There is Vierendeel girder concrete；Described concrete ring beam include being centered around ring beam ring muscle outside compound round steel pipe confined concrete models with
And the ring beam stirrup being centered around on reinforced beam, described ring beam ring muscle and ring beam stirrup have poured ring beam concrete, and
Between ring beam concrete with the steel pipe of outer steel pipe indentation, there, concrete is connected.
Described ring beam ring muscle uses circular steel bar butt welding to form.
Described ring beam stirrup and ring beam ring muscle colligation form entirety.
The gap of 10mm is left in the described outer upper and lower both sides of steel pipe breach away from reinforced beam.
Described Vierendeel girder is indulged muscle and is formed entirety with Vierendeel girder stirrup colligation.
Described reinforced beam is evenly arranged with four in compound round steel pipe confined concrete models shaft surrounding.
Compared with prior art, this utility model, by offering breach on the outer steel pipe of compound round steel pipe confined concrete models, makes
Obtain outer steel pipe and do not directly take on xial feed, only core space concrete is played effect of contraction, effectively prevent steel pipe at axial masterpiece
Cripling with lower generation so that the examining tensile behavior of steel excellence is farthest played.The compound round steel of this utility model
Within pipe confined concrete models, steel pipe substitutes the steel reinforcement cage in the past used, owing to steel pipe itself can simplify construction as template
Operation, is prevented effectively from the overstocked concreting caused of arrangement of reinforcement simultaneously and vibrates difficulty so that the pouring quality of concrete is guaranteed.
It is provided with concrete ring beam, it is to avoid outer steel pipe may be at breach on the shaft of this utility model compound round steel pipe confined concrete models
Place disconnects the weakening caused so that node area intensity is improved, thus meets the design criteria of " strong node, weak component ".
The interior steel pipe of this utility model compound round steel pipe confined concrete models is filled core concrete, fills between interior steel pipe and outer steel pipe
Concrete between steel pipe, it is possible to effectively make up sky steel pipe flexing unstability and the short slab of fire protecting performance difference, add the reliability of component.
This utility model effectively prevent indulges blocking or through steel pipe, maintaining the globality of component so that node of muscle in beams of concrete
Flexural property and anti-seismic performance be significantly improved.This utility model can give full play to steel and concrete on the whole
Each advantage, its bearing capacity is higher, and anti-seismic performance is good, and construction is simple easily, it is ensured that construction quality, remarkable in economical benefits.
