Description
Technical field
The present invention relates to concrete construction technical field, specifically a kind of precast concrete frame beam structure.
Background technology
With the fast development and the continuous quickening of urbanization process of Chinese national economy, the contradiction of building trade is also more next
It is more：High energy consumption, cost increase, construction site it is filthy etc., inefficient extensive method is hard to carry on, in recent years
Come, China carries forward vigorously building industrialization and housing industrialization.Precast Concrete Frame system meet building industrialization and
The requirement of the green building of housing industrialization.Such structural system has the advantages that speed of application is fast, environmental pollution is small.
Frame structure is the most widely used structure of construction industry, and it can also group with shear wall structure, tube structure etc.
Resultant frame shear wall system, frame-tube system, therefore, will promote precast construction assembling system, study pre-fabricated one
In beam column between connected mode it is particularly necessary, it is well known that frame structure can overall work, frame column and Vierendeel girder it
Between be reliably connected it is very crucial；Conventional concrete construction continuously arranged due to concrete cast-in-situ, node region steel bar stress, only
Rational reinforcing bar is configured, is typically not in the destruction connected between component, but actually applying in precast concrete
During work, the construction positioning at prefabricated components bean column node is not easy, therefore reduces speed of application and efficiency；For prefabricated
For concrete structure, whether the quality of connection of component can be guaranteed, and be that can total play the key of design function
Place, and the shear-carrying capacity and ductility generally at precast construction bean column node are poor, easily become the weakness in structural system
Position, so that the security to whole precast construction threatens, some achievements in research are also indicated that, fabricated assembly overall structure
Anti-seismic performance it is poor compared with cast-in-place concrete structure.
The content of the invention
For above technological deficiency, manufacture that difficulty is low, convenient, connection of constructing it is an object of the invention to provide one kind
The simple precast concrete frame beam structure of form, not only shortens construction period, reduces cost, and the traditional precast beam avoided
This stress weakness zone of Column border node.
Technical scheme is as follows：
A kind of precast concrete frame beam structure, including precast concrete beam, precast concrete bean column node, beam longitudinal reinforcement,
Node longitudinal reinforcement and welded reinforcement, it is characterised in that：The two ends of the precast concrete beam are provided with the concrete
Native bean column node, beam longitudinal reinforcement and node are worn inside the precast concrete beam, precast concrete bean column node respectively
Longitudinal reinforcement, the beam longitudinal reinforcement and node longitudinal reinforcement stretch out precast concrete beam, precast concrete bean column node respectively
End, the welded reinforcement by stretch out the precast concrete beam, precast concrete bean column node end beam longitudinal reinforcement
Mutually overlap, fixed in lap-joint by casting concrete with node longitudinal reinforcement.
Specifically, the beam longitudinal reinforcement and node longitudinal reinforcement extension curve U-shaped, the beam longitudinal reinforcement and section
Interlaced be stacked to form hollow structure between the U-shaped of point longitudinal reinforcement, and the welded reinforcement is vertically penetrated in hollow structure simultaneously
It is welded to each other with beam longitudinal reinforcement and node longitudinal reinforcement, pad is located at the curved of the beam longitudinal reinforcement and node longitudinal reinforcement
At folding.
Specifically, the welded reinforcement and beam longitudinal reinforcement, node longitudinal reinforcement lap-joint are apart from precast concrete beam column
The beam section effective depth of 1.5-2 times of node top surface, its lap of splice is identical with stirrup spacing.
Specifically, post-cast strip is left at the two ends of the precast concrete beam, described post-cast strip length is between twice of stirrup
Away from.
Setting post-cast strip can prevent that precast concrete beam and overall structure from producing because autogenous shrinkage is uneven or sedimentation is uneven
Harmful cracks.
Specifically, the strength of materials that pours that the post-cast strip is used pours the strength of materials more than precast concrete beam.
The beneficial effect of the invention is：
（1）Connection at usual precast concrete bean column node is weaker, and Seismic Behavior is poor, and present invention obviates this
Weakness zone, maintains the globality and anti-seismic performance of bean column node while having precast construction simple structure, stress is clear and definite
Feature.
（2）Compared with traditional prefabricated components, connected mode adaptability of the invention is stronger, not special to bar material
It is required that, using this more ripe construction means instantly is welded, difficulty of construction is low, cheap.
（3）The fractionation position of beam is selected in girder span near inflection point, weak part is avoided internal force maximum, improves knot
Security under structure normal operating conditions.

Precast concrete beam 1, precast concrete bean column node 2, beam longitudinal reinforcement 3, welded reinforcement 4, node longitudinal reinforcement 5.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As illustrated in the accompanying drawings from 1 to 3, including precast concrete beam 1, precast concrete bean column node 2, beam longitudinal reinforcement 3 welding steel
Muscle 4 and node longitudinal reinforcement 5.Such as Fig. 1, precast concrete bean column node 2 is arranged on the two ends of precast concrete beam 1, prefabricated mixed
Beam longitudinal reinforcement 3 and node longitudinal reinforcement 5, beam longitudinal reinforcement 3 are worn respectively inside solidifying soil beam 1, precast concrete bean column node 2
Stretch out the end of precast concrete beam 1, precast concrete bean column node 2 respectively with node longitudinal reinforcement 5.
As shown in figs. 4 through 6, welded reinforcement 4 will stretch out precast concrete beam 1, precast concrete bean column node 2 end
Beam longitudinal reinforcement 3 and node longitudinal reinforcement 5 mutually overlap.The present embodiment is as preferred, by beam longitudinal reinforcement 3 and section
The point extension of longitudinal reinforcement 5 curves U-shaped, interlaced between beam longitudinal reinforcement 3 and the U-shaped of node longitudinal reinforcement 5 to be stacked shape
Into hollow structure, welded reinforcement 4 is vertically penetrated in hollow structure and is welded to each other with beam longitudinal reinforcement 3 and node longitudinal reinforcement 5,
Pad is located at the bending place of beam longitudinal reinforcement 3 and node longitudinal reinforcement 5；The precast concrete bean column node 2 so set is kept away
Bean column node weak in traditional pre-fabricated one has been opened, and this kind is located at the Vierendeel girder inflection point under normal operating conditions
Place, it is more reasonable to construct.
Welded reinforcement 4 is with beam longitudinal reinforcement 3, the lap-joint of node longitudinal reinforcement 5 apart from the top surface of precast concrete bean column node 2
