Description
Technical field
The present invention is mainly concerned with a kind of building structural element, refers in particular to a kind of node that the concrete-filled circular steel tube column steel beam structure connects that is used for.
Background technology
Concrete filled steel tube has the intensity height, and ductility is good, endurance, and shock resistance is in the engineering such as easily superiority such as construction, so this technology has been successfully applied to high level, strides greatly, heavy duty and antidetonation are explosion-proof.And that concrete-filled circular steel tube column has more the cuff effect is strong, during pressurized footpath (wide) thickness rate can be bigger etc. advantage and gaining great popularity.But the conventional node pattern more complicated of concrete-filled circular steel tube column steel beam structure system becomes the bottleneck that restricts its extensive use.
In the prior art, the connected node of round steel tubing string and girder steel mainly adopts edge of a wing welding, web welding or bolted post connects the node pattern and beam connects the node pattern.But the through node of beam is because the perforation of beam causes the weakening of post bigger, the pouring that has hindered core concrete with vibrate, brought the inconvenience of construction.The through node pattern of existing post mainly contains the outer ring type of putting more energy into, interior reinforcement ring type, and the grappling formula, cross is board-like, and its force-transmission mechanism can be summarized as follows:
Shearing transmits: the main connection with steel beam web plate by high-strength bolt or butt welding by the vertical stiffening rib that is welded on post jamb carried out the shearing transmission.
Moment of flexure is transmitted: mainly weld by outer annular-stiffer plate on the edge of a wing and post table or the post and realize the moment of flexure transmission.Edge of a wing height adds hoop stiffening rib or form anchor the falling part that moment of flexure produces is passed to core concrete in post.
In U.S. Northridge in 1994 earthquake and the Japanese Kobe earthquake in 1996, the through welding node of post suffers serious cracking and brittle fracture, has also just exposed its major defect:
1. the field Welding weldquality is difficult to guarantee, has the crack, owes weldering, fusing is not enough or bad, slag inclusion and pore, because place, beam-ends web bottom flange fabrication hole is less than normal, makes defectives such as in fact the bottom flange weld seam interrupts when welding, and its defective is difficult for inspection again.In addition, weld greatlyyer, cause brittle fracture easily, influence the ductility of node the heat affecting of steel pipe column;
2. there is three-dimensional stress in the steel of connecting portion, can't form side direction and shrink or shearing slip, and the region of high stress of bean column node concentrates on the groove weld place of flange of beam;
3. node is relatively poor to the compliance of structure flexible arrangement, and for example, when the height difference of node periphery girder steel or beam face absolute altitude were inconsistent, joint structure was comparatively complicated.
4. power transmission is unreasonable, and the pulling force of flange of beam can not pass to core concrete effectively, is mainly born by the steel pipe post jamb, causes the cripling distortion of post bigger, influences the supporting capacity of post.
Summary of the invention
The technical problem to be solved in the present invention just is: problems such as brittle fracture big and that caused by welding is serious at the difficulty of construction that exists in the prior art, the invention provides a kind of with low cost, mechanical property good, design is succinctly convenient, difficulty of construction is little, and can avoid field Welding, improve the steel core concrete column node and the manufacture method thereof that beam column is connected that be used for of quality of connection and construction benefit.
In order to solve the problems of the technologies described above, the solution that the present invention proposes is: a kind of concrete-filled circular steel tube column node that is used for the beam column connection, it mainly comprises concrete-filled circular steel tube column and the girder steel that is connected with this post, described concrete-filled circular steel tube column comprises round steel pipe and the concrete of inserting in this round steel pipe, it is characterized in that: on the girder steel beam-ends that is connected with steel core concrete column, be provided with an end plate, be provided with levelling steel plate with ribbing between this steel core concrete column and the described end plate, described levelling steel plate is fixed on the round steel pipe, described end plate, levelling steel plate and round steel pipe link together by a high-strength bolt that passes the post heart.
Rib on the described levelling steel plate can be with erecting rib or cross rib.
A kind of manufacture method that is used for the concrete-filled circular steel tube column node that beam column connects is characterized in that construction sequence is: 1. with end plate and levelling sheet pack auger shell keyhole together, again by the bolt hole position on the levelling steel plate setting circle steel pipe and be drilled to bolt hole; 2. the levelling rib of burn-oning on the levelling steel plate is welded to ribbed steel the round steel pipe surface again, and end plate is welded in the girder steel beam-ends that is connected with steel core concrete column; 3. with the high-strength bolt that passes the post heart end plate, levelling steel plate and round steel pipe are fused, and handle the high-strength bolt surface when avoiding watering post and the bonding of post core concrete, water the core concrete of concrete-filled circular steel tube column then; 4. when core concrete reached certain intensity, the stretch-draw high-strength bolt was to pretension.
Compared with prior art, the present invention has changed for a long time that the round steel tubing string is connected the thinking that adopts welding with girder steel, the related damages of having avoided welding to bring, and its advantage is:
1. node of the present invention has solved the problem that the round steel tubing string is connected with girder steel effectively, saves diaphragm in the rib post, and can well realize the power transmission between beam column.The beam-ends moment of flexure is born by high-strength bolt, and shearing is born by the frictional force between end plate and levelling steel plate, and bolt can also be shared the part shearing in addition, and power transmission is simply distinct, is easy to design, can well guarantee the integral rigidity and the supporting capacity of node again;
2. this node construction technology is simple.Only need the scene to connect steel pipe column and girder steel, high-strength bolt is carried out stretch-draw, economized a large amount of field Welding with high-strength bolt.Site operation difficulty and workload greatly reduce, and help improving efficiency of construction, the reduction of erection time.Cause has avoided field Welding also just to avoid the problem of stress concentration that is caused by weld defect and welding procedure fabrication hole, but has also just improved the application property of structure at cold district in addition.
3. node applying flexible.Connect absolute altitude or the highly different special advantages of Liang Shiyou on the post to handling.
