Description

Technical Field

[0001] This invention relates to the field of steel structure engineering suspended platform construction technology, specifically to a beam-type suspended platform anti-counterweight bracket fixing and suspension device. Background Technology

[0002] Construction suspended platforms have gradually become a trend, capable of replacing traditional scaffolding, reducing labor intensity, and improving work efficiency. Traditional cantilever suspended platform suspension mechanisms are set on the floor and roof eaves areas, with bolted front supports and counterweights on the rear supports. Currently, these mechanisms can no longer fully meet the requirements for suspended platform suspension during exterior facade construction.

[0003] Patent CN218597699U discloses a counterweight-free suspended platform structure, comprising a front beam, a middle beam, and a rear beam. All three beams are horizontally arranged, with the outer ends of the middle beam slidingly engaging with the inner walls of the front and rear beams, respectively. The front and rear beams are connected to the middle beam at their sliding engagement points using through-bolts. The advantages are: the sliding engagement allows for rapid connection of the front, rear, and middle beams, and the through-bolts via mating holes allow for adjustment of the overall length after connection, facilitating rapid assembly and on-site deployment of the suspension structure.

[0004] Such counterweight-free suspended platform devices are particularly problematic in complex-shaped public buildings, high-rise buildings with protruding rooftop "flower racks," and tall factories. These projects involve high construction heights, and the steel frame structure alone cannot accommodate counterweights or suspension mechanisms, making it difficult to install the suspended platform. The support structure is also not ideal. Furthermore, typical suspension devices use a single cantilever beam structure, and the fixed support mechanism is relatively simple, resulting in low strength and poor stability, making them prone to swaying or tipping, posing certain construction safety hazards. Using scaffolding to erect the support frame wastes materials, is difficult to recycle, and has high construction costs, contradicting the principles of energy conservation and material saving. Summary of the Invention

[0005] The purpose of this invention is to provide a beam-type suspended platform without counterweight support fixing and suspension device, which overcomes the problems of poor fixing effect of existing beam-type suspended platform without counterweight support when applied to various complex steel frame structures, and the use of a single cantilever beam structure, resulting in low strength and stability, and easy swinging or tipping during use.

[0006] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: A cantilever beam-type suspended platform suspension device without counterweight support was designed. The cantilever beam is firmly fixed to the steel structure via front and rear support fixing devices. A double cantilever beam structure is used to suspend the platform. A traction protection device is installed on the double cantilever beam structure, which enhances the suspension strength and improves its stability during use, preventing easy swaying and improving the safety of construction projects. The specific scheme is as follows: A cantilever beam type suspended platform without counterweight support fixing and suspension device includes two cantilever beams arranged in parallel.

The second angle steel clamp is located on the upper side of the serrated adapter. The second angle steel clamp and the H-beam are connected in series by four equidistant second U-shaped clamps, and the serrated adapter is fastened by nuts and washers.

[0012] Preferably, the tension protection device includes two tension members and an abutment member. The two tension members are abutted against each other and respectively connected to the two cantilever beams. The abutment member abuts against the tension member and the H-shaped steel beam on the outside of the cantilever beam.

[0013] Preferably, the tensioning member consists of a butt joint section and a connecting section. The butt joint sections overlap each other and are connected by bolts.

[0025] like Figure 1 As shown in Figures 2, 4, 5, 6, and 7, this invention provides a cantilever beam type suspended platform without counterweight support fixing and suspension device, including a cantilever beam 1. Two cantilever beams 1 are arranged in parallel. The front and rear ends of the cantilever beam 1 are respectively connected to the H-shaped steel beam of the steel structure project below the cantilever beam 1 through the front support fixing device 3 and the rear support counterweight-free fixing device 2. The cantilever beam 1 and the H-shaped steel beam are kept in a horizontal state, which can firmly fix the cantilever beam 1 to the steel frame structure of various complex building projects.

[0026] In the above scheme, the upper end of the front support fixing device 3 is connected to the column 5, the top of the column 5 is connected to the rear end of the cantilever beam 1 through the rear tie rod 51, the top of the column 5 is connected to the front end of the cantilever beam 1 through the front tie rod 52, and the front end of the cantilever beam 1 extends out of the exterior of the steel structure project and is suspended by the suspension platform 6.

[0027] As an optimized technical solution of the present invention, the top of the column 5 is higher than the cantilever beam 1 by a certain distance, so that the front tie rod 52, the rear tie rod 51 and the cantilever beam 1 form a triangle, and the suspension platform 6 is suspended at the front end of the cantilever beam 1 by the wire rope 61. At the same time, the wire rope 61 is equipped with a limit block 62 to prevent the suspension platform 6 from colliding with the cantilever beam 1 during the process of being pulled by the wire rope 61.

[0028] In the above scheme, the cantilever beam 1 is composed of a front beam 11, a middle beam 12 and a rear beam 13 connected sequentially from front to back by bolts.

[0029] As an optimized technical solution of the present invention, the segmented bolt connection of the cantilever beam 1 allows the length of the cantilever beam 1 to be adjusted according to the actual use, so as to ensure sufficient installation space.

The front fixing component is connected to the H-shaped steel beam, the front support component is connected to the front fixing component, and the front support component is connected to the front end of the cantilever beam 1.

[0031] As an optimized technical solution of the present invention, the front fixing component connects the cantilever beam 1 to the steel frame structure through the front support component, thereby completing the installation of the front end of the cantilever beam 1. This ensures that the cantilever beam 1 has a sufficient safe distance to install the suspension platform 6 when it extends out of the exterior of the steel structure project, and plays a crucial supporting role for the front end of the cantilever beam 1.

[0032] In the above scheme, the front fixing component includes a first U-shaped clamp 33, a U-shaped adapter 34 and a first angle steel clamp 35. The U-shaped adapter 34 is a U-shaped structure welded from three square tubes. The bottom of the front support component is fixed by the U-shaped adapter 34. The first angle steel clamp 35 is located on the upper side of the U-shaped adapter 34. The first angle steel clamp 35 and the H-shaped steel beam are connected in series by two equidistant first U-shaped clamps 33, and the U-shaped adapter 34 is fastened by nuts and washers.

[0033] As an optimized technical solution of the present invention, the front support assembly includes a front bracket 31 and a first insert rod 32. The upper end of the first insert rod 32 is bolted to the front beam 11 of the cantilever beam 1, and the lower end of the first insert rod 32 is bolted to the upper end of the front bracket 31. Diagonal braces 311 are welded to the front and rear sides of the lower end of the front bracket 31. The lower ends of the diagonal braces 311 are welded together with the first bottom crossbeam 312. The first bottom crossbeam 312 can then be fixed by the U-shaped adapter 34, improving the fixing effect of the front support assembly. The first U-shaped clamp 33 and the first angle steel clamp 35 are then fastened to the H-shaped steel beam of the steel structure by means of washers and nuts, thereby ensuring the overall stability of the front bracket structure and greatly improving its fixing effect.

[0034] In the above scheme, the rear support counterweight-free fixing device 2 includes a rear fixing component and a rear support component. The rear fixing component is connected to the H-shaped steel beam, the rear support component is connected to the rear fixing component, and the rear support component is connected to the rear end of the cantilever beam 1.

[0035] As an optimized technical solution of the present invention, the rear fixing component connects the rear end of the cantilever beam 1 to the steel frame structure through the rear support component, so as to improve the stress effect of the rear end of the cantilever beam 1, bear part of the tensile force generated by the suspension platform 6 at the front end of the cantilever beam 1, and play the same role as the counterweight.

[0036] In the above scheme, the rear fixing device includes a sawtooth adapter 23, a second U-shaped clamp 24, and a second angle steel clamp 25. The sawtooth adapter 23 is a sawtooth structure welded from five square tubes. The bottom of the rear support assembly is fixed by the sawtooth adapter 23. The second angle steel clamp 25 is located on the upper side of the sawtooth adapter 23. The second angle steel clamp 25 and the H-shaped steel beam are connected in series by four equidistant second U-shaped clamps 24, and the sawtooth adapter 23 is fastened by nuts and washers.

[0037] As an optimized technical solution of the present invention, the rear support assembly includes a rear bracket 21 and a second insert rod 22. The upper end of the second insert rod 22 is bolted to the rear end of the rear beam 13 of the cantilever beam 1, and the lower end of the second insert rod 22 is bolted to the upper end of the rear bracket 21. A second bottom crossbeam 211 is welded to the lower end of the rear bracket 21. The second bottom crossbeam 211 is fixed by a sawtooth adapter 23, and then secured to the H-shaped steel beam of the steel structure by a second U-shaped clamp 24 and a second angle steel clamp 25 with nuts, thereby ensuring the structural stability of the rear bracket and eliminating the need for counterweights. Specific Implementation

[0038] When constructing suspended platforms on various complex-shaped public buildings, high-rise buildings with prominent rooftop "flower racks," and tall factory buildings, where the construction height is high and only a steel frame structure is used, the following steps are taken: First, install the front support fixing device 3 and the rear support counterweight-free fixing device 2 on two adjacent H-shaped steel beams respectively. Ensure that the front support fixing device 3 and the rear support counterweight-free fixing device 2 are on the same horizontal line. Then, connect the cantilever beam 1 between the front support fixing device 3 and the rear support counterweight-free fixing device 2 on the same side using bolts. The length of the cantilever beam 1 can be determined by changing the bolt connection positions of the front beam 11, the middle beam 12, and the rear beam 13 according to the actual installation position.

[0039] Next, the column 5 is bolted to the top of the front support fixing device 3, and the front tie rod 52 and the rear tie rod 51 are bolted to the top of the column 5 and the front and rear sides of the cantilever beam 1. At the same time, the suspension platform 6 is connected to the front end of the two cantilever beams 1 by steel wire rope 61, so that the steel wire rope 61 is connected to both sides of the suspension platform 6 to maintain the stability of the suspension platform 6. In this way, the suspension platform 6 will not easily swing significantly during the construction process, thus ensuring the safety of the construction personnel. Example

[0040] like Figure 3 As shown in Figures 8, 9, and 10, based on Example 1, the difference from Example 1 is that two tension protection devices 4 are provided between the two cantilever beams 1 to improve the stability of the entire device. The tension protection devices 4 abut against the H-shaped steel beam of the steel structure outside the cantilever beam 1, which can further improve the stability of the cantilever beam 1 during use, enhance its strength, and prevent it from shaking or being too weak during use.

[0041] In the above scheme, the tension protection device 4 includes two tension members 41 and an abutment member 42. The two tension members 41 are connected to each other and respectively connected to two cantilever beams 1. The abutment member 42 abuts between the tension member 41 and the H-shaped steel beam on the outside of the cantilever beam 1.

[0042] As an optimized technical solution of the present invention, an installation block 43 is provided on the outside of the tension member 41 to facilitate the stable contact of the abutment member 42. The two cantilever beams 1 are connected together by the abutment member 42 and the tension member 41, and the two support and restrain each other, which greatly improves the stability and strength of the entire device.

[0043] In the above scheme, the tensioning member 41 is composed of a docking section 411 and a connecting section 412. The docking sections 411 overlap each other and are connected by bolts. The connecting section 412 is a downwardly bent hook-shaped structure. A fastening member 44 is slidably connected to the docking section 411. The fastening member 44 is used to cooperate with the connecting section 412 to clamp the cantilever beam 1.

[0044] As an optimized technical solution of the present invention, the fastening member 44 includes a sliding sleeve 441, an L-shaped fastening plate 442, and a fastening bolt 443. The sliding sleeve 441 is slidably connected to the mating section 411, the L-shaped fastening plate 442 is connected to the lower side of the sliding sleeve 441, and the fastening bolt 443 is threadedly connected to the lowermost end of the L-shaped fastening plate 442 and threadedly connected to the lowermost end of the connecting section 412. When one side of the cantilever beam 1 abuts into the connecting section 412, the sliding sleeve 441 causes the fastening plate 442 to press against the other side of the cantilever beam 1, and the fastening bolt 443 fastens the lower end of the connecting section 412 and the fastening plate 442 together. With the help of the tensioning member 41, the cantilever beam 1 achieves a mutual restraint and abutment effect.

[0045] In the above scheme, the abutting member 42 includes an adjusting sleeve 421, an abutting screw 422, and a V-shaped angle plate 423. The abutting screw 422 consists of two screws with opposite directions of rotation, which are threaded to both ends of the adjusting sleeve 421. There are two V-shaped angle plates 423, which are movably connected to the free end of the abutting screw 422. The V-shaped angle plates 423 abut against the pulling member 41 and the H-shaped steel beam, respectively.

[0046] As an optimized technical solution of the present invention, by rotating the adjusting sleeve 421, the abutting screw 422 extends outward, and the two V-shaped angle plates 423 are respectively clamped on the mounting block 43 and the H-shaped steel beam of the steel frame structure through their unique V-shaped groove structure, abutting against the cantilever beam 1 from the outside to prevent it from tipping over. Specific Implementation

[0047] After the suspended platform is installed on the steel frame structure, the tension protection device 4 can be installed between the front beams 11 and the rear beams 13 on both sides. During the installation of the tension protection device, tension members 41 are first installed on the two cantilever beams 1 respectively, so that they fit tightly against the outer side of the cantilever beam 1. The overlapping position of the two tension members 41 is fixed with bolts. Then, the sliding sleeve 441 is slid so that the fastening plate 442 is close to the inner side of the cantilever beam 1. The connecting section 412 and the lower end of the fastening plate 442 are fastened together with the fastening bolts 443. Then, the tension members 41 work together to achieve a mutual restraint and abutment effect on the cantilever beam 1.

[0048] At that time, the V-groove structure of the V-shaped angle plate 423 at one end of the abutment 42 is inserted into the mounting block 43. By rotating the adjusting sleeve 421, the abutment screw 422 extends outward until the V-groove structure of the other end of the V-shaped angle plate 423 is inserted into the H-shaped steel beam of the steel frame structure, so that the abutment 42 abuts between the cantilever beam 1 and the H-shaped steel beam, which plays a good protective role and effectively prevents the suspended platform from tipping over during use.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
