Description
Technical field
The invention belongs to prefabricated reinforced concrete structure technical field, specifically a kind of reinforced concrete precast member.
Background technique
Field fabrication is more in monolithic reinforced concrete structure work progress, and wet construction is more, there is a large amount of form work engineerings, scaffold
The intermediate links such as engineering, waste of resource pollute environment；Practitioner's quality, construction environment etc. influence very big, band to build guality
The problems such as coming building performance, quality and durability.It changes the status quo, precast concrete should be greatly developed, reduce scene system
Make concrete structure amount, improves prefabricated rate.The primary structural member of precast concrete makes in factory, production efficiency
It is high, high-quality, resource and the energy are saved, sustainable development is conducive to.It is building industrialization development using precast concrete
Direction.
