It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0025] The steel plate composite beam assembly operating platform provided in the embodiment of the present application is as follows: Figure 1 and 2 As shown, it includes: two parallel main beams 1, which provide the main force and connection structure for the entire operating platform structure to ensure the stability of the operating platform during use, and two support structures 2 arranged between the two main beams 1, which ensure the stability of the two main beams during construction to prevent the operating platform from tilting on one side and falling off the bottom plate of the steel main beam. The plate structure 3 arranged on the main beam 1 provides a platform for workers to install the steel plate composite beam flat joint, cast-in-place bridge panel bracket and template installation and disassembly, so as to facilitate the workers' installation operations.

[0026] In order to facilitate the movement of the operating platform, rollers 4 are provided at both ends of the main beam 1 for traveling along the first direction of the bridge. The first direction is along the bridge. In the embodiment provided in the present application, the rollers 4 of the same main beam 1 travel on adjacent walking platforms. Optionally, the walking platform is a steel main beam bottom plate 5, that is, the rollers 4 travel on the steel main beam bottom plate 5. In the embodiment provided in the present application, since the steel main beam bottom plate 5 at the bottom of the longitudinal beam 10 of the steel main beam of the steel plate composite beam has more abundant travel space on both sides, the rollers 4 use longitudinal universal wheels, so that the entire operating platform structure can travel along the bridge when the longitudinal universal wheels travel. A limiter 6 is provided at the end of the main beam 1, which is directly opposite to the side of the walking platform (steel main beam bottom plate 5). The limiter 6 prevents one end of the main beam 1 from sliding off the steel main beam bottom plate 5 during the operation of the operating platform.

[0027] The steel plate composite beam assembly operating platform of this embodiment provided in the present application is as follows: Figure 1 and 2 As shown, when the main beam 1 is set lower than the walking platform, the main beam 1 is set below the steel main beam bottom plate 5, and two roller connectors 7 connected to the rollers 4 are set at both ends of the main beam 1. The rollers 4 connected by the two roller connectors 7 are set on two opposite and adjacent walking platforms, that is, they are set on the top surface of the steel main beam bottom plate 5 on both sides of the same longitudinal beam along the bridge. The roller connectors 7 are set above the two ends of the main beam 1, and extend from the end away from the main beam to the longitudinal beam 10 in the steel main beam. The rollers 4 are set at the ends of the extension sections of the roller connectors 7 to the steel main beam longitudinal beam 10 to ensure that the rollers 4 can travel on the top surface of the steel main beam bottom plate 5. The roller connectors 7 can be connected by steel sections or cast in an integrated manner.

[0028] In order to ensure the transverse movement of the operating platform during the construction process and prevent the operating platform from falling, the limiter 6 is arranged at one end of the roller connector 7 connected to the roller 4, and is directly opposite to the side of the steel main beam bottom plate 5, and the transverse direction is a direction perpendicular to the first direction. Optionally, the limiter 6 is a roller whose rolling axis is perpendicular to the walking platform, so that the roller can roll along the side of the steel main beam bottom plate 5, and the limiter 6 is arranged in the roller connector 7. Since a longitudinal beam 10 is arranged above the middle of the steel main beam bottom plate in the transverse direction, the steel main beam bottom plate 5 can be stuck in the roller connector 7, and the limiter 6 restricts the roller from sliding off one side of the steel main beam bottom plate 5, so that the operating platform will not slide off from both sides of the steel main beam bottom plate 5 during use, thereby ensuring construction safety.

[0029] In the present embodiment provided by the present application, Figure 1 and 2As shown, the main beam 1 includes a first end 12 and a second end 13, and the first end 12 is provided with a roller 4. The roller 4 provided at the first end 12 of the corresponding main beam 1 is located below the bottom surface of the steel main beam bottom plate 5. During the sliding process of the operating platform, when the first end 12 of the main beam 1 is tilted upward, it will not be in rigid contact with the steel main beam bottom plate 5, that is, it will not scratch or deform the end of the main beam 1 and the bottom surface of the steel main beam bottom plate 5, thereby reducing the friction between the first end 12 of the main beam 1 and the steel main beam bottom plate 5. Optionally, the second end 13 of the main beam extends a roller connector 7 away from the first end 12, and the roller connector 7 is bolted to the main beam 1, so that the operating platform is easy to install and disassemble, and can be reused. The extension section 14 of the two main beams 1 is provided with a plate structure 3, and the extension section 14 and the plate structure 3 provide an operating platform for workers to operate, and the plate structure 3 is made of a metal mesh plate. Optionally, a guardrail structure 8 connected to the extension section 14 is provided above the end of the extension section 14. Optionally, the two guardrail structures 8 at the ends of the two extension sections 14 are connected through the steel pipe 9. The guardrail structure 8 ensures the safety of workers during construction operations, and the steel pipe 9 connecting the two guardrail structures 8 ensures the stability of the guardrail structure, further ensuring the construction safety of workers.

[0030] The steel plate composite beam assembly operating platform provided in the embodiment of the present application can also be equipped with a guardrail structure along the main beam axis to ensure the safety of workers working along the bridge. In the embodiment provided in the present application, the main beam and the supporting structure are supported by steel sections, and the plate structure is composed of metal grid plates or steel gratings. The materials can be obtained from the construction site, thereby reducing the operating cost, and the dimensions of each structure can be adjusted according to the main beam spacing and the spacing between the cross beam and the main beam bottom plate, so that the operating platform provided in the present application is economical and easy to operate, and can also be operated by multiple people.

[0031] The steel plate composite beam assembled operating platform in the present embodiment provided by the present application, the rollers connected to the roller connectors at both ends of the main beam can also be arranged on the top surfaces of two opposite and adjacent walking platforms, that is, on the bottom plates of two opposite and adjacent steel main beams, and a plate structure is placed on the main beam, so that the end of the main beam is clamped on the bottom plate of the steel main beam through the roller connector, thereby facilitating the construction of the plate structure placed on the main beam.

[0032] In summary, the steel plate composite beam assembled operating platform provided by the present application has the following beneficial effects:

[0033] The steel plate composite beam assembly operating platform provided in the embodiment of the present application includes: mutually parallel main beams, an operating platform structure arranged between the main beams, rollers that travel along the first direction are arranged at both ends of the main beams, the rollers of the same main beam are respectively clamped on adjacent walking platforms, and the ends of the main beams are provided with limiters that face the sides of the walking platform. The present application forms a frame-type operating platform beam body through the main beam and the supporting structure, and builds a plate structure above the beam body to provide workers with a platform for parallel installation of steel plate composite beams, installation and disassembly of cast-in-place bridge deck brackets and formwork, so as to realize the workers' installation operations. The longitudinal beam bottom plate of the steel main beam of the steel plate composite beam has relatively abundant driving space on both sides, and the rollers adopt longitudinal universal wheels, so that the entire operating platform can move along the bridge direction when the longitudinal universal wheels are running, and the limiters prevent one end of the main beam from sliding off the steel main beam bottom plate during the driving of the operating platform.
