And be truncated thus being formed for facilitating the installation of web 2-1 and connecting plate 4 described in bolt connection auxiliary at the 1-2 of the post edge of a wing
Help breach, be provided with described installation additional notches and supply steel plate 6 for the flange of beam closed, described flange of beam supplies steel
One end of plate 6 is fixedly connected with flange of beam 2-2, and the other end that described flange of beam supplies steel plate 6 is fixedly connected with post edge of a wing 1-2,
Described flange of beam is supplied steel plate 6 and is fixedly connected with two web 2-1.
In the present embodiment, the left and right two ends of described internal partition 3 are corresponded with two post edge of a wing 1-2 and are welded to connect, described
The rear and front end of internal partition 3 is corresponded with two column web 1-1 and is welded to connect；Described connecting plate 4 is with post edge of a wing 1-2 welding even
Connect；Described flange of beam supplies one end of steel plate 6 and flange of beam 2-2 is welded to connect, described flange of beam supply the other end of steel plate 6 with
Post edge of a wing 1-2 is welded to connect, and described flange of beam is supplied steel plate 6 and is welded to connect with two web 2-1.
In the present embodiment, the connecting node of this box-girder and box column can effectively realize the company of box column 1 and box-girder 2
Connect, so that the good torsional rigidity of box-girder 2 and the good compressive property of box column 1 are perfectly combined together, concrete
During construction, large span can be accomplished, architectural can obtain large space.
In the present embodiment, by arranging horizontal layout and corresponding internal partition 3 by node with the position of flange of beam 2-2
Box-shaped is closed in domain, becomes reinforced nodes domains, by arranging connecting plate 4, and by multiple bolts 5 by web 2-1 and company
Fishplate bar 4 is connected, then flange of beam is supplied steel plate 6 and post edge of a wing 1-2 and flange of beam 2-2 and web 2-1 welding.So,
By easy building method, improve nodes domains, improve ultimate bearing capacity of joints and anti-seismic performance, meet national design specification requirement
The aseismatic design concept of " strong node, weak component ".
In the present embodiment, facilitate described web 2-1 by setting installation additional notches and the bolt of connecting plate 4 connects
Connect, after web 2-1 and connecting plate 4 bolt connection, then with flange of beam supply steel plate 6 by described installation additional notches envelope
Close, described flange of beam is supplied steel plate 6 and welded with flange of beam 2-2 and post edge of a wing 1-2 and web 2-1 phase, further enhancing

In the present embodiment, described column web 1-1 and post edge of a wing 1-2 are all welded to connect with internal partition 3, described connecting plate 4 with
Post edge of a wing 1-2 is welded to connect.
As shown in figure 3, described flange of beam is supplied offers multiple through hole 6-1 for weakening its rigidity on steel plate 6.Building
Build in Aseismic Design, generally using the aseismatic design concept of " strong node, weak component ", under this theory, when eaerthquake damage, structure
Part produces prior to connecting node and destroys, and, leads to that is to say, that the deformation of box-girder 2 stands in the breach specific in the present embodiment
Cross the deformation of box-girder 2 to absorb seismic energy, thus protecting whole building thing not collapse.In the present embodiment, in flange of beam
Supply and through hole 6-1 is opened up on steel plate 6 to reach the purpose that reduction flange of beam supplies steel plate 6 rigidity.When there is earthquake, due to setting
Being equipped with the flange of beam of multiple through hole 6-1, to supply steel plate 6 rigidity weaker, can be deformed first, produce under earthquake potential damage
The flange of beam of the shape that changes is supplied steel plate 6 and can be absorbed seismic energy, thus effectively avoiding box column 1 and this connecting node to produce
Destroy, and then protect the safety of whole building structure.That is, steel plate 6 is supplied using described flange of beam can reach " by force
The aseismatic design concept of node, weak component ", actively can absorb seismic energy by deformation.
As shown in figure 4, the edge part that described flange of beam supplies steel plate 6 offers the side notch 6- for weakening its rigidity
2.Supply setting side notch 6-2 on steel plate 6 in flange of beam, its purpose is the same with setting through hole 6-1, by weakening the beam wing
Edge supplies the rigidity of steel plate 6, thus realizing under eaerthquake damage, flange of beam is supplied steel plate 6 and produced destruction prior to box-girder 2, from
And be effectively protected box-girder 2, and then protect the safety of whole building structure.
In the present embodiment, described through hole 6-1 can be circular, square, oval or other shapes.Described side notch 6-
2 can be arc or other shapes.
In the present embodiment, described flange of beam supply steel plate 6 along box-girder 2 bearing of trend length a be 500mm～
1000mm.So it can be avoided that in earthquake, flange of beam supplies the weld seam that steel plate 6 supplies steel plate 6 and flange of beam 2-2 from flange of beam
Place produces and destroys.If flange of beam supply steel plate 6 along box-girder 2 bearing of trend length be less than 500mm when, in earthquake, beam
The commissure generation destruction that steel plate 6 can supply steel plate 6 and flange of beam 2-2 from flange of beam is supplied on the edge of a wing, effective from being unable to
Absorb seismic energy.If flange of beam supply steel plate 6 along box-girder 2 bearing of trend length be more than 1000mm when, can be to case
The load-carrying properties of ellbeam 2 cause to damage.
As shown in Fig. 2 described connecting plate 4 is arranged on the inner side of described web 2-1.So connecting plate 4 can be protected
Inside box-girder 2, connecting plate 4 can be effectively protected, and then ensure that this connecting joint structure is complete and box column 1 He
The effectively connection of box-girder 2.
