In view of this, it is an object of the invention to provide a kind of assembled connecting node, to improve the peace of steel structure connection
Full property and energy dissipation capacity.
To reach above-mentioned purpose, the present invention provides following technical scheme：A kind of assembled connecting node, including girder steel, steel
Post, in addition to angle steel, end plate and bolt, the girder steel are i-shape steel beam, and the steel column is H profile steel post, the angle steel and spiral shell
Bolt is stainless steel；The end plate is flush end plate and is welded on girder steel end, the steel beam web plate, end plate, steel column
It is correspondingly provided with the 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 while logical
Cross bolt to be connected with steel beam web plate, another side is linked together end plate with 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 present invention 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) connected using assembling type steel structure, component is prefabricated in the factory, make quality height, scene 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, with more wide application prospect.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out
Explanation：
Fig. 1 is structural representation of the invention；
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, the preferred embodiments of the present invention are described in detail.
As illustrated, the assembled connecting node in the present invention, 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；The end
Plate 4 is flush end plate and is welded on the end of girder steel 1, the steel beam web plate, end plate, the steel column edge of a wing and angle steel and is correspondingly provided with use
In the bolt hole 6 through bolt 5, the angle steel 3 is arranged between the edge of a wing of girder steel two and while connected by bolt 5 and steel beam web plate
Connect, another side is linked together end plate 4 with the steel column edge of a wing by bolt 5.
In the present invention, existing welding between girder steel 1 and end plate 4 has by the secondary of stainless steel angle steel and stainless steel bolt again
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.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 common iron and fire resistance are not
Become rusty 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 employs Composite steel connections type, while including varied rigid link and the two kinds of connection types that are articulated and connected.
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.
I-shape steel beam and H profile steel post in the present invention can be welded by steel plate, can also use rolled section steel.Can be existing
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 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. make stainless steel angle steel 3 in factory, and open on angle steel bolt hole, bolt hole position and diameter respectively with steel column
Bolt hole position and size on wing Edge and steel beam web plate are consistent；
E. stainless steel angle steel 3, flush end plate 4 and H profile steel post wing Edge 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, complements each other, has 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, also
Help to save the duration.
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.
