Description

A support unit and system suitable for construction of prefabricated concrete frame structure Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and more particularly to a support unit and system suitable for the construction of prefabricated concrete frame structures. Background Art

[0002] As a form of construction that promotes the transformation of building construction towards industrialization, intelligence and greening, prefabricated buildings have developed rapidly in recent years with the national and local policies. However, the construction method of prefabricated buildings still uses traditional construction methods, resulting in a great waste of resources and cost increases.

[0003] Taking the prefabricated concrete formwork support unit as an example, the prefabricated components themselves have large bearing capacity and rigidity, but as support units, many projects still use full-floor scaffolding and full-coverage wooden formwork as the support units of prefabricated structures. As a result, the amount of measures for prefabricated structures has not been reduced compared to traditional structures, making it difficult to carry out interlaced construction.

[0004] In recent years, aluminum formwork support units have been used in many projects, which have played a significant role in construction quality and efficiency. In particular, thanks to the ideas of standardization and modularization, the turnover rate of aluminum formwork has been greatly improved. However, different projects require special formwork design and the turnover rate of aluminum formwork components needs to reach a higher number of times to achieve the cost competitive advantage with wooden formwork. At the same time, the high precision characteristics of aluminum formwork lack sufficient adjustment tolerance, which often leads to position conflicts with civil structure construction.

[0005] With the rapid development of prefabricated structures, independent supports have been expanded and applied as a new form of support. However, the support stability of independent supports is poor, so they have not been effectively popularized.
