Description

Technical Field

[0001] The invention relates to the technical field of steel structure column assembly, and in particular to a safety device and method for installing high-rise assembled steel structure columns. Background Art

[0002] The assembly of steel structure columns can realize fast, standardized and green construction of buildings, improve construction quality and efficiency, and promote the industrialization and modernization of buildings. In modern buildings, steel structures are widely used due to their many advantages. Through factory prefabrication and rapid on-site assembly, the construction period can be significantly shortened, on-site operations can be reduced, and environmental impact can be reduced. When assembling steel structure columns, it is necessary to pay attention to a series of key issues such as pre-construction preparation, hoisting and installation, connection and correction.

[0003] Therefore, based on the existing, when assembling steel structure columns, workers climb from the outside of the steel structure columns to the assembly location, then use a crane to lift the steel plate to the assembly location, and then use bolts to connect the steel plate to the steel structure column. However, it is difficult to stably control the steel plate at the assembly location by using a crane. During the connection process, workers are usually required to work with both hands at a high altitude and pay attention to whether the steel plate moves in real time, which poses a great safety hazard. In addition, the surface of the steel structure column is usually smooth. In the event of an emergency, there is basically no place to grab, which greatly increases the work risk. In addition, during the installation of the steel structure column, if the lifting equipment is improperly operated or the lifting point is unreasonably set, it may cause uneven force on the steel column, resulting in stress concentration, thereby causing the connection hole or bolt to crack. For this reason, we propose a safety device and method for the installation of high-rise assembled steel structure columns. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a safety device and method for installing high-rise assembled steel structure columns.

[0033] In a typical implementation of the present application, Figure 1-9 As shown, a safety device and method for installing a high-rise assembled steel structure column includes:

[0034] Steel frame 1, the steel frame 1 is used to support the building structure, the steel frame 1 includes a main steel column plate 6 fixed to the ground, one side of the main steel column plate 6 is fixedly connected with an assembly plate 7, one side of the main steel column plate 6 is suspended with a connecting steel plate 8, and the assembly plate 7 and the connecting steel plate 8 are assembled by bolting;

[0035] The climbing device 2 is used to improve the construction safety of workers when they fix the connecting steel plate 8 on the outside of the main steel column plate 6, and improve the construction efficiency. The climbing device 2 includes a climbing shell 10 arranged on the outside of the main steel column plate 6, and two first permanent magnets 11 are slidably installed inside the climbing shell 10. The two first permanent magnets 11 are adsorbed on one side of the main steel column plate 6. A universal structure is provided on one side of the climbing shell 10. Specifically, human magnetic climbing usually adopts the first permanent magnet 11, especially neodymium iron boron permanent magnet material, which can ensure the stable movement of the climbing equipment or robot on the metal surface.

[0036] The universal structure includes a placement bag fixedly connected to both sides of the climbing shell 10, which is used to place the connecting bolts or other required tools required for the steel structure 1. One side of the climbing shell 10 is fixedly connected to a limiting sleeve 9, and the inner sliding connection of the limiting sleeve 9 is connected to a slide cylinder 41. One side of the limiting sleeve 9 is threadedly screwed with a fixing bolt 50, and one end of the fixing bolt 50 abuts against the outside of the slide cylinder 41. The top damping rotation connection of the slide cylinder 41 is connected to a rotating shaft 42, and the top damping rotation connection of the rotating shaft 42 is connected to a damping telescopic rod 43. The extended end of the damping telescopic rod 43 is connected to an adjusting block 44. One end of the adjusting block 44 is fixedly connected to a magnetic plate 45, and the outer surface of the magnetic plate 45 can adsorb bolts, nuts or other tools used for connecting the steel structure 1.

[0037] By setting up the above-mentioned mechanism, the physical exertion of workers climbing the main steel column plate 6 can be reduced, and the safety of workers climbing the main steel column plate 6 can be improved. Specifically, when the workers move to the assembly site, the required parts and tools are adsorbed on the outside of the magnetic plate 45, and the slide tube 41 is pulled out to adjust the magnetic plate 45 to a suitable height, and then the slide tube 41 is fixed by screwing the fixing bolts 50, and then the magnetic plate 45 is rotated around the top of the rotating shaft 42 to make a second adjustment to the height of the magnetic plate 45. The movement of the magnetic plate 45 drives the rotating shaft 42 to rotate at the top of the slide tube 41, and the damping telescopic rod 43 is pulled out to adjust the magnetic plate 45 to a suitable position. After the final adjustment of the magnetic plate 45 is completed, it is convenient for workers to take and use the parts and tools.

[0038] A positioning device 5 is plugged at the connection between the assembly plate 7 and the connecting steel plate 8. The positioning device 5 includes a double-threaded rod 46. The external threads of the double-threaded rod 46 are screwed with two sliding blocks 47. The two sliding blocks 47 are symmetrically arranged. The external part of the sliding block 47 is rotatably connected to a driven plate 48. One end of the two driven plates 48 on the same side is rotatably clamped with the same expansion bar 49. One side of the double-threaded rod 46 is fixedly connected with a twist 51. The external part of the expansion bar 49 is simultaneously in contact with the internal part of the assembly plate 7 and the connecting steel plate 8. The separated sides of the two crawler frames 28 are fixedly connected to the limit plate 31. The interior of the climbing shell 10 is fixedly connected to two limit columns 30. The two limit plates 31 are respectively slidably connected to the outside of the adjacent limit columns 30. The interior of the climbing shell 10 is fixedly connected to two magnetic baffles 40. The two spring steel plates 22 are both slidably connected to the top of the adjacent magnetic baffles 40.

[0039] By setting the above-mentioned mechanism, the connection between the assembly plate 7 and the connecting steel plate 8 can be docked, and the bolts of the assembly plate 7 and the connecting steel plate 8 can be protected to prevent stress cracking caused by unstable movement of the connecting steel plate 8. Specifically, the positioning device 5 is inserted into the connection between the assembly plate 7 and the connecting steel plate 8, and one of the expansion bars 49 is held to rotate the twist 51. The rotation of the twist 51 drives the double-threaded rod 46 to rotate. The rotation of the double-threaded rod 46 drives the two sliding blocks 47 to gradually approach each other. The two sliding blocks 47 gradually approach each other and drive the corresponding driven plates 48 Move, the driven plate 48 moves and drives the corresponding expansion strip 49 to move, so that the four expansion strips 49 gradually expand, and the assembly plate 7 and the connecting steel plate 8 are gradually weighed to ensure the accuracy of the position. In addition, multiple positioning devices 5 can be inserted for support to ensure the stability of the connection between the assembly plate 7 and the connecting steel plate 8. When the assembly plate 7 and the connecting steel plate 8 are subjected to excessive force and shake, the expansion strip 49 breaks to protect the assembly plate 7 and the connecting steel plate 8, avoid damage to the assembly plate 7 and the connecting steel plate 8, and increase the service life of the assembly plate 7 and the connecting steel plate 8.

[0040] The adsorption device 3 is used to change the adsorption force of the climbing device 2 on the surface of the main steel column plate 6, so as to facilitate the workers to move the climbing device 2. Two driving grooves 24 are provided on one side of the climbing shell 10. A second permanent magnet 25 is slidably installed inside the driving groove 24. The second permanent magnet 25 is fixedly sleeved with a second protective shell 26 on the outside. The second protective shell 26 is rotatably sleeved with a crawler 27 on the outside. The outside of the crawler 27 abuts against the outside of the main steel column plate 6. The adsorption device 3 also includes a rotating motor 14 fixedly installed at the bottom of the inner wall of the climbing shell 10. The output end of the rotating motor 14 is rotatably connected to a driving gear 15. The climbing shell 10 is rotatably connected to a rotating shaft 16 inside. A driven gear ring 17 is fixedly sleeved on the outside of the rotating shaft 16. The driving gear 15 and the driven gear ring 17 are rotatably sleeved with the same chain 18. The top of the rotating shaft 16 is fixedly sleeved with a first spiral pattern 19.

[0041] The external thread of the first spiral pattern 19 is screwed with a slider 21, the external part of the first permanent magnet 11 is fixedly sleeved with the first protective shell 12, the top of the first protective shell 12 is fixedly connected to the connecting frame 13, the top of the connecting frame 13 is rotatably connected to the spring steel plate 22, the opposite ends of the two spring steel plates 22 are fixedly connected to the slider 21, the top of the spring steel plate 22 is bonded with a strain gauge 23, the external part of the second protective shell 26 is fixedly connected to a frame 28, the opposite sides of the two frames 28 are fixedly connected to the same connecting plate 29, the bottom of the rotating shaft 16 is fixedly sleeved with the second spiral pattern 20, and the connecting plate 29 is screwed on the outside of the second spiral pattern 20.

[0042] By setting the above-mentioned mechanism, the safety of the workers can be guaranteed and the physical energy consumption of the workers can be reduced. Specifically, the climbing shell 10 is first adsorbed on the outside of the main steel column plate 6. When the worker is climbing, the rotating motor 14 is started, and the output end of the rotating motor 14 rotates to drive the driving gear 15 to rotate, and the driving gear 15 rotates to drive the chain 18 to rotate, and the chain 18 rotates to drive the driven gear ring 17 to rotate, and the driven gear ring 17 rotates to drive the rotating shaft 16 to rotate, and the rotating shaft 16 rotates to drive the slider 21 to move, and the movement of the slider 21 drives the two spring steel plates 22 to move, and the movement of the two spring steel plates 22 drives the two first permanent magnets 11 to gradually move away from the main steel column plate 6 At the same time, the rotation of the rotating shaft 16 drives the connecting plate 29 to move outside the second spiral pattern 20, the movement of the connecting plate 29 drives the crawler frame 28 to move, the movement of the crawler frame 28 drives the second protective shell 26 to move, the movement of the second protective shell 26 drives the second permanent magnet 25 to move, the movement of the second permanent magnet 25 drives the crawler track 27 to move, so that the outside of the crawler track 27 abuts against the outside of the main steel column plate 6. At this time, the adsorption force of the climbing shell 10 on the main steel column plate 6 is reduced, and the climbing shell 10 can be pushed or pulled to move. When the worker climbs to the desired position, the rotating motor 14 is started in reverse, and the climbing shell 10 is firmly adsorbed on the outside of the main steel column plate 6, thereby improving the construction safety performance of the workers.

[0043] The detection device 4 is used to detect the adsorption ability of the climbing device 2 on the surface of the main steel column plate 6 in real time to avoid the danger of falling from a high altitude due to the decrease of magnetic force. The detection device 4 includes an avoidance groove 32 opened on one side of the inner wall of the climbing shell 10, and the inside of the avoidance groove 32 is fixedly connected with an air bag 33, and the top of the avoidance groove 32 is installed with a third permanent magnet 34. One side of the air bag 33 is connected with an air pipe 35, and the inside of the air pipe 35 is slidably connected with a sliding block 38. The top of the air pipe 35 is connected with a corrugated sleeve 39, and the top of the sliding block 38 is fixedly connected to the top of the inner wall of the corrugated sleeve 39. A mounting frame 36 is fixedly connected to one side of the inner wall of the climbing shell 10, and a pressure sensor 37 is fixedly connected to the top of the inner wall of the mounting frame 36, and the detection end of the pressure sensor 37 is abutted against the top of the corrugated sleeve 39.

[0044] Furthermore, in the above scheme, the first permanent magnet 11 moves away from the main steel column plate 6 while driving the climbing device 2 to gradually move away from the main steel column plate 6, and allows the outer parts of the two tracks 27 to abut against the outer parts of the main steel column plate 6, and the second permanent magnet 25 adsorbs the main steel column plate 6. When the climbing device 2 gradually moves away from the main steel column plate 6, the third permanent magnet 34 gradually moves away from the main steel column plate 6, the airbag 33 extends, the air pressure inside the airbag 33 decreases, and the sliding block 38 moves downward to drive the corrugated sleeve 39 to retract. At this time, the mounting frame 36 detects that the pressure is gradually decreasing. The reduction in the adsorption force between the third permanent magnet 34 and the main steel column plate 6 can positively reflect that the adsorption force of the first permanent magnet 11 on the main steel column plate 6 is proportionally reduced. In this way, the climbing device 2 can be adsorbed on the main steel column plate 6 to drive the outer part to ensure that it does not fall while facilitating the movement of workers.

[0045] Working principle of the present invention: when in use, firstly adsorb the climbing device 2 on the outer surface of the main steel column plate 6, then start the rotating motor 14, so that the two first permanent magnets 11 inside the climbing shell 10 gradually move away from the outer surface of the main steel column plate 6, and in the process of gradually moving the first permanent magnets 11 away from the outer surface of the main steel column plate 6, the two spring steel plates 22 are stressed and bent, and then the strain gauge 23 detects the curvature, and the maximum pulling force separating the climbing device 2 from the main steel column plate 6 can be known by detecting the curvature by the strain gauge 23, and the service life of the two first permanent magnets 11 and whether the main steel column plates 6 of different materials can still guarantee the safety of the workers can be known, and when the strain gauge 23 detects that the safety requirements for use are met, the required tools and bolts are placed inside the placement bag, and the climbing device 2 is tied to the worker with a rope, and the worker can climb to the top of the main steel column plate 6;

[0046] When the worker is climbing, he starts the rotating motor 14 again. The rotating motor 14 rotates to drive the first permanent magnet 11 away from the main steel column plate 6, while driving the climbing device 2 to gradually move away from the main steel column plate 6, and the outer parts of the two crawlers 27 abut against the outer part of the main steel column plate 6, and the second permanent magnet 25 adsorbs the main steel column plate 6. When the climbing device 2 gradually moves away from the main steel column plate 6, the third permanent magnet 34 gradually moves away from the main steel column plate 6, the air bag 33 stretches, the air pressure inside the air bag 33 decreases, and the sliding block 38 moves downward to drive the corrugated sleeve 39 to retract. At this time, the mounting frame 36 detects that the pressure is gradually decreasing. The reduction in the adsorption force between the third permanent magnet 34 and the main steel column plate 6 can positively reflect that the adsorption force of the first permanent magnet 11 on the main steel column plate 6 is proportionally reduced. In this way, the climbing device 2 can be adsorbed on the main steel column plate 6 to drive the outer part to ensure that it does not fall while facilitating the movement of the workers.

[0047] When the worker moves to the assembly site, the outer surface of the climbing device 2 is abutted against the outer surface of the main steel column plate 6 to maximize the adsorption force of the climbing device 2, and then the connecting steel plate 8 is lifted by the crane. At this time, the worker needs to adaptively adjust the connecting steel plate 8. After adjusting the connecting steel plate 8 to the approximate assembly position, the required parts and tools are adsorbed on the outside of the magnetic plate 45, and the slide cylinder 41 is pulled out, and then the slide cylinder 41 is fixed by screwing the fixing bolts 50, and then the position of the magnetic plate 45 is adjusted. After the adjustment is completed, the positioning device 5 is inserted into the connection between the assembly plate 7 and the connecting steel plate 8, and one of the expansion bars 49 is held to rotate the twist 51. The four expansion bars 49 are gradually expanded, and the assembly plate 7 and the connecting steel plate 8 are gradually weighed to ensure the accuracy of the position. In addition, multiple positioning devices 5 can be inserted for support to ensure the stability of the connection between the assembly plate 7 and the connecting steel plate 8, and then the extra holes are inserted into the bolts, and the magnetic plate 45 is used to resist to prevent the bolts from falling, and finally the nuts are screwed on. After completion, the positioning device 5 is removed and the bolts are screwed on.

9. A method for installing a high-rise assembled steel structure column, used for a high-rise assembled steel structure column installation device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: First, the climbing device (2) is adsorbed on the outer surface of the main steel column plate (6), and then the rotating motor (14) is started to gradually move the two first permanent magnets (11) inside the climbing shell (10) away from the outer surface of the main steel column plate (6). In the process of gradually moving the first permanent magnets (11) away from the outer surface of the main steel column plate (6), the two spring steel plates (22) are stressed and bent, and then the strain gauge (23) detects the curvature. By detecting the curvature through the strain gauge (23), the maximum pulling force separating the climbing device (2) and the main steel column plate (6) can be known, and the service life of the two first permanent magnets (11) and whether the main steel column plates (6) of different materials can still ensure the safety of the workers can be known. When the strain gauge (23) detects that the safety requirements for use are met, the required tools and bolts are placed inside the placement bag, and the climbing device (2) is tied to the worker with a rope. At this time, the worker can climb to the top of the main steel column plate (6); S2: When the worker is climbing, the rotating motor (14) is started again. The rotating motor (14) rotates to drive the first permanent magnet (11) away from the main steel column plate (6) and drives the climbing device (2) to gradually move away from the main steel column plate (6). The outer parts of the two crawlers (27) are in contact with the outer parts of the main steel column plate (6). The second permanent magnet (25) adsorbs the main steel column plate (6). When the climbing device (2) gradually moves away from the main steel column plate (6), the third permanent magnet (34) gradually moves away from the main steel column plate (6). , the airbag (33) stretches, the air pressure inside the airbag (33) decreases, the sliding block (38) moves downward to drive the corrugated sleeve (39) to retract, and at this time, the mounting frame (36) detects that the pressure is gradually decreasing. The decrease in the adsorption force between the third permanent magnet (34) and the main steel column plate (6) can positively reflect that the adsorption force of the first permanent magnet (11) on the main steel column plate (6) is proportionally reduced. In this way, the climbing device (2) can be adsorbed on the main steel column plate (6) to drive the outside to ensure that it does not fall, while facilitating the movement of workers; S3: When the worker moves to the assembly site, the outer surface of the climbing device (2) is brought into contact with the outer surface of the main steel column plate (6) to maximize the adsorption force of the climbing device (2), and then the connecting steel plate (8) is lifted by a crane. At this time, the worker needs to make adaptive adjustments to the connecting steel plate (8). After adjusting the connecting steel plate (8) to the approximate assembly position, the required parts and tools are adsorbed on the outside of the magnetic plate (45), and the slide cylinder (41) is pulled out, and the slide cylinder (41) is fixed by screwing the fixing bolts (50), and then the position of the magnetic plate (45) is adjusted. After the adjustment is completed, the positioning device (5) is inserted into the connection between the assembly plate (7) and the connecting steel plate (8), and the twist knob (51) is rotated to gradually weigh the assembly plate (7) and the connecting steel plate (8) to ensure the accuracy of the position. In addition, multiple positioning devices (5) can be inserted for support to ensure the stability of the connection between the assembly plate (7) and the connecting steel plate (8), and then the excess holes are inserted into the bolts, and the magnetic plate (45) is used to prevent the bolts from falling off, and finally the nuts are screwed on. After completion, the positioning device (5) is removed and the bolts are screwed on.
