[0022] The present invention also provides a method for connecting steel structure columns, which includes the steel structure column connection structure described in any of the preceding claims, comprising the following steps:

[0023] S1: Use software to generate a building model. The software generates the specifications and quantity of steel structure columns based on the building model, and generates assembly drawings for the steel structure columns.

[0024] S2: During the installation of each steel structure column, the column is first inserted into the bottom cylinder, so that the two rotating parts and the first sliding groove are aligned and continue to slide downward. When the rotating parts pass through the clamping block, the rotating parts continue to slide downward along the connecting rod until the rotating parts abut against the positioning block. At this time, the limiting groove engages with the clamping block. Continue the operation to engage the arc-shaped block and arc-shaped groove of the cylinder cover.

Then operate the positioning part to disengage the cylinder cover and the bottom cylinder and reconnect the column and the bottom cylinder correctly.

[0026] The steel column connection structure provided by this invention has the following beneficial effects:

[0027] 1. This invention enables the disassembly and installation of the bottom cylinder by operating an adjusting component. The adjusting component facilitates the assembly and rapid disassembly of the pipe column and the bottom cylinder. A cylinder cover is fitted onto the pipe column, and the cylinder cover and the bottom cylinder are detachably connected. After assembly between the pipe column and the bottom cylinder, the cylinder cover provides internal protection. Simultaneously, a positioning component further adjusts the distance between the cylinder cover and the bottom cylinder, causing the positioning component to abut against the cylinder cover and promote the connection between the cylinder cover and the bottom cylinder. This provides protection after the bottom cylinder and the pipe column are connected to the corresponding steel structure column.

[0028] 2. The present invention also allows the steel structure column connection structure to be prefabricated on steel structure columns of different specifications, and then assembled and connected according to the actual site requirements. The assembly process is relatively convenient and quick to achieve the connection, realizing the prefabricated connection of steel structure columns to improve on-site operation efficiency.

[0029] 3. The present invention also enables the assembly of the cylinder cover and the bottom cylinder by setting the arc block and the arc groove, so that in the assembly of the cylinder cover and the bottom cylinder, it is not necessary to first align the first sliding groove and the second sliding groove before connecting the two. The assembly of the cylinder cover and the bottom cylinder can be completed first, and then the alignment can be completed by rotating the cylinder cover. At the same time, the efficiency of the assembly of the cylinder cover and the bottom cylinder is ensured.

[0030] 4. The present invention also allows for the use of a crane to lift the pipe column when it is necessary to disassemble the pipe column and the bottom cylinder. This allows the entire assembly after connecting the pipe column and the positioning block to be lifted towards the cylinder cover until the V-shaped block of the rotating component contacts the conical groove. During the upward movement, the V-shaped block slides along the side wall of the conical groove. At this time, the V-shaped block of the rotating component rotates towards the pipe column with the rotating rod as the center. Meanwhile, the L-shaped block rotates away from the clamping block, causing the L-shaped block to separate from the clamping block.

[0031] 5. The present invention also enables the connection of the limiting groove and the clamping block to play a guiding role in the connection process, thereby promoting the overall accurate alignment of the steel structure connecting column connection structure. Based on the connection structure of the steel structure connecting column, the accuracy of the assembly process is further improved. Attached Figure Description

[0042] like Figure 1-8 As shown, the present invention provides a steel column connection structure, which includes:

[0043] A bottom cylinder 1, with a positioning block 2 at its bottom; a tubular column 3, detachably connected to the bottom cylinder 1, with an adjusting component at one end of the tubular column 3 near the bottom cylinder 1, the adjusting component being used for assembly and quick disassembly between the tubular column 3 and the bottom cylinder 1; a cylinder cover 4, detachably connected to the bottom cylinder 1, also fitted onto the tubular column 3; and a positioning component 5, disposed on the tubular column 3 to adjust the distance between the cylinder cover 4 and the bottom cylinder 1. Figure 1-8 As shown, a steel column connection structure is provided, which connects the bottom cylinder 1 and the pipe column 3. The bottom cylinder 1 and the pipe column 3 can be prefabricated and connected to the steel column at both ends of steel column of different specifications. Then, on site, the appropriate steel column is selected for alignment and connection as needed. The bottom cylinder 1 has a hollow structure with a positioning block 2 inside. The positioning block 2 is a counterweight block with a weight of 2 / 3 of the weight of the pipe column, which can be used to connect with the pipe column 3. The pipe column 3 and the bottom cylinder 1 are detachably connected. The pipe column 3 can be disassembled and installed with the bottom cylinder 1 by operating the adjustment component, and the assembly and quick disassembly of the pipe column 3 and the bottom cylinder 1 can be achieved through the adjustment component. The pipe column 3 is also fitted with a cylinder cover 4, which is detachably connected to the bottom cylinder 1. After the pipe column 3 and the bottom cylinder 1 are assembled, the cylinder cover 4 protects the inside of the pipe column 3. At the same time, the positioning part 5 is used to further adjust the distance between the cylinder cover 4 and the bottom cylinder 1, so that the positioning part 5 abuts against the cylinder cover 4, promoting the connection between the cylinder cover 4 and the bottom cylinder 1. This provides protection for the bottom cylinder 1 and the pipe column 3 after the corresponding steel structure column is connected. The steel structure column connection structure in this application can be set in advance on prefabricated steel structure columns of different specifications, and then assembled and connected according to the actual site requirements. The assembly process is relatively convenient and quick to achieve the connection, thereby improving the efficiency of on-site operations.

[0044] In some embodiments, the positioning block 2 and the inner wall of the bottom cylinder 1 are slidably connected, and a connecting rod 6 is provided at the top center of the positioning block 2, with a clamping block 7 provided at the end of the connecting rod 6 away from the positioning block 2. Figure 1-8 As shown, the positioning block 2 and the inner wall of the bottom cylinder 1 are slidably connected. 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 clamping block 7 is set to facilitate the connection or disconnection between the adjusting component and the positioning block 2.

[0045] In some embodiments, the bottom cylinder 1 has two opposite inner sides respectively provided with first sliding grooves 8, the top of the cylinder cover 4 has two opposite inner sides respectively provided with second sliding grooves 9, and the top of the bottom cylinder 1 has a pair of arc-shaped grooves 10, each arc-shaped groove 10 being distributed between the two first sliding grooves 8 along the top edge of the bottom cylinder 1; the bottom of the cylinder cover 4 has a pair of arc-shaped blocks 11, one end of each arc-shaped block 11 being close to two of the second sliding grooves 9 along the bottom edge of the cylinder cover 4, and leaving a gap between each block and the other non-close second sliding groove 9; the cylinder cover 4 and the bottom cylinder 1 are engaged by the arc-shaped blocks 11 and the arc-shaped grooves 10, and the arc-shaped blocks 11 slide within the arc-shaped grooves 10. Figure 1-8 As shown, the first sliding groove 8 on the two opposing inner walls of the bottom cylinder 1 and the second sliding groove 9 on the two opposing inner walls of the cylinder cover 4 are configured such that when the cylinder cover 4 and the bottom cylinder 1 are engaged by the sliding block and the arc groove 10, the cylinder cover 4 can be rotated within the arc groove 10, so that whether 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 groove 8 and the second sliding groove 9 are aligned together, so that the first sliding groove 8 and the second sliding groove 9 form a connected first sliding groove 8 and the second sliding groove 9 after the cylinder cover 4 and the bottom cylinder 1 are connected. This allows the adjusting component to slide from the bottom of the bottom cylinder 1 to the top of the cylinder cover 4, which facilitates the alignment and quick assembly and disassembly of the adjusting component between the column 3 and the bottom cylinder 1.

[0046] Specifically, the arc-shaped block 11 and the arc-shaped groove 10 allow the first sliding groove 8 and the second sliding groove 9 to be aligned before connecting them during the assembly of the cover 4 and the bottom cylinder 1. The cover 4 and the bottom cylinder 1 can be assembled first, and then the alignment can be completed by rotating the cover 4. This ensures the efficiency of the assembly of the cover 4 and the bottom cylinder 1.

[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 being spaced apart from each other and slidably connected to the inner wall of the bottom cylinder 1, one end of the connecting plate 12 being connected to the pair of split sliders 13, and the other end of the connecting plate 12 being connected to the column 3, a fixing block 14 and a pair of rotating members being connected between the pair of split sliders 13, the two sides of the fixing block 14 being respectively connected to the centers of the split sliders 13, the rotating members being respectively disposed at both ends of the fixing block 14 and rotatably connected to the split sliders 13, and the pair of rotating members being used for detachable connection between the clamping blocks 7. Figure 1-8 As shown, the connection between the connecting plate 12 and the pair of split sliders 13 can be achieved by bonding, bolting, or welding. Meanwhile, the fixing block 14 is positioned opposite to the center of the pair of split sliders 13 in the height and radial directions, facilitating the connection between the pair of split sliders 13. The rotating component is positioned on both sides of the fixing block 14 and is rotatably connected to the split sliders 13. By operating the rotating component, when the split slider 13 slides close to the clamping block 7, the rotating component and the clamping block 7 are connected, or when it moves away, they are disassembled.

[0048] In some embodiments, the rotating component includes: a V-shaped block 15 and an L-shaped block 16. The L-shaped block 16 is disposed near the fixed block 14, and one 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. The other end of the L-shaped block 16 extends toward the column 3 and is spaced apart from the column 3. A pair of rotating rods 17 are disposed near the V-shaped block 15 between a pair of split sliders 13, and the V-shaped block 15 is rotatably connected to the rotating rods 17 respectively. One side of the inner wall of the bottom cylinder 1 is slidably connected to the first sliding groove 8 and the second sliding groove 9, respectively. Rotating grooves 18 are respectively provided on the sides of the V-shaped blocks 15 that are close to each other. Springs 19 are respectively provided between the rotating grooves 18 and the fixed blocks 14. Limiting rods 20 are respectively provided on the side of the fixed blocks 14 that are close to the rotating grooves 18. Linkage rods 21 are respectively provided in the rotating grooves 18. One end of each linkage rod 21 is rotatably connected to the rotating groove 18. The two ends of the springs 19 are respectively sleeved between the linkage rods 21 and the limiting rods 20, and the springs 19 abut against the V-shaped blocks 15 and the fixed blocks 14. Figure 1-8As shown, the rotating component includes a V-shaped block 15 and an L-shaped block 16. When the column 3 where the adjusting component is located slides relative to the bottom cylinder 1, the short side of the L-shaped block 16 and the top of the clamping block 7 are relatively parallel. At this time, the side of the V-shaped block 15 near the bottom cylinder 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. When the rotating component deflects, the short side of the L-shaped block 16 and the clamping block 7 are installed and disassembled. The linkage rod 21 in the rotation groove 18 of the V-shaped block 15 is equivalent to the rotation groove 18 being rotatably connected. When the spring between the linkage rod 21 and the limit rod 20... The spring 19 allows the rotating part to deflect around the rotating rod 17. For example, when the rotating part slides down the first sliding groove 8, the L-shaped block 16 continues to move downward after contacting the clamping block 7. During the downward movement along the L-shaped block 16, the spring 19 is compressed, causing the two V-shaped blocks 15 to rotate towards the column 3, so that the L-shaped block 16 contacts the positioning block 2. After that, due to the action of the spring 19, the spring 19 returns to its original deformation, so that the L-shaped block 16 directly contacts the connecting rod 6. The clamping block 7 restricts the L-shaped block 16 from moving upward, thereby realizing the connection between the column 3 and the positioning block 2. The connection process is relatively fast.

[0049] In some embodiments, an arc-shaped surface 22 is provided at one end of the L-shaped block 16 where the short side is located, and a rubber layer is provided on the arc-shaped surface 22. For example... Figure 1-8 As shown, an arc-shaped surface 22 is provided on the short side of the L-shaped block 16 near the end of the clamping block 7, so that as the L-shaped block 16 slides downward, the arc-shaped surface 22 can promote its continued downward sliding. During this process, the two V-shaped blocks 15 rotate toward the column 3, and the spring 19 is compressed, completing its relative rotation. The rubber layer on the arc-shaped surface 22 promotes the friction effect between the two, so that the process can be carried out relatively slowly to prevent damage to the spring 19 due to excessive speed.

[0050] In some embodiments, the cylindrical cover 4 has a through hole 23 at its center, the tubular column 3 is directly spaced from the through hole 23, and the bottom of the cylindrical cover 4 has a tapered groove 24 at the edge of the through hole 23. When the adjusting member abuts against the cylindrical cover 4, the end of the V-block 15 near the tubular column 3 is slidably connected to the tapered groove 24; the top of the cylindrical cover 4 has 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 central through-hole 23 allows the cylinder cover 4 to be fitted onto the tube column 3. The conical groove 24 on the edge of the through-hole 23 at the bottom of the cylinder cover 4 allows for disassembly of the tube column 3 and the bottom cylinder 1, or for misalignment, by using a crane to lift the tube column 3. This lifts the entire assembly of the tube column 3 and the positioning block 2 towards the cylinder cover 4 until the V-shaped block 15 of the rotating component contacts the conical groove 24. As it continues to move upward, the V-shaped block 15 slides along the side wall of the conical groove 24. At this time, the V-shaped block 15 of the rotating component rotates towards the tube column 3 with the rotating rod 17 as the center. Meanwhile, the L-shaped block 16 rotates away from the clamping block 7, causing the L-shaped block 16 and the clamping block 7 to separate. During this process, the spring 19 is compressed, and the positioning block 2 separates to the bottom of the bottom cylinder 1, completing the disassembly of the tube column 3 and the bottom cylinder 1.

[0051] In some embodiments, the bottom of each pair of split sliders 13 is provided with a limiting groove 26 that is adapted to the clamping block 7. For example... 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 achieving the connection between the two and promoting the tightness of the connection between the column 3 and the bottom cylinder 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, promoting the overall alignment accuracy of the connection structure. Based on the connection structure of the steel column, the accuracy of the assembly process is further improved.

[0052] In some embodiments, the top of the positioning member 5 is provided with a first connecting portion 27, and the bottom of the positioning member 5 is provided with a second connecting portion 28. The second connecting portion 28 is engaged with the positioning groove 25. The column 3 is provided with a threaded portion 29, and the center of the positioning member 5 is provided with a threaded hole adapted to the threaded portion 29. The positioning member 5 and the column 3 are threaded together. Figure 1-8 As shown, the first connecting part 27 at the top of the positioning part 5 facilitates the operation of the positioning part 5, while the second connecting part 28 and the positioning groove 25 are engaged. During the connection of the column 3, the cylinder cover 4 is sleeved on the column 3 and located above the adjusting part. The positioning part 5 is located above the cylinder cover 4. After the assembly of the positioning part 5 is completed, the cylinder cover 4 is covered, and then the first sliding groove 8 and the second sliding groove 9 are aligned. Then, the first connecting part 27 is rotated to screw the positioning part 5 and the column 3, so that the second connecting part 28 of the positioning part 5 and the positioning groove 25 are engaged to fix the position between the cylinder cover 4 and the bottom cylinder 1, thus completing the connection of the steel structure column. Conversely, when disassembly is required, the adjusting part is first operated to disengage the adjusting part from the positioning block 2, then the positioning part 5 is disengaged from the positioning groove 25, and then the cylinder cover 4 is disengaged from the bottom cylinder 1 and can be pulled out.

[0053] The present invention also provides a method for connecting steel structure columns, which includes the steel structure column connection structure described in any of the preceding claims, comprising the following steps:

[0054] S1: Use software to generate a building model. The software generates the specifications and quantity of steel structure columns based on the building model, and generates assembly drawings for the steel structure columns.

[0055] S2: During the installation of each steel structure column, the column 3 is first inserted into the bottom cylinder 1, so that the two rotating parts and the first sliding groove 8 are aligned and continue to slide downward. When the rotating part passes through the clamping block 7, the rotating part continues to slide downward along the connecting rod 6 until the rotating part abuts the positioning block 2. At this time, the limiting groove 26 engages the clamping block 7. Continue the operation to engage the arc-shaped block 11 and the arc-shaped groove 10 of the cylinder cover 4. Rotate the cylinder cover 4 so that the arc-shaped block 11 abuts the two arc-shaped grooves 10 respectively to form a limit. Then operate the positioning part 5 so that the positioning part 5 and the column 3 are screwed together, so that the positioning part 5 abuts in the positioning groove 25.

[0056] S3: Check whether the installation position of each steel structure column is accurate. Otherwise, operate the rotating part and the positioning block 2 to slide along the first sliding groove 8 and the second sliding groove 9 towards the top of the cylinder cover 4 until the rotating part and the positioning block 2 are disengaged. Then operate the positioning part 5 to disengage the cylinder cover 4 and the bottom cylinder 1, and reconnect the correct pipe column 3 and the bottom cylinder 1.

[0057] Specifically, the software can be Autodesk Revit. To build the building, a building model is constructed. Based on the existing prefabricated panel specifications, the software generates the required specifications and quantity of steel structure columns, the quantity corresponding to each specification, and the installation position. It also generates assembly drawings for the steel structure columns. In the construction of the foundation, it is only necessary to fill the bottom cylinder 1 according to the installation position of the model, and then pour concrete on the outside to form a concrete layer.

[0058] Specifically, during the process of the tubing 3 extending into the bottom cylinder 1, the two rotating parts are first aligned with the first sliding groove 8, and then continue to slide downwards. When the L-shaped block 16 contacts the clamping block 7, it continues to move downwards. As the L-shaped block 16 moves downwards, the spring 19 is compressed, causing the two V-shaped blocks 15 to rotate towards the tubing 3, until the L-shaped block 16 contacts the positioning block 2. Then, due to the action of the spring 19, the spring 19 returns to its original deformation, allowing the L-shaped block 16 to directly contact the connecting rod 6. The clamping block 7 restricts the upward movement of the L-shaped block 16, thereby achieving the connection between the tubing 3 and the positioning block 2. Afterwards, as the rotating parts continue to move downwards, the clamping block 7 is engaged in the limiting groove 26. At this time, the adjusting parts and the positioning block 2 are aligned. The cylinder cover 4 is then fixed in place by rotating within the arc-shaped groove 10. Whether rotated clockwise or counterclockwise, one end of each arc-shaped block 11 contacts one end of a different arc-shaped groove 10. This ensures that after the cylinder cover 4 and the bottom cylinder 1 are assembled, the first sliding groove 8 and the second sliding groove 9 are aligned, forming a connected first sliding groove 8 and second sliding groove 9. Subsequently, the first connecting part 27 is rotated, causing the positioning member 5 and the column 3 to be screwed together. This causes the second connecting part 28 of the positioning member 5 to engage with the positioning groove 25, fixing the position between the cylinder cover 4 and the bottom cylinder 1 and completing the connection of the steel structure column.

[0059] Specifically, when disassembly is required or an assembly error is found after inspecting the installation position of each steel structure column, a crane can be used to lift the column 3, so that the entire assembly of the column 3 and the positioning block 2 is lifted towards the cylinder cover 4 until the V-shaped block 15 of the rotating part contacts the conical groove 24. During the upward movement, the V-shaped block 15 slides along the side wall of the conical groove 24. At this time, the V-shaped block 15 of the rotating part rotates towards the column 3 with the rotating rod 17 as the center. At this time, the L-shaped block 16 rotates away from the clamping block 7, so that the L-shaped block 16 and the clamping block 7 are separated.
