Description

Technical Field

[0001] This utility model relates to the field of hoisting structure technology, specifically to an adaptive stabilizing steel beam hoisting structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The hoisting of I-beams is unavoidable. Conventional hoisting methods generally use steel cables, hoisting holes, and lifting lugs.

[0003] However, the following problems may arise during hoisting using steel cables: the steel cables may damage the surface of the I-beam, requiring subsequent repainting; inadequate repainting may result in rust. Additionally, since the steel cables are only positioned by the structure of the beam when tied to the outside of the beam, they will move back and forth due to swaying during hoisting. The friction between the tied steel cables and the edge of the beam during movement will cause wear on the cables, leading to a decrease in cable strength and potential safety hazards.

[0004] If lifting holes are used, holes need to be drilled in the flanges of the I-beam. The location of the holes must meet the lifting requirements and not affect the structure itself. If lifting lugs are used, they need to be welded to the flanges of the I-beam. For some I-beams located between floors, the lifting lugs need to be cut off after lifting, which is labor-intensive and may damage the base material. Furthermore, construction workers suspended on the steel beam cutting the lugs must pay attention to their own safety and avoid damaging the steel beam, posing certain safety hazards. Therefore, we propose an adaptive stabilizing steel beam lifting structure. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive stabilizing steel beam hoisting structure, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Adaptive stabilizing steel beam hoisting structure, including steel beams and columns;

[0008] The steel beams and columns are equipped with suspension mechanisms, and the steel beams are equipped with adjustment mechanisms in the middle.

[0009] Both suspension mechanisms include a fixing block, which is a ring structure. The two fixing blocks are respectively sleeved on the outer ends of the steel beam and the top of the column. A lifting lug is fixedly connected to the outer side of the fixing block.

[0010] Preferably, each suspension mechanism has two lugs, which are symmetrically connected to the side edge of the fixing block, and a reinforcing plate is fixedly connected between the two lugs.

[0011] Preferably, the adjustment mechanism includes an adjustment block, which is sleeved in the middle of the steel beam, and a positioning plate is connected to the bottom end of the adjustment block.

[0012] Preferably, the positioning plate is connected to a fastening bolt, which passes through the adjusting block and the positioning plate respectively, and a nut is sleeved on the outside of the fastening bolt.

[0013] Preferably, the adjusting block has a mounting hole on its side, the mounting hole is a strip-shaped structure, and the width of the mounting hole is the same as the diameter of the fastening bolt.

[0014] Preferably, a filling block is movably connected to the side of the adjusting block. The filling block has a wedge-shaped structure, and a groove corresponding to the fastening bolt structure is opened on the inner side of the filling block.

[0015] Preferably, a second lifting lug is fixedly connected to the top of the adjusting block, and a connecting buckle is movably connected to both the first and second lifting lugs.

[0016] By employing the above technical solution, this utility model provides an adaptive stabilizing steel beam hoisting structure that has at least the following beneficial effects:

[0017] (1) This utility model adopts a non-destructive installation method using annular fixing blocks, that is, using annular fixing blocks fitted onto both ends of the steel beam and the top of the column, replacing the traditional method of welding lifting lugs. The fixing block is a split welded structure, which fits against the surface of the steel beam through annular fitting, eliminating the need to drill holes or weld on the steel beam, thus avoiding damage to the base material. After hoisting, the fixing block can be directly cut, leaving a gap between the cut surface and the surface of the steel beam to avoid damaging the base material, thus solving the problem of easy damage to the steel beam when cutting traditional lifting lugs. The fixing block disperses hoisting stress by increasing the contact area, reducing the local pressure on the steel beam, and is suitable for steel beam structures with complex cross-sections such as I-beams. The externally mounted lifting lug structure of this utility model allows the fixing block to cooperate with the structure at both ends of the steel beam or the top of the column. While positioning the fixing block, it can also make the fixing block and the steel beam independent of each other, facilitating the cutting and removal of the fixing block after the steel beam is hoisted.

[0018] (2) This utility model adopts a stable design with double lifting lugs and reinforcing plates. Symmetrical double lifting lugs are set on the outer side of each fixing block, and the reinforcing plates are cross-connected to form a triangular stable structure. The double lifting lug design balances the force on the steel cable and suppresses the torsional swaying during the hoisting of the steel beam. Compared with the traditional single lifting lug, the anti-rotation stability is improved by more than 50%. The reinforcing plates enhance the structural strength of the lifting lug connection, disperse stress concentration, and reduce the risk of lifting lug breakage.

[0019] (3) This utility model adopts a sliding adjustable block for center of gravity adaptation. The adjustable block is set in the middle of the steel beam, and the sliding positioning of the adjustable block on the steel beam is achieved through the cooperation of the strip-shaped mounting hole and the fastening bolt. The positioning plate at the bottom of the adjustable block adapts to the tilt angle of the bottom surface of the steel beam through the wedge-shaped filling block. The auxiliary suspension point can be dynamically adjusted according to the center of gravity position of the steel beam to make the steel cable bear the force evenly and avoid the wear of the steel cable on one side due to the offset of the center of gravity. This utility model is applicable to steel beams of different lengths and cross sections, without the need for customized lifting lugs, improving versatility and reducing construction preparation time. The auxiliary suspension point of the adjustable structure of this utility model can adjust the position of the adjustable block on the steel beam, thereby allowing the center of gravity to be freely adjusted, improving the uniformity of the force on the steel cable and avoiding damage to the steel cable caused by uneven force.

[0020] (4) This utility model uses wedge-shaped filler blocks for angle compensation. A wedge-shaped filler block is provided on the side of the adjusting block, and its inner groove cooperates with the fastening bolt to fill the angular gap between the adjusting block and the bottom surface of the steel beam. This ensures that the adjusting block is tightly fitted to the bottom surface of the steel beam. Even if the bottom surface of the steel beam is tilted, vertical force can be applied through the wedge structure, improving suspension stability (effective fixation can still be maintained when the tilt angle is ≤15°). This utility model simplifies the installation process, eliminates the need for precise alignment, and meets the rapid installation needs of construction sites. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Adaptive stabilizing steel beam hoisting structure, such as Figure 1 , Figure 2 , Figure 5 As shown, it includes a steel beam 1 and a column 2; the steel beam 1 and the column 2 are equipped with a suspension mechanism 3, which allows construction personnel to easily install steel cables on the steel beam 1 or the column 2, thereby lifting and moving the steel beam 1 or installing safety ropes through the steel cables to protect construction personnel working at height.

[0031] Specifically, both suspension mechanisms 3 include fixing blocks 31, which are ring-shaped structures. Two fixing blocks 31 are respectively fitted onto the outer ends of the steel beam 1 and the top of the column 2. The fixing blocks 31 are formed by welding two components together. This increases the strength of the suspension point while reducing damage to the main structure of the steel beam 1. During lifting, the increased contact area between the force-applying structure and the steel beam 1 reduces the pressure on the steel beam 1 structure. Furthermore, the fitted structure can be removed by cutting after construction. Compared to the traditional method of directly cutting the lifting lugs from the steel beam 1 structure, the fixing blocks 31 reduce damage to the main structure of the steel beam 1 during cutting. Since part of the steel beam 1 structure is I-beam, there is a gap between the side of the steel beam 1 and the fixing blocks 31. When cutting and removing the fixing blocks 31, protective structures can be filled into the gaps, allowing construction workers to work at heights without worrying about cutting errors caused by swaying, thus improving worker safety and operational efficiency. The fixing blocks 31 on the column 2 can serve as connection points for safety ropes, further enhancing the safety protection for construction workers.

[0032] In addition, a lifting lug 32 is fixedly connected to the outside of the fixed block 31. Each suspension mechanism 3 has two lifting lugs 32, which are symmetrically connected to the side edge of the fixed block 31. A reinforcing plate 33 is fixedly connected between the lifting lugs 32, and a connecting buckle 34 is movably connected to the lifting lug 32. The combination of the double lifting lug 32 structure and the cross-connected reinforcing plate 33 can improve the safety performance of the steel cable when suspending the steel beam 1. Compared with the traditional single lifting lug structure, the traditional lifting lug will be subjected to continuous torsion due to the reciprocating rotation and swaying caused by the steel beam 1 being affected by the vibration of operation or the airflow at a high position, which poses a certain risk. The combination of the double lifting lug 32 structure and the cross-connected reinforcing plate 33 can form multiple triangular structures at the connection of the connecting buckle 34, which can distribute the force of the suspension point to the entire fixed block 31, thereby improving the stability of the lifting lug 32.

[0033] Example 2

[0034] like Figures 1-4 As shown, based on Embodiment 1, the steel beam 1 is provided with an adjustment mechanism 4 in the middle; the adjustment mechanism 4 can increase the suspension point through the auxiliary structure, so that the position of the auxiliary suspension can be adjusted when different steel beams 1 are suspended, thereby adapting to different suspension requirements and the safety protection requirements of construction personnel in different positions.

[0035] In this embodiment, the adjustment mechanism 4 includes an adjustment block 41, which is sleeved in the middle of the steel beam 1. A positioning plate 42 is connected to the bottom end of the adjustment block 41. The positioning plate 42 is movably connected to the inner side of the adjustment block 41 and combines with the adjustment block 41 to form a ring structure to support the middle of the steel beam 1. At the same time, the adjustment plate structure can be adjusted to adapt to the support of the bottom of the steel beam 1 at different angles.

[0036] Based on this, fastening bolts 43 are connected to the positioning plate 42. The fastening bolts 43 pass through the adjusting block 41 and the positioning plate 42 respectively. Nuts 44 are fitted onto the outside of the fastening bolts 43, allowing them to cooperate with the nuts 44 to secure the positioning plate 42 and the adjusting block 41. The adjusting block 41 has mounting holes 45 on its side. These holes are strip-shaped, with a width equal to the diameter of the fastening bolts 43. The strip-shaped mounting holes 45 can accommodate different tilt angles for installation. A filler block 46 is movably connected to the side of the adjusting block 41. The filler block 46 has a wedge-shaped structure, which eliminates the angle difference between the fastening bolts 43 and the adjusting block 41, thereby improving the stability between the positioning plate 42 and the adjusting block 41. The inner side of the filler block 46 has a groove 47 corresponding to the structure of the fastening bolts 43, facilitating the installation of the filler block 46.

[0037] Furthermore, a second lifting lug 48 is fixedly connected to the top of the adjusting block 41, and a connecting buckle 34 is movably connected to the second lifting lug 48. The connecting buckle 34 structure can assist in suspending the steel beam 1 through the second lifting lug 48 and the adjusting block 41, thereby improving the stability of suspending and transporting the steel beam 1 structure. At the same time, when the steel cable is connected to the steel beam 1 through the connecting buckle 34, different suspension methods can be used through the structure at the bottom of the steel beam 1, so that the force direction at the suspension point of the adjusting block 41 is close to perpendicular to the slope angle at the bottom of the steel beam 1, thereby improving safety performance.
