Technical field
The utility model is related to a kind of support connecting structure of field of civil engineering crossover, alleviates more particularly, to one kind and connects
The support connecting structure of bridging shape.
Background technology
At present, the conventional support connecting structure for crossover is：Crossover one end set it is single or two can three-dimensional turn
Dynamic fixed-hinged support, the crossover other end set it is single or two can three-dimensional rotate and can be along the slip of crossover longitudinal sliding motion
Hinged-support.For example, the support system disclosed in CN201410670965.1 patents.This bearing connected mode relatively be adapted to crossover across
Degree is small, and structure type is simple, the crossover of the linear shape of plane.
On the other hand, large span crossover has been widely used in skyscraper, plays the work of air traffic between each monomer
With while playing a part of to decorate monolithic architecture.For example, 4 between two main buildings (No. 1 building, No. 2 building) of Huaneng Group Shanghai mansion
~11 layer height scopes are connected by setting crossover, about 40 meters of crossover span.Effect is successively taken in because elevation of building has, so
Crossover is changed in the horizontal layout of each flooring.To meet architectural plane modeling requirement, the crossover plane is arcuate structure,
Middle most narrow about 3.4 meters of place, 6.7 meters of the widest part.
When crossover span is larger, and plane, facade be curved or during other irregular shapes, crossover is outside earthquake or other
Under power effect, translation, the rotational deformation that can not ignore can be produced；And concave plane cause vertical uniform load q under crossover in horizontal stroke
To the tilting moment that generation is larger.Because each monomer of skyscraper is while as crossover two ends bearing, and each list must be ensured
Body does not influence mutually under geological process, and the now translation of crossover, rotational deformation need to be given by rational bearing type of attachment
To discharge.
