Description
Technical field
This utility model belongs to structural engineering field, and in particular to a kind of node of precast concrete fabricated construction
Construction.
Background technology
Building industrialization is an important development direction of current China's building field, and it not only can effectively shorten construction
Duration, moreover it is possible to a large amount of to reduce building energy consumption and building waste, building function and structural behaviour are improved, meets energy saving and environment friendly building
Idea of development.Prefabricated construction is the technical way for realizing building industrialization, precast concrete Europe,
Japan, Hong Kong are widely applied, and in recent years, precast concrete flourishes in the house of China.
At present, the fabricated construction of China is in skyscraper（50 ~ 100m or so）It is middle using less, be primarily present following asking
Topic：
1st, from from Seismic Behavior, the node in precast construction is the key for affecting structural integrity and anti-seismic performance
Position.Conventional prefabricated node generally in beam column node area, from design and construction more difficult real realization " being equal to completely cast-in-place ",
The Ductility Design of " strong node weak component " and structure " no damage in small earthquake, middle shake can be repaiied, no collapsing with strong earthquake " is required.
2nd, from the angle of construction, in conventional frame structure and frame shear wall structure, marginal frame beam generally has secondary beam
Overlap joint, generally requires to increase temporary support under construction operating mode, to avoid torsion of the marginal frame beam under construction operating mode.Interim
Support can increase operating expenses and operation, it is impossible to embody the fast superiority of fabricated construction speed of application.
3rd, it is higher to industrial requirement.Conventional prefabricated bean column node generally adopts grouting technique, and difficulty of construction is big, to behaviour
Make technical requirements high, supervision difficulty is big, the factor such as construction cost height tends not to the development for adapting to China's precast construction.
Utility model content
For above-mentioned the deficiencies in the prior art, the technical problem that this utility model is solved there is provided a kind of precast concrete
The bean column node of conventional precast construction is converted into the framework girder connection of precast concrete, by splice sections from post by framework girder connection
End is outer moves, it is to avoid splice sections are in beam column node area, therefore improve beam column node area anti-seismic performance, it is achieved thereby that " strong to save
The antidetonation theory of the weak component of point ", meets Ductility Design requirement, and solves the torsion that construction operating mode lower secondary beam overlaps marginal frame beam
Turn problem, so as to optimized construction procedure.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is as follows：A kind of precast concrete Vierendeel girder
Node, the first beam section of precast concrete Vierendeel girder and the docking of the second beam section of precast concrete Vierendeel girder, in precast concrete framework
The first party chamfer putting steel tube of the embedding level in end of the first beam section of beam；In the embedding water in end of the second beam section of precast concrete Vierendeel girder
Flat second party chamfer putting steel tube, first party chamfer putting steel tube are identical with the section of second party chamfer putting steel tube；Water is cased with second party chamfer putting steel tube
Flat slip square steel tube；Brake unit is fixed at the top of slip square steel tube, and braking dress is set at the top of second party chamfer putting steel tube
Put the opening of slip；Drive slip square steel tube to slide in second party chamfer putting steel tube by brake unit, and first party can be slid into
In chamfer putting steel tube；The Surface mulch poly tetrafluoroethylene of slip square steel tube.
Based on above-mentioned technical characteristic, as optimization, being anti-sliding stop square steel tube, torsional deflection is excessive in the square steel tube seat, builds
View slip square steel tube and first party chamfer putting steel tube and second party chamfer putting steel tube and gap no more than 10 millimeters.Brake unit can be bolt
Steel bar end or short steel plate of nail or truncate etc..
The length of slip square steel tube can be slightly less than the length of second party chamfer putting steel tube, it is proposed that slip square steel tube rests on first party
The length of chamfer putting steel tube and second party chamfer putting steel tube is roughly the same, and ensures that slip square steel tube revealed section meets the behaviour of bar connecting in beam
Make distance, the concrete of slip square steel tube revealed section can be same with overlapping top of the plate concrete scene after the completion of beam reinforced steel bar colligation
When pour.
Marginal frame beam node of this patent suitable for reinforced concrete frame structure, frame shear wall structure, from antidetonation
The aspects such as performance, convenient construction, economy, operability have larger advantage, and the popularization for precast construction provides one kind newly
Thinking.
