Description

Technical Field

[0001] This utility model relates to the field of prefabricated concrete technology, specifically a prefabricated concrete connection structure. Background Technology

[0002] Prefabricated concrete buildings refer to concrete structures designed and constructed primarily using precast reinforced concrete components produced in factories, assembled on-site. They are generally divided into two main categories: fully prefabricated buildings and partially prefabricated buildings. Fully prefabricated buildings are typically low-rise or multi-story buildings with lower seismic fortification requirements; partially prefabricated buildings generally use precast components as their main components, which are connected on-site by cast-in-place concrete to form a prefabricated monolithic structure. The characteristics of this type of building are fast construction speed, suitability for winter construction, high production efficiency, good product quality, and reduced material waste.

[0003] Most existing prefabricated concrete connection structures are connected by pouring reinforced concrete. To ensure the stability of the structure, the connection process is relatively troublesome and complicated, requiring alignment and positioning, as well as subsequent fixing. This reduces work efficiency, increases the workload of workers, and raises construction costs. Utility Model Content
