According to the definition of the national standard "Technical Standard for Assembled Concrete Building", the assembled concrete building refers to the assembled building whose structural system is composed of concrete members (prefabricated members).
Dry connection is widely used in the development of prefabricated concrete buildings. Early assembled concrete was mainly low-rise and multi-storey. In areas with low seismic performance requirements, dry connection has great advantages over cast-in-place concrete buildings because of its fast construction speed and low cost.

Precautions:
Precast components (beams and slabs) shall be installed with an installation plan and a unified command system. Training should be organized for difficult and dangerous operation projects.
When the roller works near the edge of the embankment, it should keep a necessary safe distance according to the height of the embankment. This road must go from the inside out.
