The main problems are the following: Challenges: 1. The traditional on-site pouring method, due to the large size of the beam section, belongs to mass concrete, and the quality and safety assurance measures of mass concrete are difficult to meet the requirements, resulting in many problems such as inconsistent quality and many safety hazards; 2. Traditional On-site pouring method, in order to meet the structural requirements and reinforcement ratio, the spacing between steel bars is too small, it is difficult to pour and vibrate on-site, and the quality is difficult to guarantee; 3. The site workload is large, the dust and noise pollution is serious, and it is greatly affected by the natural environment. It is long, and the construction progress is difficult to guarantee; 4. The traditional prefabricated components are self-heavy, and the site needs a support system. Due to the limitation of the site operating environment, the engineering installation accuracy is not high, and the structural safety at the nodes is poor, especially the cracks generated are difficult. Common problems; 5. The traditional prefabricated component system is heavy and has low seismic performance. The construction of the traditional cast-in-place steel reinforcement on site is time-consuming and labor-intensive, and the waste of resources is serious; 6. The support system has a large workload and many safety hazards. After the guarantee measures are in place, the follow-up process construction such as formwork installation can be carried out. The construction period is long and there are many safety hazards.
