Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road and bridge construction component installation, in particular to a spliced prefabricated component assembly and a construction method using the same. BACKGROUND

[0002] With the rapid development of infrastructure construction, bridge engineering requires more efficient, safer and more economical construction technology. Under the current trend, the technology of using prefabricated building components for construction has been widely used in super large bridge engineering and has achieved remarkable results.

[0003] In the current mode, prefabricated components including columns, beams and other components involved in the construction process can be modularly processed in the production plant and then transported to the construction site for splicing and assembly to complete the installation on site. This method avoids the inconvenience and quality control problems caused by traditional concrete pouring on site, and also improves the efficiency of the construction period.

[0004] In addition, during the production process, prefabricated components can be processed by automated equipment to ensure that each component has the same size and quality. In traditional construction, due to the uncertainty of manual operation, it is difficult to ensure that each component has the same size and quality. Prefabricated components can be transported by standardized transportation tools, avoiding the need for a large amount of on-site processing in the traditional construction process. At the same time, during on-site installation, prefabricated components can be completed by simple assembly, greatly shortening the construction period.

[0005] Bridges generally have long spans and complex structures, and traditional concrete pouring construction methods are often time-consuming and labor-intensive. The use of prefabricated building technology can process and modularly combine each component in advance, and only simple splicing is required on site to complete the installation. Since prefabricated components are strictly controlled and inspected during production, their quality is more easily guaranteed. Traditional pouring methods are easily affected by environmental factors and human factors, making it difficult to ensure construction quality. The use of prefabricated building technology can effectively avoid these problems and improve the overall quality of the bridge. Bridge engineering generally involves high-risk situations such as high-altitude work and complex environments. The use of traditional construction methods may result in personnel injuries, material waste and other problems. The prefabricated construction method will greatly reduce the number of high-altitude construction operations, thereby improving the safety of the construction process.

[0006] Therefore, reasonable modular design is required during the design stage. At the same time, the size of the prefabricated component and the on-site requirements need to be fully coordinated.

[0007] The problem in the prior art is that the lower structural members in the prefabricated components for bridge construction are mainly the bearing platform and the column, even if prefabricated, the actual construction method still cooperates with a large number of hoisting operations, especially the large-scale hoisting after the column cage is prefabricated, that is, the transportation and hoisting of large components are still generated in practice, which still restricts the construction and construction management.
