Description
Technical field
The invention belongs to structural engineering technical field, particularly relate to a kind of through node of dividing plate be connected with steel beam with box shape for rectangular steel-tube concrete column.
Background technology
Encased structures fill concrete in steel pipe is formed, the existence of steel pipe can prevent concrete premature rupture, concrete existence can prevent the too early flexing of steel pipe, the two synergy can give full play to the advantage that steel examining tensile behavior is high and concrete compression performance is good, therefore has that bearing capacity is high, plasticity and good toughness, anti-seismic performance are good, many advantages such as remarkable in economical benefits and construction environmental protection.
Rectangular steel tube with concrete infilled has the advantage that bending rigidity is large, node is easy to connect.The frame structure system that rectangular steel-tube concrete column and girder steel are formed, because layout is flexible, structure simple, component is easy to the features such as standardization, speed of application is fast, cost is low, there is good application prospect in executive information systems, be now subject to the most attention in domestic and international project field.
Conventional rectangular steel-tube concrete column-H profile steel beam connecting node comprises four kinds: inner diaphragm joint, outer ring plate node, the through node of dividing plate and external rib circular board node.Four kinds of nodes all have bolt to weld mixed node, i.e. edge of a wing welding, web bolt connects.
In U.S.'s north ridge earthquake of generation in 1994 and the Japanese Osaka-Kobe earthquake of nineteen ninety-five generation, there is brittle fracture in many connected nodes of multi and tall steel building building, the position of destruction in beam-ends welding position, the gusset plate place etc. of styletable welding position, bean column node.Trace it to its cause and be: on beam, form plastic hinge to reach the object of absorption and dissipation earthquake due to only considered in design at that time, and the stress ignoring nodes domains existence is concentrated and the impact of cross section weakening on node supporting capacity, and weldquality is difficult to ensure the impact on node supporting capacity.And crack is a lot of starts from commissure, bottom flange, the weld seam at this place interrupts, and not easily carries out ultrasonic examination, and weldquality is difficult to ensure.
Shaft blocks by the overhanging two pieces of dividing plates up and down in clapboard radius left and right, has certain weakening to shaft, but integral node section can prefabrication, and site operation process is fairly simple, also contributes to the change realizing column cross-section size in highrise building in addition.Form of architecture joints is simple, easy to make, interior space flexible arrangement.Flange of beam is stressed is directly passed to post side, and power transmission mechanism is clear and definite, is conducive to the transmission of beam-ends bending and shearing, decreases the local distortion of steel pipe post jamb, ensure that the service behaviour of node.But it is large also to there is welding job amount, bottom flange weld seam needs twice welding, and welding quality such as not easily to ensure at the shortcoming.
H profile steel beam is widely used in field of steel structure, and mainly due to its cross sectional shape economical rationality, mechanical property is good.But it is poor around weak axial plane external stability, when some need checking computations stability, often need steel beam with box shape just can meet the demands, but the type of attachment of steel beam with box shape and rectangular steel-tube concrete column node is less.
Summary of the invention
The present invention provides a kind of through node of dividing plate be connected with steel beam with box shape for rectangular steel-tube concrete column for solving in known technology the technical problem that exists, this joints is reasonable, the object that plastic hinge reaches absorption and dissipation earthquake can be formed on beam, bottom flange weld defect can be avoided again the adverse effect of Seismic Behavior, and convenient and quick construction.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of through node of dividing plate be connected with steel beam with box shape for rectangular steel-tube concrete column, comprise the upper spacer and lower clapboard that weld with described rectangular steel-tube concrete column, between described upper spacer and described lower clapboard, be provided with four pieces distinguish relative cantilever plate with the web of described steel beam with box shape, described cantilever plate is connected by junction plate with the web of described steel beam with box shape corresponding thereto; The bottom wing listrium of described steel beam with box shape is overlapped on described lower clapboard, and the two is connected by high-strength bolt I; The top flange plate of described steel beam with box shape is relative with described upper spacer, and is connected by cover plate, and top flange plate and the described upper spacer of described cover plate and described steel beam with box shape weld respectively.
Described junction plate is positioned at the outside of described steel beam with box shape, and described junction plate welds with described cantilever plate, and described junction plate is connected by high-strength bolt II with the web of described steel beam with box shape.
Described junction plate is positioned at the outside of described steel beam with box shape, and described junction plate welds respectively with the web of described cantilever plate and described steel beam with box shape.
The thickness of described cantilever plate is more than or equal to the thickness of the web of described steel beam with box shape; The thickness of described upper spacer is more than or equal to the thickness of the top flange plate of described steel beam with box shape; The thickness of described lower clapboard is more than or equal to the thickness of the bottom wing listrium of described steel beam with box shape.
The advantage that the present invention has and good effect are:
One) form that lower bolt welds is adopted, insensitive to construction and installation error, to be processed and construction error affects less;
Two) weld job of the overwhelming majority completes in factory, and Site Welding workload is little, effectively can reduce the adverse effect of weld defect and extending stress band, can provide good anti-seismic performance.
Three) simple structure, power transmission is clear and definite.Because the bottom flange of steel beam with box shape adopts high-strength bolt to be connected with lower clapboard, the extension of lower clapboard is large, and steel beam with box shape hogging moment area supporting capacity is greatly strengthened.
