Description
Technical field
The utility model belongs to steel building field, more particularly to a kind of beam column of steel structure by tilting end plate connection
Connecting node.
Background technology
Because steel construction has repeatable utilization, building waste is few, environmental pollution is small, the quick advantage of easy construction, steel
The intensity of structural construction structure is high, and plasticity is big, good-extensibility, solderability are strong, anti-seismic performance is good, meets China and the world is sustainable
Demand for development, this just makes steel building application more and more universal, but while steel construction is fast-developing, some important steel
Structural Engineering collapse accident, causes the concern of common people, so, promote the sound development of China's construction steel structure very necessary.And
Bean column node is easiest to the place being broken in being destroyed as steel construction, become the key during Construction of Steel Structure makes, mesh
Before, end plate connection is conventional beam-to-column joint, i.e., be first welded on the flange plate of post and be vertically welded in beam by end plate in factory
End, then pass through high-strength bolt joint connection in site.This connection has problems with：Because the pressure at right angle on beam is direct
Post is passed to by the friction between beam end plate and styletable plate, so intensity to high-strength bolt and end plate welded seam has very
High requirement, maximum stress at node side plate weld near, be easier to when the disasters such as earthquake occur to occur node
Brittle break.
Utility model content
The utility model aims to solve the problem that above mentioned problem there is provided one kind connection is safe and reliable, and intensity is high, and ductility is big, be difficult by
The steel structure girder column connected node by tilting end plate connection of destruction.Avoid and excessively concentrated because header portion stress is excessive
And the node brittle break caused.
The technical solution adopted in the utility model is：
A kind of steel structure girder column connected node by tilting end plate connection, including steel column 1 and girder steel 2, it is characterised in that：
Steel column 1 and girder steel 2 end is in 45 degree of ramped shapeds, through each vertical welding one of groove full penetration weld on its 45 degree of inclined-planes
Block end plate 3, two pieces of identical end plates 3 are linked together by high-strength bolt 5, are welded between end plate and steel column web and steel beam web plate
Stiffener 6 is connected to, support bar 7 is provided between steel column 1 and girder steel 2, described one end of support bar 7 passes through connecting plate 8 and bolt
It is connected on steel column flange plate, the other end is by connecting plate 8 and is bolted on steel beam flange plate, level in the steel column 1
Two groups of sash ribs 4 are provided with, one group intersects at the 50mm of lower section positioned at end plate 3 with steel column right flank listrium, and one group is located at support
Two pairs of ribbed stiffeners 4 are vertically arranged with the axis of bar 7 and steel column right flank listrium junction, the girder steel 2, one group is located at end plate 3
Intersect with girder steel bottom wing listrium at the 50mm of right, one group is located at the axis of support bar 7 and girder steel bottom wing listrium junction, described to add
Welded between strength rib 4 and steel column steel beam flange, web using groove full penetration weld.
Further, the steel column 1 and girder steel 2 are H profile steel, and support bar 7 is square steel.
Further, the support bar 7 welds together with connecting plate 8.
The utility model compared with prior art, with following advantage：
Structure connection end plate is 45 degree and is obliquely installed, it is possible to reduce the design shear of node, can utilize the pressure of post
Strong effect to joints.When moment of flexure is larger, the arm of force of moment connection can be lengthened by tiltedly putting end plate, be conducive to arranging spiral shell
Bolt.Support bar is set between steel column and girder steel, a part of power on node has been decomposed, stress concentration can be effectively solved and show
As preventing node because stress is excessive and causes destruction.So as to improve the overall security and stability of steel construction.
