Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As illustrated, the endplate connections node in the present invention, including girder steel 1, steel column 2, angle steel, end plate 4 and bolt 5,
The girder steel 1 is i-shape steel beam, and the steel column 2 is H profile steel post, and the end plate 4 is welded on the end of girder steel 1, and the end plate 4 is
Endplate connections, the angle steel includes L-type angle steel 3 and top-seat-angle steel 7, and the L-type angle steel 3, top-seat-angle steel 7 and bolt 5 are
Stainless steel；It is correspondingly provided with the web of girder steel 1 and the edge of a wing, end plate 4, the edge of a wing of steel column 2 and angle steel for through bolt
Bolt hole 6, the L-type angle steel 3 is arranged between the web of girder steel 1 and end plate 4, and the one side of L-type angle steel 3 passes through bolt 5 and the web of girder steel 1
Connection, another side is connected by bolt 5 with end plate 4 and the edge of a wing of steel column 2；The top-seat-angle steel 7 has two, is correspondingly arranged at steel
The edge of a wing both sides of beam 1, one side of each top-seat-angle steel 7 is connected by bolt 5 with the edge of a wing of girder steel 1, and another side passes through bolt 5 and end plate 4
And the edge of a wing of steel column 2 is connected.
In the present invention, existing welding between girder steel 1 and end plate 4 has by stainless steel L-type angle steel, stainless steel top-seat-angle steel again
And the secondary connection of stainless steel bolt, it is then corresponding between girder steel 1 and steel column 2 to pass through stainless steel bolt, welded end plate and two kinds of angle steel
Connect.On the one hand, i-shape steel beam 1 employs two kinds of different steel materials from the connected mode of H profile steel post 2, including general
Logical steel (girder steel, steel column and end plate) and fire resistance stainless steel material (angle steel and bolt), so as to enhance the deformation of steel connection
Ability and refractory ability.On the other hand, the connected mode of i-shape steel beam 1 and H profile steel post 2 employs Composite steel connections type,
Including two kinds of connection types of varied rigid link and flexible connection, two kinds of failure mechanisms are provided simultaneously with.
The connected mode overcomes conventional node under high temperature action because of 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 occurring destruction
Secondary protective capacities, i.e., form plastic hinge at girder steel two ends, substantially increases the cooperative transformation ability of i-shape steel beam, forms stretched wire
Property effect ensure structure will not occur Progressive Collapse；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.

Field is mounted directly, and speed of application is very fast and structure manufacture quality is high.
It is preferred that, 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 opens on steel beam web plate and the edge of a wing bolt hole 6；
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 steel column wing Edge
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, bolt hole position and diameter and H profile steel are opened on end plate
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. stainless steel L-type angle steel 3 and top-seat-angle steel 7 are made in factory, and bolt is opened on L-type angle steel 3 and top-seat-angle steel 7
Hole, bolt hole position and diameter are kept with the bolt hole position on steel column wing Edge and steel beam web plate, steel beam flange and size respectively
Unanimously；
E. stainless steel L-type angle steel 3, top-seat-angle steel 7, endplate connections 4 and H profile steel post are connected respectively with stainless steel bolt 5
Wing Edge, and connect steel beam web plate and the edge of a wing.
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, complements each other, has ensured steel structure system
Globality and integrality, available in fire-resistance and high intensity Zone steel structure system；By L-type angle steel and top-seat-angle steel to steel
Beam and endplate connections change on secondary connection and joint form, and the bending bearing capacity of the node is greatly improved
And rigidity, rigid joint hypothesis can be done.Using assembled in situ formula construction method, the saving duration is additionally aided.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
