Description

Technical Field

[0001] This invention relates to the field of inclined steel column construction technology, and in particular to an inclined steel column splicing and installation structure and method. Background Technology

[0002] The installation of inclined steel columns is a common method on construction sites. Compared to traditional steel columns, which are mostly perpendicular to the ground, have a small range of center of gravity changes, and are easy to position, designing the steel columns at unconventional installation angles can meet the dual requirements of green building and aesthetics in modern architecture. However, during construction, the inclined steel columns deform exceptionally complexly under the combined effects of their own weight and additional bending moments. This not only makes correction difficult and prolongs the construction period but also poses significant safety risks. Furthermore, the installation process typically uses temporary connecting positioning plates for fixation. Due to the non-adjustability of these plates, unequal stress on the two sides can easily lead to safety accidents.

[0003] Chinese invention patent application CN107386664A discloses a fine-tuning device and construction method for connecting inclined steel columns, comprising: setting a first lower connecting plate and a lower support plate on the lower section of the steel column, and setting a first upper connecting plate and an upper support plate on the upper section of the steel column; the first lower connecting plate and the first upper connecting plate are connected by a first connecting clamp, and the lower part of the first connecting clamp is rigidly connected to the first lower connecting plate, while the upper part of the first connecting clamp is rotatably connected to the first upper connecting plate; a jack is installed between the upper and lower support plates; during the connection and installation of the upper section of the steel column, the tilt angle and elevation position of the upper section of the steel column are adjusted by the extension and retraction of the jack and the operation of the crane; during adjustment, the jack is used as the rotational power, and the rotational connection position of the first connecting clamp and the first upper connecting plate is used as the rotation axis to achieve fine-tuning of the tilt angle of the upper section of the steel column, ensuring the accuracy of the connection and installation. The first connecting plate and the lower connecting plate are fixedly set, and the connecting screw holes of the first connecting plate, the upper connecting plate, and the lower connecting plate are also fixedly set. Therefore, the adjustment of the upper steel column is not very flexible, especially when it is necessary to adjust it laterally relative to the plane of rotation. Further optimization is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a more convenient and reliable solution for the initial fixing and adjustment of inclined steel columns during the connection process, addressing the shortcomings of the aforementioned background technology.

[0005] To achieve the above objectives, the present invention provides a sloping steel column splicing and installation structure, including a docking stabilizer and a bottom adjustment platform. The docking stabilizer is disposed at the bottom end of the upper sloping steel column and the top end of the lower sloping steel column, and the bottom adjustment platform is disposed at the bottom end of the lower sloping steel column.

[0006] The docking stabilizer is configured as an annular shape and sleeved on the lower inclined steel column or the upper inclined steel column. The docking stabilizer has an annular mounting groove for mounting bolts. The mounting bolts connect the docking stabilizer at the bottom of the upper inclined steel column and the docking stabilizer at the top of the lower inclined steel column.

[0007] The bottom adjustment platform is hinged to the bottom end of the lower inclined steel column, and the bottom adjustment platform drives the bottom end of the lower inclined steel column to adjust its displacement.

[0008] Furthermore, the docking stabilizer has a preset distance from the end edge of the upper inclined steel column or the lower inclined steel column, so that a gap is left between the docking stabilizers of the two when the upper inclined steel column and the lower inclined steel column are docked.

[0009] Furthermore, both the upper inclined steel column and the lower inclined steel column are equipped with at least two docking stabilizers, the phase angle of the docking stabilizers is less than 180 degrees, and the docking stabilizers of the upper inclined steel column and the docking stabilizers of the lower inclined steel column are set in a one-to-one correspondence.

[0010] Furthermore, the docking stabilizer is welded and fixed to the upper inclined steel column or the lower inclined steel column.

[0011] Furthermore, the bottom adjustment platform includes a base assembly, a middle seat assembly, and a top seat assembly. The middle seat assembly is slidably connected to the base assembly, and the top seat assembly is slidably connected to the middle seat assembly. The sliding direction of the middle seat assembly relative to the base assembly is perpendicular to the sliding direction of the top seat assembly relative to the middle seat assembly.

[0012] Furthermore, the base assembly includes a base plate, a base guide rail, and a base slider. The base guide rail is fixed to the base plate, and the base slider is slidably connected to the base guide rail. The intermediate seat assembly includes an intermediate seat plate, an intermediate seat guide rail, and an intermediate seat slider. The intermediate seat plate is fixedly connected to the base slider, the intermediate seat guide rail is disposed on the intermediate seat plate, and the intermediate seat slider is slidably connected to the intermediate seat guide rail. The top seat assembly includes a top seat plate, which is fixedly connected to the intermediate seat slider. A hinge is provided on the top seat plate, and the hinge is detachably connected to the bottom end of the lower inclined steel column.

[0013] Furthermore, the base plate is fixedly provided with a base threaded block, and the intermediate base plate is rotatably provided with an intermediate base adjusting screw, which is threadedly engaged with the base threaded block, and the direction of the intermediate base adjusting screw is consistent with the direction of the base guide rail; the intermediate base plate is fixedly provided with an intermediate base threaded block, and the top base plate is rotatably provided with a top base adjusting screw, which is threadedly engaged with the intermediate base threaded block, and the direction of the top base adjusting screw is consistent with the direction of the intermediate base guide rail.

[0014] The present invention also provides a method for splicing and installing inclined steel columns, which adopts the inclined steel column splicing and installation structure as described above, and includes the following steps:

[0015] S1, Install and weld stabilizers at the ends of the upper and lower inclined steel columns;

[0016] S2, according to the construction requirements, set measurement control points at the corresponding positions of the upper inclined steel column and the lower inclined steel column;

[0017] S3, hoisting the lower inclined steel column. The main lifting lugs are set at the non-end positions of the lower inclined steel column. The docking stabilizer at the top of the lower inclined steel column serves as an auxiliary lifting lug, used to attach the chain hoist and adjust the inclination and docking position of the lower inclined steel column.

[0018] S4. After the lower inclined steel column and the upper inclined steel column are initially connected, the installation bolt is inserted into the connection stabilizer, and the nut of the installation bolt is initially tightened to fix the lower inclined steel column and the upper inclined steel column initially. Then, the chain hoist of the auxiliary lifting lug is removed.

[0019] S5, use a total station to measure and correct the inclined steel column;

[0020] S6. Adjust the angle and position of the lower inclined steel column so that the measured coordinates of the docking position between the lower and upper inclined steel columns are consistent with the design coordinates, and then tighten the installation bolts further.

[0021] S7, weld and fix the joint between the lower inclined steel column and the upper inclined steel column.

[0022] Furthermore, in S6, when adjusting the lower inclined steel column, the position of the bottom end of the lower inclined steel column is adjusted synchronously through the bottom adjustment platform to adapt to the overall posture of the lower inclined steel column.

[0023] Furthermore, in S7, welding is performed from the gap between the upper and lower butt stabilizers, and simultaneously from both sides, to ensure uniform stress distribution during welding.

[0024] The above-described solution of the present invention has the following beneficial effects:

[0025] The inclined steel column splicing and installation structure and method provided by the present invention, by setting the end docking stabilizers of the upper inclined steel column and the lower inclined steel column, can improve the flexibility and operability of the tilt adjustment by relying on the stepless adjustment method during the adjustment of the lower inclined steel column, making it more reliable in the initial adjustment, and ensuring the docking accuracy of the inclined steel column after subsequent locking and welding fixation, thereby improving the quality of inclined steel column support construction.

[0026] In this invention, the bottom adjustment platform allows the bottom end of the lower inclined steel column to be hinged and supported, making it more stable during adjustment and preventing significant shaking, thus improving the reliability of hoisting operations.

[0037] like Figure 1 , Figure 2As shown, an embodiment of the present invention provides a sloping steel column splicing and installation structure, including a docking stabilizer 1 and a bottom adjustment platform 2. The docking stabilizer 1 is located at the bottom end of the upper sloping steel column 3 and the top end of the lower sloping steel column 4, while the bottom adjustment platform 2 is located at the bottom end of the lower sloping steel column 4. The docking stabilizer 1 at the bottom end of the upper sloping steel column 3 and the docking stabilizer 1 at the top end of the lower sloping steel column 4 are initially connected by mounting bolts 5. At this time, the mounting bolts 5 are not completely locked, allowing the lower sloping steel column 4 to adjust its docking angle and position relative to the upper sloping steel column 3. Simultaneously, the position of the bottom end of the lower sloping steel column 4 can also be adaptively adjusted during the adjustment process, which is more flexible than adjusting solely with slings. Furthermore, because the lower sloping steel column 4 is supported by the bottom adjustment platform 2, it is more stable during adjustment, less prone to large-scale swaying, and improves the reliability of the hoisting.

[0038] It should be noted that, in this embodiment, the following common scenario is used as an example: the upper horizontal beam has been fixed, and inclined steel columns need to be installed to further support the horizontal beam. The upper inclined steel column 3 is shorter than the lower inclined steel column 4. The upper inclined steel column 3 can be pre-fixed to the horizontal beam at a precise angle. After the horizontal beam is installed, only the lower inclined steel column 4 needs to be connected and fixed. Therefore, it is necessary to adjust the lower inclined steel column 4 to ensure precise connection with the upper inclined steel column 3.

[0039] In this embodiment, the docking stabilizer 1 is generally annular and has an annular mounting groove 6 for mounting bolts 5. The docking stabilizer 1 is installed at the bottom of the upper inclined steel column 3 and the top of the lower inclined steel column 4. Ideally, there should be a certain distance between the docking stabilizer 1 and the edge of the inclined steel column, so that after the upper inclined steel column 3 and the lower inclined steel column 4 are docked, there is a corresponding gap between the docking stabilizers 1. This gap allows space for the docking stabilizers 1 to adjust relative to the inclined steel columns, and also facilitates subsequent welding operations at the docking position (weld seam) of the inclined steel columns.

[0040] In a preferred embodiment, both the upper inclined steel column 3 and the lower inclined steel column 4 are equipped with two docking stabilizers 1. The phase angle of each docking stabilizer 1 is slightly less than 180 degrees, and the docking stabilizers 1 of the upper inclined steel column 3 and the lower inclined steel column 4 are correspondingly arranged. Using multiple docking stabilizers 1 facilitates the processing and installation of the docking stabilizers 1 themselves. The docking stabilizers 1 are directly welded and fixed to the surface of the inclined steel column.

[0041] Understandably, given that the docking stabilizer 1 is a ring-shaped device, it is more suitable for inclined steel columns with circular cross-sections, and can perfectly cover the ends of the inclined steel columns. For inclined steel columns with square cross-sections (such as I-shaped ones), the docking stabilizer 1 can also be fitted onto the ends of the inclined steel columns and fixed. In addition, the docking stabilizer 1 can also be set as an integral square structure with rounded corners to ensure its flexible adjustability.

[0042] Therefore, when using the docking stabilizer 1 provided in this embodiment, the lower inclined steel column 4 and the upper inclined steel column 3 can be initially docked, so that the docking stabilizers 1 at both ends are initially aligned. Then, the mounting bolts 5 are inserted into the mounting slots 6. The mounting bolts 5 pass through one mounting slot 6 into the other mounting slot 6 and out, and are then connected by nuts 7, so that the ends of the lower inclined steel column 4 and the upper inclined steel column 3 are initially fixed. At this time, the nuts are not fully tightened. Then, the docking deviation between the lower inclined steel column 4 and the upper inclined steel column 3 is detected and adjusted. During the adjustment of the lower inclined steel column 4, the relative position of the docking stabilizers 1 between the lower inclined steel column 4 and the upper inclined steel column 3 will change, that is, the position of the upper and lower mounting slots 6 may change. Since the mounting bolts 5 are not locked, their position can also be adjusted (manually or automatically). Under the premise that the mounting slots 6 are arc-shaped, the technical effect of stepless adjustment can be achieved. After the lower inclined steel column 4 is adjusted into place, tighten the mounting bolts 5 that have been adjusted to the most suitable position to determine the position of the lower inclined steel column 4 and the upper inclined steel column 3. Finally, weld the mating surfaces of the lower inclined steel column 4 and the upper inclined steel column 3 to fix them. This ensures the reliability and adjustability of the temporary connection of the lower inclined steel column 4 during the adjustment process, as well as the convenience of subsequent locking and fixing.

[0043] In a preferred embodiment, the docking stabilizer 1 is welded at a position 10cm away from the end of the inclined steel column, so that there is a gap of 20cm between the two corresponding docking stabilizers 1. The movable mounting bolts 5 are preferably six M24 10.9S steel structure large hexagonal high-strength bolts, and three mounting bolts 5 are grouped together and installed in the mounting groove 6 of the same group of docking stabilizers 1.

[0044] As mentioned earlier, after the lower inclined steel column 4 is initially connected to the upper inclined steel column 3 via the docking stabilizer 1, there is a further adjustment process. Existing methods typically rely solely on a crane chain hoist to adjust its posture until it meets installation requirements, or use jacks for assistance. This approach lacks flexibility, and given the considerable length of the lower inclined steel column 4, swaying is prone to occur during adjustment. This solution, through the further installation of the bottom adjustment platform 2, allows the bottom end of the lower inclined steel column 4 to be hinged and supported, resulting in greater stability during adjustment and preventing significant swaying, thus improving the reliability of the hoisting operation.

[0045] Specifically, in this embodiment, the bottom adjustment platform 2 includes a base assembly, a middle seat assembly, and a top seat assembly. The middle seat assembly is slidably connected to the base assembly, and the top seat assembly is slidably connected to the middle seat assembly. Furthermore, the sliding direction of the middle seat assembly relative to the base assembly is perpendicular to the sliding direction of the top seat assembly relative to the middle seat assembly. Therefore, the bottom end of the lower inclined steel column 4 has longitudinal and lateral translational freedom, allowing for flexible adjustment of the overall angle and position of the lower inclined steel column 4.

[0046] At the same time, such as Figure 3 As shown, in this embodiment, the base assembly includes a base plate 7, a base guide rail 8, and a base slider 9. The base guide rail 8 is fixed on the base plate 7, and the base slider 9 is slidably connected to the base guide rail 8. The intermediate seat assembly includes an intermediate seat plate 10, an intermediate seat guide rail 11, and an intermediate seat slider 12. The intermediate seat plate 10 is fixedly connected to the base slider 9, the intermediate seat guide rail 11 is disposed on the intermediate seat plate 10, and the intermediate seat slider 12 is slidably connected to the intermediate seat guide rail 11. The top seat assembly includes a top seat plate 13, which is fixedly connected to the intermediate seat slider 12. A hinge is provided on the top seat plate 13, which can connect to the bottom end of the lower inclined steel column 4, thereby hinged the bottom end of the lower inclined steel column 4 to the top seat plate. Preferably, the hinge is a lamp hook, which includes a locking part and a hooking part. The locking part can clamp the bottom end of the lower inclined steel column 4 as a detachable connection, while the hooking part is hinged to the top seat plate 13.

[0047] In this embodiment, the adjustment of the top plate 13 in two directions can also be achieved using screws, allowing the bottom end of the lower inclined steel column 4 to be reliably and stably displaced. Specifically, a base plate 7 (upper surface) is fixedly provided with a base threaded block, and a middle plate 10 (lower surface) is rotatably provided with a middle plate adjusting screw 15. The middle plate adjusting screw 15 is threadedly engaged with the base threaded block, and the direction of the middle plate adjusting screw 15 is consistent with the direction of the base guide rail 9. Therefore, when the middle plate adjusting screw 15 is turned, the middle plate 10 can move along the direction of the base guide rail 8. At the same time, a middle plate threaded block is fixedly provided on the middle plate 10 (upper surface), and a top plate adjusting screw 16 is rotatably provided on the top plate 13 (lower surface). The top plate adjusting screw 16 is threadedly engaged with the middle plate threaded block, and the direction of the top plate adjusting screw 16 is consistent with the direction of the middle plate guide rail 11. Therefore, when the top plate adjusting screw 16 is turned, the top plate 13 can move along the direction of the middle plate guide rail 11. During the adjustment of the lower inclined steel column 4, the top seat adjusting screw 16 and the intermediate seat adjusting screw 15 can be rotated to adapt the position of the top seat plate 13, i.e., the lower inclined steel column 4.

[0048] Other examples Figure 4As shown, a reinforcing brace 17 can be added to the middle of the lower inclined steel column 4. It is also a steel column or steel section. The top of the reinforcing brace 17 is hinged to the middle of the lower inclined steel column 4 through a lamp hook. Another bottom adjustment platform 2 is also set at the bottom of the reinforcing brace 17 so that the reinforcing brace 17 can adapt to the adjustment position of the lower inclined steel column 4 and further support the lower inclined steel column 4. A triangular support structure is formed at the bottom of the lower inclined steel column 4 to further improve the support stability.

[0049] Based on the same inventive concept, this embodiment also provides a method for splicing and installing inclined steel columns, which specifically includes the following steps:

[0050] S1, Install the docking stabilizer 1 at the ends of the upper inclined steel column 3 and the lower inclined steel column 4 and weld it in place.

[0051] S2. According to the construction requirements, set up measurement control points at the corresponding positions of the upper inclined steel column 3 and the lower inclined steel column 4.

[0052] S3, hoist the lower inclined steel column 4, wherein the main lifting lugs are set at the non-end positions of the lower inclined steel column 4, and more than one pair can be set, etc. The docking stabilizer 1 at the top of the lower inclined steel column 4 can be used as an auxiliary lifting lug to attach the chain hoist 18 and adjust the inclination and docking position of the lower inclined steel column 4.

[0053] S4. After the lower inclined steel column 4 and the upper inclined steel column 3 are initially connected, the installation bolt 5 is inserted into the connection stabilizer 1, and the nut of the installation bolt 5 is initially tightened to fix the lower inclined steel column 4 and the upper inclined steel column 3. Then the chain hoist 18 of the auxiliary lifting lug can be removed, while the sling 19 of the main lifting lug is not removed for the time being.

[0054] S5. Using a total station to measure and correct the inclined steel column, the elevation, axis position, and tilt angle of the inclined steel column can be measured and located using the three-dimensional coordinate measurement method. The measured data is compared with the design coordinates. Since this method is existing technology, the specific process will not be described in detail.

[0055] S6. Adjust the angle and position of the lower inclined steel column 4 so that the measured coordinates of the docking position between the lower inclined steel column 4 and the upper inclined steel column 3 are consistent with the design coordinates, and then tighten the installation bolts 5.

[0056] S7. Weld and fix the joint between the lower inclined steel column 4 and the upper inclined steel column 3 to complete the installation of the lower inclined steel column 4 and the upper inclined steel column 3.

[0057] In S4, when the lower inclined steel column 4 and the upper inclined steel column 3 are initially connected, the center lines of the lower inclined steel column 4 and the upper inclined steel column 3 are aligned and matched, and the edges are aligned as much as possible (for square steel columns, all four sides are taken into account). After inserting the mounting bolt 5 and placing it in the appropriate position in the mounting groove 6, the nut is initially tightened.

[0058] In S6, due to the mounting slot 6 of the docking stabilizer 1 and the fact that the mounting bolts 5 are not fully tightened, the mounting bolts 5 can be directly adjusted in position, allowing them to be tightened in the new position after adjustment. This ensures the secure installation of the lower inclined steel column 4 and the upper inclined steel column 3, providing stepless adjustment and better avoiding interference between the two docking stabilizers 1 during angle and position adjustments. Furthermore, when adjusting the lower inclined steel column 4, the position of its bottom end can be adjusted simultaneously to adapt to the overall posture of the lower inclined steel column 4. This is achieved by installing and controlling the bottom adjustment platform 2 (which needs to be removed at the end for further fixation and support of the bottom end of the lower inclined steel column 4).

[0059] In S7, welding is mainly carried out using carbon dioxide gas shielded welding. Based on the fact that two butt stabilizers 1 are set on both the upper inclined steel column 3 and the lower inclined steel column 4, two welders can simultaneously and symmetrically perform welding, operating through the gap between the two butt stabilizers 1 to ensure uniform distribution of welding stress.

[0060] In addition, after tightening the mounting bolts 5 and welding them in place, the coordinate position can be further confirmed using a total station to ensure that the lower inclined steel column 4 still meets the docking accuracy after the mounting bolts 5 are further tightened and welded in place, thus ensuring the reliability of the support.

[0061] It should be noted that the aforementioned upper inclined steel column 3 may also be located below the lower inclined steel column 4, meaning that the structure has multiple layers of intermediate beams and inclined steel columns. For the connection construction of the upper lower inclined steel column 4 and the lower upper inclined steel column 3, the bottom end of the lower inclined steel column 4 can be directly connected to the upper inclined steel column 3, without the need for further adjustment via the bottom adjustment platform 2.

[0062] In summary, the inclined steel column splicing and installation structure and method provided in this embodiment can be initially fixed while the upper inclined steel column 3 and the lower inclined steel column 4 are connected. The stepless adjustment method ensures the flexibility and operability of the tilt adjustment, making it more reliable during the initial adjustment. Subsequent locking and welding fixation ensure the connection accuracy of the inclined steel columns and improve the quality of the inclined steel column support construction.

[0063] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
