Description
Technical field
The present invention relates to a kind of half prefabricated profile steel concrete column-girder with rolled steel section en cased in concrete node units, belong to Building technology neck
Domain and technical field of structural engineering.
Background technique
During modernized society's development, reinforced concrete construction technology has the development of leap, cast-in-place concrete
Construction technology also has gradually developed.Since cast-in-place concrete is with good performance and superiority, various
It is widely used in civil engineering.But there is also some problems, such as curing concrete for cast-in-place concrete
Need that a large amount of template, workload at the construction field (site) are big, construction period is longer, it is a large amount of artificial to need and not green enough ring
It protects.In order to solve these problems, precast concrete also develops at the same time.
China for precast concrete explore with development start from the 1950s, until in the 1980s,
Good application is suffered from industry and civil buildings.After nineteen ninety, due to the influence of other factors, precast concrete knot
Structure in civil buildings using fewer and fewer, welcome the market of an atrophy.With the rapid advances of China's economy, to section
Can environmental protection requirement is higher and higher, continuous rise of labor cost, China is to prefabricated assembled concrete knot nearly ten years
The research of structure starts to increase.
Existing prefabricated assembled concrete structure still there is a problem of following very big:
The first, technique is backward, industrialization degree is low, product form is single, relatively backward compared to for developed country, mechanical
Chemical industry level is low, and defined quality standard is much not achieved in the component of production.Developed country, as the U.S., Canada, Japan
Deng, it is very extensive to the application of assembled architecture, up to 60 or more percent, in contrast, China is but not achieved 10%, this is just
The advantage for causing assembled architecture is difficult to play.
The second, connect difficulty, when installing at the scene because prefabricated components manufacture when tolerance, installation personnel it is skilled
Degree, connectivity problem caused by environmental factor at that time etc., there are also the difficulties for installing cross-brace beam, and precast construction is without image of Buddha steel
The such Fast Installation of frame.
Third, globality poor, fabricated globality is slightly lower compared with complete cast-in-place mode.It is mainly reflected in coupling part；
The rigidity of junction is than complete cast-in-place mode compared to lower.
Based on the above, being badly in need of designing the high precast construction system of a kind of strong globality, simple installation, rigidity.
Summary of the invention
