Description

Technical Field

[0001] This utility model belongs to the field of steel structure installation technology, and more specifically, it relates to a positioning structure suitable for steel beams and columns and a large-span steel structure factory building. Background Technology

[0002] With the rapid development of modern industry and warehousing needs, large-span steel structure workshops are widely used in large manufacturing workshops, logistics and warehousing centers, and other scenarios due to their advantages such as high space utilization, light structural weight, and short construction period. Large-span steel structure workshops typically consist of columns, beams, walls, and ceilings; the columns are connected by beams, and the ceiling mainly relies on steel beams for support. Therefore, the installation accuracy and stability of the steel beams directly affect the safety and service life of the workshop.

[0003] Currently, when installing crossbeams between columns, cranes are usually used for hoisting. In practice, the steel beams are first lifted vertically to the design height by the crane, and then the tilt angle and position of the steel beams are adjusted manually so that the steel beams are positioned between the two columns and the ends of the beams are in contact with at least one column. Finally, the connection between the ends of the steel beams and the columns is completed by welding, fasteners and other methods.

[0004] The inventors discovered that during the process of hoisting steel beams with a crane, the steel wire ropes used to connect to the steel beams are prone to swaying due to factors such as wind disturbance, crane start-stop inertia, or operational errors. This makes it difficult for the steel beams to remain stable in the air, requiring repeated adjustments to the connection and installation position between the steel beams and the columns, which in turn affects the installation efficiency of large-span steel structure workshops. Utility Model Content

[0005] The purpose of this application is to provide a positioning structure for steel beams and columns and a large-span steel structure factory building, so as to solve the technical problem that the steel beams are difficult to keep stable in the air during the existing process of using cranes to lift steel beams, which leads to a reduction in the installation efficiency of steel beams.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A positioning structure suitable for steel beams and columns is provided, comprising:

[0008] A lifting seat, for slidingly mounted on a column in a vertical direction, with a portion of the lifting seat located inside the column; and

[0009] A swing element is hinged to the lifting seat and located inside the column to support the bottom surface of the steel beam; the hinge axis of the swing element is parallel to the horizontal plane and perpendicular to the length direction of the steel beam, so that the side of the swing element can fit against the bottom surface of the steel beam.

[0010] The lifting seat is connected to a lifting drive mechanism; the swing member is connected to an angle adjustment mechanism, and the angle adjustment mechanism is used to drive the swing member to swing relative to the lifting seat.

[0011] In one possible implementation, the angle adjustment mechanism includes:

[0012] A first pulley is provided at the upper end of the column, and its rotation axis is parallel to the horizontal plane; and

[0013] A first traction rope is looped on the first pulley, and one end of the first traction rope is connected to the swing end of the swinging member, and the other end is connected to the first winch.

[0014] The first winch is fixed to the ground so that it can pull or release the first traction rope and cause the swinging member to swing when it is started.

[0015] In one possible implementation, the first traction rope has two parts;

[0016] The two first traction ropes are arranged side by side along the width direction of the swing member and are respectively connected to the two sides of the swing member facing its own width direction;

[0017] When the swing member supports the steel beam, the two first traction ropes are respectively located on both sides of the steel beam and are used to abut against the steel beam to restrict the movement of the steel beam toward the width direction of the swing member.

[0018] In one possible implementation, the oscillating element includes:

[0019] A fixed section, hingedly mounted on the lifting seat; and

[0020] The telescopic section is slidably disposed on the fixed section along the length direction of the fixed section;

[0021] The telescopic section is connected to a linear drive component, which drives the telescopic section to move relative to the fixed section; the telescopic section supports the steel beam, or the fixed section and the telescopic section support the steel beam simultaneously.

[0022] In one possible implementation, the fixed section has an internally hollow structure, and the telescopic section is slidably inserted into the interior of the fixed section, so that the extended portions of the fixed section and the telescopic section simultaneously support the steel beam.

[0023] In one possible implementation, the oscillating element further includes:

[0024] Multiple top plates are disposed on the upper side of the swing member and are spaced apart along the length of the swing member; each top plate has an adjustable distance structure with respect to the swing member, so that the top plate is adapted to move toward or away from the swing member;

[0025] The top plate is used to support the steel beam so that part or all of the steel beam is detached from the support surface of the swing member, thereby adjusting the angle between the steel beam and the swing member.

[0026] In one possible implementation, the adjustment structure includes:

[0027] A threaded hole is formed on the swing member; and

[0028] A screw is threaded into the threaded hole, and the upper end of the screw is hinged to the top plate.

[0029] In one possible implementation, the lifting drive mechanism includes:

[0030] A second pulley is provided at the upper end of the column, and its rotation axis is parallel to the horizontal plane; and

[0031] The second traction rope is looped on the second pulley, and one end of the second traction rope is connected to the lifting seat, and the other end is connected to the second winch;

[0032] The second winch is fixed to the ground so that it can pull or release the second traction rope when started, and move the lifting platform in the vertical direction.

[0033] In one possible implementation, the lifting seat has a through cavity extending along its height direction, and the lifting seat is used to be fitted onto the column so that the column is inserted into the through cavity; the lifting seat further includes:

[0034] Multiple guide wheels are spaced apart circumferentially within the cavity of the lifting seat; each guide wheel is rotatably connected to the inner wall of the cavity and is used to contact the outer wall of the column.

[0035] In this embodiment, the lifting seat is initially positioned at a certain starting height along the track inside the column, such as the lowest position or a preset standby position. The swinging component is connected to the lifting seat via a hinge shaft. At this time, the swinging component can be in a natural drooping state or at a preset initial angle and is not in contact with the steel beam.

[0036] When it is necessary to support a steel beam of a specific height, the lifting drive mechanism is activated, and the lifting seat is driven to slide along the vertical direction of the column through the transmission connection structure.

[0037] Part of the lifting platform's structure is located inside the column, ensuring its movement is stable and without deviation. Ultimately, the lifting platform is precisely positioned at the target height, matching the height of the upper side of the lifting platform with the bottom surface of the steel beam in the hoisting state.

[0038] After the lifting platform reaches the target height, the angle adjustment mechanism is activated, which drives the swinging component to swing around the hinge axis through the transmission connection structure. Due to the limitation of the hinge axis direction, the swinging plane of the swinging component is a vertical plane, and its side gradually rotates towards the bottom surface of the steel beam, eventually completely fitting with the bottom surface of the steel beam in the hoisting state.

[0039] After the side of the swing component is in contact with the bottom surface of the steel beam in the hoisting state, the angle of the swing component is adjusted by the angle adjustment mechanism, thereby adjusting the installation angle of the steel beam. Then, the angle adjustment mechanism locks the current angle of the swing component to ensure that the swing component will not swing unexpectedly due to the weight of the steel beam or external forces. At the same time, the lifting drive mechanism also locks the position of the lifting seat to maintain the height stability of the lifting seat, and finally achieves reliable support for the bottom surface of the steel beam.

[0040] When it is necessary to remove the support or adjust the position of the steel beam, the angle adjustment mechanism reverses the swing component, causing it to detach from the bottom surface of the steel beam and return to the initial angle; then the lifting drive mechanism reverses the action, driving the lifting seat to slide down the column to the initial position, completing the reset of the device.

[0041] The positioning structure for steel beams and columns provided in this application embodiment, compared with the prior art, achieves precise adjustment of the support height through the design of the lifting seat sliding up and down along the column and the cooperation of the lifting drive mechanism. It can adapt to the support needs of steel beams of different heights and improve the versatility of the device. The structure of the swing component hinged to the lifting seat with its hinge axis parallel to the horizontal plane and perpendicular to the length direction of the steel beam allows the side of the swing component to form surface contact support with the bottom surface of the steel beam, avoiding stress concentration problems caused by point contact or line contact and significantly improving the stability of the support. At the same time, the swing component is independently driven to swing through the angle adjustment mechanism, which can flexibly adapt to the bottom surface of the steel beam with different tilt angles. Combined with the height adjustment function of the lifting seat, it achieves dual precise control of height and angle, further expanding the applicable scenarios of the device. In addition, the layout design in which the lifting seat and the swing component are partially or entirely inside the column effectively optimizes the space occupation and makes the overall structure more compact and reasonable.

[0042] The technical solution adopted in this application also provides a large-span steel structure workshop, including the positioning structure applicable to steel beams and columns proposed in any of the foregoing.

[0043] The beneficial effects of the large-span steel structure workshop provided in this embodiment are the same as those of the aforementioned positioning structure applicable to steel beams and columns, and will not be repeated here. Attached Figure Description

[0055] Please refer to the following: Figures 1 to 4 The positioning structure applicable to steel beams and columns, and to large-span steel structure workshops provided in this application, are described below. The positioning structure applicable to steel beams and columns includes a lifting seat 1 and a swinging component 2.

[0056] The lifting seat 1 is used to slide on the column 7 in the vertical direction, and part of the lifting seat 1 is located inside the column 7.

[0057] The swing element 2 is hinged on the lifting seat 1 and located inside the column 7 to support the bottom surface of the steel beam 8. The hinge axis of the swing element 2 is parallel to the horizontal plane and perpendicular to the length direction of the steel beam 8 so that the side of the swing element 2 can fit against the bottom surface of the steel beam 8.

[0058] The lifting seat 1 is connected to the lifting drive mechanism 3; the swinging component 2 is connected to the angle adjustment mechanism 4, and the angle adjustment mechanism 4 is used to drive the swinging component 2 to swing relative to the lifting seat 1.

[0059] In this embodiment, the lifting seat 1 is initially at a certain starting height (such as the lowest position or the preset standby position) along the track inside the column 7. The swinging member 2 is connected to the lifting seat 1 through the hinge shaft. At this time, the swinging member 2 can be in a natural hanging state (or a preset initial angle) and does not contact the steel beam 8.

[0060] When it is necessary to support a steel beam 8 of a specific height, the lifting drive mechanism 3 (such as a motor + lead screw, hydraulic cylinder, etc.) is activated, and the lifting seat 1 is driven to slide along the vertical direction of the column 7 through the transmission connection structure (such as lead screw and nut pair, rack and pinion pair).

[0061] Part of the structure of the lifting seat 1 is located inside the column 7 (possibly limited by guide rails or slides) to ensure that its movement is stable and without deviation, and finally the lifting seat 1 is accurately positioned to the target height (matching the height of the bottom surface of the steel beam 8).

[0062] After the lifting seat 1 reaches the target height, the angle adjustment mechanism 4 (such as a servo motor + gear pair, electric push rod, etc.) is activated, and the swinging part 2 swings around the hinge axis through the transmission connection structure (the hinge axis is parallel to the horizontal plane and perpendicular to the length direction of the steel beam 8).

[0063] Due to the restriction of the hinge axis direction, the swing plane of the swinging component 2 is a vertical plane (perpendicular to the length direction of the steel beam 8). Its side gradually rotates towards the bottom surface of the steel beam 8, and finally completely fits into the bottom surface of the steel beam 8 (due to the design of the hinge axis direction, the contact between the side of the swinging component 2 and the bottom surface of the steel beam 8 is a surface contact, which makes the support more stable).

[0064] After the side of the swing component 2 is in contact with the bottom surface of the steel beam 8, the angle adjustment mechanism 4 locks the current angle of the swing component 2 (e.g., through a brake or self-locking transmission structure) to ensure that the swing component 2 will not swing unexpectedly due to the weight of the steel beam 8 or external forces; at the same time, the lifting drive mechanism 3 also locks the position of the lifting seat 1 (e.g., through screw self-locking or hydraulic cylinder pressure holding) to maintain the height stability of the lifting seat 1, and finally achieves reliable support for the bottom surface of the steel beam 8.

[0065] When it is necessary to remove the support or adjust the position of the steel beam 8, the angle adjustment mechanism 4 reverses the swing member 2, causing it to detach from the bottom surface of the steel beam 8 and return to the initial angle; then the lifting drive mechanism 3 reverses the action, driving the lifting seat 1 to slide down along the column 7 to the initial position, completing the reset of the device.

[0066] The positioning structure for steel beams and columns provided in this application, compared with the prior art, achieves precise adjustment of the support height through the design of the lifting seat 1 sliding up and down along the column 7 and the cooperation of the lifting drive mechanism 3. It can adapt to the support requirements of steel beams 8 of different heights, improving the versatility of the device. The structure of the swing member 2 hinged to the lifting seat 1 with its hinge axis parallel to the horizontal plane and perpendicular to the length direction of the steel beam 8 allows the side of the swing member 2 to form surface contact support with the bottom surface of the steel beam 8, avoiding stress concentration problems caused by point contact or line contact, and significantly improving the stability of the support. At the same time, the swing member 2 is independently driven to swing through the angle adjustment mechanism 4, which can flexibly adapt to the bottom surface of the steel beam 8 with different tilt angles. Combined with the height adjustment function of the lifting seat 1, it achieves dual precise control of height and angle, further expanding the applicable scenarios of the device. In addition, the layout design in which the lifting seat 1 and the swing member 2 are partially or entirely inside the column 7 effectively optimizes the space occupation, making the overall structure more compact and reasonable.

[0067] In some embodiments, the angle adjustment mechanism 4 described above can be as follows: Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The angle adjustment mechanism 4 includes a first pulley 41 and a first traction rope 42.

[0068] The first pulley 41 is used to be installed at the upper end of the column 7, and its rotation axis is parallel to the horizontal plane; the first pulley 41 can be a pulley group of multiple pulleys.

[0069] The first traction rope 42 is fitted onto the first pulley 41, and one end of the first traction rope 42 is connected to the swing end of the swing member 2, and the other end is connected to the first winch 43; the pulley has an embedding groove for the first traction rope 42 to be embedded.

[0070] The first winch 43 is fixed to the ground so that it can pull or release the first traction rope 42 when it is started, and cause the swing member 2 to swing.

[0071] The first winch 43 on the ground is started, and pulled or released by the first traction rope 42. After being turned by the first pulley 41, it drives the swinging member 2 to swing around the hinge axis, adjusting the contact angle between the swinging member 2 and the bottom surface of the steel beam 8.

[0072] The first winch 43 can be replaced with an electric push rod, which is directly connected to the swing end of the swing component 2. The angle can be controlled by the extension and retraction of the push rod, which is suitable for installation scenarios that require frequent small-amplitude angle adjustments.

[0073] The traction structure of winch and pulley enables remote control of the swing component at two angles, avoiding direct manual operation and reducing the risk of working at heights.

[0074] In some embodiments, the first traction rope 42 described above can be as follows: Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The first traction rope 42 has two ropes; the two first traction ropes 42 are arranged side by side along the width direction of the swing member 2 and are respectively connected to the two sides of the swing member 2 facing its own width direction.

[0075] When the swing member 2 supports the steel beam 8, the two first traction ropes 42 are located on both sides of the steel beam 8 and are used to abut against the steel beam 8 to restrict the movement of the steel beam 8 in the width direction of the swing member 2.

[0076] Two first traction ropes 42 are respectively connected to both sides of the swing member 2 in the width direction. When the swing member 2 supports the steel beam 8, the traction ropes naturally fit against both sides of the steel beam 8, restricting the steel beam 8 from shifting along the width direction of the swing member 2.

[0077] An elastic rubber pad is added at the contact point between the traction rope and the steel beam 8 to reduce friction damage, which is suitable for the installation of high-precision steel beams 8 whose surfaces are easily scratched.

[0078] The symmetrical arrangement of the two traction ropes not only enables angle adjustment, but also prevents the steel beam 8 from sliding laterally by abutting against the traction ropes, thus enhancing the stability of the steel beam 8's positioning.

[0079] In some embodiments, the aforementioned swing member 2 may be as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The swing member 2 includes a fixed section 21 and a telescopic section 22.

[0080] The fixed section 21 is hinged on the lifting seat 1.

[0081] The telescopic section 22 is slidably disposed on the fixed section 21 along the length direction of the fixed section 21.

[0082] The telescopic section 22 is connected to a linear drive component 5, which is used to drive the telescopic section 22 to move relative to the fixed section 21; the telescopic section 22 is used to support the steel beam 8, or the fixed section 21 and the telescopic section 22 are used to support the steel beam 8 simultaneously.

[0083] The telescopic section 22 is driven to slide along the length of the fixed section 21 by a linear drive component 5 (such as an electric push rod or a hydraulic cylinder), and the extension length of the telescopic section 22 is adjusted so that the fixed section 21 and the telescopic section 22 jointly support the steel beam 8, or the telescopic section 22 alone supports it.

[0084] Anti-slip teeth can be installed on the contact surfaces of the fixed section 21 and the telescopic section 22 to lock the position of the telescopic section 22, which is suitable for installation on heavy steel beams 8 that need to withstand large loads.

[0085] The adjustable length of the telescopic section 22 allows it to adapt to steel beams 8 of different lengths, thus expanding the applicability of the positioning structure.

[0086] In some embodiments, the fixed segment 21 described above can be adopted as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The fixed section 21 has an internally hollow structure, and the telescopic section 22 is slidably inserted into the interior of the fixed section 21 so that the extended parts of the fixed section 21 and the telescopic section 22 can simultaneously support the steel beam 8.

[0087] A guide groove can be set inside the fixed section 21, and a matching guide block can be set on the outside of the telescopic section 22 to reduce sliding resistance. This is suitable for installation scenarios that require frequent adjustment of the telescopic length.

[0088] The hollow fixed section 21 can reduce its own weight, while the nested design of the telescopic section 22 and the fixed section 21 enhances the overall rigidity and avoids structural deformation caused by excessive cantilever length.

[0089] In some embodiments, the aforementioned swing member 2 may be as follows: Figures 2 to 4 The structure shown is described in the following document. Figures 2 to 4 The swing element 2 also includes multiple top plates 23.

[0090] Multiple top plates 23 are disposed on the upper side of the swing member 2 and are arranged at intervals along the length direction of the swing member 2; each top plate 23 has an adjustment structure 6 between it and the swing member 2 so that the top plate 23 is suitable for moving toward or away from the swing member 2.

[0091] The top plate 23 is used to support the steel beam 8 so that part or all of the steel beam 8 is separated from the support surface of the swing member 2, thereby adjusting the angle between the steel beam 8 and the swing member 2.

[0092] By adjusting the distance between multiple top plates 23 and the swinging component 2 through the adjustment structure 6, some of the top plates 23 are lifted to raise the steel beam 8, changing the angle between the steel beam 8 and the support surface of the swinging component 2, thereby achieving a fine adjustment of the tilt angle of the steel beam 8.

[0093] The top plate 23 can be replaced with a ball head structure, which adapts to the curved shape of the bottom surface of the steel beam 8 through spherical contact, and is suitable for positioning the arc-shaped steel beam 8.

[0094] The support height of the steel beam 8 can be locally adjusted by the independently adjustable top plate 23, which solves the problem of the steel beam 8 not fitting properly with the support surface due to processing errors or installation deviations.

[0095] In some embodiments, the above-described adjusting structure 6 can be adopted as follows: Figures 2 to 4 The structure shown is described in the following document. Figures 2 to 4 The adjustable pitch structure 6 includes a threaded hole 61 and a screw 62.

[0096] A threaded hole 61 is provided on the swing member 2; a screw 62 is threaded into the threaded hole 61, and the upper end of the screw 62 is hinged to the top plate 23.

[0097] By rotating the screw 62, it can move up and down within the threaded hole 61 of the swing member 2, thereby driving the top plate 23 to rise and fall, and adjusting the distance between the top plate 23 and the swing member 2.

[0098] A handwheel can be added to the lower end of the screw 62 for easy manual rotation and adjustment, or the screw 62 can be replaced with a servo motor to achieve automated and precise distance adjustment, which is suitable for high-precision installation scenarios.

[0099] The threaded adjustment structure 6 is easy to operate and has self-locking properties. After adjustment, the position of the top plate 23 is stable and no additional locking is required.

[0100] In some embodiments, the lifting drive mechanism 3 described above can be as follows: Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The lifting drive mechanism 3 includes a second pulley 31 and a second traction rope 32.

[0101] The second pulley 31 is used to be installed at the upper end of the column 7, and its rotation axis is parallel to the horizontal plane.

[0102] The second traction rope 32 is fitted onto the second pulley 31, and one end of the second traction rope 32 is connected to the lifting seat 1, while the other end is connected to the second winch 33.

[0103] The second winch 33 is fixed to the ground so that it can pull or release the second traction rope 32 when it is started, and move the lifting seat 1 in the vertical direction.

[0104] Start the second winch 33 on the ground, pull or release it through the second traction rope 32, and after turning through the second pulley 31, drive the lifting seat 1 to slide up and down along the column 7, and adjust the steel beam 8 to the target height.

[0105] The second winch 33 can be replaced with a drum driven by a stepper motor. The length of the traction rope can be precisely controlled by an encoder to achieve millimeter-level height adjustment of the lifting seat 1, which is suitable for precision installation requirements.

[0106] The hoisting structure of the winch and pulley enables remote control of the height of the lifting platform 1, avoiding high-altitude operations, and the flexible connection of the traction rope can adapt to the slight swaying of the column 7.

[0107] In some embodiments, the lifting seat 1 described above may adopt the following... Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The lifting seat 1 has a through cavity extending along its height direction, and the lifting seat 1 is used to fit onto the column 7 so that the column 7 is inserted into the through cavity; the lifting seat 1 also includes a plurality of guide wheels 11.

[0108] Multiple guide wheels 11 are spaced apart in the cavity along the circumference of the lifting seat 1; each guide wheel 11 is rotatably connected to the inner wall of the cavity and is used to connect with the outer wall of the column 7.

[0109] The lifting seat 1 is fitted onto the column 7 through a cavity. The guide wheel 11 inside the cavity contacts the outer wall of the column 7. When the lifting seat 1 slides, the guide wheel 11 rolls along the column 7 to reduce frictional resistance.

[0110] The guide wheel 11 can be replaced with a friction-reducing slider (such as a PTFE slider), which reduces costs and eliminates the need for lubrication, making it suitable for construction environments with high dust levels.

[0111] The guide wheel 11 makes the sliding of the lifting seat 1 and the column 7 smoother, avoids jamming caused by excessive contact area, and at the same time distributes the load and extends the service life of the structure.

[0112] The detailed working steps for the positioning structure applicable to steel beams and columns proposed in this application are as follows:

[0113] Step 1: Adjust the initial position of the lifting seat 1:

[0114] First, based on the target installation height of the steel beam 8, the lifting drive mechanism 3 (second winch 33 + second traction rope 32 system, or other drive methods such as hydraulic cylinders) is activated. The lifting drive mechanism 3 drives the lifting seat 1 to slide along the vertical direction of the column 7 through the transmission connection; the second winch 33 pulls the second traction rope 32 (which is deflected via the second pulley 31), causing the lifting seat 1 to move upward along the column 7; if the second winch 33 releases the traction rope, the lifting seat 1 will slide downward due to its own weight or the auxiliary mechanism. During this process, the through cavity of the lifting seat 1 is placed outside the column 7, and the guide wheel 11 inside the through cavity rolls in contact with the outer wall of the column 7, ensuring that the lifting seat 1 slides smoothly and avoids jamming or deviation, and finally adjusts the lifting seat 1 to a position that matches the installation height of the steel beam 8.

[0115] Step 2: Pre-adjustment of the angle of the oscillating component 2:

[0116] After the lifting platform 1 reaches the target height, the angle adjustment mechanism 4 is activated (first winch 43 + first traction rope 42 system, or other adjustment methods such as electric push rod). Since the swinging component 2 is hinged to the lifting platform 1, and the hinge axis is parallel to the horizontal plane and perpendicular to the length direction of the steel beam 8 (i.e., the hinge axis is horizontal and perpendicular to the front and rear extension direction of the steel beam 8), the angle adjustment mechanism 4, through the transmission connection (the first winch 43 pulls the first traction rope 42, which is turned by the first pulley 41 and then acts on the swinging end of the swinging component 2), drives the swinging component 2 to swing around the hinge axis in the vertical plane (the swinging direction is up and down or front and back tilt). The purpose of this step is to adjust the angle of the support surface of the swinging component 2 in advance according to the tilt angle of the bottom surface of the steel beam 8 (such as the slope required by the design or the installation deviation), so that its side (i.e., the upper surface) is consistent with the theoretical contact angle of the bottom surface of the steel beam 8.

[0117] Step 3: Erection and temporary support of steel beam 8:

[0118] The steel beam 8 is hoisted to the top of the column 7 using external hoisting equipment (such as a crane) and then slowly lowered onto the support surface of the swing member 2. At this point, the upper side of the swing member 2 has been adjusted to fit against the bottom surface of the steel beam 8, forming initial support. Since the swing member 2 is located inside the column 7 (i.e., near the center of the column 7), its support position is close to the connection node between the steel beam 8 and the column 7, which can effectively disperse the bending moment of the steel beam 8 on the column 7 and reduce the risk of instability during hoisting.

[0119] Step 4: Precise positioning and final fixation:

[0120] After the steel beam 8 contacts the swing element 2, the lifting drive mechanism 3 and the angle adjustment mechanism 4 are finely adjusted again: if the height of the steel beam 8 needs slight correction, the height of the lifting seat 1 is slightly adjusted through the lifting drive mechanism 3; if the bottom surface of the steel beam 8 is not tightly attached to the swing element 2 (e.g., due to processing errors), the angle of the swing element 2 is finely adjusted through the angle adjustment mechanism 4 until the bottom surface of the steel beam 8 is completely attached to the side of the swing element 2. At this point, the horizontal position, height, and tilt angle of the steel beam 8 are precisely positioned through the coordinated adjustment of the lifting seat 1 and the swing element 2. Subsequently, the steel beam 8 can be finally fixed to the column 7 through welding, bolt connection, or other methods to complete the installation.

[0121] Step 5: Reset the positioning structure:

[0122] If the positioning structure needs to be reused, after the steel beam 8 is fixed, the swinging part 2 is driven in the opposite direction by the angle adjustment mechanism 4 (such as releasing the first traction rope 42) to make it detach from the bottom surface of the steel beam 8; then the lifting drive mechanism 3 slides the lifting seat 1 to the initial low position to prepare for the next installation of the steel beam 8.

[0123] This positioning structure achieves precise positioning of the steel beam 8 and the column 7 through dual-dimensional control of "height adjustment of lifting seat 1 + angle adjustment of swing component 2". It is especially suitable for complex installation scenarios that require adjustment of height or tilt angle, and significantly improves the efficiency and accuracy of steel structure installation.

[0124] The technical solution adopted in this application also provides a large-span steel structure workshop, including the positioning structure applicable to steel beams and columns proposed in any of the preceding claims.

[0125] This positioning structure can be adapted to the installation requirements of large-span steel beams 8. By adjusting the height, angle, length and other dimensions, it solves the problem of positioning difficulties caused by large spans in traditional installation and improves the stability of the overall structure of the factory building. This positioning structure can be applied to double-layer or multi-layer steel structure factory buildings. Through the coordinated adjustment of multi-layer lifting seats 1, the synchronous installation of steel beams 8 with different floor heights can be achieved, thereby improving construction efficiency.

[0126] The beneficial effects of the large-span steel structure workshop provided in this embodiment are the same as those of the aforementioned positioning structure applicable to steel beams and columns, and will not be repeated here.

[0127] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
