Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of large span prestressed concrete Vierendeel girder hinged joint structure, it comprises Vierendeel girder and frame column, Vierendeel girder and frame column link together composition prestressed concrete frame, it is characterized in that: the inner side and outer side of described Vierendeel girder bottom surface and frame column end face interface is respectively arranged with medial septal absciss layer and lateral septal absciss layer, described Vierendeel girder is connected by steel concrete stem stem with frame column, described steel concrete stem stem is between medial septal absciss layer and lateral septal absciss layer, Vierendeel girder is stretched in one end, the other end stretches into frame column, be positioned at interior plate separation layer side in described Vierendeel girder and be provided with steel concrete beam pad.
Further, described frame column medial surface and the main muscle of lateral surface are in the bending anchoring of bottom elevation place.
Further, described medial septal absciss layer and lateral septal absciss layer are all that tetrafluoro plate makes, and the width of tetrafluoro plate is 1/4 of frame column height, and length is identical with frame column width, and thickness is 5mm.
Further, described steel concrete stem stem width and be highly respectively frame column width and height 1/2, many 4 of its main muscle quantity
main muscle stretches into length in Vierendeel girder and frame column and is not less than 30 times of main muscle diameters, and stirrup specification is not less than
stirrup spacing is 100mm.
Further, described steel concrete beam pad width is 1/4 of frame column height, and length is identical with frame column width, and main muscle specification is not less than
stirrup spacing is 200mm.
Beneficial effect
