The bottom tube 1 and the pipe column 3 can be connected to the steel structure column in advance during the prefabrication process, and are respectively connected to the two ends of steel structure columns of different specifications. Then, appropriate steel structure columns are selected on site for alignment connection according to needs; wherein, the bottom tube 1 is a hollow structure inside, and a positioning block 2 is arranged inside. The positioning block 2 is a counterweight block, and its weight is 2 / 3 of the weight of the pipe column, and it can be connected to the pipe column 3; the pipe column 3 and the bottom tube 1 are detachably connected, and the disassembly and installation of the bottom tube 1 are realized by operating the adjusting piece, and the assembly and quick disassembly between the pipe column 3 and the bottom tube 1 are realized by the adjusting piece. A cylinder cover 4 is also provided on the pipe column 3, and the cylinder cover 4 and the bottom cylinder 1 are detachably connected. After being assembled between the pipe column 3 and the bottom cylinder 1, the inside thereof is protected by the cylinder cover 4. At the same time, the distance between the cylinder cover 4 and the bottom cylinder 1 is further adjusted by the positioning member 5, so that the positioning member 5 abuts against the cylinder cover 4, thereby promoting the connection between the cylinder cover 4 and the bottom cylinder 1; after the bottom cylinder 1 and the pipe column 3 realize the connection of the corresponding steel structure columns, protection is provided for them. The steel structure column connection structure in the present application can be set in advance on prefabricated steel structure columns of different specifications, and then assembled and connected according to actual site needs. The connection is relatively convenient and quick during the assembly process, so as to improve site operation efficiency.

[0044] In some embodiments, the positioning block 2 is slidably connected to the inner wall of the bottom tube 1, a connecting rod 6 is provided at the top center of the positioning block 2, and a clamping block 7 is provided at one end of the connecting rod 6 away from the positioning block 2. Figure 1-8 As shown, the positioning block 2 is slidably connected to the inner wall of the bottom tube 1. The positioning block 2 is a heavy metal block. The connecting rod 6 connects the positioning block 2 and the clamping block 7. The connection method can be bonding, bolting or welding. The setting of the clamping block 7 facilitates the establishment of connection or disconnection between the adjusting member and the positioning block 2.

[0045] In some embodiments, the two opposite inner sides of the bottom tube 1 are respectively provided with a first sliding groove 8, the two opposite inner sides of the tube cover 4 are respectively provided with a second sliding groove 9, the top of the bottom tube 1 is provided with a pair of arc grooves 10, each of which is distributed between the two first sliding grooves 8 along the top edge of the bottom tube 1; the bottom of the tube cover 4 is provided with a pair of arc blocks 11, one end of each arc block 11 is respectively close to the two second sliding grooves 9 along the bottom edge of the tube cover 4, and a gap is left between each of the arc blocks 11 and the other second sliding groove 9 that is not close; the tube cover 4 and the bottom tube 1 are clamped by the arc blocks 11 and the arc grooves 10, and the arc blocks 11 slide in the arc grooves 10. Figure 1-8 As shown, the first sliding grooves 8 on the two opposite inner walls of the bottom cylinder 1 and the second sliding grooves 9 on the two opposite inner walls of the cylinder cover 4 are arranged. When the cylinder cover 4 and the bottom cylinder 1 are clamped between the sliding block and the arc groove 10, the cylinder cover 4 is operated to rotate in the arc groove 10, so that no matter it rotates clockwise or counterclockwise, one end of each arc block 11 can contact one end of a different arc groove 10. In this way, after the cylinder cover 4 and the bottom cylinder 1 are assembled, the first sliding grooves 8 and the second sliding grooves 9 are aligned together, so that the first sliding grooves 8 and the second sliding grooves 9 form the connected first sliding grooves 8 and the second sliding grooves 9 after the cylinder cover 4 and the bottom cylinder 1 are connected, so that the adjusting part can slide from the bottom of the bottom cylinder 1 to the top of the cylinder cover 4, which is convenient for the adjusting part to align the pipe column 3 and the bottom cylinder 1 and to quickly assemble and disassemble.

[0046] Specifically, the arrangement of the arc block 11 and the arc groove 10 makes it unnecessary to directly align the first sliding groove 8 and the second sliding groove 9 before connecting the two during the assembly of the cylinder cover 4 and the bottom cylinder 1. Instead, the cylinder cover 4 and the bottom cylinder 1 can be assembled first, and then the cylinder cover 4 can be rotated to complete the alignment. At the same time, the efficiency of the assembly of the cylinder cover 4 and the bottom cylinder 1 is ensured.

[0047] In some embodiments, the adjusting member includes: a connecting plate 12 and a pair of split sliders 13, the pair of split sliders 13 are arranged with a gap between each other and are respectively slidably connected to the inner wall of the bottom tube 1, one end of the connecting plate 12 is connected to the pair of split sliders 13, and the other end of the connecting plate 12 is connected to the pipe column 3, a fixed block 14 and a pair of rotating members are connected between the pair of split sliders 13, the two sides of the fixed block 14 are respectively connected to the center of the split slider 13, the rotating members are respectively arranged at the two ends of the fixed block 14 and the rotating members are rotatably connected to the split slider 13, and the pair of rotating members are used for the detachable connection between the clamping blocks 7. Figure 1-8 As shown, the connection between the connecting plate 12 and a pair of split sliders 13 can be achieved by bonding, bolting or welding. At the same time, the fixed block 14 is relatively arranged at the center of the pair of split sliders 13 in the height direction and radial direction. The fixed block 14 promotes the connection between the pair of split sliders 13. The rotating member is arranged on both sides of the fixed block 14 and is rotatably connected to the split slider 13. By operating the rotating member to rotate, when the split slider 13 slides close to the clamping block 7, the rotating member and the clamping block 7 are connected or disassembled when they are far away.

[0048] In some embodiments, the rotating member includes: a V-shaped block 15 and an L-shaped block 16, wherein the L-shaped block 16 is arranged close to the fixed block 14, and a short side of the L-shaped block 16 extends toward the clamping block 7, the long side of the L-shaped block 16 is connected to one end of the V-shaped block 15, and the angle between the long side of the L-shaped block 16 and the V-shaped block 15 is an obtuse angle, and the other end of the L-shaped block 16 extends toward the pipe column 3 and is provided with a gap between the pipe column 3; a pair of rotating rods 17 are arranged between the pair of split sliders 13 close to the V-shaped block 15, and the V-shaped blocks 15 are rotatably connected to the rotating rods 17 respectively; the V-shaped block 15 is close to the fixed block 14, and the short side of the L-shaped block 16 extends toward the clamping block 7, and the long side of the L-shaped block 16 is connected to the V-shaped block 15, and the angle between the long side of the L-shaped block 16 and the V-shaped block 15 is an obtuse angle, and the other end of the L-shaped block 16 extends to the pipe column 3 and is provided with a gap between the pipe column 3; a pair of rotating rods 17 are arranged between the pair of split sliders 13 close to the V-shaped block 15, and the V-shaped blocks 15 are rotatably connected to the rotating rods 17 respectively; One side of the inner wall of the bottom cylinder 1 is respectively connected to the first sliding groove 8 and the second sliding groove 9 in a sliding manner. The V-shaped blocks 15 are respectively provided with rotating grooves 18 on the sides close to each other. Springs 19 are respectively provided between the rotating grooves 18 and the fixed blocks 14. The fixed blocks 14 are respectively provided with limit rods 20 on the sides close to the rotating grooves 18. Linkage rods 21 are respectively provided in the rotating grooves 18. One end of the linkage rod 21 is respectively connected to the rotating grooves 18 in a rotating manner. The two ends of the spring 19 are respectively sleeved between the linkage rod 21 and the limit rod 20, and the spring 19 abuts against the V-shaped blocks 15 and the fixed blocks 14. Figure 1-8As shown, the rotating member includes a V-shaped block 15 and an L-shaped block 16. When the pipe column 3 where the adjusting member is located slides relative to the bottom tube 1, the short side of the L-shaped block 16 is relatively parallel to the top of the clamping block 7. At this time, the side of the V-shaped block 15 close to the bottom tube 1 slides in the first sliding groove 8 and the second sliding groove 9. The V-shaped block 15 is rotatably connected to the rotating rod 17 respectively. When the rotating member is deflected, the short side of the L-shaped block 16 and the clamping block 7 are installed and disassembled. Among them, the linkage rod 21 in the rotating groove 18 of the V-shaped block 15 is equivalent to the rotating groove 18 being a rotating connection. When the spring between the linkage rod 21 and the limit rod 20 19 allows its rotating part to deflect around the rotating rod 17. For example, when its rotating part slides downward in the first sliding groove 8, when the L-shaped block 16 contacts the clamping block 7 and continues to move downward, during the downward movement of the L-shaped block 16, the spring 19 is compressed, causing the two V-shaped blocks 15 to rotate toward the pipe column 3, so that the L-shaped block 16 contacts the positioning block 2. Afterwards, due to the action of the spring 19, the spring 19 recovers its deformation, causing the L-shaped block 16 to directly contact the connecting rod 6, and the clamping block 7 limits the L-shaped block 16 upward, thereby realizing the connection between the pipe column 3 and the positioning block 2, and the connection process is relatively fast.

[0049] In some embodiments, a curved surface 22 is disposed at one end of the short side of the L-shaped block 16, and a rubber layer is disposed on the curved surface 22. Figure 1-8 As shown, an arc surface 22 is provided on one end of the short side of the L-shaped block 16 near the clamping block 7, so that when the L-shaped block 16 moves downward, the arc surface 22 can promote it to continue to slide downward. During this process, the two V-shaped blocks 15 rotate toward the pipe column 3, and the spring 19 is compressed to complete their relative rotation. The rubber layer on the arc surface 22 promotes the friction between the two, so that the process can be carried out relatively slowly to prevent the spring 19 from being damaged due to excessive speed.

[0050] In some embodiments, the cylinder cover 4 is provided with a through hole 23 in the center, the pipe column 3 and the through hole 23 are directly spaced apart, the bottom of the cylinder cover 4 is provided with a conical groove 24 at the edge of the through hole 23, and when the adjusting member abuts against the cylinder cover 4, the end of the V-shaped block 15 close to the pipe column 3 is slidably connected with the conical groove 24; the top of the cylinder cover 4 is provided with a positioning groove 25 at the edge of the through hole 23, and the positioning member 5 abuts against the positioning groove 25. Figure 1-8As shown, the cylinder cover 4 can be sleeved on the pipe column 3 through the central through hole 23. The conical groove 24 on the edge of the through hole 23 at the bottom of the cylinder cover 4 is set. When the pipe column 3 and the bottom cylinder 1 need to be disassembled, or when they are misaligned, a crane can be used to hoist the pipe column 3, so that the whole connected with the pipe column 3 and the positioning block 2 is lifted toward the cylinder cover 4 until the V-block 15 of the rotating part contacts the conical groove 24. In the process of continuing to move upward, the V-block 15 slides along the side wall of the conical groove 24. At this time, the V-block 15 of the rotating part rotates toward the pipe column 3 with the rotating rod 17 as the center. At this time, the L-block 16 rotates away from the clamping block 7, so that the L-block 16 and the clamping block 7 are separated. In this process, the spring 19 is compressed, the positioning block 2 is separated to the bottom of the bottom cylinder 1, and the disassembly between the pipe column 3 and the bottom cylinder 1 is completed.

[0051] In some embodiments, the bottom of the pair of split sliders 13 are respectively provided with limiting grooves 26 adapted to the clamping block 7. Figure 1-8 As shown, after the L-shaped block 16 of the rotating part extends into the bottom of the clamping block 7, the limiting groove 26 at the bottom of the split slider 13 continues to engage with the clamping block 7, thereby realizing the subsequent connection between the two and promoting the tight effect after the connection between the pipe column 3 and the bottom tube 1. At the same time, the connection between the limiting groove 26 and the clamping block 7 can play a guiding role in the connection process, promote the overall accurate alignment of the connection structure, and further improve the accuracy of the assembly process on the basis of the connection structure of the steel structure column.

[0052] In some embodiments, the top of the positioning member 5 is provided with a first connection portion 27, the bottom of the positioning member 5 is provided with a second connection portion 28, the second connection portion 28 is clamped with the positioning groove 25, the pipe column 3 is provided with a screw connection portion 29, the center of the positioning member 5 is provided with a screw hole adapted to the screw connection portion 29, and the positioning member 5 is screwed with the pipe column 3. Figure 1-8 As shown, the first connecting portion 27 at the top of the positioning member 5 is convenient for operating the positioning member 5, and the second connecting portion 28 and the positioning groove 25 are clamped together. During the connection process of the pipe column 3, the cylinder cover 4 is sleeved on the pipe column 3 and is located above the adjusting member, and the positioning member 5 is arranged above the cylinder cover 4. When the assembly of the positioning member 5 is completed, the cylinder cover 4 is covered, and then the first sliding groove 8 and the second sliding groove 9 are aligned, and then the first connecting portion 27 is rotated to make the positioning member 5 and the pipe column 3 screwed, so that the second connecting portion 28 of the positioning member 5 and the positioning groove 25 are clamped to fix the position between the cylinder cover 4 and the bottom cylinder 1, and complete the connection of the steel structure column. Conversely, when disassembly is required, the adjusting member is first operated to disengage the adjusting member and the positioning block 2, and then the positioning member 5 and the positioning groove 25 are disengaged, and then the cylinder cover 4 and the bottom cylinder 1 are disengaged, and it can be pulled out.

[0053] The present invention also provides a steel structure column connection method, which includes the steel structure column connection structure described in any of the preceding items, and includes the following steps:

[0054] S1: Generate a building model using software. The software generates the specifications and quantity of steel structure columns based on the building model, and generates assembly drawings of the steel structure columns;

[0055] S2: During the installation of each steel structure column, first extend the pipe column 3 into the bottom cylinder 1, so that the two rotating members and the first sliding groove 8 are aligned and continue to slide downward. After the rotating member passes through the clamping block 7, the rotating member continues to slide downward along the connecting rod 6 until the rotating member abuts the positioning block 2. At this time, the limiting groove 26 engages the clamping block 7; continue to operate to engage the arc block 11 and the arc groove 10 of the cylinder cover 4, rotate the cylinder cover 4 so that the arc block 11 respectively abuts the two arc grooves 10 to form a limit, and then operate the positioning member 5 so that the positioning member 5 and the pipe column 3 are screwed together, so that the positioning member 5 abuts in the positioning groove 25;

[0056] S3: Check whether the installation position of each steel structure column is accurate. If not, operate the rotating member and the positioning block 2 to slide along the first sliding groove 8 and the second sliding groove 9 toward the top of the cylinder cover 4 until the rotating member and the positioning block 2 are disengaged. Then operate the positioning member 5 to disengage the cylinder cover 4 and the bottom cylinder 1, and reconnect the pipe column 3 and the bottom cylinder 1 correctly.

[0057] Specifically, the software can be Autodesk Revit, which builds a building model according to the building to be built. The software generates the specifications and quantity of the required steel structure columns according to the specifications of the currently existing assembly panels, generates the quantity corresponding to each specification, and the installation position, and generates the assembly drawings of the steel structure columns. When constructing the foundation, it is only necessary to fill the bottom tube 1 according to the installation position of the model, and then pour concrete on the outside to form a concrete layer.

[0058] Specifically, in the process of the pipe column 3 extending into the bottom tube 1, the two rotating members are first aligned with the first sliding groove 8, and are allowed to continue to slide downward. When the L-shaped block 16 contacts the clamping block 7, it continues to move downward. In the process of moving downward along the L-shaped block 16, the spring 19 is compressed, causing the two V-shaped blocks 15 to rotate toward the pipe column 3, so that the L-shaped block 16 contacts the positioning block 2. Afterwards, due to the action of the spring 19, the spring 19 recovers its deformation, causing the L-shaped block 16 to directly contact the connecting rod 6. The clamping block 7 restricts the L-shaped block 16 upward, thereby realizing the connection between the pipe column 3 and the positioning block 2. Afterwards, when the rotating member continues to move downward, the clamping block 7 is clamped in the limiting groove 26.
