Abstract
The utility model discloses a novel dog-bone type beam column joint which comprises a steel stand column and a #-shaped steel plate. The steel stand column is a square steel tube, wherein the four side faces of the square steel tube are respectively provided with two bar-shaped steel plate holes, and steel angles are further fixedly connected to the positions, above the two steel plate holes and under the two steel plate holes, of the square steel tube. The #-shaped steel plate is inserted into the steel plate holes, and dog-bone type steel beams are connected with the plate ends of the #-shaped steel plate. The #-shaped steel plate and the dog-bone type steel beams are connected through high-strength bolts, and the dog-bone type steel beams and the steel angles are connected through high-strength bolts. The steel stand column and the dog-bone type steel beams form one beam column joint, wherein the cross section of the beam column joint is similar to a cross shape. The novel dog-bone type beam column joint is simple in structure and convenient to mount and maintain, and has high bending moment bearing capacity and high plastic rotation capacity.
Description
Technical field
The utility model relates to a kind of bean column node, relates in particular to a kind of novel dog bone type bean column node.
Background technology
Steel work is because the design of bean column node junction is unreasonable, can produce serious earthquake during macroseism, the Japanese slope of the USA Northridge Earthquake of 1994 and nineteen ninety-five is earthquake centre celestially, high-rise steel structure house, hundreds of building is subject to destructive infringement because bean column node destroys, therefore, modern architecture requires more and more higher to the shock resistance of structure.Traditional beam column connected mode is by the butt weld of complete penetraction and fusion in welding between flange of beam and post, web is with post and use high-strength bolt to be connected, this connected mode does not reach the Seismic Design Requirements of expection, the fracture propagation that starts from addition lower flange of girder edge backing plate and post intersection also can bring damage to steel work to the destruction in the post edge of a wing, and these destructions are main relevant with following factor: the defect that weld seam itself exists, existing rigid connection method causes the stress occurred in the groove weld of the edge of a wing higher, the adverse effect that the shearing that the post gusset plate is excessive and distortion produce, the impact toughness of weld metal is low etc.
As can be seen here, prior art awaits further improving.
The utility model content
The utility model is the weak point of avoiding above-mentioned prior art to exist, and a kind of novel dog bone type bean column node that improves the plastic rotation of node is provided.
The technical scheme that the utility model adopts is:
A kind of novel dog bone type bean column node, comprise steel post and groined type steel plate, described steel post is rectangular steel tube, all opens on four sides of described rectangular steel tube on the rectangular steel tube of upper and lower of the steel plate hole of two bar shapeds and described two steel plate hole and also is fixed with angle steel; Described groined type steel plate is plugged in above-mentioned steel plate hole, and the plate end of described groined type steel plate is connected with dog-bone beam; Described groined type steel plate all is connected by high-strength bolt with angle steel with dog-bone beam and dog-bone beam; Above-mentioned steel post and dog-bone beam form the approximate criss-cross bean column node in a cross section.
The cross section of described dog-bone beam is " work " font, the web that it comprises top flange, bottom flange and connects the described upper and lower edge of a wing, the relative position place of one end on the described upper and lower edge of a wing all offers the first screw and is provided with arc-shaped slot near on the upper and lower edge of a wing of this first screw, and described web offers the second screw with the plate end that above-mentioned groined type steel plate is connected.
One side of described angle steel and square steel pipe welded, another side unsettled and its on offer the 3rd screw.
The plate end of described groined type steel plate all offers the 4th screw equated with above-mentioned the second screw quantity.
Owing to having adopted technique scheme, the obtained beneficial effect of the utility model is:
1, the dog-bone beam in the utility model can form plastic hinge effectively, reduces beam column and is torn the possibility of destruction at Nodes, plays the effect of " earthquake insurance silk "; Turning power and scope that dog-bone beam weakens the corresponding site plastic hinge are larger than turning power and the scope of the plastic hinge at the beam-ends root, take the dog-bone beam of flange of beam weakening, can improve distortion and the energy dissipation capacity of node.
2, the groined type steel plate structure in the utility model is firm, has further improved the globality of bean column node, and node rigidity is larger; In addition, the tube wall of groined type steel plate and rectangular steel tube no longer needs welding, the workload while having reduced construction.
3, the groined type steel plate in the utility model is vertical placement, not only is easy to disturbing concrete, can also guarantee the concrete quality of the joint cores in rectangular steel tube.
4, the quantity of gauge size, high-strength bolt and the corresponding screw of the utility model by controlling angle steel, can control the moment of flexure ability to bear of node, makes node itself have plastic rotation preferably, under the effect of earthquake, and dissipation energy better.
