Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a weightless suspended platform. Background Technology

[0002] Unweighted suspended platforms are widely used in high-altitude operations such as construction, exterior wall cleaning, and high-altitude maintenance. Unlike traditional counterweighted suspended platforms, unweighted suspended platforms eliminate the need for a bottom counterweight. Their stability and safety are ensured through a unique structure and technology. Structurally, they typically employ advanced anchoring and suspension systems, directly and securely connecting to the main building structure, safely suspending the work platform in the air. This type of platform offers numerous advantages. First, it saves the space occupied by counterweights, making it very suitable for work environments with limited space. Second, the absence of counterweights significantly reduces workload during installation and dismantling, improving construction efficiency. Furthermore, it is more convenient to transport, reducing transportation costs.

[0003] However, the traditional method for exterior facade construction in some existing projects involves adding a suspended platform with counterweights to the roof and erecting a roof counterweight frame. This results in a large number of roof counterweights and a dense network of safety ropes and cables, posing numerous risks such as broken safety ropes and shifted counterweights. Furthermore, the handling of counterweights during construction is complex, significantly increasing the labor required and making subsequent roof construction more difficult. This also impacts the construction schedule (the suspended platform must be dismantled after the exterior facade construction is completed), negatively affecting the project's timeline, quality, and safety. Therefore, to address these shortcomings, a counterweight-free suspended platform is proposed to solve the aforementioned problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a weightless suspended platform, which aims to improve the problem that some construction methods in the prior art, which use additional weights on the suspended platform, are difficult to use and not safe or effective enough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A counterweight-free suspended platform includes a concrete beam. A connecting assembly for fixing is provided on the right side of the interior of the concrete beam. Two curtain wall steel frames are fixedly connected to the right side of the connecting assembly. Two connecting steel frames are fixedly connected to adjacent sides of the two curtain wall steel frames. Two curtain wall column piers are fixedly connected to the bottom of one of the curtain wall steel frames. Two suspended platform steel frames are fixedly connected to the exterior of the two curtain wall steel frames. Connecting ropes are fixedly connected to the bottom of each of the two suspended platform steel frames. A suspended platform is fixedly connected to the bottom of each of the two connecting ropes. An inclined steel frame is fixedly connected to the bottom of each of the two suspended platform steel frames.

[0007] As a further description of the above technical solution:

[0008] The connecting assembly includes two embedded pads, both of which are externally fixedly connected to the inside right side of the concrete beam, and both of which are internally threaded with multiple through bolts.

[0009] As a further description of the above technical solution:

[0010] The external thread of the through bolt is connected to the inside of the concrete beam, and the bottom of the inclined steel frame is fixedly connected to the top of another curtain wall steel frame;

[0011] As a further description of the above technical solution:

[0012] The curtain wall steel frame, the suspended basket steel frame, and the inclined steel frame are welded using steel pipes, and the surface weld slag is removed and rust inhibitor is applied.

[0013] This utility model has the following beneficial effects:

[0014] In this utility model, the installation and use of the suspended platform are achieved through the permanent and temporary combination of the suspended platform steel frame and the curtain wall steel frame. This effectively saves labor costs caused by excessive counterweight, saves roof space, and reduces the impact of roof space on subsequent construction. It also increases the safety of facade construction, reduces safety hazards caused by the back-and-forth movement of counterweight, and the tools are simple to make and have significant effects.

[0020] 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.

[0021] Reference Figures 1 to 3 This utility model provides an embodiment of a counterweight-free suspended platform, comprising a concrete beam 1. In construction engineering, the concrete beam 1 serves as the foundation support structure for the entire counterweight-free suspended platform device. A fixing connection assembly is provided on the right side of the interior of the concrete beam 1. The connection assembly includes two embedded pads 2. During construction, the exterior of the embedded pads 2 is tightly fixed to the concrete beam 1, ensuring that there will be no loosening or displacement during long-term use. The exterior of both embedded pads 2 is fixedly connected to the right side of the interior of the concrete beam 1. Multiple through bolts 3 are threadedly connected to the interior of each embedded pad 2. The external threads of the through bolts 3 are connected to the interior of the concrete beam 1. During installation, the external threads of the through bolts 3 engage with the internal threads of the concrete beam 1 and the embedded pads 2, forming a robust connection. Two curtain wall steel frames 4 are fixedly connected to the right side of the connection assembly. Two connecting steel frames 5 are fixedly connected to the adjacent sides of the two curtain wall steel frames 4. The curtain wall steel frames 4 are connected through the connecting steel frames 5, further enhancing the overall stability and rigidity.

[0022] Reference Figures 1 to 3 One of the curtain wall steel frames 4 has two curtain wall column piers 6 fixedly connected to its bottom. Two suspended platform steel frames 7 are fixedly connected to the exterior of the two curtain wall steel frames 4. The suspended platform steel frames 7 are welded from steel pipes and have sufficient strength and rigidity to bear the weight of the suspended platform 9, construction personnel, and materials. During construction, the connection between the suspended platform steel frames 7 and the curtain wall steel frames 4 is achieved by welding. This combination of permanent and temporary connections not only ensures the strength of the connection but also improves construction efficiency and the overall stability of the system. Connecting ropes 8 are fixedly connected to the bottom of each of the two suspended platform steel frames 7, and suspended platforms 9 are fixedly connected to the bottom of each of the two connecting ropes 8. The suspended platforms 9 are the working platforms used to support construction personnel and materials in the unbalanced suspended platform device. Suspended below the suspended platform steel frames 7 by the connecting ropes 8, they serve as the main work area for construction personnel to carry out facade construction. Both of the suspended platform steel frames 7 are fixedly connected to the bottom of inclined steel frames 10. The bottom of the inclined steel frames 10 is fixedly connected to the top of another curtain wall steel frame 4. The bottom of the inclined steel frames 10 is welded to the top of the other curtain wall steel frame 4, and the top is welded to the bottom of the suspended platform steel frame 7 to form a fixed, triangular, stable structure. The curtain wall steel frame 4, the suspended platform steel frame 7, and the inclined steel frames 10 are welded using steel pipes, and the surface weld slag is removed and rust inhibitor is applied.

[0023] Working Principle: First, in building construction, for exterior facade projects, particularly in roof structure projects such as roof design and roof pergola construction, pre-installation and embedding work is carried out. On roofs with design space, concrete bolts for the exterior facade are pre-embedded in the concrete beams 1 or walls before concrete pouring. During roof structure construction, components such as columns and piers are pre-installed according to design requirements. The curtain wall steel frame 4 is pre-installed and embedded according to the column and pier requirements, the bolt locations are positioned and fixed, and the concrete is poured in one go. After the concrete strength requirements are met, the horizontal steel frame of the roof curtain wall is constructed, making the curtain wall steel frame 4 a unified whole. Then, the suspended platform 9 is installed on the roof structure. The curtain wall steel frame 4 is connected to the concrete beam 1 via connecting components. The pre-embedded pad 2 in the connecting components is embedded inside the right side of the concrete beam 1, and through bolts 3 are used to fix it to the concrete beam 1. The curtain wall steel frame 4 is welded to the connecting steel frame 5 for fixation, and the suspended platform steel frame 7 is welded to the curtain wall steel frame 4 for fixation. The suspended platform 9 is connected to the suspended platform steel frame 7 via connecting ropes 8. An inclined steel frame 10 connects the two curtain wall steel frames 4 and its bottom is connected to the suspended platform steel frame 7, forming a stable structure. In this design, the suspended platform steel frame 7 and the curtain wall steel frame 4 are combined in a permanent and temporary manner. After welding, the welding quality and the spacing of the counterweight supports are checked. After acceptance, it is put into use. After the exterior facade construction is completed, the curtain wall steel frame 4 is not removed as required; only the counterweight supports are removed. This design greatly saves roof space and facilitates subsequent roof waterproofing and other construction processes.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
