Description
Technical field
The utility model relates to assembled arthitecutral structure node interconnection technique field, in particular to a kind of assembly concretes
Structural column and column rigid connection node.
Background technique
With the rapid development of our country's economy, living standards of the people are constantly promoted, and the requirement to house increasingly improves.Together
When, the cast-in-place construction mode and China's sustainable development idea of house are incompatible.Currently, China's house in the urgent need to address is built
If middle high energy consumption, high pollution, it is with high investment the problems such as, so house town and country construction portion of State Development and Reform Commission of China has promulgated that " green is built
Build action scheme ", the building such as the prefabricated assembled concrete structure for being suitble to industrialized production, steel construction is promoted wherein specifically mentioning
System accelerates development the prefabricated and mounting technology of construction project, and it is horizontal to improve building industrialization Integration ofTechnology.
Prefabricated assembled concrete structure has the advantage that
