Background technology
Precast reinforced concrete structure has had more practical application and more in developed countries such as America and Europe, Japan
Ripe technical research.Compared with traditional cast-in-place concrete, the craft at the precast reinforced concrete structure scene of can reducing
Work and wet construction, construction speed is fast, small to surrounding environment influence, and the quality of prefabricated components is easy to control, and the entirety of project is applied
Working medium amount is easier to ensure.
The research built with China to prefabricated assembled concrete is with wideling popularize, and prefabricated concrete structure is in China
Significant progress is obtained.
The connection of prefabricated components is one of key technique for influencing structure safety in prefabricated concrete structure.For height
Layer precast reinforced concrete structure, since the first floor is critically important to the anti-seismic performance of structure entirety, and the first floor is often due to building
The needs of function, it is less regular, therefore professional standard and each place code propose, in assembled integral concrete frame structure
First floor column preferably uses cast-in-place concrete.With the development of prefabricated concrete structure, further to reduce situ wet operation, accelerating
Construction speed, reduces the influence to surrounding environment, and for the relatively regular building of the first floor, its first floor column can be significantly using prefabricated components
Improve the construction efficiency of the first floor.
" strong ties " refer to structure under geological process, and when reaching maximum lateral displacement, structural elements enters mecystasis,
And connecting portion still keeps the connection of elastic stage.Under geological process, to avoid junction from destroying, it should be ensured that there is foot in junction
Enough intensity is allowed to be in elastic stage, and the section beyond connecting portion occurs for plastic deformation.For frame structure, plasticity becomes
First floor column bottom need to enter mecystasis and form plastic hinge in the development mechanism of shape, and after using strong ties, connecting portion is then located
In elastic stage, position of the plastic hinge more than connecting portion is formed.The type of attachment of assembled architecture is that column bottom fills at present
Sleeve is starched by the bar connecting of levels, to solve the technology of prefabricated concrete structure first floor column and basement roof strong ties
Problem, a kind of strong ties technology for prefabricated concrete structure column and basement roof with regard to it is particularly important that.
