Description
Technical field
The present invention relates to a kind of prefabricated panel and overlapping beam connecting node and its construction methods, belong to assembled architecture technology
Field.
Background technique
In assembled architecture system, due to surpassing the layer height of most of Gongjian's projects (such as school, office building project)
3.2m is crossed, beam span is greater than 6m, if using the pre- of Liang Qiang one (prefabricated panel and composite beam are integral prefabricated in pre-fabricated factory)
Component processed produces one hem width degree of steel trolley (platform mould) limiting member of prefabricated panel since the size of beam is too big under normal conditions
3.2m cannot be greater than, the existing pre-fabricated factory for generating prefabricated panel will be difficult to produce such prefabricated components, and need to production line
It improves, prefabricated components transport also by biggish limitation, will increase transportation cost, and the prefabricated components self weight of Liang Qiang one
Larger, the length direction along beam cannot be split again, and self weight is unfavorable for greatly very much the lifting operation during construction in later period, and increase is applied
Work cost.
