Technical Field

[0001] This invention relates to the field of precast formwork technology, and in particular to a connection structure for precast formwork in civil engineering. Background Technology

[0002] Civil engineering is the science and technology of constructing various engineering facilities, with a wide range of applications including architecture, transportation, water conservancy, and disaster prevention. Formwork engineering is a crucial part of civil engineering construction, affecting both the quality of concrete structures and construction efficiency. Especially in the field of precast formwork, achieving rapid, efficient, and precise connection of formwork has always been a key research focus. While traditional cast-in-place reinforced concrete technology, also known as wet construction, has contributed significantly to the rapid development of urban and rural construction, its drawbacks are becoming increasingly prominent, such as serious waste of steel and cement, excessive water consumption, and poor construction site environment. Therefore, transforming traditional construction methods and developing prefabricated buildings is also a necessity for energy conservation and environmental protection.
