Description
Technical field
The invention belongs to crossover technical field of structures, more particularly, to a kind of streptostyly resistance to plucking structure for crossover.
Background technique
With the propulsion of urbanization and rich and varied, the crossover between building and the people across street of high-rise shape
Row overline bridge is very universal.Due to the requirement of building shape, special-shaped crossover becomes more and more, and is located at the high position for building high area
Crossover is also very universal.
Since usual span is larger, expansion and contraction under action of thermal difference must be considered crossover structure；It is located at
Crossover between two or more solitary buildings, other than the effect of common working load, it is also necessary to consider technical measures appropriate
Cause to occur mutually to involve effect between main building to avoid the presence due to crossover, the above two o'clock determines that crossover is commonly designed
Fixed as one end, one end sliding or both ends allow the force modes of the sliding under finite stiffness, no matter it is above-mentioned which kind of by
Force mode, current crossover are generally designed to the mode being shelved on bridge pier or main building structural column by support.
In actual use, special-shaped crossover and high-order crossover are under load action, especially under wind load and geological process,
Pulling capacity is usually easy at support, under set up defences earthquake and severe earthquake action, the pull out force of support would generally be apparent；Even if designing
Cheng Zhong does not occur pulling capacity from calculated result, but due to the uncertainty of lateral load, especially earthquake load, crossover is drawn
Pull out force is also required to be taken into account in the design；If crossover shelves pulling capacity a little cannot be transmitted to bridge pier or master well
Upstairs, the danger that even pontic topples etc. then crossover is easy to misplace there are support.
Crossover finished product support includes plate bearing, spherical steel support, lead core rubber support, friction pendulum support etc. at present.This
A little supports have unidirectional and bidirectional parallel operating characteristic, and some of them are also equipped with certain horizontal rigidity, and it is sliding to adapt to crossover structure
Characteristic is moved, wherein plate bearing, friction pendulum support do not have breakout capacity, cannot be used in and shelve in the crossover for a little having pulling capacity；
Spherical steel support, lead core rubber support have certain breakout capacity, but the limitation of the size and height of support itself makes resistance to plucking
Power is limited, and there are comparable not true since the difference of producer's quality control capability makes the practical breakout capacity of finished product support
It is qualitative.
