sleeve 30, and the second connecting portion 21 and the fourth connecting portion 32 are detachably engaged and connected, so that the cross beam 20 and the connecting sleeve 30 can be detachably connected, so that the integrity of each component of the cross beam 20 and the connecting column 10 can be ensured during the disassembly and assembly process, and the cross beam 20 and the connecting column 10 can be reused, and the disassembly and assembly between the cross beam 20 and the connecting column 10 can be completed efficiently.

[0043] In one embodiment of the present application, please refer to Figures 3 to 5 The first connection part 11 includes a first clamping block 111, and the third connection part 31 includes two third clamping blocks 311, and the two third clamping blocks 311 are respectively limited and set on the opposite sides of the first clamping block 111 along the extension direction of the length of the connecting column 10; or the first connection part 11 includes two first clamping blocks 111, and the third connection part 31 includes a third clamping block 311, and the two first clamping blocks 111 are respectively limited and set on the opposite sides of the third clamping block 311 along the extension direction of the length of the connecting column 10.

[0044] Specifically, in the present embodiment, the third connection part 31 includes two third clamping blocks 311, which are arranged at intervals along the length of the connection sleeve 30 in the extension direction, and a clamping groove for limiting the first clamping block 111 is formed between the two third clamping blocks 311, and both sides of the clamping groove are opening structures. When the connection sleeve 30 is sleeved in the set position of the connection column 10, by driving the connection column 10 and the connection sleeve 30 to rotate relative to each other, the first clamping block 111 on the connection column 10 can be clamped into the clamping groove from one of the openings on both sides of the clamping groove, so as to realize the mutual clamping between the first connection part 11 and the third connection part 31. Similarly, by continuing to drive the connection column 10 and the connection sleeve 30 to rotate relative to each other, the first clamping block 111 on the connection column 10 can leave the clamping groove from one of the openings, so as to realize the mutual separation between the first connection part 11 and the third connection part 31. When the first clamping block 111 is engaged between the two third clamping blocks 311, the two third clamping blocks 311 are located on opposite sides of the length direction of the first clamping block 111, thereby limiting the first clamping block 111 in the length direction and preventing the connecting sleeve 30 from moving along the extension direction of the length of the connection. Through the above arrangement, the connecting column 10 and the connecting sleeve 30 can be quickly disassembled and connected by relative rotation.

[0045] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 5 The number of the first connection parts 11 and the number of the third connection parts 31 are both multiple, and the multiple first connection parts 11 and the multiple third connection parts 31 are all circumferentially and equidistantly distributed.

[0046] Specifically, a plurality of first connection parts 11 are equidistantly distributed on the connection column 10 around the central axis of the connection column 10, and the third connection parts 31 are equidistantly distributed on the inner side surface of the connection sleeve 30 around the central axis of the connection sleeve 30. The width of the gap between two adjacent first connection parts 11 is greater than the width of the third connection part 31, and the width of the gap between two adjacent third connection parts 31 is greater than the width of the first connection part 11, so that when the connection sleeve 30 is installed on the connection column 10, the first connection part 11 and the third connection part 31 are firstly displaced with each other along the length of the connection column 10 in the extension direction, and then the connection sleeve 30 is driven to move along the length of the connection column 10 in the extension direction to a preset installation position, at which time the first connection part 11 is located at the gap between two adjacent third connection parts 31, and it is best to drive the connection sleeve 30 to rotate around its own central axis so that the first connection part 11 and the third connection part 31 are mutually engaged and connected. By providing a plurality of the first connection portion 11 and the third connection portion 31 , it is possible to provide a plurality of engaging positions between the connection sleeve 30 and the connection column 10 , thereby improving the stability of the connection between the two.

[0047] Furthermore, in order to achieve a secure snap-fit ​​connection between the first connection portion 11 and the third connection portion 31 , a layer of elastic rubber coating may be coated on the outer surfaces of the first connection portion 11 and the third connection portion 31 to prevent the two from slipping during use.

[0048] In one embodiment of the present application, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The second connection part 21 includes a plurality of connection sliders 211, and the fourth connection part 32 includes a plurality of connection slots 321; or the second connection part 21 includes a plurality of connection slots 321, and the fourth connection part 32 includes a plurality of connection sliders 211, and the connection slots 321 are slidably connected to the connection sliders 211.

[0049] Specifically, the second connecting portion 21 and the fourth connecting portion 32 are connected by a sliding connection between a slider and a slide groove. The connecting slide groove 321 can limit the moving trajectory of the connecting slider 211, and can also limit the rotation of the connecting slider 211 in the connecting slide groove 321. By setting a sliding connection between the slider and the slide groove between the beam 20 and the connecting sleeve 30, the beam 20 can be stably installed in the connecting sleeve 30 along the set trajectory of the connecting slide groove 321, and can also prevent the beam 20 from rotating in the extension direction around its own length, thereby further improving the stability of the assembly between the beam 20 and the connecting column 10.

[0050] In one embodiment of the present application, please refer to Figure 5 and Figure 6The connecting slider 211 and the connecting slot 321 are wedge-shaped structures that fit each other. The connecting slider 211 and the connecting slot 321 are both extended along the length direction of the connecting column 10, and the width of the connecting slot 321 gradually decreases along the direction of gravity.

[0051] Specifically, the wedge-shaped structure and the conical structure have some similarities. The width of the connecting slider 211 of the wedge-shaped structure gradually decreases or increases along its own extension direction, and the width of the connecting slot 321 of the wedge-shaped structure decreases or increases along its own extension direction. Therefore, when the connecting slider 211 slides to the set position of the connecting slot 321, it is restricted by the wedge-shaped structure and cannot continue to slide along the extension direction of the connecting slot 321. By setting the width of the connecting slot 321 to gradually decrease along the gravity direction, after the connecting slider 211 slides to the set position, the cross beam 20 will not drive the connecting slider 211 at its end to continue to slide along the connecting slot 321 under the action of gravity, so as to achieve the effect of limiting the cross beam 20, further shortening the assembly time and improving the efficiency of disassembly and assembly.

[0052] In one embodiment of the present application, please refer to Figure 2 and Figure 5 The connecting sleeve 30 is a polygonal prism with two ends open and a hollow structure. The polygonal prism can be, but is not limited to, a quadrangular prism, an octagonal prism, and a dodecagonal prism.

[0053] Specifically, compared to a cylinder, the circumferential side surface of a polygonal column is composed of a plurality of equivalent regular quadrilaterals. At the same time, the circumferential side surface of the connecting sleeve 30 needs to be provided with a plurality of fourth connecting portions 32 connected to the cross beam 20. By configuring the connecting sleeve 30 as a polygonal column structure, the fourth connecting portion 32 can be arranged on a plane, which can effectively simplify the structural design between the fourth connecting portion 32 and the connecting sleeve 30.

[0054] In one embodiment of the present application, please refer to Figure 5 The connecting sleeve 30 is an octagonal prism, and the number of the fourth connecting parts 32 is 4. The four fourth connecting parts 32 are circumferentially and equidistantly distributed on four side surfaces of the connecting sleeve 30, and a limiting sliding groove 322 adapted to the second connecting part 21 is formed between two adjacent fourth connecting parts 32.

[0055] Specifically, in this embodiment, the connecting sleeve 30 is an octagonal prism structure with two ends open, and the four fourth connecting parts 32 are respectively arranged at intervals on four sides of the connecting sleeve 30, and each fourth connecting part 32 has a connecting slot 321, so each fourth connecting part 32 can be connected to a cross beam 20. At the same time, two adjacent fourth connecting parts 32 cooperate to form a limiting slot 322 with the same function as the connecting slot 321, and the limiting slot 322 is adapted to the shape of the second connecting part 21 and is also a wedge-shaped structure, so the other four sides of the connecting sleeve 30 can also be connected to a cross beam 20 respectively. In summary, the connecting sleeve 30 can be connected to eight cross beams 20 at the same time, thereby improving the flexibility of the assembly of the entire assembled beam-column connection structure, and can be assembled according to actual needs.

[0056] In one embodiment of the present application, please refer to Figure 8 , further comprising a first positioning member 41, on which a positioning portion 411 is provided. The positioning portion 411 is clamped on the side of the first connecting portion 11 and the second connecting portion 21 to prevent the first connecting portion 11 and the second connecting portion 21 from being separated from each other.

[0057] Specifically, there are two positioning portions 411 on the first positioning member 41, and the two positioning portions 411 are respectively clamped on both sides of the first connecting portion 11 and the second connecting portion 21. When the positioning portions 411 are clamped on both sides of the first connecting portion 11 and the second connecting portion 21, relative rotation cannot occur between the connecting sleeve 30 and the connecting column 10, so that the first clamping block 111 is limited between the two second clamping blocks, thereby further improving the stability of the entire assembled beam-column connection structure.

[0058] Furthermore, if required by the design, the first positioning member 41 may also serve as a cover plate at the connection position between the connecting sleeve 30 and the connecting column 10 to prevent external objects from falling between the connecting sleeve 30 and the connecting column 10 .

[0059] In one embodiment of the present application, please refer to Fig. 9 The assembled beam-column connection structure also includes a second positioning member 42 and a connecting member 43. The first positioning member 41 and the second positioning member 42 are respectively arranged on opposite sides of the fourth connecting portion 32 along the extension direction, and the two ends of the connecting member 43 are respectively connected to the first positioning member 41 and the second positioning member 42 to prevent the first positioning member 41 and the second positioning member 42 from being separated from the fourth connecting portion 32.

[0060] Specifically, when the assembled beam-column connection structure is applied to the top position, since there is no other beam-column connection structure above it to apply a compressive force in the direction of gravity, when encountering strong winds, the external wind will apply a lifting force to the beam-column connection structure, causing the second connection part 21 in the crossbeam 20 to be separated from the fourth connection part 32 in the connection sleeve 30 in the direction opposite to the gravity under the action of external force. Therefore, after the second connection part 21 and the fourth connection part 32 are connected to each other, the first positioning member 41 and the second positioning member 42 are respectively provided on the opposite sides of the second connection part 21 and the fourth connection part 32 in the direction of gravity, and at the same time, a connecting member 43 is provided between the first positioning member 41 and the second positioning member 42 to prevent the second connection part 21 and the fourth connection part 32 from being separated under the action of external force, thereby further improving the stability of the entire assembled beam-column connection structure.

[0061] See also Fig.10 The present application also provides an assembly method, which includes the following steps: sleeve the connecting sleeve 30 on the connecting column 10, and align the first connecting portion 11 in the connecting column 10 and the third connecting portion 31 in the connecting sleeve 30 along the length of the connecting column 10; the second step: sleeve the connecting sleeve 30 to a set position along the length of the connecting column 10, and then drive the connecting sleeve 30 to rotate so that the first connecting portion 11 and the third connecting portion 31 are engaged with each other; the third step: engage the limit block 50 in one of the The first connecting part 11 and the third connecting part 31 are on the side to prevent the connecting sleeve 30 and the connecting column 10 from rotating relative to each other around the central axis of the connecting column 10; the fourth step: the second connecting part 21 in the crossbeam 20 and the fourth connecting part 32 in the connecting sleeve 30 are engaged and connected with each other; the fifth step: the positioning block 40 is engaged on the side of the other first connecting part 11 and the third connecting part 31 to prevent the first connecting part 11 and the third connecting part 31 from rotating relative to each other around the central axis of the connecting column 10; the sixth step: the limit block 50 can be taken out.

[0062] The assembly method provided in the present application adopts the recyclable assembled beam-column connection structure in the above-mentioned embodiments, and therefore also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
