Technical field
The invention belongs to construction engineering technical field, the most just relate to a kind of prestressed concrete frame beam hinged joint structure, it is possible to improve the force-bearing situation of large span prestressed concrete framework.
Background technology
In architectural engineering technology, for obtaining bigger use space, prestressed concrete frame is conventional structural shape, but when building top layer uses large span prestressed concrete frame structure, axial compressive force suffered by its side framed columns is less, and moment of flexure is very big, a lot of steel bar stresses need to be configured or use the biggest column cross-section size.But frame column arrangement of reinforcement will cause reinforcing bar intensive too much, affect concrete pouring quality, costly；Increasing cross-section of frame column size, not only structure design is unreasonable, and cost is high, and also impact building is attractive in appearance and reduces building usable floor area.Therefore, the design of top layer large span prestressed concrete frame structure side column is a difficult problem urgently to be resolved hurrily in current engineering.
Summary of the invention
It is an object of the invention to the technological deficiency excessive for the large span prestressed concrete frame column stress moment of flexure in existing building engineering, a kind of large span prestressed concrete Vierendeel girder hinged joint structure is provided, top layer large span prestressed concrete framework side column is set to individual event hinged structures form, the moment of flexure that release large span prestressed concrete Vierendeel girder transmits, side framed columns is made to be in small eccentric pressure state, reduce its quantity of reinforcement and sectional dimension, improve the stress performance of frame structure, meet building large space design requirement.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of large span prestressed concrete Vierendeel girder hinged joint structure, it includes Vierendeel girder and frame column, Vierendeel girder and frame column link together composition prestressed concrete frame, it is characterized in that: described Vierendeel girder bottom surface is respectively arranged with medial septal absciss layer and lateral septal absciss layer with the inner side and outer side of frame column end face interface, described Vierendeel girder and frame column are connected by armored concrete stem stem, described armored 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, it is positioned at interior plate sealing coat side in described Vierendeel girder and is provided with armored concrete beam pad.
Further, described frame column medial surface and the main muscle of lateral surface bend anchoring at bottom elevation.
Further, described medial septal absciss layer and lateral septal absciss layer are all that tetrafluoro plate makes, and the width of tetrafluoro plate is the 1/4 of frame column height, and length is identical with frame column width, and thickness is 5mm.
Further, described armored concrete stem stem width and height are respectively frame column width and the 1/2 of height, many 4 of its main muscle quantityIn main muscle stretches into Vierendeel girder and frame column, length is not less than 30 times of main muscle diameters, and stirrup specification is not less thanStirrup spacing is 100mm.
Further, described armored concrete beam pad width is the 1/4 of frame column height, and length is identical with frame column width, and main muscle specification is not less thanStirrup spacing is 200mm.
Beneficial effect
