Description

Technical Field

[0001] This utility model relates to a support-free device, and more particularly to an adjustable support-free device for a large-span floor deck. Background Technology

[0002] Currently, steel structure high-rise building construction projects in China use floor decking for floor slab construction. In cases where the floor decking spans more than 3 meters, the central support of the floor decking is insufficient without backfilling, which can easily lead to deflection. On construction sites, steel pipe support frames are generally used to backfill the central part of the floor decking. Erecting steel pipe support frames requires a lot of labor and material costs, occupies construction space, and poses certain safety risks for high-altitude operations. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable, support-free device for large-span floor decking that is simple in design, easy to assemble, safe, efficient, and recyclable. It can effectively prevent the risk of downward deflection of large-span floor decking, control the flatness of the floor decking surface, and is reusable, saving costs, shortening installation and dismantling time, reducing safety risks, and solving the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model provides an adjustable, support-free device for large-span floor decking, comprising an upper fixing plate, a lower fixing plate, bolts, a steel wire rope, turnbuckles, and hooks. The upper and lower fixing plates are provided with inwardly folded hooks at their upper ends, which hook onto both sides of the bottom flange of the steel beam. The upper and lower fixing plates are connected by bolts. The fixing plates are provided with lifting rings, one end of the steel wire rope is fixed to the lifting ring, and the hook at the other end of the steel wire rope is connected to the upper reinforcing steel bar of the floor decking. Turnbuckles for tension adjustment are provided on the steel wire rope.

[0005] The upper fixing plate has two bolt holes in the middle, and the lower fixing plate has a rectangular opening in the middle. The bolts are screwed between the bolt holes and the rectangular opening.

[0006] The advantages of this utility model due to the adoption of the above technical solution are as follows:

[0007] ① The design is simple and the structure is optimized. The upper and lower fixing plates are used in conjunction with bolts, and the steel wire rope and turnbuckle are used for adjustment. The overall structure is simple and clear, reducing redundant parts and making it easy to manufacture and maintain.

[0008] ② Easy to assemble and efficient to construct. It adopts bolt connection and prefabricated fixing plate design, which does not require complicated tools or welding. The installation steps are simplified, significantly shortening the construction time and improving efficiency.

[0009] ③ The height is adjustable and highly adaptable. The double bolt holes of the upper fixing plate match the rectangular opening of the lower fixing plate. By adjusting the tightness of the bolts, it can be adapted to the width of the lower flange of different steel beams, flexibly meeting diverse engineering needs.

[0010] ④ The support-free design is safe and reliable. It uses steel wire ropes and turnbuckles to form a tensioning system, which directly connects the steel beams and the floor deck reinforcement. It eliminates the need for traditional temporary supports, reduces the risk of high-altitude operations, and avoids the hidden danger of support structure instability.

[0011] ⑤ Precise control of flatness: The turnbuckle's fine adjustment function can dynamically adjust the tension of the wire rope, effectively suppressing the deflection deformation of the floor deck and ensuring that the flatness of the deck meets the design requirements.

[0012] ⑥ It is recyclable, economical and environmentally friendly. All components (fixing plates, bolts, wire ropes, etc.) are standardized and detachable parts that can be reused in other projects, reducing material waste and lowering long-term costs.

[0013] ⑦ Shorten the construction period, reduce costs, eliminate the traditional support erection and dismantling process, significantly reduce labor and time costs, and save on the cost of renting or purchasing temporary supports.

[0014] ⑧ Modular application with strong scalability. The lifting lug design facilitates quick connection of steel wire ropes to form modular units, which can be flexibly arranged on floor decks of different spans or locations, expanding the applicable scenarios of the project.

[0015] ⑨ Safety risks are controllable. Through the synergistic effect of rigid fixing plates and flexible steel wire ropes, load stress is dispersed, local overload is avoided, the overall structure has high stability, and safety risks during construction and use are reduced.

[0016] In summary, this utility model, through its innovative adjustable support-free design, ensures the safety and flatness of large-span floor decking while also offering comprehensive advantages such as efficient construction, cost savings, and environmental friendliness, effectively overcoming the shortcomings of traditional technologies.

Figure 1 As shown, the structure includes an upper fixing plate 2, a lower fixing plate 3, a bolt 4, a steel wire rope 6, a turnbuckle 7, and a hook 5. The bottom flange of the steel beam 1 is equipped with an upper fixing plate 2 inserted into the lower left flange of the steel beam, and a lower fixing plate 3 inserted into the lower right flange. Hooks 21 and 31, folded upwards at both ends of the upper fixing plate 2 and the lower fixing plate 3, hook onto the flange of the steel beam 1 (see...). Figure 3 The upper fixing plate 2 and the lower fixing plate 3 are connected together by bolts. They are then pressed against the bottom flange plate of the steel beam 1. The steel beam 1 is connected to the floor deck 8 by hooks 5 at both ends of the wire rope 6, which are respectively hooked onto the lifting ring 31 of the lower fixing plate 3 and the upper reinforcing steel of the floor deck 8. The tightness is adjusted by turnbuckles 7 on the wire rope 6. (The text abruptly ends here.) Figure 2 As shown, the upper fixing plate 2 has two bolt holes in the middle, and the lower fixing plate 3 has a longitudinal rectangular opening in the middle. The bolts 4 are used to fix and tighten the plate, thus adapting to different widths of the lower flange of the steel beam.
