It is correspondingly provided with the steel column edge of a wing and angle steel for the bolt hole through bolt, the angle steel is arranged between the edge of a wing of girder steel two and one
While being connected by bolt with steel beam web plate, another side is linked together end plate and the steel column edge of a wing by bolt.
Further, the i-shape steel beam is welded by steel plate.
Further, the i-shape steel beam is rolled section steel.
Further, the H profile steel post is welded by steel plate.
Further, the H profile steel post is rolled section steel.
Further, the bolt is high strength stainless steel bolt.
The beneficial effects of the utility model are：
(1) it is capable of the security and globality of effective guarantee structural system, adds ductility, the fire-resistance energy of steel join domain
Power and energy dissipation capacity.
(2) node includes two kinds of connection types (varied rigid link and flexible connection), is provided simultaneously with two kinds of failure mechanisms,
Allow beam-ends end plate to be destroyed in extreme load operating mode, preferable deformability and fire endurance are provided by flexible connection.
(3) being connected using assembling type steel structure, component is prefabricated in the factory, and production quality is high, and live quick assembling can be achieved,
Save the duration.
Assembling type steel structure connection stress performance is superior, high-rise available for Fire-resistance of Steel Structures system and high intensity Zone
In steel building, there is more wide application prospect.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing illustrates：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of girder steel；
Fig. 3 is the structural representation of steel column；
Fig. 4 is the structural representation of angle steel；
Fig. 5 is the structural representation of end plate.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As illustrated, the assembled connecting node in the utility model, including girder steel 1, steel column 2, in addition to angle steel 3, end
Plate 4 and bolt 5, wherein girder steel 1 are i-shape steel beam, and steel column 2 is H profile steel post, and angle steel 3 and bolt 5 are stainless steel；Institute
End plate 4 is stated as flush end plate and is welded on the end of girder steel 1, is correspondingly set on the steel beam web plate, end plate, the steel column edge of a wing and angle steel
Have and be arranged on for the bolt hole 6 through bolt 5, the angle steel 3 between the edge of a wing of girder steel two and while by bolt 5 and girder steel
Web is connected, and another side is linked together end plate 4 and the steel column edge of a wing by bolt 5.
In the utility model, existing welding between girder steel 1 and end plate 4, have again by stainless steel angle steel and stainless steel bolt
Secondary connection, it is then corresponding between girder steel 1 and steel column 2 to be got up by stainless steel bolt, welded end plate and stainless steel Bolted angle connection.One side
Face, i-shape steel beam 1 employ two kinds of different steel materials, including common iron and fire resistance from the connected mode of H profile steel post 2
Stainless steel material, so as to strengthen the deformability and refractory ability of steel connection.On the other hand, i-shape steel beam 1 and H profile steel post 2
Connected mode employ Composite steel connections type, while include varied rigid link and be articulated and connected two kinds of connection types.
The connected mode overcomes conventional node under high temperature action because weld residual stress and heat-affected zone influence hair
Cast steel plate junction cracking phenomena；Because angle steel 3 and bolt 5 are stainless steel, ductility and the Shandong of steel join domain are enhanced
Rod so that under fire effect, node end plate also possesses enough ductility conversion force-mechanism formation two even if destruction occurs
Secondary protective capacities, i.e., plastic hinge is formed at girder steel both ends, substantially increase the cooperative transformation ability of i-shape steel beam, form stretched wire
Property effect ensure structure Progressive Collapse will not occur；After having ensured that connecting node is destroyed in end plate weld joint region, even
Node is connect still to work in an articulated manner.The connection joints of steel structure can be used for antidetonation region, utilize stainless steel angle
The excellent ductility of steel, deformability and secondary protection mechanism, dissipate excess energy under earthquake load or reciprocating load,
Ensure the security and globality of structure.
I-shape steel beam and H profile steel post in the utility model can be welded by steel plate, can also use rolled section steel.Can
It is mounted directly at the scene, speed of application is very fast and structure manufacture quality is high.
Preferably, bolt is high strength stainless steel bolt, can further improve bolt performance.
I-shape steel beam and H profile steel post are welded by steel plate in the present embodiment, and its linkage editor is as follows：
A. i-shape steel beam 1 is welded into steel plate in factory, and bolt hole 6 is opened on steel beam web plate；
B. H profile steel post 2 is welded into steel plate in factory, and bolt hole, diameter of bolt hole and position is opened on the steel column edge of a wing
It is consistent with the bolt hole on i shaped steel beam end plate；
C. in 4 one pieces of factory's cutting rectangle end plate, and bolt hole is opened on end plate, bolt hole position and diameter and H profile steel
Post upper bolt hole is consistent；End plate 4 is welded in the perforate side one end of i-shape steel beam 1, and by its center alignment；
D. make stainless steel angle steel 3 in factory, and bolt hole opened on angle steel, bolt hole position and diameter respectively with steel column
Bolt hole position and size on the edge of a wing and steel beam web plate are consistent；
E. stainless steel angle steel 3, flush end plate 4 and the H profile steel post edge of a wing are connected respectively with stainless steel bolt 5, and connect steel
Web.
Generally speaking, the node overcomes conventional node and easily occurred in fire and with solder design region under geological process
The deficiency of destruction, by using two kinds of different steel and two kinds of failure mechanism patterns, complement each other, ensured steel structure system
Globality and integrality, available in fire-resistance and high intensity Zone steel structure system.Using assembled in situ formula construction method, go back
Help to save the duration.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
