Description

Technical Field

[0001] This invention relates to the field of high-altitude construction operations, specifically a method for installing a suspended platform for a high-altitude beam without counterweight. Background Technology

[0002] The conventional installation method for suspended scaffolds used in building facade construction is to place counterweights on the roof. The counterweights themselves generate an anti-overturning moment to balance the overturning force caused by the outward cantilever of the scaffold during operation.

[0003] When there is a significant height difference between the structural beam and the roof at the work location, the counterweight can only be placed on the roof. The large difference between the lever arm of the lifting point and the counterweight poses a serious risk of overturning and falling. The concentrated load of the counterweight directly acts on the roof slab, which can easily cause cracking of the slab and leakage of the roof waterproofing layer. The transportation, hoisting, stacking, and dismantling of the counterweight are cumbersome, require a large amount of manpower, and result in low construction efficiency. The low walls of parapet walls have limited load-bearing capacity and cannot withstand the counterweight load, further compressing the usable conditions of the suspended platform.

[0004] Existing technologies include a few unweighted suspended platform solutions, most of which are designed for roof beams flush with the roof. These solutions are unsuitable for special building structures where the structural beams and roof are suspended high in the air, and cannot solve the practical problem of preventing the suspended platform suspension mechanism from overturning in high-suspension scenarios. Therefore, there is an urgent need to develop a suspended platform installation and construction method that is suitable for high-suspension beam conditions and does not require roof counterweights. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method for installing a suspended platform for a high-suspension beam without counterweight.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A method for installing a suspended platform for a high-suspension beam without counterweight includes the following construction steps:

[0008] S1. During the concrete pouring stage, the first anchor is installed on the frame beam to restrain the suspension mechanism of the suspended basket, and the second anchor is installed on the low wall of the building near the roof to connect the back tension member.

[0009] S2, The concrete structure of the structural beams and the low walls of the building reaches the design strength;

[0010] S3. Place the pad on the top surface of the frame beam. The suspended platform is located above the pad. The suspended platform is secured to the frame beam by means of the first anchor.

[0011] S4. Take the rear pull member, one end of which is connected to the rear end of the suspended platform suspension mechanism, and the other end of which is connected to the second anchor. Apply a pre-tightening operation to the rear pull member to counteract the outward overturning force of the suspended platform suspension mechanism.

[0012] S5. Lay working steel wire ropes on the suspension mechanism of the suspended platform;

[0013] S6. Hang the main body of the suspended platform on the working steel wire rope;

[0014] S7. Perform no-load test run, static load test run, and dynamic load test run in sequence. Check the connection positions of the first anchor and the second anchor, the back tension member, and the working status of the working wire rope. Construction work can be carried out after all inspection items meet the safe operation conditions.

[0015] Furthermore, the first anchor is either a pre-embedded bolt embedded in the frame beam or a clamp that wraps around and tightens the outside of the frame beam.

[0016] Furthermore, mounting holes are made in the pad plate that penetrate the plate surface, and the first anchor passes through the mounting holes of the pad plate to achieve positioning between the pad plate and the frame beam.

[0017] Furthermore, the second anchor is embedded inside the low wall during the concrete pouring of the low wall.

[0018] Furthermore, the back tension member can be a rigid tie rod or a flexible rope.

[0019] Furthermore, when applying pre-tightening to the rear tension member, the gap causing the basket suspension mechanism to shift outward is eliminated, allowing the rear tension member to continuously provide tension that restrains the overturning tendency of the basket suspension mechanism.

[0020] Furthermore, the items checked during the trial operation include whether the anchoring connection has slipped, whether the back tension member has undergone plastic deformation, and whether the wire rope has been damaged.

[0021] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0022] It is suitable for high-altitude suspended frame beam operation conditions. It relies on the pre-tightened back tension members to provide anti-overturning tension, completely eliminating the roof floor counterweight and eliminating the risk of overturning and falling of the suspension mechanism caused by unbalanced counterweight from the root.

[0023] The entire load of the suspended platform is transferred to the building frame beams, and the roof floor does not bear concentrated pressure, thus avoiding quality problems such as floor cracking and roof waterproofing leakage.

[0024] It completely eliminates the processes of purchasing, transporting, hoisting, stacking, and dismantling counterweight components, significantly improving on-site installation efficiency and reducing on-site labor input;

[0025] It is not constrained by the load-bearing capacity of roof slabs and can be applied to various high-suspended pergola beams and structural beams on the exterior facade of buildings.

[0026] Pre-embedded anchoring components have lower costs, and clamps can be reused, reducing project construction equipment costs. Attached Figure Description

[0032] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0033] like Figures 1 to 4 As shown in the figure, this embodiment provides a method for installing a suspended platform for a high-suspension beam without counterweight, including the following construction steps:

[0034] S1. During the concrete pouring stage, a first anchor 7 is installed on the frame beam 2 to restrain the suspended basket suspension mechanism 6, and a second anchor 9 is installed on the low wall 3 near the roof to connect the back tension member 10.

[0035] S2, the concrete structures of the structural beam 2 and the low building wall 3 have reached their design strength;

[0036] S3. Place the pad 8 on the top surface of the frame beam 2. The suspended platform suspension mechanism 6 is located above the pad 8. Weld and fix the column of the suspended platform suspension mechanism 6 above the pad 8. The subsequent construction is to disassemble and install as a whole. The suspended platform suspension mechanism 6 completes the fastening constraint between itself and the frame beam 2 with the help of the first anchor 7.

[0037] S4. Take the rear pull member 10. One end of the rear pull member 10 is connected to the rear end of the suspended platform suspension mechanism 6, and the other end of the rear pull member 10 is connected to the second anchor 9. Multiple sets of the rear pull member 10 and the second anchor 9 are matched and connected. At the same time, the rear end of the suspended platform suspension mechanism 6 is pulled together, and a pre-tightening operation is applied to the rear pull member 10 to counteract the outward overturning force of the suspended platform suspension mechanism 6.

[0038] S5. Lay working steel wire rope 5 on the suspended platform suspension mechanism 6;

[0039] S6. Hang the main body of the suspended platform 4 on the working steel wire rope 5;

[0040] S7. Perform no-load test run, static load test run, and dynamic load test run in sequence. Check the connection position of the first anchor 7, the connection position of the second anchor 9, the back tension member 10, and the working wire rope 5. Construction work can be carried out after all inspection items meet the safe operation conditions.

[0041] The first anchor 7 is either a pre-embedded bolt 72 embedded in the frame beam 2, or a clamp 71 that wraps around and clamps the outside of the frame beam 2.

[0042] The pad 8 has mounting holes that penetrate the surface of the plate, and the first anchor 7 passes through the mounting holes of the pad 8 to achieve positioning between the pad 8 and the frame beam 2.

[0043] The second anchor 9 is embedded inside the building wall 3 during the concrete pouring of the building wall 3.

[0044] The back tension member 10 can be a rigid tension rod or a flexible rope.

[0045] When the preload operation is applied to the pull member 10, the gap that causes the basket suspension mechanism 6 to shift outward is eliminated, so that the pull member 10 continuously provides tension to restrain the overturning tendency of the basket suspension mechanism 6.

[0046] After stress calculations confirm that the system meets the requirements for safe use, a trial run will be conducted. During the trial run, the items to be checked include whether the anchoring connection has slipped, whether the tension member 10 has undergone plastic deformation, and whether the working wire rope 5 has been damaged.

[0047] It is suitable for the working conditions of high-suspension frame beam 2. It relies on the pre-tightened back tension member 10 to provide anti-overturning tension, completely eliminating the counterweight of roof floor slab 1, and eliminating the risk of overturning and falling of the suspension mechanism caused by the imbalance of counterweight from the root.

[0048] The entire load of the suspended platform 4 is transferred to the building frame beam 2, and the roof floor slab 1 does not bear concentrated ballast, thus avoiding quality problems such as floor slab cracking and roof waterproofing layer leakage.

[0049] It completely eliminates the need for purchasing, transporting, hoisting, stacking, and dismantling counterweight components, significantly improving on-site installation efficiency and reducing on-site labor input.

[0050] Not constrained by the load-bearing conditions of roof slabs 1, it can be applied to various high-suspension pergola beams and structural beams 2 for building facade operations.

[0051] The cost of pre-embedded anchoring components is relatively low, and the clamp 71 can be reused, reducing the cost of construction equipment for the project.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
