The deficiencies of Ji property is poor.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution: a kind of rc-frame-beam
The shear resistance system of Column border node core space, the frame column including being located at node of column and beam core space are indulged muscle, frame column tie-bar and are located at each
Shearing resistance fashioned iron between frame column tie-bar, the shearing resistance fashioned iron are H profile steel, and the height of the H profile steel is not more than adjacent frame tie
The H profile steel layering of the distance between muscle, different directions is fixedly installed on different frames column tie-bar, the both ends of the H profile steel
Frame column is stretched out respectively, is extend into corresponding Vierendeel girder and is indulged muscle with the Vierendeel girder in Vierendeel girder, frame beam stirrup is fixedly connected.
Preferably, the shearing resistance fashioned iron is narrow edge of a wing H profile steel.
Preferably, the installation site of the shearing resistance fashioned iron is located on the central axes of associated frame members beam.
Preferably, it uses and is welded and fixed between the shearing resistance fashioned iron and frame column tie-bar.
Preferably, frame column is stretched out at shearing resistance fashioned iron both ends, extend into the part of Vierendeel girder and Vierendeel girder indulges muscle, frame
It uses and is welded and fixed between beam stirrup.
Compared with the existing technology, the utility model has the following beneficial effects: the utility model meets the base of seismic design of structures
The shearing resistance fashioned iron of this principle, different directions plays shearing resistance effect to the Vierendeel girder of different directions respectively, effective to improve node core
The shear-carrying capacity of heart district reduces the configuration amount of core space frame column tie-bar, and joint structure is simple, is easy to construct, and cost is relatively low,
It can be good at guaranteeing construction quality.
Detailed description of the invention
Fig. 1 is the joint cores horizontal sectional drawing of the utility model；
Fig. 2 is the I--I cross-sectional view of Fig. 1.
In figure: 1, frame column indulges muscle 2, frame column tie-bar 3, shearing resistance fashioned iron 4, Vierendeel girder 5, frame column 6, frame
It sets a roof beam in place vertical muscle 7, frame beam stirrup.
Specific embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of shear resistance system of beam-column joint of reinforced concrete frame core space, including
Positioned at node of column and beam core space frame column indulge muscle 1, frame column tie-bar 2 and be located at each frame column tie-bar) between shearing resistance fashioned iron 3,
The beam column node core area is the overlapping region of Vierendeel girder 4 Yu frame column 5, is the node region that beam column crosses, and is that beam column passes
The key position of power, the shearing resistance fashioned iron 3 are H profile steel, and the height of the H profile steel is no more than between adjacent frame column tie-bar 2
The H profile steel layering of distance, different directions is fixedly installed on different frames column tie-bar 2, and the both ends of the H profile steel are stretched out respectively
Frame column 5 extend into corresponding Vierendeel girder 4 and indulges muscle 6 with the Vierendeel girder in Vierendeel girder 4, frame beam stirrup 7 is fixedly connected；It is excellent
Choosing, the shearing resistance fashioned iron 3 is narrow edge of a wing H profile steel；Preferably, the installation site of the shearing resistance fashioned iron 3 is located at associated frame members beam 4
Central axes on；Preferably, it uses and is welded and fixed between the shearing resistance fashioned iron 3 and frame column tie-bar 2；Preferably, the shearing resistance
