[0002] With the continuous development of my country's construction industry, large-span steel structures are increasingly being used in many major projects due to their suitability for factory production, excellent seismic performance, minimal construction pollution, and short construction periods. Support cradles play an indispensable role in the installation of large-span steel trusses, serving as temporary supports for the steel structure trusses and providing a temporary work surface for the high-altitude assembly of the steel structure trusses.

[0003] Referring to prior art patent publication number CN220828086U, which discloses a steel structure support cradle that can adapt to steps, and prior art patent publication number CN220828061U, which discloses a support cradle for high-altitude assembly of steel structure trusses that enables efficient assembly, neither of these technologies considers the safety of workers during high-altitude assembly.

[0004] In 2022, the Ministry of Housing and Urban-Rural Development issued the "Standards for Determining Major Accident Hazards in Housing and Municipal Engineering Production Safety (2022 Edition)". It stipulates that during the construction of housing construction and municipal infrastructure projects (hereinafter referred to as housing and municipal engineering), production safety accident hazards with a high degree of harm that may cause mass deaths and injuries or cause major economic losses are called major accident hazards. Among them, the bearing capacity and deformation of the foundation of the supporting structure for steel structure and grid installation do not meet the design requirements; the supporting structure for steel structure and grid installation is not equipped with anti-overturning devices according to the design requirements, which will be judged as major accident hazards. Therefore, new requirements are put forward for the steel structure truss support cradle. Summary of the Invention

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0021] Example: Figure 1-Figure 2As shown, a safety-type steel structure truss support frame includes four support columns 1 distributed at the four corners. The support columns 1 are made of cylindrical steel pipes and connected by multiple steel lattice columns 2. An operating platform 3 is provided at the top end of the top lattice column 2. The operating platform 3 is made of steel pedals. The upper end of the support column 1 is provided with two symmetrically arranged mounting platforms 4. The mounting platforms 4 are made of I-beams and are used to place the steel structure trusses. The two mounting platforms 4 are connected by two connecting rods 5 made of steel pipes. The connecting rods 5 serve as guardrails for the operating platform 3 and can also be used to attach the safety belts of the workers.

[0022] Furthermore, when the site is limited, a rectangular steel plate of appropriate size can be installed at the bottom of the tire frame according to the height and width of the tire frame as the base plate 6. When the site is not limited, a square steel plate of appropriate size can be installed at the bottom of the tire frame according to the height and width of the tire frame as the base plate 6 to improve the bearing capacity of the foundation. A 45-degree inclined support 7 is welded between the bottom outer side of each support column 1 and the base plate 6 to prevent the tire frame from overturning.

[0023] When the cradle is at a low height, a straight ladder 8 is installed between the connecting rod 5 and the base plate 6. A fall arrester 9 is also installed on the connecting rod 5 to ensure that workers can safely reach the working platform at the top of the cradle. When the cradle is at a higher height, multiple inclined ladders 10 are installed between the connecting rod 5 and the base plate 6. A turnover platform 11 is installed between adjacent inclined ladders 10. The turnover platform 11 uses steel steps to make it safer and more convenient for workers to get on and off.

[0024] When workers are assembling steel structure trusses at high altitudes, they can hang their safety belts on the fall arrester 9, climb up the straight ladder 8 to reach the operating platform 3 at the top of the tire frame, and then hang the safety belts on the connecting rod 5 to carry out operations, thereby ensuring the safety of workers working at heights; an inclined support 7 is provided at the bottom of the tire frame to ensure the safety of the tire frame itself, while avoiding the occurrence of major accident hazards (the support structure for steel structure and grid installation is not equipped with an anti-overturning device as required by the design).

[0025] The above is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent scheme made using the contents of the present invention specification, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
