Specific embodiment
Referring to Fig. 1 to Fig. 7, a kind of pretensioned prestressing integral precast structure that the utility model provides, including band bolumn cap
Reinforced concrete pile 1, Two bors d's oeuveres prestressing force overlapping girder 2, prestressing force overlapping secondary frame beam 3, prestressing force overlap secondary beam 4, steel floor support plate group
Floor 5 is closed, it is characterized in that bolumn cap 11 section of the reinforced concrete pile 1 with bolumn cap at bean column node is greater than column section, bolumn cap
Top extends to plate face, and bolumn cap lower part extends to the following certain length in girder lower surface；The Two bors d's oeuveres prestressing force overlapping girder 2 wraps
It includes by pouring reinforced concrete part 22 behind two pretensioned prestressing precast beams 21 arranged side by side and top, pretensioned prestressing precast beam
Side is equipped with and shelves notch 23；After the prestressing force overlapping secondary frame beam 3 is including single pre-tensioning system precast beam 31 and with plate thickness
Reinforced concrete part 32 is poured, Two bors d's oeuveres prestressing force overlaps the prefabricated beam portion of pretensioned prestressing of girder 2 and prestressing force overlapping secondary frame beam 3
Divide and protrudes into certain length in bolumn cap 11；The prestressing force overlapping secondary beam 4 includes single pretensioned prestressing precast beam 41 and same plate
Pour reinforced concrete part 42 after thick, 41 both ends of pretensioned prestressing precast beam, which are equipped with to shelve, takes the lead 411, shelves to take the lead and 411 protrude into
Girder precast beam is shelved in notch 23；The steel floor support plate composite floor 5 includes that silent floor support plate 51 or steel bar girder building are held
